Description

TECHNICAL FIELD The present invention relates to a connector for an infusion stand. More specifically, the present invention relates to a connection tool for an IV stand that connects the IV stand to a wheelchair, as well as other transportation equipment such as a rehabilitation walker or a stretcher.

In medical facilities, patients receiving intravenous drips may be moved around using mobility devices such as wheelchairs, stretchers, and rehabilitation walkers, while carrying IV stands with casters. If a patient is moved around in a wheelchair while holding an IV stand with casters, liability issues arise in the event of an accident. Furthermore, if the person pushing the wheelchair holds the IV drip stand, he or she will be pushing the wheelchair with one hand, even though he or she should be pushing the wheelchair with both hands. Therefore, in order to avoid the need for a person to hold the IV stand when moving around in a wheelchair, a connection device for an IV stand that connects an IV stand with casters to a moving device has been considered, such as Patent Document 1, Patent Document 2, A connection device for an infusion stand as disclosed in Patent Document 3 is known.

The inventors of the present application aimed to provide a versatile drip stand connector by providing a threaded clamp compatible with pipes of different sizes, in contrast to the drip stand connectors of Patent Documents 1 to 3. In addition, for the purpose of providing an IV stand that can be easily repositioned to the front, back, side, etc. of a moving device and compactly stored when not in use, the IV stand connector of Patent Document 4 was devised. The drip stand connector according to this application is sold under the trade name Photon Light, as disclosed in Non-Patent Document 1. In addition, the inventor of the present application developed the drip stand connector of Patent Document 5 for the purpose of providing a drip stand connector that can be easily repositioned by locking three rotation parts with one knob.

When the inventor of the present invention asked nurses for their opinions regarding the actual products related to the infusion stand connectors of Patent Document 4 and Patent Document 5, the following problems were found.

When attaching a clamp to an IV stand or wheelchair, you must support the connector with one hand while tightening the clamp screws, but tightening the clamp screws requires rotation, which takes time. The problem was that I had to support it with one hand. In particular, since the connector feels heavy to weak female nurses, there have been many negative reviews regarding the ability to hold the connector during installation work. In addition, many nurses were not familiar with the structure of the clamp, and the clamp installation process itself was complicated in busy workplaces, which was unpopular with nurses.
SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a connection tool for a drip stand that is even easier to attach.

In order to achieve the above object, the infusion stand connector of the present invention includes a first clamp that is detachably connected to the infusion stand and attached by tightening a screw, and a first clamp that is detachably connected to a moving device and attached by tightening the screw. A connecting device for an IV stand, comprising a second clamp for mounting, and a connecting rod portion connecting the first clamp and the second clamp, wherein at least one of the first clamp and the second clamp includes: It is characterized in that it is connected to the connecting rod part via a detachable attachment part.

As a result, when attaching a clamp that is attached by tightening screws to an IV stand or wheelchair, you can attach it by holding only the clamp that has been removed from the connecting rod, making it extremely lightweight and allowing you to leave plenty of time for inexperienced users. Able to perform work. Further, when connection with the drip stand is not required, only the clamp needs to be attached to the drip stand or wheelchair, so there is no need to reattach the clamp. These effects make it possible to eliminate the negative feedback from nurses as described in the previous issue.

In addition, by configuring the attachment/detachment part to be attached/detached by a one-touch opening/closing operation, when connecting the connecting rod part to a clamp attached to an IV stand or wheelchair, the connecting rod Even if the parts are heavy, they can be joined in a short time.
Further, since the attachment/detachment part is operated by a lever in one-touch operation, the opening/closing operation is very easy to understand and can be handled intuitively.

Moreover, the connection tool for an infusion stand of the present invention is characterized in that the connection rod part is connected to the attachment/detachment part via a free rotation part. As a result, the position of the attachment/detachment part can be adjusted by the free rotation part without being affected by the attachment position of the clamp alone, and the connection rod part and the clamp can be easily attached and detached.

