Description

本発明は、腋下および膝下を支持した被介助者を吊上げて例えば車椅子とベッドの間で移乗させる移乗介助装置に関するものである。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer assistance device that lifts a person supported by the armpits and below the knees and transfers the person, for example, between a wheelchair and a bed.

従来、この種の移乗介助装置としては、例えば下記の特許文献1に記載されているものが知られている。その移乗介助装置は、腋下を支える腋支持部材と、膝下を支える膝支持部材とをそれぞれの上端部で一つに纏め、この纏め部分をリフトで移動用レールに吊り下げ、腋と膝を一体的に吊上げて被介助者を移送するものである。 Conventionally, as this type of transfer assistance device, for example, one described in Patent Document 1 below is known. In the transfer assistance device, an armpit support member that supports the armpit and a knee support member that supports the knee are combined at their upper ends, and this combined portion is suspended from a moving rail by a lift, and the armpit and the knee are supported. It transports the person being assisted by integrally lifting it.

ところが、上記した従来の移乗介助装置においては、腋支持部材および膝支持部材はひとつに纏めて吊下げられているので、一か所の吊下げ位置を中心に前後左右に揺れて円錐状の歳差状揺動をしやすい。このような歳差状揺動は、吊上げられた被介助者を不安にさせ安定感を阻害する。また、膝支持部材と腋支持部材は一体同時に昇降駆動されるので、吊上げた状態で被介助者の姿勢を変えることはできない。従って、座った姿勢で吊上げられた被介助者は座った姿勢のままで移送されるし、寝た姿勢で吊上げられた被介助者は寝た姿勢のまま移送されるしかなかったのである。すなわち、被介助者を車椅子とベッドとの間で移送する場合に、その移送途中で被介助者の姿勢を変えられなかったので、車椅子とベッド間の移乗に多大な労力と手間を必要としたのである。 However, in the above-described conventional transfer assistance device, the armpit support member and the knee support member are hung together, so that they sway back and forth and left and right around a single hanging position, resulting in a conical age. Easy to oscillate differentially. Such precessional rocking makes the person being assisted who is lifted uneasy and impedes a sense of stability. In addition, since the knee support member and the armpit support member are driven up and down at the same time, it is impossible to change the posture of the person being assisted while being lifted. Therefore, a person to be assisted who is lifted in a sitting posture is transported in a sitting posture, and a person to be assisted who is lifted in a lying posture has to be transported in a lying posture. In other words, when the person being assisted is transferred between the wheelchair and the bed, the person being assisted cannot change their posture during the transfer, requiring a great deal of labor and time to transfer between the wheelchair and the bed. of.

本発明は、上記した従来の問題点に鑑みてなされたものであって、被介助者を揺らさず安定に吊上げるとともに、吊上げた状態で被介助者の姿勢を変えることのできる移乗介助装置の提供を目的とする。 SUMMARY OF THE INVENTION The present invention has been made in view of the conventional problems described above, and provides a transfer assistance device that can stably lift a person being assisted without shaking the person being assisted and can change the posture of the person being assisted while being lifted. for the purpose of providing

