Description

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

Patients in a drip infusion may move in a wheelchair in a medical facility. Liability issues arise when an accident occurs when a patient holds a drip stand with casters and moves in a wheelchair. Further, when a person who pushes a wheelchair grips the drip stand, he or she should push the wheelchair with one hand, although he or she should push the wheelchair with both hands. Therefore, a drip stand connector for connecting a drip stand with casters to a moving device is conceivable so that a person does not have to hold the drip stand when moving in a wheelchair.

In the conventional drip stand connector, there are various positions of the drip stand with casters with respect to the wheelchair, such as a front part, a rear part, and a side part. Patent Document 1 is an example of the front part, Patent Document 2 is an example of the rear part, and Patent Document 3 is an example of the side part.

By the way, when moving in a narrow corridor, a place with a lot of people, or when moving through a narrow frontage, it is better to position the drip stand before and after the wheelchair. Also, in elevators and toilets with a short depth, the position of the drip stand should be on the side of the wheelchair.

However, the drip stand connector of Patent Documents 1 and 2 cannot move the position between the front and rear and side portions of the wheelchair or the rear and side portions. Paragraph No. 0032 describes that the connector for the drip stand of Patent Document 3 bends a flexible flexible shaft to reduce the distance between the connector for the drip stand and the wheelchair. There is no description of moving the position between the side part or the rear part and the side part.

On the other hand, the drip stand connector of Non-Patent Document 1 is provided with a rotating part for rotating the drip stand with respect to the wheelchair, and the drip stand connector moves between the rear part and the side part of the wheelchair.

However, the method of attaching to a wheelchair in Non-Patent Document 1 is to attach both ends of a long support pillar that supports a rotating portion to a handle above the wheelchair and a horizontal frame below the wheelchair. For this reason, the drip stand connector is large. Also, since a long strut to be attached to a wheelchair is required, if it is to be attached to another wheelchair, it is necessary to remove this strut and attach it to another wheelchair, or prepare this strut for another wheelchair, It is extremely inconvenient to use in hospitals (note that the pamphlet states that the user cannot switch to another wheelchair).

Further, the rotating portion is an axial rotation that slides on the cylindrical surface. Therefore, the drip stand cannot smoothly rotate along the floor surface unless its rotation axis is perpendicular to the floor surface. However, the handlebars of a general wheelchair are usually inclined, and the inclination angles of the handlebars are not standardized, so the handlebar and the lower horizontal frame are not parallel. However, it is not easy to vertically attach the rotating shaft of the rotating portion, and the supporting column for mounting has a complicated structure.

Further, since the position and shape of the lower horizontal frame are various, there are wheelchairs that cannot be attached to the handle and the lower horizontal frame because the positions of the lower horizontal frames do not match. Furthermore, some wheelchairs do not have this horizontal frame below.

Further, if the drip stand connector can be stored on the drip stand side, it is easy to use the drip stand connector for other wheelchairs, stretchers, etc., but the drip stand connector of Non-Patent Document 1 Cannot be stored on the IV stand side.

Therefore, an object of the present invention is to provide a small-sized drip stand connector and a connecting aid which are capable of moving the drip stand connector to the rear and side portions of the moving device and which can be easily attached. ..

In order to achieve the above object, the drip stand connector of the present invention includes a first clamp detachably connected to the drip stand, a second clamp detachably connectable to a transfer device, and the first clamp. Is a connecting rod for holding the second clamp on one end side and the second clamp on the other end side, wherein the second clamp is a sphere that rotates in a free direction and a uniaxial Is rotatably held by the connecting rod via a second rotating portion composed of a uniaxial rotating body that rotates and rotates, the first clamp is connected to the drip stand, and the second clamp is for moving. The drip stand can be rotated by the second rotating portion while being connected to an instrument.

As a result, the first clamp can be rotated by the second rotating portion composed of the spherical body that rotates in the free direction and the uniaxial rotating body that rotates and rotates about one axis, so that the drip stand can be placed around the moving device. Can be moved. For example, it is quick and easy to move the drip stand to the back of the wheelchair in a narrow corridor and to the side of the wheelchair in an elevator with a short depth. In addition, since the second rotating portion can perform free rotation by the spherical body and rotation by the uniaxial rotating body, even when the connecting rod is inclined, the drip stand is moved when the position of the drip stand is moved. The stand is stable.

