Description

  The present invention relates to a transfer assist device having a hugging arm for holding a body of a person who needs care or the like.

  Conventionally, when a caregiver cares for a cared person who needs care, such as an elderly person, a person with a weak leg, a person with a disability, etc., the caregiver has moved from the bed to a wheelchair or toilet, etc. Has been done. In such a transfer work, the caregiver bends his waist and turns his arms from the arm of the cared person to the back, while holding the cared person a little while standing and changing the body direction of the cared person. is there. However, the operation of hugging a person to be cared and standing or sitting takes a caregiver's weight, which is heavy for the carer and easily causes back pain or the like.

  Therefore, a transfer device has been proposed for reducing the burden of the caregiver's transfer work. For example, a transfer assist device disclosed in Patent Document 1 includes a shaft, a handle that is at the upper end portion of the shaft and that is responsible for the back and forth movement of the device, a grounding member that is at the lower end portion of the shaft and contacts the floor surface, A body holding member is provided that protrudes laterally from the middle of the shaft and receives the front side of the body of the care recipient. The body holding member is provided with a torso holding shaft portion that supports the chest of the care recipient and an armpit holding portion that supports the buttocks. The grounding member is formed with a curve that rolls on the floor surface in a direction parallel to the protruding direction of the body holding member. This rolling direction is a direction parallel to the median sagittal plane that is a plane that divides the human body into left and right and that passes through the midline.

  The method of using this transfer support device is to support the body of a cared person sitting at the end of a bed or the like with a body holding member, and the caregiver applies force to the handle to rotate the transfer support apparatus, so that the cared person I will lift up my body and take a standing position. At this time, according to the bottom shape of the grounding member, the device moves to the caregiver side and changes the direction of the care recipient who is in the standing position by operating the handle with the curved portion of the bottom shape of the grounding member as a fulcrum. Then, it is transferred by carrying it in the reverse order of lifting. At this time, it is possible to easily get over a handrail such as a wheelchair due to the standing position and the posture drawn to the caregiver.

  Moreover, the transfer assistance instrument disclosed in Patent Document 2 is provided with a shaft, a handle, and a grounding member, and a human body gripping tool is provided in the middle of the shaft. The human body gripping tool is provided with a breast support plate that supports the chest of the cared person and a heel support arm that is attached so as to freely rotate in the vertical direction of the breast support plate and supports the human body during transfer. The heel support arm has an L-shaped structure that can hold the caregiver's heel and back, can be opened and closed left and right with an attached lever, and can be operated so as to sandwich the body from the left and right.

  In this method of using the transfer assist device, first, the arm of the cared person is hugged from the left and right by operating the armrest support arm with a lever. Next, if you move the shaft with the handle to lift the cared person's body, a moment due to the cared person's weight is generated around the axis for rotating the armrest support arm up and down, and automatically The body can be hugged from the back to the chest and supported firmly. In other words, the body is hugged using the component of the weight of the cared person.

  In addition, the human body transfer devices disclosed in Patent Document 3, Patent Document 4, and Patent Document 5 are provided with a main column standing on a pedestal having casters, and a tiltable branch column is provided from the main column. A holder for holding the cared person's body is provided at the tip. Further, a tiltable pedal connected to the tilt of the branch pillar is provided at the lower part of the main pillar, and a handle is provided at the upper part of the support pillar. This transfer device can tilt the branch pole by a link mechanism or the like, and can lift the cared person by the principle of lever. After the lifting, the pedestal having the casters is moved and hung in the reverse motion to assist the transfer.

  In the case of the above-described background art, the transfer assist device of Patent Document 1 does not have a holding tool that holds the cared person's body so as to be hugged, and there is a risk that the tool may fall out of the device toward the back side of the cared person. On the other hand, the transfer assist device of Patent Document 2 has hugged the body using the component of the weight of the cared person, but is hugging when the weight is not sufficiently applied to the armrest support arm such as lifting or hugging. The effect was small and I felt uneasy. In addition, although the left and right movements of the heel support arm passively pinch the caregiver, the care receiver himself closes the heel and relies heavily on the arm strength of the care receiver who rides on the heel support arm, and the arm strength is extremely lost It may not be applicable in the case of a care recipient. Further, since the spring and the plurality of rotation fulcrums are provided, there is a problem that the structure is complicated and the weight is increased.