上記目的を達成するために、本発明に係る移乗介助装置は、起立状態で床に置かれる柱体と、柱体の上部に前向きに突設された横梁体と、横梁体に水平旋回自在に枢支された旋回棒と、旋回棒の一端部に吊下げられて被介助者の腋下を支える腋支持部材と、旋回棒の他端部に吊下げられて被介助者の膝下を支える膝支持部材と、腋支持部材を昇降させる腋昇降機構と、腋昇降機構とは独立に膝支持部材を昇降させる膝昇降機構と、を備えて成り、旋回棒において腋支持部材を吊下げる一端部の第1吊下げ位置と膝支持部材を吊下げる他端部の第2吊下げ位置とが水平方向に離間して配置され、横梁体による旋回棒の枢支位置が旋回棒における第1吊下げ位置と第2吊下げ位置との間に配置されていて、腋支持部材が、旋回棒の第1吊下げ位置に吊り下げられる条体と、条体に取り付けられて被介助者の腋下に装着されるベルト体と、を備えて成り、ベルト体が、被介助者の上腕の内側を通されて腋下に装着される帯部と、帯部に固定されていて被介助者の腋下への帯部の装着時に被介助者の頸部ないし頭部を載せて支持可能な剛性を有する支持板部と、を備えて成ることを特徴とする構成にしてある。 In order to achieve the above object, a transfer assistance device according to the present invention comprises a pillar placed on the floor in an upright state, a lateral beam projecting forward from the top of the pillar, and a horizontal rotatable movement on the lateral beam. A swivel rod that is pivotally supported, an armpit support member suspended from one end of the swivel rod to support the underarm of the care receiver, and a knee suspended from the other end of the swivel rod to support the knee of the care receiver. A support member, an armpit elevating mechanism for elevating the armpit support member, and a knee elevating mechanism for elevating the knee support member independently of the armpit elevating mechanism. The first suspension position and the second suspension position at the other end from which the knee support member is suspended are horizontally spaced apart, and the pivotal support position of the swivel bar by the lateral beam body is the first suspension position on the swivel bar. and a second suspension position, and the armpit support member has a string suspended at the first suspension position of the swivel rod, and a string mounted on the string and attached to the underarm of the person being assisted. a belt body, wherein the belt body is passed through the inside of the upper arm of the person being assisted and is worn under the armpit; and a support plate portion having a rigidity capable of supporting the neck or head of the person being assisted when the belt portion is worn.

また、前記構成において、腋支持部材の支持板部は、帯部の帯長手方向に沿うように長く形成された基部と、基部の帯長手方向略中央部から上方に延在して被介助者の頸部ないし頭部を載せる受部と、から成り、基部が帯長手方向に離間した複数個所で帯部に固定されていることを特徴とするものである。Further, in the above configuration, the support plate portion of the armpit support member includes a base portion elongated along the longitudinal direction of the band portion, and an approximately center portion of the base portion in the longitudinal direction of the band extending upward from the base portion to support the person being assisted. and a receiving portion on which the neck or head of the belt is placed.

また、前記した各構成において、旋回棒における第1吊下げ位置と第2吊下げ位置の間の距離が、被介助者の膝下と腋下の間の距離よりも大きく設定されていることを特徴とするものである Further, in each of the above configurations, the distance between the first suspension position and the second suspension position on the swivel bar is set larger than the distance between the knee and armpit of the person being assisted. and

本発明に係る移乗介助装置によれば、旋回棒における腋支持部材と膝支持部材の吊下げ位置が離間した2か所であり、横梁体による旋回棒の枢支位置が旋回棒の第1吊下げ位置と第2吊下げ位置との間に配置されているので、あたかも天秤棒状の支持形態を採ることができる。従って、腋支持部材と膝支持部材とがひとつに纏められて吊下げられる従来技術のように腋支持部材および膝支持部材が一か所の吊下げ位置を中心として大きく揺動したり歳差運動をしたりするといったことがなく、この移乗介助装置は安定な吊下げ状態を維持できる。また、膝支持部材が腋支持部材とは別個独立に昇降駆動されるので、吊上げた状態の被介助者の姿勢変更、すなわち座った姿勢の被介助者を吊上げたのちに膝だけを持ち上げて体全体を寝かせた姿勢に変えるといったことができ、その寝かせた姿勢で移送できる。無論、寝た姿勢から座った姿勢へと逆の姿勢変更も可能である。 According to the transfer assistance device of the present invention, the suspension positions of the armpit support member and the knee support member on the swivel bar are separated from each other at two positions, and the swivel bar is pivotally supported by the lateral beam body at the first suspension position of the swivel bar. Since it is arranged between the hanging position and the second hanging position, it is possible to adopt a supporting form as if it were a balance bar. Therefore, unlike the prior art in which the armpit support member and the knee support member are hung together, the armpit support member and the knee support member swing largely around a single suspension position or precession. This transfer assistance device can maintain a stable suspended state without the need to move the person. In addition, since the knee support member is driven up and down independently of the armpit support member, it is possible to change the posture of the person being assisted while being lifted. It is possible to change the posture of the whole to lie down, and it is possible to transfer it in that lying posture. Of course, it is also possible to change the posture from the sleeping posture to the sitting posture.

