Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a human body for providing an elderly person with a weak leg, a physically handicapped person or the like to a bed from a wheelchair or to a wheelchair and a toilet seat, a shower chair, a sofa, a car seat or the like. Regarding a transfer device.

2. Description of the Related Art Conventionally, as a transfer device of this kind, "a main column is erected so as to be tiltable on a turntable and a receiving plate is provided at the tip thereof" (Japanese Patent Publication No. 1-1958575), or a belt is applied to the belly. There are things that support and lift the weight by doing so. The present inventor has also previously proposed “human body transfer device”, 1990 patent application No. 12837. However, there was no transfer device capable of performing a transfer with a large height difference only by holding the upper body. That is, a. There are cases in which the body of the person being assisted is not adequately held during transfer assistance, and both arms rise in a veiled fashion, and the waist does not rise sufficiently. B. Further, in the case of a person who mainly holds the weight by applying the belt under the waist, the belt must be attached or removed under the waist of the person being assisted who is sitting in a wheelchair or a toilet seat. However, this is a complicated and difficult task for the caregiver, and it is uncomfortable for the care recipient. C. In addition, because it was not possible to assist in the removal and removal of pants, pants, etc. using the transfer device, there is also a case where the care recipient's self-esteem is hurt and exposed to the cold because of the prior and subsequent removal at other places away from the toilet. There were many.

[0003]

The problem to be solved by the present invention is to eliminate the method of lifting the belt under the waist when transferring in the body transfer device, and abolishing "the trunk is held only by optimally holding the upper body." Lifting ". For that purpose, it is important to grasp the area around the armpit. That is, a. The front side, both sides, and the rear side of the armpit are properly retained. B. It is desirable that both sides, which are important for supporting weight, are always in close contact with each other, even when used by a plurality of assisted persons having different physiques, and support the body while giving lateral pressure. C. For those with hemiplegia, it is necessary to consider that they can be worn on each side of the arm. D. It should be easy and easy for an elderly and weak woman to use at home. E. Satisfy the small size and light weight of the equipment. And so on.

[0004]

A main pillar (2) is provided on a pedestal (1) having casters, and a branch pillar (3) tiltable from a position (o) corresponding to the knee height of the main pillar is provided. Put out, and insert a joint column (4) that supports the body holder in a unified manner.
On the other hand, the pedal is taken out from the midpoint (p) of the main pillar, and linked with the branch pillar by the link (6). In the upper body retainer equipped on the human body transfer device configured as described above, the person receiving assistance receives the component force (p) acting at a right angle to the trunk when standing forward while standing upright. Hold it. (Above Fig. 2. Fig. 4 Fig. 1
The force component (F) in the trunk direction is carried by placing both sides on two arm bars (12) opened in a substantially horizontal figure eight shape. This arm bar has a hinge block (11) rotatably attached to the axis of the handle (8).
Its end is connected by a pin (13) and opened in the direction of the person being assisted in the shape of a figure that can be opened and closed, and is supported from below by a sliding fitting (9) whose center is arranged substantially orthogonally. The second half of the arm bar is warped. It is optimal that the sliding fittings have a downward inclination from both the left and right sides toward the center, and the arm bar is placed on the inclined surface. (See Figure 2 and Figure 5 above)

For those who cannot move their arms together, the hinge blocks are separately provided so that the above-mentioned arm bars can be independently moved. (See FIG. 6) In a general-purpose "human body transfer device", fan-shaped gears are provided to face each other at two hinge axes, and the left and right arm bars are always centered with respect to each other by linking these with the arm bars. It is easy to use if the structure moves symmetrically. (Refer to FIG. 7) "Claim 4" is a structure for applying lateral pressure to both sides by a method different from "Claim 1". That is, two arm bars are connected to a hinge block fixed to a handle shaft in a non-rotatable manner by pins that can be opened and closed in a substantially horizontal eight shape. The feature of the present invention resides in that the axes (l) and (m) of the pin are paired with respect to the vertical line to the left and right, and are tilted by an appropriate angle in the y-direction and x-direction components. (Fig. 8. Fig. 9)

[0006]

With the above-described transfer device, transfer from a bed to a wheelchair or the like is performed in the following procedure. (See FIG. 4.) Bring the device close to the person being assisted in a sitting posture, place your foot on the pedestal, and bring the knee close to the knee rest. Tilt the branches and apply the belly pad, put the arm bar that has been opened in advance on the armpit, and place it on the sliding metal fittings. Both arms should be in a natural position with armrests (1
0). At that time, the joint struts are expanded and contracted as necessary according to the body. The caregiver pulls the handle (8) toward you while stepping on the pedal. Then, the body of the person being assisted tilts and stands up, and transfers from the bed to the transfer machine. At this time, although not shown, when the branch column rotates to the upper limit, it hits the stopper and the lock is automatically applied to maintain its posture. Then, the transfer device is appropriately changed in direction and moved to bring it closer to the wheelchair. After that, unlock the car, step on the pedal, put your body on the wheelchair, and the transfer is completed. Since the rear end of the arm bar is warped, it prevents the body from falling backward while sitting.

[0007] In the series of operations described above, the holding of the body will be described by capturing the time when the body tends to be most unstable and stands up. I. The knee is restrained from wobbling by the arcuate knee pad (14). The abdominal pad supports the abdomen and bears the component force P of the body weight W _{1 in} the direction perpendicular to the trunk. (See FIG. 10) b. The two arm bars enter the armpit in a horizontal figure eight,
Carry half W _1/2 of each body weight on each side. Since the arm bar is on the inclined surface of the sliding metal fitting, the body is tightened by the side pressure T and it cannot slip off. (See FIGS. 1 and 5) c. With regard to "claim 2", the left and right arm bars can be treated separately. D. With regard to "claim 3", for example, by moving one arm bar with one hand, both arm bars can be moved symmetrically at the same time, and the center of the body of the person being assisted can be prevented from collapsing laterally. E. The structure of "Claim 4" is different from that of "Claim 1", but the axis (l) of each arm bar is symmetrically inclined.
And to rotate about the (m), resulting lateral pressure T when multiplied by the weight W _1/2, is sandwiched the body from both sides. (See FIG. 8 and FIG. 9)

[Effects of the Invention] When an elderly person, a physically handicapped person, etc. perform mutual transfer with a bed, a toilet seat, a shower chair, etc. centering around a wheelchair, "in principle, transfer with a large height difference only by holding the upper body" It is in the point that made it possible. That is, a belly pad is provided, and separately from that, by hinge support, the arm bar is arranged in a shape of a figure with an approximately appropriate angle to the human body and supports both sides, which supports the body by the combined force of weight and lateral pressure. Because it is held, it is automatically and firmly held regardless of the size of the chest. As a result, the caregiver does not have to wear a belt on the back of the person being assisted who sits in a wheelchair or a toilet seat, which is complicated and requires physical strength, and the person being assisted is relieved from the discomfort of the belting. In addition, since it is possible to maintain the posture of standing upright only by holding the upper body, it is possible to use the transfer device to assist in the attachment and detachment of pants and pants.

[00011] The "claim 2" is applied to hemiplegic patients due to the aftereffects of stroke, etc., and has an effect that the arm bar can be attached and detached for each arm. According to claim 3, if the caregiver moves either one of the arm bars, the other one also moves symmetrically, which is convenient for putting on and taking off, and once attached, it has the effect of keeping the body centered. .. With the increase in the number of persons being assisted, home care is often given to elderly women, and it is a great social effect that a transfer device that can be easily and easily handled by a weak person can be provided.
