摘要： An intravascular valve component broadly includes a valve case and a flexible pressure-actuated flow control valve. The valve case includes attached proximal and distal case portions that present respective spaced apart fluid ports and a fluid passageway extending between the ports. The flexible pressure-actuated flow control valve is disposed within the fluid passageway and includes a slitted central valve wall and an annular flange surrounding the central valve wall. The annular flange includes a radially-extending flange wall and a projection extending axially from the flange wall, with the projection engaging one of the case portions to restrict radial movement of the flow control valve relative to the valve case.

摘要： An improved injection site (12) for infusion of parenteral fluids and the like is provided, having a pressure-actuated valve (20) and a novel split septum unit (24), which effectively prevent reflux of blood into the assembly (10). The septum unit (24) includes a resilient split septum body (64) which is precompressed so that the septum body (64) is caused to protrude proximally (78) upon insertion of a cannula (16). Consequently, upon removal of the cannula (16), there is essentially no "drumming" or creation of friction-induced negative pressures sufficient to generate blood reflux. The preloaded septum body (64) also has its proximal surface (74) essentially flush and coplanar with the adjacent proximal end (66b) of the tubular septum holder (66) to enhance the cleanliness of the unit (24). The specialized well (46) and septum unit (24) afford a resilient seal between the periphery of the septum body (64) and the surface (50), and a separate hard-surface seal between the outer margin of the surface (50) and the septum holder (66).
