Description

  The present invention relates to an assistance method and an assistance device for assisting a posture change between a sitting position and a standing position in a person being assisted.

  For example, when assisting the transfer of the person being assisted from the bed to the wheelchair, it is difficult only with the helper's power.

  Therefore, conventionally, for example, an assistance device as shown in FIG. 15 (hereinafter, a conventional example) has been proposed as an assistance device used when assisting a posture change between a sitting position and a standing position of a person being assisted. .

  This conventional example is composed of a base 51 having a grounding portion 51a, and a peristaltic strut 52 pivotally attached to the base 51 so as to be rotatable in the vertical direction. Is provided with an upper body support portion 55 for supporting the upper body of the person being assisted. For example, when the posture is changed from a sitting position to a standing position using this conventional example, In this state, the upper body (between the chest and the abdomen) is placed on 55, and in this state, the peristaltic column part 52 is swung while raising the buttocks, so that the patient stands up from the sitting position. The conventional operation is performed under the assistance of a caregiver.

  By the way, the conventional example rotates with a smaller force as the angle R1 formed by the horizontal line Y and the straight line X connecting the center of gravity P of the person being assisted and the rotation axis A of the base 51 and the peristaltic column 52 is larger. Since this is possible, the angle R1 is increased by shortening the length of the base 51.

  However, in the conventional example, the upper body has to be bent deeply in the actual posture change, and the person being assisted has a large burden such as being bent forward too much and the chest and abdomen being compressed (available assistance Are limited).

  However, as shown in FIG. 16, if the base 51 is lengthened and the rotation axis A between the base 51 and the peristaltic support column 52 is set to the upper position, the chest and abdomen of the person being assisted are not bent forward too much. Although the pressure is not pressed and the load is reduced, the angle R2 formed by the straight line X connecting the rotation axis A between the base 51 and the peristaltic support column 52 and the horizontal line Y becomes small, and the direction in which the posture changes from the sitting position to the standing position is reduced. Accordingly, the force F for raising the person being assisted until standing is increased, which increases the burden on the assistant.

The tip 3 is pivotally attached to the part 3 a so as to be rotatable in the front-rear direction, and the tip is pivotally attached to the second connecting part 5 a provided in the upper body support part 5.

  That is, the second part 4 has rotating shafts 12a, 12b, 12c, and 12d at a total of four positions, that is, a base end portion and a distal end portion, and the centers of the rotating shafts 12a, 12b, 12c, and 12d are at the apexes of a rectangle. It arrange | positions, and it arrange | positions at the vertex of an unequal-sided rectangle from which the distance between the rotating shafts 12a and 12b in this 1st connection part 3a differs from the distance between the rotating shafts 12c and 12d in the 2nd connection part 5a. By doing so, it becomes possible to independently adjust the advance distance and the forward bending angle of the person being assisted.

  Specifically, FIGS. 4A and 4B show the distance between the rotating shafts 12c and 12d in the second connecting portion 5a as compared to the distance between the rotating shafts 12a and 12b of the first connecting portion 3a.

  Further, the swinging part 2 is provided with a bending rotation range restricting part 7.

  As shown in FIGS. 1 to 3, the bending rotation range restricting portion 7 includes a first convex portion 7 a provided on the tip side inner surface portion of the first part 3 and a position near the rotation shaft portion, and a second portion. 4 and a second convex portion 7b that slides along a guide groove 4a provided on the inner surface of the base end side.

  When the first part 3 and the second part 4 are bent, the first convex part 7a is in contact with the inner surface of the base part side of the second part 4 (rod-like member 4B), so that the bending rotation is restricted. . At this time, the second convex portion 7b is retracted to a position where it does not contact the first convex portion 7a.

  Moreover, when the 2nd convex part 7b is slid and distribute | arranged to the rotation shaft part vicinity position and the 1st part 3 and the 2nd part 4 are bent in this state, the 1st convex part 7a and the 2nd convex part 7b And the bending rotation is restricted in a narrower range (the bending rotation amount is limited to be reduced).

  The scene in which the second convex portion 7b is brought into contact with the first convex portion 7a is a case where it is better not to bend too much (when it is not desired to accumulate large energizing energy in the energizing energy generating structure 6), Used when changing posture from sitting to sitting. The bending rotation range restricting portion 7 is configured to be able to restrict the bending rotation of the first part 3 and the second part 4 (the energizing energy accumulated in the energizing energy generating structure 6 is limited). The configuration may be zero), and is not limited to the structure described above.