In addition, in the drip stand connector of the present invention, the first clamp includes the connecting rod via a first rotating portion including a spherical body that rotates in a free direction and a uniaxial rotating body that rotates and rotates about one axis. It is characterized by being retained in.

With this, since the height and the direction of the first clamp and the second clamp can be changed, the drip stand connector can be applied to various types of moving devices including a wheelchair. Further, during storage, the second clamp is removed from the moving device, and the connecting rod is rotated to hold the second clamp on the drip stand, whereby the connector can be stored in the drip stand. Further, for example, even when passing through an inclined corridor in a hospital, the state of the drip stand can be made to follow the inclination by the first rotating portion, and the drip stand can be stabilized.

In addition, in the drip stand connector of the present invention, the first rotating portion and the second rotating portion perform a switching operation between locking and unlocking the free rotation of the spherical body and the uniaxial rotation of the uniaxial rotation body. It is characterized by having a lock knob to be performed at the same time.

When changing the height and the direction of the first clamp and the second clamp, the lock knob is operated to lock or unlock the free rotation and the uniaxial rotation of the first rotating portion and the second rotating portion. Therefore, it is easy to attach and move the drip stand to the moving device. Since the first rotating portion and the second rotating portion each have a lock knob, the operation for locking and unlocking the lock is easy, and the operation can be performed within the field of view of the patient.
Further, the drip stand connector of the present invention is characterized in that the second clamp is attached to a handle of the transfer device which is a wheelchair.

As a result, since the wheelchair is equipped with a handle, the user can easily understand the mounting position, and a plurality of users can operate the mounting position in a unified manner. In addition, for example, when operating the lock knob of the second rotating portion, the operation can be performed with the patient in the visual field range, so that the operation of rotating the drip stand can be performed with caution.

Further, the drip stand connector of the present invention is characterized in that the second clamp is attached to the second rotating portion via an L-shaped attachment fitting that changes an attachment angle at a right angle.

This makes it easy to avoid contact between the brake and the second clamp under the wheelchair handle. In addition, the main rotation operation when the drip stand is rotationally moved to the side surface or the rear of the wheelchair can be performed by the uniaxial rotation by the uniaxial rotation body of the second rotation unit, and the main rotation operation can be freely performed by the sphere. The user can smoothly rotate the drip stand as compared with the case of moving the drip stand. Note that this point is based on the verification result by the inventor.

In addition, the connecting auxiliary tool of the present invention is characterized in that it is used when connecting the drip stand and the moving device composed of a stretcher by using the drip stand connecting tool of the present invention. Accordingly, even with a stretcher that is difficult to connect with the second clamp, the drip stand and the stretcher can be connected using the drip stand connector of the present invention. In addition, the auxiliary tool for connection is specifically, fixed and used for the drip stand attachment part originally provided in the stretcher.

Further, the auxiliary connecting tool of the present invention is characterized by comprising a fixed shaft portion and a mounting shaft portion orthogonal to the fixed shaft portion. This allows the mounting shaft portion to be directed to the outside of the stretcher, and thus the drip stand connection portion can be separated from the patient carried by the stretcher.

It is not displayed in proportion to the size of.

[Embodiment 1]
A configuration of a main part of the drip stand connector 100 according to the embodiment will be described with reference to FIGS. 1 to 4. FIG. 1 is a front view of a drip stand connector 100. FIG. 2 is a plan view thereof. FIG. 3 is a side view thereof. 4A is a sectional view of the first rotating portion passing through the lock knob 26, and FIG. 4B is a sectional view perpendicular to FIG. 4A. In addition, the drip stand connector 100 of the present embodiment connects the drip stand D with casters to the wheelchair W, which is a moving device.

As shown in FIGS. 1 and 2, a drip stand connector 100 includes a connecting rod 1, a first rotating portion 2 and a first clamp 3 which are sequentially attached to one end of the connecting rod 1, and another connecting rod 1. It is composed of a second rotating portion 4, an L-shaped attachment 5, and a second clamp 6 which are sequentially attached to the end side. The material of these components consists mainly of surface-treated aluminum or acrylic. The connecting rod 1 is a rod having a diameter of 24 mm and a length of 250 mm.

