JP7061014B2 - Connecting tool for IV stand - Google Patents

Description

The present invention relates to a connector for a drip stand. More specifically, the present invention relates to a drip stand connector for connecting a drip stand to a moving device such as a wheelchair, a stretcher or a rehabilitation walker.

In medical facilities, patients undergoing IV drip may carry a drip stand with casters and move with a moving device such as a wheelchair, stretcher, or rehabilitation walker. At this time, a drip stand connector for connecting the drip stand to the moving device was considered so that the person does not have to hold the drip stand.

For example, Patent Document 1 describes a drip stand connector in which one end of a flexible rod is fixed to a wheelchair or a stretcher, and a hook-shaped attachment member attached to the other end is attached to the drip stand.

Patent Document 2 describes a drip stand connector for connecting a drip stand to a wheelchair by providing a grip for gripping both parallel handles of the wheelchair and a crossbar connecting means for connecting to the crossbar below the wheelchair. When not in use, the grip that extends to the left and right is removed from the steering wheel and rotated downward to close, and the crossbar connecting means protruding forward is removed from the crossbar of the wheelchair and rotated downward. In this way, when not in use, the drip stand connector remains attached to the drip stand.

Patent Document 3 describes a drip stand connector for connecting a drip stand to a wheelchair by providing clamps at both ends of the connecting rod. These two clamps can rotate on axes parallel to each other and be fixed to the connecting rod at any angle, so if the drip stand and the axis of the wheelchair cylinder are on the same plane, they can be at different heights. Can be linked. Further, as shown in FIG. 2 of the publication, when not in use, the drip stand cylinder is stored with both clamps of the drip stand connector attached.

Wheelchairs and stretchers to which a drip stand with casters is connected have various shapes, and a drip stand connector that can connect the drip stand to any shape and position is preferable. Further, it is preferable that the connecting tool for the drip stand can be connected to a rehabilitation walker not described in Patent Documents 1 to 3. Further, it is preferable that the drip stand connector can easily move the drip stand to the front, back, side, etc. of a moving device such as a wheelchair depending on the situation such as passage in a corridor or getting on and off an elevator. Further, it is preferable that the connecting tool for the drip stand can be compactly accommodated when not in use. It is also preferable that it can be easily applied to a reclining wheelchair or a stretcher. As described above, many things are desired for the connecting tool for the drip stand, which is mainly used in the hospital.

On the other hand, in the drip stand connector of Patent Document 1, since the flexible rod body is not a rigid body, the relative position between the drip stand and the moving device cannot be fixed. For this reason, the flexible rod body is unexpectedly deformed during movement and the relative position between the drip stand and the moving device changes, which is not preferable because there is a risk of drip leakage.

The drip stand connector of Patent Document 2 can be applied only to a wheelchair having a parallel handle and a crossbar. Also, the IV stand can only be connected to the rear of the wheelchair, and the applicable mobile equipment is very limited.

The drip stand connector of Patent Document 3 can be connected to the inclined pipe-shaped portion of the moving device only at the position of the support of the drip stand on the same surface as the pipe-shaped portion. For example, for a wheelchair with its wheels tilted forward, an upright IV stand cannot be connected to the side of the wheelchair. Further, since the distance between the two clamps is always constant, the occupied area for traffic and bicycle parking is large. Further, when not in use, if the drip stand connector is removed from the drip stand and tried to be accommodated on the moving instrument side, it will greatly protrude, so that it is difficult to accommodate the drip stand on the moving instrument side.

It is an object of the present invention to provide a general-purpose drip stand connector that can be widely applied to various shapes of mobile devices such as wheelchairs, stretchers and rehabilitation walkers. Another object of the present invention is to provide a drip stand connector that can easily change the position of the drip stand to the front, back, side, etc. of the moving device and can be compactly stored when not in use.

In order to achieve the above object, the drip stand connector of the present invention includes a first clamp attached to the drip stand side, a second clamp attached to the moving device side, and the first clamp and the second clamp. A drip stand connector for connecting the drip stand to the moving device, comprising a connecting rod to be held, wherein at least one position of the first clamp and the second clamp is on the connecting rod 1. It is characterized by being movable along.

This makes it possible to easily adjust the distance between the moving device and the drip stand. Also, when the drip stand connector is not in use, the drip stand connector is attached to either the drip stand or the moving device, and only the other is removed to shorten the distance between the first clamp and the second clamp. Then, the drip stand connector can be compactly stored in the moving device or the drip stand. For example, the drip stand connector can be pushed into the stretcher S to reduce the protrusion from the caster.

