1. A medical dressing comprised of:
- a flexible body attaching means with a topside and an underside;
said body attaching means having a center opening, wherein said body attaching means is drawn into a flexible duct segment extending in the direction of said topside of said body attaching means, said flexible duct segment being generally tubular and having an interior and an exterior side; and
a flexible single walled one-way valve tube having an interior and an exterior side, a portion of said interior side at a first end of said one-way valve tube is sealed to said exterior side of said flexible duct segment of said body attaching means for enabling passage of air in substantially one direction from said flexible duct segment through said one-way valve tube.

6. A medical dressing comprised of:
-
a flexible, impermeable body attaching means with a top-side, and an underside, said flexible impermeable body attaching means having a center opening drawn into a flexible impermeable duct segment extending in the direction of said top-side of said flexible impermeable body attaching means, said flexible impermeable duct segment being generally tubular and having an interior and an exterior side, said flexible body attaching means further comprising a non-adhesive finger hold, said underside of said flexible body attaching means is covered by a double-sided adhesive material, said portion of said underside of said body attaching means covered by said double-sided adhesive being attached to a tear-away backing, said tear-away backing having a corresponding finger hold adjacent to said finger hold of said body attaching means for assisting in removing said tear-away backing from said underside of said body attaching means; a flexible, single walled impermeable one-way valve tube having an interior and an exterior side, a portion of said interior side at a first end of said one-way valve tube is sealed to said exterior side of said flexible duct segment of said body attaching means for enabling passage of air in substantially one direction from said flexible duct segment through said one-way valve tube; said flexible, single walled one-way valve tube further comprising a second end with two collapsible walls; said second end being opposite said first end of said one-way valve tube attached to said flexible duct segment; and said collapsible walls of said one-way valve tube being in a collapsed position when the patient inhales so as to prohibit air from penetrating into the patient'"'"'s pleural space through the wound hole and in a non-collapsed position when said patient exhales to allow air from said patient'"'"'s pleural space to be expelled through said flexible one-way valve tube.

7. A non-invasive method of evacuating accumulated fluid and air from the pleural space of a patient with a chest wound, comprising the steps of:
-
positioning over said patient'"'"'s wound hole a medical dressing comprised of a flexible body attaching means having a center opening drawn into a flexible duct segment, said duct segment attached to a flexible, single walled one-way valve tube such that exhaled air passes from said patient'"'"'s wound hole through said flexible duct segment and said flexible one-way valve tube in substantially one direction; securing said medical dressing to the skin of said patient surrounding said wound hole; inserting suction means into said flexible, single walled one-way valve and said flexible duct segment to a position directly over said wound hole; securing disposal means to said suction means; and engaging said suction means to suck said accumulated fluid and air from said pleural space into said disposal means attached to said suction means. - View Dependent Claims (8)

9. A method of treating a tension pneumothorax, comprising the steps of:
-
inserting a catheter into the side of the chest of the patient having a wound hole to allow for trapped air to be expelled from the pleural space of said patient; positioning over said catheter a medical dressing comprised of a flexible body attaching means having a center opening drawn into a flexible duct segment, said flexible duct segment attached to a flexible, single walled one-way valve tube to protect said catheter from moving in a manner detrimental to said patient; and securing said medical dressing to the skin of said patient surrounding said catheter.
