Description

Technical Field

[0001] This utility model relates to the field of head-mounted oxygen supply nasal mask technology, specifically a disposable head-mounted oxygen supply nasal mask. Background Technology

[0002] Currently, in painless gastroscopy, patients lie on their side under anesthesia and receive oxygen via a disposable nasal cannula. However, this cannula is prone to slipping out during the patient's drowsy state, requiring manual or adhesive tape fixation. Furthermore, the oxygen purity is not high, which may not meet the needs of patients requiring high oxygen concentrations, posing a potential danger. Traditional oxygen supply methods include disposable nasal cannulas and medical oxygen masks. While medical masks solve the problem of oxygen supply and prevent slippage, they also obstruct the mouth where the endoscope tube needs to be inserted. Therefore, there is an urgent need for a nasal mask that is easily fixed to the nose without obstructing the oral insertion procedure.

[0003] The prior art has the following defects or problems: The prior art disclosed in publication number CN221332275U is a head-mounted oxygen inhalation device, including an oxygen inhalation tube and an oxygen supply tube. Both ends of the oxygen inhalation tube are connected to one end of the oxygen supply tube, and the inner lumen of the oxygen inhalation tube and the inner lumen of the oxygen supply tube are connected. The oxygen inhalation tube is provided with a fixing component and a telescopic nasal cannula. The fixing component is used to fix the oxygen inhalation tube to the user's cheek. The telescopic nasal cannula includes a first nasal cannula and a second nasal cannula. One end of the first nasal cannula is disposed on the surface of the oxygen inhalation tube, and the inner lumen of the first nasal cannula is connected to the inner lumen of the oxygen inhalation tube. The surface of the second nasal cannula is threadedly connected to the inner lumen of the first nasal cannula, and the other end of the second nasal cannula extends to the outside of the first nasal cannula.

[0004] During use, the device can be rotated to change the length of the first nasal cannula extending to the outside of the second nasal cannula due to the threaded connection, thereby adapting to the needs of users with different nasal cavity spaces and depths.

[0005] The structure described above pertains to the oxygen supply tube stage and is not suitable for oxygen supply nasal masks. Although traditional medical oxygen masks on ventilators can provide closed-loop oxygen supply, they can easily obstruct oral surgery procedures and cannot fix the open mouth position of the human body. Therefore, a disposable headband-type oxygen supply nasal mask is proposed to address these shortcomings.

[0006] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0012] As a preferred technical solution of this utility model, both of the nasal mask bodies have air inlets inside, and both air inlets are connected to the bottom ends of the upward connecting pipe and the right side connecting pipe.

[0013] As a preferred technical solution of this utility model, the outer surfaces of the two exhaust ports are interlaced inside the nasal mask body. A pad may be provided on the outside of the exhaust ports. The pad is a non-essential item and is generally not provided. In special cases, it can be installed according to the patient's condition.

[0014] Compared with the prior art, this utility model provides a disposable headband-style oxygen supply nasal mask, which has the following beneficial effects:

[0015] 1. This disposable headband-style oxygen supply nasal mask, with a nasal mask body and an upward connection port, currently only covers the nose of the human body and provides oxygen to the nose through the upward connection port.
