Description

The present invention relates to a medical equipment installation tool for installing medical equipment such as catheter bags and drainage bags, and portable medical monitors for use with portable ultrasound diagnostic devices.

When surgery is performed in medical facilities, catheterization bags are used to collect urine from urethral catheters, and drainage bags are used to collect bodily fluids such as blood and pus that flow out of drains such as abdominal and diaphragmatic drains, as well as liquids that leak from sutures. When the patient is lying in bed, these bags are hung from the bed so that they are positioned lower than the body so that waste fluids from the body can flow away. In addition, when walking for rehabilitation, moving to treatment rooms, or moving to the toilet, catheterization bags and drainage bags are hung from wheelchairs, IV stands, stretchers, walkers, etc.

These bags are often hung from the railing of a bed by an S-shaped S-hook. However, patients who are in pain and find it difficult to get up often grab the railing, which creates the risk of the S-hook shifting or falling. Also, if the bag is hung from a wheelchair, walker, or stretcher by an S-hook, not only will the patient touch it, but it will also slip when going up a slope (some hospitals have expanded their corridors to include slopes), so it is preferable for the hook to be fixed in place.

As a result, various types of suspenders have been devised for suspending medical bags such as catheterization bags and drainage bags. For example, Patent Document 1 describes a suspender that is attached to a vertical pipe such as an IV stand. Patent Documents 2 and 3 describe suspenders that are attached to a horizontal pipe. Patent Document 4 describes a suspender that is attached to a pipe with an inclined axis that is nearly vertical.

Recently, various medical diagnostic devices have also become smaller, and these diagnostic devices are usually composed of a small measuring device and a small display that shows the results. One example of such a small diagnostic device is a portable ultrasound diagnostic device called Lumify (registered trademark).

The measuring device must be held by the user when in use, but the display that shows the results is installed by leaning it against a wall or using a dedicated stand such as that described in Non-Patent Document 1.

However, none of the hoisting devices in Patent Documents 1 to 4 can be used for pipes with vertical, horizontal, or inclined axes. In addition, they cannot be used for pipes with different shaft diameters.

In addition, when installing a display (portable medical monitor) in a compact diagnostic device, it is obviously unstable if it is leaned against a wall or the like. On the other hand, a dedicated installation stand such as the one described in Non-Patent Document 1 is very expensive, and even if the diagnostic device becomes easier to use by being made smaller, if it becomes necessary to purchase an expensive dedicated stand, its use will not spread.

The present invention aims to provide a medical equipment installation tool that can be installed on pipes with vertical, horizontal or inclined axes so that medical equipment such as medical bags and portable medical monitors can be installed on various medical devices such as beds, IV stands, stretchers and walkers. It also aims to provide a medical equipment installation tool that can be used on pipes of different diameters.

To achieve the above object, the medical equipment installation tool of the present invention is characterized by comprising a holding part for holding the medical equipment, a connector for connecting to the medical device, and a free rotation part for freely rotating the holding part relative to the connector.

When installing medical equipment such as medical bags and portable medical monitors, the medical equipment installation tool of the present invention is equipped with a free rotating section, so it can be used with pipes of vertical, horizontal and inclined axes, and can be widely applied to various medical equipment such as beds, wheelchairs, IV stands, stretchers and rehabilitation walkers. The fact that it can be widely applied to various medical equipment is very preferable, as it eliminates the need to prepare installation tools suitable for each medical equipment, which also leads to cost reduction.

The medical equipment installation tool of the present invention is characterized in that the medical equipment is a medical bag, and the holding part is a hook for hanging the medical bag. In setting up the medical bag, the medical equipment installation tool of the present invention can install the medical bag on a variety of medical instruments, and is highly versatile, compared to conventional hanging tools for installing medical bags.

The medical equipment installation tool of the present invention is characterized in that the medical equipment is a portable medical monitor, and the holding part is a holder that clamps the portable medical monitor. When installing a portable medical monitor, the medical equipment installation tool of the present invention does not require an expensive dedicated stand as in the past, and can be stably installed using a medical instrument.

The holder that holds the portable medical monitor is preferably equipped with a sliding mechanism. The sliding mechanism allows it to accommodate portable medical monitors of different sizes. The holder also preferably holds the portable medical monitor from above, below, left and right.

