Description

Technical Field

[0001] This utility model relates to the field of oxygen supply equipment technology, and in particular to a dual-channel nasal oxygen tube connector and its nasal oxygen tube. Background Technology

[0002] In the medical and healthcare fields, gas therapy, as a non-invasive treatment, is widely used as an adjunct therapy for various diseases and in daily health maintenance. Among these, oxygen and hydrogen inhalation, as two important gas therapy methods, have attracted considerable attention due to their unique physiological effects. Currently, most commercially available oxygen and hydrogen inhalation devices deliver gas to the patient through masks or nasal cannulas. While masks can cover a large area, they are inconvenient to wear and can easily cause patients to feel stuffy; traditional nasal cannulas often only deliver oxygen or hydrogen at a time, failing to meet the need for simultaneous oxygen and hydrogen inhalation.

[0003] While existing dual-channel nasal oxygen cannulas have solved the problem of oxygen and hydrogen inhalation, their structure makes them difficult to manufacture and costly. Therefore, it is necessary to design a dual-channel nasal oxygen cannulas that can solve the problem of oxygen and hydrogen inhalation while also taking cost into consideration. Utility Model Content

[0004] This invention provides a dual-channel nasal oxygen cannula connector and its nasal oxygen cannula to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A dual-channel nasal oxygen tube connector includes: a branch tube installation interface tube, a connector branch flow channel tube, air passage I, and air passage II;

[0007] The branch tube installation interface tube is used to connect the branch tube to the nasal oxygen tube;

[0008] The connector branch pipe connects to the branch pipe and the interface pipe. After the two connector branch pipes are joined together, they match the internal shape of the air inlet pipe of the nasal oxygen cannula.

[0009] Air passage I and air passage II are respectively connected to the connector branch passage tubes, and air passage I and air passage II are respectively connected to the two air outlet tubes of the nasal oxygen cannula's nasal inhaler.

[0011] Preferably, the connector branch flow pipe has a buckle and a buckle groove on its flat surface. When the connector branch flow pipes of two connectors overlap, the buckle of one connector branch flow pipe is engaged with the buckle groove of the other connector branch flow pipe.

[0012] Preferably, the snap fastener includes an arc-shaped surface and an inclined surface perpendicular to the plane of the connector branch flow channel pipe. The arc-shaped surface is disposed facing the branch pipe installation interface pipe, and the inclined surface is disposed away from the branch pipe installation interface pipe. The distance between the inclined surface and the plane of the connector branch flow channel pipe gradually decreases to zero in the direction away from the branch pipe installation interface pipe.

[0013] Preferably, both gas passage I and gas passage II are tubular structures that intersect with the connector branch passage pipe, and the cross-sections of both gas passage I and gas passage II are semi-circular. The planes of both gas passage I and gas passage II are flush with the plane of the connector branch passage pipe, and the end planes of both gas passage I and gas passage II are perpendicular to the plane of the connector branch passage pipe.

[0014] Preferably, when the connector branch passages of the two connectors are overlapped, the shape of the overlapped air passage I of one connector and air passage II of the other connector matches the internal shape of the air outlet tube of the nasal oxygen cannula.

[0015] Preferably, a positioning transition pipe is provided between the connector branch flow path pipe and the branch pipe installation interface pipe for transition. The positioning transition pipe is round and its outer diameter is equal to the diameter of the connector branch flow path pipe.

[0018] Preferably, a diversion baffle is fixed inside the air outlet tube of the nasal inhaler. The diversion baffle is arranged radially along the air outlet tube, and the end of the diversion baffle facing the air inlet tube abuts against the overlapping position of the corresponding air passage I and air passage II.

[0019] Beneficial effects:

[0020] First, the dual-channel nasal oxygen tube connector disclosed in this application achieves dual-channel gas delivery by connecting the two connectors of the branch flow channels together and matching the internal shape of the air inlet tube of the nasal oxygen tube.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Example 1

[0035] A dual-channel nasal oxygen cannula connector, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes: a branch pipe installation interface pipe 11, a connector branch passage pipe 12, an air passage I 13, and an air passage II 14; the branch pipe installation interface pipe 11 is used to insert the branch pipe 3 of the nasal oxygen tube; the connector branch passage pipe 12 is connected to the branch pipe installation interface pipe 11, and the connector branch passage pipes 12 of the two connectors are overlapped together to match the internal shape of the air inlet pipe 21 of the nasal suction head 2 of the nasal oxygen tube; the air passage I 13 and the air passage II 14 are respectively connected to the connector branch passage pipe 12, and the air passage I 13 and the air passage II 14 are respectively connected to the two air outlet pipes 22 of the nasal suction head 2 of the nasal oxygen tube.

[0036] By overlapping the connector branch passages 12 of the two connectors together and matching their internal shape with the air inlet tube 21 of the nasal oxygen cannula's nasal suction head 2, a dual-channel gas delivery system is achieved. Since all related structures of the connector are exposed externally, and its interior is a smooth channel, the original structure avoids the need for a partition inside the air inlet tube 21 to separate the two passages. This simplifies the mold manufacturing of this connector, facilitates demolding, increases the yield rate, and ultimately reduces production costs.

[0037] Preferably, the cross-section of the connector branch flow channel 12 is semi-circular, and the cross-section of the connector branch flow channel 12 after the two connectors are overlapped is circular. Using a semi-circular cross-section can save materials and help reduce sharp corner structures, thereby ensuring its strength and simplifying mold design.

[0038] Preferably, combined with Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the connector branch flow channel 12 has a snap fastener 15 and a snap fastener groove 16 on its flat surface. When the connector branch flow channel 12s of two connectors overlap, the snap fastener 15 of one connector branch flow channel 12 snaps into the snap fastener groove 16 of the other connector branch flow channel 12. The snap fastener 15 and the snap fastener groove 16 ensure that the connector branch flow channel 12s of the two connectors are reliably overlapped.

