Description

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

  In a medical facility, a patient during infusion may move on a wheelchair, stretcher, rehabilitation walker, or other mobile device with a drip stand with casters. At this time, a drip stand connector for connecting the drip stand to the moving device has been conceived so that a person does not have to hold the drip stand.

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

  Patent Document 2 describes a drip stand connector for connecting a drip stand to a wheelchair with a grip for gripping both parallel handles of the wheelchair and a crossbar connecting means for connecting to a crossbar below the wheelchair. When not in use, the left and right grips are removed from the handle and rotated downward to close, and the crossbar connecting means protruding forward is removed from the wheelchair crossbar and rotated downward. Thus, when not in use, the drip stand connector is left attached to the drip stand.

  Patent Document 3 describes a drip stand connector that has clamps at both ends of a connecting rod and connects the drip stand to a wheelchair. The two clamps can be rotated on axes parallel to each other and fixed to the connecting rod at an arbitrary angle. Can be linked. As shown in FIG. 2 of the publication, when not in use, the clamp is stored with both clamps of the drip stand connector attached to the cylinder of the drip stand.

  There are various shapes of wheelchairs and stretchers to which a drip stand with casters is connected, and a drip stand connector that can connect the drip stand to any shape and any position is preferable. Moreover, it is preferable that the drip stand connector can be connected to a rehabilitation walker that is not described in Patent Documents 1 to 3. In addition, it is preferable that the drip stand connector can easily move the drip stand before and after a moving instrument such as a wheelchair or the like depending on the situation such as passage in a corridor or getting on and off an elevator. Moreover, it is preferable that the drip stand connector can be accommodated compactly when not in use. Moreover, it is preferable that it can be easily applied to a reclining wheelchair or stretcher. Thus, many things are desired for the infusion stand connector mainly used in hospitals.

  On the other hand, the drip stand connector of Patent Document 1 cannot fix the relative positions of the drip stand and the moving device because the flexible rod is not a rigid body. For this reason, since a flexible rod deform | transforms unexpectedly during a movement and the relative position of an infusion stand and a moving instrument changes, there exists danger, such as an infusion leak, and is unpreferable.

  The drip stand connector of Patent Document 2 can be applied only to a wheelchair with a parallel handle and a crossbar. In addition, the drip stand can only be connected to the back of the wheelchair, and applicable moving instruments are very limited.

  The drip stand connector of Patent Document 3 can only be connected to the inclined pipe-shaped portion of the moving device at the position of the drip stand column that is flush with it. For example, an upright drip stand cannot be connected to the side of a wheelchair for a wheelchair whose wheel legs are inclined forward. Also, since the distance between the two clamps is always constant, the area occupied by traffic and parking is large. Further, when the drip stand connector is removed from the drip stand and accommodated on the moving instrument side when not in use, it is difficult to accommodate on the moving instrument side.

  An object of the present invention is to provide a general drip stand connector that can be applied to various shapes of moving devices such as wheelchairs, stretchers, and rehabilitation walker. It is another object of the present invention to provide a drip stand connector that can easily change the position of the drip stand before, after, or on the side of a moving instrument and can be compactly accommodated when not in use.

  In order to achieve the above object, the drip stand connector of the present invention includes a first clamp attached to the drip stand side, a second clamp attached to the moving device side, the first clamp, and the second clamp. A drip stand connector for connecting the drip stand to the moving device, wherein at least one position of the first clamp and the second clamp is connected to the connecting rod 1. It is possible to move along.

  Thereby, the distance of the instrument for a movement and an infusion stand can be adjusted easily. Also, when the drip stand connector is not in use, leave the drip stand connector attached to either the drip stand or the moving device and remove only the other to reduce the distance between the first clamp and the second clamp. Then, the drip stand connector can be stored compactly in the moving device or the drip stand. For example, the drip stand connector can be pushed into the stretcher S to reduce the protruding dimension from the caster.

