Closed wound suction evacuator with rotary valve

A medical evacuator system for evacuating fluids from the body comprising in combination:

• (a) a closed compressible container having top and bottom portions connected by a flexible sidewall, said container adapted to be compressed and to expand to develop a vacuum on expansion;
• (b) a valve means comprised of a valve turret which includes an inlet orifice to provide communication between the interior of said container and a drainage tube and a vent orifice to provide communication between the interior of said container and the atmosphere, and a circular collar which telescopically and sealingly surrounds said valve turret adapted to selectively close off and seal said inlet orifice and vent orifice, said valve turret having an upper and lower portion, said upper portion containing said inlet orifice and said vent orifice, and wherein said circular collar surrounds over said upper portion of said valve turret, the interior of said circular collar communicating with a hollow drainage orifice inlet nipple and a hollow orifice outlet nipple, said circular collar is capable of rotation on the upper portion of the valve turret such that the orifice inlet nipple may be aligned with the inlet orifice of the upper portion of the valve turret or the orifice outlet nipple may be aligned with the vent orifice, or both the inlet orifice and vent orifice may be closed off and sealed by the inner wall surface of the circular collar, or the orifice inlet nipple may be aligned with the vent orifice at the same time the orifice outlet nipple is aligned with the inlet orifice;
• the upper turret portion includes a top, said top having indicated thereon toward the peripheral edge of the top, designations for four positions:
• patient position, hold position, activate position, and a wall suction position, wherein the activate position is disposed at a radial angle from the patient position in one direction and the wall suction position is disposed at a radial angle from the patient position in the opposite direction, and the hold position is located about midway between the patient and activate positions, and wherein said inlet orifice in said upper turret portion is aligned with the patient position and said vent orifice in said upper turret portion is aligned with said wall suction position, and is at a certain radial distance apart from said inlet orifice, and wherein the circular collar orifice outlet nipple is disposed in the outer surface of said circular collar and is disposed radially apart at said certain radial distance from said circular collar orifice inlet nipple, and wherein said inlet nipple has on the top thereof, a valve indicator for selectively positioning the circular collar on the valve turret upper portion, and wherein the patient position is disposed at a radial angle of about 140.degree. clockwise from the wall suction position and the activate position is disposed at a radial angle of about 80.degree. clockwise from the patient position, and the hold position is located midway between the patient and activate positions at a radial angle of about 40.degree. from each, and wherein said outlet nipple is disposed about 140.degree. radially clockwise from said inlet nipple.
