Description

  The present invention relates to a wheelchair auxiliary device for moving an infusion stand on which an infusion pack or the like is suspended together with a wheelchair.

  Some patients who are admitted to hospitals need to continue infusions for medication even if they can move around the hospital. In order to allow such a person to move freely while performing infusion, for example, a caster that is movable on the floor as shown in Patent Document 1, an upright column vertically provided on the caster, and an upright stand An infusion stand provided with a hook portion for suspending an infusion pack or the like provided on the upper portion of the support column is used.

  More specifically, the standing column of the drip stand may be provided with a walking grip so that a standing person can hold or push on the drip stand. You can easily walk around by holding the grip and pushing the drip stand.

  By the way, such a grip for walking is made on the assumption that a person who can walk by himself / herself can use it, so it is not convenient for a person who can move only by a wheelchair.

  For example, as shown in FIG. 8, since the walking grip G1 is provided in the very vicinity of the upright support column T1, if the seated person P tries to pick up the walking grip G1, the drip stand T and the wheelchair K are very Must be close. Then, the front wheel of the wheelchair K and the caster T1 of the drip stand T may be too close to each other, and may not move well due to collisions.

  In order to avoid such a problem, only the hook part T3 of the drip stand T may be removed and mounted on the back surface of the wheelchair K so that the seated person P can move together with the drip pack. However, if equipment such as the infusion pump Y1 and syringe pump Y2 is attached to the drip stand T in order to adjust the flow rate of the drip as shown in FIG. 8, large and heavy equipment such as these are transferred to the wheelchair. It takes time. Furthermore, since there is a risk that an error occurs due to resetting of the pump or the like, resulting in a medical error, such a method is practically difficult to use.

  Therefore, in the hospital, as shown in FIG. 9, by wrapping the towel G2 around the upright column T2 of the drip stand T, the seater P of the wheelchair K moves the drip stand T from a position away from the walking grip G1. The drip stand T may be moved together by holding it and having the assistant S push the wheelchair K.

  However, even if such a portion that can be wrapped around the towel G2 is enlarged, as shown in FIG. 8, the seated person P of the wheelchair K holds the towel G2 in an unnatural posture such as leaning forward slightly. There is a need to continue, comfort has been impaired.

  Further, since the fixing means such as the towel G2 is not firmly fixed, it is difficult to move the drip stand T together in a stable manner in front of the wheelchair K. For this reason, in order to stabilize the movement of the drip stand T, some people may move the drip stand T between the knees, but the front wheel of the wheelchair K and the caster T1 may come into contact with each other and fall down. There is a problem with safety. In particular, such problems relating to the stability and safety of the operation become conspicuous in a situation where a certain step must be crossed when changing to an elevator in a hospital.

  As shown in FIG. 1, the wheelchair auxiliary device 100 of the present invention maintains a substantially constant distance in the state where the drip stand T that can move on the floor is disposed in front of the wheelchair K when the wheelchair K is moved. It is used for moving as it is.

  More specifically, the wheelchair auxiliary device 100 is a rod-shaped device that is attached to a standing column T2 provided on a caster T1 of the drip stand T and extends to a seated person P of the wheelchair K. During movement, the seated person P uses the wheelchair auxiliary device 100 to operate the drip stand T and the like while the wheelchair K is pushed by the assistant S.

  As shown in the perspective view of FIG. 2, the wheelchair auxiliary device 100 includes a clamp member 2 that can be attached to and detached from an upright column T <b> 2 of the drip stand T, and a seated person P of the wheelchair K from the clamp member 2. The arm 3 is configured to be stretched and the stretching length thereof is variable, and the grip 4 is provided at the tip of the arm 3 and can be gripped by the seated person P. The arm 3 is shown with an intermediate omission.