  In the drip stand connector according to the present invention, the first clamp and the second clamp can be rotated and fixed on mutually parallel axes, and the first clamp and the second clamp. It is preferable that at least one of these can be rotated and fixed in axial directions other than the parallel axes.

  Accordingly, since at least one of the first clamp and the second clamp can be rotated in the other axial directions, even if the axis of the drip stand and the cylinder of the moving instrument are not on the same plane, they have different heights. The first clamp and the second clamp can be attached. For example, a drip stand can be connected to the side of a wheelchair even in a wheelchair in which the feet of the wheel are inclined forward. Thereby, the kind of movement instruments, such as a wheelchair which can connect the drip stand with a caster, increases.

  In the drip stand connector according to the present invention, it is preferable that the first clamp and the second clamp are held by the connecting rod so as to be rotatable in two axial directions or in a free direction.

  Thereby, the drip stand can be moved back and forth or sideways of the moving device depending on the situation while the drip stand connecting device is connected to the drip stand and the moving device. For example, when moving in a narrow place, the drip stand is moved behind the moving device, and when the elevator is short in depth, the drip stand is moved to the side of the moving device. Moreover, when the moving instrument has a reclining function, the angle of the backrest of the moving instrument can be changed while the drip stand connector is attached to the moving instrument.

However, the embodiments shown below are not intended to limit the present invention to those described herein, and The invention can be equally applied to various modifications without departing from the technical idea shown in the claims. In addition, in each drawing used for the description in this specification, in order to make each member a size that can be recognized on the drawing, each member is displayed with a different scale, and is not necessarily actual. It is not displayed in proportion to the dimensions.

[Embodiment]
The structure of the principal part of the coupler 100 for drip stands of embodiment is demonstrated using FIGS. The drip stand connector 100 connects the drip stand D with casters to a moving instrument such as the wheelchair W, the stretcher S, and the rehabilitation walker R. In addition, the drip stand D, the wheelchair W, the stretcher S, and the rehabilitation walker R are shown in FIG.

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

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

  The free rotating portion 2 has the same configuration as a general free pan head, and includes a ball 21, a column 22 that is integrated with the ball 21 and to which the first clamp 3 is fixed, and a column 22 that protrudes to protrude the ball 21. The ball holding portion 23 includes an opening that is partially exposed and holds the ball 21 so as to be freely rotatable, and a free rotation fixing screw 24 that is attached to the ball holding portion 23 and fixes the free rotation of the ball 21.

  The first clamp 3 includes a frame 31 having a “U” shape (a shape close to a U shape) fixed to the support 22 of the free rotating portion 2, and two first shafts 32 penetrating the opposite surfaces of the frame 31. The first handshake 33 and the second handshake 34 are pivotally supported at one end, respectively, and the gripping screw 36 is pivotally supported at the other end of the first handshake 33 by the second shaft 35.

  The first handshake 33 and the second handshake 34 are rotated so as to sandwich the drip stand D or the pipe-shaped portion P of the moving device, and each of the sandwiched portions has an acrylic V-shaped contact portion. 37. In addition, since the contact part 37 is a synthetic resin acrylic, it is difficult to damage the drip stand D or the moving instrument.

  In a state where the drip stand D or the movement device is sandwiched, a grip screw 36 pivotally supported by the first handshake 33 is fitted into a notch groove 38 of the second handshake 34, and a stopper 39 provided on the second handshake 34 is inserted. Screwed in at the abutted position. As a result, the distance between the first handshake 33 and the second handshake 34 in the sandwiched state is grasped, and the screw 36 is shortened to firmly fix the first clamp 3 to the drip stand D or the moving device. In addition, since the dimension which the 1st handshake 33 and the 2nd handshake 34 pinch can be changed with the holding screw 36, the diameter of the pipe shape part P to hold may differ. Further, since the two V-shaped contact portions 37 are sandwiched and gripped, the pipe-shaped portion P to be gripped does not necessarily have a circular cross section. In the present embodiment, the second clamp 6 is a common component having the same shape as the first clamp 3.

