Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an anti-blocking and anti-irritation oxygen inhalation tube cover. Background Art

[0002] In clinical treatment and nursing, oxygen tubes are often used to provide oxygen to patients. At present, clinical medicine mostly uses a nasal tube connected to the oxygen tube, which is inserted into the patient's nasal cavity to supply oxygen to the patient. The oxygen nasal tubes used are mostly straight tubes with a straight front end. They pass directly through the patient's nasal lining, which can easily cause irritation to the nasal lining and cause severe discomfort. In addition, excessive gas flow rate will affect the patient's breathing efficiency. In addition, it is difficult to deal with the impact of the patient's nasal secretions on the ventilation of the pipeline, and it is not convenient to discharge the liquid discharged from the patient's nasal cavity into the oxygen tube in time. The secretions in the exhaust gas accumulate in the oxygen tube and are easily inhaled into the lungs by the patient, choking the patient.

The bottom end of the seat column is fixedly mounted on the adjusting plate, and the bottom end of the screw is fixedly mounted on the mounting plate, thereby constituting the telescopic rod after installation; the bottom end of the seat column can also be fixedly mounted on the mounting plate, and the bottom end of the screw is fixedly mounted on the adjusting plate; when in use, only the screw barrel needs to be rotated to extend and retract the screw and the seat column, thereby adjusting the distance between the adjusting plate and the mounting plate.

[0015] When using, first align the left and right tubes of the nasal tube with the two nostrils, with the outer end of the nasal tube as close to the nostrils as possible. You can also touch the nostrils but do not insert the nostrils. Try to put the mask on the face, mouth and nose, adjust the position of the mask, or rotate the telescopic rod to adjust the position of the two nasal tubes, so that the outer port of the nasal tube is always close to the nostrils. Then determine the position of the mask, wrap the two pieces of the fixing belt around the back of the head, and stick the fine and rough surfaces of the two pieces of belts to each other, so that the oxygen tube mask is stably worn on the face, mouth and nose, and the patient can breathe smoothly. The inhaled oxygen is inhaled unidirectionally from the oxygen inlet tube and the oxygen semicircular tube, and the exhaled nitrogen dioxide and secretions are discharged unidirectionally from the waste gas semicircular tube and the waste gas exhaust tube. In this way, no waste gas and secretions will be re-inhaled, and the patient will not be choked. At the same time, the nasal tube does not touch the nasal cavity and will not irritate the nasal cavity.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) Separating the oxygen intake and waste gas exhaust channels effectively improves the patient's oxygen inhalation effect, while effectively avoiding the re-inhalation of the patient's exhaled waste gas and secretions, thereby avoiding choking the patient.

[0018] (2) A one-way oxygen inlet and a one-way exhaust outlet are provided. Oxygen can only enter from the one-way oxygen inlet. But cannot enter from the exhaust port; waste gas and secretions can only be discharged from the one-way exhaust port, but cannot be discharged from the one-way oxygen inlet, effectively realizing the diversion of oxygen and waste gas.

[0019] (3) The nasal tube only approaches or touches the outer opening of the nostril and does not touch the nasal cavity, which effectively avoids irritation to the nasal cavity and improves the patient's comfort. BRIEF DESCRIPTION OF THE DRAWINGS