More specifically, as shown in FIGS. 1, 4, and 5, the drip stand connector 100 includes a long first connecting rod 1, a short second connecting rod 2, and one end of the first connecting rod 1 A uniaxial rotating part 3 that rotatably connects one end of two connecting rods 2 on one axis, a first free rotating part 4 attached to the other end of the first connecting rod 1, and a first free rotating part 4 attached to the other end of the second connecting rod 2. a second free rotating part 5, a first clamp 6 attached to the first free rotating part 4, a second clamp 7 attached to the second free rotating part 5, a second free rotating part 5 and a second clamp 7. and a detachable part 8 for freely attaching and detaching the .

The connecting rod portion of the drip stand connector 100 of this embodiment includes the first connecting rod 1, the second connecting rod 2, the uniaxial rotating portion 3, the first free rotating portion 4, and the second free rotating portion 5. It is made up of a collection of. In addition, regarding the structure of this connecting rod part, other structures may be adopted, such as attaching a 1st free rotation part and a 2nd free rotation part to both ends of one connection rod.

Furthermore, it is assumed that the first clamp 6 of the drip stand connector 100 of this embodiment is connected to the drip stand D, and the second clamp 7 is connected to the wheelchair W, which is a moving device.
Next, each configuration of the drip stand connector 100 will be described in more detail below.

[Uniaxial rotating section 3, first free rotating section 4, second free rotating section 5]
As shown in FIG. 5, the uniaxial rotation unit 3 includes a first piece 32 and a second piece 34 held on the same axis by a hexagonal bolt 36. The first connecting rod 1 is rotatably held on the first piece 32, and the second connecting rod 2 is rotatably held on the second piece 34. Thereby, the first connecting rod 1 and the second connecting rod 2 are rotatable 360 degrees with respect to the uniaxial direction.

The second free rotating part 5 is composed of a sphere 51, a panel 52, a lid 53, and a pedestal 54. The sphere 51 is held on the panel 52, the lid 53 is screwed onto the panel 52, and the second connecting rod 2 The pedestal 54 is fixed to a rotating shaft 511 extending from the sphere 51.

The pedestal 54 can rotate 360 degrees in the rotational direction of a rotating shaft 511 extending from the sphere 51 as the sphere 51 rotates. Furthermore, as shown in the enlarged view of FIG. One cutout 58 is provided (see, eg, FIG. 1A). The pedestal 54 is configured to be able to swing along with the rotating shaft 511 up to a maximum of θ2 (approximately 100 degrees) in the direction of the notch 58.

Further, the lid 53 screwed onto the panel 52 supports the second connecting rod 2 by the second retaining ring 12 and the second fixture 13 so that it does not come off, and the position of the notch 58 of the panel 52 is , is rotatable with respect to the second connecting rod 2. Therefore, the pedestal 54 of the second free rotation section 5 can be swung by a maximum of θ2 in any direction with respect to the second connecting rod 2.
Note that the first free rotation section 4 has the same structure as the second free rotation section 5, and the pedestal 44 of the first free rotation section can also move in the same manner as the pedestal 54.

Here, as shown in the enlarged view of FIG. 5, the first piece 32 and the second piece 34 of the uniaxial rotating section 3 are brought closer to each other by rotation of the knob 35 in the locking direction (tightening direction). Then, as the first piece 32 moves in the approaching direction, the inclined surface 32a of the first piece 32 rotates, and the movement of the inclined surface 32a causes the first pressing shaft in the first connecting rod 1 to move. 46 presses the spherical body 41 of the first free rotation part 4 toward the spherical surface 42a of the panel 42. As a result, the sphere 41 cannot move, and the free rotation of the pedestal 44 of the first free rotation part 4 with respect to the first connecting rod 1 is locked. Moreover, simultaneously with the pressing of the first pressing shaft 46, the first piece 32 presses the first bearing 31 of the uniaxial rotating portion 3 as a reaction. Thereby, the rotation of the uniaxial rotating part 3 with respect to the first connecting rod 1 is also locked.

