Background

In the course of treatment or health care, it is sometimes necessary to mix two gases, i.e. during anesthesia: in order to facilitate the control of the amount of anesthetic gas, the anesthetic gas (nitrous oxide) and the oxygen required for breathing are separately delivered to the patient without having to store the nitrous oxide and the oxygen mixed in advance. As another example of the hydrogen treatment process: because the mixed hydrogen and oxygen is dangerous to store, the hydrogen used for treatment or health care and the oxygen needed for breathing are respectively delivered to the patient, and the mixed hydrogen and oxygen cannot be stored in advance. Two separate conduits are required for the delivery of the two gases, and in the prior art, the two conduits are connected at their output ends, and in certain unexpected situations, one of the gases may flow in a reverse flow along the other conduit into a container for the other gas, causing the two gases to mix before use, thereby interfering with subsequent use or presenting a hazard.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

Referring to fig. 1 to 7, the nasal suction tube comprises a first tube 1, a second tube 2 and a tube connector 3. Two pipe cavities (refer to fig. 5 and 7) which are not communicated with each other are arranged inside the pipe joint 3, and the two pipe cavities are respectively in inserting fit with the respective air outlet ends of the first pipeline 1 and the second pipeline 2. Two nasal suction pipes 4 are arranged on the outer wall of the pipeline joint 3, and the two nasal suction pipes 4 are respectively used for being inserted into two nostrils of a nose. Each lumen is matched with a nasal suction tube 4, and the nasal suction tube 4 is communicated with the matched lumen.

Because the pipeline joint 3 is internally provided with two non-communicated pipe cavities (refer to fig. 5 and 7), the two pipe cavities are respectively in inserted connection and matching with the respective air outlet ends of the first pipeline 1 and the second pipeline 2, each pipe cavity is matched with one nasal cavity suction pipe 4, and the nasal cavity suction pipes 4 are communicated with the pipe cavities matched with the pipe cavities, the conveying processes of the first pipeline 1 and the second pipeline 2 from respective storage containers (air sources) to the air outlet parts of the two nasal cavity suction pipes 4 are mutually independent, one gas cannot reversely flow into the other storage container (air source) of the other gas along the other pipeline, and the two gases are prevented from being mixed before use.

Specifically, with reference to fig. 3 and 4, the side walls of the air outlet ends of the first pipeline 1 and the second pipeline 2 are both provided with air outlet holes 5, and the air outlet holes 5 are communicated with the air inlet end of the nasal suction tube 4.