  The first part 3 and the second part 4 are provided with a biasing energy generating structure 6 that generates biasing energy with respect to the bending rotation of the first part 3 and the second part 4. .

  As shown in FIGS. 1 and 2, the energizing energy generating structure 6 is provided with a spring 6b (coil spring) covered on a guide rod 6a installed between connecting portions provided in the first part 3 and the second part 4. The biasing energy is accumulated when the first part 3 and the second part 4 are bent, and the biasing energy is exerted in the direction in which the first part 3 and the second part 4 extend. It is configured.

  The energizing energy generating structure 6 is not limited to a spring, but a spring that has not been preloaded, a spring that has been preloaded, a gas spring, or a weight to be described later, due to the ability of the person being assisted to maintain the leg force or the standing position. The structure which obtains energizing energy with the weight of the body 9 may be sufficient.

  In the present embodiment, the pair of left and right base portions 1 are provided with a pair of left and right peristaltic portions 2 (first and second portions), but one base portion 1 is provided with one peristaltic portion 2. Although the structure may be sufficient and the base 1 and the peristaltic part 2 are made of metal, the material is not limited to metal.

  An assistance method using the assistance device having the above configuration will be described. In this embodiment, the apparatus is used with the assistance of a caregiver, but it may be used by the person being assisted.

  When changing the posture from sitting to standing while sitting on the seat 11, the upper body support 5 is applied to the upper body (around the chest and abdomen) of the person being assisted in the sitting position (FIG. 5 (a)). In this state, when the caregiver pulls the handle 10 by applying a force substantially horizontally, the caregiver is bent forward while rubbing the buttocks (see FIG. 5B). At this time, energizing energy is accumulated in the energizing energy generating structure 6 when the first part 3 and the second part 4 are bent (this is the first step in the claims). At this time, the first convex portion 7a of the bending rotation restricting portion 7 is brought into contact with the inner surface portion on the proximal end side of the second portion 4 (rod-like member 4B) so that the first portion 3 and the second portion 4 are bent. The rotation is restricted.

  Subsequently, when the caregiver starts up the person being assisted, the energizing energy accumulated in the energizing energy generating structure 6 is released (this is the second step in the claims), accompanied by the assistance of this assistant. The person being assisted is urged (assisted) (see FIGS. 5C and 5D).

  The posture change from the sitting position to the standing position will be described in detail.

  In the above-described conventional example, the supporter's buttocks move away from the seating surface immediately after the posture change starts, and at this time, the force F necessary for the posture change is maximized, and it is necessary to apply a force forward and upward. In the assistance device of the present embodiment, for example, when a gas spring is used for the urging energy generating structure 6, the force corresponding to the gas reaction force of the gas spring immediately after the start of the posture change, and the supporter's buttocks and the seat surface Although it is necessary to apply a force corresponding to the friction force forward, it is not necessary to apply a force upward until the forward bend position because the buttocks of the person being assisted and the seating surface are in contact. When, for example, a compression spring that does not apply preload is used for the biasing energy generating structure 6, the force required immediately after the start of transition is only a force corresponding to the frictional force between the buttocks of the person being assisted and the seating surface. As the spring advances, the force that must be applied to the front increases, but the force by which the spring pushes up the person being assisted increases, so the friction force between the buttocks and the seating surface of the person being assisted decreases. Furthermore, since the horizontal distance between the rotation shaft 1c and the center of gravity of the person being assisted is shortened and the angle formed by the straight line connecting the rotation axis 1c and the center of gravity of the person being assisted and the horizontal line is increased, the force of the spring pushing up the person being assisted Thus, the ratio of the force by which the spring pushes back the person being assisted is reduced. In other words, the weight of the person being assisted becomes the main force that pushes and shrinks the spring. Accordingly, the force that needs to be applied forward during advancement from the sitting position to the forward bending position increases initially but decreases midway. Since the linear distance between the rotary shaft 1c and the center of gravity of the person being assisted is reduced during forward movement and the torque that rotates backward is reduced, it is effective for the assistant to operate the handle 10 only during forward movement.