Similarly, when the first piece 32 and the second piece 34 approach each other by rotating the knob 35 in the locking direction, the inclined surface 34a of the second piece 34 also rotates, and the movement of this inclined surface 34a causes the second connection The second pressing shaft 56 in the rod 2 will press the sphere 51 of the second free rotation part 5 towards the spherical surface 52a of the panel 52. As a result, the sphere 51 cannot move, and the free rotation of the pedestal 54 of the second free rotation section 5 with respect to the second connecting rod 2 is locked. Further, at the same time as the second pressing shaft 56 presses, the second piece 34 presses the second bearing 33 of the uniaxial rotating portion 3 as a reaction. Thereby, the rotation of the uniaxial rotating part 3 with respect to the second connecting rod 2 is also locked.

In other words, in the drip stand connector 100 of the present embodiment, the first connecting rod 1 and the second connecting rod 2 constituting the connecting rod portion are rotatable 360 degrees in the uniaxial direction in the uniaxial rotating portion 3. However, by operating the knob 35 in the locking direction, the rotation of the first connecting rod 1 and the second connecting rod 2 is locked.

In addition, in the drip stand connector 100 of this embodiment, the first free rotation part 4 and the second free rotation part 5 that constitute the connection rod part can freely rotate the pedestal 44 and the pedestal 54, but the knob 35 By the operation in the locking direction, the rotations in the first free rotation section 4 and the second free rotation section 5 are locked.

Then, the drip stand connector 100 can be moved to the first pressing shaft by rotating the knob 35 in the unlocking direction from this locked state of the uniaxial rotating part 3, the first free rotating part 4, and the second free rotating part 5. 46 and the second pressing shaft 56 are released, and the uniaxial rotating section 3, the first free rotating section 4, and the second free rotating section 5 are simultaneously unlocked.

In addition, in the drip stand connecting tool 100, the first connecting rod 1 and the second connecting rod are rotatable in the uniaxial direction by the uniaxial rotating part 3 and perform link movement, so that the connection between the first clamp 6 and the second clamp 7 Distance can be changed. In addition, the first free rotation section 4 and the second free rotation section 5 allow the first clamp 6 and the second clamp 7 to rotate freely, and further swing the rotation axis of 360 degrees to θ2 (approximately 100 degrees). be able to. Therefore, since the drip stand connector 100 of this embodiment can be attached in various ways, the drip stand D can be connected to various moving devices. In addition, since it is equipped with a one-lock mechanism by operating the knob 35, it is easy to attach the IV stand connector 100, and it is possible to move the IV stand D or change the attachment position of the moving device (reclining, moving up and down, etc.). It's easy. Furthermore, even when the drip stand connector 100 is not in use, the uniaxial rotating part 3 allows it to be stored very compactly.

[First clamp 6, second clamp 7]
In this embodiment, the first clamp 6 and the second clamp 7 are common parts having the same shape. Therefore, only the second clamp 7 will be explained using the reference numeral, and the explanation of the first clamp 6 will be omitted.

As shown in FIGS. 1 to 5 and 8, the second clamp 7 has a first handshake 72 and a second handshake 73 for holding a pipe such as a handle W1 of a wheelchair W or a column D1 of an intravenous drip stand D. A frame 71 having a U-shaped cross section is rotatably supported by a first shaft 75, and a gripping screw 74 for narrowing and tightening the space between the first handshake 72 and the second handshake 73 is connected to the first handshake 72 and the second handshake 73. The second shaft 76 is rotatably supported on the distal end side of the second shaft 72 .

