Abstract

The invention discloses a nasal oxygen cannula with an oxygen filtering function. The nasal oxygen cannula comprises a nose plug bridge; two symmetrically-distributed nose plug heads are fixedly connected to the middle of one side of the nose plug bridge, guide pipes are fixedly connected to the two ends of the nose plug bridge, threaded pipes are fixedly connected to the ends, away from the noseplug bridge, of the guide pipes, three-way connectors are arranged at the ends of the threaded pipes, and filtering assemblies are arranged at the ends, away from the threaded pipes, of the three-wayconnectors. According to the nasal oxygen cannula with the oxygen filtering function, the detachable filtering assemblies are arranged on the three-way connectors; filter cotton in the filter assemblies plays a role in filtering oxygen; a partition plate and an elastic spoiler are arranged in the nasal plug bridge; the partition plate and the elastic spoiler play a role in turbulence and speed reduction, the flow speed of oxygen can be reduced, the elastic sealing head is arranged on the nose plug head and plays a role in sealing, external gas can be prevented from entering the nasal cavity from the nostrils of a patient, and meanwhile oxygen can be prevented from leaking from the nostrils.

Description

technical field [0001] The invention relates to a nasal oxygen tube, in particular to a nasal oxygen tube with an oxygen filtering function. Background technique [0002] Nasal oxygen tube is a kind of oxygen delivery tube for patients with dyspnea and hypoxia. It is a medical product used for oxygen delivery in clinical practice. At present, nasal oxygen tubes in the prior art generally include oxygen tubes, nasal plugs, three-way joints, adjustment buckles and horn joints. They are all integrated, and the flow rate of oxygen cannot be reduced, so that the oxygen flow rate is too fast to cause damage to the patient's nasal cavity or trachea, and the existing nasal oxygen tube does not have the function of filtering oxygen, so that impurities in the oxygen are easy to damage the patient's lungs. cause damage. Contents of the invention [0003] The purpose of the present invention is to provide a nasal oxygen cannula with oxygen filtering function, so as to solve the prob...
