Description

Technical Field

[0001] The utility model relates to the field of medical supplies, in particular to an oxygen absorption tube. Background Art

[0002] Oxygen inhalation tubes are common medical supplies used to deliver pure oxygen or oxygen-containing gas to patients for treatment or breathing. The oxygen inhalation tube consists of a main tube, a ring tube, and two nasal plugs. The ring tube is connected to the main tube, and the nasal plugs are connected to the ring tube. When in use, the main tube is connected to the oxygen supply equipment, the ring tube is put on the head, the front part of the ring tube goes from the back of the head around the ears to the front of the head, and the nasal plugs are inserted into the nasal cavity of the oxygen inhaler.

[0003] The existing oxygen inhalation tube nasal plug is inserted into the nasal cavity of the oxygen inhaler, and the gas is ejected from the nasal plug directly into the nasal cavity. When the oxygen inhalation flow rate is large, the gas flow rate is fast, which has a significant impact on the nasal cavity, making the oxygen inhaler uncomfortable. In order to improve this situation, some patents have emerged.

[0004] Patent application number 201720769481.1 discloses a comfortable oxygen inhalation tube, which is specifically an improved nasal plug. The gas hole on the nasal plug is no longer a large hole, but a plurality of evenly distributed ventilation holes. The ventilation holes evenly arranged on the silicone nasal plug can disperse the gas flow, thereby effectively avoiding the discomfort caused to the nasal cavity by the impact of excessive airflow. Patent application number 202110419316.4 discloses an oxygen inhalation device, which specifically arranges a water-absorbing and breathable plug in the nasal plug. The water-absorbing and breathable plug is a porous structure component made of sponge, which can also disperse the gas flow and avoid the discomfort caused to the nasal cavity by the impact of excessive airflow.

[0005] However, the buffer structures of the above patents actually significantly reduce the flow area of ​​nasal congestion. Oxygen inhalation has requirements for the oxygen flow rate. If the flow area of ​​nasal congestion is reduced and the gas resistance is increased, the gas flow rate needs to be further increased to keep the flow rate unchanged, which is not conducive to reducing the impact; if the gas flow rate remains basically unchanged or even decreases, although there is a buffering effect, the oxygen flow rate will be reduced, affecting the treatment or health care effect. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an oxygen inhalation tube which has the effect of preventing the nasal cavity from being impacted by oxygen and has no obvious influence on the oxygen flow.

[0007] The technical solution adopted to solve the above problems is: the oxygen inhalation tube includes a main pipe, an annular pipe and two nasal plugs, the annular pipe is connected to the main pipe, and the nasal plug is connected to the annular pipe; the nasal plug includes a nasal plug tube and a gas baffle; the rear end of the nasal plug tube is connected to the annular pipe, the rear ends of the two nasal plug tubes are close and the front ends are separated to form a V-shaped structure, the gas baffle is arranged in the front-to-back direction, the gas baffle is connected to the front end of the nasal plug tube, and the gas output by the nasal plug tube is blown on the gas baffle.

[0008] Furthermore, the cross-sectional shape of the nasal obstruction tube is circular, the cross-sectional shape of the gas baffle is semicircular, and the gas baffle is connected to the outer half of the nasal obstruction tube.

[0009] Furthermore, the oxygen inhalation tube comprises a positioning transverse piece, which is arranged in front of the annular tube in the left-right direction, and is located between the two nasal congestion tubes and connected to the two nasal congestion tubes.

[0010] Furthermore, the included angle of the two nasal tubes is 45° to 90°.

[0011] Furthermore, the oxygen inhalation tube includes a tightening sleeve which is sleeved on the annular tube. The annular tubes on both sides of the tightening sleeve are an annular tube sleeve head and two sections of annular tube idle parts. The tightening sleeve can move along the annular tube to adjust the size of the annular tube sleeve head.

[0012] Furthermore, the oxygen inhalation tube includes a nasal congestion protection structure, which is connected to the annular tube and can block two nasal congestions.

[0013] Furthermore, the nasal congestion protection structure includes two protective structure halves, which include a sleeve ring, a flexible belt and a protective box half. The sleeve rings of the two protective structure halves are respectively sleeved on the idle parts of the two annular tubes, the flexible belt is connected to the sleeve ring, the protective box half is connected to the flexible belt, and the protective box half is provided with a semicircular tube groove; when the nasal congestion protection structure blocks two nasal congestions, the two protective box halves are respectively located on both sides of the annular tube and are buckled to form a protective box that blocks the two nasal congestions, and the annular tube passes through the tube groove.

[0014] The beneficial effect of the utility model is that the rear ends of the two nasal plug tubes of the utility model are close to each other and the front ends are separated to form a V-shaped structure, the gas baffle is arranged in the front-to-back direction, and the gas baffle is connected to the front end of the nasal plug tube. Figure 5 As shown, due to the flow guidance of the nasal congestion tube, the gas output by the nasal congestion tube blows on the gas baffle, and does not blow directly to the nasal cavity wall or the deep nasal cavity; after being refracted by the gas baffle, it continues to enter the deep nasal cavity. The gas baffle has a certain effect of slowing down the flow rate when refracting the gas, so the utility model has the beneficial effect of improving the comfort of oxygen inhalation. In addition, the utility model does not reduce the flow area of ​​nasal congestion, and has no obvious effect on the oxygen flow, which is conducive to ensuring the therapeutic or health care effect of oxygen inhalation.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figures 1 to 3 As shown, the oxygen inhalation tube includes a main tube 1, an annular tube 2 and two nasal plugs 3, the annular tube 2 is connected to the main tube 1, and the nasal plug 3 is connected to the annular tube 2; the nasal plug 3 includes a nasal plug tube 31 and a gas baffle 32; the rear end of the nasal plug tube 31 is connected to the annular tube 2, the rear ends of the two nasal plug tubes 31 are close and the front ends are separated to form a V-shaped structure, the gas baffle 32 is arranged in the front-to-back direction, the gas baffle 32 is connected to the front end of the nasal plug tube 31, and the gas output from the nasal plug tube 31 is blown on the gas baffle 32.

