Description

Technical Field

[0001] The utility model relates to the field of instruments for inputting medium into human body, in particular to a nasal oxygen tube for preventing air blockage. Background Art

[0002] The nasal oxygen cannula is a medical product made of soft polyvinyl chloride and silicone rubber. It is mainly composed of an air guide tube, an air guide branch and an oxygen outlet head. The detailed structure can refer to the patent application number "CN202221926124.9". Its main function is to introduce the oxygen in the oxygen concentrator into the human nasal cavity through the air guide tube, the air guide branch and the oxygen outlet head. The existing nasal oxygen cannula has a simple structure and is easy to use. However, it is precisely because the above structure is too simple that there are some problems when using it. The specific problems are as follows: The first is that when using the nasal oxygen cannula, the user is often lying down, and it is very easy to fall asleep when lying down. After falling asleep, the left and right turning of the body can easily press the main air guide tube under the body, and the existing nasal oxygen tube can be easily flattened. At this time, the problem of being unable to continue to supply oxygen will occur, which is very disadvantageous for the patient. Then there is another problem that the air guide branch tube of the existing nasal oxygen tube is hung on the ear, but there is generally no ear hanging mechanism designed in the middle of the air guide branch tube. In this case, the air guide branch tube is not very stable when hanging on the auricle. The air guide branch tube often falls off the auricle when the patient turns his head, and the air guide branch tube falling off the auricle can easily cause the oxygen head to slip out of the nasal cavity, which brings a bad experience to the user. Utility Model Content

[0003] The utility model aims to provide a nasal oxygen tube that prevents air blockage, solves the problem that the existing nasal oxygen tube is easily flattened when turning over and cannot continuously supply oxygen, and solves the problem that the existing nasal oxygen tube is unstable when hung on the auricle.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A nasal oxygen tube for preventing air blockage comprises an air guide main tube, an ear-hanging air guide branch tube and an oxygen outlet head, wherein the air inlet end of the ear-hanging air guide branch tube is connected to the air outlet end of the air guide main tube, the oxygen outlet head is arranged at the air outlet part of the ear-hanging air guide branch tube, the whole section of the air guide main tube is evenly provided with anti-pressure ring ribs, the anti-pressure ring ribs are arranged in the tube wall of the air guide main tube, and the spacing between the anti-pressure ring ribs is less than 2 cm; the middle part of the ear-hanging air guide branch tube is provided with an air bag type auricle hanging structure, and the outer side of the air bag type auricle hanging structure is provided with an air guide branch tube sleeve.

[0006] First, in this solution, anti-pressure ring ribs are evenly added throughout the entire length of the main air guide pipe. Through the support of the anti-pressure ring ribs, the main air guide pipe can be effectively prevented from being flattened. Since when a patient turns around, the contact area between the human body and the main air guide pipe is usually large, a simple anti-pressure ring rib can achieve a good anti-flattening effect. In addition, the air guide branch pipe in this solution is a hanging ear air guide branch pipe, that is, a hanging ear mechanism is provided in the middle of the air guide branch pipe. Therefore, it can be stably hung on the auricle, and it is not easy for the hanging ear air guide branch pipe to fall off the auricle when the patient turns his head. The patient experience is better. The airbag-type auricle hanging structure is light in weight, convenient to use, and has a certain pressure-bearing capacity.

[0007] As a further preference of the present utility model, limiting mechanisms are provided at both ends of the pipe sleeve through which the air guide branch pipe passes.

[0008] By adjusting the position of the limiting mechanism, the position of the airbag-type auricle hanging structure can be adjusted conveniently and quickly, so as to facilitate adapting to people with different face shapes.

[0009] As a further preference of the present utility model, the limiting mechanism includes a rubber limiting block. A pipe passing hole is provided in the middle of the rubber limiting block. The inner wall of the pipe passing hole is in contact with the outer wall of the hanging ear air guide branch pipe, and there is friction between the inner wall of the pipe passing hole and the outer wall of the hanging ear air guide branch pipe.

[0010] As a further preference of the present utility model, the front end of the main air guide pipe is connected to an oxygen generator connector through a transition connecting PVC pipe, and a sliding type gas flow regulator is provided in the middle of the transition connecting PVC pipe.

[0011] It is convenient to manually adjust the oxygen supply amount.

[0012] As a further preference of the present utility model, an air flow buffer cavity is externally connected to the oxygen outlet holes of the oxygen outlet head, and air outlet holes are evenly provided at the front end of the air flow buffer cavity.

[0013] The structure of the existing nasal oxygen tube at the oxygen outlet head is generally relatively simple. Many patients have reported that when oxygen enters the nostrils, the air flow is relatively rapid and it is uncomfortable to use. Therefore, after research, the oxygen outlet head has been improved, and an air flow buffer cavity is provided. When the air flow flows from the oxygen outlet holes of the oxygen outlet head into the air flow buffer cavity, it reaches a large space from a small space, so that the slow-flowing effect can be achieved, and then the air flow enters the nasal cavity from the air outlet holes.

[0014] Compared with the prior art, the present utility model can achieve at least one of the following beneficial effects:

[0015] 1. First, in this solution, anti-pressure ring ribs are evenly added throughout the entire length of the main air guide pipe. Through the support of the anti-pressure ring ribs, the main air guide pipe can be effectively prevented from being flattened.

[0016] 2. An ear hook mechanism is provided in the middle of the air guide branch pipe, so it can be stably hung on the auricle, and it is not easy for the air guide branch pipe with the ear hook to fall off the auricle when the patient turns his head, providing a better experience for the patient.

[0017] 3. By adjusting the position of the limiting mechanism, the position of the airbag-type auricle hanging structure can be adjusted conveniently and quickly, which is convenient for adapting to people with different face shapes.

[0018] 4. It is convenient to manually adjust the oxygen supply.

[0019] 5. An air flow buffer cavity is provided. When the air flow flows into the air flow buffer cavity from the oxygen outlet holes of the oxygen outlet head, it reaches a large space from a small space, which can play a role in buffering the air flow. Then the buffered air flow enters the nasal cavity from the air outlet holes, making it more comfortable. Description of the Drawings

[0030] Firstly, in this solution, anti-pressure ring ribs are uniformly added throughout the main air guiding pipe. Through the support of the anti-pressure ring ribs, the main air guiding pipe can be effectively prevented from being flattened. Because when the patient turns around, the contact area between the human body and the main air guiding pipe is usually large, so a simple anti-pressure ring rib can achieve a good anti-flattening effect. In addition, the air guiding branch pipe in this solution is an ear-hanging air guiding branch pipe, that is, an ear-hanging mechanism is arranged in the middle of the air guiding branch pipe. Therefore, it can be stably hung on the auricle, and it is not easy for the ear-hanging air guiding branch pipe to fall off the auricle when the patient turns his head, and the patient experience is better.
