Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a sitting position stretcher that makes it possible to force the user to sit with his or her knees upright.

[Conventional technology]

When bathing a bedridden patient, a patient after surgery, or a physically disabled person who is unable to walk without a wheelchair, transport means such as a stretcher or transfer table are normally used, but in order to allow the patient to be transported and bathed in a sitting position,
A stretcher attached to a support with casters is sometimes used in the frame consisting of the backrest and seat.

[Problem that the invention attempts to solve]

In most of the conventional stretchers mentioned above, the backrest part of the frame is attached to an elevating column, and the patient, who is transferred from the bed and sits down on the seat, stretches his legs on the flat, horizontal seat. You can take a comfortable sitting position by resting your back against the backrest. However, if you bathe in a sitting position with your legs extended,
Patients with impaired consciousness do not move and simply remain still, so there are problems such as the effect of exercise therapy that can be obtained by moving the body in a bathing state with good blood circulation.

[Means for solving problems]

This invention solves the above problem, and includes a frame consisting of a backrest part and a seat part, a column supporting this frame, and a column provided on the seat part of the frame in an inverted V shape so that it can be opened and closed. A movable plate consisting of a thigh resting plate and a shin resting plate which are connected to each other so as to be flexible, supporting the legs of a person seated on the seat and forcing a kneeling posture according to the degree of opening; and a movable plate near the top of the support. The gist of the present invention is to provide a bending/extending means for bending/extending the knee by opening/closing the thigh resting plate and the shin resting plate of the movable plate to an arbitrary opening degree by operating an operating part provided in the movable plate.

[Effect]

This idea includes a movable plate consisting of a thigh resting plate and a shin resting plate which are connected to each other so as to be able to bend freely and which can force the knees into any desired bending and stretching state, on the seat part of a frame consisting of a backrest part and a seat part. By operating an operating section provided near the top of the column supporting the frame, the thigh resting plate and the shin resting plate of the movable plate are opened and closed as desired, and the knee is flexed and extended.

The main frame 4 includes a backrest portion 4a, an extendable seat portion 4b, a mounting plate 4c, and the like. A pillow frame 5 is attached to the upper part of the backrest part 4a, and armrests 6 are attached to both sides of the substantially central part of the backrest part 4a.

A lumbar rest plate 7, a thigh rest plate 8, a shin rest plate 9, and a foot rest frame 10 are sequentially connected to the upper surface of the seat portion 4b. The thigh resting board 8 and the shin resting board 9 are movable boards, and can be opened and closed in an inverted V shape according to the legs of the person sitting. That is, the connecting portion between the foot rest frame 10 and the shin rest plate 9 is supported by a telescoping rod 11 provided in the seat portion 4b so as to be able to move forward and backward. You can make them take it. Note that the telescopic rod 11 is biased in the direction of protruding from the seat 4b by a spring 12 fitted within the seat 4b.

One end of a belt 13 is wrapped around the end of the footrest frame 10, and the belt 13 is attached to a roller 14 at the lower end of the backrest 4a.
The other end is wrapped around a belt pulley 16 that is coaxial with a worm wheel 15 built into the top of the housing.
Worm gear 1 meshing with worm wheel 15
The shaft 17a of 7 connects the main frame 4 to the hydraulic cylinder 3.
A sprocket 18 is attached to the end of the shaft 17a. This sprocket 18 is for transmitting rotational power from a manual handle 19 as an operation part to the worm gear 17, and is connected between the sprocket 18 and the sprocket 20 assembled to the handle shaft 19a held by the mounting plate 4c. A chain 21 is stretched over the chain 21.

In this embodiment, a manual handle 19, a sprocket 20, a chain 21, a sprocket 18,
The worm gear 17, the worm wheel 15, the belt 13, and the like constitute a bending/stretching means.

Further, in this embodiment, a loop-shaped lift lever 22 is provided at the top of the hydraulic cylinder 3, and by reciprocating the lift lever 22 up and down, the hydraulic cylinder 3 together with the main frame 4 is raised and lowered. be able to. Further, band fasteners 23 are attached to the sides of the backrest portion 4a and the shin rest plate 9 so that a band for fixing the body position can be fastened thereto.

When bathing and cleaning the whole body of a patient who has suffered a head injury due to a car accident or the like and has severe consciousness disturbance, first the patient lying on the bed is transferred to the main frame 4 in a sitting position. . In this case, each plate 7, 8,
9 extends in a straight line, and the hydraulic cylinder 3
is also at its lowest height. In addition, in a case where the patient's recovery from impaired consciousness is slow, it is preferable to wrap a band around the backrest portion 4a and the shin rest plate 9 to secure the patient's waist and legs.

In this way, the sitting stretcher 1 on which the patient in the sitting position has been transferred is transported to the side of the bathtub 24 shown by the dashed line in FIG. Push it up to a position higher than the edge of the Furthermore, the lower frame 2 is attached to the bathtub 24 so that the seat portion 4b is located directly above the bathtub 24.
and enter the gap between the floor and the floor. Then, the lift lever 22 is reciprocated again to immerse the seat portion 4b into the bathtub 24, so that the patient is fully immersed in the hot water.

After the whole body is bathed in this manner, the hand wheel 19 is rotated, and the belt pulley 16 is rotated by rotational force via the sprockets 20, 19, the worm gear 17, etc., and the belt 13 is wound up. As the belt 13 is wound up, the telescopic rod 11 is pulled into the seat 4b against the spring 12. As a result, the shin rest plate 9 and the thigh rest plate 8 are in an inverted V.
The patient stands up in a kneeling position. Therefore, the patient can passively take a kneeling position in a bathing state with good blood circulation, and the patient's recovery from impaired consciousness can be accelerated.

In addition, by rotating the manual handle 19 in the forward and reverse directions, the knee can be bent and extended.
Exercise therapy that involves repeated bending and stretching is possible. In addition, when straightening the knee, use handwheel 1.
