Description

  The present invention assists a care receiver who is difficult to stand by himself from a sitting state, and further assists maintenance of the standing state, thereby mainly assisting rehabilitation of the leg. About.

  As this type of conventional nursing assistance device, there is known a device that can be moved up and down while holding a pair of left and right arms in a horizontal state (for example, see Patent Document 1). In this device, the arm portion is attached to the tip of the double link, and the posture of the arm portion is maintained horizontal even when the arm portion is moved up and down by the action of the double link. Then, both arm portions are inserted into the armpit of the care recipient in the seated state, and the arm portions are raised in this state, thereby assisting the care receiver to stand up.

  In addition, although it is not strictly standing assistance, the nursing device of the same structure is known (refer patent document 2). This is also equipped with a pair of left and right arm parts, and the cared person in the sitting state is slightly lifted from the chair or separately, and the belt is bridged between both arm parts so as to be positioned under the buttocks in that state. . Accordingly, the cared person sits on the belt and moves to the toilet or the like with the arm part inserted in the armpit.

As belts, belts covering from the waist to the buttocks and belts that are turned around the back are used to lift the cared person diagonally upward with these belts while holding the knee of the cared person in the seated state. And what was made to raise the upper body with the knee joint of a cared person as a fulcrum is known (refer patent document 2).
Japanese Patent Laying-Open No. 2003-325582 (FIG. 2) JP-A-9-84832 (FIG. 1) Japanese Patent Laid-Open No. 9-570 (FIGS. 9 and 14)

  The care assisting device described in Patent Document 1 and the care device described in Patent Document 2 have a common configuration in which a care recipient is lifted by both arms from a sitting state. Both devices have a problem that no means for holding the back of the cared person is provided when the cared person is lifted by both arms.

  That is, the level of care required of the care recipient is not the same, and not only a care recipient who can support his / her weight with his / her leg but also a care recipient who cannot support his / her weight with his / her leg. When a care recipient whose leg strength is so weak that he cannot support his weight with such a leg is lifted by the device as described above, the care recipient feels anxiety that he may fall backward, and the care recipient From the side, it is very dissatisfied. If a safety belt is placed between the tips of the arms while the cared person is lifted, it may be possible to prevent the cared person from falling backward, but there is a safety belt on the back of the cared person. Because it does not come in contact with the pressure of, the caregiver who can not see the back is still anxious.

  Moreover, although the arm part is attached to the tip of the swing arm in the one described in Patent Document 1, it is set to swing upward from a tilted state so that the tip of the swing arm is below the horizontal position. ing. In the state where the cared person is seated, the leg portion is located in front of the trunk portion, and in order to stand up as it is, the trunk portion must be moved to above the leg portion.

  However, in the care assisting device described in Patent Document 1, since the cared person is lifted from a state where the tip of the swing arm is inclined downward, the cared person's torso is opposed to approaching the upper part of the leg. Therefore, the position of the cared person becomes extremely unnatural with the trunk raised.

  Moreover, in the thing of patent document 3, since a knee is fixed and an upper body is pulled up by using a knee joint as a fulcrum, a big force acts on a knee joint. Therefore, there is a problem that it cannot be used for a care recipient who has weak muscle strength to assist the knee joint or a care recipient who has a knee joint failure such as rheumatism. Furthermore, even if the cared person can stand up, the upper body is fixed with a belt and the legs are fixed with knee pads, so that the entire body is completely restrained and rehabilitated in the standing state. It is completely impossible to exercise.

  In view of the above problems, an object of the present invention is to provide a care assisting device that does not cause the above-described problems and can further assist in the rehabilitation of the care recipient in the standing state.

  In order to solve the above-described problem, a care assisting device according to the present invention includes a pair of left and right arms that are inserted into the armpits of a seated cared person, and the arm part ascends to raise the arm. In a care assisting device that assists a person in standing and assists in maintaining the standing state of the cared person in a standing state, the distal end portion of the arm portion is freely bent inward and is positioned between the arm portions. It is characterized by supporting the caregiver's back.

  The care receiver can give a sense of being held by a human by bending the distal end portion of the arm portion inward.

  Furthermore, by providing a breast pad that comes into contact with the chest of the cared person while supporting the cared person's back with the tip of the arm part, the cared person is held from the front, back, left, and right and held by a human being You can feel the feeling of being stronger.

  By the way, a swing arm that swings up and down around the base end is provided, and the arm portion and the breastplate are attached to the tip of the swing arm, and the swing arm is in a substantially horizontal state and the arm portion is in a seated state. It is set to be inserted into the armpit of the cared person, and when the tip of the arm is bent inward, it is displaced diagonally up and down so that the tip of each other does not overlap in the front-rear direction It is desirable to make it so.

