A suction catheter has a distal end portion with an opening for insertion into a patient's airway. The proximal end portion is attached to a resilient tubular member on which an external valve mechanism can operate to prevent fluid flow through the member. The valve mechanism is biased to a normally closed condition, will open the tubular member when depressed, and will return to its normally closed condition when not depressed. A downstream connector can be attached to a source of suction. The invention is more comfortable for the patient, uses fewer components and is less expensive than prior art suction catheters.

Un cathéter à succion, destiné à être inséré dans les voies respiratoires d'un patient, comporte une terminaison distale munie d'une ouverture. Sa partie proximale est jointe à un tube élastique relié à une valve permettant de contrôler l'écoulement d'un fluide dans ce tube. Dans son mode de fonctionnement habituel, la valve maintient le tube fermé, l'ouvre lorsqu'elle est actionnée et le referme lorsque l'action est interrompue. Un appareil de succion peut être couplé au système par le biais d'une connexion située en aval. L'invention compte moins de composantes, elle est moins coûteuse à réaliser que les cathéters à succion de l'art antérieur et son utilisation présente moins d'inconfort pour le patient.