  It is desirable to provide a mechanism for limiting the movable range of the stopper or the like so that the first part 3 does not rotate further forward when the person being assisted reaches the forward bending position in the transition from the sitting position to the standing position. This prevents the person being assisted from falling forward, and the position of the rotating shaft is fixed, so that the person's movement path is uniquely determined, and the transition from the forward bending position to the standing position is stabilized. A damper or the like may be used as a mechanism for limiting the movable range so as to absorb the impact. In addition, it is desirable to provide a mechanism for limiting a movable range such as a stopper so that the second portion 4 does not drop too much at this position. This movable range limitation is to prevent slipping from the seat surface of the person being assisted, and may be adjusted so that the limitation is effective at a position where the second portion 4 is slightly lowered from the forward bending position.

  In addition, in the transition from the sitting position to the standing position, after the person being assisted reaches the forward bending position, the second part 4 is turned upward about the rotation shafts 12a and 12b. In the forward bending position, the urging energy generating structure 6 accumulates urging energy by large elastic deformation, and assists the force for turning the person being assisted upward. It is desirable that the turning direction be 45 ° or less with respect to the horizontal line immediately before the standing position where the assisting force of the biasing energy generating structure 6 decreases, thereby reducing the force applied in the turning direction. In the standing position, it is desirable to provide a mechanism for limiting the movable range by a stopper or the like so that the second portion 4 does not turn further forward. This prevents the person being assisted from falling forward. Moreover, you may fix so that one or both of the 1st part 3 and the 2nd part 4 may not be moved by a stopper or a brake in a standing position. The standing position is preferably adjusted so that the horizontal position of the center of gravity of the person being assisted is slightly ahead of the horizontal position of the rotary shaft 1c. good.

  Next, when the posture is changed from the standing position to the sitting position, the upper body support body 5 is applied to the upper body of the person being assisted in the standing position (see FIG. 6A). The person being assisted is bent while grasping (see FIG. 6B). In addition, the 2nd convex part 7b of the bending | flexion rotation range control part 7 is previously slid and distribute | arranged to the rotation shaft part vicinity position. At this time, energizing energy is accumulated in the energizing energy generating structure 6 when the first part 3 and the second part 4 are bent (this is the third step in the claims). Further, the first portion 3 and the second portion 4 are bent, the first convex portion 7a is in contact with the second convex portion 7b, and the bending rotation is restricted within a narrow range. That is, the energizing energy accumulated in the third process is an energizing energy smaller than the energizing energy accumulated in the first process.

  Subsequently, when the caregiver sits so that the person being assisted lowers the buttocks to the seat 11, the energizing energy accumulated in the energizing energy generating structure 6 is released (this is the fourth step in the claims). The sitting movement of the person being assisted with the assistance of the assistant is performed in a state in which the person is urged (assisted) a little (see FIGS. 6C and 6D).

  The posture change from the standing position to the sitting position will be described in detail.

  The posture change from the standing position to the sitting position may be performed in the opposite direction to the posture change from the sitting position to the standing position, but in this embodiment, as described above, the posture change from the standing position to the sitting position is energized. The accumulation amount (elastic deformation amount) of energizing energy of the energy generating structure 6 is limited or set to zero, and the transition from the sitting position to the standing position is performed. That is, since the amount of urging energy stored is small, the force and distance that the person being assisted is pushed backward from the time of sitting to the sitting position is reduced, and the risk that the person being assisted falls backward is also reduced. Further, since the turning radius around the rotating shaft 1c is increased, the seat can be seated more deeply.

  Therefore, according to this embodiment, unlike the above-described conventional example, the posture change between the sitting position and the standing position can be easily performed with a small force, and further, no special power is required and the cost is reduced.

  In the present embodiment, the first part 3 and the second part 4 are provided with a bending rotation range restricting part 7 for restricting the bending rotation range of the first part 3 and the second part 4. Therefore, it is useful when, for example, it is better not to bend (when it is not desired to store large energizing energy in the energizing energy 6), that is, when the posture is changed from the standing position to the sitting position.

  Further, in this embodiment, as the biasing energy generating structure 6, the biasing energy generating structure 6 that exerts biasing energy by the elasticity of an elastic body such as a spring or a gas spring is adopted, or the weight of the weight body 9 is used. Since the energizing energy generating structure 6 that exerts energizing energy is employed, the above-described excellent operational effects are surely exhibited even without special power.

Because of the structure in which the pivoting portion 8 with the second part 4 approaches the person being assisted, the person being assisted can be advanced with a smaller force.

  Reference numeral 16 indicates that when the first part 3 and the second part 4 are bent and the first part 3 is rotated with respect to the base part 1, the first part 3 and the second part 4 are brought into contact with the second part 4 and rolled.
