Fill cap for a drink container

Combined collection and cover structure for a receptacle

A vent and fluid transfer fitment for sealing and transferring a fluid from an inverted fluid-filled container without premature leakage to a receiver attachment, has a transfer check valve and a venting check valve which are preferably duckbill valves. The transfer check valve is attached to the fitment for allowing fluid to be transferred from the container when the receiver attachment engages the transfer check valve. The venting check valve is also attached to the fitment for allowing air to displace the fluid as the fluid exits the container, wherein both the transfer check valve and the venting check valve have an inherent sealing pressure created by the static pressure of the fluid within the container. In addition, the inherent sealing pressure of the venting check valve is less than the inherent sealing pressure of the transfer check valve which allows air to enter the container due to the pressure differential created as the fluid is displaced.

Integrated vent and fluid transfer fitment

A hemostasis valve assembly adapted for use within a catheter introducer is disclosed. The valve assembly includes first, second and third sealing members wherein the second sealing member comprises a guide wire seal. The guide wire seal includes a plurality of lip members defining two pairs of diametrically opposed slits and an aperture intersecting at least one of the slits. The aperture is adapted to sealing engage a small diameter guide wire for preventing fluid flow out of the catheter introducer through the valve assembly, while the slits allow for the passage of a large diameter elongated member or catheter. Two pairs of diametrically opposed pre-load ribs extend radially towards the aperture for pressing the lip members together in sealing engagement. A substantially spherical inner surface is provided for guiding the guide wire to the aperture.

Hemostasis valve assembly including guide wire seal

A check valve including a housing formed by a base portion and a cap portion positioned in telescoping relation with each other. A disc shaped valve member is positioned within the housing and is defined by opposing first and second planar sides. The valve member includes a spherical portion located centrally thereon and which is captured between first and second valve supports supported on the base portion and cap portion, respectively. The valve supports hold the valve member in engagement with a valve seat, and the valve member moves out of engagement with the valve seat in response to a fluid pressure applied at a fluid inlet in the base portion to permit forward fluid flow while preventing fluid flow in the reverse direction.

Disc type check valve

A dual valve assembly for use with a dispensing apparatus including a pump and a plurality of fluid containers. The valve assembly includes a housing containing an elastomeric regulator wherein the regulator includes a diaphragm portion for controlling fluid flow through the housing, and a vent valve structure for opening and closing air passages to supply air to the containers. The diaphragm portion includes an orifice, and the diaphragm portion is movable into and out of contact with a seat defined on the housing to control fluid flow from the containers and through the orifice during actuation of the pump. In addition, the vent valve structure includes a pair of vent membranes which open vent openings to the containers in response to negative pressure applied from the pump.

Dual dispensing valve assembly

The present invention provides a medical coupling site which is adapted to be attached directly to a standard male luer lock fitting. The coupling site includes a valve element contained within a tubular housing. The housing is provided with a threaded portion for engaging the threaded locking collar of a male luer lock whereby the male luer lock will be held in positive mechanical locking engagement with the coupling site. The valve element is provided with rib members extending inwardly from an inner wall of the valve element toward a slit formed in a diaphragm such that the rib members act to bias the slit to a closed position. The housing includes a flange extending radially inwardly over the diaphragm and defining a diameter for frictionally engaging a male luer in locking engagement. In addition, an exposed surface of the diaphragm is formed with surface texturing to define a roughened surface. The roughened surface reduces the surface friction between the diaphragm and a male luer as the luer is inserted through the diaphragm.

Medical coupling site valve body

The present invention provides a medical coupling site which is adapted to be attached directly to a standard male luer lock fitting. The coupling site includes a valve element contained within a tubular retainer. The valve element is formed of a resilient material having greater than that of the retainer, and has a diaphragm including a concave surface with a slit extending diametrically across the surface. The valve element is provided also with biasing means extending inwardly from an inner wall of the valve element into a passage in the valve element such that the biasing means act to bias the slit to a closed position. In a preferred form, the retainer has an outer wall with a maximum outer diameter of approximately 7 mm and an inner wall of the valve element has a minimum inner diameter of approximately 4 mm.

A method and apparatus for simultaneously sterilizing and lubricating a medical coupling site prior to insertion of a male luer into the site. A fiber pad is provided containing a liquid composition including a sterilizing agent and a lubricating agent. The sterilizing and lubricating agents are preferably isopropyl alcohol and silicone oil, respectively, such that application of the lubricating agent to the medical coupling site results in the alcohol evaporating to leave behind a coating of silicone oil. The silicone oil lubricates an area on the coupling site contacted by the end of a male luer.

Method of lubricating a medical coupling site

The present invention provides a medical coupling site which is adapted to be attached directly to a standard male luer lock fitting. The coupling site includes a valve element contained within a tubular retainer. The retainer is provided with outwardly extending lugs for engaging the threaded locking collar of a male luer lock whereby the male luer lock will be held in positive mechanical locking engagement with the coupling site. The valve element is provided with rib members extending inwardly from an inner wall of the valve element toward a slit formed in a diaphragm such that the rib members act to bias the slit to a closed position. In addition, the valve element is formed with biasing means for engaging an inner wall of the retainer whereby the slit is further biased to a closed position.

The present invention provides a medical coupling site including an elastomeric valve element defined by a tubular body portion and a diaphragm extending diametrically across an end of the body portion. The diaphragm includes a slit having opposing slit ends which terminate in spaced relation to an inner wall of the body portion. First and second elastomeric stiffening ribs are formed integrally with the diaphragm and the body portion adjacent to the ends of the slit, and the stiffening ribs act to prevent the diaphragm from tearing adjacent to the slit ends and facilitate alignment of adjoining surfaces in the diaphragm defining the slit.