  The human body transfer devices disclosed in Patent Documents 3 to 5 are unstable because there is no holding tool for holding the body of the care recipient so as to hug. In Patent Document 3, a belt that wraps around the back of the body is provided, but the work efficiency is not good because the belt is fastened each time. Furthermore, since the human body transfer apparatuses of Patent Documents 3 to 5 are provided with accessory parts such as a cart with a caster and a stopper, they are heavy and difficult to carry as they are.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 7 show an embodiment of the present invention. A transfer support device 10 of this embodiment is provided with a metal shaft 12 having an appropriate strength at the center, and an upper end portion 12 a of the shaft 12. Is provided with a belly pad 14 for receiving the front side of the body of the care recipient 46 who needs care. The belly pad 14 is provided with a rod-shaped bell pad 16 that is connected at right angles from the tip of the shaft 12, and a cushion 18 wound around the bell pad 16. Note that the upper end portion 12 a of the shaft 12 is connected to the center in the longitudinal direction of the belly pad portion 14.

  A pair of hugging arms 20 that receive the armpit of the body of the cared person 46 are provided at both ends of the belly pad 16. As will be described later with respect to the longitudinal direction of the belly pad 14, the hugging arm 20 is pivotally supported so as to be rotatable about an axis provided at a predetermined angle θ. The width of the pair of hugging arm portions 20 is substantially the same as or slightly larger than the width of both sides of the body of the cared person 46.

  The hugging arm portion 20 includes a vertical axis portion 22 that is rotatably supported around an axis at a predetermined angle θ with respect to the longitudinal direction of the belly pad portion 14 at both ends of the belly pad portion 14, and a vertical axis portion There are provided a horizontal shaft portion 24 fixed at a right angle to the front end portion of 22 and a back shaft portion 26 fixed at a right angle to the front end portion of the horizontal shaft portion 24 and projecting downward in parallel to the vertical axis portion 22. It has been.

  Here, the predetermined angle θ may be set so that the pair of hugging arms 20 opens and closes in the direction of hugging the body of the cared person 46 when rotated. For example, in a state where the shaft 12 is inclined by 30 ° with respect to the vertical direction and the belly pad 14 is in contact with the lower abdomen of the cared person 46, the predetermined angle θ is set on the surface parallel to the horizontal plane. What is necessary is just to set to 30 degrees with respect to the longitudinal direction of the contact part 14, for example. Moreover, even if the body width of the cared person 46 is different when the hugging arm part 20 is rotated because the rotation axis of the hugging arm part 20 is inclined with respect to the longitudinal direction of the belly pad part 14, The person 46 can rest at a position where it abuts against the body and back of the person 46, and can support the body so as to hug it well.

  The tip of the horizontal shaft portion 24 is bent along the body of the care recipient 46. Then, a single sheet 28 is stretched and attached to the vertical axis portion 22, the horizontal axis portion 24, and the backrest shaft portion 26.

  The seat 28 has an odd-shaped rectangle, and is provided with locking means such as a hook-and-loop fastener that is wound around and attached to the vertical axis portion 22, the horizontal axis portion 24, and the backrest shaft portion 26. The seat 28 of the hugging arm 20 and the cushion 18 of the belly pad 14 are made of, for example, the same mesh material.

  Each of the hugging arms 20 is provided with an L-shaped handle 30. The handle 30 protrudes beyond the vertical axis 22 on the extension of the horizontal axis 24 and is bent downward in an L shape.

  A plurality of through holes 31 are formed along the shaft 12 in a portion near the lower end portion 12 b of the shaft 12. A grounding member 32 that abuts against the floor surface is provided at the lower end 12 b of the shaft 12. The grounding member 32 is provided with a cylindrical portion 34 into which the lower end portion 12 b of the shaft 12 is inserted, and a pipe 36 fixed to the lower end portion 34 a of the cylindrical portion 34. A through hole communicating with the through hole 31 of the shaft 12 is formed in the cylindrical portion 34, and a height adjusting member 38 is inserted therethrough. Thereby, the through-hole of the cylindrical part 34 is made to correspond to any through-hole 31 of the shaft 12, and it connects with the height adjustment member 38, and the shaft 12 and the grounding member 32 are connected by arbitrary length.

