Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to an oxygen inhalation nasal catheter. Background Art

[0002] Bronchoscopy plays an important role in diagnosing lung diseases such as pneumonia, pulmonary hemorrhage and lung tumors. However, during bronchoscopy, hypoxemia is the most common complication. Once it occurs, it may lead to interruption of the operation, aggravate the patient's condition, and even endanger life.

[0003] At present, the common method of treating hypoxemia is to withdraw the bronchoscope into the main bronchus and strengthen oxygen inhalation at the same time. This usually includes changing the oxygen inhalation from one nasal cannula to two nasal cannula, or connecting the oxygen inhalation nasal cannula to the bronchoscope inlet to increase the oxygen flow. However, connecting the oxygen inhalation nasal cannula to the bronchoscope inlet is extremely difficult to operate with the current oxygen inhalation nasal cannula. For this reason, we propose an oxygen inhalation nasal cannula. Utility Model Content
