Description

発明の詳細な説明Detailed Description of the Invention

本発明は、被介護者をベッドからストレッチャーに又はストレッチャーからベッドに移載することを目的としてストレッチャーに設けられたシフトするシートの構造に関する。  The present invention relates to a structure of a shift sheet provided on a stretcher for the purpose of transferring a cared person from a bed to a stretcher or from a stretcher to a bed.

従来のシフトするボードを備えたストレッチャーにおいては、被介護者をベッドからストレッチャーへ又はストレッチャーからベッドへ移載する際に、ベッド面とベッド上に展開するストレッチャー面との間に生じる段差が大きく、そのため、被介護者に苦痛を与えることなく段差を通過し得るよう剛性の高いボードが用いられてきた。  In a stretcher having a conventional shifting board, when a care recipient is transferred from a bed to a stretcher or from a stretcher to a bed, it occurs between the bed surface and the stretcher surface deployed on the bed. Steps are large and, therefore, boards with high rigidity have been used so that they can pass through the steps without causing pain to the care recipient.

剛性を減じた柔軟性を有するボードを用いる場合は、ボードに適度の厚みを持たせて、段差によって生じる通過角度や凹凸の緩和など、被介護者が受ける境界通過の際の不快感の緩和に努めている。  When using a board with flexibility with reduced rigidity, give the board an appropriate thickness to relieve discomfort when passing the boundary, such as the passage angle and unevenness caused by steps. I'm trying.

また、移載用のボードに替えて薄いプラスチックシートなどを用いる場合は、シートを収容するストレッチャーの構造体を極力薄くして、ベッド上に展開する段差を縮小することが行われており、(例えば、特願平9−260785号公報)すでに段差の縮小という点では、一応満足し得る程度まで実現し得ているものもある。  In addition, when using a thin plastic sheet or the like instead of the transfer board, the structure of the stretcher that accommodates the sheet is made as thin as possible to reduce the step developed on the bed, (For example, Japanese Patent Application No. 9-260785) In terms of reducing the level difference, there are some that have been realized to the extent that they can be satisfied.

ボードやシートは、キャリッジによってストレッチャー本体から繰出され、ベッド上に展開する。また、逆にベッド上に展開したボードやシートはキャリッジによって本体に繰込まれる。すなわちストレッチャーに装備されたキャリッジに牽引されシフトすることによって移載を達成することができるものである。  Boards and sheets are unwound from the stretcher body by the carriage and spread on the bed. Conversely, the board or sheet developed on the bed is fed into the main body by the carriage. That is, transfer can be achieved by being pulled and shifted by a carriage mounted on the stretcher.

一方、移載を終えて次にストレッチャーを車いすの姿勢に変換するとき、ボードはストレッチャーのキャリッジに締結されていて、ストレッチャーの起伏に伴いボードも屈曲して車いすの形態に変換されるが、これらの個々の機能動作は動力化されても、シートやフットレストなどの形態への対応は、手作業によるものとされている。  On the other hand, when the transfer is finished and the stretcher is converted into a wheelchair posture next time, the board is fastened to the carriage of the stretcher, and the board is bent and converted into a wheelchair shape as the stretcher undulates. However, even if these individual functional operations are motorized, the correspondence to the form such as the seat and the footrest is assumed to be manual.

発明が解決しようとする課題Problems to be solved by the invention

本来、ストレッチャーとベッドとの段差は小さいほど好ましく、また、ボードはその限りにおいて薄いものであることが好ましい。  Originally, it is preferable that the level difference between the stretcher and the bed is as small as possible, and it is preferable that the board is as thin as possible.

すでに十分に段差の縮小された薄型の構造体と薄型のスライドシートを有するストレッチャーであっても、被介護者が横臥するベッドの面は、肩や腰と接触する部分の沈み量が比較的大きく、シート上に被介護者を収容するとき、被介護者にシートが接触する際の接触感が、柔らかく均等で滑らかに移行することが望まれる。  Even with a stretcher that already has a thin structure with a sufficiently reduced step and a thin slide sheet, the bed surface on which the cared person lies is relatively sinking at the part that contacts the shoulder and waist. Largely, when accommodating a cared person on a sheet, it is desired that the feeling of contact when the sheet contacts the cared person is soft, uniform, and smooth.

すなわち、シートをベッド上に展開したときには、ベッド面の変形と相俟って、シートは相応の撓み変形を許容し得るものであることが望ましい。  That is, when the sheet is developed on the bed, it is desirable that the sheet can be allowed to undergo a corresponding deformation due to the deformation of the bed surface.

