Abstract
The invention provides an auxiliary trachea cannula oropharynx dilator, aiming at solving the problem that trachea cannula is difficult since anatomical structures such as the oropharynx, the glottis and the like of patients with narrow oropharynx, laryngeal edema and the like caused by short necks, obesity, fat tongue bodies and the like can not be easily exposed in a clinical oral trachea cannula process. The auxiliary trachea cannula oropharynx dilator is characterized by comprising a lower support plate and an upper support plate which are articulated with each other by a rotating shaft, wherein a torsion spring is sheathed on the rotating shaft; the two ends of the torsion spring are respectively blocked and connected with the lower support plate and the upper support plate; the lower support plate is provided with a trachea insertion long opening. The auxiliary trachea cannula oropharynx dilator can be used for dilating the oropharynx when the patient needs emergency intubation, so that the glottis can be fully exposed; the auxiliary trachea cannula oropharynx dilator can effectively increase the success rate of trachea cannula especially for the patients who have narrow oropharynx, laryngeal edema and the like so as to be difficult in cannula, thus having the function of rescuing in time.
Description
technical field:
The present invention relates to a kind of auxiliary trachea cannula oropharynx dilator, belong to technical field of medical instruments.
background technology:
Emergency trachea intubation technique has become cardio-pulmonary resuscitation and with the important measures in the Severe acute disease patient rescue process of respiratory dysfunction.Endotracheal intubation is important rescue technology conventional in rescue service, be in management of respiratory most widely used general, the most effectively, one of means the most efficiently, to rescue patient life, reduce case fatality rate and play vital effect.Pass through in orotracheal tube process clinical, often have the patients such as some oropharynxs are narrow and small, laryngeal edema, the anatomical structure such as oropharynx and glottis can not expose, and causes tracheal intubation difficulty, current way, after exposing glottis by laryngoscope under direct-view, conduit direct oral cavity is inserted tracheal strips.But play exposure effect because laryngoscope is single direction lift oropharynx tissue, do not possess expansion, strut the effect of throat, appear glottis still more difficult, particularly when clinical emergency treatment, if successfully can not insert endotracheal tube in time, patient often faces life danger.The branchofiberoscope of tracheal intubation " goldstandard " even overcome a difficulty, also needs certain oropharynx exposed space to show and guide cannula.
summary of the invention:
The object of the invention is to provide a kind of auxiliary trachea cannula oropharynx dilator for above-mentioned Problems existing, can help to strut oropharynx position when implementing endotracheal intubation clinically, fully expose glottis fast, thus quick intubate, be beneficial to patient and rescue.
Above-mentioned object is realized by following technical scheme:
Auxiliary trachea cannula oropharynx dilator, comprise by the hinged lower fagging of rotating shaft and upper fagging, described rotating shaft is set with a torsion spring, described torsion spring two ends respectively with described lower fagging and upper fagging clamping, described lower fagging has endotracheal tube and inserts long opening.
Described auxiliary trachea cannula oropharynx dilator, is provided with positioning checkpoint between described lower fagging and upper fagging.
Described auxiliary trachea cannula oropharynx dilator, described positioning checkpoint comprises cutting ferrule, and one end of described cutting ferrule is sleeved on described lower fagging, and the two ends of described cutting ferrule have the pawl fitted tightly with upper fagging.
Described auxiliary trachea cannula oropharynx dilator, the lower end inside of described lower fagging is provided with photographic head, described photographic head connects display screen by the data wire be built in described lower fagging, and described display screen is arranged on described upper fagging or the upper end of lower fagging.
Described auxiliary trachea cannula oropharynx dilator, described lower fagging is provided with groove, and described groove is positioned at described rotating shaft bottom, and the part that described upper fagging is positioned at below described rotating shaft can be embedded in inside described groove.
Described auxiliary trachea cannula oropharynx dilator, described lower fagging and described upper fagging are convexly curved, and the lower end of described lower fagging and described upper fagging is arc-shaped.
Described auxiliary trachea cannula oropharynx dilator, the width that described endotracheal tube inserts long opening is 1-2cm.
Beneficial effect:
1. the present invention can play when needs of patients tracheal intubation the effect strutting pars oralis pharyngis tissue, and glottis is fully exposed, and particularly the patient of the difficult intubation such as, laryngeal edema narrow and small for oropharynx, can play the effect of rescuing in time, save intubation time.
2. be provided with positioning checkpoint between lower fagging of the present invention and upper fagging, after the pars oralis pharyngis tissue strutting patient with dilator of the present invention, positioning checkpoint can fix the opening width of lower fagging and upper fagging, operates to facilitate the tracheal intubation of rear thread.
3., in order to avoid endotracheal tube being inserted esophagus in the process of intubate by mistake, the lower end inside of lower fagging of the present invention is provided with photographic head, can facilitate the direction and position of clearly observing intubate.The data wire of photographic head of the present invention is built in described lower fagging, neither affects intubation, and operation can be made again visual, and make intubation more accurate, efficiency is higher.
4. under the present invention, fagging is provided with groove in described rotating shaft bottom, the part that described upper fagging is positioned at below described rotating shaft can be embedded in inside described groove, such structural design can facilitate the smooth insert port of dilator pharyngeal, can avoid again the soft tissue clipping to patient's pars oralis pharyngis.
5. the lower end of lower fagging of the present invention and upper fagging is all designed to arc-shaped, and edge is smooth and easy, smooth, avoids acute angle stabbing during insertion to patient's pars oralis pharyngis.
6. the too narrow meeting of width of inserting long opening due to endotracheal tube makes difficult intubation, and the width that endotracheal tube inserts long opening is excessive, the soft tissue of patient's pars oralis pharyngis can enter endotracheal tube and insert long opening, the insertion of endotracheal tube can be affected equally, therefore the present inventor is through repeatedly clinical trial discovery, and the width that trachea inserts long opening is that 1-2cm is best.
7., because the present invention is in order to auxiliary oral trachea cannula, in order to more meet the feature of organization of human body, make per os insert trachea and be more prone to, lower fagging of the present invention and upper fagging are designed to arc-shaped.
accompanying drawing illustrates:
