Description

Detailed Description of the Invention

  The present invention relates to a wheelchair or chair seat used by a hemiplegic patient in daily life.

  The seat surface of a ready-made wheelchair or chair is horizontal to the floor surface. Seats that can be adjusted in height, seats that are tilted in the front-rear direction, and cushions that have been invented for the purpose of spreading the seat pressure so that you can sit for a long time have been invented. There is no seat.

Problems to be solved by the invention

  At present, the seating surface on which a hemiplegic patient is sitting in daily life is horizontal to the floor as in a healthy person. However, the body of hemiplegic patients is different from that of healthy people. It is in a state of reduced supportability on the paralyzed side, reduced elasticity of the muscle on the paralyzed side, and muscle atrophy due to disuse on the paralyzed side. In this state, if a hemiplegic patient sits on a seating surface horizontal to the floor surface, as shown in FIG. It often slips and the pelvis is in a collapsed posture leaning toward the paralyzed side.

  To maintain this collapsed posture, hemiplegic patients use the healthy upper and lower limbs. Therefore, the healthy upper and lower limbs of hemiplegic patients are always in a strong state and lose their freedom. Operations and operations performed in such a state are difficult for hemiplegic patients. The start-up operation is very difficult and often requires assistance. It is difficult to perform tasks and actions in a sitting position such as eating, dressing, changing clothes, wheelchair driving, and hobby activities. Also, sitting in a collapsed posture places a burden on various places and often causes pain.

  The degree of paralysis in hemiplegic patients varies from individual to severe. And the degree of recovery from paralysis varies from individual to individual. Therefore, the degree to which the sciatic bone slides toward the paralysis side on the soft tissue of the buttocks that is in contact with the seating surface varies depending on the degree of paralysis and the degree of recovery of the paralysis. That is, the degree of the collapsed posture in which the pelvis is inclined to the paralyzed side is different depending on the individual.

  The problem to be solved by the present invention is that the phenomenon of the sciatic bone sliding on the soft tissue of the buttocks in contact with the seating surface is slid toward the healthy side without the human hand. The point is to provide a seating surface to be modified. Another object of the present invention is to provide a seating surface that can adjust the degree to which the sciatic bone slides on the soft tissue according to the degree of paralysis or the degree of recovery from the paralysis.

Means for solving the problem

  If a hemiplegic patient sits on a seating surface that is horizontal to the floor as in a normal person, the sciatic bone slides on the soft tissue and the pelvis tilts toward the paralyzed side as shown in FIG. It becomes a posture. Work and operations performed in a standing motion or sitting posture are difficult to perform, and pain often appears at the burden site. The inventor of the present invention thought that such a drawback would be reduced if the seating surface of a wheelchair or chair used by a hemiplegic patient in daily life was a seating surface with an inclination rising to the paralysis side.

  The seating surface according to the present invention is a seating surface installed on the seating surface of a wheelchair or a chair used by a hemiplegic patient in daily life.

  The seating surface according to claim 1 is inclined so that one side of the left and right is higher and the other side is lower. On the seating surface of a wheelchair or chair on which a hemiplegic patient sits in daily life, a seating surface that is inclined so that the paralyzed side is high and the healthy side is low is installed. If a hemiplegic patient sits on this inclined seat, it will be as shown in FIG. The pelvis is raised to the paralyzed side, the sciatic bone is applied with a force toward the healthy side by gravity and drag, and the soft tissue in contact with the seat surface is applied with a force against the seat surface in the paralyzed side direction. As a result, it is possible to correct the sciatic bone to slide toward the healthy side on the soft tissue without the intervention of a human hand.

  Further, in order to adjust the degree to which the sciatic bone slides on the soft tissue according to the degree of paralysis or the recovery degree of the paralysis, the inclination angle can be adjusted as in the seating surface according to claim 2. . As shown in FIG. 3, the seat plate 1 and the bottom plate 2 are connected, and one side is connected by a hinge 3. Do not fix the other side. By adjusting the height between the seat plate 1 and the bottom plate 2 on the non-fixed side, the inclination angle can be adjusted.

  The inclination angle increases as the degree of paralysis is more severe and the lowering angle of the pelvis side is larger, that is, the degree of posture collapse is larger. On the other hand, the inclination angle is reduced as the degree of paralysis is mild and the degree of posture collapse is small. In addition, the most suitable inclination angle for an individual is selected by adjusting the inclination angle to be small in accordance with the recovery of paralysis due to rehabilitation.

