Example 1

Referring to fig. 1-2, a painless gastroscope ventilation device comprises a ventilation cover body 1 and an occlusion body, wherein the ventilation cover body 1 is fixed at the upper end of the occlusion body, a first fixing column 2 is arranged on the ventilation cover body 1, two fixing columns 2 are arranged on the first fixing column, a second fixing column 3 is arranged on the occlusion body, and four fixing columns 3 are arranged on the second fixing column. The fixing devices are arranged on the outer sides of the ventilating cover body 1 and the outer side of the meshing body flange 10 and are connected with the first fixing column 2 and the second fixing column 3, and the fixing device is firmly fixed behind the ear. The ventilation mask body 1 is in a triangular pyramid shape, and the bottom of the ventilation mask body is matched with the outer edge of the nose. The bottom of the ventilation mask body 1 is provided with a nasion dent, which is convenient for the mask body to be tightly jointed with the skin of the nasion. The bottom of the ventilation mask body 1 is provided with two cheekbone depressions, which is convenient for the mask body to be tightly jointed with the skin of the cheekbone parts at two sides. The upper jaw bone depression is designed at the bottom of the ventilation cover body 1, so that the cover body can be tightly attached to the skin of the nasal labial sulcus conveniently. The ventilation mask body 1 is provided with an inflation inlet 4 and a breathing circuit interface 5, a breathing monitoring channel 7 with a sealing plug 6 is arranged on the ventilation mask body 1 and between the inflation inlet 4 and the breathing circuit interface 5, and a breathing frequency monitoring device corresponding to the breathing monitoring channel 7 can be placed into the breathing monitoring channel 7 after the breathing monitoring channel 7 is opened for monitoring the breathing frequency of a patient.

The occlusion body comprises an arc-shaped hard shell 8 and an occlusion column 9, and the arc-shaped hard shell 8 and the occlusion column 9 are of an integrally formed structure. Flanges 10 are respectively arranged at two ends of the arc-shaped hard shell body 8, and hanging holes are formed in the flanges 10. The center of the arc-shaped hard shell 8 is provided with a mounting hole, the occlusion column 9 is fixed in the mounting hole, a gastroscope channel 12 is arranged in the occlusion column 9, and the gastroscope channel 12 is used for a gastroscope to pass through. A sealing device is arranged in the gastroscope channel 12 and seals between the outer wall of the gastroscope and the inner wall of the gastroscope channel 12. One end of the arc-shaped hard shell body 8 facing the face of the patient is provided with a sealing gasket 13.
