Oxygen supply connector and mask using same

Abstract

The invention relates to an oxygen supply connector and a mask using the connector. The oxygen supply connector comprises two parts such as an inner fixing piece (3) and an outer fixing piece (4), a pressure sensing channel (1), an oxygen supply channel (5), an induction opening and an oxygen supply nozzle (10) are arranged on the inner fixing piece (3) and the outer fixing piece (4) respectively,lung type oxygen supply can be achieved through cooperation of the oxygen supply connector and a negative pressure control valve, and emergency oxygen supply can be achieved by closing the negative pressure control valve. The oxygen supply connector is sewn on the mask, so that the mask can be used as a conventional mask, can also be used as an emergency oxygen supply mask, and is connected withoxygen supply equipment to supply oxygen to a patient. The oxygen supply connector and the mask are low in cost and convenient to produce on a large scale, the mask serves as conventional medical equipment, the problem of excessive capacity is not likely to occur, the problem that a special oxygen supply mask is insufficient can be solved in emergency of medical treatment, normal operation of medical treatment is guaranteed, and the cost needed by a user is reduced.

Description

technical field [0001] The invention relates to the technical field of oxygen supply equipment, in particular to an oxygen supply interface and a mask using the interface. Background technique [0002] Mask is a commonly used protective equipment, which is divided into daily protective equipment and medical protective equipment according to the grade of production products. It is used to prevent harmful substances such as viruses or dust from being directly inhaled into the human body along with the air, thereby causing damage to the human body. Oxygen supply equipment is a kind of equipment that can supply oxygen to patients with weakened lung function or people who enter the hypoxic environment. It usually needs to use a special oxygen supply mask, because there is not much demand for special oxygen supply masks under normal conditions. Therefore, in a medical emergency, the special oxygen supply mask is prone to insufficient supply, so that the patient cannot receive the ...

AI Technical Summary

Problems solved by technology

At present, the oxygen supply for this kind of people needs to go through a separate oxygen supply equipment, and the oxygen supply oxygen cylinder can be used multiple times, but the oxygen supply mask needs to be processed after recycling, so the recycling cost is high, so it is directly discarded It will also cause a lot of waste
