New description: [New technical field] This creation department has a gas supply structure for the air supply nasal tube, especially for the air supply structure of the air supply tube for the gas supply at the nasal cavity, 疋0 species for 1 .. Built to reduce the use of nasal endometrial damage in patients. [Prior Art] • At present, in order to increase the oxygen content of the patient during inhalation or the sputum, the sputum will be inserted into the nasal cavity of the patient. The general air supply nasal tube is as shown in Figures 1 and 2. The air supply nasal tube 10 mainly has an air inlet tube η below the two nasal chambers 20, and one end of the air inlet tube is connected to a gas source tube. The air supply pipe 100 is connected to the air supply pipe 100 or directly closed, and the air inlet pipe 11 is provided with an air supply pipe 12 extending into the two nasal cavity 20, and the end of the air supply pipe 12 forms an open circular hole shape. The vent hole! 2〇, the diameter of the vent hole 12〇 is about the same as the inner diameter of the air supply tube 12, so that the air flow derived from the vent hole 120 of the sinuous circle is opposite to the inner membrane of the two nasal cavities, The air pressure is quite large. When the air is blown in for a long time, the pressure of the strong air pressure is concentrated on the inner membrane of the nasal cavity 20 relative to the air outlet 120, where the pressure is too concentrated and is extremely likely to cause unnecessary Injury, there is a need for improvement. [New content] In view of the above-mentioned use problems, the author of this case believes that it is necessary to design a gas supply structure for the nasal cannula of the 3 M430282 which can reduce the damage of the nasal endocardium of the patient when using the nasal cannula. The purpose of the present invention is to provide a gas supply nasal cannula structure, which is mainly characterized in that a venting hole of a gas supply pipe inserted into a nasal cavity of a patient is densely attached to a filling end of the gas supply pipe and an aperture of the gas permeable hole Very small, the pressure of the airflow can be minimized 'and the airflow can be effectively dispersed' so that the airflow introduced into the nasal cavity does not cause excessive concentration of the airflow pressure to reduce the airflow for the Damage to the nasal endometrium. Another object of the present invention is to provide an air supply nasal pipe outlet structure, wherein the air supply pipe is provided with a venting hole having a cylindrical structure, and the vent hole is interspersed with the cylindrical body. The end face and the peripheral wall are such that the derived airflow forms a scatter pattern. Another object of the present invention is to provide an air supply nasal pipe outlet structure, wherein the air supply pipe is provided with a vent hole, and the plug end is in the form of a cylindrical round plug end, and the vent hole is dispersed in the air vent hole. The end face of the plug is so that the derived airflow forms a scatter pattern. For the purpose of achieving the above objectives, the techniques, means and performances of the above-mentioned purposes are transferred to the preferred embodiment and described in detail in conjunction with the drawings. [Embodiment] First, please cooperate with Figure 4 in Figure 3. In view of the preferred embodiment of the air supply structure of the air supply nasal tube, the air supply nasal tube is inserted into the air tube 11'. The popularity (4) is respectively connected with one source tube and has a M430282 or can be directly closed at one end. In the embodiment of the present invention, the two ends of the air inlet pipe n are respectively connected to the air source pipe 100 to facilitate external connection of the required air source. The upper portion of the air inlet tube 11 is further provided with two upright air supply tubes 12, and the air supply tube 12 has a certain length, so that the insertion end 121 of the air supply tube 12 is enough to extend into the patient's nasal cavity 20, and the air supply tube 12 is The plugging end 121 is provided with a plurality of venting holes 122, and the venting hole 122 has a smaller aperture than the conventional one, that is, much smaller than the inner diameter of the air supply tube 12, so that the air supply tube 12 is inserted into the end surface 121 of the end 121. a small aperture vent 122, about 〇.imm to about 2 的 aperture 'and densely attached to the air supply tube 12 to the end 12 to make the airflow into the nasal cavity 2 into a dispersed airflow, and Each of the vent holes 122 may be in a shape parallel or non-parallel to each other, and the airflow may be effectively dispersed. As shown in Fig. 4, the insertion end 121 of the air supply tube 12 of the present invention surely protrudes into the nasal cavity 20 of the patient, and the small diameter vent hole 122 which is densely covered by the end portion 121 is inserted by the air supply tube 12 to make the introduced air flow. The airflow dispersed into a small number of strands does not mean to reduce the wind pressure of each small airflow and the impact force of the jets. Therefore, the inner membrane of the nasal cavity 20 at the position of the spray is dispersed into a large-area contact form. The pressure at the contact point is relatively small, and after the airflow is dispersed, the wind pressure is not excessively concentrated, that is, the possibility that the inner membrane of the nasal cavity 20 is damaged after contacting the small airflow can ensure that the nasal cavity 20 of the patient is intact, so as not to cause Unnecessarily infected wounds' to improve the comfort and safety of the patient's air supply nasal tube 10 using the present invention. The air supply pipe 12 of the present invention is provided with a plug-in end 121 of the vent hole 122, and a venting hole 122 is interspersed on the end surface of the plug end 121 of the cylindrical body and the peripheral wall for the purpose of exporting. The airflow forms a scatter form. The air supply tube 12 can also be a structure in which the insertion end 121 provided with the vent hole 122 is in the form of a plug end 121 having a cylindrical top end, and the vent hole 122 is interspersed on the end surface of the insertion end 121. In order to make the derived airflow form a scattered form. The above structure can achieve the above functions and purposes.
