The invention relates to a suction catheter device usable with a respiratory support system which includes a catheter enveloped in a sleeve having a proximal end connector for connection to a suction source through a suction control device such as a suction control valve, and a distal end connector for attachment to a manifold of the respiratory support system. The proximal end connector includes a normally closed valve therein which prevents air flow through the catheter until a suction control device is attached thereto. The proximal end connector may also be adapted for use on a dual lumen catheter and thereby include a fluid injection passage having a one-way check valve therein. The distal end connector of the suction catheter device includes a magnifying window through which a portion of the catheter within the connector can be viewed. The catheter includes one or more markings thereon which indicate the relative position of the catheter and the connector, and which can be viewed through the magnifying window of the connector to indicate to the medical worker how far the catheter has been inserted into the patient's trachea or lungs. The invention also includes the method of assembly of the suction catheter device and the method of use thereof in conjunction with the respiratory support system.

[ We claim:] [1.] A suction catheter device for use with a respiratory support system including a ventilator and a suction source, said device comprising:a catheter having a proximal end and a distal end;a distal end connector slidably attached to said catheter for connecting said catheter device to a ventilator of a respiratory support system;a proximal end connector fixedly attached to said proximal end of said catheter for connecting said suction catheter device to a suction source; andsaid proximal end connection including a normally closed valve for preventing fluid flow through said catheter when said proximal end connector is not attached to a suction source, and for allowing fluid flow through said catheter when said proximal end connector is attached to a suction source, said normally closed valve automatically being placed in an open position responsive to said proximal end connector being engaged to a suction source.
