COAXIAL AND DOUBLE LUMEN BREATHING CIRCUIT SYSTEMS HAVING A LUNG PRESSURE MEASUREMENT PORT AND CLOSED SYSTEM WATER TRAP WHICH CAN BE DRAINED WITH AN ENJECTOR
Double lumen breathing circuits and coaxial breathing circuits which at present do not comprise water traps, by adding a closed system water trap (1, 2) designed to have an inkwell shape (6) and a lung pressure measurement port (9) to said circuits wherein the fluid collected in the bottle section (4) can be discharged without having to open the bottle by means of a drainage luer port (5) located at the base of the bottle and a needleless apparatus (15) that has been inserted into the port, and an injector.
