Abstract

The utility model relates to a surgical anesthesia assisting device in medical instruments, specifically to a disposable moldable endotracheal intubation guide tube core, comprising a plastic flexible tube. The front end of the plastic flexible tube is provided with an LED lamp or a miniature bulb; the tail of the flexible tube is provided with a battery and a switch; the LED lamp or miniature bulb is connected with the battery through leads; the inner cavity of the flexible tube is provided with a flexibly moldable metal tube core or a plastic tube core; the metal tube core may be a metal solid tube core or a metal hollow tube core; and the plastic tube core is a hollow tube core. The surgical anesthesia assisting device has a simple structure and low cost, is easy to operate, is safe and reliable, and can completely replace a conventional metal endotracheal intubation guide tube core; requires no operation of lifting up an epiglottis with a laryngoscope during use and thus reduces stimulus applied to a patient; and, during difficult blind intubation, enables intubation through direct view with the laryngoscope and requires no replacement of the tube core again, thereby being suitable for extensive clinical promotion and application.

Description

Disposable plastic type tracheal intubation guiding tube core

Affiliated technical field

This utility model relates to a kind of medical apparatus and instruments surgery anesthesia auxiliary device, specifically a kind of disposable plastic type tracheal intubation guiding tube core.

Background technology

In the prior art, when patient need anaesthetize sb. generally, generally be to adopt endotracheal tube to cooperate laryngoscope, from patient's mouth, insert in the trachea.The shortcoming of this method is to misplug into the esophagus phenomenon often to take place.As everyone knows, the glottis top has one " epiglottis ", and epiglottis opens wide when breathing; When diet, " epiglottis " then blocks glottis, and when opening mouthful; The doctor generally can only see " epiglottis ", " preceding associating ", indistinctly can see vocal cords, also can't see clearly Chu with regard to the crotch of saying trachea and esophagus; Even use laryngoscope at present, the throat of also can only throwing light on still can't see the branch of trachea and esophagus and locates again.Therefore, mispluging into esophagus and often take place, generally is to insert or simply cut throat again, causes very big misery to patient.For having infantilism epiglottis, super-huge epiglottis, high glottis and the glottis person of leaning forward, and epiglottis, when all can not exposing, then can't insert in glottis.

Luminous tracheal intubation guiding tube core is a flexible metal catheter; Front end is equipped with bulb; Afterbody is furnished with battery and switch, during intubate, endotracheal tube is enclosed within on the tracheal intubation guiding tube core; According to the anatomical structure of human body pars oralis pharyngis, luminous tracheal intubation guiding tube core is bent into a J-shaped (referring to Fig. 3).During intubate, utilize the principle of neck soft printing opacity to observe in the guiding endotracheal tube entering trachea,, thereby can effectively improve successful intubation for tracheal intubation under the blind spy provides visual index.Make with lubricator help tracheal intubation guiding tube core through and make conduit be prone to break away from.

Luminous tracheal intubation tube core intubate is used traditional direct laryngoscope intubate than direct laryngoscope easy master more, need make ccavum oropharygeum " three axis " become straight line, accomplish down in direct-view, have only the doctor who passes through specialized training to grasp.During luminous tracheal intubation tube core intubate, its bending shape is consistent with the ccavum oropharygeum structure curve, does not need incidence to cooperate, as long as see hot spot at ring first film place, can smoothly endotracheal tube be pushed in the trachea.As long as the Anesthetist through formal training has seen once luminous tracheal intubation tube core intubate, with regard to the ability independent operation, about average intubation time 25s.Successful intubation＞98%.

China utility model patent CN9321938.3 discloses a kind of therapeutic medical extension and tropism tracheal intubation pipe that has bulb, and it is bent hollow pipe head, hollow pipe pavilion, link and on and off switch portion, stretches to bend sliding axle and stretch and bend control and buckle, stretch handle 6 most of institutes of bending transmission steel wire, built-in battery slightly and form by having stretching of bulb.When starting power button, bulb is just bright, through brake sliding bridge is slided forward or backward, affects to stretch to bend the transmission steel wire and make the lamp socket of hollow pipe head stretch or bend, and adjusts intubate head camber at any time, so that insert in the trachea smoothly.

Above-mentioned tracheal intubation guiding tube core, complex structure, cost is higher, need be repeatedly used, because its metal die is bent with repeatedly and possibly ruptures, the bulb of tracheal intubation guiding tube core front end also might rupture or get loose when intubate and fall in the trachea.In addition, owing to be repeatedly used,, might cause the cross infection of infectious disease if sterilization is not thorough.

Summary of the invention

In order to address the above problem; This utility model provides a kind of cheapness; Can disposable tracheal intubation guide tube core, solve the problem that the prolonged and repeated use of existing tracheal intubation guiding tube core is produced, stop the possibility of infectious disease cross infection simultaneously.

The technical scheme of this utility model is: disposable tracheal intubation guiding tube core; Comprise a plastic flexible pipe; Its front end is equipped with LED lamp or pea lamp; Said flexible pipe afterbody is furnished with battery and switch, and said LED lamp or pea lamp both positive and negative polarity link to each other with battery through lead, and flexible moulding metal die or plastic wick are housed in the said flexible pipe inner chamber.

Said metal die comprises solid tube core of metal and metal hollow tube core.Said plastic wick is hollow tube core.

As further replenishing of such scheme, depth adjuster is equipped with in said plastic flexible pipe outside, be used for according to the high length of tube of trachea differently regulate, A/C.

Be further replenishing of such scheme, said switch is the blade inserting insulated switch, is used for cutting off or said LED lamp of conducting or pea lamp place circuit.

The beneficial effect of this utility model is simple in structure, and is easy to operate, safe and reliable; With low cost, can substitute existing metal tracheal intubation guiding tube core fully, reduced the risk that intubate suppresses the patient vessel; Solved the material ageing problem that the prolonged and repeated use of existing tracheal intubation guiding tube core is produced, stopped the possibility of the cross infection of infectious disease, need not during use to provoke epiglottis with laryngoscope; Minimizing like the blind tracheal intubation difficulty, can combine laryngoscope directly to look at intubate down straight to patient's stimulation; Need not to change again tube core, be worth extensively promoting the use of clinical.
