  • Publication number: 20220313882
    Abstract: The present disclosure relates to an automated peritoneal dialysis (APD) system using gravity to deliver fluid from one or more source dialysate bags to the patient as the destination. The present disclosure further relates to a load cell protection assembly that prevents the load cells associated with the delivery of fluid in the system from experiencing an overload condition in either the down direction or the up direction, while maximizing safety and efficiency of the system while minimizing excess cost and complexity.

  • Publication number: 20200261638
    Abstract: An automated peritoneal dialysis (APD) system using gravity to deliver fluid from one or more source dialysate bags to the patient as the destination, and using gravity to deliver fluid from the source patient to the destination drain container or drain receptacle, and heats at least one dialysate bag placed onto a heated plate, and using a disposable tubing set is used for dialysate delivery to and from the patient, and using one or more solenoid-operated, normally closed, electronically-controlled pinch valves which pinch or release the disposable tubing set's tubing to stop or start fluid flow, respectively.