  The pipe 36 is bent in an arc shape located on a vertical plane that intersects the longitudinal direction of the belly pad 14 at a right angle. The lower end portion 34 a of the cylindrical portion 34 is fixed on the arcuate inner peripheral side at a position closer to the end portion 36 a opposite to the direction in which the hugging arm portion 20 protrudes than the center of the pipe 36. A pedal part 42 for stepping used by a caregiver 48 described later is attached to the end 36a of the pipe 36. In the middle of the cylindrical portion 34, a reinforcing rod 40 is obliquely connected and provided at a position near the end portion 36b opposite to the end portion 36a.

  Next, the usage method of the transfer assistance instrument 10 of this embodiment is demonstrated. First, operation | movement of a pair of hugging arm part 20 is demonstrated based on FIG. 5, FIG. The pair of hugging arm portions 20 are rotated around an axis intersecting (θ = 30 °) with respect to the extension line of the abdomen support member 16 by operating the handle 30 to open and close. Thereby, when the caregiver 48 raises the handle 30 by hand as shown in FIG. 5, the tip ends of the pair of hugging arms 20 are opened apart from each other. Further, when the handle 30 is lowered by hand as shown in FIG. 6, the tips of the hugging arm portions 20 approach each other and close. Using this action, the care receiver 46 is held and a transfer operation is performed.

  In this case, as shown in FIG. 3, a cared person 46 sitting on a bed or chair 44 stands up from the chair 44 as shown in FIG. 4 and sits on a wheelchair (not shown) placed near the chair 44. Will be described. First, the caregiver 48 stands with the handle 30 of the transfer assist device 10 in front of the care recipient 46 and points the hugging arm portion 20 of the transfer assist device 10 toward the care receiver 46. Then, the handle 30 is tilted toward the cared person 46, the shaft 12 is tilted, and the hugging arm unit 20 is brought closer to the cared person 46. Next, without changing the position of the shaft 12, the pair of handles 30 are raised as shown in FIG. 5, the hugging arm portion 20 is opened in accordance with the width of the cared person 46, and the arm 12 is inserted under the cared person 46. At the same time, the abdomen 14 is brought into contact with the abdomen of the cared person 46. Thereafter, the handle 30 is lowered so that the width of the hugging arm portion 20 is narrowed, and the handle 30 is lowered obliquely downward and comes into contact with the back of the care receiver 46. Tighten the upper body of 46 with moderate force.

  In this state, the caregiver 48 puts one foot on the pedal member 42 of the pipe 36 of the grounding member 32 and pulls the handle 30 forward while fixing it to the floor. Then, the pipe 36 of the grounding member 32 swings on the floor surface, and a moment about the grounding member 32 is given to the shaft 12 so that the shaft 12 moves. Due to the balance of moments around the floor, the weight of the transfer assist device 10 and the cared person 46 is supported, the cared person 46 is pushed up, and separated from the chair 44. As shown in FIG. It is raised from the chair 44 in a state in which it is fastened to the hugging arm portion 20 and is weighted. Although the care receiver 46 supports the balance in the left-right direction of the transfer assisting device 10 with his / her leg power, the caregiver 48 compensates for the shortage. As a result, the cared person 46 can easily stand up in such a posture as to lean against the transfer assisting device 10 while partially supporting his / her body with his / her foot. Then, the wheelchair or the like (not shown) is caused to stand rearward, and the transfer assisting device 10 is tilted toward the care receiver 46 side. At this time, since the pipe 36 has an arc shape, the entire transfer assisting device 10 rotates so as to roll out in a direction parallel to the median sagittal plane of the care recipient 46, which is an obstacle in transferring to the wheelchair. Can avoid the armrest part.

  When the transfer assisting device 10 is not used, the hugging arm portion 20 is rotated in the direction in which the handle 30 is lowered and folded on the shaft 12 as shown in FIG. Further, the adjusting screw 38 is loosened, and the grounding member 32 is set so that the pipe 36 is parallel to the hugging arm portion 20, and is deeply inserted into the shaft 12 to be shortened so that it can be compactly folded.

  According to the transfer support device 10 of this embodiment, it can be easily used with a simple structure, can reliably assist the transfer work, and has the following effects.