[0025] The utility model is used as follows Figure 4 As shown, the main pipe 1 is connected to the oxygen supply equipment, the annular pipe 2 is put on the head, the front part of the annular pipe 2 goes from the back of the head around the ear to the front of the head, and the nasal plug 3 is inserted into the nasal cavity of the oxygen inhaler.

[0026] In the present invention, the rear ends of the two nasal plug tubes 31 are close to each other and the front ends are separated to form a V-shaped structure. The gas baffle 32 is arranged in the front-to-back direction and the gas baffle 32 is connected to the front end of the nasal plug tube 31. When in use, Figure 5 As shown, due to the flow guidance of the nasal congestion tube 31, the gas outputted from the nasal congestion tube 31 blows on the gas baffle 32, and does not blow directly to the nasal cavity wall or the deep part of the nasal cavity; after being refracted by the gas baffle 32, it continues to enter the deep part of the nasal cavity. The gas baffle has a certain effect of slowing down the flow rate when refracting the gas, so the utility model has the beneficial effect of improving the comfort of oxygen inhalation. In addition, the utility model does not reduce the flow area of ​​the nasal congestion, and has no obvious effect on the oxygen flow rate, which is conducive to ensuring the therapeutic or health care effect of oxygen inhalation.

[0027] The specific configuration of the nasal plug tube 31 and the gas baffle 32 is as follows: Figure 2 and Figure 3 As shown, the cross-sectional shape of the nasal tube 31 is circular, the cross-sectional shape of the gas baffle 32 is semicircular, and the gas baffle 32 is connected to the outer half of the nasal tube 31. The angle between the two nasal tubes 31 is preferably 45° to 90°. If the angle is too small, the gas baffle 32 needs to be very long to block the oxygen, which is not suitable; if the angle is too large, it is not conducive to the forward flow of oxygen, which is also not suitable.

[0028] Furthermore, the oxygen inhalation tube of the utility model preferably includes a positioning transverse piece 6, which is arranged in the left-right direction in front of the annular tube 2, and is located between the two nasal plug tubes 31 and connected to both nasal plug tubes 31. The positioning transverse piece 6 can keep the angle between the two nasal plug tubes 31 unchanged, and can abut against the nasal septum to prevent the nasal plug 3 from extending too deeply into the nasal cavity.

[0029] Similar to the prior art, the oxygen inhalation tube includes a tightening sleeve 4, which is sleeved on the annular tube 2. The annular tubes 2 on both sides of the tightening sleeve 4 are respectively an annular tube sleeve head 21 and two sections of annular tube idle parts 22. The tightening sleeve 4 can move along the annular tube 2 to adjust the size of the annular tube sleeve head 21.

[0030] like Figure 4 As shown, when the utility model is used, the tightening sleeve 4 is moved close to the chin of the oxygen inhaler, so that the annular tube sleeve head 21 can be tightly covered on the head of the oxygen inhaler to avoid loosening, thereby preventing the nasal obstruction 3 from falling out of the nasal cavity.

[0031] For patients who need long-term oxygen inhalation in hospital, the oxygen tube needs to be stored when not in use. In order to prevent the nasal congestion from being contaminated during storage, the utility model preferably includes a nasal congestion protection structure 5, which is connected to the annular tube 2 and can cover the two nasal congestion 3.

[0032] The specific structure of the nasal congestion protection structure 5 can be as follows Figure 1 , Figure 6 and Figure 7 As shown, the nasal congestion protection structure 5 includes two protection structure halves 51, and the protection structure halves 51 include a sleeve ring 513, a flexible belt 512 and a protection box half 511. The sleeve rings 513 of the two protection structure halves 51 are respectively sleeved on the idle parts 22 of the two annular tubes, the flexible belt 512 is connected to the sleeve ring 513, and the protection box half 511 is connected to the flexible belt 512. The protection box half 511 is provided with a semicircular tube groove 514; when the nasal congestion protection structure 5 blocks two nasal congestion 3, the two protection box halves 511 are respectively located on both sides of the annular tube 2 and are buckled to form a protection box that blocks the two nasal congestion 3, and the annular tube 2 passes through the tube groove 514.

[0033] When the oxygen tube is used, the nasal congestion protection structure 5 is not used. Figure 1As shown, since the nasal plug protection structure 5 is connected to the idle part 22 of the annular tube, it is far away from the head of the oxygen inhaler and does not touch the head of the oxygen inhaler. When the oxygen inhalation tube is not in use, it is stored. When storing, the tightening sleeve 4 and the sleeve ring 513 are moved close to the nasal plug; then the two protection box halves 511 are placed on both sides of the annular tube 2 and the nasal plug 3 respectively, and then the two protection box halves 511 are buckled together to form a protection box that covers the two nasal plugs 3, so as to prevent the nasal plugs 3 from being contaminated.