  By configuring in this way, even if the arm is raised and the swinging arm is tilted, the to-be-cared person's torso remains in a substantially vertical state. Push forward. By this action, even when the tip of the arm is lightly touched to the back of the cared person before the arm is lifted, the tip of the arm becomes the back of the cared person as the arm rises. The force to press increases. As a result, when the cared person stands, the cared person's body is securely held by the breastplate and the arm.

  When standing up for a while for rehabilitation, etc., the device can be stored in the device so that it is safe even if the caregiver leaves the place, preventing the device from falling in the left-right direction. It is desirable to provide a fall prevention means.

  In addition, a wheel that moves the entire device in the horizontal direction is provided, and a tread plate that allows the cared person to stand upright and touches the sole of the cared person is detachable, and the wheel is grounded with the tread plate removed. If the care receiver is able to move the legs by touching the floor of the cared person to the ground and the device can be moved by the leg power of the cared person, walk training with the footboard removed If the cared person is unable to move the legs, the feet can be placed on the tread board.

  Further, when the cared person stands up, if the cared person's weight is received only by the arm part, the armpit of the cared person in contact with the arm part becomes painful. In such a case, the breast pad is inclined so that the cared person is covered with the breast pad when the cared person is seated, and the cared person shifts from the seated state to the standing state. It is desirable to be continuously changed to a state substantially perpendicular to the floor surface.

  When the cared person is seated, the weight of the cared person can be received not only by the arm part but also by the breast pad, and is distributed to the arm part and the breast pad. Pain is alleviated when the portion receiving weight is dispersed in this way. On the other hand, in the standing state, receiving weight with a breastplate causes problems such as suffocation. Therefore, when the cared person stands, the breast pad is almost perpendicular to the floor surface so that it does not receive weight. When the cared person stands, the weight of the cared person is supported by the leg part of the cared person in addition to the arm part, so the armpit does not hurt.

  As is apparent from the above description, the present invention can provide the cared person with a sense of security similar to the state in which the person holds the cared person and assists when the cared person is standing. it can.

  Referring to FIG. 1, in the care assisting device according to the present invention, a vertical fixing column 1 is mounted on a base 11. Frames 2 are connected to the left and right sides of the base 11, respectively. The frame 2 is hollow, and openings 21 are provided on the outer sides of both the frames 2. A swingable fall prevention leg 22 is stored in the frame 2, and the fall prevention leg 22 can be pulled out from the opening 21. A landing portion 23 that swings in the vertical direction is attached to the tip of the fall prevention leg 22. The fall prevention leg 22 is pulled out, and the landing portion 23 is in a vertical state as shown in the drawing in the left-right direction of the entire apparatus. To prevent falling. If the landing portion 23 is returned horizontally and the fall prevention leg 22 is returned into the frame 2, the entire apparatus can be moved by the wheels 24 and 25.

  A slide column 3 that slides in the vertical direction is attached to the fixed column 1, and the slide column 3 is adjusted to a desired height and fixed to the fixed column 1. Further, a handle 31 used for movement is attached to the slide column 3.

  A swing arm 4 is swingably attached to the upper end portion of the slide column 3. Slide members 41 are attached to the tip of the swing arm 4 on the left and right, respectively. Each slide member 41 can adjust the left and right positions. Each slide member 41 has an arm portion 5 attached thereto. Therefore, by adjusting the left and right positions of the slide member 41, the distance between both arm portions 5 can be adjusted according to the physique of the cared person.

  The arm portion 5 is covered with a cushion material 50, and fixed pipes 5 </ b> L and 5 </ b> R fixed to the slide member 41 are built in the cushion material 50. Two movable pipes 51 and 52 are connected to the distal ends of the fixed pipes 5L and 5R. Each of the movable pipes 51 and 52 is bent without resistance in a direction to be bent inward, but is connected through a ratchet mechanism in which a lock works in a return direction.

  Reference numerals 53 and 54 denote release levers for releasing the ratchet mechanism. When the release levers 53 and 54 are operated, the movable pipes 51 and 52 can be returned to the original state, and the distal end portion of the arm portion 5 is linear. Can be. The movable pipes 51 and 52 are set not to bend in the horizontal direction when bent inward, but to bend so that the tip portion of the arm portion 5 is inclined upward.