The medical equipment installation of the present invention is also characterized in that the connector is a clamp. Since it is equipped with a clamp, it can be used with pipes of different diameters within the range of the clamp's specifications, making it applicable to an even greater variety of medical equipment. Wheelchairs, IV stands, rehabilitation walkers, etc. have different pipe diameters depending on the manufacturer, so the fact that it can be widely applied means there is no need to prepare installation tools suitable for each, which also leads to cost savings, making it extremely desirable.

The following describes the mode for carrying out the present invention with reference to the embodiments and drawings, but the embodiments shown below are not intended to limit the present invention to those described herein, and the present invention is equally applicable to those in which various modifications are made without departing from the technical ideas set forth in the claims. Note that in each drawing used for explanation in this specification, each component is shown at a different scale so that each component is large enough to be recognized on the drawing, and is not necessarily shown in proportion to the actual dimensions.
[First embodiment]

The configuration of the main parts of the medical equipment installation tool 100 of the first embodiment will be described using Figures 1 to 3. The medical equipment installation tool 100 of the first embodiment is an installation tool for suspending a medical bag, which is a medical equipment. Figure 1A is an image of a prototype of the medical equipment installation tool 100 of this embodiment, and Figure 1B is a front view showing the configuration of the main parts of Figure 1A. Figure 2A is a plan view of Figure 1B, and Figure 2B is a right side view of Figure 1B. Figure 3A is a view showing the rotation of the free rotation part, and Figure 3B is a cross-sectional view showing the rotation in a direction perpendicular to Figure 3A.

As shown in Figures 1 to 3, the medical equipment installation tool 100 comprises a hook 1 for suspending a medical bag, which is a medical equipment, a free rotating part 2, and a clamp 3. These components are mainly made of surface-treated aluminum, stainless steel, or rubber. The medical equipment installation tool 100 of this embodiment is used to suspend and install medical bags, including urine drainage bags and various drainage bags, on medical equipment such as a bed, a walker, an IV stand, or a wheelchair W.
[Hook part]

The hook 1 is a holder for holding a medical tool, and more specifically, as shown in FIG. 1A, is for hanging a medical bag, which is a medical tool. The hook 1 is made of stainless steel and is screwed into the base 22 of the free rotation part 2.
[Free rotation part]

The free rotation part 2 allows the hook 1 to rotate freely relative to the clamp 3, which is a connector that is connected to the medical instrument, and is made up of a sphere 21 that rotates freely in all directions, up and down, left and right, a base 22 to which the hook 1 is attached, and a single-axis rotor 23 that is attached to the clamp 3 and rotates around one axis. More specifically, as shown in FIG. 3, the free rotation part 2 is made up of the sphere 21, base 22, single-axis rotor 23, first panel 24, second panel 25, lock knob 26, cover 27, and connecting screw 28.

As shown in Figures 3A and 3B, the first panel 24 and the second panel 25 are a pair of panels separated into left and right, housing the sphere 21 above and the single-axis rotor 23 below. The upper part where the first panel 24 and the second panel 25 are joined is open, and the connecting boss 211 of the sphere 21 is exposed from this opening. The lower part where the first panel 24 and the second panel 25 are joined is also open, and the lower part of the single-axis rotor 23 is exposed from this opening.

The upper and lower parts of the spherical surface 212 of the sphere 21 abut against the upper abutment parts 241, 251 and the lower abutment parts 242, 252 of the first panel 24 and the second panel 25, respectively. This allows the sphere 21 to slide on an axis in any direction, making the sphere 21 freely rotatable. The base 22 is attached to the tip of the connecting boss 211 extending from the sphere 21.

An engagement groove 231 is provided on the side of the upper part of the single-axis rotating body 23. A first convex portion 243 and a second convex portion 253 that fit into this engagement groove 231 are provided on the first panel 24 and the second panel 25, respectively. The first convex portion 243 and the second convex portion 253 that fit into the engagement groove 231 allow the single-axis rotating body 23 to rotate about one axis relative to the first panel 24 and the second panel 25.

A connecting screw 28 is screwed into the lower part of the single-axis rotor 23. A male screw 281 is formed below the connecting screw 28, and the male screw 281 connects the single-axis rotor 23 to the clamp 3.

