An improved respiratory suction apparatus (300) catheter includes a manifold for attachment to the distal hub of an endotracheal tube to form a respiration circuit, a catheter tube (308) which is displaceable through the manifold (304) and into the endotracheal tube to suction secretions from the tube and lungs, and a valve mechanism (358) disposed adjacent the respiration circuit to minimize the draw of air from the respiration circuit of a patient while the catheter tube (308) is being cleaned. In a preferred embodiment of the invention, the catheter tube (308) is cleaned more thoroughly than in the prior art while simultaneously drawing little or no air from the patient's respiration circuit.

L'invention concerne un appareil respiratoire (300) à cathéter d'aspiration amélioré qui comprend un collecteur destiné à être fixé au bout distal d'un tube trachéal, de manière à former un circuit respiratoire, un tube de cathéter (308) pouvant être déplacé dans le collecteur (304) et à l'intérieur du tube trachéal pour aspirer les sécrétions depuis le tube et les poumons, et un mécanisme de valve (358) adjacent au circuit respiratoire pour réduire au minimum l'aspiration d'air depuis le circuit respiratoire d'un patient lorsque le tube de cathéter (308) est en cours de nettoyage. En mode de réalisation préféré, le tube de cathéter (308) peut être nettoyé plus efficacement qu'avec les moyens techniques existants et, simultanément, on aspire peu ou pas d'air depuis le circuit respiratoire du patient.
