摘要： A septum (1) is held in the cavity of a cover (6) and mounted on a pedestal (7) forming part of a flow channel, and comprises a main body having a through passageway and compression ribs formed in the sides thereof. In the main body, the vertical diameter of the cross section orthogonal to the through passageway is longer than the transverse diameter, and the through passageway includes a vertical diameter direction slit (4) formed in the vicinity of the outer end surface of the main body, and a hole (5) that is formed in a region extending from the slit to the inner end surface of the main body and whose cross section is spindle-shaped having a longer axis extending in the vertical diameter direction. The compression ribs are formed in the opposite sides of the main body in the transverse diameter direction, and the cavity of the cover is of circular cross section whose diameter is shorter than the outer surface spacing between the compression ribs. With the septum mounted, a space is defined between part of the surface of the main body and the inner wall surface of the cover. Further, the hole is closed by a compressive force acting on the septum from the inner wall surface of the cover through the compression ribs. The through passageway in the septum hardly forms a dead space that would cause a residual liquid therein, and the slit in the septum surface hardly opens even at the time of pressurization.

摘要： A medical instrument includes a housing with a passage through which a catheter is received. A valve body is mounted in the passage, and, as the catheter penetrates through the valve body, the valve body conforms to the outer wall of the catheter to maintain a fluid tight seal between the valve body and the catheter. When the valve body is unstressed before being mounted in the passage, the valve body has a first planar dimension and a second planar dimension that is less than the first planar dimension.

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。

摘要： A trocar having a working channel extending along an between a distal end and a proximal end includes a cannula at the distal end and a housing at the proximal end which define a working channel of the trocar. A valve disposed in the working channel separates the trocar into regions proximal of the valve and regions distal of the valve. The valve includes elastomeric means which form a first seal that is openably closable across the working channel. A wall of the valve extends radially outwardly of the elastomeric means and forms a second seal with the housing. The trocar also includes means for defining a passage extending from regions exterior of the trocar through the regions proximal of the valve and into the regions distal of the valve. Valve means disposed across this passage controls the administration of fluid through the passage and into the working channel of the cannula.

摘要： A valve mechanism for a needleless connector employs a deformable piston having a piston head of elliptical cross-section with a marquise-shaped bore formed along its longitudinal axis wherein the major axes of the respective generally elliptical shapes are oriented perpendicular to one another. The piston head is captured within the connector housing and is reciprocal between a section of reduced diameter adjacent the connection port and a section of enlarged diameter. Constraining the piston head into the section of reduced diameter causes the elliptical bore to be squeezed shut while positioning the piston head in the section of enlarged diameter causes the piston head to relax and assume its natural elliptical shape, while the bore similarly regains its natural open shape to provide a fluid path therethrough. A compressible or extendible section affixed to the piston head serves to bias the piston into the section of reduced diameter. A tapered section of the piston contacts the housing to secure the top of the piston flush with the top of the housing for ease in cleaning.
摘要翻译：用于无针连接器的阀机构使用具有椭圆形截面的活塞头的可变形活塞，其具有沿着其纵向轴线形成的侯爵形孔，其中各个大致椭圆形的长轴彼此垂直定向。活塞头被捕获在连接器壳体内并且在相邻于连接端口的直径减小的部分和具有增大直径的部分之间往复运动。将活塞头限制在直径减小的部分，导致椭圆形孔被关闭，同时将活塞头定位在直径增大的部分中，使活塞头松弛并呈现其天然椭圆形状，而孔同样恢复其自然开放形状以提供穿过其中的流体路径。固定在活塞头上的可压缩或可延伸的部分用于将活塞偏压成直径减小的部分。活塞的锥形部分接触壳体以固定活塞的顶部与壳体的顶部齐平，以便于清洁。
