Ether anesthesia system for laboratory animal and operating method of system

Abstract

The invention belongs to the technical field of anesthesia, and discloses an ether anesthesia system for a laboratory animal and an operating method of the system. The ether anesthesia system for thelaboratory animal comprises a video monitoring module, an electroencephalogram collecting module, a central control module, an electroencephalogram processing module, a metering module, an oxygen supply module, an anesthesia module, a special database module and a display module. Through the electroencephalogram processing module, a self-adaptation fuzzy logic reasoning algorithm is adopted, dataof low-frequency waves, high-frequency waves and BFI in different anesthesia states is trained, and the method has a great resolution capability; the method can automatically display different anesthesia depths, and other nonlinear interference is avoided; meanwhile, through the metering module, the dosage of gaseous anaesthetic in the whole anesthesia process can be precisely calculated, errors caused by manual calculation are avoided, and the accuracy and precision of the dosage calculation result of the liquid anaesthetic are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of anesthesia, in particular to an ether anesthesia system for experimental animals and an operating method thereof. Background technique [0002] Drugs or other methods for anesthesia temporarily deprive the patient of sensation in whole or in part, so as to achieve painless surgical treatment; mainly include general anesthesia and local anesthesia; general anesthesia refers to the administration of anesthetics through inhalation, intravenous, intramuscular injection or rectal perfusion Entering the body, the central nervous system is inhibited, resulting in the loss of consciousness of the patient and the process of feeling no pain in the whole body. This method of anesthesia is commonly known as the "asleep state", which is characterized by the loss of consciousness of the patient, relaxation of the muscles of the whole body, and no pain. The most commonly used method of general anesthesia is endotrachea...

AI Technical Summary

Problems solved by technology

[0004] The existing experimental animal ether anesthesia system to collect animal EEG signals is susceptible to interference from environmental electromagnetic waves, resulting in large data errors and affecting the normal anesthesia; at the same time, because the concentration of anesthesia gas is affected by the gas flow rate, the actual concentration during low micro-flow anesthesia It often deviates from the set concentration of the anesthesia evaporator, so the conclusion of manual calculation often has a large error

[0005] The existing technology cannot effectively realize the real-time monitoring of the ether anesthesia process of experimental animals, cannot effectively grasp the whole process of experimental animals receiving ether anesthesia, cannot understand the state of anesthesia, and is not conducive to recording all reaction states and effects of experimental animals during anesthesia , affecting or delaying later work; in the prior art, it is impossible to accurately measure the dosage of drunk drugs, and it is impossible to control the anesthesia effect and degree of anesthesia in experimental animals, thus reducing the safety of anesthesia in experimental animals; in the prior art, anesthesia monitoring cannot be effectively guaranteed The clear display of video images is not conducive to the user's observation, summary and analysis of the anesthesia process in the later stage, which greatly reduces work efficiency and wastes manpower, material resources and time
