Abstract
Systems and methods for delivery of fluid to a wound therapy dressing. In exemplary embodiments, a pressure sensor measures the pressure at the wound therapy dressing and restricts fluid flow to the wound therapy dressing when a predetermined pressure is achieve.
Claims20
An apparatus for use with a wound dressing, comprising:
- a controller operatively coupled to a fluid-flow device;
- wherein the controller is configured to:
- activate the fluid-flow device to provide fluid to the wound dressing until a predetermined pressure in a range of −10 mmHg to 0 mmHg at the wound dressing is reached.
A non-transitory computer-readable medium comprising executable instructions for performing steps in a method for delivering fluid to a wound dressing, wherein the executable instructions configure a controller to:
- send a first signal to a fluid-flow device to permit fluid flow to the wound dressing;
- determine a pressure at the wound dressing based on a signal received from a pressure sensor;
- and
- upon the pressure reaching a predetermined pressure, send a second signal to the fluid-flow device to restrict fluid flow to the wound dressing;
- wherein the predetermined pressure is in a range of −10 mmHg to 0 mmHg.

A system for providing wound therapy, comprising:
- a wound dressing in fluid communication with a negative-pressure source and a reservoir;
- a fluid-flow device fluidly coupled between the reservoir and the wound dressing;
- and
- a controller operatively coupled to the negative-pressure source and the fluid-flow device;
- wherein the controller is configured to activate the fluid-flow device to provide fluid from the reservoir to the wound dressing until a predetermined pressure in a range of −10 mmHg to 0 mmHg at the wound dressing is reached.
