An improved respiratory suction apparatus catheter (200) comprising a manifold (204) for attachment to the distal hub of an endotracheal tube to form a ventilation circuit, a catheter tube (208) which is displaceable through the manifold (204) and into the endotracheal tube to suction secretions from the tube and lungs, and a valve mechanism disposed adjacent the ventilation circuit to minimize the draw of air from the ventilation circuit of a patient while the catheter is being cleaned. In a preferred embodiment of the invention, the catheter (208) is cleaned more thoroughly than in the prior art while simultaneously drawing little or no air from the patient's ventilation circuit.

L'invention concerne un cathéter d'aspiration amélioré (200) qui comprend un collecteur (204) destiné à être fixé sur l'embout distal d'une sonde de ventilation trachéale de façon à former un circuit de ventilation, un cathéter (208) pouvant être introduit par ledit collecteur (204) dans ladite sonde de façon à aspirer les sécrétions provenant de la sonde et des poumons, et un mécanisme clapet, disposé adjacent au circuit de ventilation de façon à minimiser la quantité d'air prélevée dans le circuit de ventilation d'un patient pendant le nettoyage du cathéter. Dans un mode de réalisation préféré, le cathéter (208) peut être nettoyé plus à fond que les cathéters existants, tout en prélevant peu ou pas d'air dans le circuit de ventilation du patient.