Further, in the drip stand connector of the present invention, the first clamp and the second clamp can be rotated and fixed on axes parallel to each other, and the first clamp and the second clamp can be fixed. It is preferable that at least one of the above can be rotated and fixed in an axial direction other than the parallel axis.

As a result, at least one of the first clamp and the second clamp can rotate in the other axial direction, so that the drip stand and the cylinder of the moving device have different heights even if they are not on the same plane. The first clamp and the second clamp can be attached with. For example, a drip stand can be connected to the side of a wheelchair even in a wheelchair with the legs of the wheels tilted forward. This will increase the variety of mobile devices such as wheelchairs to which a drip stand with casters can be connected.

Further, in the connecting tool for a drip stand of the present invention, it is preferable that the first clamp and the second clamp are held by the connecting rod so as to be rotatable in a biaxial direction or a free direction.

As a result, the drip stand can be moved back and forth or sideways of the moving device depending on the situation while the drip stand connecting tool is connected to the drip stand and the moving device. For example, move the IV stand behind the moving device when moving in a narrow space, and move the IV stand to the side of the moving device when moving in a short depth elevator. Further, when the moving device has a reclining function, the angle of the backrest of the moving device can be changed while the drip stand connector is attached to the moving device.

[Embodiment]
The configuration of the main part of the connecting tool 100 for the drip stand of the embodiment will be described with reference to FIGS. 1 to 5. The drip stand connector 100 connects the drip stand D with casters to a moving device such as a wheelchair W, a stretcher S, or a rehabilitation walker R. The drip stand D, the wheelchair W, the stretcher S, and the rehabilitation walker R are shown in FIGS. 6 and later.

The drip stand connector 100 has a connecting rod 1, a free rotating portion 2 fixed to one end of the connecting rod 1, and a first clamp that is freely rotatable and can be fixed at an arbitrary angle to the free rotating portion 2. 3, a sliding portion 4 that is slidably and rotatably held by the connecting rod 1 and can be fixed at an arbitrary position and angle, a biaxial rotating portion 5 fixed to the sliding portion 4, and a biaxial rotating portion. It consists of a second clamp 6 which is rotatably attached to 5 and can be fixed at an arbitrary angle. The material of these components mainly consists of surface-treated aluminum and acrylic.

The connecting rod 1 has a diameter of about 48 mm and a length of about 400 mm, and has a lid for preventing the sliding portion 4 from coming off and closing the cylinder at the other end opposite to the one end where the free rotating portion 2 is fixed. 11 is fixed.

The free rotation unit 2 has the same configuration as a general free platform, and has a ball 21, a support column 22 to which the first clamp 3 is fixed integrally with the ball 21, and a support column 22 protruding from the ball 21. It is composed of a ball holding portion 23 having an opening partially exposed and holding the ball 21 so as to be freely rotatable, and a free rotation fixing screw 24 attached to the ball holding portion 23 to fix the free rotation of the ball 21.

The first clamp 3 is a frame 31 having a "U" shape (a shape close to a U shape) fixed to the support column 22 of the free rotating portion 2, and two first axes 32 penetrating the opposite sides of the frame 31. Each consists of a first handshake 33 and a second handshake 34 whose one end is rotatably supported by an axis, and a grip screw 36 which is rotatably supported by a second shaft 35 at the other end of the first handshake 33.

The first handshake 33 and the second handshake 34 rotate to sandwich and grip the drip stand D or the pipe-shaped portion P of the moving device, and each sandwiched portion has an acrylic V-shaped contact portion. 37 is provided. Since the contact portion 37 is made of synthetic resin acrylic, it is difficult to damage the drip stand D and the moving device.

With the drip stand D or the moving device sandwiched between them, the grip screw 36 pivotally supported by the first handshake 33 is fitted into the notch groove 38 of the second handshake 34, and into the stopper 39 provided in the second handshake 34. It is screwed in at the abutted position. As a result, the distance between the first handshake 33 and the second handshake 34 in the sandwiched state is grasped, the screw 36 is shortened, and the first clamp 3 is firmly fixed to the drip stand D or the moving device. Since the dimensions sandwiched between the first handshake 33 and the second handshake 34 can be changed by the gripping screw 36, the diameter of the pipe-shaped portion P to be gripped may be different. Further, since the pipe-shaped portion P to be gripped is sandwiched between the two V-shaped contact portions 37, the cross section of the pipe-shaped portion P to be gripped does not necessarily have to be circular. In this embodiment, the second clamp 6 is a common component having the same shape as the first clamp 3.

