Abstract
Apparatuses, systems, and methods for optimizing fluid storage in a negative pressure therapy system are described. A fluid storage canister includes a first section, a second section, a fluid flow pathway, and a forced air module. The first section is fluidly coupled to a dressing and stores fluid, and the second section is fluidly coupled to a therapy unit and stores fluid. The fluid flow pathway is disposed between the first section and the second section. The forced air module generates a fluid flow through the fluid flow pathway.
Claims17
A canister comprising:
- a first section configured to be fluidly coupled to a dressing and to store fluid;
- a second section configured to be fluidly coupled to a therapy unit and to store fluid;
- a fluid flow pathway disposed between the first section and the second section;
- a forced air module configured to generate a fluid flow through the fluid flow pathway;
- and
- a pressure sensor disposed within the fluid flow pathway, wherein the pressure sensor is configured to cover an opening in the fluid flow pathway to allow the pressure sensor to sense pressure in the canister and the pressure sensor is electrically coupled to the forced air module and is configured to control the forced air module based on a pressure sensed in the canister.
