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 through hole. 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 assisted gas cannula oropharynx dilator, belong to technical field of medical instruments.
Background technology:
The emergency trachea intubation technique has become cardio-pulmonary resuscitation and has reached with the important measures in the anxious Cavity in Critical Patients rescue process of respiratory dysfunction.Endotracheal intubation is important rescue technology commonly used 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.In the clinical orotracheal tube intubate process of passing through, the patients such as some oropharynxs are narrow and small, laryngeal edema are often arranged, and the anatomical structures such as oropharynx and glottis can not expose, and cause tracheal intubation difficulty, current way is after by laryngoscope, exposing glottis under looking at straight, the conduit direct oral cavity to be inserted in trachea.But because laryngoscope is that single direction lifts the oropharynx tissue and plays the exposure effect, do not possess expansion, strut the effect of throat, appear glottis still more difficult, particularly when clinical emergency treatment, if can not successfully insert in time endotracheal tube, the patient often faces life danger.The branchofiberoscope of the tracheal intubation even overcome a difficulty " goldstandard ", also need certain oropharynx exposed space to show and guide cannula.
Summary of the invention:
The objective of the invention is provides a kind of assisted gas cannula oropharynx dilator for the problem of above-mentioned existence, while implementing endotracheal intubation clinically, can help to strut the oropharynx position, fully exposes fast glottis, thereby quick intubate is beneficial to the patient and rescues.
Above-mentioned purpose realizes by following technical scheme:
Assisted gas cannula oropharynx dilator, comprise by the hinged lower fagging of rotating shaft and upper fagging, suit one torsion spring in described rotating shaft, described torsion spring two ends respectively with described lower fagging and upper fagging clamping, on described lower fagging, have endotracheal tube and insert long through-hole.
Described assisted gas cannula oropharynx dilator, be provided with positioning checkpoint between described lower fagging and upper fagging.
Described assisted gas cannula oropharynx dilator, described positioning checkpoint comprises cutting ferrule, and an 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 assisted gas cannula oropharynx dilator, the inboard, lower end 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 the upper end of described upper fagging or lower fagging.
Described assisted gas cannula oropharynx dilator, be provided with groove on described lower fagging, and described groove is positioned at described rotating shaft bottom, and described upper fagging is positioned at the following part of described rotating shaft can be embedded in described groove the inside.
Described assisted gas 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 circular-arc.
Described assisted gas cannula oropharynx dilator, the width that described endotracheal tube inserts long through-hole is 1-2cm.
Beneficial effect:
1. the present invention can play the effect that struts the pars oralis pharyngis tissue when the needs of patients tracheal intubation, makes glottis fully expose, and particularly the patient of the difficult intubation such as, laryngeal edema narrow and small for oropharynx, can play the effect of timely rescue, saved intubation time.
2. between lower fagging of the present invention and upper fagging, be provided with positioning checkpoint, after with dilator of the present invention, strutting patient's pars oralis pharyngis tissue, positioning checkpoint can be fixed the opening width of lower fagging and upper fagging, to facilitate the tracheal intubation operation of rear thread.
3. for fear of mistake in the process of intubate, endotracheal tube is inserted to esophagus, the inboard, lower end of lower fagging of the present invention is provided with photographic head, can facilitate direction and the position of clearly observing intubate.The data wire of photographic head of the present invention is built in described lower fagging, neither affects intubate operation, can make again to operate visual, makes the intubate operation more accurate, and efficiency is higher.
4. under the present invention, in described rotating shaft bottom, be provided with groove on fagging, described upper fagging is positioned at the following part of described rotating shaft can be embedded in described groove the inside, such structural design can facilitate the smooth insert port of dilator pharyngeal, can avoid clipping to again the soft tissue of patient's pars oralis pharyngis.
5. the lower end of lower fagging of the present invention and upper fagging all is designed to circular-arcly, and edge is smooth and easy, smooth, avoids acute angle stabbing to patient's pars oralis pharyngis during insertion.
6. the too narrow meeting of width due to endotracheal tube insertion long through-hole makes difficult intubation, and the width of endotracheal tube insertion long through-hole is excessive, the soft tissue of patient's pars oralis pharyngis can enter endotracheal tube and insert long through-hole, can affect the insertion of endotracheal tube equally, therefore the inventor is through repeatedly clinical trial discovery, and the width that trachea inserts long through-hole is 1-2cm the best.
Due to the present invention for auxiliary oral trachea cannula, in order more to meet the characteristics 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 circular-arc.
The accompanying drawing explanation:
Fig. 1 is plan structure schematic diagram of the present invention.
Fig. 2 is left view of the present invention.Clearer for the expression that makes all parts, the dilator in figure is in half softened state.
Fig. 3 is the structural representation of positioning checkpoint of the present invention.
In figure: 1, rotating shaft, 2, lower fagging, 3, upper fagging, 4, torsion spring, 5, long through-hole, 6, positioning checkpoint, 7, infrared camera, 8, display screen, 9, groove, 6-1, cutting ferrule, 6-2, pawl.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.Should understand the following specific embodiment only be used to the present invention is described, limit the scope of the invention and be not used in.
Embodiment 1:
