For example, JP 2017-104591 A discloses a medical rack capable of mounting a syringe pump. The rack has a main body capable of mounting a syringe pump and a pole clamp fixed to the main body. The main body is removably fixed to the pole using the pole clamp.

JP 2017-104591 A

In the rack described in JP 2017-104591 A, when a syringe pump is attached to the rack, in order to remove air bubbles from the syringe, it is necessary to remove the syringe pump from the rack or to remove the syringe from the syringe pump.

On the other hand, there is a need to be able to change the mounting position of a device, such as a syringe pump, on a pole while the device remains attached to the pole.

The object of the present invention is to provide a clamp structure and a syringe pump unit that allow the mounting position of the device on the pole to be changed.

A clamp structure according to one aspect of the present invention includes a clamp that can be attached to a pole, and a fixing member that can be connected to a device and fixed to the clamp, the clamp has a clamp portion that can tighten the pole, and a holding portion that is connected to the clamp portion and can hold the fixing member, the fixing member has a base that can be connected to the device, and a held portion that is connected to the base and can be held by the holding portion, the held portion can be held by the holding portion in a first position where the device is in a first position relative to the pole, and in a second position where the device is in a second position relative to the pole.

In this clamp structure, the position of the device relative to the pole is changed by changing the position at which the held part is held by the holding part. This makes it possible to change the mounting position of the device relative to the pole while the device remains attached to the pole.

The holding portion is connected to the clamp portion and has a base formed in a disk shape including a plane parallel to the longitudinal direction of the pole, and a plurality of protruding portions each arranged at intervals in the circumferential direction of the base and having a shape that protrudes outward from the edge of the base in the radial direction of the base, and the held portion has a plurality of held pieces arranged at intervals in the same direction as the direction in which the plurality of protruding portions are arranged, and each holding piece of the plurality of held pieces preferably has a standing portion having a shape that rises from the base, and a clamping portion connected to the tip of the standing portion and clamping the protruding portion together with the base in the thickness direction of the base.

It is also preferable that the fixing member is connectable to a syringe pump as the device, the first position is a position of the syringe attached to the syringe pump when in use, and the second position is a position in which the tip of the syringe faces upward more than the position when in use.

In this embodiment, with the syringe pump attached to the pole by the clamp, the holding part holds the held part in the second position before using the syringe pump, thereby removing air bubbles from within the syringe, and thereafter, the holding part holds the held part in the first position, thereby enabling the syringe to be used.

In this way, with this clamp structure, it is possible to easily remove air bubbles from inside the syringe when the syringe pump is attached to the pole.

A syringe pump unit according to one aspect of the present invention includes the clamp structure and a syringe pump fixed to the fixing member of the clamp structure.

The present invention provides a clamp structure and a syringe pump unit that allow the mounting position of the device on the pole to be changed.

The embodiment of the present invention will be described with reference to the drawings. Note that in the drawings referred to below, the same or equivalent components are given the same numbers.

Figure 1 is a perspective view showing a syringe pump unit according to one embodiment of the present invention fixed to a pole. Figure 2 is a perspective view showing a syringe pump unit with a fixing member held in a second position by a clamp.

As shown in Figures 1 and 2, the syringe pump unit 1 is attached to a pole 2. The syringe pump unit 1 includes a syringe pump 5 as a device and a clamp structure 10.

A syringe (not shown) is attached to the syringe pump 5. The syringe pump 5 is capable of driving the syringe.

The clamp structure 10 is a structure that fixes the syringe pump 5 to the pole 2. The clamp structure 10 has a clamp 100 and a fixing member 200.

The clamp 100 can be attached to the pole 2. The clamp 100 has a clamp portion 110 and a holding portion 120.

The clamp unit 110 is capable of clamping the pole 2. The clamp unit 110 has a clamp body 112 and a handle 114.

As shown in Figures 3 and 4, the clamp body 112 has a pair of clamping parts 112a that clamp the pole 2 and a connecting part 112b that connects the pair of clamping parts 112a.

The handle 114 is attached to one of the clamping parts 112a of the clamp body 112. The clamping force for the pole 2 is adjusted by operating the handle 114.

The holding portion 120 is connected to the clamp portion 110 and is capable of holding the fixing member 200. The holding portion 120 has a base portion 122, a plurality of (four in this embodiment) protrusions 124, a moderation member 126, and a biasing member 128.

The base 122 is formed in a plate shape including a plane parallel to the connecting portion 112b (a plane parallel to the longitudinal direction of the pole 2). In this embodiment, the base 122 is formed in a disk shape. As shown in FIG. 5, the base 122 is provided with a through hole 122h.

The multiple protrusions 124 are connected to the edge of the base 122. The multiple protrusions 124 are arranged at intervals in the circumferential direction of the base 122. Specifically, the multiple protrusions 124 are arranged at equal intervals in the circumferential direction of the base 122. Each protrusion 124 has a shape that protrudes outward from the edge of the base 122 in the radial direction of the base 122.

The moderation member 126 is attached to the base 122. The moderation member 126 has a cylindrical portion 126a and a moderation portion 126b.

The tubular portion 126a is formed in a cylindrical shape. The tubular portion 126a is disposed between the clamp body 112 and the base portion 122. The outer diameter of the tubular portion 126a is larger than the outer diameter of the through hole 122h. This prevents the moderation member 126 from coming off between the clamp body 112 and the base portion 122.