  The sliding part 4 has a groove 411 and a sliding cylinder 41 having a C-shaped sliding section, a sliding fixing screw 42 that narrows the width of the groove 411 and fixes sliding and rotation, and sliding The connecting portion 43 is integrally formed with the cylinder 41 and has a hole (not shown) that is rotatably held by the biaxial rotating portion 5.

  The biaxial rotating portion 5 rotates the sliding portion 4 by the shaft 51 to which the second clamp 6 is fixed, the biaxial fixing screw 52, and the biaxial fixing screw 52 being threaded and inserted. The biaxial holding part 53 which hold | maintains so that a shaft 51 can be rotated is comprised.

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

  As described above, the drip stand connector 100 of the present embodiment has the first clamp 3 that can be freely rotated and fixed to the one end of the connecting rod 1 by the free rotating portion 2, and the connecting rod 1 by the sliding portion 4. The second clamp 6 is configured to be slidable / rotatable and capable of fixing sliding / rotation, and can be rotated in the biaxial direction by the biaxial rotating portion 5 to be able to fix the rotation.

  Thereby, since the 1st clamp 3 and the 2nd clamp 6 can rotate with a mutually parallel axis | shaft, if the angle of the axis | shaft of the pipe-shaped part P to grasp is the same plane, the 1st clamp 3 and the 2nd clamp 6 Even if the gripping height changes, it can be connected. Furthermore, since at least one of the first clamp and the second clamp can be rotated in the axial direction other than the parallel axis, the first clamp 3 and the second clamp can be connected to each other even if the angle of the axis of the pipe-shaped portion P to be gripped is not the same plane. The two clamps 6 can be connected even if the gripping height changes. Furthermore, since the distance between the 1st clamp 3 and the 2nd clamp 6 can be changed along the connecting rod 1, the position grasped may change while grasping both. Further, when not in use, the drip stand connector 100 can be accommodated in a compact manner with one of the first clamp 3 and the second clamp 6 removed and the other attached. Moreover, the 1st clamp 3 and the 2nd clamp 6 are applicable also to the diameter and shape from which the pipe shape part P of a movement instrument differs. The drip stand D may be attached to either the first clamp 3 or the second clamp 6.

[First use example]
Next, the 1st usage example of the coupling tool 100 for drip stands of embodiment is demonstrated using FIG. As shown in FIG. 6A, the first clamp 3 is attached to the stretcher S, and the second clamp 6 is attached to the drip stand D.

  When the drip stand connector 100 is not used, the second clamp 6 is detached from the drip stand D while the second clamp 6 is attached to the stretcher S as shown in FIG. Thus, the connecting rod 1 and the first clamp 3 are pushed into the stretcher S and stored compactly. At this time, since the work for attaching the second clamp 6 to the stretcher S is not required at the time of use, it is possible to shorten the time for attaching the drip stand connector 100, and the effect is great in an emergency.

  In addition, when not in use, only the second clamp 6 is removed, and the connecting rod 1 and the second clamp 6 are rotated by the rotation of the free rotating portion 2, and the second clamp 6 is attached to the drip stand D, whereby the drip stand The connecting tool 100 may be housed in the support of the drip stand D. Also at this time, since the distance between the first clamp 3 and the second clamp 6 can be shortened by sliding of the sliding portion 4, it can be accommodated in the drip stand D without removing both the clamps 3 and 6.

[Second use example]
Next, the 2nd usage example of the coupling tool 100 for drip stands of embodiment is demonstrated using FIG. The first clamp 3 is attached to the drip stand D, and the second clamp 6 is attached to the wheelchair W. The drip stand D is disposed next to the wheelchair W.