When fixing to a pipe, the gripping screw 74 is inserted into a notched groove 78 provided at the tip of the second handshake 73, and the gripping screw 74 is rotated in the tightening direction. On the contrary, when removing it from the pipe, the grip screw 74 is rotated and loosened, and the grip screw 74 is removed from the notch groove 78 of the second handshake 73. This operation corresponds to the clamp screw tightening operation described in the subject of the present application, and those who are not used to it are likely to feel dissatisfied with this operation.

Note that since the size of the grip between the first handshake 72 and the second handshake 73 can be changed by the gripping screw 74, the diameters of the pipes to be gripped may be different. Further, each of the first handshake 72 and the second handshake 73 is provided with a V-shaped abutment part 77, and since the pipe is gripped by the abutment part 77, the cross section of the pipe to be gripped is not necessarily circular. You can.

Since the second clamp 7 and the first clamp 6 have such a configuration, they are highly versatile for wheelchairs W and drip stands D having different pipe sizes and shapes.

[Configuration of detachable section 8]
The attachment/detachment part 8 is attached and detached by a one-touch opening/closing operation, and in this embodiment, it is an application of a so-called quick shoe structure used to connect a camera and a pan head. Specifically, as shown in FIGS. 1 to 5, the attachment/detachment part 8 includes a quick shoe clamp 81 connected to the pedestal 54 of the second free rotation part 5 on the second connecting rod 2 side, and a second clamp 7. and a quick shoe plate 82 connected to the quick shoe plate 82.

The quick shoe clamp 81 is composed of a panel 811 having side walls erected on three sides of a rectangular plate, and a detachable member 814 provided on the open side of the panel 811.

As shown in the enlarged view of FIG. 5, the quick shoe clamp 81 is fixed to the pedestal 54 of the second free rotating section 5 by screwing a panel 811 with a first screw 818. Note that the first screw 818 exposed on the bottom surface of the panel 811 is hidden by a decorative plate 812 attached to the bottom surface of the panel 811.

Further, as shown in the enlarged view of FIG. 2B, the quick shoe clamp 81 has two first engaging surfaces 813 provided at a distance on the inner side wall of the panel 811 on the side facing the detachable member 814. ing. The first engaging surface 813 provided on the inner side of the side wall of the panel 811 has a shape that slopes inward as it moves away from the bottom surface of the panel 811.

Further, the detachable member 814 has the shape of an inverted substantially trapezoidal cone, and is rotatably supported on the bottom surface of the panel 811 by a second screw 819. Further, the detachable member 814 has a second engagement surface 815 formed by an inclined side surface, and has a notch 816 formed by a substantially vertical side surface. Further, the detachable member 814 includes a lever 817 extending laterally from the side wall. This lever 817 is used to rotate the detachable member 814 when opening and closing the detachable portion 8 . Note that the lever 817 is restricted by a stopper mechanism (not shown) to rotate only between locking (position [A1] in FIG. 6A) and unlocking (position [A2] in FIG. 6A).

On the other hand, the quick shoe plate 82 is smaller than the panel 811 of the quick shoe clamp 81, and has a box-shaped engagement plate 821 (for example, see FIG. 2A) whose four sides are surrounded by low side walls, and is substantially the same as the engagement plate 821. A spacer 822 having a rectangular size.

As shown in the enlarged view of FIG. 5, the quick shoe plate 82 is fixed to the frame 71 of the second clamp 7 by screwing the engagement plate 821 with a third screw 824 with a spacer 822 in between. ing.

Further, the quick shoe plate 82 has two outer side walls of the engagement plate 821 as third engagement surfaces 823 . The two side wall outer surfaces of the engagement plate 821 constituting the third engagement surface 823 are the outer surfaces of the respective side walls facing the inclined surfaces of the first engagement surface 813 and the second engagement surface 815 in the quick shoe clamp 81. It is a side. The two third engagement surfaces 823 have a shape that slopes outward as they move away from the bottom surface of the box-shaped engagement plate 821.

