The gastroscopy device comprises a checking device body and an isolated esophagus ventilation device; the inspection device body is provided with a probe which can penetrate through the inside of the second pipeline. The isolated esophagus ventilation device and the gastroscopy device can prevent substances in the stomach from flowing back through the esophagus, and further prevent the substances from entering the trachea and threatening the life health of people.
In actual use, however, the applicant has found that the connection of the second conduit is very inconvenient as the connection point is located below the mask. And the patient can be nervous during use, causing a bite on the second conduit, resulting in damage to the second conduit.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides an endoscope is with preventing stinging esophagus trachea and keeping apart ventilation unit utilizes the inspection mouthpiece to extend into the patient intraoral confession patient and tightly stings, avoids the patient to sting the inspection tube.
In order to solve the technical problems, the technical scheme of the utility model is that the anti-biting esophagus and trachea isolating and ventilating device for the endoscope comprises a face mask, wherein a breathing joint is arranged at the position corresponding to the nose on the face mask, and an inspection interface tube is arranged at the position corresponding to the mouth on the face mask; the inspection mouthpiece may extend through the mask into the patient's mouth; the inspection tube penetrates from the front face of the mask to the back face of the mask through the inspection interface tube; the front end of the device is provided with a collapsible and expandable plugging part.
As an improvement, the inspection mouthpiece is made of PVC. PVC is nontoxic and has certain strength to protect the inspection tube from being bitten.
As a further improvement, the total length of the inspection mouthpiece is 3-4 cm, and the length of the part extending out of the back face of the mask is 2.5-3.5 cm.
As another further improvement, a cover body is arranged at one end of the inspection mouthpiece, which is positioned on the front surface of the mask, and the cover body is connected with the inspection mouthpiece by a pull rope. When not in use, the inspection mouthpiece is closed.
As an improvement, the rear end of the inspection tube is provided with an expansion section, and the diameter of the expansion section is larger than the inner diameter of the inspection interface tube. Avoid the inspection pipe wholly to wear out from the inspection interface tube.
As an improvement, the plugging component is an air bag, and the rear end of the inspection tube is provided with an inflation joint for inflating the air bag; the inflation connector is connected with the air bag by a conduit.
As an improvement, the part of the face mask corresponding to the nose is provided with a bulge, so that the breathing joint and the inspection mouthpiece are not on the same vertical surface. The breathing joint and the inspection mouthpiece are prevented from interfering with each other.
The utility model discloses an useful part lies in: the anti-biting esophagus and trachea isolating and ventilating device with the structure for the endoscope utilizes the plugging component to plug the esophagus, so that food in the esophagus is prevented from flowing back to the air inlet pipe. The inspection mouthpiece extends into the patient's mouth for the patient to bite on, firstly to protect the inspection tube from being bitten, and secondly to secure the mask.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.
As shown in fig. 1-3, the present invention comprises a face mask 1, a breathing joint 2 is arranged on the face mask 1 at a position corresponding to the nose, and an inspection mouthpiece 3 is arranged on the face mask 1 at a position corresponding to the mouth; the examination interface 3 tube may extend through the mask into the patient's mouth; the part of the face mask 1 corresponding to the nose is provided with a bulge, so that the breathing joint 2 and the inspection mouthpiece 3 are not on the same vertical surface. The mask also comprises an inspection tube 4, wherein the inspection tube 4 penetrates from the front surface of the mask 1 to the back surface of the mask through an inspection mouthpiece 3; the front end of the device is provided with a collapsible and expandable plugging part. Specifically, the plugging component is an air bag 5, and an inflation joint 6 for inflating the air bag 5 is arranged at the rear end of the inspection tube 4; the inflation connector 6 is connected to the balloon 5 by a catheter.
The inspection mouthpiece 3 is made of PVC, the total length of the inspection mouthpiece is 3-4 cm, and the length of the part extending out of the back surface of the face mask 1 is 2.5-3.5 cm.
