Abstract:
1. An irrigator port for a phlegm suction tube to fit two injectors having different mating structures, comprising: a tube body, being hollow, a coupling end being formed at one end of the tube body and a connecting end being formed at the other end of the tube body; a check valve having a valve head protruding out of the coupling end after the check valve is disposed in the coupling end, wherein the valve head is formed at one end of the check valve, and a recess is formed at the other end of the check valve; a spring with one end disposed inside the recess so that the check valve is elastically pushed by the spring; and a tube connector, coaxially connected to the coupling end of the tube body, having a joint portion surrounding the valve head, wherein the joint portion has a passage communicating with the tube body, and the check valve flexibly closes the passage from the tube body; wherein a diameter of the passage fits a first injector with a first mating structure, and an outer diameter of the joint portion fits a second injector with a second mating structure, and wherein after a nozzle of the first injector or the second injector is engaged with the tube connector to push the valve head out of the passage and being located inside the tube body, a chemical agent in the first injector or the second injector flows out of the nozzle and around an outer surface of the check valve towards the connecting end.
