Intelligent anesthesia system based on EEG-NIRS

The invention discloses an intelligent anesthesia system based on EEG-NIRS. The intelligent anesthesia system based on EEG-NIRS includes a head-mounted signal acquisition module, an anesthesia automatic control module and a data storage module, wherein the head-mounted signal acquisition module comprises a near-infrared light source driving part, an acquisition part, and a control and WIFI communication part, synchronously collects EEG signals and NIRS signals, and transmits the pre-processed EEG and NIRS signals to the anesthesia automatic control module through WIFI communication; the automatic anesthesia control module has functions of dynamic monitoring of anesthesia index, calculation of the required dose and injection speed for a patient through a feedback controller, deep neural network optimization, multi-channel anesthetic injection, etc; and the data storage module can dynamically record the anesthesia data and key nodes, and upload the anesthesia data and key nodes to a server. The intelligent anesthesia system based on EEG-NIRS collects EEG and NIRS signals at the same time, dynamically monitors sedation, analgesia and muscle relaxation of intraoperative patients, accurately controls the infusion rate and infusion volume of anesthetic agents, greatly improves the utilization rate of medical resources, and reduces the use-cost of medical equipment.

Closed loop muscle relaxation iatrical effect monitoring and injecting method and closed loop muscle relaxation injecting device

InactiveCN101816576AReal-time monitoring of muscle relaxationAutomatic drug deliverySurgeryVaccination/ovulation diagnosticsHuman bodyClosed loop
The invention discloses a closed loop muscle relaxation iatrical effect monitoring and injecting method and a closed loop muscle relaxation injecting device. The method comprises the specific steps of: acquiring muscle myoelectricity feedback actions of a patient through an independently developed muscle relaxation monitoring piezoelectric inductor and operating to obtain a muscle relaxation monitoring data TOF (turnover of frequency) value; and controlling a stepper motor to operate at a specified speed so as to push an injector to administrate medicine at a set speed by using the TOF value as a feedback data base and by a microprocessor by combining a built-in muscle relaxation administration method. The scheme can monitor the muscle relaxation state of a patient in real time, objectively reflect the true iatrical effect condition of the muscle relaxant in the human body and display the TOF value of a muscle relaxation feedback value, and meanwhile, an injection system can automatically administrate the muscle relaxant in the whole course according to the TOF value. Moreover, artificial interventions are not needed, and the automatic administrated dosage and the method are obtained through a large quantity of population parameters. The invention ends the times of fuzzy muscle relaxant administration and can scientifically improve the controllability of the muscle relaxant, avoid medicine deficiency or excess and improve the operation quality.

Multifunctional anesthesia monitor

The invention discloses a multifunctional anesthesia monitor including a housing. A display screen is arranged on the upper part of the front side of the housing. An operation press key is arranged on the housing below the display screen. A port is arranged in the front end face of the housing. An alarm and an indicating lamp are arranged at the left side of the upper part of the housing. A light source probe and a temperature sensor are arranged on the left side face of the housing. A brain electricity function monitoring device and an electrocardiogram lead wire are arranged at the right side of the housing. The input terminal of the light source probe is connected with the output terminal of a time sequence control module electrically. The input terminal of the time sequence control module is connected with the output terminal of the single-chip microprocessor electrically. According to the invention, regular monitoring, depth of anesthesia monitoring and muscle relaxation monitoring required by modern anesthesia are implemented by using the multifunctional anesthesia monitor. Besides, the multifunctional anesthesia monitor integrates brain electricity monitoring and a heart rate variability value and a blood pressure fluctuating value, and can send alarm timely when the fluctuation of a monitoring value of a patient during the operation is too large. The analysis is comprehensive and the obtained data is more comprehensive and accurate, the safety of a surgical patient in the stage of narcosis is ensured well.