The lock knob 26 is used to stop the free rotation of the sphere 21 and the uniaxial rotation of the uniaxial rotor 23. This lock knob 26 consists of a knob 262, a mounting screw 263 that screws the shaft 261 into the knob 262, and a washer 264.

As shown in FIG. 3A, the shaft 261 is formed with a male thread 2611. The first panel 24 is formed with a through hole 244 into which the shaft 261 fits, and the second panel 25 is formed with a female thread 254 into which the male thread 2611 of the shaft 261 screws. A washer 264 is fitted onto the shaft 261 and inserted into the through hole 244 of the first panel 24, and the male thread 2611 is screwed into the female thread 254 of the second panel 25. This connects the first panel 24 and the second panel 25 while holding the sphere 21 and the one-axis rotor 23.

When the lock knob 26 is rotated to the right, the first panel 24 and the second panel 25 approach each other, and the free rotation of the sphere 21 and the single-axis rotation of the single-axis rotor 23 are locked. When the lock knob 26 is rotated to the left, the first panel 24 and the second panel 25 move apart, and the free rotation of the sphere 21 and the single-axis rotation of the single-axis rotor 23 are unlocked. In this way, since the shaft 261 is located between the sphere 21 and the single-axis rotor 23, the free rotation of the sphere 21 and the single-axis rotation of the single-axis rotor 23 can be locked and unlocked simultaneously by rotating one lock knob 26. The through hole 254 of the second panel 25 is covered with a cover 27 to prevent it from being exposed.

As shown in Figures 1B and 3B, a groove 29, which is a notch that prevents the connecting boss 211 from abutting against it, is formed in the upper part of the part where the first panel 24 and the second panel 25 face each other. Therefore, the base 22 can swing the 360-degree rotation axis of the sphere 21 by θ1 (approximately 90 degrees) to the left and right. In addition, the single-axis rotating body 23, which rotates on one axis, can rotate laterally relative to the first panel 24 and the second panel 25, so the direction of the groove 29 can be freely changed.

The free rotation unit 2 of this embodiment is similar to a rotating body called a free head (or a 3D head, etc.). The configuration of the free rotation unit 2 may be a free head structure different from that of this embodiment.
[Clamp]

As shown in Figures 1 and 2, the clamp 3 is a connector that is connected to a medical instrument, and is made up of a first grip 31, a second grip 32, a rotating shaft 33, an opening/closing shaft 34, and an opening/closing arm 35.

The first gripper 31 and the second gripper 32 rotate to pinch and grasp the pipe P of the medical instrument. As shown in FIG. 1B, the first gripper 31 and the second gripper 32, each of which has a V-shaped bend at the tip, are rotatably supported by a rotating shaft 33. The pinching portions of the first gripper 31 and the second gripper 32 are provided with a first contact portion 311 and a second contact portion 321 made of rubber to prevent the pipe P from being damaged.

The first grip 31 has a first shaft 312 along with a rotation shaft 33. The second grip 32 has a second shaft 322 along with a rotation shaft 33. The first shaft 312 and the second shaft 322 have a first female thread and a second female thread (not shown) cut at right angles to the rotation shaft.

The opening/closing shaft 34 has a first male screw 341 and a second male screw 342 (see FIG. 1) that screw into the first and second female screws, respectively. A hole is formed at the end of the opening/closing shaft 34, and an opening/closing arm 35 for rotating the opening/closing shaft 34 is slidably installed in this hole. Note that stoppers 351 are formed by crushing both ends of the opening/closing arm 35 to prevent the opening/closing arm 35 from sliding off the opening/closing shaft 34.

Here, the first male screw 341 and the second male screw 342 of the opening/closing shaft 34 are threads that rotate in opposite directions. Therefore, when the opening/closing arm 35 is rotated clockwise in FIG. 2A, the tips of the first grip 31 and the second grip 32 rotate in a closing direction (see FIG. 1A) around the rotation axis 33. On the other hand, when the opening/closing arm 35 is rotated counterclockwise in FIG. 2A, the tips of the first grip 31 and the second grip 32 rotate in an opening direction (see FIG. 1A).

The size of the clamping area between the first gripper 31 and the second gripper 32 can be changed by the amount of rotation of the opening/closing shaft 34, so the diameter of the pipe P to be gripped may be different. Also, since the first gripper 31 and the second gripper 32 grip the V-shaped tip side, the cross section of the pipe P to be gripped does not necessarily have to be circular. Also, the shape of the clamp 3 is naturally not limited to this embodiment, and other shapes are acceptable as long as it is a connector that can be detachably connected to the pipe P.