一方、シートはキャリッジに締結されてシフトする駆動力に耐える強度と剛性を有するものでなければならないと同時に、起伏等の構造体の屈曲に合せて屈曲を繰り返すことに耐えることが必要とされる。  On the other hand, the sheet must be strong and rigid enough to withstand the driving force that is fastened to the carriage and shifted, and at the same time, it is required to withstand repeated bending according to the bending of the structure such as undulations. .

また、ストレッチャーから車いすに形態変換した後、被介護者が床面に足を着けて起立するなど、車いすの状態としてのストレッチャーから被介護者が離れて行く場合(例えば他の車いすに乗り換える場合など)と、そのまま車いす状態のストレッチャーに座位の姿勢で留まる場合とがある。すなわち、前者の場合では、或いは必要に応じて、フットレストは脚部のシートと共に座面下に収納されるか、或いは除去されねばならないことであり、後者の場合すなわち座位の姿勢で車いすの形態のストレッチャーに留まる場合には、フットレストは予め車いすの状態に装備されていることが望まれる。すなわち形態変換動作は完結的に行われることが望ましい。  In addition, when the cared person goes away from the stretcher as a wheelchair, such as when the cared person stands on the floor after changing the form from a stretcher to a wheelchair (for example, change to another wheelchair) In some cases) and may remain seated on a wheelchair stretcher. That is, in the former case, or if necessary, the footrest must be stored under the seat with the seat of the leg or removed, and in the latter case, that is, in the form of a wheelchair in the sitting position. In order to stay on the stretcher, it is desirable that the footrest is equipped in a wheelchair state in advance. That is, it is desirable that the form conversion operation is performed completely.

課題を解決するための手段Means for solving the problem

上記目的を達成するために、本発明のストレッチャーにおいては、シートはベッド面やストレッチャ−の支持面上を滑り易く、かつベッド面の凹凸に対して適度に追随変形し得る可撓性を有するプラスチックなどの薄板を用いてキャリッジと締結され、キャリッジはプラットフォームの案内溝に沿って駆動される。  In order to achieve the above object, in the stretcher of the present invention, the sheet is slidable on the bed surface or the support surface of the stretcher, and has flexibility that can be appropriately deformed with respect to the unevenness of the bed surface. A thin plate such as plastic is used to fasten the carriage, and the carriage is driven along the guide groove of the platform.

また、ベッドの端部に横臥する被介護者に対し、最初にシートが接触する部分(ベッドに対して向い合う縁辺)を緩やかな波型などとして、ベッド面の凹凸に馴染み易い撓みが得られるよう成型している。  In addition, for the cared person lying on the edge of the bed, the first contact with the sheet (the edge facing the bed) can be made into a gentle corrugation, etc., so that it is easy to adjust to the unevenness of the bed surface. It is shaped like this.

ストレッチャー本体の構造体と一体となって屈曲するシートの屈曲部は蝶番構造とし、蝶番にはプラスチック素材の成型による長蝶番(心材はステンレス線材)を用いて接合・成形し、キャリッジの推力にも対応すると共に、可撓性を有するものを用いる。  The bent part of the sheet that bends together with the structure of the stretcher body has a hinge structure, and the hinge is joined and molded using a long hinge made of plastic material (the core material is a stainless steel wire), which is used for the thrust of the carriage. And a flexible one is used.

さらに、互いにシートを蝶番で連結することによって、多数のシートをW型に折畳むことが可能であることから、フットレストの回転に伴って、脚部のシートをプラットフォームの下部に折曲げて収納することが可能なものとする。  Furthermore, by connecting the seats to each other with a hinge, it is possible to fold a large number of seats into a W-shape, so that the leg seats are folded and stored at the bottom of the platform as the footrest rotates. Be possible.

発明の実施の形態を実施例に基き、図面を参照して説明する。なお、以下においては、車いす型ストレッチャーを説明の便宜上介助機と称する場合がある。
図1において、介助機のプラットフォーム3a、3b、3cにはそれぞれキャリッジ4a、4b、4cが設けられていて、キャリッジ4a、4b、4cはそれぞれシート1a、1b、1cと締結されており、キャリッジに牽引されてシートはシフトすることができる。ただし、キャリッジ4cには牽引機能は設けていない。
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to the drawings. In the following description, the wheelchair type stretcher may be referred to as an assisting device for convenience of explanation.
In FIG. 1, the platforms 3a, 3b, and 3c of the assisting machines are provided with carriages 4a, 4b, and 4c, respectively. The carriages 4a, 4b, and 4c are fastened to the sheets 1a, 1b, and 1c, respectively. When pulled, the seat can shift. However, the carriage 4c has no traction function.

