ABSTRACT:
A compact vacuum therapy system useful in the treatment of male sexual dysfunction is provided which includes a pump body which is designed for removable mounting on a tube in both storage and operational positions. The pump body includes a reciprocable piston having a circumscribing groove of a width to permit axial shifting of an O-ring sealing member therewithin during movement of the piston within the pump body. The shifting sealing member thus acts as a valve to alternately seal and open a slot defined in the piston transverse to the groove during the reciprocating strokes of the piston. The piston is axially oriented with the intake and the tube when the pump body is mounted to the tube.