The first rotating portion 2 is composed of a spherical body 22 that rotates freely in up, down, left, and right directions, and a uniaxial rotating body 25 that rotates about one axis. More specifically, as shown in FIG. 4, the first rotating portion 2 includes a panel 21, a spherical body 22, a pedestal 23, a connecting screw 24, a uniaxial rotating body 25, a lock knob 26, and a detachment. It consists of a stop pin 27 and a component plate 28.

The panel 21 is composed of an upper hemispherical portion 211 and a lower cylindrical portion 212 in FIG. The hemispherical portion 211 accommodates the sphere 22 and the cylindrical portion 212 accommodates the uniaxial rotating body 25. The tip of the hemispherical portion 211 of the panel 21 is open, and the connection boss 221 of the sphere 22 is exposed from here.
Then, the spherical surface 222 of the spherical body 22 comes into contact with the inner surface 211a of the hemispherical portion 211 and slides on the shaft in the free direction, so that the spherical body 22 can freely rotate.

Further, the pedestal 23 is fixed to the exposed boss 221 by the connecting screw 24, and the male screw 241 of the connecting screw 24 is exposed from the pedestal 23, so that the connecting rod 1 is connected.

The uniaxial rotating body 25 includes a sliding portion 251 and a lid portion 252. The sliding portion 251 is housed in the cylindrical portion 212 of the panel 21, is in contact with the inner surface 212a of the cylindrical portion 212, and can slide up and down, and can rotate 360 degrees on one axis. ..

A pressing surface 253, which is a concave spherical surface, is formed on the sliding portion 251, so that the pressing surface 253 presses the spherical surface 222 of the spherical body 22 upward as the sliding portion 251 slides upward. It has become. In addition, a groove 254 is formed below the sliding portion 251, and the retaining pin 27 inserted from below the side surface of the cylindrical portion 212 of the panel 21 is fitted into the groove 254, whereby the uniaxial rotating body 25 Does not come off from the panel 21.

The lid portion 252 closes the lower side of the cylindrical portion 212 of the panel 21, and has a connecting female screw 255 formed in the center. Then, the connection with the first clamp 3 is performed by the connecting female screw 225.

The lock knob 26 includes a shaft 261 formed with a male screw. The tip of this shaft 261 is a conical surface 262. Then, the conical surface 262 of the shaft 261 enters the inside of the panel 21 from the penetrating female screw 213 provided on the side surface of the cylindrical portion 212 of the panel 21. Then, in order to avoid contact with the shaft 261, an empty portion 256 is formed in the sliding portion 251 of the uniaxial rotating body 25, and the upper portion of this empty portion 256 is an inclined component force surface 257. There is.
Further, a force dividing plate 28 is disposed so as to be inclined between the force dividing surface 257 of the uniaxial rotating body 25 and the conical surface 262 of the lock knob 26.

With this configuration, when the conical surface 262 of the lock knob 26 is screwed inward in the panel 21 in FIG. 4A, the uniaxial rotary body 25 slides upward due to the component force via the component force plate 28. It will be done. At this time, the sphere 22 is pressed upward by the pressing surface 253. As a result, the uniaxial rotating body 25 and the sphere 22 are sandwiched between the inner surface 211a of the hemispherical portion 211 of the panel 21 and the shaft 261 of the lock knob 26, so that the sphere 22 can freely rotate and the uniaxial rotating body 25 can rotate. The shaft rotation is locked by the lock knob 26.

As described above, in the first rotating portion 2, the free rotation of the spherical body 22 and the uniaxial rotation of the uniaxial rotating body 25 can perform the lock and unlock operations by the single lock knob 26.

Further, as shown in FIG. 4A, the tip end of the hemispherical portion 211 of the panel 21 opens larger than the size of the connecting boss 221 of the spherical body 22. Therefore, the pedestal 23 can swing the rotation axis of the sphere 22 by θ1 (about 25 degrees) to the left and right.

Further, as shown in FIGS. 1 and 4B, a groove 214 which is a notch for avoiding contact of the connection boss 221 is formed in the upper portion of the panel 21. Therefore, the pedestal 23 can swing the rotation axis of the sphere 22 by θ2 (about 90 degrees) to the left and right.