  As shown in the enlarged perspective views of FIGS. 2 and 3, the clamp member 2 has a substantially rectangular parallelepiped shape having a through-hole 26 formed so that the upright support T <b> 2 passes in the center, and is opened in two. Thus, the upright support T2 can be sandwiched. Specifically, the receiving member 21 having a substantially rectangular parallelepiped shape to which the upright column T2 is pressed, and one end of the receiving member 21 are connected by the rotary shaft 24, and the rising column T2 is pressed against the receiving unit. The pressing member 22 is provided with a tightening portion 23 for tightening the receiving member 21 and the pressing member 22 and fixing the pressing member 22 to the upright support T2.

  As shown in FIG. 4 (a), the receiving member 21 has a half of the through hole 26 provided vertically at the center of one side surface of a rectangular parallelepiped, and one end of the side surface bulges into a cylindrical shape. A connecting portion with the pressing portion is formed. A rotating shaft 24 is formed in the connecting portion in the direction in which the upright support T2 extends, and the receiving member 21 and the pressing member 22 can be opened in two as shown in FIG. 4B. It is like that. Further, a base end of a screw portion 231 of a tightening portion 23, which will be described later, is attached to the other end so as to be rotatable in a horizontal plane, and a groove 27 is formed so that the screw portion 231 protrudes outward. .

  The pressing member 22 has a substantially rectangular parallelepiped shape. One end of the pressing member 22 is connected by the connecting portion on the side where the half of the through hole 26 is formed, and the other side is shown in FIG. As shown in (c), a fitting hole is formed so that a part of a knob nut of the tightening portion 23 described later is fitted. A groove 27 is also formed in the pressing portion so that the screw portion 231 can pass outward. Further, as shown in FIG. 4C, a rubber-like displacement preventing member 25 for preventing displacement from the upright support T2 is attached to the inner surface of the through hole 26.

  The tightening portion 23 is provided on an end surface of the receiving member 21 and the pressing member 22 opposite to the connecting portion, and a screw portion 231 whose base end is rotatably attached to the receiving member 21.

  More specifically, as shown in FIGS. 4 and 5, the screw portion 231 is a denden bolt having a base end in an annular shape, and is rotatably mounted in a horizontal plane. It is provided so as to protrude from the fitting hole 221 of the abutting member 22.

The nut portion 232 is a knob nut 232 that can be manually tightened by a person, and is screwed into the screw portion 231 in advance of a countersunk screw described later. As shown in FIG. 5A, the knob nut 232 is formed by a collar with a convex portion 2322 that protrudes in a substantially cylindrical shape on the side contacting the pressing member 22 with respect to a knob 2321 that is gripped by hand. The fitting hole 221 is fitted. Since the tightening force is improved by the convex portion 2322 entering the fitting hole 221, a mechanism for preventing the deviation from the upright support T2 is formed.
In addition, the knob 2321 is fitted so as to be integrated with a nut N that is screwed in advance with a denden bolt and an adapter A for adjusting the fit.

  The drop-off prevention portion 233 is formed by providing a screw hole in the axial direction at the tip of the denden bolt and providing a countersunk screw SC having a head larger than the inner diameter of the nut N. As shown in FIG. 5B, when assembled, the countersunk screw SC is sandwiched between the knob nut 232 and the cap, and the knob nut 232 is moved outward only until the head of the countersink contacts the nut N. I can't move it. For this reason, the knob nut 232 cannot be removed from the screw portion 231, and the receiving member 21, the pressing member 22, and the tightening portion 23 can always be integrated. Therefore, the knob nut 232 is lost after being dropped from the screw portion 231, and the problem that the function as the clamp portion 2 cannot be exhibited can be eliminated. For example, there are patients who easily lose such connecting parts in a hospital, and the effect of making the knob nut 232 unremovable in this way becomes more remarkable. Conversely, as shown in FIG. 5C, the knob nut 232 can be moved inward only until the head of the countersunk screw SC hits the cap, and is always in a position suitable for tightening the pressing member 22. A knob nut 232 can be placed on the screw.

  Further, the clamp member 2 is formed with a thin plate bent in a substantially U-shape, and is provided with a bracket B provided along the upright support T2.