In this way, in the medical instrument installation tool 100 of this embodiment, the hook 1, which is a holding part that holds the medical instrument, is connected to the clamp 3 via the free rotation part 2. The base 22 of the free rotation part 2 to which the hook 1 is attached can be moved left and right by θ1 (approximately 90 degrees) by a groove 29 formed in the upper part of the part where the first panel 24 and the second panel 25 face each other as shown in FIG. 3B, and the position of this groove 29 can be rotated by the single-axis rotor 23 connected to the clamp 3.

Therefore, the medical equipment installation tool 100 of this embodiment can attach the hook 1 at a desired angle regardless of whether the pipe P to which the clamp 3 is attached is horizontal, vertical, or inclined. Figures 1 and 2 show a first example of use in which the medical equipment installation tool 100 of this embodiment is attached to a horizontal pipe P such as a bed rail or walker.

Figure 4 shows a second example of use in which the medical equipment installation tool 100 of this embodiment is attached to a vertical pipe P of an IV stand, walker, wheelchair W, etc. Figure 5 shows a third example of use in which the medical equipment installation tool 100 of this embodiment is attached to an inclined pipe P of a wheelchair W, walker, etc.

In addition, in use examples 1 to 3, the medical instrument installation tool 100 is used with the hook 1 oriented horizontally. However, the use examples of the medical instrument installation tool 100 of this embodiment are not limited to the orientation of the hook 1 oriented horizontally.

For example, as shown in use example 4 on a wheelchair W in FIG. 6A, the hook 1 may be used facing upward. FIG. 6B shows a medical bag B made of a urine drainage bag hung from the medical equipment installation tool 100 in FIG. 6A. In this use example, the distance between the medical bag B and the floor is increased, which further prevents the medical bag B from coming into contact with the floor.

However, if the urine drainage bag comes into contact with the floor, there is a risk that the patient may become infected through the urinary catheter extending from the urine drainage bag. The medical equipment installation tool 100 can prevent such infections by using it in the example shown in Figure 6. The risk of infection from the urine drainage bag can also occur when the tires of the wheelchair W come into contact with the medical bag B. However, the medical equipment installation tool 100 can be attached not only to the vertical pipe shown in the example of use of the wheelchair W in Figure 6, but also to an inclined pipe located in front of it. This example of use can increase the distance from the rear wheels of the wheelchair W, preventing infection from contact with the tires.

In addition, the medical equipment installation tool 100 of this embodiment uses the clamp 3 as a connector, but other connectors (such as a fixing belt) can also be used. However, the medical equipment installation tool 100 of this embodiment uses the clamp 3 as a connector, and the clamp 3 makes it easy to attach and detach the medical equipment. In addition, since the medical equipment installation tool 100 is attached using the clamp 3 of this embodiment, it can be attached even if the diameter of the pipe P is different, as long as it is within the specification range of the clamp 3. For example, the specification range of the clamp 3 of this embodiment is 15 mm to 44 mm, and it can be attached to a thin connecting pipe that is horizontal on a walker (walking frame) or a thick support that connects the arm support part and caster part of a walker.

In addition, while the medical equipment installation tool 100 in this embodiment has one hook 1 as a holding part, it may have two hooks or more, such as a bifurcated hook. By having multiple hooks, the medical equipment installation tool can stably hang a medical bag, which is a medical equipment. Also, by having multiple hooks, the medical equipment installation tool can be used to hang and install not only medical bags, but also other items (for example, when used on a bed, a garbage bag can be hung on one side).

Furthermore, the medical equipment installation tool 100 may be used to hang not only urine catheter bags and drainage bags but also blood transfusion bags. Blood transfusion bags are normally used with an intravenous drip stand, but there may be cases where an intravenous drip stand cannot be secured, such as during a disaster or outdoors during a disaster. Even in such cases, if the medical equipment installation tool 100 of this embodiment is used, it is possible to hang a blood transfusion bag using a nearby pipe-shaped object.
[Second embodiment]

The configuration of the medical equipment installation tool 100A of the second embodiment will be described using Figures 7 and 8. The medical equipment installation tool 100A of this embodiment is an installation tool for installing a portable medical monitor M, which is a medical equipment, on an IV stand S. Figure 7A is an image of the medical equipment installation tool 100A of the second embodiment, and Figure 7B is a front view showing the configuration of the main parts of the second embodiment. Figure 8A is an image of the side showing the state in which the medical equipment installation tool 100A is attached to the IV stand S, and Figure 8B is an image of the side showing Example 5 of Use in which the portable medical monitor M is attached to Figure 8A.