  Further, a breast pad 6 is attached to the swing arm 4 via a spring 61. If the chest of the cared person presses the breast pad 6, the spring 61 contracts to relieve stress between the breast and the breast pad 6, and allow the breast pad 6 to be tilted in the horizontal and vertical directions.

  An electric piston 7 is installed between the swing arm 4 and the slide column 3. The electric piston 7 includes a telescopic rod 71, and the length of the rod 71 can be freely expanded and contracted by being operated by the controller 72. The power source of the electric piston 7 may be a battery (not shown) or may use a lamp line.

  Reference numeral 8 denotes a tread board that is detachably mounted across the frames 2 and is made of resin to reduce the weight. Moreover, since the upper surface is a surface that comes into contact with the sole of the care recipient, the upper surface is covered with a foaming resin layer in order to provide anti-slip and heat retaining properties. On this tread board 8, for example, a rehabilitation instrument such as a stepper can be set. Reference numeral 40 denotes a grip held by the care recipient.

  When using the above-mentioned care assisting device, with the movable pipes 51 and 52 of both arms 5 made straight, they are brought closer to the seated care recipient from the front, and both arms 5 are taken care of. Insert the arm 5 into the armpit of the person.

  Referring to FIG. 2, arm 5 is inserted under the armpit to the position where the chest of the care recipient NC is lightly in contact with breastplate 6, and the movable pipes 51 and 52 of arm 5 are bent inward in this state. The tip portion 5T of the part 5 is lightly brought into contact with the back of the care recipient NC. When the rod 71 of the electric piston 7 is extended in this state, the swing arm 4 is tilted and the arm portion 5 is raised as shown in FIG. As the arm portion 5 rises, the care recipient NC is lifted upward.

  Since the swing arm 4 is operated from a horizontal state, the arm portion 5 is lifted as the swing arm 4 swings and is lifted while pulling the care recipient NC forward. Therefore, the body part of the cared person NC moves to above the leg part, and the cared person NC is in a natural state in a standing state.

  Since the tip portion 5T of the arm portion 5 is bent obliquely upward, the tip portion 5T approaches the back portion of the care recipient NC and pushes the back portion when the arm portion 5 rises and tilts. . Then, in the sitting state, the horizontal distance between the breast pad 6 and the tip part 5T that was only lightly in contact with the chest or back of the cared person NC is reduced, and the cared person NC is firmly attached by the breast pad 6 and the tip part 5T. Will be held.

  After the cared person NC stands up in this way, the care assisting device may be moved and transported to the place where the cared person NC is desired. The tread board 8 can be removed and moved while performing walking training.

  Further, when the standing state is maintained for a while at the destination, the fall prevention leg 22 is pulled out to prevent the fall in the left-right direction.

  In the present embodiment, since the base end portion of the arm portion 5 is curved upward, even if the arm portion 5 is tilted in a state where the care recipient NC is standing, the care recipient is along the arm portion 5. There is no worry that the NC slides forward.

  Next, a second embodiment will be described with reference to FIGS. In the second embodiment, the swing arms 4a and 4b are paired up and down. Moreover, the arm part 5 was attached to the right and left of the breast pad 6 attached to the front-end | tip of both the rocking | fluctuation arms 4a and 4b. Note that both the breastplate 6 and the arm 5 are covered with a hard sponge, and the surface thereof is further covered with a low repulsion material, so that stress can be concentrated on a part of the body of the care recipient NC as much as possible. It is configured so as to prevent it.

  The inner surface of the distal end portion 5a of the arm portion 5 and the surface of the breast pad 6 are particularly thickly provided with a low repulsion material, thereby softening the contact with the care recipient NC. Further, the breast pad 6 is provided with protruding portions 6a on the left and right sides, and the armpit of the care recipient NC is placed on the protruding portion 6a.

  In this state, when the arm portion 5 is bent inward, as shown in FIG. 5, the positions of the both end portions 6 a are shifted vertically so that the both end portions 5 a do not overlap in the front-rear direction.

  Further, as shown in FIG. 6, the swing arms 4a and 4b are not parallel, and the distance x between the fulcrums on the slide column 3 side is made larger than the distance y between the fulcrums on the breastplate 6 side. Then, when the care recipient NC is seated, the breastplate 6 is tilted so as to face upward.

  When the swing arms 5a and 5b are swung upward from this state, the chest pad 6 rises, but when the cared person NC stands up, the breast pad 6 is displaced so that the inclination of the chest pad 6 is almost eliminated. This is because the fulcrum distances x and y are made different, but in addition to this, the lengths of the swing arms 4a and 4b may be made different.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
