摘要： A closed system, spikeless, positive-flow valve device includes a body defining an internal cavity. At the proximal end of the body is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The valve includes a plastic, resilient silicon seal which fills the upper cavity and opening with an oval seal cap having a slit. The opening presses the oval seal cap to keep the slit closed in the decompressed state. The slit opens as the nose of the medical implement compresses the seal into the cavity and the seal cap is free from the opening. The housing also includes a fluid space which facilitates fluid flow between the medical implement and a catheter tip. The fluid space within the valve automatically and reversibly increases upon insertion of the medical implement into the cavity and decreases upon withdrawal of the medical implement, such that a positive flow from the valve toward the catheter tip is effected upon withdrawal of the medical implement, thereby preventing a flow of blood from a patient into the catheter when the medical implement is removed from the valve.
摘要翻译：封闭系统，无尖锐的正流阀装置包括限定内腔的主体。在身体的近端处是优选地足够大以接收医疗器具的ANSI标准尖端的开口。该阀包括塑料弹性硅密封件，其填充上腔体并用具有狭缝的椭圆形密封盖开口。开口按压椭圆形密封帽，使狭缝在解压缩状态下闭合。当医疗器具的鼻子将密封件压入空腔并且密封帽没有开口时，缝隙打开。壳体还包括便于流体在医疗器具和导管尖端之间流动的流体空间。当医疗器具插入空腔中时，阀门内的流体空间自动地和可逆地增加，并且在医疗器具撤回时减小，使得从医疗器具撤回时从阀门朝向导管尖端的正向流动被实现，从而当医疗器具从阀门移除时，防止血液从患者流入导管。
