Abstract
Description
本発明は、車椅子の利用者の血流促進を計ると共に各種血栓予防及び健康の増進が計れるように工夫した血流促進及び血栓予防機能付車椅子に関するものである。 The present invention relates to a wheelchair with a blood flow promotion and thrombus prevention function that is designed to measure the blood flow of a wheelchair user and to prevent various blood clots and improve health.
従来の車椅子は、歩行が困難な方の移動のみを目的とした構造になっていた。 Conventional wheelchairs have a structure intended only for movement of people who have difficulty walking.
従来の車椅子は、車椅子に乗車しているときに、血流の促進と各種血栓の予防及び健康の増進が計れなかった。 Conventional wheelchairs cannot promote blood flow, prevent various blood clots, and improve their health when they are in the wheelchair.
車椅子本体（１）に電動モーター（２）と該電動モーターの電源とするバッテリー（５）と該バッテリーの充電器（６）を該車椅子本体に設置する堅牢な台（１２）を設けて固定し、該電動モーターの回転軸の両端に変心カム（４）を軸設し、該変心カムの他端の一方は足台指側の先端に取り付ける。
足台踵側（７）の後端は車椅子本体のフレームに足台先端（９）が変心カムの回転作用により上下運動する起点となるように連結する。
該車椅子の利用者の足は足台に設けられた固定帯（１０）で固定し、該電動モーターを駆動すると足台踵はフレームに連結されているため、変心カムの回転作用により足台先端（９）のみが上下し、車椅子の利用者の足も連動する。
この一連の作用により利用者のふくらはぎ（１１）は伸縮し、該ふくらはぎ内血管は圧縮と減圧をくり返すポンプ作用により血流の促進が計れ、この効能により血栓の予防も計れる。The wheelchair body (1) is provided with an electric motor (2), a battery (5) serving as a power source for the electric motor, and a battery charger (6) for the battery, and a solid base (12) for installing the wheelchair body on the wheelchair body. The eccentric cam (4) is provided at both ends of the rotating shaft of the electric motor, and one of the other ends of the eccentric cam is attached to the tip on the toe finger side.
The rear end of the footrest side (7) is connected to the frame of the wheelchair body so that the footrest tip (9) becomes a starting point for vertical movement by the rotating action of the eccentric cam.
The foot of the wheelchair user is fixed with a fixing band (10) provided on the footrest, and when the electric motor is driven, the footrest is connected to the frame. Only (9) moves up and down, and the foot of the wheelchair user is also linked.
By this series of actions, the user's calf (11) expands and contracts, and the blood vessel in the calf promotes blood flow by a pump action that repeatedly compresses and decompresses, and this effect also prevents thrombus.
本発明の車椅子は血流促進及び血栓予防機能付車椅子で、人為的に脚に外圧等を加えるものでなく、下半身が不自由で歩行等が困難な方でも、健常者が日常歩行する際と同様な脚機能が持つ血管のポンプ作用により血流の促進が自然と計れ、この効能により血栓の予防も計れるものである。
また、本発明の車椅子は屋内外で血流の促進が計れるが、屋外での使用が天候や気温等の影響により不適なときでも、血流促進機能が電動のため、電源の入、切、により、屋内停車時でも必要に応じ適宜停車位置で使用でき、利用者の健康が配慮できると共に介護人の労力の軽減も計れ、大変便利で効果的である。
さらに充電器（６）の利用により、ＡＣ１００Ｖの電気をバッテリー（５）へ充電して、利用できるので大変便利である。The wheelchair of the present invention is a wheelchair with a blood flow promotion and thrombus prevention function, and does not artificially apply external pressure to the leg, even when a normal person walks everyday even if the lower body is inconvenient and difficult to walk etc. Blood vessels can be naturally promoted by the blood vessel pumping action of the same leg function, and thrombus can be prevented by this effect.
