Abstract: Apparatus for the automated transfer of contents between a rubber diaphragm port-type vial and a flexible, collapsible bag for medical solutions, which bag has at least one needle-pierceable access port. A double-pointed hollow needle is positioned so that the vial is held with its rubber diaphragm facing one pointed end of the needle and the medical solution bag is held with its needle-pierceable access port facing the other pointed end of the needle. Apparatus is provided for bringing the vial and bag into needle-penetrated relation, to provide flow communication therebetween through the hollow needle. Means are also provided for compressing the bag to force liquid from the bag into the vial, and for releasing the compression to allow the liquid to flow from the vial back to the bag. As a result of this, the original contents of the vial may be carried into the bag in automated manner.

Abstract: A container which includes body, neck and cover portions of one-piece plastic construction and a line of weakness defined between the neck and cover portions to permit selective separation of the cover from the neck, further includes an inner closure carried by and removable with the cover portion to prevent spillage of the container contents upon opening of the container. The inner closure is disposed to seal the neck below the line of weakness to isolate the contents of the container from the area of the line of weakness. When the container is heat sterilized, means is provided associated with the chamber defined by the cover and closure to prevent collapse of the cover during the post heat-sterilization cooling cycle. The associated means includes structure to provide moist air in the defined chamber during heating of the container without endangering the sterility of the container contents or nullifying the advantage of the inner closure.

Abstract: Improved valves for use within medical devices include a valve body having a plurality of fluid-passing openings, a resilient liner having raised portions defining flow paths, and a plug having a configuration generally complementary to that of the liner, at least a portion of the plug generally overlying the liner for maintaining raised portions of the liner in sealing engagement with the valve body in a manner that enhances valve integrity as to leakage while simultaneously improving valve operation by providing easy rotation of the plug and liner with respect to the valve body. The in-use illustrated embodiment of the valve is on a urine drainage device, the valve being interposed between a relatively rigid urine flow monitoring and measuring chamber and a flexible collection receptacle, the valve permitting flow path selections for retaining urine within the measuring chamber or for flowing urine therefrom into the flexible collection receptacle or through a sampling port.
