Abstract

The utility model relates to a reinforced trachea laryngeal mask insertion assisting device, which is characterized by comprising a handle, a splicing structure, a convex-surface vane and a cuboid structure, wherein the handle is provided with a small hole; the splicing structure is arranged on the lower section of the handle; the vane is provided with three linear bumps; the cuboid structure is attached to the narrow end of the vane and is provided with a hole; and the handle and the vane are connected with each other in an insertion way. During use, the handle and the vane are assembled in an insertion way, and the vane is used for lifting a tongue root and a tongue body, so that the perimeters of an oral cavity and a palatoglossal arch are expanded, a laryngeal mask entrance channel is expanded, the laryngeal mask insertion resistance is reduced, a laryngeal mask can successfully reach a pharyngeal cavity, the defect of difficulty in inserting a reinforced trachea laryngeal mask due to a soft ventilation tube is overcome, insertion loss is reduced, the problem that the pharyngeal cavity cannot be successfully delivered to the pharyngeal cavity since the index finger of an operator is not long enough in a standard 'index finger assisting method' is solved, and convenience is brought to laryngeal mask insertion operation.

Description

Reinforced tube type laryngeal mask inserts auxiliary device

Technical field

The utility model relates to a kind of laryngeal mask and insert auxiliary device, what be specifically related to is a kind of insertion auxiliary device of reinforced tube type laryngeal mask.

Background technology

Laryngeal mask is an airway pressure device on a kind of novel glottis, not only is used for difficult airway and the emergency patient ventilates temporarily, also has been widely used in the general anesthesia airway management, have damage little, stimulate little advantage.

In order to improve the purposes of laryngeal mask; Make things convenient for its application in ENT dept. and operation on neck; The particularly exploitation of third generation laryngeal mask, reinforced tube type laryngeal mask arises at the historic moment, because reinforced tube type laryngeal mask snorkel softness is flexible; Causing reinforced tube type laryngeal mask to insert difficulty increases, such as: conventional criteria " forefinger auxiliary law " operator possibly forefinger length can't send to pharyngeal cavity with laryngeal mask inadequately smoothly; Can't overcome resistance when seal wire is inserted breather as auxiliary placement device and insert difficulty.And adopt baroque auxiliary placement device, and can't disposablely use owing to cost an arm and a leg, possibly cause cross infection.

The utility model content

To the difficulty that reinforced tube type laryngeal mask exists during insertion, this utility model provides purpose to be to provide a kind of reinforced tube type laryngeal mask to insert auxiliary device, and the blade through auxiliary device is with lifting on the root of the tongue and the tongue body; Enlarge oral cavity and palatoglossal arch Zhou Jing, make reinforced tube type laryngeal mask under low resistive state, arrive pharyngeal cavity, need not the operator and point auxiliary; Reduce reinforced tube type laryngeal mask and insert difficulty; Reduce the oropharynx mucosa injury, simultaneously employed insertion auxiliary device adopts the medical plastic material, and is simple in structure; Convenient for production, cheap.

To achieve these goals, this utility model is to realize through following technical scheme:

Reinforced tube type laryngeal mask inserts auxiliary device; It is characterized in that; Said auxiliary device comprise with the handle of aperture, be arranged on the handle hypomere connected structure and convex surface have three linear projections blade, be attached to the narrow end of blade rectangular structure with holes, said handle is connected with inserted mode with blade.

Above-mentioned reinforced tube type laryngeal mask inserts auxiliary device, and wherein, there is an aperture in said handle stage casing, and hypomere has a fixed dam, fixed knob, two prismatic latches.There is an aperture in said fixed dam central authorities, and said fixed knob can insert the aperture internal rotation, makes knob front end forward-reverse.

Above-mentioned reinforced tube type laryngeal mask inserts auxiliary device, and wherein, the narrow end of said blade has two prismatic jacks and a circular knob jack with rectangular structure on the said rectangular structure.

Above-mentioned reinforced tube type laryngeal mask inserts auxiliary device, and wherein, said blade is the capable leaf shape of the wide arc in the left narrow right side, and said blade is provided with concave surface and convex surface; Said forward face is covered with the dot of projection, and said blade convex surface has three capable projections of the line with the blade axis.

Above-mentioned reinforced tube type laryngeal mask inserts auxiliary device, and wherein, after said handle and blade inserted and be connected, angle between the two was 80 to spend.

The beneficial effect that this utility model reaches is following:

This utility model is connected with blade handle in use to insert, utilize its blade with lifting on the root of the tongue and the tongue body; Enlarge oral cavity and palatoglossal arch Zhou Jing; Make to arrive pharyngeal cavity under the reinforced tube type laryngeal mask low resistive state smoothly, reduce the oropharynx mucosa injury, reduce reinforced tube type laryngeal mask and insert difficulty; Overcome standard " forefinger auxiliary law " and can't smoothly laryngeal mask have been sent to the difficulty of pharyngeal cavity when not enough, made things convenient for the insertion of reinforced tube type laryngeal mask because of operator's forefinger length.

It is novel to specify this use below in conjunction with accompanying drawing and the specific embodiment.

Description of drawings

Fig. 1 is the front view of this utility model;

Fig. 2 is the separately figure of handle and 2 main bodys of blade;
