Mouth gag

Abstract

The invention discloses a mouth gag. The mouth gag comprises a supporting base and a threaded rod. L-shaped supporting arms are hinged to the two ends of the supporting base and sleeved with protective sleeves in a matched mode, the mouth gag further comprises nuts in threaded fit with the tail ends of the L-shaped supporting arms, trays are installed on the nuts, and when the L-shaped supporting arms are placed in the oral cavity of a patient, the two trays are arranged to make contact with the upper jaw and the lower jaw of the patient respectively. When the L-shaped supporting arms are taken out of the protective sleeves, after the nuts are in threaded fit with the tail ends of the L-shaped supporting arms, the trays are fixed to the tail ends of the L-shaped supporting arms; when the L-shaped supporting arms stretch deep into the oral cavity of the patient, the trays make direct contact with the upper jaw or the lower jaw of the patient, and the contact area between the L-shaped supporting arms and the upper jaw or the lower jaw of the patient is increased, so that stress, acting inside the oral cavity, of the L-shaped supporting arms is dispersed to reduce the pressure, borne by the oral cavity of the patient, of the L-shaped supporting arms, and the post-operation sequelae of the patient are reduced.

Description

technical field [0001] The invention relates to a medical emergency equipment, in particular to a gag. Background technique [0002] Mouth gag, also known as mouth gag, is a device used to open the mouth when breathing is difficult or unconsciousness requires gastric lavage. The body of the gag is U-shaped, and two ends of the gag body are fixedly connected with a handle respectively. The opener body is elastic, and the two side arms of the opener body can be bent toward the inside or outside of the opener body when pressed by external pressure. When the external pressure disappears, the two side arms of the opener body recover again. to the original position. [0003] The side arm of the existing mouth gag is very sharp, which is easy to scratch the user or patient during use, and the side wall of the gag needs to be disinfected before use, that is, soaked in a disinfectant for a certain period of time to prevent infection of the patient , but it is precisely because o...

Problems solved by technology

[0003] The side arm of the existing mouth gag is very sharp, which is easy to scratch the user or patient during use, and the side wall of the gag needs to be disinfected before use, that is, soaked in a disinfectant for a certain period of time to prevent infection of the patient , but it is precisely because of this necessary step and the expansion of the patient's mouth during use that it greatly affects the efficiency of first aid, which in turn causes the patient to lose the best chance of rescue
