Abstract
Systems and methods for purging a negative pressure wound therapy system.
Claims24
A system for purging a negative pressure wound therapy system, the system comprising:
- a negative pressure source comprising an inlet and an outlet, wherein:
- the inlet is configured for fluid communication with a wound therapy dressing via a first conduit;
- and
- the outlet is configured for fluid communication with the wound therapy dressing via a second conduit;
- and
- a diverter valve coupled to the second conduit, wherein the diverter valve is configured to allow a fluid flow from the negative pressure source to atmosphere when the diverter valve is in a first position, wherein the diverter valve is configured to prevent fluid flow from the negative pressure source to the wound therapy dressing through the second conduit when the diverter valve is in the first position, and wherein the diverter valve is configured to allow a fluid flow from the negative pressure source to a wound therapy dressing through the second conduit when the diverter valve is in a second position.

A method of purging a negative pressure wound therapy system, the method comprising:
- operating a negative pressure source coupled to a wound therapy dressing, wherein:
- the negative pressure source comprises an inlet and an outlet;
- the inlet is in fluid communication with the wound therapy dressing via a first conduit;
- the outlet is in fluid communication with the wound therapy dressing via a second conduit;
- the second conduit is in fluid communication with a diverter valve;
- the diverter valve is configured to allow a fluid flow from the negative pressure source to atmosphere when the diverter valve is in a first position;
- the diverter valve is configured to prevent fluid flow from the negative pressure source to the wound therapy dressing through the second conduit when the diverter valve is in the first position;
- and
- the diverter valve is configured to allow a fluid flow from the negative pressure source to the wound therapy dressing through the second conduit when the diverter valve is in a second position;
- operating the negative pressure source to provide a negative pressure at the wound therapy dressing with the diverter valve in the first position;
- and
- manipulating the diverter valve from the first position to the second position.

A system for purging a negative pressure wound therapy system, the system comprising:
- a reservoir;
- a negative pressure source comprising an inlet for negative pressure and an outlet for positive pressure, wherein:
- the inlet is configured for fluid communication with a wound therapy dressing via a first conduit and the reservoir;
- and
- the outlet is configured for fluid communication with the wound therapy dressing through the reservoir via a second conduit;
- and
- a diverter valve directly coupled to the outlet and coupled to the second conduit, wherein the diverter valve is configured to allow a fluid flow from the outlet to atmosphere when the diverter valve is in a first position, wherein the diverter valve is configured to prevent fluid flow from the negative pressure source to the wound therapy dressing through the second conduit when the diverter valve is in the first position, and wherein the diverter valve is configured to allow a fluid flow from the outlet to the wound therapy dressing through the second conduit when the diverter valve is in a second position.
