(III) advantageous effects

Compared with the prior art, the invention provides a double-balloon trachea cannula, which has the following beneficial effects:

1. this two gasbag trachea cannula, through after gasbag an and user's gasbag laminating, continue to inject gas in the gasbag an, at this moment unnecessary gas will drive the movable plate rebound, thereby drive and remove the post rebound, thereby insert the inner ring of annular gasbag, just so unnecessary gas just can get into the air channel, again from the gas outlet get into in the gasbag b, after stopping injecting gas, annular gasbag b's elasticity just can be with removing the post rebound normal position downwards, thereby prevent that too big damage of gasbag a inflation user's trachea strength to the user's trachea, the too much gas that injects into in to gasbag a of medical personnel that just can avoid the inspection not enough leads to user's trachea damage, thereby can make things convenient for those experience not enough to use according to the medical personnel that the patient's air flue size accuracy injects into suitable gas.

2. This double-balloon trachea cannula, it is little that gas in the gasbag a leads to gasbag a gas because the tubule does not seal well or other reasons through gasbag a, when unable and user's endotracheal wall laminating, gas in the gasbag b will drive the baffle and move down, thereby gas in the gasbag b just can get into in gasbag a through the connecting pipe, just so can be to supplementary gas in the gasbag a, thereby keep gasbag a can with user's endotracheal wall laminating, can prevent like this that the device from leaking unable support and block up patient's trachea because of gasbag a's gas accident in the use.

3. This two gasbag trachea cannula, through inject gaseous back in the gasbag b, gaseous in the gasbag b will exert pressure to the anther sac because of gasbag b's toughness to can help the medicine in the anther sac to lead to the inslot entering conduit through the annular, thereby improve out the medicine effect.

4. This two gasbag trachea cannula puts into the anther sac through the medicine that will use in user's trachea, and the medicine will lead to the groove through the annular, gets into in the pipe, thereby when making the air flow in the pipe help the user breathe through external device, gaseous will drive the medicine and get into user's trachea to can be directly act on the medicine in user's trachea, can improve the speed that takes effect of medicine like this.

5. This two gasbag trachea cannula, in getting into the pipe from four medicine mouths through the medicine, flowing through air in the pipe, just can drive the rotating vane and rotate to can break up liquid medicine, the medicine will demonstrate vaporificly like this, thereby make things convenient for more that the air brings the medicine into in the user's trachea, can help the even effect of medicine on user's endotracheal wall simultaneously, thereby increase the availability factor of medicine.

6. This double-balloon trachea cannula through two stabilizing ring and two annular spouts, can keep the stability of activity ring to can keep the stability when rotatory ring rotation through two connecting strips, thereby can keep device steady operation.

7. This double-balloon trachea cannula, hide the post through initial shift ring with four medicine mouths, up-movement is followed to gas in the conduit, just can drive rotatory ring rotation through the revolving leaf, thereby can drive the slip ring rotation through two connecting strips, just so can drive the slip ring rebound, just so can spill out the medicine mouth, the medicine just can get into in the conduit like this, thereby can be along with in the air admission user trachea of upflow, when gas in the conduit is from last down-moving, will drive the rotation of revolving leaf to opposite direction, thereby can drive the slip ring through revolving tube and two connecting strips and slip ring and move down, thereby shelter from the medicine mouth, can prevent like this that the medicine from along with air leakage to the external world, thereby avoid the loss of medicine.

8. This double-balloon trachea cannula, when the gas is insufficient in gasbag b can't exert pressure to the anther sac, the ascending power of pressure spring can be exerted to the promotion ring to can make the promotion ring exert pressure to the anther sac, just so can assist the anther sac to go out the medicine.
