  • Patent number: 7790103
    Abstract: A medical fluid machine, such as a dialysis machine, includes a pump that pumps a medical fluid and sterile water or other disinfecting liquid, such as ozonated water, for flushing and reconditioning the medical fluid machine. The machine may also include a heater that heats the medical fluid or disinfecting solution in order to kill bacteria and other microorganisms that may contaminate the machine after use. Disinfecting the machine, and a disposable kit used with the machine, may allow re-use of the disposable within a reasonable amount of time after completion of the disinfecting procedure. Dialysate treated with ultra-violet light or water with low concentrations of ozone also helps make the disposable kits suitable for reuse.

  • Publication number: 20090294339
    Abstract: A peritoneal dialysis machine includes an enclosure; dialysate pump located within the enclosure; a graphical user interface connected to the enclosure and configured to display a parameter associated with the dialysate pump; and a projector configured to project the parameter onto a surface external from the enclosure so as to allow a patient to readily view the parameter.

  • Publication number: 20090054873
    Abstract: A laser strikes and aseptically heats or sterilizes the end of two flexible tube ends for connection. Tube holders are pushed toward each other to bring the tube ends into contact. A weld detector checks the characteristics of the weld. A laser optics assembly may be used to chance the direction of the lacer and focus the laser at the tube ends. In addition, a crimping device is used to compress a single flexible tube for disconnection. The laser strikes the compressed area. The crimping device continues to pinch the area and forms a seal in the tube. The tube is separated into two tube segments, each segment has a sealed end.

  • Publication number: 20090012449
    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.

  • Patent number: 7459054
    Abstract: A laser strikes and aseptically heats or sterilizes the end of two flexible tube ends for connection. Tube holders are pushed toward each other to bring the tube ends into contact. A weld detector checks the characteristics of the weld. A laser optics assembly may be used to change the direction of the laser and focus the laser at the tube ends. In addition, a crimping device is used to compress a single flexible tube for disconnection. The laser strikes the compressed area. The crimping device continues to pinch the area and forms a seal in the tube. The tube is separated into two tube segments, each segment has a sealed end.

  • Patent number: 5496357
    Abstract: A thermal blanket with an elastic fit to accommodate body movement and particularly suitable for compressive post-operative thermal treatment of body joints such as the shoulder, ankle, knee, elbow, hand/wrist, back or hip, is disclosed. The blanket includes a bodyside first panel composed of double layers of thermoplastic sheet material heat-sealed together to define at least one and preferably two serpentine fluid flow passages for the circulation of cooling (or warming) fluid. The sheet material may alternatively define a relatively open passageway between an inlet and outlet. The blanket also includes a soft, foldable exterior second panel coplanar with the first panel, the edges of the two panels being secured together to form a unitary, easily-foldable blanket. The exterior panel is of soft loop-providing pile fabric over substantially the entire exterior surface thereof.