The sliding portion 4 includes a sliding cylinder 41 having a groove 411 and a sliding cross section having a C-shape, and a sliding fixing screw 42 that narrows the width of the groove 411 to fix sliding and rotation. It is composed of a connecting portion 43 having a hole (not shown) rotatably held in the biaxial rotating portion 5 integrally with the cylinder 41.

The biaxial rotating portion 5 rotates the sliding portion 4 by screwing the shaft 51 to which the second clamp 6 is fixed, the biaxial fixing screw 52, and the biaxial fixing screw 52 through the holes. It is composed of a biaxial holding portion 53 that holds the shaft 51 rotatably and holds the shaft 51 rotatably.

As shown in FIG. 5, the biaxial holding portion 53 includes a C-shaped hole 531 having a C-shaped cross section into which the shaft 51 is fitted, and a female screw 532 into which the biaxial fixing screw 52 is screwed. The axis of the hole 531 and the axis of the female screw 532 are orthogonal to each other. Therefore, when the biaxial fixing screw 52 is screwed, the sliding portion 4 is tightened to the biaxial holding portion 53, and the relative rotation angle between the sliding portion 4 and the biaxial rotating portion 5 is fixed. At the same time, the width of the C-shaped notch portion is narrowed to stop the rotation of the shaft 51, so that the relative rotation angle between the second clamp 6 and the biaxial rotating portion 5 is also fixed.

As described above, in the drip stand connecting tool 100 of the present embodiment, the first clamp 3 capable of freely rotating and fixing the rotation by the free rotating portion 2 to one end of the connecting rod 1 and the connecting rod 1 by the sliding portion 4 are attached. It is configured to be provided with a second clamp 6 that can slide / rotate, can fix the sliding / rotation, and can rotate in the biaxial direction and fix the rotation by the biaxial rotating portion 5.

As a result, the first clamp 3 and the second clamp 6 can rotate on axes parallel to each other. Therefore, if the angles of the axes of the pipe-shaped portions P to be gripped are the same plane, the first clamp 3 and the second clamp 6 It can be connected even if the gripping height changes. Further, since at least one of the first clamp and the second clamp can rotate in an axial direction other than the parallel axis, the first clamp 3 and the first clamp 3 and the first clamp even if the angle of the axis of the pipe shape portion P to be gripped is not the same plane. 2 Clamps 6 can be connected even if the gripping height changes. Further, since the distance between the first clamp 3 and the second clamp 6 can be changed along the connecting rod 1, the gripped position may be changed while gripping both. Further, when not in use, one of the first clamp 3 and the second clamp 6 can be removed and the other clamp can be attached to compactly accommodate the drip stand connector 100. Further, the first clamp 3 and the second clamp 6 can be applied to different diameters and shapes of the pipe shape portion P of the moving device. The drip stand D may be attached to either the first clamp 3 or the second clamp 6.

[First use example]
Next, a first use example of the drip stand connector 100 of the embodiment will be described with reference to FIG. As shown in FIG. 6A, the first clamp 3 is attached to the stretcher S, and the second clamp 6 is attached to the drip stand D.

When the drip stand connector 100 is not used, as shown in FIG. 6B, only the first clamp 3 is removed from the drip stand D while the second clamp 6 is attached to the stretcher S, and the sliding portion 4 slides. The connecting rod 1 and the first clamp 3 are pushed into the stretcher S and stored compactly. At this time, since it is not necessary to attach the second clamp 6 to the stretcher S at the time of use, the attachment time of the drip stand connector 100 can be shortened, which is highly effective in an emergency.

When not in use, conversely, only the second clamp 6 is removed, the connecting rod 1 and the second clamp 6 are rotated by the rotation of the free rotating portion 2, and the second clamp 6 is attached to the drip stand D to attach the drip stand. The connecting tool 100 may be stored in the support column of the drip stand D. Even at this time, since the separation distance between the first clamp 3 and the second clamp 6 can be shortened by sliding the sliding portion 4, the drip stand D can be accommodated without removing both the clamps 3 and 6.

[Second usage example]
Next, a second use example of the drip stand connector 100 of the embodiment will be described with reference to FIG. 7. The first clamp 3 is attached to the drip stand D, and the second clamp 6 is attached to the wheelchair W. The drip stand D is arranged next to the wheelchair W.

In this state, when the drip stand D is moved behind the wheelchair W, the first clamp 3 and the second clamp 6 remain attached to the drip stand D and the wheelchair W. That is, the first clamp 3 is in a state where it can be freely rotated after being released from being fixed by the free rotation fixing screw 24 (not shown in FIG. 7, see FIG. 2). Further, the second clamp 6 is in a state where it can be slid / rotated and biaxially rotatable after being released from being fixed by the sliding / rotating fixing screw 42 and the biaxial fixing screw 52.