The spherical body 22 that rotates in the free direction in the first rotating unit 2 of the present embodiment is similar to a so-called free pan (or 3D pan or the like), and rotates about one axis. The moving uniaxial rotating body 25 is the same as the rotating body provided with a rotation axis in the lateral direction separately from the rotation of the sphere in the free platform.

Further, in the present embodiment, the second rotating portion 4 is a common component having the same shape as the first rotating portion 2. Specifically, the second rotating portion 4 includes a spherical body 42 that rotates in a free direction and a uniaxial rotating body 45 that rotates and rotates about one axis. The other specific configuration is the same as that of the first rotating unit 2, and thus the description thereof is omitted. The sphere 22 of the first rotating portion 2 is fixed to one end of the connecting rod 1, and the sphere 42 of the second rotating portion 4 is fixed to the other end of the connecting rod 1.

Next, the first clamp 3 includes a frame 31, a first handshake 33, a second handshake 34, and a grip screw 36. The frame 31 has a "U" shape (a shape close to a U shape) fixed to the uniaxial rotating body 25 of the first rotating portion 2. Further, the first handshake 33 and the second handshake 34 are rotatably supported at their one ends by two first shafts 32 penetrating opposite sides of the frame 31. The grip screw 36 is rotatably supported by the second shaft 35 on the other end of the first handshake 33.

Here, the first handshake 33 and the second handshake 34 rotate and grip the vertical column D1 of the drip stand D by gripping it, and the V-shaped contact parts of acrylic are provided at the sandwiched parts. 37 are provided. The contact portion 37 is made of a resin such as synthetic resin acrylic so that the support D1 of the drip stand D is less likely to be damaged.

Then, with the support D1 of the drip stand D sandwiched between the first handshake 33 and the second handshake 34, the gripping screw 36 pivotally supported by the first handshake 33 is fitted into the notch groove 38 of the second handshake 34. To be done. Then, the gripping screw 36 is screwed in at a position where it comes into contact with the stopper 39 provided on the second handshake 34. As a result, the distance between the first handshake 33 and the second handshake 34 in the sandwiched state is grasped and the screw 36 is contracted to firmly fix the first clamp 3 to the drip stand D.

Since the size of the first handshake 33 and the second handshake 34 can be changed by the grip screw 36, the diameter of the gripped pipe may be different. Further, since the two V-shaped contact portions 37 are sandwiched and gripped, the cross section of the gripped pipe does not necessarily have to be circular. Further, the shape of the first clamp 3 is not limited to the present embodiment as a matter of course, and may be any other shape as long as it can be detachably connected to the column D1 of the drip stand D.

In addition, in the present embodiment, the second clamp 6 is a common component having the same shape as the first clamp 3, and the description of the specific configuration will be omitted. The second clamp 6 is connected to the second rotating portion 4 via the L-shaped attachment 5.

The L-shaped attachment 5 is for connecting the second clamp 6 to the second rotating portion 4 by changing the attachment angle of the second clamp 6 to a right angle. As shown in FIGS. 1 and 2, the L-shaped attachment 5 is L-shaped having a first attachment surface 51 and a second attachment surface 52 that are perpendicular to each other, and includes a reinforcing rib 53. The first mounting surface 51 is fixed to the uniaxial rotating body 45 of the second rotating portion 4. The second mounting surface 52 is fixed to the frame 61 of the second clamp 6.

As described above, in the drip stand connector 100 of the present embodiment, the sphere 22 that freely rotates up, down, left, and right of the first rotating portion 2 is fixed to one end of the connecting rod 1 having a length of 250 mm. A spherical body 42 which is freely rotatable in the vertical and horizontal directions of the second rotating portion 4 is fixed to the other end of the.

Further, the drip stand connector 100 has the first clamp 3 fixed to the uniaxially rotating body 25 of the first rotating section 2 that rotates uniaxially, and the uniaxially rotating body of the second rotating section 4 that rotates uniaxially. The first attachment surface 51 of the L-shaped attachment 5 is fixed to the rotating body 45, and the frame 61 of the second clamp 6 is fixed to the second attachment surface 52 of the L-shaped attachment 5 which is perpendicular to the first attachment surface 51. There is.

Further, in the drip stand connector 100, the free rotation and the uniaxial rotation of the first rotating portion 2 and the second rotating portion 4 perform the locking and unlocking operations by the respective lock knobs 26 and 46. You can do it.

