Abstract

A system for testing a negative pressure wound dressing, includes a simulated wound having a housing and a wound cavity within the housing, and having a shape and dimension representative of an actual wound type, a wound dressing positionable at least over the simulated wound, a negative pressure source in fluid communication with the wound cavity, at least one sensor adapted to record at least one parameter within the simulated wound, an air leak model including a valve in fluid communication with the wound cavity whereby opening of the valve simulates an air leak within the wound cavity, a fluid source in fluid communication with the wound cavity for delivering fluid to the wound cavity to simulate presence of exudates and a computer coupled to the at least one sensor for recording and analyzing data recorded by the at least one sensor to thereby providing an indication of functioning of the system.

Claims

1. A testing system for testing a negative pressure wound therapy apparatus of the type including a wound dressing adapted for positioning over a wound and a negative pressure source, the testing system comprising:

a simulated wound having a housing and a wound cavity within the housing, the wound cavity having a shape and dimension representative of an actual wound type, and adapted to accommodate the wound dressing of the negative pressure wound therapy apparatus positioned there over;

a negative pressure conduit fluid communication with the wound cavity and connectable to the negative pressure source of the negative pressure wound therapy apparatus; and

at least one sensor adapted to record at least one parameter within the simulated wound.

2. The testing system according to claim 1 including an air leak model having a valve in fluid communication with the wound cavity whereby opening of the valve simulates an air leak within the wound cavity.

3. The testing system according to claim 1 including a fluid source in fluid communication with the wound cavity for delivering fluid to the wound cavity to simulate presence of exudates.

4. The testing system according to claim 1 including a computer coupled to the at least one sensor for recording and analyzing data recorded by the at least one sensor to thereby providing an indication of functioning of the system.