また、旋回棒における第1吊下げ位置と第2吊下げ位置の間の距離が、被介助者の膝下と腋下の間の距離よりも大きく設定されているものでは、腋支持部材と膝支持部材とによる被介助者の吊上げ態様が側面から視て略逆さ台形状になるから、吊上げられた被介助者が前後左右に歳差状揺動をしにくくなって安定した状態に保たれ、被介助者に安心感を与える。これにより、吊上げた被介助者を所望降下位置の上方に正確に位置決めしやすくなり、所望位置に確実に降ろすことができる。 In addition, when the distance between the first suspension position and the second suspension position on the swivel bar is set to be larger than the distance between the knee and the armpit of the person being assisted, the armpit support member and the knee support When viewed from the side, the person being assisted is lifted up in a substantially inverted trapezoidal shape. Give the caregiver a sense of security. As a result, the person being assisted who has been lifted can be accurately positioned above the desired lowering position, and can be reliably lowered to the desired position.

そして、支持部材のベルト体に支持板部が付設されているので、被介助者の腋下へのベルト体の装着時に、支持板部が被介助者の頸部ないし頭部を載せて支持することができる。従って、体力が弱っている被介助者であっても、吊上げ時に頭部がその重みで後向きに垂れ下がることを防ぎ、安全且つ安心に移送することができる Since the support plate portion is attached to the belt body of the armpit support member , the support plate portion supports the neck or head of the person being assisted when the belt member is attached to the armpit of the person being assisted. can do. Therefore, even if the person to be assisted is weak in physical strength, the head can be prevented from sagging backward due to the weight of the person being lifted, and the person can be transported safely and securely .

そして、固定柱5の上端部5A近傍には、ワイヤーウインチなど手動式の昇降駆動機41の本体ケーシングが固定用金具40を介して取り付けられている。この昇降駆動機41では、一端が垂下杆8下端の輪部43につながれたワイヤー39が、手動レバー42の手動の揺動動作により本体ケーシング内の駆動ロールに巻き上げられるようになっている。この昇降駆動機41でも、昇方向と降方向の切り替えは、本体ケーシングに設けられた切り替えレバーの操作による。前記したようなワイヤー39の巻き上げ操作により、垂下杆8、横梁体7、移動柱6、前端梁9、支持部材10、受板部材11、軸受部12および旋回棒13が一体的に持ち上げられるのである。すなわち、前記の垂下杆8、横梁体7、移動柱6、軸受部12、旋回棒13、ワイヤー39および昇降駆動機41から成る構成が、腋支持部材14を昇降させる腋昇降機構16の構成である。
The lifting drive mechanism 34 constitutes the knee lifting mechanism 17, and the chain 29, which is wound around the drive gear in the main body casing, is moved in and out of the main body casing by the manual swinging operation of the manual lever 35. is designed to be raised and lowered. Switching between the ascending direction and descending direction of the chain 29 is performed by operating a switching lever provided on the main body casing.
In the vicinity of the upper end portion 5A of the fixed column 5, a body casing of a manual lift driving device 41 such as a wire winch is attached via a fixing metal fitting 40. As shown in FIG. In this lifting drive 41, a wire 39, one end of which is connected to a loop 43 at the lower end of the hanging rod 8, is wound up by a drive roll in the main body casing by manually swinging a manual lever 42. As shown in FIG. In this elevator driving machine 41 as well, switching between the ascending direction and the descending direction is performed by operating a switching lever provided on the main body casing. By winding up the wire 39 as described above, the hanging rod 8, the cross beam body 7, the moving post 6, the front end beam 9, the support member 10, the receiving plate member 11, the bearing portion 12 and the swivel rod 13 are integrally lifted. be. That is, the structure comprising the hanging rod 8, the horizontal beam body 7, the moving column 6, the bearing portion 12, the swivel rod 13, the wire 39, and the lifting drive 41 is the structure of the armpit lifting mechanism 16 for lifting and lowering the armpit support member 14. be.

