摘要： A check valve for sealing a fluid supply while permitting selective withdrawal of fluid includes a tubular side wall (12) defining an insertion end (14) and a supply end (16). A diaphragm (18) is connected to the side wall and extends across the tube interior to close the interior. The diaphragm defines a slit (20) therein extending diametrically across the diaphragm. The diaphragm is defined as a concave surface toward the insertion end of the side wall. A housing (30, 32) secures the side wall, encloses the supply end thereof, and exposes the insertion end. A port (38) extends through the housing to communicate with the supply end.

摘要： A one-way duckbill check valve assembly for allowing fluid flow in a first direction and for preventing fluid flow in a second, opposite direction comprises a valve housing (10,12) having first and second ports opening into the housing, and a flow regulator (14) positioned within the housing and including an outer wall (52) which is formed as a substantially cylindrical member. The regulator includes a pair of semi-circular valve lips (38,40) which are oriented in converging relationship to each other to form an outlet slit (28) at one end of the regulator. These valve lips are connected to the outer wall (52) by a pair of concave connecting walls (42,44) and the lips and connecting walls form a pair of cavities on either side of the outlet slit (28). A pair of elongated projections (68,70) are located along diametrically opposing sides of the outer wall (52) for biasing the outer wall inwardly whereby a biasing force is applied to close the lips (38,40).
摘要翻译：用于允许流体沿第一方向流动并且用于防止在第二相反方向上的流体流动的单向鸭嘴止回阀组件包括具有通向壳体的第一和第二端口的阀壳体（10,12），以及流量调节器（14），其定位在所述壳体内并且包括形成为大致圆柱形构件的外壁（52）。调节器包括一对半圆形阀嘴（38,40），它们彼此会聚，并在调节器的一端形成出口狭缝（28）。这些阀瓣通过一对凹连接壁（42,44）连接到外壁（52），并且唇缘和连接壁在出口狭缝（28）的任一侧上形成一对空腔。一对细长突起（68,70）沿着外壁（52）的沿径向相对的侧面设置，用于向内偏压外壁，由此施加偏压力以闭合唇缘（38,40）。

摘要： A medical coupling site (210) adapted to be directly coupled to a standard male luer includes a rigid housing (214) containing an elastomeric valve element (216) comprising a tubular body having a wall thickness which progressively increases in a direction away from an integral diaphragm (234) which closes the upper end of the body. The housing (214) includes an annular flange (229) having a locking edge (231) which frictionally engages the male luer when inserted through a slit (236) in the diaphragm, to lock the luer in position. A pair of reinforcing ribs (244, 246) are formed integrally with the diaphragm and extend radially inwardly toward each other from the tubular body wall to bias the slit closed. The ribs are reduced in thickness intermediate their ends to form hinge points to facilitate flexing of the diaphragm when the luer is inserted.

摘要： A valve assembly for permitting flow in a first direction and for preventing flow in a second, opposite direction includes a resilient flow regulator (14) having a pair of lips (16) arranged in a converging relationship to define a normally closed slit (22) at the outer ends (20) of the lips. A housing outlet portion (10) defines a housing interior approximating the shape of the regulator (14), having a pair of planar surfaces (28) corresponding to the pair of lips. The housing outlet portion (10) further includes an annular collar (36) disposed outwardly adjacent the base of each planar surface. The regulator is disposed within the housing outlet portion with an annular flange (26) thereof contained within the collar (36) and with the lips (16) being adjacent to, but not in contact with, the planar surfaces. A cover plate (40) is attached to the collar for securing the regulator and for sealing the housing. Each of the planar surfaces (28) of the housing interior includes a raised portion (48) formed thereon adjacent its base and extending along at least a portion thereof. The raised portions (48) are each formed of a height sufficient to cause the raised portion to contact the lip surface adjacent thereto.
