Description

Technical Field

[0001] This utility model relates to the field of oxygen nasal cannula technology, specifically a high-flow oxygen nasal cannula. Background Technology

[0002] Oxygen nasal cannulas, often simply called nasal cannulas, are medical devices primarily used to deliver additional oxygen to a patient's nasal cavity to correct hypoxia symptoms, maintain normal blood oxygen partial pressure and blood oxygen saturation, and promote the body's metabolism.

[0003] A medical high-flow oxygen nasal cannula, disclosed in authorized patent application CN206063515U, includes a nasal cannula body, a nasal cannula disposed on the nasal cannula body, an air bag disposed on the nasal cannula body, a fixing sleeve disposed on the nasal cannula body, and a nasal cannula fixing part disposed on the nasal cannula body. Both ends of the nasal cannula are fixed to the nasal cannula fixing part, which is hollow inside. The air bag is fixed to the lower middle part of the nasal cannula, and the air bag has two oxygen inhalation heads. The nasal cannula has two symmetrical inflation ports. The fixing sleeve is fitted onto the nasal cannula fixing part, and the fixing sleeve has a connector for connecting to an external oxygen supply device. Its structure is simple, easy to use and install, simple to operate, provides good oxygen supply, is easy to connect, and securely fixes to the ear, increasing the tightness of the connection with the patient and the comfort of oxygen supply. It is low in cost, has a wide range of applications, a long service life, and is safe and reliable.

[0004] As shown in the prior art, when using the high-flow oxygen nasal cannula, the patient needs to hang the nasal cannula behind the ear. However, since the nasal cannula is made of soft material, it cannot completely fit the patient's ear and is very easy to loosen when the patient moves their head, requiring the patient to make frequent adjustments, which causes discomfort.

[0005] Therefore, it is necessary to provide a high-flow oxygen nasal cannula to solve the above-mentioned technical problems. Utility Model Content

[0018] 1. This application, by installing a leak-proof structure on the outer wall of the nasal cannula, can effectively prevent excessive oxygen leakage when it reaches the end of the nasal cannula, thereby improving oxygen utilization efficiency and ensuring that the patient can receive a sufficient oxygen supply.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides two technical solutions:

[0026] Figures 1 to 3 The first embodiment is shown: a high-flow oxygen inhalation nasal cannula, including a connecting tube 1, with catheter bodies 2 symmetrically connected to both ends of the connecting tube 1, a parallel block 3 slidably connected below the two catheter bodies 2, and a nasal suction tube 4 symmetrically fixed to one side of the connecting tube 1 for insertion into the nasal cavity.

[0027] The outer wall of the nasal cannula 4 is equipped with a leak-proof structure to prevent excessive oxygen leakage. The connecting tube 1 is equipped with an anti-slip component to reduce the slippage of the connecting tube 1. The outer walls of the catheter bodies 2 on both sides of the connecting tube 1 are equipped with ear hook components to make the catheter bodies 2 fit the patient's ears.

[0028] The leak-proof structure includes a conical plug 5 that is slidably connected to the outer wall of the nasal cannula 4. A movable sleeve 6 is fixed to one end of the conical plug 5 near the connecting tube 1. An anti-slip groove is formed on the outer wall of the movable sleeve 6.

[0029] This application, by installing a leak-proof structure on the outer wall of the nasal cannula 4, can effectively prevent excessive oxygen leakage when it reaches the end of the nasal cannula 4, thereby improving oxygen utilization efficiency and ensuring that the patient can receive a sufficient oxygen supply.

[0030] Figures 2 to 3 The second embodiment is shown, and its main difference from the first embodiment is:

[0031] The anti-slip component includes an installation tube 7 fixed in the middle of the connecting tube 1, a polygonal sleeve 8 rotatably connected to the outer wall of the installation tube 7, and a number of first anti-slip pads 9 fixed at equal intervals on the outer wall of the polygonal sleeve 8.

[0032] The ear loop assembly includes several elastic cords 10 that are hung on the outer wall of the catheter body 2. The catheter body 2 is slidably connected to the inner wall of the elastic cords 10. A C-shaped ear loop 11 is fixed below the several elastic cords 10. A second anti-slip pad 12 is fixed on the inner wall of the C-shaped ear loop 11.

[0033] The application, through the design of anti-slip components, can reduce the slippage of the connecting tube 1 during use, ensuring that the nasal cannula is firmly fixed to the patient and avoiding unstable oxygen supply due to slippage; the introduction of the ear hook component allows the cannula body 2 to fit the patient's ear, effectively dispersing the pressure of the nasal cannula on the patient's face and improving wearing comfort.

[0034] Working principle:

[0035] The high-flow oxygen nasal cannula is connected to an oxygen source. Oxygen is delivered to the connecting tube 1 by the cannula bodies 2 on both sides, and then the oxygen enters the patient's nasal cavity through the nasal cannula 4. Pushing the movable sleeve 6 causes the conical plug 5 to slide on the outer wall of the nasal cannula 4. The anti-slip groove on the outer wall of the movable sleeve 6 makes it easier to push the movable sleeve 6, so that the conical plug 5 can slide and adjust its position as needed to fit tightly to the patient's nostrils and prevent excessive oxygen leakage.

[0036] The outer wall of the mounting tube 7 in the middle of the connecting tube 1 is rotatably connected to a polygonal sleeve 8. Compared with the traditional cylindrical connecting tube 1 which directly contacts the skin, the design of the polygonal sleeve 8 can effectively increase the stability of the connecting tube 1. Moreover, the polygonal design of the polygonal sleeve 8 can adapt to various facial structures and fit fully with the patient's face, making the use of the nasal cannula more stable. Several first anti-slip pads 9 are fixed at equal intervals on the outer wall of the polygonal sleeve 8. These anti-slip pads can further enhance the anti-slip effect and ensure that the nasal cannula is firmly fixed on the patient.

[0037] The C-shaped ear loop 11 and the second anti-slip pad 12 ensure that the nasal cannula fits the patient's ear and improves the stability of wearing it; the elastic cord 10 is designed so that the patient can adjust the position of the C-shaped ear loop 11 on the outer wall of the cannula body 2 as needed.
