Abstract
Some embodiments are directed to a system 10 for the application of topical negative pressure therapy to a site 18 on the body of a mammal. Some embodiments of the system 10 comprise a piston 22 and cylinder 24 device 12 having a self-contained power source for the generation of a reduced pressure and for aspirating the site 18. Some embodiments of the system 10 comprise a dressing 14 sealably surrounding the site 18 that can be operably connected to the device 12 by a conduit means 16 to apply the reduced pressure to the site 18.
Claims6
A negative pressure therapy system, comprising:
- a suction device comprising a suction chamber including a slidable piston therein, wherein the slidable piston is configured to generate a negative pressure in the suction chamber;
- a dressing configured to be positioned at a wound site and to communicate the negative pressure from the suction chamber to the wound site;
- a first pressure sensor configured to be in communication with the dressing at the wound site and to detect a first pressure at the dressing at the wound site;
- and
- a second pressure sensor configured to be in communication with the suction chamber and to detect a second pressure in the suction chamber.