In other words, the quick shoe clamp 81 and the quick shoe plate 82 that constitute the detachable part 8 have a space between the first engagement surface 813 and the second engagement surface 815 as a region into which the engagement plate 821 is fitted. In cross section, it has an isosceles trapezoid shape with the upper base on the second clamp 7 side.

[Operation of detachable section 8]
The main operations of the attachment/detachment tool 8 will be explained using the drawings. FIG. 1B is a perspective view showing the rotation direction of the lever 817, FIGS. 2A and 2B are perspective views showing the quick shoe clamp 81 and the quick shoe plate 82 separated, and FIG. 3B is a perspective view showing the quick shoe clamp 81 and the quick shoe plate 82. This is an image of a prototype showing a state in which the shoe plate 82 is separated. FIG. 6A is a plan view of the quick show clamp 81 showing the change between locking and unlocking of the attachment/detachment part 8, where [A1] shows the locked state and [A2] shows the unlocked state. FIG. 6B is a VIB-VIB sectional view of A with the quick shoe plate 82 added, in which [B1] shows the locked state and [B2] shows the unlocked state.

As shown in [A1] of FIG. 6A, when the lever 817 on the side of the quick shoe clamp 81 is in the "closed" position, as shown in [B1] of FIG. 6B, the first engaging surface 817 of the panel 811 and one third engagement surface 823 of the engagement plate 821 on the quick shoe plate 82 side are in contact with each other, and the second engagement surface 815 of the detachable member 814 and the other third engagement surface 823 of the engagement plate 821 on the quick shoe plate 82 side are in contact with each other. Since the quick shoe plate 82 is in contact with and engaged with the third engagement surface 823, the quick shoe plate 82 is in an attached state held by the quick shoe clamp 81. Since this holding is performed by the inclined surface of an isosceles trapezoid when the second clamp 7 side is the upper base, it is very strong.

Further, as shown in [A2] of FIG. 6A, when the lever 817 on the quick shoe clamp 81 side is in the "open" position, the notch 816 also rotates and changes its position as the lever 817 rotates. At this time, the notch 816 is in a position facing the third engagement surface 823, and as shown in [B2] in FIG. 6B, the notch 816 of the detachable member 814 and the third engagement surface 823 A gap L1 is created between the surface 823 and the surface 823. Therefore, the quick shoe plate 82 is released from the quick shoe clamp 81. In addition, in the drip stand connector 100 of the present embodiment, the gap L1 at this time is equal to 2 of the dimension of the panel 811 in the engaged state on the first engagement surface 813 side (L2 in [B2] in FIG. 6B). It is set to be more than double.

In this manner, the drip stand connector 100 of the present embodiment allows the second clamp 7 to which the quick shoe plate 82 is attached to be connected to the quick shoe clamp 81 by operating the lever 817 of the detachable member 814 in the detachable portion 8. It is configured such that it can be attached and detached from the pedestal 54 of the second free rotation section 5 to which is attached.

[Another example of detachable part 8]
Although the drip stand connector 100 of the present embodiment uses a lever 817 of the detachable member 814 as the attachable/detachable part 8 that can be attached and detached by a one-touch opening/closing operation, other configurations may also be adopted. . In addition to operating the lever 817, a one-touch opening/closing operation can be performed. Specifically, for example, a button-type attachment/detachment part that can be attached and detached by an opening/closing operation consisting of an engaging claw moving in and out in conjunction with pressing the button may be adopted. can.

Further, it is also possible to adopt a configuration of the attachment/detachment section 8 that is not limited to one-touch opening/closing operation. This specific example will be explained using figures. FIG. 7A is a diagram showing a second clamp 7 portion of an IV stand connector 100A with a detachable part 8A attached thereto as another example, and FIG. 7B is a diagram showing a state in which the detachable part 8A of FIG. 7A is separated. .

