Abstract

Process and apparatus for quickly removing contaminated tissue and blood from a localized skin wound in the body of a human being immediately after contamination has occured by removing all of the tissue from the wound by use of a biopsy punch and removing the contaminated blood from the wound by suction from a vacuum pump.

Claims

1. Apparatus for quickly removing contaminated tissue and blood from a localized skin wound of the body of a human being immediately after contamination has occurred, said apparatus comprising:

a biopsy punch for removing all the tissue from the wound;

first hose conduit means having one end connected to second means for having suction tight engagement with the wound and having an opposite end adapted to receive a force of suction, the second means including a plurality of separate elements, each one of said elements being adapted for detachable suction engagement with the body to treat a correspondingly different type of body wound, and a valve having a like plurality of input ports, each valve input port being connected to a corresponding element, the valve having a single output port connected to the one end of the first hose means, the valve being manually operable to select any one of the elements and to connect the selected one of the elements to the first hose means; and

third means for producing said force of suction, the third means including a vacuum pump having an inlet port connected to the other end of the first means and having an outlet port, the contaminated blood from the wound being removed by suction through the selected element, the valve, the first hose means, and the pump and being discharged at the outlet port of the pump.

2. The apparatus of claim 1 further comprising:

a wheeled cart supporting the first, second and third means, said cart also supporting a dc to ac power inverter, a dc power supply and an explosion proof motor, the motor being coupled to said pump, the supply being coupled through the inverter to the motor.

3. The apparatus of claim 1 wherein there are four elements, a first element being a finger/thumb suction thimble, a second element being an attachment for treating scratches or cuts, a third element being a funnel attachment, a fourth element being an arm attachment.

4. The apparatus of claim 1 further including a first filter connected between the valve output port and the one end of the first hose means.

5. The apparatus of claim 4 further including a second filter connected between the outlet port of the pump and a point of discharge.
