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.

cavity-separating type nasal suction tube comprises a first pipeline, a second pipeline and a pipeline connector, wherein two lumens which are not communicated with each other are arranged inside the pipeline connector, the lumens are respectively matched with the respective air outlet ends of the first pipeline and the second pipeline in a splicing mode, two nasal suction tubes are arranged on the outer wall of the pipeline connector, each nasal suction tube is matched with one of the lumens, and the nasal suction tubes are matched with the nasal suction tubes in a communicated mode.
Specifically, the side walls of the air outlet ends of the first pipeline and the second pipeline are provided with air outlet holes, and the air outlet holes are communicated with the air inlet end of the nasal cavity suction tube.
Specifically, the inner end of the tube cavity is cylindrical, and the air outlet end of the first tube/the second tube is inserted into the inner end of the tube cavity.
Specifically, an air vent gap is reserved between the air outlet end of the first pipeline/the second pipeline and the inner end of the tube cavity, the air inlet end of the nasal cavity suction pipe is arranged between the air outlet end of the first pipeline/the second pipeline and the inner end of the tube cavity, and the air inlet end of the nasal cavity suction pipe is communicated with the air vent gap.
Specifically, the pipeline joint is in a straight pipe shape, a partition part is arranged inside the pipeline joint, and the partition part divides the inside of the pipeline joint into two pipe cavities which are not communicated with each other.
Specifically, the first pipeline, the second pipeline and the pipeline joint are all made of soft rubber materials.
Specifically, the outer wall of the pipe joint is fixedly provided with a gripping sheet.
Compared with the prior art, the invention has the beneficial effects that:
because the pipeline joint is internally provided with two pipe cavities which are not communicated with each other, the two pipe cavities are respectively in splicing fit with the respective air outlet ends of the first pipeline and the second pipeline, each pipe cavity is matched with one nasal cavity suction pipe, and the nasal cavity suction pipes are communicated with the pipe cavities matched with the pipe cavities, the conveying processes of the first pipeline and the second pipeline from respective storage containers (air sources) to the air outlets of the two nasal cavity suction pipes are mutually independent, one gas cannot reversely flow along the other pipeline to enter the storage container (air source) of the other gas, and the two gases are prevented from being mixed before use.

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 any combination of the embodiments or technical features described below can be used 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.
Specifically, with reference to fig. 3 to 5, the inner end of the lumen is cylindrical, and the air outlet end of the first/ second pipes 1, 2 is inserted into the inner end of the lumen. As the preferred technical scheme, when the air outlet end of the first pipeline 1/the second pipeline 2 is inserted into the inner end of the tube cavity, the air outlet 5 of the first pipeline 1/the second pipeline 2 is just aligned with the air inlet end of the nasal cavity suction tube 4 along the axial direction of the pipeline, so that the air outlet 5 can be communicated with the air inlet end of the nasal cavity suction tube 4 only by rotating the first pipeline 1/the second pipeline 2 relative to the pipeline joint 3 until the air outlet 5 is aligned with the air inlet end of the nasal cavity suction tube 4 along the circumferential direction of the pipeline. Because the end of giving vent to anger of first pipeline 1/second pipeline 2 inserts the inner end to the lumen, the effective area of contact of first pipeline 1/second pipeline 2 outer wall and lumen inner wall is great, and its connection reliability is higher.
Specifically, referring to fig. 5 and 7, the pipe joint 3 is in a straight pipe shape, a partition 32 is disposed inside the pipe joint 3, and the partition 32 divides the inside of the pipe joint 3 into two pipe cavities that are not communicated with each other.
Specifically, first pipeline 1, second pipeline 2 and pipe joint 3 are made by the flexible glue material, and as preferred, the inner wall profile of lumen is corresponding with first pipeline 1/2 outer walls of second pipeline, and the inner wall aperture of lumen slightly is less than the outer wall aperture of first pipeline 1/second pipeline 2 for first pipeline 1/second pipeline 2 can form interference fit with the lumen, with the improvement pipe connection reliability.
Specifically, the outer wall of the pipe joint 3 is fixedly provided with a grip piece 6, and the grip piece 6 can be gripped by a hand of a user.