  The seating surfaces shown in claims 1 and 2 do not consider the durability of the buttocks when sitting for a long time. At present, cushions intended to disperse sitting pressure, such as a low resilience cushion, are often prescribed on the seating surface of hemiplegic patients so that they can sit for a long time. When it is desired to use this cushion, it is used by installing it on the seating surface of claims 1 and 2. However, as a disadvantage of this case, the trouble of having to purchase separately comes out. The bearing surface according to claim 3 is for eliminating the troublesomeness. The cushion member which has a pressure dispersion function is attached on the inclined seating surface board of Claim 1 and Claim 2.

Example 1
A first embodiment will be described with reference to FIGS. 3, 4, and 5. As shown in FIG. 3, the seat plate 1 and the bottom plate 2 are connected, and one side is connected by a hinge 3. Do not fix the other side. As shown in FIG. 4, a non-slip sheet 4 is attached to the lower surface of the bottom plate 2 so that the seat surface does not slip. An elastic and frictional member 5 is attached to the upper surface of the seating surface plate 1. As shown in FIG. 5, the seat surface is inclined by packing a towel or a newspaper whose height can be adjusted by folding or overlapping between the seat surface plate 1 and the bottom plate 2 on the non-fixed side. Adjust the tilt angle by adjusting the amount of towels and newspapers folded or stacked. This is placed on the wheelchair or chair seat. A pressure dispersion cushion or cushion is laid on top of this to be used as a seating surface for hemiplegic patients. Moreover, since the elastic member is attached to the upper surface of the seat surface board 1, it is good also to use as it is, without laying a pressure dispersion cushion or a cushion. Since the direction of use is different between right and left paralysis, use it so that the paralysis side becomes higher by flipping left and right.

Example 2
A second embodiment will be described with reference to FIGS. 6, 7, 8, 9, 10, and 11. FIG. A mechanism for tilting the seat surface and a mechanism for adjusting the tilt angle of the seat surface are as follows. Other configurations are the same as those in the first embodiment. A component 6 having grooves A, B, C, and D as shown in FIG. 6 is attached to the upper surface of the bottom plate 2 as shown in FIG. A movable component 7 as shown in FIGS. 7, 8, and 9 is attached to the lower surface of the seat plate 1 as shown in FIG. As shown in FIG. 11, the seat surface is inclined by hooking the component 7 into any of the grooves A, B, C, and D of the component 6. The seat surface inclination angle is adjusted by changing the positions of the grooves A, B, C, and D of the component 6. Used in the same manner as in Example 1.

Example 3
A third embodiment will be described with reference to FIGS. 12, 13, 14, and 15. FIG. A mechanism for tilting the seat surface and a mechanism for adjusting the tilt angle of the seat surface are as follows. Other configurations are the same as those in the second embodiment. Instead of the part 7 used in the second embodiment, a part 8 as shown in FIGS. 12, 13, and 14 is used. Attach as shown in FIG. As shown in FIG. 16, the seat surface inclination angle is adjusted by changing the length of the component 8. Used in the same manner as in Example 1.

Example 4
A fourth embodiment will be described with reference to FIG. The upper surface of the seating surface plate 1 of the first embodiment, the second embodiment, and the third embodiment is an elastic and frictional member 5. This portion is made of a low resilience cushion member having a pressure dispersion function.

The invention's effect

  If a hemiplegic patient whose posture collapses in daily life uses the inclined seating surface according to claims 1, 2, and 3 of the present invention, the collapsed posture is used by human hands. It can be corrected without going through. Moreover, if the seat surface which can adjust the inclination | tilt angle which concerns on Claim 2 and Claim 3 of this invention is used, an inclination | tilt angle can be adjusted with the grade of paralysis or the recovery | restoration degree of paralysis. As a result, the freedom of the healthy upper and lower limbs that have been active to maintain the collapsed sitting posture is acquired, and the following effects are obtained. The assistance amount of the rising motion is reduced or the degree of independence is improved. Work and movements in a sitting position such as eating, dressing, changing clothes, wheelchair driving and hobby activities become easier. Reduces stress on the burdened part.
