Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an ear-hanging oxygen-inhalation auxiliary device. Background Art

[0002] In the existing oxygen therapy, an ear-hanging oxygen tube as described in the Chinese patent application with the publication number CN216319331U is usually provided. When in use, the nasal tube on the oxygen tube needs to be inserted into the patient's nostrils for oxygen inhalation, and the middle section of the oxygen tube is worn on the ear through the ear-hanging part, so that the oxygen tube on the ear-hanging part pulls the nasal tube upwards, so that the nasal tube is not easy to fall off from the nostrils.

[0003] However, the existing ear-hook oxygen inhalation tube has a poor fit with the ear during use, and is easily flipped back and forth, causing the ear hook to fall off, which is inconvenient for patients to move. At the same time, the existing ear hook exerts force on the ear from top to bottom, which can easily cause soreness on the top of the ear after wearing for a long time. Utility Model Content

[0004] The utility model aims to provide an ear-hanging oxygen inhalation auxiliary device, which can be hung on the ear stably and can avoid the ear-hanging part from causing pain to the top of the back of the ear.

[0005] In order to solve the above technical problems, the utility model adopts the following solutions:

[0006] An ear-hanging oxygen inhalation auxiliary device comprises an ear-hanging part and a nasal suction tube, wherein the ear-hanging part comprises a fitting section for fitting against the back of the ear, the fitting section comprises a hook section extending from the back of the ear along the upper side of the ear to the front side of the ear and a connecting section extending from the back of the ear along the lower side of the ear, an ear hook piece for hooking the auricle is arranged at one end of the hook section away from the connecting section, and a sleeve section connected to the outer side of the oxygen inhalation tube is arranged at one end of the connecting section away from the hook section. The function of the ear hook piece is to hook the ear-hanging part from the front side of the auricle through the arrangement of the ear hook piece and the spatial relationship between the ear hook piece and the fitting section and the connecting section, so that the ear-hanging part can be firmly hooked on the ear and is not easy to fall off.

[0007] Furthermore, a reinforcement section is provided between the hook section and the connection section, and the outer diameter of the reinforcement section is larger than that of the hook section. Its function is that, through the provision of the reinforcement section, the reinforcement section can fit the back of the ear, so that the force bearing point between the ear hook and the ear is transferred from the hook section to the ear hook and the reinforcement section, thereby preventing the ear hook from pressing the top of the back of the patient's ear after the patient wears the ear hook for a long time.

[0008] Furthermore, the hook section, the reinforcement section and the connecting section are all solid structures made of the same material, so that the gravity of the reinforcement section is greater than that of the hook section and the connecting section, thereby enhancing the structural strength of the reinforcement section.

[0009] Furthermore, the outer diameter of the connecting section is smaller than the outer diameter of the reinforcing section. Its function is to make the center of gravity of the entire ear hook part be located on the reinforcing section rather than the middle of the hook section through the design of the size relationship between the connecting section and the reinforcing section, thereby avoiding the hook section from directly pressing on the top of the back of the ear.

[0010] Furthermore, the hook section is in an inverted U shape, and the reinforcement section and the connection section are both in a bad arc shape.

[0011] Furthermore, the hook ear piece is cylindrical, and the extension direction of the connecting section between the hook section and the hook ear piece is perpendicular to the extension direction of the hook ear piece. A weight-reducing hole is provided in the hook ear piece and is arranged in the extension direction of the hook ear piece. Its function is that the hook ear piece can be easily hooked in the ear through the arrangement of the extension direction of the hook ear piece.

[0012] Furthermore, the sleeve section is in the shape of a hollow circular tube, and a diameter expansion groove extending along the extension direction of the sleeve section is provided on the side wall of the sleeve section. The function of the diameter expansion groove is to facilitate the oxygen absorption tube to open the sleeve section outwards, avoid the sleeve section squeezing the oxygen absorption tube, and facilitate the oxygen absorption tube to move in the sleeve section.

[0013] Furthermore, the sleeve section includes a straight section near the nasal suction tube and an arc section away from the nasal suction tube. The straight section facilitates the oxygen inhalation tube to extend horizontally through the straight section to the nasal suction tube below the nostril; the arc section facilitates the oxygen inhalation tube to extend from the oxygen inhalation device to the ear hook.

[0014] Furthermore, the nasal suction tube includes two nasal inlet tubes for extending into the nostrils and a connecting tube connecting the two nasal inlet tubes, and the section of the nasal inlet tube away from the connecting tube is prism-shaped. Its function is that the nasal inlet tube can open the nostrils through the setting of the shape of the nasal inlet tube, and the nasal inlet tube is clamped by the elastic force of the nostrils.

[0015] Furthermore, the cross-sectional area of ​​the nasal inlet tube away from the connecting tube section is larger than the cross-sectional area of ​​the nasal inlet tube section near the connecting tube section, and the cross-sectional area of ​​the connecting tube section away from the nasal inlet tube section is larger than the cross-sectional area of ​​the nasal inlet tube section. The effect is that, through the change in the cross-sectional area of ​​the nasal inlet tube and the connecting tube, the oxygen in the oxygen inhalation tube can quickly enter the connecting tube and diffuse into the nostrils as quickly as possible.

[0016] The utility model has the beneficial effects:

[0017] 1. Through the arrangement of the ear hook and the spatial relationship between the ear hook, the fitting section and the connecting section, the ear hook can be hooked from the front side of the auricle, so that the ear hook can be firmly hooked on the ear and is not easy to fall off;

[0018] 2. By setting the reinforcement section, the reinforcement section can fit the back of the ear, so that the force point between the ear hook and the ear is transferred from the hook section to the ear hook and the reinforcement section, avoiding the ear hook from pressing the top of the back of the patient's ear after the patient wears the ear hook for a long time.
