Abstract:
A fluid filter assembly for filtering fluids such as blood is described. The assembly includes first and second filter housing elements formed by an injection molding process. Each element is flexible and includes a peripheral flange formed thereabout and a fluid communicating port formed therein. Filter media, such as a filter membrane, is sealed between the mating flanges of two elements. The fluid filter assembly is capable of collapsing and expanding during the filtration process depending upon the composition of the fluid passed there through. A method for making the filter assembly and systems for using the filter assembly are also disclosed.
Abstract:
A blood collection system has a container for holding blood and a filter communicating with the container, mutually arranged for handling as a unit. The filter (20) contains a fibrous filter medium (28) housed within two flexible sheets (32, 34) of plastic. A first seal (36) joins the sheets (32, 34) directly to the filter medium (28) inboard of the peripheral edge (40) of the filter medium (28), and a second seal (38) joins the sheets (32, 34) outboard of the peripheral edge (40) of the filter medium (28). A region (42) of the filter medium (28) extends between the first and second seals (36, 38) to cushion contact with the filter housing during handling.
Abstract:
A connector assembly is provided having a male component (12) and a female component (10) to provide fluid communication between a fluid source and a destination such as a patient. The female component (10) includes a door (28) rotatable about a hinge (30). The door (28) is forced open by a longitudinal member (34) within the male component (12). The door (28) is converted into a position parallel to the length of the female component (10) providing fluid communication between a tubing (36) extending into the female component (10). A sleeve (44) is further provided to permit and to prevent fluid flow through a tubing by rotation of the sleeve (44) resulting in compression and expansion of longitudinal members (46) within the sleeve (44) and thereby the tubing.
Abstract:
A method for creating a plastic component con- structed, at least in part, from polychlorotrifluoroethy- lene, having improved properties, comprising the steps of: creating a compound from a composition that com- prises polychlorotrifluoroethylene; heating the compo- nent to a temperature that is greater than the melting point of the composition; and rapidly quenching the component in a cold medium.
Abstract:
Una máquina de suministro de fluido, tal como una máquina de diálisis o hemodiálisis peritoneal, incluye un surtidor o casete (3) que bombea un fluido médico para diálisis u otros tratamientos para pacientes. La maquina incluye y utiliza un dispositivo de auto-conexión (5) para conectar recipientes de liquido, tales como bolsas de fluido de diálisis o fluidos de medicamento, a la maquina, mientras se mantiene la esterilidad de la conexión. El dispositivo de auto-conexión remueve la tapa de la tubería de la bolsa de fluido y perfora la membrana de sellado en la tubería. Eso facilita más que los pacientes reciban el tratamiento, especialmente en tratamiento casero. Otras modalidades son útiles para el suministro de otros líquidos a partir de otros tipos de máquinas de suministro o de bombeo.

Abstract:
A connector assembly and disinfectant system is provided for any system requiring a connection, such as during a peritoneal dialysis procedure. The connector assembly includes a transfer set connector and a disposable connector. The transfer set connector and disposable connector each include a member that join to create a fluid path. The disposable connector contains a housing that includes a ring partially saturated with disinfectant for bathing the transfer set member near the opening of the fluid path when a connection is made. The ring forms an opening through which the transfer set member passes. At disconnection, the transfer set member passes through a section of the ring having wiping properties to wipe the member dry.
