CN201132002Y - Oropharynx passage coping with the trachea cannula imbedding esophagus - Google Patents

Abstract

The utility model relates to an oropharynx airway for providing a tracheal cannula to be implanted into an esophagus, which belongs to the tracheal cannula field. The main body part adopts a hollow airway, the airway forms a wedge-shaped air filled air bag after being filled with air, and a cannula passage which can penetrate through the tracheal cannula impenetrate in the bag. Hard rings are respectively arranged at the upper and lower ends of the cannula passage, the inner wall of the passage adopts one part of the air filled air bag, and the passage is under a sealed state when the tracheal cannula is not nested. When the tracheal intubation is adopted, the tracheal cannula is positioned into the esophagus, and the device can be nested on the cannula inserted through the cannula passage, and can be implanted into the oropharynx part under the guiding action of the tracheal cannula. By using the airway management of the utility model, the tracheal cannula inserted wrongly is not required to be pulled out, under the guiding action of the tracheal cannula, the success ratio of one-time implantation can be improved, so that the damage of oropharynx mucosa can be reduced, the time for hypoxia can be shortened, and the bloating of stomach and the regurgitation and aspiration can be reduced; the wedge-shaped inflatable air bag reduces the overspill of gas; thereby the oropharynx airway is a quick and effective tool for emergency resuscitation and difficult airway management.

Description

The reply tracheal intubation is inserted the oropharyngeal airway of esophagus

Technical field

This utility model relates to imports the intravital apparatus of people with medium, particularly influences apparatus, the especially tracheal intubation of patient respiration system with gas treating process.

Background technology

At present, difficult airway circulation of qi promoting cannula has the probability of 0.05%-0.35% that tracheal intubation is inserted esophagus, and need extract intubate circulation of qi promoting cannula art once more this moment.Intubate can cause the pars oralis pharyngis mucosa injury repeatedly, causes serious upper respiratory tract to block, and patient's life is on the hazard.In addition, can also be after extracting tracheal intubation, airway carries out airway management on the use glottis.Wherein first-selected is laryngeal mask, and after inserting, inflating, air bag and human body pars oralis pharyngis anatomical structure match, and can set up airtight relatively, and the isolated airway of esophagus rapidly.The oropharyngeal airway of band air bag is similar to the laryngeal mask principle.No matter esophagus trachea associating conduit is inserted trachea and still be esophagus and can utilize different bladder is inflated and set up airway rapidly and carry out mechanical ventilation for the patient.At first can extract about 20 seconds time of waste in this operation of tracheal intubation when using these airways, secondly tube drawing can cause damage by the boil on the nape opposite the mouth pharyngeal mucosa, increases upper respiratory tract and blocks odds; In addition, every kind of airway is inserted all the odds of failing once more, has increased the irreversible brain injury of easy generation of anoxybiotic time of patient like this, and repeatable operation makes the pars oralis pharyngis myxedema simultaneously, increases the danger that respiratory tract obstruction takes place.During laryngeal mask airway, gas enters digestive tract easily under the effect of pressure, cause abdominal distention, anti-stream easily takes place during tube drawing, inhale by mistake; The oropharyngeal airway of band air bag, because air bag and human anatomic structure are misfitted, odds is higher.Esophagus trachea associating conduit causes hypoventilation easily because spherical envelope and pars oralis pharyngis anatomical structure are identical bad.

Summary of the invention

Thereby in order to overcome difficulties the shortcoming that to extract intubate air flue seal difference when increasing that the anoxia time, the boil on the nape opposite the mouth pharyngeal mucosa caused damage and mechanical ventilation simultaneously when air flue circulation of qi promoting cannula is inserted esophagus, this utility model is inserted the advantage that inferior position that esophagus can't ventilate is converted into sealing digestive tract utilization ventilation with tracheal intubation, improves the airtight row that air bag improves air flue simultaneously.

The technical scheme that its technical problem that solves this utility model adopts is: its main part is the airway of hollow, the encirclement gas cell of airway, and running through in the gas cell can be by the cannula passage of tracheal intubation, gas cell inflation back wedgewise.The cannula passage upper and lower end is the hard ring of diameter 40-85 millimeter, high 10-30 millimeter, and the cannula passage inwall has gas cell to constitute, and this cannula passage does not become closed state when inserting tracheal intubation.The airway veutro is arranged 1-4 the passage that diameter is the 5-15 millimeter along the airway longitudinal axis in the 20-60 millimeter scope of glottis end, still keep the unobstructed of airway when making airway glottis end by tongue body and the obstruction of other soft tissues.At the airway veutro markings of one projection are arranged in the 20-60 millimeter scope of mouth end, judge by the relative distance of it and patient's front tooth whether this utility model is in place.

Use this utility model to carry out airway management, do not need to extract the tracheal intubation of misplace, reduced the damage of pars oralis pharyngis mucosa, shortened the anoxybiotic time of patient; Many tracheal intubatioies are guided, make probability that this utility model once inserts success far above airway on other glottises, tracheal intubation obstruction esophagus simultaneously, the generation of minimizing surge gas, reflux erroneous aspiration.Wedge shape air bag and human body pars oralis pharyngis anatomical structure match, and reduced gas excessive to oral cavity, nasal cavity.

The specific embodiment

As shown in Figure 1, its main part is the airway 1 of hollow, the encirclement gas cell 2 of airway, and running through in the gas cell 2 can be by the cannula passage 3 of tracheal intubation, gas cell 2 inflation back wedgewises.Cannula passage 3 upper and lower ends 4,5 are the hard ring of diameter 40-85 millimeter, high 10-30 millimeter, and cannula passage 3 inwalls have gas cell 2 to constitute 3 one-tenth closed states of this cannula passage when not inserting tracheal intubation.Airway veutro 10 is arranged 1-4 the passage 8 that diameter is the 5-15 millimeter along airway 1 longitudinal axis in the 20-60 millimeter scope of glottis end 6, still keep the unobstructed of airway when making airway 1 glottis end 6 by tongue body and the obstruction of other soft tissues.At airway veutro 10 markings 9 of a projection are arranged in mouthful 20-60 millimeter scope of end 7, judge by the relative distance of it and patient's front tooth whether this utility model is in place.

In the embodiment shown in Figure 2, tracheal intubation 12 enter the esophagus by mistake 11 during circulation of qi promoting cannula art, this utility model is enclosed within on the tracheal intubation 12 by cannula passage 3, under tracheal intubation 12 guiding, this utility model is slowly inserted, insert when this utility model and to be obstructed or markings 9 when aliging, illustrate and insert success with patient's front tooth.After gas cell 2 inflated, the road junction end 7 of will ventilating is linked with respirator just can carry out artificial ventilation.