As described above, since the drip stand connector 100 of the present embodiment is small in size and has many rotation points, various attachments can be made and the number of operation parts is small, so that the operation is easy.

Next, the movement of the drip stand D when the drip stand D is connected to the wheelchair W by the drip stand connector 100 will be described with reference to FIG. 5. As shown in FIG. 5, the first clamp 3 is attached to the column D1 of the drip stand D, and the second clamp 6 is attached to the handle W1 of the wheelchair W.

First, there are times when it is desired to change the position of the drip stand D with respect to the wheelchair W. For example, in a narrow corridor or a narrow passage, it is desirable to move the drip stand D to the rear of the wheelchair W. Also, in an elevator with a short depth, it is desirable to move the drip stand D to the side surface of the wheelchair W. Moreover, in a hospital room or an examination room, it is desired to move the drip stand D to a position corresponding to the room. Assuming such a case, it is preferable that the drip stand D can rotate and move with respect to the wheelchair W in as wide a range as possible.

The drip stand connector 100 of the present embodiment is configured such that the uniaxial rotation body 45 is in the unlocked state in which the sphere 42 of the second rotation unit 4 and the uniaxial rotation body 45 are unlocked. By the uniaxial rotation of 1), the first clamp 3 side can rotate 360 degrees. Therefore, the position of the drip stand D with respect to the wheelchair W can be freely changed, such as behind the wheelchair W or on the side surface of the wheelchair W.

By the way, if the mounting height of the second clamp 6 mounted on the handle W1 of the wheelchair W and the mounting height of the first clamp 3 mounted on the column D1 of the drip stand D are substantially the same, the connecting rod 1 is in a horizontal state. Therefore, as described above, it is possible to rotate the drip stand D side by 360 degrees only by the uniaxial rotation of the uniaxial rotation body 45.

On the other hand, most of the wheelchair handles W1 are inclined like the inclination angle θ3 shown in FIG. 5 (the inclination angle θ3 of the handle W1 in FIG. 5 is 10 degrees). Further, the mounting height of the first clamp 3 on the column D1 of the drip stand D is assumed to be various positions depending on the user on site.

For this reason, the connecting rod 1 is not in a horizontal state but is normally in an inclined state as shown in FIG. At this time, the state of the drip stand D becomes unstable when the position of the drip stand D is changed only by uniaxial rotation of the uniaxial rotation body 45 of the second rotating unit 4.

However, since the second rotating portion 4 is also provided with the free rotation by the spherical body 42, even if the connecting rod 1 is inclined, even if the position of the drip stand D is changed as shown in FIG. The condition is stable.

In addition, in the drip stand coupling device 100, not only the second rotating portion 4 on the wheelchair W side but also the first rotating portion 2 on the drip stand D side is rotated around the sphere 22 that freely rotates in one axis. A uniaxial rotating body 25 that moves is provided. Therefore, even if the position of the drip stand D is changed as shown in FIG. 5, the drip stand D is more stable. In addition, there may be a sloped part in the corridor in the hospital. Even if there is such an inclination, the state of the drip stand D can be made to follow the inclination by the first rotating portion 2 of the drip stand connector 100, and the drip stand D can be stabilized.

In the drip stand connector 100 of the present embodiment having such a configuration, the lock knob 46 of the second rotating portion 4 is operated to unlock the free rotation by the spherical body 42 and the uniaxial rotation by the uniaxial rotation body 45. By simply doing this, the drip stand D can be rotated and moved to the side surface or the rear side in a wide range until it hits the wheelchair W.

Further, when the wheelchair W is moving with the drip stand D, it is preferable that the lock knobs 26 and 46 of the first rotating portion 2 and the second rotating portion 4 are both in a locked state. This is because if they are not locked, the relative positions of the drip stand D and the wheelchair W may change during movement, which may cause drip leakage. In particular, when the wheelchair W curves, its relative position tends to change. Since the drip stand connector 100 of the present embodiment can be locked and unlocked only by operating one lock knob 26, 46, it is optimal for moving the wheelchair W carrying the drip stand D.

