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 invention provides an operating room anesthetic waste gas treatment device and method, belongs to the technical field of medical instruments, and aims to solve the technical problem that the operating room environment is continuously polluted due to the fact that the anesthetic gas metabolic rate is low and expired gas of a patient contains anesthetic gas. Comprising an air inlet provided with a valve capable of being opened and closed; the temporary storage bin is connected with the gas inlet, is provided with a first pressure regulator and can provide negative pressure to actively inhale waste anesthetic gas or provide positive pressure to actively discharge gas in the bin; the adsorber comprises a filtering section and a containing cavity section which are communicated, the filtering section is communicated with the temporary storage bin, the containing cavity section is provided with a second pressure regulator, the filtering section is provided with anesthetic waste gas adsorption filler, and a gas outlet is formed in the area between the filtering section and the containing cavity section. The technical effects of removing waste anesthetic gas in the operating room and guaranteeing the air quality in the operating room are achieved.

The utility model relates to the technical field of anesthesiology department appliances, and discloses an anaesthetic mask which comprises a mask part, an intubation part and a hanging ring part, the intubation part used for being connected with a gas pipeline is movably inserted into an adjusting socket arranged at the upper end of a mask body, and when the anaesthetic mask is used, the mask body covers the face of a patient through pressing so as to cover the mouth and the nose of the patient; the sealing attaching ring at the lower end of the mask body can improve the sealing performance, when the mask covers the mouth and nose of a patient, the distance between the lower end of the intubation part and the mouth and nose of the patient is shortened by moving downwards to adjust the intubation part, and the patient can conveniently inhale anesthetic medicine in time.

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.

The utility model provides a parallel operation type continuous anesthesia device for mass animal experiments, which relates to the technical field of animal experiment instruments and comprises a box body, at least two through holes are arranged at the front end of the box body, and the through holes are hermetically connected with guide parts through mounting grooves. A variable-diameter contact piece is arranged at one end of the guide piece and used for tightly wrapping the neck of the animal; a guiding cavity and a guiding rope are arranged in an opening in the middle of the flexible cover, and the opening can be tightened by pulling the guiding rope to achieve sealing. By means of the design of'head and body separation ', the head of an experimental animal continuously inhales anesthetic gas in the box body, and limbs are led out of the box body for operation. By means of the structure, synchronous anesthesia and parallel limb operation of a plurality of animals are achieved, experiment efficiency is remarkably improved, anesthesia gas leakage is effectively blocked, continuity and stability of the anesthesia process are guaranteed, and animal stress response and personnel occupational exposure risks are reduced.

The invention discloses a laboratory mouse inhalation type anesthesia treatment device, and belongs to the field of mouse anesthesia equipment.The laboratory mouse inhalation type anesthesia treatment device comprises a base plate, one side of the upper surface of the base plate is fixedly connected with an anesthesia cabin, the outer surface of one side of the anesthesia cabin is fixedly connected with a transition cabin, the two sides of the transition cabin are each provided with a movable door, and the transition cabin communicates with the anesthesia cabin through the movable doors; a feeding mechanism is further arranged on the upper surface of the base plate and penetrates through the transition cabin and the anesthesia cabin, and a non-contact mouse feeding mechanism is arranged on one side of the anesthesia cabin; and the experimental operation platform is arranged on the feeding mechanism. According to the anesthesia cabin, the cabin door is arranged, so that during initial anesthesia, only the cabin door needs to be opened, and a mouse is placed into the anesthesia cabin, the operation is convenient and simple, and the difficult operation of fixing the mouse when the mouse is sober is omitted; leaked anesthetic gas can be well absorbed and purified, so that the safety of an experiment is ensured.

The invention provides a modeling method and application of a simple anaphylactoid purpura animal model. The modeling method comprises the following steps: adaptively feeding SPF rats for 3 days; the hot traditional Chinese medicine is continuously injected into the stomach for 7 days, and 1mL / 100g body mass is injected every day; on the seventh day and the fourteenth day, an abdominal cavity sensitizer is injected to the abdominal cavity of the rat twice; shaving a local area on the back of the rat on the 25th day, performing inhalation anesthesia on the rat, performing warm water local wet compress, and then removing local stubbles by using a scraper; injecting a caudal vein sensitizer into the caudal vein of the rat; and after 30 minutes, intradermal injection of an intradermal sensitizer is carried out, 4-5 points are divided, waiting is carried out for 24 hours, so that the antigen is completely excited, and molding is completed. The hot traditional Chinese medicine comprises the following raw materials: cinnamon, fructus piperis longi and rhizoma zingiberis. The modeling time is shorter, the modeling rate is high, the cost is lower, and blood routine, renal function, immunity and inflammation index detection results and skin and kidney pathological results of model rats are all highly similar to those of simple / blood-heat syndrome anaphylactoid purpura patients.