In the medical equipment installation tool 100A of this embodiment, parts that have the same configuration as the medical equipment installation tool 100 of the first embodiment are given the same reference numerals and detailed descriptions are omitted, and parts with the same names but different configurations are given the suffix "A" after the reference numerals.

As shown in Figures 7 and 8, the medical equipment installation tool 100A is composed of a holder 4 that holds a portable medical monitor M, which is a medical equipment, a free rotation part 2A to which the holder 4 is connected, and a clamp 3 to which the free rotation part 2A is connected.

As an example of the portable medical monitor M, which is a medical tool, the portable medical monitor M used in the Lumify (registered trademark) portable ultrasound diagnostic device is conceivable. However, it may also be a portable medical monitor used in other small diagnostic devices. For example, a portable medical monitor used in a diagnostic device such as a small electrocardiogram is conceivable.

The holder 4 is a holding part that holds a medical tool, and as shown in FIG. 8B, is for clamping a portable medical monitor M, which is a medical tool. More specifically, the holder 4 has a pair of holding parts 41 that clamp the portable medical monitor M. The pair of holding parts 41 are formed with V-shaped parts 411, and as shown in FIG. 8A, they are V-shaped. The pair of holding parts 41 are biased in directions that bring them closer to each other by a biasing means (not shown).

Then, after stretching the holding parts 41 in the direction of pulling them apart (from (A) to (B) in FIG. 8), the portable medical monitor M is sandwiched between them, and the portable medical monitor M is held in the holder 4 by the biasing force of the holding parts 41. In this way, the holding parts 41 are equipped with a sliding mechanism that uses the biasing force.

As such a holder 4, for example, the "SLIK Smartphone & Tablet Holder" sold by Kenko Tokina Co., Ltd. can be used. However, the holder 4 is not limited to the one exemplified here, and any holder that can hold the portable medical monitor M by clamping or screwing it in place can be used.

The free rotation part 2A is the free rotation part 2 of the first embodiment without the base 22, and the holder 4 and the free rotation part 2A are connected by screwing the connecting boss 211 into the holder 4. The method of connecting the free rotation part 2A and the clamp 3 is the same as in the first embodiment.

With this configuration, the medical instrument installation tool 100A of the second embodiment, like the first embodiment, can attach the holder 4 at a desired angle regardless of whether the pipe P to which the clamp 3 is attached is horizontal, vertical, or inclined.

Figures 8B and 9A show a fifth example of use of the medical instrument installation tool 100A of this embodiment, in which the medical instrument installation tool 100A is attached to an intravenous stand S. Figure 9B shows a sixth example of use, in which the portable medical monitor M is rotated 90 degrees by rotating the connecting boss 211 from the state shown in Figure 9A.

In this manner, the medical equipment installation tool 100A of the present embodiment can install the portable medical monitor M on the infusion stand S, which is a medical equipment, by using the holder 4, which is a holding part for holding the portable medical monitor M, which is a medical equipment. Therefore, the portable medical monitor M can be installed very stably compared to the case where it is leaned against a wall or the like. In addition, since the infusion stands S, which are abundant in medical sites, or the pipes P of medical equipment such as beds, stretchers, rehabilitation walkers, and wheelchairs can be used to install the portable medical monitor M, by using the medical equipment installation tool 100A, an expensive dedicated installation stand is not required. In addition, the fact that the portable medical monitor M can be installed in this manner using the medical equipment installation tool 100A is very effective, for example, in disaster sites, etc.
[Third embodiment]

Next, the configuration of the medical equipment installation tool 100B of the third embodiment will be described with reference to FIG. 10. The medical equipment installation tool 100B of this embodiment is an installation tool for installing a portable medical monitor M, which is a medical equipment, on an intravenous stand S (an example of a medical instrument), similar to the second embodiment. FIG. 10A is a front view of the medical equipment installation tool 100B of the third embodiment, FIG. 10B is a top view thereof, and FIG. 10C is a left side view thereof.

