Abstract
Apparatus for applying negative pressure therapy to a wound site, which comprises an open celled foam pad for application to the wound, a suction tube connecting the foam pad to a collection canister having a shut-off valve which closes the outlet from the canister when it is full, a tube for connecting the canister to a wall suction point or to a vacuum bottle, and a pressure detecting device connected to the suction tube between the foam pad and the canister for indicating when the pressure in the suction tube falls below a predetermined level.

Apparatus for applying negative pressure therapy to a wound site, which comprises an open celled foam pad for application to the wound site, a suction tube connecting the foam pad to a collection canister, said canister having a shut-off valve which closes an outlet from the canister in response to the collection canister being full, a tube connecting the canister to a wall suction point, and a pressure detector connected to the suction tube between the foam pad and the canister for indicating when the pressure in the suction tube crosses a predetermined level.
Apparatus for applying negative pressure therapy to a wound site, which comprises an open-celled foam pad for application to the wound site, a suction tube connecting the foam pad to a collection canister, a tube connecting an outlet of the canister to a wall suction point, a sensor operable to detect when the canister is full, and a shut-off valve fluidly connected to the outlet of the canister to close the outlet in response to the collection canister being full.
Apparatus for applying negative pressure therapy to a wound site, the apparatus comprising:
- an open-celled foam pad for application to the wound site;
- a suction tube connecting the foam pad to a collection canister;
- a pressure regulator fluidly connected between the canister and a wall suction point;
- and
- a processor in electronic communication with the pressure regulator to regulate the pressure from said wall suction point to the collection canister.