Therefore, the direction of inclination of the connecting rod 1 can be changed by the free rotation of the first clamp 3 and the rotation of the second clamp 6. Further, the separation distance between the first clamp 3 and the second clamp 6 can be changed by sliding the second clamp 6. Therefore, the first clamp 3 and the second clamp 6 can move the drip stand D behind the wheelchair W even while they are attached to the drip stand D and the wheelchair W. Conversely, the drip stand D can be moved sideways from behind the wheelchair W.

For example, when moving the wheelchair W with the drip stand D, it is easier to move if the drip stand D is next to the wheelchair W. However, in narrow corridors and narrow elevators, the IV stand D should be behind the wheelchair W. The same applies to the stretcher S of the first use example. That is, since the stretcher S is long, it is better that the drip stand D is next to the stretcher S when the drip stand D is connected to the stretcher S and the elevator has a narrow depth.

As described above, the drip stand connector 100 of the present embodiment can easily move the position of the drip stand D according to the situation without removing the first clamp 3 and the second clamp 6. It is also easy to turn right or left. It should be noted that it is very preferable that the position of the drip stand D can be easily moved according to the situation not only for the person using the moving device but also for the person who cares in the vicinity thereof.

[Third use example]
Next, a third use example of the drip stand connector 100 of the embodiment will be described with reference to FIGS. 8 and 9. FIG. 8 is an image pickup in which the drip stand connector 100 changes the tilt of the reclining while the drip stand D and the wheelchair W with reclining are connected, and FIG. 9 is a diagram illustrating an operation in which the reclining is tilted in the direction of lying down. be.

In FIG. 9, the point O is the center of rotation of the reclining wheelchair W. Point A is the center of rotation of the second clamp 6. Points B1 to B3 are centers where the first clamp 3 rotates.

By tilting the reclining in the laying direction, the center of rotation of the first clamp 3 moves from the point B1 to B3. Here, the point B2 is a position when the center of rotation of the first clamp 3 is on the extension of the points O and A. Of B1, B2, and B3, the point A is closest to the point B2. This can be seen from the triangles B1 ・ O ・ A and the triangles B3 ・ O ・ A. That is, due to the sliding of the second clamp 6, the distance between the first clamp 3 and the second clamp 6 becomes the shortest when the center of rotation of the first clamp 3 is at the position of B2. In this way, the distance between the first clamp 3 and the second clamp 6 due to reclining changes.

Further, since the angle α1 formed by the lines B1 and O and the line B1 and A is positive and negative opposite to the angle α3 formed by the lines B3 and O and the lines B3 and A, the first clamp 3 has the absolute value of α1 and α3. It will be rotated by the sum of the absolute values of. On the other hand, the second clamp 6 rotates by the angle β, which is the angles B1, A, and B3. As described above, the rotation angle of the first clamp 3 and the rotation angle of the second clamp 6 due to reclining are different.

In this way, in the drip stand connector 100 of the present embodiment, both the first clamp 3 and the second clamp 6 can rotate in parallel with the reclining axis, and the second clamp 6 slides to the second clamp. Since the distance between the 1 clamp 3 and the 2nd clamp 6 can be changed, the reclining angle can be easily changed without removing the 1st clamp 3 and the 2nd clamp 6. Since the first clamp 3 is a free rotation and the second clamp 6 is a biaxial rotation and a rotation of the sliding portion 4, the reclining angle is lightly changed even if there is a mounting error of the drip stand connector 100. can do.

[Fourth usage example]
Next, a fourth use example of the drip stand connector 100 of the embodiment will be described with reference to FIG. In FIG. 10, the drip stand connector 100 connects the drip stand D and the rehabilitation walker R. During use in the rehabilitation walker R, a situation may occur in which the user himself / herself moves the drip stand D according to the surrounding environment while walking. Therefore, the drip stand connector 100 that can correspond to various positional relationships between the rehabilitation walker R and the drip stand D is very preferable. As described above, the drip stand connector 100 of the present embodiment can be applied to mobile devices other than the stretcher S and the wheelchair W.

In the drip stand connector 100 of the present invention, the first clamp 3 may be held so as to be biaxially rotatable, or the second clamp 6 may be held so as to be freely rotatable. Further, regarding sliding, at least one of the first clamp 3 and the second clamp 6 may be slid. Since the purpose of this sliding is to change the position of at least one of the first clamp 3 and the second clamp 6 along the connecting rod, the expansion / contraction function of the connecting rod 1 is used instead of sliding. Therefore, even if the distance between the first clamp 3 and the second clamp 6 can be changed along the connecting rod, the same effect can be obtained.
