Portable anesthesia and operation integrated system

Abstract

The invention belongs to the technical field of anesthesia, and discloses a portable anesthesia and operation integrated system which comprises a physiological data acquisition module, a main control module, an anesthesia module, an anesthesia control module, an anesthetic dosage calculation module, an operation module, a lighting module and a display module. The anesthesia control module collects electroencephalogram analog signals in the anesthesia process of a patient in real time, the electroencephalogram analog signals are converted to extract a physiological feature value system, and judgment is conducted according to the physiological feature value system through the machine model; the working mode of the anaesthesia machine is regulated and controlled according to the judgment result, automation of the process of judging and regulating the anaesthesia machine is achieved, and on the basis that the accuracy of judging the consciousness state and the breathing state of the patient is improved, the real-time performance of regulation and control is guaranteed; the dosage of gaseous anesthetic in the whole anesthesia process can be accurately calculated through the anesthetic dosage calculation module, errors caused by manual calculation are avoided, and the accuracy and precision of a liquid anesthetic dosage calculation result are effectively improved.

Description

Technical field [0001] The present invention belongs to the field of anesthesia technology, in particular to a portable anesthesia and surgical integration system. Background [0002] Currently, anesthesia is a kind of reversible function inhibition of the central nervous system and / or peripheral nervous system produced by drugs or other methods, which is characterized mainly by the loss of sensation, especially pain. General anesthesia refers to the process of inhaling, intravenous, intramuscular injection or rectal perfusion into the body, so that the central nervous system is inhibited, resulting in the patient's consciousness disappearing and there is no pain sensation around the body. This method of anesthesia is often referred to as the "sleeping state", which is characterized by the patient's loss of consciousness, the relaxation of muscles throughout the body, and the inability to experience pain. The most commonly used method of general anesthesia is endotracheal intuba...

Problems solved by technology

[0003] However, the existing portable anesthesia and surgery integrated system adjusts the parameters of the anesthesia machine differently in different situations; Heart rate, respiration and other parameters are used to judge the depth of anesthesia. However, under the influence of drugs such as vasodilators, these judgments will become unreliable, and the state of consciousness and breathing state cannot be fully grasped. Manual adjustment of anesthesia machine parameters has certain Hysteresis, and it cannot be synchronized with the anesthesia breathing work mode required by the patient at that time; at the same time, because the concentration of anesthesia gas is affected by the gas flow rate, the actual concentration often deviates from the set concentration of the anesthesia evaporation tank during low micro-flow anesthesia , so the conclusions of manual calculations often have large errors

[0004] Through the above analysis, the problems and defects of the existing technology are: the existing portable anesthesia and surgery integrated system adjusts the parameters of the anesthesia machine differently under different circumstances; Signs, such as blood pressure, heart rate, breathing and other parameters to judge the depth of anesthesia, however, under the influence of drugs such as vasodilators, these judgments will become unreliable, unable to fully grasp the state of consciousness and breathing, after manual adjustment of anesthesia The parameters of the machine have a certain hysteresis, and it cannot be synchronized with the anesthesia breathing mode required by the patient at that time; at the same time, because the concentration of anesthesia gas is affected by the gas flow, the actual concentration often deviates from the anesthesia concentration during low micro-flow anesthesia. The setting concentration of the evaporation tank, so the conclusion of manual calculation often has a large error
