Problems solved by technology

[0003] The existing nasal oxygen tubes are generally integrated, and it is difficult to adjust the oxygen flow rate. At the same time, the oxygen may contain dust. The filter cotton contained in the general nasal oxygen tube is used for a long time, and the dust may accumulate in the filter cotton, which is easy to reduce oxygen. The flow rate is inconsistent with the actual adjusted speed, which may cause blockage in serious cases and cause adverse effects on patients

Abstract

The invention relates to the field of medical equipment, in particular to a humidifying nasal oxygen cannula with an oxygen filtering function. The humidifying nasal oxygen cannula comprises an oxygen cannula body; a first external thread is formed in the tail end of the oxygen cannula body; a regulator is connected to the tail end of the oxygen cannula body; the tail end of the oxygen cannula body extends into the regulator; a connecting tube is arranged on the inner side of the regulator and is in sliding connection with the regulator; the connecting tube is rotationally connected with the tail end of the oxygen cannula body; a first internal thread is formed in the left end inside the connecting tube and matched with the first external thread; a sealing ring is arranged in the connecting tube and located on the right side of the first internal thread; and a second external thread is formed in the right side of the outer surface of the right side of the connecting tube. According to the nasal oxygen cannula, the oxygen delivery speed can be effectively controlled, dust contained in oxygen can be filtered out, meanwhile, a filter cotton net which is used for a long time and even contains too much dust can be replaced conveniently, so that the phenomena that the oxygen delivery speed is influenced and even blockage occurs are avoided, and a patient can inhale oxygen more conveniently.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a humidified nasal oxygen tube with 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, the nasal oxygen tube in the prior art generally includes an oxygen delivery tube, a nasal plug, a three-way connector, an adjustment buckle and a horn connector. [0003] The existing nasal oxygen tubes are generally integrated, and it is difficult to adjust the oxygen flow rate. At the same time, the oxygen may contain dust. The filter cotton contained in the general nasal oxygen tube is used for a long time, and the dust may accumulate in the filter cotton, which is easy to reduce oxygen. The flow rate does not conform to the actual adjusted speed, which may cause blockage in serious cases and cause adverse effect...
