Abstract
Method for irrigating a wound and/or abrasion with a liquid wound cleansing solution dispensed from a hand-held container with the liquid wound cleansing solution disposed therein and to be dispensed through a manually operable valve. The method includes the steps of providing a propellant in the container which provides a pressure for propelling the wound cleansing solution through the valve, actuating the manually actuated valve to provide a stream of liquid wound cleansing solution which is substantially equivalent in volume and in pressure to that generated by a human hand-held 30 to 60 milliliter syringe having an 18 gauge needle mounted thereon and directing the stream toward the wound or abrasion to irrigate and cleanse the wound and/or abrasion.
