  • Publication number: 20090028750
    Abstract: 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.

  • Patent number: 6299131
    Abstract: A needleless IV injection port assembly includes a spiked body provided with a hollow spike, a female luer component, a flexible and resilient spike boot having a tip and spring portion, a centering member, and a resilient swabbable septum. The spike boot extends over the spike, the centering member is provided over a portion of the spike and spike boot, and the septum is provided between the centering member and an end of the female luer component. The spiked body and the female luer component are secured together to complete the assembly. The length of the female luer component and/or the length of the spike is chosen so that when a separate male luer is positioned over a protuberance on the septum and pushed into the female luer component, the male luer places pressure upon the septum which thereby urges the septum toward the spike. The pressure on the septum causes the spring portion of the boot to be compressed and the tip portion of the boot to be pierced by the tip of the spike.

  • Patent number: 6158458
    Abstract: 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.

  • Patent number: 6113068
    Abstract: A needleless IV injection port assembly includes a spiked body provided with a hollow spike, a female luer component, a flexible and resilient spike boot having a tip and spring portion, a centering member, and a-resilient swabbable septum. The spike boot extends over the spike, the centering member is provided over a portion of the spike and spike boot, and the septum is provided between the centering member and an end of the female luer component. The spiked body and the female luer component are secured together to complete the assembly.

  • Patent number: 6099505
    Abstract: 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.

  • Patent number: 5833213
    Abstract: 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.

  • Patent number: 5312363
    Abstract: 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.
