Example (b): a novel device for ventilation and aspiration-proof gastroscopy is shown in figures 1 to 3 and comprises a protective sheet 1, elastic bands 2 are connected between two sides of the protective sheet 1, through holes 3 are formed in the protective sheet 1, and biting pipes 4 are communicated with the through holes 3 in the back of the protective sheet 1. Sting and wearing to be equipped with breather hose 5 in the pipe 4, breather hose 5 can be followed and sting pipe 4 removal, and the outside aeration equipment of connection can be dismantled to 5 head ends of breather hose, and 5 end covers of breather hose are equipped with gasbag cover 6, and 6 backs of gasbag cover are concave to be equipped with and to step down passageway 13, and 6 intercommunications of gasbag cover have 7 one ends of aerifing the hose, and 7 other ends of aerifing the hose extend to the positive outside aeration equipment of dismantling of protection sheet 1 through stinging pipe 4 and through-hole 3.

When the device is used, a patient lies on the side or on the back, firstly the ventilation hose 5 moves towards the outside of the through hole 3 along the biting tube 4, then the biting tube 4 extends into the oral cavity of the patient and is bitten by the teeth of the patient, the protective sheet 1 is attached to the mouth of the patient, the elastic band 2 is worn on the head of the patient to fix the oral cavity bite block, and finally the gastroscope tube 12 extends into the esophagus 14 of the patient from the through hole 3 for examination. As shown in fig. 4, when the patient has poor breathing, the ventilation hose 5 moves along the bite tube 4 into the through hole 3 and extends to the position below the glottis 15 for ventilation, and the abdication channel 13 on the back of the air bag cover 6 is used for accommodating the gastroscope tube 12. After the tail end of the ventilation hose 5 extends to the position below the glottis 15, the air bag cover 6 is inflated to enable the air bag cover to be expanded and to be in fit contact with the pharyngeal cavity tissue tube wall and the esophagus 14 opening below the glottis 15, the tail end of the ventilation hose 5 is positioned in the air bag cover 6 and cannot be in contact with the pharyngeal cavity tissue tube wall, the pharyngeal cavity mucosa is prevented from being damaged by the tail end of the ventilation hose 5, the air bag cover 6 seals the pharyngeal cavity and the esophagus 14 to protect the trachea 16, and the phenomenon that the esophagus flows back and is sucked into the trachea 16 by mistake is avoided.

Further, in order to movably adjust the position of the ventilation hose 5 to facilitate the extension of the ventilation hose 5 below the glottis 15 and the insertion of the gastroscope tube 12 into the esophagus 14, the ventilation hose 5 is movable left and right with respect to the through-hole 3. Specifically, the ventilation hose 5 is arranged in such a manner that a sliding groove 8 is formed in the upper side of the through hole 3 in the front surface of the protection sheet 1, a sliding block 9 is movably accommodated in the sliding groove 8, an upward clamping ring 11 extending out of the sliding groove 8 is arranged on the sliding block 9, and the clamping ring 11 is sleeved outside the ventilation hose 5. The structure of the clamping ring 11 can be selected to be composed of two clamping arc edges, one ends of the two clamping arc edges are respectively hinged with the sliding block 9, and the other ends of the two clamping arc edges are connected through screws and nuts. Loosening the nut, enabling the two clamping arc edges to rotate oppositely, and loosening the air hose 5 to enable the air hose 5 to move along the clamping ring 11 and the bite tube 4; the nut is tightened and the two gripping arcs grip the breather hose 5 so that it cannot move along the gripping ring 11 and the bite tube 4.

When the gastroscope tube 12 is inserted, the clamping ring 11 is unscrewed, the ventilation hose 5 is moved to the outside of the through hole 3 along the bite tube 4, then the clamping ring 11 is screwed to fix the ventilation hose 5, then the clamping ring 11 is moved through the slide block 9 to move the ventilation hose 5 to the side of the through hole 3, and more space of the through hole 3 is exposed so as to facilitate the insertion operation of the gastroscope tube 12; when breathing is unsmooth after gastroscope tube 12 inserts and needs to assist the ventilation, remove the clamping ring 11 through slider 9 and remove 5 gastroscope tubes 12 tops of ventilation hose, then unscrew clamping ring 11 and move ventilation hose 5 along stinging pipe 4 to through-hole 3 and extend to behind 15 below departments of glottis ventilate and screw up clamping ring 11 again and fix ventilation hose 5.

Further, the air hose 5 may be connected at its head end to an elbow fitting 10 to facilitate connection to external air venting equipment. The end of the inflation hose 7 which is not connected with the airbag cover 6 extends to the front surface of the protective sheet 1 through the bite tube 4 and the clamping ring 11, and the outer wall of the inflation hose 7 can be connected with the outer wall of the ventilation hose 5 so as to avoid the collapse of the inflation hose 7 to influence the intubation operation of the ventilation hose 5.

Parts not described in the above modes can be realized by adopting or referring to the prior art.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments thereof. To the utility model belongs to the technical field of the ordinary skilled person say, do not deviate from the utility model discloses a other embodiments that reach under the technical scheme all should be contained the utility model discloses a within the scope of protection.