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

  Therefore, the inclination direction of the connecting rod 1 can be changed by the free rotation of the first clamp 3 and the rotation of the second clamp 6. Further, the distance between the first clamp 3 and the second clamp 6 can be changed by sliding the second clamp 6. For this reason, even if the 1st clamp 3 and the 2nd clamp 6 are attached to the drip stand D and the wheelchair W, the drip stand D can be moved behind the wheelchair W. Conversely, the drip stand D can be moved sideways from behind the wheelchair W.

  For example, when moving the wheelchair W with the drip stand D, it is easier to move if the drip stand D is next to the wheelchair W. However, it is better to have the drip stand D behind the wheelchair W in a narrow hallway or a narrow elevator. The same applies to the stretcher S of the first usage example. That is, since the stretcher S is long, when the infusion stand D is connected to the stretcher S and rides on an elevator having a small depth, the infusion stand D should be next to the stretcher S.

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

[Third use example]
Next, the 3rd usage example of the connector 100 for drip stands of embodiment is demonstrated using FIG. 8, FIG. FIG. 8 is an image in which the drip stand connector 100 is connected to the drip stand D and the wheelchair W with the reclining, and FIG. 9 is a diagram for explaining an operation in which the reclining is tilted in the direction to lie down. is there.

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

  By tilting the reclining in the direction to lay down, the center of rotation of the first clamp 3 moves from the point B1 to B3. Here, the point B2 is a position when the center of rotation of the first clamp 3 is an extension of the point O and the point A. Of B1, B2 and B3, the point closest to the point A is at the point B2. This can be understood from the triangle B1 · O · A and the triangle B3 · O · A. That is, when the second clamp 6 slides, the distance between the first clamp 3 and the second clamp 6 becomes the shortest when the center of rotation of the first clamp 3 is at the position B2. Thus, the distance between the first clamp 3 and the second clamp 6 that accompanies reclining changes.

  Also, the angle α1 formed by the line B1 · O and the line B1 · A is opposite to the angle α3 formed by the line B3 · O and the line B3 · A, so that the first clamp 3 has the absolute value of α1 and α3. It will rotate by the sum of absolute values of. On the other hand, the second clamp 6 rotates by an angle β which is the angles B1, A, and B3. Thus, the rotation angle of the 1st clamp 3 accompanying a reclining and the rotation angle of the 2nd clamp 6 differ.

  Thus, in the drip stand connector 100 of the present embodiment, both the first clamp 3 and the second clamp 6 can rotate in parallel with the reclining axis, and the second clamp 6 slides to the first position. Since the distance between the first clamp 3 and the second clamp 6 can be changed, the reclining angle can be easily changed without removing the first clamp 3 and the second clamp 6. Since the first clamp 3 is free rotation and the second clamp 6 is biaxial rotation and rotation of the sliding portion 4, even if there is an attachment error of the drip stand connector 100, the reclining angle is changed lightly. can do.

[Fourth use example]
Next, the 4th usage example of the connector 100 for drip stands of embodiment is demonstrated using FIG. In FIG. 10, the drip stand connector 100 connects the drip stand D and the rehabilitation walker R. During use with the rehabilitation walker R, a situation may occur in which the drip stand D is moved according to the surrounding environment while the user himself / herself walks. Therefore, the drip stand connector 100 that can cope with various positional relationships between the rehabilitation walker R and the drip stand D is very preferable. As described above, the drip stand connector 100 of the present embodiment can also be applied to moving instruments other than the stretcher S and the wheelchair W.

  In the drip stand connector 100 of the present invention, the first clamp 3 may be held so as to be rotatable about two axes, or the second clamp 6 may be held so as to be freely rotatable. Moreover, about sliding, at least any one of the 1st clamp 3 and the 2nd clamp 6 should just slide. The purpose of this sliding is to make it possible to change the position of at least one of the first clamp 3 and the second clamp 6 along the connecting rod. Therefore, instead of sliding, the expansion / contraction function of the connecting rod 1 is used. Thus, even if the distance between the first clamp 3 and the second clamp 6 can be changed along the connecting rod, the same effect can be obtained.
