Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, in particular to a nasal plug-type catheter that can effectively fit the nasal cavity. Background Art

[0002] High-flow nasal oxygen cannula plays an important role in gas transmission during high-flow nasal oxygen therapy. It can directly deliver a certain oxygen concentration of air-oxygen mixed with high-flow warm and humidified gas to the patient through a sealed nasal oxygen cannula.

[0003] For standard nasal oxygen cannulas, when the oxygen flow rate exceeds 6L / min, the dry, cold, high-flow gas delivered through the outlet can easily dry out the nasal mucosa, even causing bleeding, pain in the frontal sinuses, and discomfort. Furthermore, most users use nasal oxygen cannulas at night, which can easily cause them to fall off if they roll over or make other movements. The darkness at night makes it difficult to locate a fallen cannula, thus compromising oxygen delivery. Furthermore, because noses vary in size, existing cannulas often have a poor fit and are prone to slipping off.

[0004] In order to overcome the defects in the prior art, the utility model designs a nasal plug type catheter with high fit. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a nasal obstruction catheter which increases patient comfort and is not easy to fall off and has high fit.

[0006] To solve the above-mentioned existing technical problems, the present invention adopts the following solution: a nasal plug-type catheter with high fit, comprising a nasal catheter, the nasal catheter being a one-piece molded structure, a fixing belt being installed on the inner side of the nasal catheter, a trachea being provided on the nasal catheter, and connection holes being provided on both sides of the nasal catheter, wherein an end cap is installed in the connection hole on the left side, and the connection hole on the right side is connected to a card joint.

[0007] Preferably, the air pipe is set at an inward inclination angle of 25° to 35°.

[0008] Preferably, the fixing belt is forked with connectors at both ends, each connector is equipped with a snap-fit ​​block, the snap-fit ​​block is connected to the buckle, and the buckle is respectively installed on the upper elastic band and the lower elastic band.

[0009] Preferably, the clamping joint is connected to the rotary joint via a sliding tube, a buckle is sleeved on the sliding tube, and a neck strap is inserted and installed on the buckle.

[0010] Preferably, a hanging ring is sleeved on the sliding tube.

[0011] The present invention adopts the above technical solution to provide a nasal plug-type catheter with high fit, which has the following advantages compared with the existing technology:

[0012] 1. The nasal catheter is formed in one step after pressing and closing the mold, and can withstand large axial static tension.

[0013] 2. The trachea adopts a curvature and inward inclination design to effectively prevent high-speed airflow from directly impacting the patient's forehead and causing discomfort to the patient, thereby improving the patient's comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a schematic diagram of the structure of the utility model.

[0015] Figure 2 It is a partial schematic diagram of the nasal catheter of the present invention.

[0016] In the figure, nasal catheter 1, fixing belt 2, trachea 3, connecting hole 4, end cover 5, clamping joint 6, connecting head 7, clamping block 8, buckle 9, upper elastic band 10, lower elastic band 11, sliding tube 12, rotating joint 13, buckle 14, neck strap 15, and hanging ring 16. DETAILED DESCRIPTION

[0017] like Figure 1 、 2 As shown, a nasal plug-type catheter with high fit includes a nasal catheter 1, a fixing belt 2 is integrally adhered to the inner side of the nasal catheter 1, an trachea 3 is provided on the nasal catheter 1, and connecting holes 4 are respectively provided on both sides of the nasal catheter 1, wherein the connecting hole 4 on the left is installed with an end cap 5, and the connecting hole 4 on the right is connected to a clamping joint 6, the trachea 3 is set at an angle of 25° to 35°, and the fixing belt 2 has forked connectors 7 at both ends, each connector 7 is installed with a clamping block 8, the clamping block 8 is connected to a buckle 9, and the buckle 9 is respectively installed on the upper elastic band 10 and the lower elastic band 11, the clamping joint 6 is connected to the rotary joint 13 through a sliding tube 12, the sliding tube 12 is sleeved with a buckle 14, a neck strap 15 is inserted and installed on the buckle 14, and the sliding tube 12 is sleeved with a hanging ring 16.

[0018] During actual operation, the rotary joint 13 is connected to the machine end, and the gas enters the slide tube 12 from the rotary joint 13. The slide tube 12 is connected to the nasal catheter 1. The other end of the nasal catheter 1 is equipped with an end cap 5, which plays a role of a single seal. After passing through the nasal catheter 1, the gas will flow through the trachea 3 to the patient's nasal cavity. The trachea 3 is made of soft material and has its own curvature, which can effectively prevent the high-speed airflow from directly impacting the patient's frontal sinus and causing discomfort to the patient, thereby improving the patient's comfort. A fixing belt 2 is integrally provided on the inner side of the nasal catheter 1 to fix it. The belt 2 is connected to the upper elastic band 10 and the lower elastic band 11 through the buckle 9.
