Description

  The present invention relates to an infusion stand connecting device for connecting a wheelchair and an infusion stand.

  Conventionally, in order for a patient on a wheelchair to receive an infusion, the infusion stand has been moved while being held by a nurse or the like. In addition, when there is no person holding the drip stand other than the patient, the patient himself has to hold the drip stand and move it. And the movement while holding the drip stand is very dangerous.

  In recent years, a technique for connecting a wheelchair and an infusion stand has been disclosed in order to allow a patient on a wheelchair to move safely while receiving an infusion (see, for example, Patent Document 1). In Patent Document 1, a technique is described in which a rotating shaft is provided at a lower portion or a base portion of a fixed column of an infusion stand, and a joint fitting connected to a footrest of a wheelchair is provided on the rotating shaft. Furthermore, in the technique described in Patent Document 1, a pair of L-shaped movable left and right wires are provided on the joint fitting, and the left and right wires are connected to the wheelchair.

2. Next, an example of a method for connecting the drip stand 200 and the wheelchair 100 using the connecting device 1 having the above-described configuration will be described with reference to FIGS.
FIG. 5 is a perspective view showing a state in which the wheelchair 100 and the drip stand 200 are connected, and FIG. 6 is a perspective view showing a main part in the connected state.

  As shown in FIG. 5, the connecting device 1 is fixed to the drip stand 200 in advance. As a fixing method of the connecting device 1, for example, it is performed as follows. First, the support column 201 of the drip stand 200 is inserted between a pair of fixed pieces 13 a and 13 b provided on the fixed block 2. Next, the support member 201 of the drip stand 200 is fixed to the fixing unit 13 by tightening the fixing member 14.

  At this time, it is preferable to fix the connecting device 1 in the vicinity of the moving leg 202 in the support column 201. Thereby, the guide member 3 of the connecting device 1 can be brought close to the moving leg portion 202, and the guide member 3 can be prevented from being caught by another patient, a medical device, an infusion tube, or the like. Further, when the drip stand 200 and the wheelchair 100 are connected and moved, the load applied to the drip stand 200 can be set in the vicinity of the moving leg 202. Thereby, when moving, the drip stand 200 can be prevented from being out of balance and falling down.

  Next, the two sliders 6 and 6 are slid along the guide member 3 so that the distance between the two connecting arms 4 and 4 is the distance between the leg portions 103 provided in the vicinity of the footrest 101 in the wheelchair 100 to be connected. To match. Thereby, the drip stand 200 can be connected to the wheelchairs of various sizes using the single connecting device 1. Moreover, it can prevent that the connection instrument 1 hits a patient's foot | leg by making the location to connect not the footrest 101 but the leg part 103 arrange | positioned on the outer side of the footrest 101. FIG.

  Next, the two sliders 6 and 6 are rotated so that the two connecting arms 4 and 4 are directed toward the wheelchair 100. At this time, the rib piece 6 b (see FIG. 3) provided on the slider 6 contacts the rotation stop member 5. Therefore, the rotation of the slider 6 is stopped. Thereby, it can prevent that the slider 6 rotates more than necessary, and the connection member 7 provided in the front-end | tip part of the connection arm 4 can adhere to the ground, and can suppress that the connection member 7 becomes dirty. .

  The distance between the two connecting arms 4 and 4 may be adjusted after the two connecting arms 4 and 4 are directed toward the wheelchair 100.

  Next, as shown in FIG. 6, between the first clip member 31 and the second clip member 32 in the connecting member 7, specifically, between the first connecting piece 37 and the second connecting piece 38, the wheelchair 100. The leg part 103 is inserted.

  Here, a predetermined gap is formed between the front end portions of the first connection piece 37 and the second connection piece 38, and a guide surface portion 38 b is formed at the front end portion of the second connection piece 38. . Accordingly, the second clip member 32 rotates against the urging force of the urging member 42 by pressing the leg portion 103 against the guide surface portion 38 b, and the second linking piece 38 is separated from the first linking piece 37. . Furthermore, the leg portion 103 is guided between the first connecting piece 37 and the second connecting piece 38 by the guide surface portion 38b.