In the medical equipment installation tool 100B of this embodiment, parts that have the same configuration as the medical equipment installation tool 100 of the first embodiment and the medical equipment installation tool 100A of the second embodiment are appropriately given the same reference numerals and detailed descriptions are omitted, and parts with the same names but different configurations are given the suffix "B" after the reference numerals.

The medical equipment installation tool 100B, like the medical equipment installation tool 100A of the second embodiment, is made up of a holder 4B that clamps the portable medical monitor M, which is a medical equipment, a free rotation part 2B to which the holder 4B is connected, and a clamp 3B to which the free rotation part 2B is connected. However, the structure of the holder 4B that clamps the portable medical monitor M of this medical equipment installation tool 100B is significantly different from that of the medical equipment installation tool 100A of the second embodiment.

The holder 4B is a holding section that holds medical equipment and is intended to clamp the medical monitor M. More specifically, as shown in FIG. 10, the holder 4B includes a plate-shaped base plate 44, an upper holding section 45, a right holding section 46, a left holding section 47, a first lower holding section 48, and a second lower holding section 49.

As shown in Fig. 11A, from the front view of Fig. 10A, this holder 4B is designed so that the upper holding part 45 can slide upward and the left holding part 47 and the second lower holding part 49 can slide leftward relative to the rectangular base plate 44. This point will be explained in detail. Note that Fig. 11B is an exploded view of the holder 4B.

The upper holding part 45 consists of a hook-shaped receiving part 45a and a guide piece 45c in which an opening 45b consisting of a long hole for sliding is formed. For reference, a side view of the upper holding part 45 is shown in the area enclosed by a dashed line on the left side of FIG. 11B.

The left holding part 47 and the second lower holding part 49 are made of a single integrally formed part as shown in FIG. 11B, and each has a hook-shaped receiving part 47a and receiving part 49a, and also has a guide piece 47c with an opening 47b formed of a common long hole for sliding. For reference, in FIG. 11B, a side view of the left holding part 47 and the second lower holding part 49 is shown in the area enclosed by the dashed line below.

The right retaining part 46 consists of a hook-shaped receiving part 46a and a fixing piece 46c with two fixing holes 46b formed therein. For reference, a side view of the right retaining part 46 is shown in the area enclosed by a dashed line above in FIG. 11B. The first lower retaining part 48 has the same structure as the right retaining part 46, so a description thereof will be omitted.

The upper holding portion 45 is attached to the base plate 44 on the rear side of the base plate 44 by a knurled knob 51 (see FIG. 10B) that is knurled through a mounting hole 44a provided in the base plate 44 and a bolt 51a.

The left holding part 47 and the second lower holding part 49, which are integral parts, are attached to the base plate 44 on the rear side of the base plate 44 by a knurled knob 52 (see FIG. 10B) and a bolt 52a through an attachment hole 44b provided in the base plate 44. In addition, a step 44e (see FIG. 10C) is provided on the rear side of the base plate 44 to prevent interference between the guide piece 47c and the guide piece 45c of the upper holding part 45.

The right retaining portion 46 is attached to the base plate 44 by bolts (not shown) through two mounting holes 44c provided in the base plate 44 on the rear side of the base plate 44. Similarly, the first lower retaining portion 48 is attached to the base plate 44 by bolts (not shown) through two mounting holes 44d provided in the base plate 44 on the rear side of the base plate 44.

For example, when sliding the upper holding part 45 from the state shown in FIG. 10A to the state shown in FIG. 11A (or vice versa), first rotate the knurled knob 51 in the loosening direction to slide the guide piece 45c, and then rotate the knurled knob 51 in the tightening direction to fix the guide piece 45c. Similarly, when sliding the left holding part 47 and the second lower holding part 49 from the state shown in FIG. 10A to the state shown in FIG. 11A, this is done in a similar manner using the knurled knob 52. In this way, the holder 4B is provided with a sliding mechanism for the upper holding part 45 and the left holding part 47 and second lower holding part 49, which are integral parts.

With the holder 4B configured in this way, for example, if the portable medical monitor M is about 7 inches in size, the medical monitor M can be fixed in the state shown in FIG. 10A, and if it is about 12.9 inches in size, the medical monitor M can be fixed in the state shown in FIG. 11A. Furthermore, this holder 4B can be used regardless of whether the portable medical monitor M is a portrait or landscape type.

