The utility model provides a kind of detectable carbon dioxide type glottis upper ventilation structure, including gastroscope bite and ventilation catheter, ventilation catheter and gastroscope bite intercommunication, ventilation catheter intercommunication has multifunctional joint, and multifunctional joint is equipped with oxygen interface, multifunctional joint is also intercommunication with CO2 sampling pipe, and oxygen interface and ventilation catheter intercommunication, CO2 sampling pipe is located in ventilation catheter.In, multifunctional joint includes inner tube and outer tube, and ventilation catheter upper end is inserted into the annular space between inner tube and outer tube and is interconnected with outer tube lower end, and inner tube upper end is connected with CO2 sampling interface, and CO2 sampling pipe is inserted from inner tube lower end and is interconnected with CO2 sampling interface.The utility model can realize oxygen supply and carbon dioxide collection simultaneously or in operation by multifunctional joint during gastroscopy, solve the problem of patient hypoxia in current painless gastroscopy diagnosis and treatment, meet the demand of effective monitoring end-tidal carbon dioxide concentration, and ventilation oxygen supply and carbon dioxide detection can be carried out without stopping gastroscopy.

The present application relates to the technical field of medical information technology and clinical risk prediction, in particular to a gastric retention risk prediction system based on a machine learning model and a construction method thereof, the system comprising a data acquisition module, a feature processing module and a risk prediction module, wherein the feature processing module is based on 12 clinical features screened by LASSO regression, and the risk prediction module adopts an extreme gradient boosting model constructed by an SMOTE enhanced training queue to output a gastric retention risk probability value; the present application integrates 12 key features collected by clinical routine, and introduces a SHAP algorithm to realize visualized explanation of the model decision process, thereby providing a precise and interpretable individualized risk assessment tool before gastroscopy.

The utility model discloses a disposable gastroscopy bag which comprises a first packaging bag, a first upper buckling strip is arranged on the upper portion of the opening end of the first packaging bag, a first lower buckling strip is correspondingly arranged on the lower portion of the opening end of the first packaging bag, and the first upper buckling strip is buckled in the first lower buckling strip. According to the disposable gastroscopy bag, the opening of the first packaging bag forms a clamping limiting structure through the first upper clamping buckle strip and the first lower clamping buckle strip, and the air bag and the first packaging bag form a connecting structure through the first mucilage glue, so that the interior of the first packaging bag can be supported through the air bag, and the disposable gastroscopy bag has certain supporting performance; according to the device, the first packaging bag is arranged to prevent the first packaging bag from being damaged by hard materials in the first packaging bag when the first packaging bag is extruded, the fixing belts of the device form a connecting structure through the second mucilage glue, and therefore when the outer side of the first packaging bag is damaged, the sealing structures on the four sides of the first packaging bag can be recovered through the second mucilage glue, and garbage generated during inspection can be recycled in a centralized mode.

This invention relates to the field of medical devices, specifically disclosing a medical defoamer and its preparation method. Existing medical defoamers primarily function to lubricate and eliminate gastrointestinal foam, but often have limited functionality or poor synergistic effects, impacting the clarity of gastroscopy, patient comfort, and operational efficiency. The medical defoamer of this invention comprises, by weight percentage: 1-5% dimethyl silicone oil, 0-1% Span 60, 0-0.5% Span 80, 5-10% Tween 80, 5-10% glycerol, 0.5-1% lidocaine hydrochloride, 0-0.5% potassium sorbate, 0.2-1% mono-fatty acid glycerides, and the remainder being purified water. The formulation uses a compound of dimethyl silicone oils of different viscosities and specific proportions as the core lubricating and defoaming matrix; employs a non-ionic composite emulsification system of Span and Tween to ensure stable emulsification of the oil and water phases; introduces mono-fatty acid glycerides as a physical defoaming aid and system stabilizer; and uses lidocaine hydrochloride to achieve surface anesthesia.

This utility model discloses an anti-dislodgement mouth pad for assisting gastroscopy, belonging to the field of medical mouth pad technology. The anti-dislodgement mouth pad for assisting gastroscopy includes a pad placed on the surface of the patient's mouth. Buckles are symmetrically fixed on both sides of the pad, and mounting grooves are symmetrically formed on both sides of the pad. An elastic rope is threaded through the mounting groove, and multiple strip-shaped grooves are evenly spaced on the elastic rope. The elastic rope is connected to the buckles through the strip-shaped grooves. A mouth ring is installed on the pad, which the patient bites into. A flexible occlusal mechanism to protect the patient's gums is provided on the outside of the mouth ring. A thickened gauze ring is provided on the outside of the mouth ring to improve the comfort of biting for edentulous patients. Furthermore, the mouth pad can be stably and seamlessly connected to the endotracheal tube, preventing the connection from falling off during surgical examination.