  When the leg 103 is inserted between the first connecting piece 37 and the second connecting piece 38, the second clip member 32 is urged by the urging member 42 and rotates. Therefore, the second connection piece 38 approaches the first connection piece 37.

  Thereby, a user such as a patient or a nurse can connect the connecting member 7 and the leg portion 103 of the wheelchair 100 without gripping the lever portion 39 and rotating the second clip member 32. . As a result, the connection work of the wheelchair 100 and the drip stand 200 can be easily performed.

That is, the leg portion 103 is locked to the locking portion 38c.

  7B, when the leg portion 103 abuts against the locking portion 38c with a stronger force, the second clip member 32 rotates together with the leg portion 103 as shown in FIG. 7C. However, the lever portion 39 of the second clip member 32 contacts the fixed grip portion 36 of the first clip member 31. Thereby, the rotation of the second clip member 32 is stopped.

At this time, a gap M through which the leg 103 can pass is formed between the tip of the first connecting piece 37 and the tip of the second connecting piece 38. However, in order for the leg portion 103 to pass through the gap M, it is necessary to once separate the leg portion 103 from the locking portion 38c. In that case, the second clip member 32 is urged by the urging member 42 (see FIG. 4), and the second connecting piece 38 rotates in a direction approaching the first connecting piece 37. Therefore, the leg portion 103 is disposed again between the first connecting piece 37 and the second connecting piece 38, and the leg portion 103 and the connecting member 7 are connected.

  Thereby, it is possible to prevent the connection between the connecting member 7 and the leg portion 103 from being disengaged due to vibrations generated when the wheelchair 100 and the drip stand 200 move. As a result, the wheelchair 100 and the drip stand 200 can be moved safely.

  Further, in order to release the connection state between the connection member 7 and the leg portion 103, a user such as a patient or a nurse operates the lever portion 39 to rotate the second clip member 32, The tip of the connecting piece 38 is separated from the tip of the first connecting piece 37. Then, the leg portion 103 is pulled out from between the first connecting piece 37 and the second connecting piece 38 with the lever portion 39 held. Thereby, the connection state of the connection member 7 and the leg part 103 can be cancelled | released, and the connection state of the wheelchair 100 and the drip stand 200 is cancelled | released.

3. Next, a method for storing the connecting device 1 having the above-described configuration will be described with reference to FIG.
FIG. 8 is a perspective view showing a state where the connecting device 1 and the wheelchair 100 are not connected.

  As shown in FIG. 8, when the drip stand 200 and the wheelchair 100 are not connected, first, the two sliders 6 and 6 are slid along the guide member 3 to approach the fixed block 2.

  Next, the slider 6 is rotated so that the connecting member 7 faces upward in the vertical direction. The slider 6 comes into contact with a stopper piece 16 provided on the fixed block 2. Further, the contact portion 6 a of the slider 6 contacts the rotation stop member 5. Thereby, the slider 6 is held at a predetermined angular position by the fixed block 2 and the rotation stop member 5.

  Further, the two connecting arms 4 and 4 are arranged in the vicinity of the column 201 of the drip stand 200. And the connecting instrument 1 can be accommodated so that the axial direction of the two connecting arms 4 and 4 is substantially parallel to the axial direction of the column 201.

  Thereby, since the two connection arms 4 and 4 do not protrude from the drip stand 200, it is possible to prevent the connection arm 4 and the connection member 7 from being caught by another patient, a medical instrument, an infusion tube, or the like.

  The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention described in the claims. In the embodiment described above, the example in which the rotation stop member 5 with which the slider 6 abuts is provided to restrict the rotation of the slider 6 has been described. However, the present invention is not limited to this, and the rotation stop member 5 is not provided. However, the object of the present invention can be achieved.

  Further, the connecting arm 4 may be configured to extend and contract along its axial direction. Thereby, it becomes possible to adjust the space | interval of an infusion stand and a wheelchair.