In addition, because medical portable monitors M are required to be highly durable and shock-resistant, they are thicker than typical monitors, and may be as thick as about 24 mm. The inventors conducted various tests to ensure that such thick monitors could be held securely, and found that the size of receiver 45a shown in FIG. 11B was suitable for receivers 45a, 46a, 47a, 48a, and 49a of each holder. It is also advisable to attach cushioning material 53 (four places in this embodiment) to the surface of base plate 44 to increase shock resistance.

The free rotation part 2B is substantially the same as the free rotation part of the first and second embodiments, and a base 22B for fixing to the holder 4B is provided at the tip of the connecting boss 211. A connection plate 54 is fixed to this base 22B with a bolt, and the connection plate 54 is fixed to the back of the holder 4B with a bolt via the (four) fixing holes 44f in the base plate.

In this embodiment, the clamp 3B has a structure known as a C-clamp. In FIG. 10B, the jaw 37 at the end of the screw 36 and the handle 38 of the clamp 3B are shown in two states (open and closed). The clamp 3B can be used to fix the medical equipment installation tool 100B to a variety of objects present in the medical field, such as pipe-shaped objects (e.g., an IV stand) or plate-shaped objects (e.g., a table).

Figure 12A is an image of the medical equipment installation tool 100B attached to an IV stand S, and Figure 12B is an image of usage example 7 with a portable medical monitor M attached. Also, Figure 13A is an image of usage example 7 diagonally from the back left, and Figure 13B is an image of usage example 7 diagonally from the back right. The medical equipment installation tool 100B of this embodiment can actually be used in this manner.

The medical equipment installation tool 100B, like the first embodiment, is equipped with a single-axis rotor 23 in the free rotation section 2B, and the single-axis rotor 23 can be unlocked by rotating the lock knob 26. This allows the portable medical monitor M to be rotated 90 degrees for use by rotating the single-axis rotor 23.

In this way, the medical equipment installation tool 100B of this embodiment can install the portable medical monitor M on the infusion stand S, which is a medical equipment, by using the holder 4B, which is a holding part that holds the portable medical monitor M of the medical equipment. Therefore, the portable medical monitor M can be installed very stably compared to leaning it against a wall or the like. In addition, since the infusion stands S, which are abundant in medical sites, or the pipes P of medical equipment such as beds, stretchers, rehabilitation walkers, and wheelchairs can be used to install the portable medical monitor M, by using the medical equipment installation tool 100B, an expensive dedicated installation stand is not required. In addition, being able to install the portable medical monitor M in this way using the medical equipment installation tool 100B is very effective, for example, in disaster sites. In addition, since the holder in the second and third embodiments is equipped with a slide mechanism, it can accommodate portable medical monitors M of various sizes. In particular, when a different portable medical monitor M needs to be used suddenly, a slide mechanism that can accommodate various sizes is important.

Furthermore, the medical equipment installation tool 100B is configured with upper, lower, left and right holding parts so that it can hold the portable medical monitor M from above, below, left and right, so that it can hold the portable medical monitor M more firmly than the medical equipment installation tool 100A of the second embodiment. In addition, the upper holding part 45 can slide upward, and the integrated left holding part 47 and second lower holding part 49 can slide leftward, and the right holding part 46 and the first lower holding part 48 are fixed to the base plate 44, so that when holding monitors of different sizes, it is not necessary to adjust each of the four sides. Therefore, the medical equipment installation tool 100B only needs to adjust the other holding parts by sliding them based on the right holding part 46 and the first lower holding part 48. Such a structure is very preferable in medical settings where emergency situations are required or where reliability is required with as few operations as possible.

The medical equipment installation tool 100B clamps the lower part of the portable medical monitor M with two parts, the first lower holding part 48 and the second lower holding part 49, so that the monitor can be clamped more reliably and stably. When clamping the portable medical monitor M using the medical equipment installation tool 100B, first set the lower part of the portable medical monitor M into the receiving part 48a of the first lower holding part 48 and the receiving part 49a of the second lower holding part 49, and the right side of the portable medical monitor M into the receiving part 46a of the right holding part 46. This creates a very stable state, making subsequent work very easy to carry out.
