AI Technical Summary
Technical Problem
Existing pressure masks have poor sealing properties when not undergoing gastroscopy and cannot effectively support the patient's respiratory function.
Method used
A pressure mask with an iris mechanism was designed to open the examination port and hold the endoscope tightly during gastroscopy to prevent gas from escaping; and to completely close the examination port when not in use to prevent oxygen leakage and ensure a tight seal.
Benefits of technology
During gastroscopy, it effectively supports the patient's respiratory function, prevents droplets and gas from escaping, reduces the risk of environmental pollution, and minimizes oxygen leakage and ensures a tight seal when not in use.

Abstract
The utility model discloses a kind of pressurized face masks, when gastroscopy is carried out, face mask main body cover is set in the face area of patient, then oxygen supply structure is connected oxygen supply equipment, to effectively support the respiratory function of patient, at this time, iris mechanism opens examination port, and after gastroscopy enters examination port, examination port is reduced, to hold gastroscopy, ensure that gastroscopy is successfully completed;Before or after gastroscopy, oxygen supply structure is connected oxygen supply equipment, to support the respiratory function of patient, at this time, iris mechanism completely seals examination port, to prevent oxygen from examination port to leak out to the greatest extent, guarantee the sealing performance of pressurized face mask, realize effectively support the respiratory function of patient;The scheme forms the examination port for gastroscopy to enter and exit by iris mechanism, and can realize the complete closure to examination port, relative to prior art, the sealing of pressurized face mask is guaranteed, can effectively support the respiratory function of patient, strong practicality, suitable for extensive promotion and application.
