  • Patent number: 9586003
    Abstract: A system for automatically connecting tubing to a medical fluid machine includes at least one fluid container including a tube having a cap on an end of the tube, a shuttle configured to receive the tube, a driving mechanism configured to translate the shuttle, a cap removal device configured to remove the cap from the end of the tube, and a control unit programmed to cause (i) the driving mechanism to translate the shuttle holding the tube in a first direction towards the cap removal device so that the cap removal device can engage the tube cap, (ii) the driving mechanism to translate in a second direction away from the cap removal device so that the cap removal device removes the cap from the end of the tube, and (iii) the driving mechanism to translate the shuttle in the first direction with the cap removed from the tube so that the tube can be mated with the medical fluid machine.

  • Patent number: 7955295
    Abstract: A fluid dispensing machine, such as a peritoneal dialysis or hemodialysis machine, includes a dispenser or cassette that pumps a medical fluid for dialysis or other treatments for patients. The machine includes and uses an autoconnect device for connecting containers of liquid, such as bags of dialysis fluid or medication fluids, to the machine, while maintaining the sterility of the connection. The autoconnect device removes the cap from the fluid bag and pierces the scaling membrane on tubing from the bag. This makes it easier for patients to receive treatment, especially home treatment. Other embodiments are useful for dispensing other liquids from other types of dispensing or pumping machines.

  • Publication number: 20030209479
    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.

  • Patent number: 6601710
    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.

  • Patent number: 5743892
    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.

  • Patent number: 5637267
    Abstract: A method is provided for creating a plastic component constructed, at least in part, from polychlorotrifluoroethylene, having improved properties. The method creates a component from a composition that has polychlorotrifluoroethylene, heats the component to a temperature that is greater than the melting point of the composition, and rapidly quenches the component in a cold medium.

  • Patent number: 5533996
    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.
