Abstract
The present disclosure sets forth an automated peritoneal dialysis (“PD”) system, which enables the re-use of certain disposable components. The APD system includes a sterilization source, such as a steamer or a UV radiation light source that sterilizes a disposable filter. During therapy, the disposable filter is connected to a PD fluid line and to a patient's catheter. Post-therapy, the disposable filter is disconnected from the patient's catheter, but remains connected to the PD fluid line, and the disposable filter undergoes steam or UV radiation sterilization.
Claims20
A disinfection system of an automated peritoneal dialysis (“APD”) system comprising:
- an APD cycler comprising:
- a fluid pump,
- an inline heater positioned downstream from a source of fresh PD solution and arranged to heat the fresh PD fluid,
- a fluid line in communication with the source of fresh PD solution, the inline heater, and the fluid pump, and
- a control unit;
- a sterilization chamber;
- a sterilization source housed in the sterilization chamber;
- and
- a patient catheter line in communication with a disposable microbial filter and a patient, wherein the disposable microbial filter is detachably connectable to the patient catheter line, and wherein the disposable microbial filter is configured to be placed in the sterilization chamber during a sterilization process.
A disinfection system of an automated peritoneal dialysis (“APD”) system comprising:
- an automated peritoneal dialysis (“APD”) cycler comprising:
- a fluid line,
- a fluid pump configured to pump fluid through the fluid line from a fluid source;
- a disposable filter in fluid communication with the fluid line, wherein the disposable filter comprises:
- a primary filter comprising a first chamber and a second chamber,
- a bypass cap configured to route the fluid from the first chamber to the second chamber to form a circulation loop with the disposable filter and the APD cycler;
- and
- a sterilization chamber configured to house the disposable filter.
