Abstract:
A unitary, sterile fluid dispensing assembly and a method of forming the assembly (10) includes forming a fluid-filled container (12) with a vinyl dispensing port (14) and forming a fluid transfer set (17) with a vinyl spike connector (40). The spike connector (40) is inserted into the vinyl dispensing port (14) thereby placing the set in fluid flow communication with the fluid (F) in the container (12). The assembly (10) is sterilized in an autoclave. The heat of sterilization melds at least a surface portion of the vinyl spike connector (40) and softens an interior adjacent surface portion of the port (14) on the container (12). After sterilization, the transfer set (17) is permanently bonded to the container (12). The presence of the fluid (F) in the transfer set during sterilization prevents fusing and closing of the lumens of the set due to the heat of sterilization.
Abstract:
A method of radio frequency sealing attaches a seal member (30) to a cylindrical, hollow, access port (20) of a container. The method uses two sets of spaced apart die elements (12a, b and 14a, b) to generate an axial electric field along a region where the port and seal member overlap. An external peripheral ring (42) is formed about an exterior surface of the port. The method can be used with containers having a sealed periphery as well as those previously filled with a fluid.
Abstract:
A port and closure assembly for a container is provided. The port and closure assembly includes a port having a tubular portion that extends from a base and terminates at an end including an opening. The tubular portion is divided into an upper and lower section by a pierceable membrane. The upper section including an end that terminates at the opening and including a resealing injection site. A closure member for removably surrounding at least a portion of the end of the port including the opening is provided. The closure includes a sleeve that circumscribes at least a portion of an outer surface of the upper section of the tubular portion. The sleeve is so constructed and arranged as to cause portions of the upper section to contact the resealing member during a sterilization step that softens the portions and further causes the portions of the upper section to retain the resealing injection site within the tubular portion after the portions have hardened.

Abstract:
DETACHABLE PERITONEAL DIALYSIS SET A peritoneal dialysis connection set comprises flexible tubing (12) including a central portion of the tubing having a free end. First connector means (14) are carried on the free end and adapted for removable, sealed, flow-through connection with tubing communicating with the peritoneal cavity of the patient. At least two lengths of branch tubing (28, 30) communicate with the central tubing portion, each of the lengths of branch tubing defining a free end and respectively carrying second and third connector means (32, 34) at the free ends. The second and third connector means are each adapted for removable, sealed, flow-through connection with a connector communicating with a dialysis solution container, and the first connector (14) is also adapted for removable, sealed connection with either of the second and third connectors (32, 34) in a storage mode of the set. The set can be reused for providing and removing peritoneal dialysis solution from the peritoneal cavity of a patient, and then may be returned to its storage mode and stored separate from the patient during the "dwell" period of peritoneal dialysis therapy.
Abstract:
UNIVERSAL CONNECTOR A universal connector for a fluid flow conduit 14 comprises a tubular connector 12 for attachment at one end to the fluid flow conduit and defining a luer taper tube portion 16 at its other end. A sleeve 18 is carried by and surrounding the tubular connector 12 in relatively rotatable relation thereto. the sleeve 18 defines internal threads 20 for threaded locking connection with another connector. A tubular member 22 having external threads 24 at one end is locked by said external thread in removable threaded locking connection with the internal threads 20. The tubular member defines at its other end an aperture 26 for sealingly receiving a spike connector.