[0039] Specifically, the connector branch conduit 12 has a curved shape to fit the face.

[0040] Preferably, the snap fastener 15 includes an arcuate surface 151 and an inclined surface 152 perpendicular to the plane of the connector branch passage pipe 12. The arcuate surface 151 faces the branch pipe mounting interface pipe 11, and the inclined surface 152 faces away from the branch pipe mounting interface pipe 11. The distance between the inclined surface 152 and the plane of the connector branch passage pipe 12 gradually decreases to zero in the direction away from the branch pipe mounting interface pipe 11. After the snap fastener 15 is engaged with the snap fastener groove 16, the arcuate surface 151 abuts against the side wall of the snap fastener groove 16, which can restrict the relative movement of the connector branch passage pipes 12 of the two connectors in the direction away from the branch pipe mounting interface pipe 11. The inclined surface 152 is used to guide the connector branch passage pipes 12 of the two connectors when they overlap.

[0041] Specifically, the buckle 15 is located between the buckle groove 16 and the branch pipe installation interface pipe 11. The buckle 15 protrudes from the plane of the connector branch flow path pipe 12. The buckle groove 16 passes through the plane of the connector branch flow path pipe 12. When the buckle 15 is engaged in the buckle groove 16, the buckle 15 blocks the buckle groove 16, and the planes of the two connector branch flow path pipes 12 abut against each other, ensuring the isolation of the two connector branch flow path pipes 12.

[0042] Preferably, combined with Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, both air passage I 13 and air passage II 14 are tubular structures that intersect with the connector branch passage 12, and the cross-sections of both air passage I 13 and air passage II 14 are semi-circular. The planes of air passage I 13 and air passage II 14 are flush with the plane of the connector branch passage 12, and the end planes of air passage I 13 and air passage II 14 are perpendicular to the plane of the connector branch passage 12. The structure of air passage I 13 and air passage II 14 provides initial guidance from the connector branch passage 12, and the air passages I 13 and air passage II 14 do not protrude excessively from the connector branch passage 12, facilitating the insertion of the inlet tube 21 of the nasal suction head 2.

[0043] Preferably, when the connector branch passages 12 of the two connectors are connected together, the shape of the air passage I 13 of one connector and the air passage II 14 of the other connector after being connected matches the internal shape of the air outlet tube 22 of the nasal oxygen cannula, thereby achieving the positioning and docking of the air outlet tube 22 of the nasal oxygen cannula, ensuring that the gas flowing out from the corresponding air passage I 13 and air passage II 14 flows into the same air outlet tube 22, and then flows into the user's nasal cavity through the guide of the air outlet tube 22.

[0044] Preferably, a positioning transition pipe 17 is provided between the connector branch flow path pipe 12 and the branch pipe installation interface pipe 11 for transition. The positioning transition pipe 17 is cylindrical and its outer diameter is equal to the diameter of the connector branch flow path pipe 12. The end face of the positioning transition pipe 17 facing the connector branch flow path pipe 12 can position the end of the connector branch flow path pipe 12 of the other connector, and the air intake pipe 21 can continue to extend to the positioning transition pipe 17, improving the reliability of the overlap of the connector branch flow path pipes 12 of the two connectors.

[0045] Preferably, the branch pipe mounting interface tube 11 is a round tube with an outer diameter larger than the air inlet tube 21 of the nasal oxygen cannula 2, and the end face of the branch pipe mounting interface tube 11 facing the positioning transition tube 17 can be used for positioning the end face of the air inlet tube 21 of the nasal oxygen cannula 2.

[0046] Specifically, the branch pipe installation interface pipe 11, the connector branch flow path pipe 12, the air passage I 13 and the air passage II 14, the buckle 15, the buckle groove 16 and the positioning transition pipe 17 are integrally formed by injection molding.

[0047] Example 2

[0048] A nasal oxygen cannula comprising a dual-channel nasal oxygen cannula connector, combined with Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, it includes: two dual-channel nasal oxygen tube connectors, a nasal suction head 2, a branch tube 3, an adjustment ring 4, a main tube 5, and a flared mouth 6. The two dual-channel nasal oxygen tube connectors are inserted from both ends of the air inlet tube 21 of the nasal suction head 2. The air inlet tube 21 wraps around the connector branch passage tube 12 of the two connectors that are connected together, thus realizing dual-channel air supply of the nasal oxygen tube.

[0049] Specifically, the nasal inhaler 2 is made of silicone. The elasticity of the silicone allows the air inlet tube 21 to tightly wrap around the connector branch passage tube 12 of the two connectors, thereby improving wearing comfort.

[0050] Specifically, a nose strip 23 is also fixed on the air inlet tube 21 of the nasal suction head 2. When the nasal suction head 2 is inserted into the user's nasal cavity, the nose strip 23 can fit against the tip of the nose to fix the nasal suction head 2 and prevent it from falling off.

[0051] Preferably, a flow divider 221 is fixedly provided inside the air outlet tube 22 of the nasal inhaler 2. The flow divider 221 is arranged radially along the air outlet tube 22, and one end of the flow divider 221 facing the air inlet tube 21 abuts against the overlapping position of the corresponding air passage I 13 and air passage II 14. The flow divider 221 separates the airflow flowing out from the corresponding air passage I 13 and air passage II 14 to avoid airflow interference due to the close proximity of air passage I 13 and air passage II 14.

[0052] Specifically, the air intake pipe 21, the air outlet pipe 22, the nose strip 23, and the diverter baffle 221 are integrally formed by injection molding.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
