An oximetry probe assembly includes fluid seal assembly taking the form of a manually actuated plunger which moves relative to a barrel having a seal placed therein. Depression of the plunger causes the seal to be deformed so as to permit insertion of an oximetry probe through the seal and advancement towards a central venous catheter. When the plunger is released, the seal is compressed against the barrel and the sheath of the oximetry probe to thereby form a fluid-tight seal. The plunger and barrel are preferably configured as a one-handed grasping assembly whereby the user may hold the plunger and barrel with one hand, press the plunger with the thumb, and advance the oximetry probe through the fluid seal assembly with the other hand.

L'invention concerne un ensemble sonde d'oxymétrie comprenant un ensemble joint à fluide prenant la forme d'un piston actionné manuellement qui se déplace par rapport à un fût dans lequel est placé un joint. L'enfoncement du piston provoque la déformation du joint de façon à permettre l'insertion d'une sonde d'oxymétrie à travers le joint et sa progression vers un cathéter veineux central. Lorsque le piston est relâché, le joint est comprimé contre le fût et la gaine de la sonde d'oxymétrie pour former ainsi un joint étanche aux fluides. Le piston et le fût sont de préférence configurés comme un ensemble pouvant être saisi d'une main, l'utilisateur pouvant ainsi tenir le piston et le fût d'une main, presser le piston avec le pouce et faire avancer la sonde d'oxymétrie à travers l'ensemble joint à fluide de l'autre main.
