Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a novel nasal catheter. Background Art

[0002] A nasal cannula is a medical device used to deliver oxygen or medical gas to the patient's nasal cavity, usually for oxygen therapy or ventilator therapy. Nasal cannula is usually made of soft plastic and has two branches, one end is connected to the oxygen supplier, and the other end is inserted into the patient's nasal cavity. Compared with masks, nasal cannula is more comfortable and can deliver oxygen to the patient's respiratory tract more accurately. It is suitable for long-term oxygen therapy. This device is widely used in oxygen therapy, ventilator-assisted therapy, anesthesia process and other medical scenarios that require gas delivery. Nasal cannula is more comfortable than masks and can provide more accurate gas delivery.

[0003] However, currently available nasal cannulas may cause risks of skin abrasions, skin redness, swelling or ulcers during prolonged contact with the face and ears, and the nasal cannulas may slip when the patient moves or moves, requiring timely adjustment, or may cause the nasal cannulas to fall off, resulting in interruption of gas delivery and the need for reinstallation.

[0004] Therefore, in order to solve the above problems, a device is proposed that can protect the patient's ears and face when using it to prevent abrasions caused by long-term contact, and can adjust the position where the nasal catheter is pasted and fixed according to different patients, so that it can be applicable to a wider range of people.