上記のように構成された移乗介助装置1の作用を次に説明する。図6に示すように、例えば車椅子Sに乗った被介助者Mに対し、腋支持部材14のベルト体22を腋下に装着したのち、昇降駆動機41の手動レバー42を揺動操作し腋昇降機構16の全体構成を少し引き上げて(矢印U方向)条体28を展張させ、ベルト体22の帯部23を腋下に密着させる。すると、ベルト体22の支持板部25が頭部Hを後方からしっかり支持する。続いて、膝支持部材15のベルト体30を被介助者Mの膝下に装着し、昇降駆動機34の手動レバー35を手で揺動させてチェーン29を引き上げる(矢印P方向)。 Next, the operation of the transfer assistance device 1 configured as described above will be described. As shown in FIG. 6, after the belt member 22 of the armpit support member 14 is worn under the armpit of a person M who is being assisted on a wheelchair S, for example, the manual lever 42 of the lifting/lowering drive unit 41 is operated to swing the armpit. The overall configuration of the lifting mechanism 16 is slightly raised (in the direction of arrow U) to extend the strip 28 and bring the band 23 of the belt 22 into close contact with the armpit. Then, the support plate portion 25 of the belt body 22 firmly supports the head H from behind. Subsequently, the belt body 30 of the knee support member 15 is worn under the knee of the person being assisted M, and the manual lever 35 of the lift drive 34 is swung by hand to pull up the chain 29 (in the direction of arrow P).

そうして、図7に示すように、被介助者Mの膝下を腋下の高さもしくは腋下以上に持ち上げると(矢印V方向)、被介助者Mは寝た姿勢になる。このとき、第1吊下げ位置13Aと第2吊下げ位置13Bの間の距離Kは腋と膝の間の距離K1よりもはるかに大きい。従って、腋支持部材14と膝支持部材15とによる被介助者Mの吊上げ態様が側面から視て略逆さ台形状になる。これにより、吊上げられた被介助者Mは前後左右への歳差状揺動がしにくくなり安定な状態に保たれる。その結果、吊上げた被介助者Mに安心感を与えるとともに、被介助者Mを所望位置に正確に位置決めしやすくなり、その所望位置に確実に降ろすことができる。 Then, as shown in FIG. 7, when the knee of the person being assisted M is lifted to the height of the armpit or above the armpit (in the direction of arrow V), the person being assisted M assumes a lying posture. At this time, the distance K between the first suspension position 13A and the second suspension position 13B is much larger than the distance K1 between the armpit and the knee. Therefore, the manner in which the person being assisted M is lifted by the armpit support member 14 and the knee support member 15 has a substantially inverted trapezoidal shape when viewed from the side. As a result, the person to be assisted M who is lifted up is less likely to precessively oscillate forward, backward, left and right, and is kept in a stable state. As a result, the person being assisted M who has been lifted can be given a sense of security, and the person being assisted M can be accurately positioned at a desired position with ease, and can be reliably lowered to the desired position.

前記のように被介助者Mを吊上げた移乗介助装置1は、図8に示すように、操作者により前方(矢印F方向)に押されて、脚部3の脚先端部3CがベッドBのベッド下隙間BAに挿入される。このとき、被介助者MはベッドBの長手方向と直角の向きでベッドBの上方位置にある。この状態から、操作者は手で旋回棒13などを持って軸受部12の軸心C回り例えば平面視時計回り方向(矢印R方向)に略90度旋回させる。 As shown in FIG. 8, the transfer assistance device 1, which has lifted up the person M as described above, is pushed forward (in the direction of arrow F) by the operator, and the leg tips 3C of the legs 3 reach the bed B. It is inserted into the gap BA under the bed. At this time, the person being assisted M is positioned above the bed B in a direction perpendicular to the longitudinal direction of the bed. From this state, the operator holds the turning rod 13 or the like by hand and turns the shaft center C of the bearing portion 12 by about 90 degrees, for example, clockwise in a plan view (in the direction of arrow R).

