ABSTRACT:
A closed system suction catheter has a catheter enclosed within a flexible envelope secured between a patient end fitting and a machine end fitting. The patient end fitting has a cleaning chamber with a valve at its patient side and is normally closed so that the cleaning chamber is isolated from the patient. The valve has an outer rigid housing enclosing a one-piece elastomeric moulding of tubular shape. The elastomeric moulding has two pads projecting externally through openings in the outer housing. The elastomeric moulding also has a web extending internally across its diameter with a diametrically-extending slit aligned with the pads. A collar mounted on the housing is slidable along the housing to engage the pads so as to apply pressure across the web and open the slit, thereby allowing the catheter to be advanced to the patient.
