CA 2580223

A gastric tube placement device (10) having a carbon dioxide indicator (12) is disclosed. The carbon dioxide indicator (12) comprises a rectangular housing (18) defining a passageway (44) in communication with opposing ports (30, 32) that permits substantial axial flow through the passageway (44) with a carbon dioxide detector (17) disposed therein. A Y-port connector (16) having first and second legs (52, 54) in communication with a main port (56) with a gastric tube (14) coupled to the inside of the connector (16) is provided for insertion of the distal end of the gastric tube (14) through the esophagus of the patient. The carbon dioxide detector (17) is disposed inside the rectangular housing (18) which is configured to minimize the dead space inside the housing (18) and facilitates a substantially axial airflow through the passageway (44) when a syringe or similar air~-evacuating device (50) is engaged to the rectangular housing (18) and draws air from the housing(18).

L~invention concerne un dispositif de mise en place de tube gastrique (10) doté d~un indicateur de dioxyde de carbone (12). L~indicateur de dioxyde de carbone (12) comprend un boîtier rectangulaire (18) définissant un passage (44) en communication avec des orifices opposés (30, 32) permettant un écoulement sensiblement axial à travers le passage (44) et contenant un détecteur de dioxyde de carbone (17). Un connecteur à orifice en Y (16) comportant des première et deuxième pattes (52, 54) en communication avec un orifice principal (56) et sur l~intérieur duquel est couplé un tube gastrique (14) permet l~insertion de l~extrémité distale du tube gastrique (14) à travers l~AEsophage d~un patient. Le détecteur de dioxyde de carbone (17) disposé à l~intérieur du boîtier rectangulaire (18) est configuré pour minimiser l~espace inutilisé à l~intérieur du boîtier (18) et favorise un écoulement d~air sensiblement axial à travers le passage (44) lorsqu~une seringue ou un dispositif d~évacuation d~air similaire (50) s~engage avec le boîtier rectangulaire (18) et aspire de l~air du boîtier (18).