すると、被介助者Mは、図9に示すように、吊下げられた状態でベッドBの長手方向と平行の向きになる。その後、操作者は、昇降駆動機41を操作しワイヤー39を繰り出させてベルト体22を含む腋昇降機構16全体を降下させる(図10中の矢印D方向)。これにより、被介助者Mの臀部がベッドB上に着床し、次いで腰、背中、頭部Hと順次着床していく。更に、操作者は、昇降駆動機34を操作しチェーン29を繰り出させてベルト体30を降下させる。これにより、被介助者Mの踵がベッドB上に着床して脚が延び、図10に示すように、膝下が着床する。このとき、横梁体7は固定柱5の上端部5A近くまで降下している。
一方、ベッドB上に寝ている被介助者Mを車椅子Sに移乗させる場合は、図10に示した状態から逆の手順で、図9、図8、図7を順次経て、図6に示した状態まで持って行き、被介助者Mから腋支持部材14と膝支持部材15を取り外せばよい。
Then, as shown in FIG. 9, the person being assisted M is oriented parallel to the longitudinal direction of the bed B in a suspended state. After that, the operator operates the lift driving device 41 to extend the wire 39 and lower the entire armpit lifting mechanism 16 including the belt body 22 (in the direction of arrow D in FIG. 10). As a result, the buttocks of the person being assisted M land on the bed B, and then the waist, back, and head H land on the bed in this order. Further, the operator operates the lift drive device 34 to let out the chain 29 and lower the belt body 30 . As a result, the heel of the person being assisted M lands on the bed B, the leg extends, and as shown in FIG. 10, the bottom of the knee lands on the bed. At this time, the horizontal beam body 7 is lowered to near the upper end portion 5A of the fixed column 5. As shown in FIG.
On the other hand, when transferring the person to be assisted M lying on the bed B to the wheelchair S, the procedure shown in FIG. The armpit support member 14 and the knee support member 15 can be removed from the person M to be assisted.

上記したように、この実施形態の移乗介助装置1によれば、腋支持部材14と膝支持部材15の吊下げ位置13A,13Bが離間した2か所であるから、腋支持部材と膝支持部材とがひとつに纏められて吊下げられる従来技術のように腋支持部材および膝支持部材が吊下げ位置を中心として大きく揺動したり歳差運動をしたりするといったことがなく、安定した吊下げ状態に保持でき被介助者Mに安心感を与える。また、膝支持部材14が腋支持部材15とは別個独立に昇降駆動されるので、吊上げた状態の被介助者Mの姿勢変更、すなわち座った姿勢の被介助者Mを吊上げたのちに膝だけを持ち上げて体全体を寝かせた姿勢に変えるといったことができ、その寝かせた姿勢で移送することができる。 As described above, according to the transfer assistance device 1 of this embodiment, since the suspension positions 13A and 13B of the armpit support member 14 and the knee support member 15 are separated from each other, the armpit support member and the knee support member Stable suspension without swinging or precessing the armpit support member and the knee support member around the suspension position unlike the conventional technology in which the armpit support member and the knee support member are suspended together. The state can be maintained, and the person being assisted M is given a sense of security. In addition, since the knee support member 14 is driven up and down independently of the armpit support member 15, the posture of the person being assisted M in a lifted state can be changed. can be lifted to change the entire body into a lying position, and can be transported in that lying position.

また、腋支持部材のベルト体22には支持板部25が付設されているので、被介助者Mの腋下へのベルト体22の装着時に、支持板部25が被介助者Mの頸部Nおよび頭部Hを載せて後方から支持することができる。これにより、体力が弱っている被介助者Mであっても、吊上げ時に頭部Hがその重みで後向きに垂れ下がるといったことを防ぐことができ、安全に移送できる。 Further, since the support plate portion 25 is attached to the belt body 22 of the armpit support member, when the belt body 22 is attached to the underarm of the person being assisted M, the support plate portion 25 is placed on the neck of the person being assisted M. N and head H can be put on and supported from behind. As a result, even the person being assisted M whose physical strength is weakened can be safely transported by preventing the head H from hanging backward due to the weight of the person being assisted when being lifted.

