摘要： Medical intravenous administration connectors include a first coupling member having a female luer, a valve member having a substantially rigid stem and a substantially resilient body with a sealing surface, and a second coupling member having a fluid coupling extending from one end and an internal valve member support. The coupling members are structured to couple to each other with the valve member being biased to a closed position. When assembled, the valve stem extends into the female luer, and the valve body biases the sealing surface against an annular ring in the first coupling member thereby blocking fluid communication. Preferably, vanes are provided in the second coupling member on which the resilient body of the valve sits, with the vanes acting as a centering mechanism for the valve. The valve may be opened for fluid flow through the assembly by coupling a male luer to the female luer of the assembly, or by pressure actuation. Several valve members are disclosed and several structures for mating the first and second coupling members are disclosed. Y-injection sites and intravenous manifolds utilizing the valve arrangement and coupling members of the invention are also disclosed. All embodiments are easy to prime, limit priming volume, and are arranged without dead-spaces in which blood can be trapped.

摘要： A device for cleaning and disinfecting needle-free intravenous connectors includes a cap, a sponge-like absorbent material impregnated with a disinfectant agent, and a hermetic seal. The cap defines a cavity whose walls are lined with the absorbent material and is sized to receive a needle-free intravenous connector. A hermetic seal provided for the cap seals the cavity and preserves the disinfectant agent contained in the absorbent material. The device is used by removing the hermetic seal, placing the cavity of the cap over the septum and thread profile of the connector, pushing the cap down on the septum portion of the IV connector so that the outer threads and septum of the connector slidingly interfere with the absorbent material containing the disinfectant agent, and twisting the cap back and forth to clean and disinfect the septum and thread profile. The device is discarded after use.

摘要： Medical intravenous administration connectors according to a first embodiment include a first coupling member having a female luer, a valve member having a substantially rigid stem and a substantially resilient body with a sealing surface, and a second coupling member having a fluid coupling extending from one end and an internal valve member support. The coupling members are structured to couple to each other with the valve member being biased to a closed position. When assembled, the valve stem extends into the female luer, and the valve body biases the sealing surface against an annular ring in the first coupling member thereby blocking fluid communication. Vanes are provided in the second coupling member on which the resilient body of the valve sits, with the vanes acting as a centering mechanism for the valve. The valve is opened for fluid flow through the assembly by coupling a male luer to the female luer of the assembly. According to a second embodiment, the valve stem is replaced by a dome-like protrusion on the resilient valve body. The valve of the second embodiment is opened by applying fluid under pressure through the female luer. According to a third embodiment, the valve is partially rigid and partially resilient. All embodiments are easy to prime, limit priming volume, and are arranged without dead-spaces in which blood can be trapped.

摘要： A drug vial adapter according to the invention includes: a first coupling member having a female luer connector (preferably a luer lock) with a fluid path therethrough, a flange having a first sealing ring seat formed therein and a first mating structure; a second cylindrical coupling member having a centrally located septum piercing tube with a fluid path therethrough and a second mating structure; and a valve member including a valve stem and a resilient valve body having an annular sealing surface. A valve body seat is formed in the interior of the second coupling member by a plurality of radially arranged stepped vanes. According to a preferred embodiment, the second coupling member is formed as a stepped cylinder having a relatively large diameter adjacent the point of the septum piercing tube, a relatively small diameter adjacent the valve body seat and an intermediate diameter therebetween. The presently preferred valve body is substantially frustroconical having a relatively broad end with a stepped axial bore defining the annular sealing surface. The presently preferred valve stem has a stepped cylindrical portion which fits into the axial bore of the valve body and a pair of spaced apart upstanding members which extend into the female luer.

摘要： A surgical trocar assembly includes a disposable valve assembly, a cannula assembly, and a trocar with a handle. The cannula assembly includes a cannula base having a valve assembly coupling device at its proximal end, and a cannula extending from its distal end. The disposable valve assembly has a coupling device for removably coupling it with the cannula base. The valve assembly also includes a valve body with a fluid passage communicating with the hollow cannula when it is coupled to the cannula base. A slit or flapper valve and a universal washer are mounted within the valve body and allow the insertion of the trocar or other endoscopic instruments therethrough while providing a fluid sealing of the fluid passage. The valve assembly may be provided with a side port which optionally contains an automatic valve actuated by a luer coupling. Several different valve assembly-cannula base couplings are disclosed as well as several different types of trocars.

摘要： An automatic fluid valve which permits insertion of a surgical instrument therethrough is disclosed and includes an elastomeric slit valve with a plurality of raised surgical instrument engaging protrusions on a proximal surface thereof. Typically, the slit valve is a tricuspid valve, and three protrusions would be provided. The protrusions may take many forms, including barbells or other shaped elements which are insert molded into the slit valve, or bumps which are molded as part of the slit valve. If the protrusions are insert molded, the protrusions are preferably made of a material having a coefficient of friction lower than then the coefficient of friction of the elastomeric, typically silicone, member. If the protrusions are part of the valve, they are preferably coated with a slippery coating such as TEFLON. The faces of the protrusions may also take different forms such as hemispheres, or elongated ribs.