The attachment/detachment section 8A differs from the attachment/detachment section 8 in that a screw-type knob 817A is used in place of the lever 817. Specifically, the first engagement surface 813A and the second engagement surface 815A of the quick shoe clamp 81A engage with the two third engagement surfaces 823A of the quick shoe plate 82A, and by operating the screw-type knob 817A, , the second engagement surface 815A of the detachable member 814A moves to attach and detach. Such a configuration requires a little more time than the one-touch opening/closing operation of the lever 817 in the attachment/detachment section 8 because it is necessary to rotate the screw-type knob 817A. On the other hand, in the lever 817 of the attachment/detachment part 8, the second engagement surface 815 only contacts a part of the third engagement surface 823 (on the second engagement surface 815 side) as shown in FIG. 6A. In the screw-type knob 817A of the attachment/detachment portion 8A, the second engagement surface 815A comes into contact with the entire third engagement surface 823A (on the second engagement surface 815A side). Therefore, in the attachment/detachment portion 8A, the quick shoe clamp 81A and the quick shoe plate 82A can be maintained in a more firmly attached state.

[Usage example (wheelchair)]
Next, with reference to FIG. 8, connection of a wheelchair W will be described as an example of use of the drip stand connection tool 100 of this embodiment. FIG. 8A is a perspective view showing a state in which the wheelchair W and the drip stand D are not connected, and FIG. 8B is a perspective view showing a state in which the wheelchair W and the drip stand D are connected.

The connection between the wheelchair W and the drip stand D using the drip stand connector 100 of this embodiment is achieved by a second free rotation of the second clamp 7 and the connecting rod portion at the detachable portion 8 of the drip stand connector 100. This is done by attaching and detaching the part 5.

That is, instead of attaching and detaching the wheelchair W and the drip stand connector 100 by attaching and detaching the second clamp 7 and the handle W1 of the wheelchair W as in Patent Document 5, the second clamp 7 is attached to the handle W1 of the wheelchair W. This is done by attaching and detaching using the attachment/detachment section 8 while leaving it attached to W1.

Therefore, when attaching the IV stand connector 100 to the wheelchair W, there is no need to work while supporting the IV stand connector 100 itself (the connecting rod part and the first clamp 6), and it is not necessary to work while supporting the IV stand connector 100 itself. Since only the separated second clamp 7 can be held and attached to the handle W1 of the wheelchair W, the work of attaching the second clamp 7 can be easily performed.

To attach the second clamp 7 to the handle W of the wheelchair W, first rotate the lever 817 of the attachment/detachment part 8 to remove the second clamp 7 from the second connecting rod 2. Then, the handle W1 of the wheelchair W is held between the first handshake 72 and the second handshake 73 of the second clamp 7 that has been removed, the gripping screw 74 is inserted into the notched groove 78, and the gripping screw 74 is tightened.

Further, the second clamp 7 and the connecting rod part of the drip stand connector 100 can be attached and detached by opening and closing the second clamp 7 to which the quick shoe plate 82 is attached by operating the lever 817 of the detachable member 814 in the detachable part 8. Since this can be done by attaching and detaching the second connecting rod 2 to which the quick shoe clamp 81 is attached, it is possible to very easily attach the drip stand coupler 100 to the wheelchair W.

The connection between the second clamp 7 and the connecting rod part of the drip stand connector 100 is achieved by engaging the quick shoe clamp 81 on the second connecting rod 2 side with the quick shoe plate 82 on the second clamp 7 side, and then using the lever. This is done by rotating 817.

In addition, when it is not necessary to connect the wheelchair W and the drip stand D, the second clamp 7 is left attached to the handle W1 of the wheelchair W, and the connecting rod portion of the second clamp 7 and the drip stand connector 100 is Since they can be separated from each other, the operation of removing the drip stand connector 100 from the wheelchair W can be performed very easily.

The second clamp 7 and the connecting rod part of the drip stand connector 100 can be separated by rotating the lever 817, which separates the quick shoe clamp 81 on the second connecting rod 2 side and the quick shoe plate on the second clamp 7 side. This is done by releasing the engagement with 82.