In the present embodiment, the second clamp 6 of the drip stand connector 100 is attached to the handle W1 of the wheelchair W. The second clamp 6 can be attached to other parts of the wheelchair. However, according to the verification by the present inventor, the attachment position of the second clamp 6 to the wheelchair W is preferably the handle W1 of the wheelchair W.

This is because any wheelchair W is provided with the handle W1, so that the mounting position is easy for the user to understand and the mounting positions can be unified among a plurality of users. Further, since the drip stand D is located near the person pushing the wheelchair W, it is possible to cope with an unexpected situation such as the drip stand D suddenly tilting. Also, if it is attached to the handle 1, it is unlikely that the tube extending from the drip bag will be an obstacle or that the tube is not long enough. Further, since the lock knob 46 can be operated with the patient in the visual field range, the drip stand D can be rotated with caution.

Further, when the second clamp 6 is attached to the handle W1 of the wheelchair W, it is necessary to prevent the second clamp 6 from coming into contact with the brake located under the handle W1. In this regard, in the drip stand connector 100, since the second clamp 6 is connected to the second rotating portion 4 via the L-shaped fixture 5 that changes the attachment angle of the second clamp 6 to a right angle, The clamp 6 and the brake do not interfere.

Further, the drip stand connector 100, in which the second clamp 6 is connected to the second rotating portion 4 via the L-shaped fitting 5, when the drip stand D is used as shown in FIG. The main rotation operation when rotating and moving to the rear is performed by the uniaxial rotation by the uniaxial rotating body 45 of the second rotating portion 4.

On the other hand, when the drip stand connector without the L-shaped attachment 5 or the drip stand connector 100 is attached to a part other than the handle W1 of the wheelchair W, the drip stand D is rotationally moved to the side surface or the rear of the wheelchair W. The main rotation operation at the time of making it may be performed by free rotation by the spherical body 42 of the second rotating portion 4. According to the verification by various prototypes of the present inventor, the main rotation operation when the drip stand D is rotationally moved to the side surface or the rear of the wheelchair W like the drip stand connector 100 of the present embodiment is as follows. It has been found that the uniaxial rotation by the uniaxial rotating body 45 of the two-rotating unit 4 allows the user to smoothly perform the operation and is very popular. Therefore, the configuration of the drip stand connector 100 according to the present embodiment in which the second clamp 6 is connected to the second rotating portion 4 via the L-shaped attachment 5 is preferable.

Next, FIGS. 6 to 8 are images showing an actual use example of the drip stand connector 100 of the present embodiment. FIG. 6A is an image showing a state where the drip stand connector 100 when not in use is housed in the drip stand D, and FIG. 6B shows that the first clamp 3 of FIG. It is an imaging which shows the connected state.

As shown in FIG. 6A, in the drip stand connector 100, the first clamp 3 can be detached from the drip stand D when not in use by uniaxial rotation and free rotation of the first rotating part 2 and the second rotating part 4. Instead, it can be stored in the drip stand D. Therefore, the user does not need to perform two operations of connecting to the drip stand D and connecting to the wheelchair W when using the drip stand connector 100. That is, when used as shown in FIG. 6B, the first clamp 3 remains attached to the drip stand D, and therefore the attachment operation to the drip stand D is unnecessary.

Further, the first rotating portion 2 and the second rotating portion 4 can be locked and unlocked by the single lock knobs 26 and 46 for both free rotation and uniaxial rotation, so that the drip stand connector 100 can be accommodated. Easy to put on.

7A, 7B, 8A, and 8B are images showing that the drip stand D is gradually rotated from the side surface of the wheelchair W to the rear. Since the drip stand D can be moved in a wide range in this way, the drip stand connector 100 can cope with various situations. Further, the operation of the lock knob 46 near the handle W1 is easy, and the change of the line of sight is small, so that the safety is high.

The use example of the drip stand connector 100 of the above-described embodiment is a connection to the wheelchair W, which is one of the moving devices, but the drip stand connector 100 of the present embodiment is limited to this usage method. Not something to do. Since both ends of the connecting rod 1 are provided with the first rotating portion 2 and the second rotating portion 4 that freely rotate and rotate uniaxially, the connecting rod 1 can be applied to various moving devices.

