Buckle-free face shield

Abstract

The present invention discloses a buckle-free face shield. The buckle-free face shield comprises a shield body, and an upper end of the shield body is provided with an air feed pipe for introducing oxygen. The buckle-free face shield also comprises a shield pad and a buckle member for fixing the face shield, one end of the buckle member is movably hinged to a side wall outside the air feed pipe, the other end of the buckle member serves as an action end of a buckle, the shield pad is prepared by soft materials and fixed at an inner side edge of a lower end of the shield body, and the shield pad is seamlessly attached to the face when the buckle-free face shield is worn on the face of a patient. Through the buckle member mainly formed by a diagonal rod and a cross bar, the face shield can be well buckled on the face of the patient. When the buckle-free face shield is used, the face shield is aligned to the mouth and nose of the patient and tightly pressed, then the cross bar of the buckle member is buckled at the jaw of the patient, and operation is complete. The operation is easy, convenient and effortless, pressing force on the mouth and nose of the patient caused by wearing the breathing face shield is reduced, and patient comfortableness is increased. A traditional air bag structure is replaced by a peg collar-shaped shield pad formed by silica gel, and air-tightness and fit degree of the face shield are effectively enhanced.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical breathing mask, in particular to a buckle-free mask that does not need to be pressed hard. Background technique [0002] As we all know, breathing masks must be used during surgical anesthesia and rescue. Most of the medical masks currently on the market are inflatable cushion products made of PVC. During the wearing process, the medical staff need to exert a lot of effort to buckle the mask to the airtight state, which will cause a large squeeze on the patient's mouth and nose; at the same time, it also needs to be combined with the fixing of the four headbands. It is extremely inconvenient to use with several steps of operation procedures. [0003] In order to overcome the above-mentioned defects, some improved medical masks have appeared on the market, such as the Chinese Utility Model Patent No. 201220562610.7, which discloses a convenient pressing breathing mask, which include...

Problems solved by technology

Although the medical mask with this structure can greatly reduce the labor load of medical staff and has the advantages of convenient pressing and labor saving, the part in contact with the human body is an airbag structure, and the contact between the airbag and the human body is "point-to-point", and oxygen is easily transferred from the mask to the human body. The patient contact surface leaks, the seal is not good, and it is still troublesome to buckle and wear