The arm main body 32 has a substantially round bar shape extending toward the seated person P side.

  As shown in FIG. 3, the fixing member 31 has an arm body insertion hole 312 for passing the arm body 32 in a direction orthogonal to the upright column T <b> 2, and is orthogonal to the insertion hole 312. A pin fixing hole 311 extending in the same direction as the column T2 is formed.

  As shown in FIG. 6, the arm main body 32 has two parallel flat surfaces 322 formed on the side surface of the round bar, and the cross section is a substantially track-shaped member. The arm 3 insertion hole has the same shape, and the direction in which the arm body 32 is inserted is fixed. A plurality of pin insertion holes 321 are formed in the radial direction in the curved surface portion of the side surface that is the base end portion of the arm main body 32 at regular intervals. The length of the arm body 32 extending toward the seated person P of the wheelchair K can be adjusted simply by changing the position of the pin insertion hole 321 with respect to the pin fixing hole 311 and inserting the pin. The length of the arm body 32 in the axial direction is at least long enough to keep the front wheel of the wheelchair K and the caster T1 of the drip stand T from contacting each other. It also has an extra length so that it can be adjusted to the size of P.

  As shown in FIG. 6, the grip portion 4 is a substantially round bar-shaped member provided so as to extend from the tip of the arm body 32 to both sides in the horizontal direction, that is, to the left and right directions of the seated person P. In other words, the arm 3 and the grip portion 4 form a T-shaped rod.

  The length of the grip portion 4 in the left-right direction is about the width of a person's shoulder, and as shown in the figure, the length extending toward the clamp portion 2 is longer than the opposite side. . In other words, when viewed from the seated person P, the drip stand T can be pushed and pulled without being biased so that the substantially central portion of the grip portion 4 and the upright support column T2 are arranged in a substantially straight line. It is.

  A rubber cover 41 is provided at each tip of the grip portion 4 so as not to slip when the seated person P grips it.

  According to the wheelchair auxiliary device 100 configured as described above, since the length of the arm 3 extending from the drip stand T toward the seated person P can be adjusted, the wheelchair K is adapted to the size of the seated person P. The front wheel and the caster T1 of the drip stand T do not collide with each other, and the drip stand T can be set at a distance that can be easily operated from the wheelchair K. Moreover, since the clamp part 2 can adjust the attachment position with respect to the upright support | pillar T2, the height of the grip part 4 in the front-end | tip of the said arm 3 can also be adjusted, and it can be made the position where the seated person P is easy to grasp. .

  In other words, since there is an extension length and height adjustment mechanism, the distance between the wheelchair K and the drip stand T in front of the wheelchair K when moving in the wheelchair K is a safe distance with a low risk of falling and an easy posture. However, the moving direction of the drip stand T can be easily set to a distance that can be operated. Therefore, compared with the case where the drip stand T is moved together with the wheelchair K using the conventional towel, the safety and the comfort of the seated person P can be improved.

  Further, the grip portion 4 is formed so as to extend in the left-right direction from the distal end portion of the arm main body 32, and for example, a person with a physical disability such as a rheumatic patient can easily grasp it. Moreover, since it can hold | grip firmly with both hands, the stability of operation of the drip stand T can be improved. For this reason, even if there are some steps on the floor, it is easy to pass safely.

  Other embodiments will be described.

  In the embodiment, the arm 3 is fixed with respect to the clamp portion 2. However, as shown in FIG. 7, the angle formed by the arm 3 and the upright support T2 can be changed. Good.

  Moreover, in the said embodiment, although the grip part extended | stretched in the left-right direction from the front-end | tip of an arm, other shapes may be sufficient. For example, it is configured only with an arm, and a rubber cover may be put on the tip of the arm body to form a grip portion.

  The mechanism for adjusting the length by which the arm portion extends is not limited to a pin. For example, the arm body may have a telescopic structure.

  In addition, various modifications and combinations of embodiments may be performed without departing from the spirit of the present invention.