For example, the rehabilitation walker may be connected to the support column R1. FIG. 9 is a plan view showing this example of use, in which the first clamp 3 is connected to the support D1 of the drip stand D, and the second clamp 6 is connected to the support R1 of the rehab walker. Even with such a connection between the two vertical columns D1 and R1, unlocking the lock knob 46 of the second rotating portion 4 causes the first clamp 3 to rotate at an angle θ5 (θ5). Is movable in the range of θ2×2=180 degrees). As a result, the drip stand D can be rotationally moved from the side surface of the rehabilitation walker to the front and back, or from the front and back to the side surface.

In addition, in FIG. 9, both the column D1 of the drip stand D and the column R1 of the rehabilitation walker are shown as vertical columns. However, with the drip stand connector 100, the column R1 of the rehabilitation walker does not have to be vertical, and thus the drip stand connector 100 may be coupled to another column of the rehab walker. Further, when the support D1 and the support R1 are connected by the drip stand connector 100, the connecting rod 1 of the drip stand connector 100 does not need to be horizontal. Therefore, the drip stand connector 100 can be connected without worrying about the connection positions (heights) of the columns D1 and R1.
Further, in the drip stand connector of the present invention, the connecting rod may be provided with a stretching function.

[Embodiment 2]
Next, as an example of use of the drip stand connector 100, connection to a stretcher will be described. Also in the case of connection to a stretcher, in the drip stand connector 100, the first clamp 3 is connected to the column D1 of the drip stand D, and the second clamp 6 is connected to the stretcher side.

In the meantime, the stretcher is provided with a drip stand mounting portion, which is so-called a so-called gartle receiver, so that the drip stand (gartle rack) can be directly attached to the stretcher. Therefore, it seems that it is not necessary to connect the drip stand D by using the drip stand connector 100 by using the drip stand attachment portion provided on the stretcher.

However, if you attach the drip stand directly to the stretcher using the drip stand attachment part of the stretcher and move the patient with the stretcher and then transfer the patient to the bed, remove the drip stand from the stretcher and install a new drip stand. Need to be installed.

In addition, with the advancement of medical treatment in recent years, not only is the drip pack simply hung on the drip stand, but medical devices such as infusion pumps and syringe pumps and monitors that display various information are also available. A medical device is attached. If the drip stand to which such a medical device is attached is attached near the patient's head, the patient may be frightened or an unexpected accident may occur.

For this reason, it is the reality that direct attachment of the drip stand to the stretcher is rarely performed, and the merit of connecting the drip stand D to the stretcher using the drip stand connector 100 is very advantageous. large.

Therefore, the present inventor examined the mounting position on the stretcher side. However, it suffices if the stretcher side has a supporting column that corresponds to the handle W1 of the wheelchair W described in Embodiment 1 and an appropriate mounting position that corresponds to the supporting column R1 of the rehabilitation walker. When I searched for the mounting position on the stretcher side, there was a stretcher without an appropriate mounting position.

For example, in the case of an old type stretcher, there may be a cylindrical frame that is connected to the casters on the lower side of the mat (patient mounting surface) of the stretcher, so that it can be attached to the frame. On the other hand, in recent stretchers, there are many stretchers in which the number of cylindrical frames found in the old type is small or they are not used because of their high functionality and strength.

Therefore, the present inventor considers using the drip stand mounting portion provided in the stretcher instead of the stretcher main body, and first, as a connecting auxiliary tool of the drip stand connector 100 (when nothing is attached). The drip stand D is attached to the drip stand mounting portion, and the drip stand D and the stretcher are coupled by connecting the second clamp 6 of the drip stand coupling device 100 to the coupling auxiliary tool composed of the drip stand. ..

However, the drip stand used as the connecting aid is thinner than the normal drip stand, and when the second clamp 6 of the drip stand connector 100 is connected, it cannot be firmly and stably connected. Also, as a matter of course, since the drip stand as the connecting aid is excessively long, it gives a patient a feeling of pressure.

Therefore, the present inventor next connected the drip stand D and the stretcher to the drip stand connector 100 by using the dedicated coupling aid 70. The connecting aid 70 is used when connecting the drip stand D and the stretcher S using the drip stand connector 100, and the structure thereof is shown in FIG. 10. FIG. 10A is a front view of the connecting aid 70, FIG. 10B is a plan view thereof, and FIG. 10C is a right side view thereof.

