摘要：
PROBLEM TO BE SOLVED: To provide an injection device for medical fluid using medical fluid transfer and/or such a valve.SOLUTION: A fluid flow control valve comprises: a valve body 70 comprising a fluid flow lumen passing through the valve body； and a valve member 72 positioned in the fluid flow lumen. At least one of the valve body and the valve member has elasticity, and the valve body and the valve member are formed into a size for allowing motion between a normal closed position in which the valve member and a surface of the fluid lumen are sufficiently contacted in an annular contact for blocking the fluid flow passing through the fluid flow lumen, and an open position where at least one of the valve body and the valve member is bent to a separation position where the fluid flow between them is allowed. A downstream fluid pressure contacts the valve body for enhancing seal. The fluid absorbent member is also arranged with the valve body. The valve may be used for a flow control device such as a medical fluid injection device and a method therefor.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】医療用流体移送および／またはそのような弁を用いる医療用流体の注射装置を提供する。【解決手段】流体流制御弁は、弁体を通る流体流内腔を有する弁体７０と、流体流内腔内に位置する弁部材７２とを含む。弁体と弁部材との少なくとも１つは弾性であり、それぞれ、流体流内腔を通る流体流を遮断するために弁部材と流体内腔表面とが十分に環状接触の状態にある通常の閉鎖位置と、弁体と弁部材の少なくとも１つがそれらの間の流体流を許容する離間位置に向かって屈曲する開放位置との間の動きのための大きさにされている。下流の流体圧は封止を強化するために弁体に接触する。流体吸収部材もまた弁体とともに備えられ得る。医療用流体注射装置のような流れ制御装置と方法はこの弁を用い得る。【選択図】図４
