Abstract
The described invention is a negative pressure wound therapy device designed for easy application to small to large wounds. The negative pressure device piece applies a vacuum to a wound and absorbs excess exudate or moisture. The negative pressure device comprises a sensor, battery, and small PCBA to monitor the pressure in the dressing and to alert a user when the dressing needs to be changed.
Claims18
A negative pressure wound therapy device comprising:
- a dressing comprising a drape and a contact layer;
- a pump coupled to the drape, wherein the pump comprises a power source, an air inlet in fluidic communication with the contact layer, and an air outlet and the pump, in operation, creates a sub-atmospheric pressure in a region formed by the drape, the contact layer, and the air inlet when the contact layer is affixed to wounded skin;
- and
- a pressure sensor, wherein the pressure sensor triggers an alert that the dressing requires changing when the pressure in the region reaches a predetermined threshold.