Specifically, the connecting auxiliary tool 70 is L-shaped as shown in FIG. 10, and includes a fixed shaft portion 71 and a mounting shaft portion 75 extending orthogonally from the end of the fixed shaft portion 71. Become.

The fixed shaft portion 71 is a cylindrical member made of metal, and its front end side is cut into four surfaces to form four fixed surfaces 72. Although a specific example will be described later, the fixed shaft portion 71 is inserted into the drip stand mounting portion provided on the stretcher S and fixed by the fixing screw of the stretcher S and the fixed surface 72.

The mounting shaft 75 is a resin-made columnar member, and is connected to the second clamp 6 of the drip stand connector 100. A rib 76 is formed at the end of the mounting shaft 75 to prevent the second clamp 6 from coming off.

It should be noted that, more specifically, in the coupling auxiliary tool 70 of the present embodiment, the fixed shaft portion 71 and the mounting shaft portion 75 are integrated via the intermediate portion 77. However, the connecting aid 70 is not limited to such a configuration, and may have any other configuration as long as the configuration includes the fixed shaft portion 71 and the mounting shaft portion 75 orthogonal to the fixed shaft portion 71. Can be adopted. For example, the connecting auxiliary tool 70 may have a configuration in which a mounting shaft portion 75 orthogonal to the fixed shaft portion 71 is provided.

Next, the connection between the drip stand D and the stretcher S by the drip stand connection tool 100 using the connection auxiliary tool 70 will be described with reference to actual imaging shown in FIGS. Note that FIG. 11A is an image of the stretcher S before being connected, and FIGS. 11B and 11C are images of the stretcher S with the connecting auxiliary tool 70 fixed, taken from different directions. 12A to 12C are images of the stretcher S connected to the drip stand D taken from different directions.

First, the drip stand mounting portion S1 provided on the stretcher S shown in FIG. 11A is used. As described above, the drip stand mounting portion S1 is originally provided for directly mounting the drip stand (gartle rack) on the stretcher S. Further, the drip stand mounting portion S1 is usually formed by a through hole. The position and the number of the drip stand mounting portions S1 differ depending on the stretcher S.

Next, as shown in FIGS. 11B and 11C, the fixed shaft portion 71 of the connecting aid 70 is inserted into the drip stand mounting portion S1 of the stretcher S, and the fixing screw S2 of the stretcher S is turned to fix the fixed shaft portion 71. By making contact with the fixing surface 72, the auxiliary connecting tool 70 is fixed.

In addition, in the connecting auxiliary tool 70 shown in FIGS. 11 and 12, a cover 77 a is attached to an intermediate portion 77 that connects the fixed shaft portion 71 and the mounting shaft portion 75. This cover 77a is attached for the purpose of actual use and to prevent injury or damage due to contact at the intermediate portion 77.

Further, the mounting shaft portion 75 is fixed toward the outside of the stretcher S. The drip stand connector 100 can be separated from the patient who is carried by the stretcher S by moving the mounting shaft 75 outward, but this is important for alleviating the fear of the patient. ..

Next, as shown in FIGS. 12A to 12C, the second clamp 6 of the drip stand connection part 100 is connected to the attachment shaft part 75 of the connection auxiliary tool 70. At this time, the second clamp 6 may be connected to the mounting shaft portion 75 by any method, but as shown in FIG. 12, the second clamp 6 is positioned upward and the second rotating portion 4 is positioned downward. If the connection is made as described above, the operation of the holding screw of the second clamp 6 is easy. Further, the stretcher S is provided with an elevating mechanism for the patient mounting surface because it is necessary to place and lower the patient from the stretcher S. It is possible to smoothly follow the rotation of the second spherical body 22 and the rotation of the spherical body 42 of the second rotating portion 4.

As described above, when the drip stand D and the stretcher S are connected, by using the connecting aid 70 together with the drip stand connector 100, any stretcher can be easily connected. It is possible to realize smooth movement of the drip stand D.

Further, like the connecting aid 70 of the present embodiment, the configuration in which the mounting shaft portion 75 extends orthogonally from the fixed shaft portion 71 is similar to the handle W1 of the wheelchair W of the first embodiment described above. Since the mounting shaft portion 75 is in a substantially horizontal direction, when the drip stand D is rotationally moved around the stretcher S, the operation is smooth.
