Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
161 words
In a method for irrigating a wound and/or abrasion with a wound cleansing aqueous saline solution of approximately 0.9% w/v dispensed from a hand-held aerosol container with the liquid wound cleansing solution disposed therein and to be dispensed through a manually operable valve, providing a propellant in the container which provides a pressure for propelling the wound cleansing solution through the valve, sizing the valve and selecting the pressure whereby when the manually actuated valve is activated, it provides 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 grasping the container with the hand, actuating the valve with the same hand and positioning the hand with the container therein to direct the stream of wound cleansing solution coming from the valve toward the wound or abrasion to irrigate and cleanse the wound and/or abrasion.
Claim 2
Dependent Claim
161 words
In a method for irrigating a wound and/or abrasion with a wound cleansing aqueous saline solution of approximately 0.9% w/v dispensed from a hand-held aerosol container with the liquid wound cleansing solution disposed therein and to be dispensed through a manually operable valve, providing a propellant in the container which provides a pressure for propelling the wound cleansing solution through the valve, sizing the valve and selecting the pressure whereby when the manually actuated valve is activated, it provides 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 grasping the container with the hand, actuating the valve with the same hand and positioning the hand with the container therein to direct the stream of wound cleansing solution coming from the valve toward the wound or abrasion to irrigate and cleanse the wound and/or abrasion.
Claim 3
Dependent Claim
23 words
A method as in claim 1 together with the step of providing a pressure on the wound cleansing solution ranging from 60-100 psig.
Claim 4
Dependent Claim
40 words
A method as in claim 1 wherein the liquid wound cleansing solution is disposed in a collapsible pouch, wherein the collapsible pouch is disposed in a container and wherein the propellant is disposed in the container outside the collapsible pouch.
Claim 5
Dependent Claim
140 words
In a method for irrigating a wound and/or abrasion with a wound cleansing aqueous saline solution of approximately 0.9% w/v dispensed from a hand-held self-contained container having a finger-actuated valve thereon, placing the liquid wound cleansing solution in the container and providing a propellant in the container, sizing the valve and selecting the pressure so that when the valve is operated it provides a stream of wound cleansing solution which is substantially equivalent in volume and pressure to that generated by a hand-held 30 to 60 milliliter syringe having an 18 gauge needle mounted thereon, picking up and grasping the container in one hand, operating the valve with a finger of said one hand and positioning said one hand to direct the stream of wound cleansing solution into the wound and/or abrasion to irrigate and cleanse the wound and/or abrasion.
Claim 6
Dependent Claim
140 words
In a method for irrigating a wound and/or abrasion with a wound cleansing aqueous saline solution of approximately 0.9% w/v dispensed from a hand-held self-contained container having a finger-actuated valve thereon, placing the liquid wound cleansing solution in the container and providing a propellant in the container, sizing the valve and selecting the pressure so that when the valve is operated it provides a stream of wound cleansing solution which is substantially equivalent in volume and pressure to that generated by a hand-held 30 to 60 milliliter syringe having an 18 gauge needle mounted thereon, picking up and grasping the container in one hand, operating the valve with a finger of said one hand and positioning said one hand to direct the stream of wound cleansing solution into the wound and/or abrasion to irrigate and cleanse the wound and/or abrasion.
Claim 7
Dependent Claim
41 words
A method as in claim 4 together with the step of placing the wound cleansing solution in a collapsible pouch in the container with the propellant surrounding the pouch whereby the stream can be provided in any position of the container.
Claim 8
Dependent Claim
25 words
A method as in claim 4 in which the wound cleansing solution is dispensed at a minimum rate of about four cubic centimeters per second.
