Description

A kind of adjustable first-aid gag

Technical field

This utility model belongs to the medical mouth gag technical field, particularly a kind of adjustable first-aid gag.

Background technology

Gag generally is used for stupor, and what the special examined that must dehisce and respiratory tract obstruction caused suffocates, when urgent first aid, open the patient trismic on lower jaw.

Domestic and international existing gag has jaw type, Ding Shi and wears Vickers etc., and these gags all need to just can be put the oral cavity into and carry out aperture and fix when tooth opens certain aperture.But when patient lay in a comatose condition, gag commonly used just was difficult to open the trismic upper lower jaw of patient.When emergency, just its tooth can only be knocked out so that gag is injected the oral cavity check and treat.But when first aid, time is life, and each minute each second is especially important all, yet the time of getting tooth just may have been delayed best rescue time.Moreover, the tooth that takes down can not regenerated, and brings some inconvenience for the later life of patient.

The utility model content

Technical problem to be solved in the utility model provide a kind of simple to operate, can not damage patients teeth adjustable first-aid gag.

In order to solve the problems of the technologies described above, this utility model provides following technical scheme:

A kind of adjustable first-aid gag comprises support, handle, fulcrum part; Its medium-height trestle is circular arc, and respectively there is a holder at the support two ends; Support is fixed on an end of handle; Fulcrum partly is fixed on the handle.

Further, described support is provided with the expansion link of regulating the gag size.

This utility model is beneficial effect compared with prior art:

This utility model is simple to operate, only needs the holder at support two ends to insert last molar slit afterwards, and fulcrum is placed on the lower jaw place, holds handle, gets final product toward pressing down.Can patient's tooth not damaged in whole opening process simultaneously.When tooth is closed the First Aid of stupor, can not only save rescue time, also bring convenience to the healthcare givers.

Because everyone oral cavity size is different, at support expansion link is set, just can regulate the gag size as required, to be fit to the patient's mouth size.
