Embodiment Construction
[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0014] The invention discloses a nasopharyngeal oxygen suction tube, such as figure 1 As shown, it includes a single nostril oxygen inhalation tube 3. One end of the single nostril oxygen inhalation tube 3 is inserted into the patient's nasopharynx through the nostril, and the other end is connected to the oxygen source through the connector 5. Generally, the connector 5 is inserted into the oxygen filter The air outlet of the water cup. The insertion end of the single nostril oxygen inhalation tube 3 and the position in contact with the nasopharynx all have a smooth transition, which reduces the stimulation of the oxygen inhalation tube to the nasopharynx and avoids causing local inflammation.
[0015] The single nostril oxygen suction tube 3 is provided with a fixing part 2 close to its insertion end, and the fixing part 2 is used to fix t...