そして、柱体2の脚部3は車椅子Sを導入可能な前方開口3Aを有しているので、その前方開口3Aから脚部3内の収容空間3Bに車椅子Sを導入することができる。従って、横梁体7や旋回棒13の下方位置において、被介助者Mに対する各支持部材14,15の装着作業や吊上げ作業を楽に行なうことができる。また、脚先端部3Cがベッド下隙間BAに挿入可能な大きさおよび厚さに形成されているので、被介助者Mの吊上げ後は装置1全体を移動させて脚先端部3Cをベッド下隙間BAに挿入できるから、吊上げたままの被介助者MをベッドBの上方位置に確実に移動させることができる。 Since the leg portion 3 of the column 2 has a front opening 3A into which the wheelchair S can be introduced, the wheelchair S can be introduced into the accommodation space 3B in the leg portion 3 through the front opening 3A. Accordingly, the support members 14 and 15 can be attached to and lifted from the person being assisted M at the position below the lateral beam 7 and the swivel rod 13 with ease. In addition, since the leg distal end portion 3C is formed to have a size and thickness that can be inserted into the under-bed gap BA, after the person being assisted M is lifted, the entire apparatus 1 is moved to move the leg distal end portion 3C into the under-bed gap. Since it can be inserted into the BA, it is possible to reliably move the person to be assisted M who is being lifted to a position above the bed B.

そうして、この移乗介助装置1は、腋昇降機構16および膝昇降機構17がいずれも手動式の昇降駆動器具34,41を備えているので、製品コストが安価で済み電源などの外部動力が不要であるから、極めて安価で汎用性の高い装置を提供できたのである。 Since the armpit lifting mechanism 16 and the knee lifting mechanism 17 are both provided with the manual lifting drive devices 34 and 41, the transfer assistance device 1 can be manufactured at a low cost and requires no external power such as a power source. Since it is not necessary, it was possible to provide an extremely inexpensive and highly versatile device.

尚、上記の実施形態では、ベルト体に付設される支持板部として、被介助者Mの頸部Nおよび頭部Hの双方を載せて支持する支持板部25を例示したが、本発明はそれに限定されるものでない。例えば、頭部Hまでは届かないが頸部Nのみを載せて支持するような支持板部であっても構わない。
また、上記では、柱体の脚部として平面視でコの字状の脚部3を例示したが、本発明の脚部としては、平面視でUの字状またはVの字状などの形態のものであってもよい。
そして、上記では、ベルト体22側の昇降駆動機41としてワイヤー39利用のワイヤーウインチを用い、ベルト体30側の昇降駆動機34としてチェーン29利用のレバーホイストを用いた例を示している。しかしながら、これらを逆に組み替えて、ベルト体22側にレバーホイストを用いベルト体30側にワイヤーウインチを用いるようにしても構わない。あるいは、昇降駆動機41,34は腋昇降機構および膝腋昇降機構の構成要素として手動式のものを用いているが、これらは手動式に限られるものでなく、例えば電動式の昇降駆動機を用いることもできる。
In the above-described embodiment, the support plate portion 25 on which both the neck N and the head H of the person being assisted M are placed and supported is illustrated as the support plate portion attached to the belt body. It is not limited to this. For example, it may be a support plate that does not reach the head H but supports only the neck N on it.
In the above description, the U-shaped leg 3 in plan view was exemplified as the leg of the column. may be of
In the above example, the wire winch using the wire 39 is used as the lifting drive device 41 on the belt body 22 side, and the lever hoist using the chain 29 is used as the lifting drive device 34 on the belt body 30 side. However, these may be rearranged in reverse so that the lever hoist is used on the belt body 22 side and the wire winch is used on the belt body 30 side. Alternatively, the lift drivers 41 and 34 are manually operated as components of the armpit lift mechanism and the knee-armpit lift mechanism, but these are not limited to manual lift drives, and for example, electric lift drivers may be used. can also be used.

そして、本発明は、上記した諸々の実施形態に限定されるものでない。すなわち、本発明の分野における通常の知識を有する者であれば想到し得る、各種変形、修正を含む、本発明の要旨を逸脱しない範囲の設計変更があっても、本発明に含まれることは言うまでもない。 And, the present invention is not limited to the various embodiments described above. That is, the present invention does not include any design changes that do not depart from the gist of the present invention, including various modifications and modifications that a person having ordinary knowledge in the field of the present invention can conceive.
