Summary of the invention
In order to overcome the shortcoming of existing tracheal intubation, this utility model provides double braid covering capsule tracheal intubation.This intubate is passed through perforate on tracheal intubation, cover capsule and overcoat capsule in the tapping suit, and the space between air injection pipe and the two cover capsules communicates, and solves tracheal intubation sleeve bag gas-filling and the technical problem that prevents interior gas leak of air flue and air flue mucosa injury.
The scheme that this utility model technical solution problem is adopted is:
On one section tube wall of tracheal intubation, be provided with passage; Cover capsule in outside the tracheal intubation at passage position, being set with; Outside interior cover capsule, be set with the overcoat capsule, on air injection pipe, be connected with vent valve, gas injection capsule and gas injection valve in turn, be provided with gas injection port on gas injection valve top; Air injection pipe is passed anti-again trachea cannula wall behind the tracheal intubation wall, and its gas outlet communicates with space between interior cover capsule and the overcoat capsule.
Good effect the utlity model has convenient insertion person's windpipe, and the overcoat capsule is closely contacted with the person's windpipe wall, thereby, reduce the excessive generation that causes person's windpipe infringement or the too small bad sealing of pressure to cause gas leak phenomenon of cover bag pressure power.Suitable in the human body diseases therapeutic process, use when tracheal intubation or tracheotomy.

The specific embodiment
Shown in figure; On one section tube wall of tracheal intubation 4, be provided with passage 4.1, cover capsule 5 is set with overcoat capsule 6 in outside the tracheal intubation at passage position, being set with outside interior cover capsule; On air injection pipe 3, be connected with vent valve 2.2, gas injection capsule 2 and gas injection valve 2.1 in turn; Be provided with gas injection port 1 on gas injection valve top, air injection pipe is passed anti-again trachea cannula wall behind the tracheal intubation wall, and its gas outlet 3.1 communicates with space between interior cover capsule and the overcoat capsule.
In use, tracheal intubation is inserted in the person's windpipe.
The use of this utility model:
1, is inserted in the person's windpipe from human oral cavity, utilizes it to reach the ventilation purpose.
2, insert from human body neck cervical region tracheotomy mouth, utilize it to reach the ventilation purpose.
After carrying out the person's windpipe intubate, at first in the overcoat capsule, inject a certain amount of gas through gas injection valve and air bag and air injection pipe, make overcoat capsule inflation, the overcoat capsule is closely contacted with the person's windpipe inwall, thus the space between sealing intubate and the person's windpipe.When the gas in the overcoat capsule reaches certain pressure, open vent valve, emit unnecessary gas in the cover capsule; Air pressure and atmospheric pressure in the cover capsule are equal to, at this moment, in venting process; Increasing of airway pressure can act directly on the interior cover capsule, and the cover bag pressure contracts in can making, and produces the force value that is equal to airway pressure; This pressure can make and produce same pressure in the overcoat capsule, makes it closely to contact with inner surface of trachea, prevents the generation of gas leak phenomenon.Interior overcoat intraluminal pressure source relies on the airway pressure that produces in the venting process fully, and the suitable pressure of the automatic maintenance of overcoat capsule makes between intubate and the person's windpipe and reaches closed state in making, and is unlikely to cause the damage of person's windpipe again.
This utility model is compared superior part with traditional tracheal intubation:
1, before tracheal intubation is inserted person's windpipe, because overcoat capsule and interior cover capsule are contraction state, can be inserted into easily in the person's windpipe, be beneficial to the smooth insertion of tracheal intubation; After tracheal intubation reaches the precalculated position, through gas injection in air injection pipe, this gas inflation overcoat capsule; Overcoat capsule outer wall is closely contacted with inner surface of trachea, open the vent valve pressure release afterwards, make the pressure in the overcoat capsule be equal to atmospheric pressure; This moment, the overcoat capsule closely contacted with inner surface of trachea, but did not have pressure, closed vent valve then; With shape and the air-tight state of keeping the overcoat capsule, at this moment carry out mechanical ventilation, by the passage that is arranged on the tracheal intubation wall gas in the human airway is squeezed into interior cover capsule; Interior cover capsule pushes the overcoat capsule again, and overcoat capsule outer wall is contacted with inner surface of trachea, and gas outwards flows out in the shutoff trachea.In whole venting process, the overcoat capsule equates with airway pressure with the pressure of tunica mucosa tracheae junction always, and changes with the variation of airway pressure.The cover capsule that has not only fundamentally solved traditional tracheal intubation continues the drawback of compressing tunica mucosa tracheae for a long time, has also solved the part airway pressure simultaneously and change the drawback that patient greatly leaks air when increasing airway pressure.Patient safety is comfortable.
2, for the patient of indivedual reservation autonomous respirations, in the autonomous respiration process, owing to negative pressure in the air flue can occur; In order to prevent the generation of reflux erroneous aspiration; As long as between interior overcoat capsule, inject little of gas, make the interior pressure of overcoat capsule greater than intake negative-pressure, will finely address this problem; At this moment, the same effect of interior overcoat capsule and conventional sleeve capsule performance.
3, when needs are pulled out tracheal intubation, need not emit the gas in the cover capsule, only open vent valve; To overlap capsule and atmosphere, in the process of tube drawing, owing to retain certain gas in the cover capsule; Can preferably the secretions of overcoat capsule upper end be taken out of, if be obstructed, because cover capsule and atmosphere opening at tracheal stenosis places such as glottises; Gas can overflow automatically, overcoat capsule diameter is reduced, thereby extract tracheal intubation smoothly.
