Anesthesia and consciousness depth monitoring system and method

Abstract

The invention discloses an anesthesia and consciousness depth monitoring system and a monitoring method. The system comprises an anesthesia depth sensor and a cerebral blood oxygen saturation sensor which are worn on the head, and a main controller which is connected with the two sensors through cables. Wherein the main controller comprises an electroencephalogram signal acquisition module, an infrared light transceiving module, a central processing unit, a display output module and a user input module; the central processing unit is used for sending a synchronous instruction acquisition signal to the electroencephalogram signal acquisition module and the infrared light transceiving module; receiving the electroencephalogram acquisition data processed by the electroencephalogram signal acquisition module and the cerebral blood oxygen acquisition data processed by the infrared light transceiving module; and the central processing unit performs synchronous data processing on the electroencephalogram acquisition data and the cerebral blood oxygen acquisition data to obtain electroencephalogram and cerebral blood oxygen saturation synchronous data, and displays a numerical value or a trend curve on the display output module. Electroencephalogram and cerebral blood oxygen collection is synchronized, and synchronous collection and analysis and real-time extraction of related indexesare truly achieved.

Description

technical field [0001] The invention relates to the technical field of anesthesia depth monitoring, in particular to an anesthesia and consciousness depth monitoring system and method. Background technique [0002] Anesthesia depth monitoring has always been a concern of anesthesiologists. The depth of anesthesia depends on the balance between the two antagonistic factors of anesthetic dose and surgical stimulation. The optimal depth of anesthesia requires a sufficient amount of anesthetic to maintain unconsciousness without affecting the function of vital organs. The level of depth of general anesthesia needs to be appropriate for the individual patient undergoing surgery. If anesthesia is deeper than necessary to keep the patient unconscious, anesthesia-related complications may increase, such as postoperative nausea, vomiting, and cognitive impairment. If the depth of anesthesia is too shallow, the patient may not be completely unconscious and there is a risk of intrao...

AI Technical Summary

Problems solved by technology

On the one hand, since they are two different systems, their respective times are independent of each other, which will cause the monitored value to not necessarily be the state of the patient at the same time point

In addition, since they are independent systems, it is not convenient for medical workers to combine the data of the two systems for long-term correlation analysis, etc.

In addition, there is another inconvenience that it is difficult to combine these two indicators for real-time joint analysis

[0010] Chinese patent document CN 108113668 discloses an integrated anesthesia depth and cerebral blood oxygen saturation detection sensor, which respectively fix the anesthesia depth sensor and cerebral blood oxygen saturation sensor on the belt, although it solves the problem of successive detection by the two systems The problem is that one detection sensor can be used to measure the depth of anesthesia and cerebral blood oxygen saturation at the same time. Since it is simple to integrate the two sensors together for detection, it only improves the convenience of detection, and it is not realized in data processing. Multi-parameter synchronization, joint analysis and real-time extraction of indicators
