The utility model provides a kind of infant anesthesia aromatic mask, specifically relates to medical instrument technical field.A kind of infant anesthesia aromatic mask, including cover body, connection port is provided on cover body outside, the one-way valve is provided at cover body bottom, aromatic device is provided at cover body upper portion, aromatic device includes transparent cover, gauze and filter screen, gauze is fixedly arranged on filter screen upper portion, transparent cover is fixedly connected with bottom filter screen, movable setting has condensation pearl in transparent cover, condensation pearl is sealed and wrapped with edible essence liquid.The utility model has the beneficial effect that: the concept of aromatherapy is applied to pediatric anesthesia mask, which helps to relieve the nervous anxiety of children during anesthesia induction, improves the anesthesia induction cooperation degree, and presses the transparent cover when using, the condensation pearl in the transparent cover is broken under pressure, the edible essence in the interior flows to the gauze, the fragrance is dispersed to the medical mask through the filter screen, during anesthesia induction, anesthesiologist covers the irritating smell of inhaled anesthetic by using aromatic mask.

This application relates to the field of surgical diagnostic technology, specifically to a system for adjusting the ratio of intravenous and inhaled anesthetic drugs based on EEG trend-guided analysis. The system generates a standardized sequence set through data acquisition and preprocessing; an association feature construction module extracts association features between drug ratios and EEG trends based on time lag relationships; an influence strength coefficient calculation module combines the ratio structure entropy and EEG fluctuation coefficients to generate an EEG influence strength coefficient; a sensitivity judgment module calculates sensitivity features based on EEG intervals of patients with similar physical signs, combined with real-time fluctuations and influence coefficients; a parameter dynamic adjustment module dynamically optimizes the EEG analysis intervals and trend weights accordingly; and a ratio recommendation generation module generates multiple drug ratio options with expected EEG changes for selection. This system effectively overcomes the shortcomings of static thresholds in adapting to individual differences and intraoperative fluctuations, significantly improving the accuracy of drug ratio recommendations.

The application provides a closed oxygen supply ventilation device and an oxygen supply system, and relates to the technical field of oxygen supply. The closed oxygen supply ventilation device comprises an oxygen supply pipeline and a sealing assembly. The oxygen supply pipeline is used for cooperating with a patient and can provide oxygen for the patient through the nasal cavity of the patient. The sealing assembly comprises a nasal plug and a connecting piece. The connecting piece is connected to the nasal plug and the oxygen supply pipeline. The nasal plug is used for closing the nasal cavity of the patient without the oxygen supply pipeline. The device can continuously and effectively ensure the air tightness of the nasal cavity position of the patient during operation, is not easy to leak at the nasal cavity position, can provide positive pressure ventilation, and is not easy to leak and cause environmental pollution in the operating room when inhaling anesthetic drugs.
