Fig. 2 is the right TV structure sketch map of the present invention
Among the figure, 1. tracheal intubation, 2. cover capsule, 2.1. umbrella shape wall, the spacing net of 2.2., the spacing mesh of 2.21., 2.3. cover capsule injecting hole, 2.4. air injection pipe, 3. vent valve, 4. air bag, 5. gas injection port, 5.1. gas injection valve.
The specific embodiment
According to the figure, be bonded with the cover capsule 2 of sealing in the periphery of one section tracheal intubation 1, in the tracheal intubation position in cover capsule interval, be provided with cover capsule injecting hole 2.3 and be communicated with air injection pipe 2.4, air injection pipe is stretched out by the tracheal intubation wall and is connected on the vent valve 3, on vent valve, be connected with air bag 4 again by pipeline, be connected with gas injection port 5 on the top of air bag, be provided with gas injection valve 5.1 in it.The front portion of cover capsule is a umbrella shape wall 2.1, is connected with spacing net 2.2 in umbrella shape wall front side, at spacing several spacing mesh 2.21 that is provided with on the net.
Vent valve communicates with atmosphere.
The two ends and the tracheal intubation of cover capsule are bonding, and inflation back cover capsule front end is the umbrella shape shape.
The gas injection valve is a check valve.
Air bag has the effect of buffering air pressure, simultaneously the size of observing gas pressure in the air bag according to its drum, flat degree.
The umbrella shape wall is umbrella shape, when the umbrella shape wall is under pressure, can make cover capsule space compression, thereby increase thrust with inner surface of trachea, play the effect that cover capsule and inner surface of trachea seal, keep at any time between tracheal intubation and the person's windpipe preventing the generation of gas leak phenomenon at the minute-pressure state.
Use of the present invention
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, sleeve bag gas-filling is expanded by gas injection valve and air bag and air injection pipe a certain amount of gas of injection in the cover capsule, the cover capsule is closely contacted with the person's windpipe inwall, thus the space between sealing intubate and the person's windpipe.When the gas of cover in the 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 umbrella shape wall that overlaps capsule, because the setting of spacing net, the cover bag pressure is contracted, produce the force value that is equal to airway pressure, this pressure can make in the cover capsule and produce same pressure, make it closely to contact, prevent the generation of gas leak phenomenon with inner surface of trachea.Cover intraluminal pressure source relies on the airway pressure that produces in the venting process fully, makes the cover capsule keep suitable pressure to make between intubate and the person's windpipe automatically and reaches closed state, is unlikely to cause the damage of person's windpipe again.
The present invention compares superior part with traditional trachea cannula
1, before trachea cannula inserts person's windpipe, air in the cuff is extracted out fully, be close to the trachea cannula tube wall to guarantee cuff, be beneficial to inserting smoothly of trachea cannula, after trachea cannula reaches the precalculated position, in cuff, inject proper amount of gas, open so that cuff fully expands, and make cuff and tunica mucosa tracheae close contact. Then, open vent valve, cuff is communicated with atmosphere, like this, cuff and tunica mucosa tracheae are in bonding state, but cuff does not have pressure to tunica mucosa tracheae, then vent valve cuts out. In venting process, be subjected to the effect of airway pressure, airway pressure increases, and order about the umbrella shape wall and compress to the cuff position, make cuff keep swelling state, produce the pressure that cuff outer wall and tunica mucosa tracheae keep sealing, the pressure that this moment, cuff acted on the tunica mucosa tracheae is equal to airway pressure just, does not therefore have Leakage Gas; During expiration, along with the gradually attenuating of airway pressure, the pressure that acts on umbrella shape wall and the cuff also can lower gradually, and by the gas effect in the cuff, the pressure on the tunica mucosa tracheae is reduced simultaneously, until be zero. In whole venting process, cuff equates with airway pressure with the pressure of tunica mucosa tracheae junction always, and changes with the variation of airway pressure. The cuff that has not only fundamentally solved traditional trachea cannula 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 in cuff, inject a small amount of gas, make the interior pressure of cuff greater than intake negative-pressure, will finely address this problem, at this moment, the same effect of umbrella shape cuff and traditional cuff performance.
3, when the needs extubation, do not need to emit the gas in the cuff, only open vent valve, cuff is communicated with atmosphere, in the process of tube drawing, owing to retain certain gas in the cuff, can preferably the secretion of cuff upper end be taken out of, if be obstructed at tracheostenosis places such as glottises, because cuff and atmosphere opening, gas can overflow automatically, cuff is reduced, thereby extract trachea cannula smoothly.