すなわち、キャリッジ4a、4bはプラットフォーム内に設けられたワイヤロープ若しくはベルトなどの牽引体によって、シートを図1の状態から図2の状態に、又は図2の状態から図1の状態にシフトすることが可能な構造になっている。  That is, the carriages 4a and 4b shift the sheet from the state shown in FIG. 1 to the state shown in FIG. 2, or from the state shown in FIG. 2 to the state shown in FIG. The structure is possible.

プラットフォーム3a、3b、3cは、介助機本体の昇降動作によって、ベッド面に接着し、被介護者の受け渡しを行う。  The platforms 3a, 3b, and 3c are bonded to the bed surface by the lifting and lowering operation of the assisting device main body, and deliver the cared person.

被介護者を横臥させた状態でプラットフォーム3をベッド上に接着し、キャリッジ4によってシート1をベッド上に繰出して(図2)、緩やかな波形に成型したシートの先端部分6を被介護者の下に敷き込み、つぎに被介護者を横転仰臥させてシート上に乗移らせ、シートをプラットフォーム上に収容して移載を完了する(図1)。  The platform 3 is adhered on the bed while the cared person is lying down, the sheet 1 is fed out onto the bed by the carriage 4 (FIG. 2), and the leading end portion 6 of the sheet molded into a gentle waveform is attached to the cared person. Lay down, then turn the cared person upside down and transfer onto the seat, and the seat is placed on the platform to complete the transfer (FIG. 1).

ストレッチャーが車いすの状態に変換される際には、シート1aはプラットフォーム3aと一体となって起伏し、またシート1cはプラットフォーム3cと一体になって俯仰する(図5の状態)。シート1は、シート1a、1b、1x、1y、1cとそれらを連結する可撓性を有する蝶番2a、2b、2x、2yとから成っている。  When the stretcher is converted into a wheelchair state, the seat 1a is raised and lowered integrally with the platform 3a, and the seat 1c is lifted together with the platform 3c (state shown in FIG. 5). The sheet 1 includes sheets 1a, 1b, 1x, 1y, and 1c and hinges 2a, 2b, 2x, and 2y having flexibility for connecting them.

ストレッチャーが車いすの状態(図5の状態、介助機としての一形態)にあるときは、被介護者は介助機から降りて床面に足を着けて立ち上がることができ、他の車いすへ移乗するなど介助機を離れる行動をとることができる。  When the stretcher is in a wheelchair (the state shown in FIG. 5, one form of assistance machine), the cared person can get off the assistance machine and stand up on the floor and transfer to another wheelchair. You can take action to leave the assistive device.

また、ストレッチャーが車いすの状態に変換され、車いすとして被介護者が乗ったまま移動するなどの場合には、プラットフォーム3cを俯下させるに先立って、前以てフットレスト5を図3の状態から3/4回転して図6の形態に整えておくことが必要である。  When the stretcher is converted into a wheelchair and the cared person moves as a wheelchair, the footrest 5 is moved from the state shown in FIG. 3 before the platform 3c is lowered. It is necessary to arrange it in the form of FIG. 6 by rotating 3/4.

発明の効果The invention's effect

被介護者をベッドからストレッチャーに移載する際の被介護者が受ける違和感を緩和し、また、移載や姿勢の変換を行う際の介助者の作業の省力化に資することができる。すなわち、ストレッチャーの移載機能の質の向上と作業の省力化と効率化を推進することができる。  It is possible to alleviate the uncomfortable feeling experienced by the cared person when transferring the cared person from the bed to the stretcher, and to contribute to the labor saving of the assistant's work when transferring or changing the posture. That is, improvement in the quality of the transfer function of the stretcher and labor saving and efficiency of work can be promoted.

さらに、ストレッチャーから車いすへの変換が自動的になし得るなど、全ての機能動作が電動化され得ることからことから、被介護者自らが介助機を操作・運行することが可能となる。  Furthermore, since all functional operations can be motorized, for example, conversion from a stretcher to a wheelchair can be performed automatically, the care recipient can operate and operate the assisting device himself / herself.