The moderation portion 126b is connected to the end of the cylindrical portion 126a. The moderation portion 126b is disposed within the through hole 122h. The moderation portion 126b is formed solid. The tip of the moderation portion 126b protrudes from the base portion 122 in a direction away from the clamp body 112. The tip of the moderation portion 126b has a curved shape that is convex in a direction away from the cylindrical portion 126a.

The biasing member 128 biases the moderation member 126 in a direction away from the clamp body 112. The biasing member 128 is disposed between the moderation member 126 and the clamp body 112. Specifically, the biasing member 128 is disposed within the cylindrical portion 126a. The moderation member 126 is movable in the axial direction of the cylindrical portion 126a against the biasing force of the biasing member 128.

The fixing member 200 can be connected to a syringe pump 5 as a device, and can be fixed to the clamp 100. The fixing member 200 has a base 210 and a held portion 220.

The base 210 can be connected to the syringe pump 5. The base 210 is formed in a flat plate shape. As shown in Figs. 3 and 6, the base 210 is provided with recesses 210a that engage with the moderation portion 126b. In this embodiment, the base 210 is provided with four recesses 210a at equal intervals.

The held portion 220 is connected to the base 210. The held portion 220 can be held by the holding portion 120. Specifically, the held portion 220 can be held by the holding portion 120 at a first position (the position shown in FIG. 1) and a second position (the position shown in FIG. 2).

The first position is a position where the device is in a first position relative to the pole 2. In this embodiment, the first position is the position of the syringe attached to the syringe pump 5 when in use.

The second position is a position in which the device is in a second position relative to the pole 2. In this embodiment, the second position is a position in which the tip of the syringe is more upwardly oriented than in the position during use.

3 and 6, the held portion 220 has a plurality of held pieces 222 (four in this embodiment). The plurality of held pieces 222 are spaced apart in the same direction as the direction in which the plurality of protruding portions 124 are arranged (the circumferential direction of the base portion 122). Specifically, the plurality of held pieces 222 are spaced apart in the same direction. Each held piece 222 is formed outside the circle connecting the four recesses 210a. Specifically, each held piece 222 is formed outside the recess 210a on the straight line connecting the center of the circle and the recess 210a. Each held piece 222 has an upright portion 222a and a clamping portion 222b.

The standing portion 222a has a shape that rises from the base 210. The clamping portion 222b is connected to the tip of the standing portion 222a and has a shape that clamps the protruding portion 124 together with the base 210 in the thickness direction of the base 210. The clamping portion 222b has a shape that protrudes inward from the tip of the standing portion 222a.

Next, we will explain how to use the syringe pump unit 1 described above.

First, the clamp 100 is fixed to the pole 2 at the desired height by operating the handle 114, and the syringe pump 5 is connected to the fixing member 200.

Then, the retained portion 220 of the fixed member 200 is retained by the retaining portion 120 of the clamp 100. Specifically, the retaining portion 120 is pressed against the base 210 so that each protrusion 124 is positioned between adjacent retained pieces 222, and then the syringe pump 5 and the fixed member 200 are rotated relative to the clamp 100. This causes the retained portion 220 and the retaining portion 120 to engage with each other. In other words, each protrusion 124 is positioned between the base 210 and the clamping portion 222b. At this time, the moderation member 126 engages with the recess 210a, so that the user feels a sense of moderation.

Next, the syringe pump 5 and the fixing member 200 are rotated relative to the clamp 100 so that the held portion 220 is held in the second position by the holding portion 120. At this time, the moderation member 126 disengages from the recess 210a against the biasing force of the biasing member 128 and slides on the surface of the base 210. When the held portion 220 is held by the holding portion 120 in the second position, the moderation member 126 engages with the recess 210a. This conveys a sense of moderation to the user. As a result, the air bubbles in the syringe move to the tip of the syringe.

After the operation to remove air bubbles from the syringe is completed, the syringe pump 5 and the fixing member 200 are rotated relative to the clamp 100 so that the holding portion 220 is held in the first position by the holding portion 120. When the holding portion 220 is held by the holding portion 120 in the first position, the moderation member 126 engages with the recess 210a. This conveys a sense of moderation to the user.

As described above, in the clamp structure 10 of this embodiment, the attitude of the syringe relative to the pole 2 is changed by changing the position at which the held portion 220 is held by the holding portion 120. Therefore, when the syringe pump 5 is attached to the pole 2 by the clamp 100, the holding portion 120 holds the held portion 220 in the second position before using the syringe pump 5, thereby removing air bubbles from within the syringe, and thereafter, the holding portion 120 holds the held portion 220 in the first position, thereby making it possible to use the syringe.

Therefore, when the syringe pump 5 is attached to the pole 2, it is not necessary to remove the syringe pump 5 from the clamp 100 or to detach the syringe from the syringe pump 5 in order to remove air bubbles from the syringe.

The fixing member 200 can rotate 360 degrees relative to the holding part 120, and the held part 220 can be held by the holding part 120 in four positions including a first position and a second position. Therefore, for example, if the device contains a drug, it is possible to mix the drug while the device is attached to the pole 2 by rotating the device and the fixing member 200 relative to the clamp 100.

It should be noted that the embodiments disclosed herein are illustrative in all respects and should not be considered limiting. The scope of the present invention is indicated by the claims rather than the description of the embodiments above, and further includes all modifications within the meaning and scope of the claims.

The shapes of the holding portion 120 and the held portion 220 can be changed as appropriate. For example, the holding portion 120 may have a standing portion that rises from the base portion 122 and a protruding portion that protrudes inward or outward from the tip of the standing portion, and the held portion 220 may be formed into a shape that holds the protruding portion.