The effect of using the infusion stand connector 100 of this embodiment is that even a nurse who is not familiar with the structure of the second clamp 7 can easily attach the second clamp 7. Therefore, this is very preferable, and once the second clamp 7 is attached to the wheelchair W, there is no need to attach or remove the second clamp 7 each time, which is very preferable in busy medical settings.

In the usage example shown in FIG. 8, the second clamp 7 is attached to the handle W1 of the wheelchair W, but it may be attached to a pipe other than the handle W1 of the wheelchair W. In particular, the drip stand connector 100 of this embodiment has the first free rotation part 4 and the second free rotation part 5 on the connecting rod, so the second clamp 7 can be attached to various positions of the wheelchair W. However, since the position of the quick shoe clamp 81 can be freely adjusted according to that position, it is possible to stably connect it to the drip stand D.

Further, the drip stand connector 100 can be used not only for a wheelchair W as shown in FIG. 8, but also for transportation devices such as a stretcher and a rehabilitation walker. And, since the connection rod part of the drip stand connector 100 is equipped with the first free rotation part 4 and the second free rotation part 5, the drip stand can be used stably even when moving devices other than the wheelchair W. Concatenation can be performed with D.

Further, in the usage example shown in FIG. 8, the second clamp 7 equipped with the detachable part 8 was attached to the handle W1 of the wheelchair W, but in this embodiment, the second clamp 7 is attached to the column D1 of the drip stand D. It is also possible to use the connection tool 100 for an infusion stand. However, since not only an infusion bag but also various devices may be attached to the drip stand, it is often necessary to change the attachment position of the second clamp 7 from time to time. Therefore, unlike the wheelchair W in the usage example, even if the second clamp 7 is left attached to the drip stand D, the position of the second clamp 7 may be changed during use. Therefore, in the case of the drip stand connector 100 as in this embodiment, it is better to use the second clamp 7 provided with the attachment/detachment part 8 for the wheelchair W.

In this regard, although the drip stand connector 100 has a configuration in which the attachment/detachment part 8 is provided only on the second clamp 7 side, it is possible to adopt a configuration in which the first clamp 6 side is also provided with a similar attachment/detachment part. You can also do it. In this way, both the first clamp 6 and the second clamp 7 are connected to the connecting rod part through the detachable part, so that the first clamp 6 and the second clamp 7 are connected to the wheelchair W and the drip stand D, respectively. can be left attached, and the position of only the first clamp 6 (or second clamp 7) can be changed as appropriate on the drip stand D side. Of course, such a configuration is preferable since problems such as those described in the subject of the present application also occur in the work of attaching the first clamp 6 on the drip stand D side as well.

In addition, in the drip stand connector 100 of the embodiment, there is only one second clamp 7 to which the quick shoe plate 82 is attached, but a plurality of second clamps 7 to which the quick shoe plate 82 is attached are prepared. Alternatively, the second clamps 7 may be attached to different wheelchairs W. In this case, one connecting rod portion of the drip stand connecting tool 100 can be reused. Such usage does not always require connection between the wheelchair W and the drip stand D, and is very convenient in a hospital where a plurality of wheelchairs W are used. In commercializing the product, it is assumed that a plurality of second clamps 7 will be prepared and sold.

In addition, in the drip stand connector 100 of the embodiment, the first connecting rod 1 having a long connecting rod portion and the short second connecting rod 2 are used. You can configure it. Such a configuration also reduces costs by standardizing parts. Further, the connecting rod portion was configured using a uniaxial rotating portion 3 that rotatably connects one end of the first connecting rod 1 and one end of the second connecting rod 2 around one axis, but the uniaxial rotating portion 3 is Instead, it may be configured with a single connecting rod. Such a configuration also reduces costs by reducing the number of parts.