In addition, the wheelchair of the present invention can promote blood flow indoors and outdoors, but even when outdoor use is unsuitable due to the influence of weather, temperature, etc., the blood flow promotion function is electric, so power on, off, Therefore, it can be used at an appropriate stop position as needed even when the vehicle is stopped indoors, and it is possible to consider the health of the user and to reduce the labor of the caregiver, which is very convenient and effective.
Furthermore, by using the charger (6), the battery (5) can be charged with AC 100V electricity, which is very convenient.
以下、本発明の実施の形態について説明する。
本発明は車椅子本体（１）に電動モーター（２）と該電動モーターの電源とするバッテリー（５）と充電器（６）を本体に設置する堅牢な台（１２）と変心カム（４）と足台と車椅子の利用者の足を固定する固定帯（１０）より構成される、
電動モーターの回転軸（３）の両端に変心カム（４）を軸設する。
変心カムの他端の一方は足台指側の先端に連結する。
足台踵側の後端は足台の先端が変心カムの回転作用により上下運動する起点となる様車椅子本体のフレームに連結する。
車椅子の利用者の足は、足台に設置された固定帯（１０）で固定する。
この機構により電動モーター（２）を駆動すると変心カム（４）の回転作用で足台の先端のみが上下すると共に利用者の足も足台と連動することから利用者のふくらはぎ（１１）は伸縮し、該ふくらはぎ内血管は圧縮と減圧をくり返すポンプ作用により脚の血流が促進される。
この効能により各種血栓の予防も計れる。
車椅子本体と該車椅子に設けた足台と該足台踵側の後端を車椅子本体のフレームに足台指側の先端が変心カムの回転作用により上下運動をする起点となるよう連結し、該電動モーターの回転軸の両端に変心カムを取り付け、他端一方は該足台指側の先端に連結する。
車椅子の利用者の足は該足台に設けられた固定帯で固定して電動モーターを駆動すると変心カムの回転作用で足台先端は上下運動を起す。
そのため、車椅子の利用者の足も連動上下するため、ふくらはぎ内血管は圧縮と減圧をくり返すポンプ作用により血流の促進が計れる。
この作用は各種血栓の予防につながる効能がある。Hereinafter, embodiments of the present invention will be described.
According to the present invention, an electric motor (2), a battery (5) as a power source of the electric motor, and a charger (6) are installed on the main body (1) of the wheelchair body (1). Consists of a footrest and a fixed band (10) that secures the foot of a wheelchair user,
Centering cams (4) are provided at both ends of the rotating shaft (3) of the electric motor.
One of the other ends of the eccentric cam is connected to the tip on the toe finger side.
The rear end of the footrest side is connected to the wheelchair body frame so that the tip of the footrest is the starting point for vertical movement by the rotating action of the eccentric cam.
The foot of the wheelchair user is fixed by a fixing band (10) installed on the footrest.
When the electric motor (2) is driven by this mechanism, only the tip of the footrest is moved up and down by the rotating action of the eccentric cam (4) and the user's foot is also interlocked with the footrest, so that the user's calf (11) can be expanded and contracted. In addition, the blood flow in the leg is promoted by a pump action that repeatedly compresses and decompresses the blood vessel in the calf.
This effect can prevent various blood clots.
The wheelchair body, the footrest provided on the wheelchair, and the rear end of the footrest side are connected to the frame of the wheelchair body so that the tip of the footrest is the starting point for vertical movement by the rotational action of the eccentric cam, Centering cams are attached to both ends of the rotating shaft of the electric motor, and the other end is connected to the tip on the footpad side.
When the foot of the wheelchair user is fixed by a fixing band provided on the footrest and the electric motor is driven, the tip of the footrest moves up and down by the rotating action of the eccentric cam.
Therefore, the foot of the wheelchair user also moves up and down, and the blood vessels in the calf can promote blood flow by a pump action that repeatedly compresses and decompresses.
This action has the effect of preventing various blood clots.