  Since the pair of hugging arms 20 has an L-shape that supports a part of the chest of the care recipient 46 and the heel to the back, the user can perform a transfer operation by hugging the body from behind and right and left. By simply operating the handle 30, the hugging arm 20 tightens the cared person 46 from the chest to the back with an appropriate strength and holds the cared person 46 in a stable state to perform the transfer operation. Can do. Further, when the transfer operation is completed, the handle 30 can be operated to open the hugging arm portion 20 and be easily removed from the cared person 46.

  Since the handle 30 can be used for both the opening and closing of the pair of hugging arms 20 and the change of the inclination of the shaft 12, the pedal 12 is stepped on while holding the handle 30 after the hugging operation. It is convenient that the operation of rotating and holding up by changing the inclination of the can be performed by one operation of pulling the handle 30. Furthermore, the force of the force required for hugging can be used for hugging. When the hugging force is too strong, the pedal member 42 is strongly stepped on to reduce the pulling force of the handle 30, thereby tightening the hugging arm portion 20. Can be adjusted.

  In addition, the transfer assisting device 10 is based on the operation of the caregiver 48 by human power, and the apparatus is small and light, and is portable. Since there is no actuator such as a motor, the price can be kept low. The range of activities of the cared person 46 using the wheelchair can be expanded and the quality of life can be improved. The caregiver 48 can lift the care receiver 46 by lowering the handle 30 downward while pulling the shaft 12 and lifting the care receiver 46, so that his / her weight shift is small and the work posture is improved. It is possible to reduce the weight load on the legs and to support home care and elderly care.

  When the pipe 36 of the grounding member 32 rolls, the shaft 12 moves, and the body 30 of the cared person 46 is pushed forward and upward by moving the hugging arm portion 20 upward with the handle 30 and is lifted away from the chair 46. be able to. When the caregiver 48 raises the cared person 46, the caregiver 48 does not take a posture to slide and can be operated with a natural posture. Furthermore, since the cared person 46 is placed while being tilted forward and rotated, the cared person 46 can be seated, so even in a chair or a wheelchair with an armrest, the armrest does not get in the way and the direction can be changed smoothly. it can. Since the transfer is performed after standing, there is an advantage regardless of the type of wheelchair of the transfer destination.

  In addition, since the cared person 46 supports a part of his / her body weight with his / her foot, by performing pseudo standing transfer, training of the lower limbs is promoted, which has an effect of rehabilitation and care prevention. The care receiver 46 can directly step on the floor and freely move the knee, and can support the body with the care recipient 46's intention. The cared person's 46 waist | hip | lumbar can be put forward and the front body inclination can be increased and it can approach a natural standing state. The cared person 46 must balance the front, rear, left and right of the transfer assisting device 10 in cooperation with the carer 48, and this also has a rehabilitation effect.

  The shaft 12 and the cylindrical portion 34 of the grounding member 32 are connected to the through-hole 31 of the shaft 12 with the adjustment screw 38 so that the through-hole of the cylindrical portion 34 coincides with the through-hole 31 of the shaft 12. It can be adjusted to your height.

  When the transfer assisting device 10 is not used, it can be folded compactly and is not bulky. When used, the adjustment screw 38 is positioned so that the hugging arm portion 20 is positioned near the waist of the care receiver 46. By simply adjusting the height, it can be used immediately, requiring less time for assembly, and can be used continuously.

  In addition, the transfer assistance instrument of this invention is not limited to the said embodiment, Each member can be changed suitably. For example, by using an expansion / contraction element such as a gas spring or a coil spring for the shaft, the compressed spring may be released and easily approximated to the standing posture at the time of transition to the pseudo self-standing state or the pseudo self-standing state after the rising. Further, the shape of the grounding member can be appropriately changed as long as it rolls such as an arc. In the case of a rolling shape, various curve groups such as a parabola, a hyperbola, a cycloid curve, and an involute curve can be assumed in addition to an arc. By providing the bottom surface shape of the ground contact member corresponding to changes in the posture and body position of the cared person standing up, it is also possible to improve the followability to the rising motion. That is, it is possible to arbitrarily give a change in the body position by capturing the bottom surface shape as a cam curve and the body position (mainly waist) of the cared person as the output of the follower. As the grounding member, a caster or the like may be used in addition to the pipe. When casters are used, it is possible to move in the same posture. A knee pad may be provided on the shaft to disperse the weight of the cared person. By placing the caregiver's knee on the knee pad, the burden on the caregiver's feet can be reduced.
