ABSTRACT:
The invention relates to a sputum trap for an aspiration a respiratory support system which includes a sleeved suction catheter device, a suction control valve, and a ventilator manifold. The sputum trap allows collection of sputum directly from a patient through a suction catheter without causing a loss of PEEP in the respiratory support system. The sleeved suction catheter device includes a sputum trap/suction control valve end connector having a valve therein which prevents air flow through the catheter until the sputum trap or suction control valve is attached thereto. The manifold includes a one-way check valve which is opened upon insertion of the manifold end connector of the sleeved suction catheter therein. The suction control valve includes an actuator which is linearly movable between a first position in which suction therethrough is prevented, to a second position in which the valve is open to suction therethrough. The manifold includes an access port for attachment and detachment of the sleeved suction catheter thereto without interruption of continuous respiratory support of the patient. The access port has a normally closed valve therein which remains closed regardless of the pressure changes within the manifold. The normally closed valve is positioned in the port such that placement of the manifold connector of the sleeved suction catheter device therein forces the normally closed valve to an open position. The sputum trap is designed for quick connect and disconnect with the sleeved suction catheter device and the suction control valve, and for simplified sealing for subsequent transport after having been used to collect a sputum sample from a patient.
