Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a disposable oral and nasal airflow collection nasal oxygen tube. Background Art

[0002] Nasal oxygen cannula is a medical device used to deliver oxygen to the patient's nasal cavity. Its main function is to help correct the patient's hypoxemia and provide additional oxygen supply. Nasal oxygen cannula is usually made of soft plastic materials such as polyvinyl chloride and silicone rubber, with two small tubes inserted into the nostrils.

[0003] During use, the nasal oxygen cannula needs to be connected to the oxygen supply system, then inserted into the patient's nostrils about 1 cm and fixed securely. The operation steps include cleaning the nasal cavity, adjusting the oxygen flow, and recording the oxygen supply time and patient response.

[0004] The existing technology still has the following areas for improvement: the existing nasal oxygen cannula can usually only collect the exhaled airflow in the nasal cavity. If the oral airflow needs to be collected, it is necessary to wear an additional instrument, which is inconvenient; and after wearing the nasal oxygen cannula, the nasal oxygen cannula is easily blocked by secretions in the nasal cavity, such as snot, resulting in obstruction of oxygen delivery. Usually, after completing an oxygen inhalation, it needs to be manually cleaned; the traditional head ring fixation method will make the patient's head feel very tight and the skin marks are very obvious, which is quite uncomfortable.
