Patents Assigned to Outset Medical, Inc.
  • Patent number: 11951241
    Abstract: Described herein are systems and methods for performing peritoneal dialysis. According to one aspect, the disclosure provides a sterile interface connection for connecting a water purification system to a disposable source of dialysate concentrates. The sterile interface connection can include a chamber comprising an inlet adapted to be connected to the water purification system on a proximal end and a valve on a distal end. The sterile interface connection can also include spring-loaded needle disposed in the chamber. The spring-loaded needle can move between a retracted configuration in which the spring-loaded needle is fully retracted into the chamber and the valve is closed and sealed, and an extended configuration in which the spring-loaded needle extends through the valve into the disposable source of dialysate concentrates.

  • Patent number: 11724013
    Abstract: Certain disclosed embodiments concern systems and methods of preparing dialysate for use in a home dialysis system that is compact and light-weight relative to existing systems and consumes relatively low amounts of energy. The method includes coupling a household water stream to a dialysis system; filtering the water stream; heating the water stream to at least about 138 degrees Celsius in a non-batch process to produce a heated water stream; maintaining the heated water stream at or above at least about 138 degrees Celsius for at least about two seconds; cooling the heated water stream to produce a cooled water stream; ultrafiltering the cooled water stream; and mixing dialysate components into the cooled water stream in a non-batch process.

  • Patent number: 9328969
    Abstract: Disclosed herein are small, lightweight, portable, systems that have the capability of reliably, reproducibly, highly efficiently and relatively inexpensively providing a source of purified water of sufficient volumes for home dialysis. In addition, the systems disclosed herein require much less purified water at any one time than the volumes typically needed for dialysis today, thereby further reducing the expense of running the system at home.
