  • Disposable medical fluid unit having rigid frame
    Patent number: 7175606
    Abstract: A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a frame of a disposable unit for a medical fluid system is provided. The frame includes a body having a pair of opposing sides and defining a space between the sides, and a number of membranes sealed to the body along the opposing sides. The body and the membranes form at least one medical fluid pathway in the space between the opposing sides, and the opposing sides are bowed.
    Type: Grant
    Filed: May 24, 2002
    Date of Patent: February 13, 2007
    Assignees: Baxter International Inc., Baxter Healthcare S.A.

  • Medical system including vented tip protector
    Patent number: 7083719
    Abstract: A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a medical system is provided that includes (i) a liquid pump; (ii) tubing in communication with the liquid pump; and (iii) at least one processor that operates with the liquid pump to: (a) pump liquid through the tubing, the tubing having an end and a hydrophobic filter at the end, the filter allowing air but not the liquid to escape from the end of the tubing, (b) receive a signal indicating a pressure increase inside the tubing, and (c) cause the pumping to stop when air has been purged substantially from the tubing.

  • Vented medical fluid tip protector methods
    Patent number: 6929751
    Abstract: A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a member for removably securing a medical fluid tube is provided. The member includes a body providing a first fluid pathway and an opening for removably receiving an end of the medical tube. The first fluid pathway is placed in fluid communication with a second fluid pathway defined by the tube when the end of the tube is removably receiving. The member further includes a filter so positioned and arranged so as to cause fluid flowing through the first fluid pathway to pass through the filter, the filter allowing air but not liquid to flow through the first fluid pathway.
