Problems solved by technology

Since it is an investigation of adverse events, it cannot be guaranteed that patients can truly reflect the situation. According to expert experience, young doctors and primary hospitals know more about the events during anesthesia.

specific Embodiment

[0042] The present invention relates to the manufacture of a set of systems, including data acquisition and transmission terminals, wireless communication terminals, TCI target control systems, fixed terminals, computing and data management terminals, etc. , computer and server analgesia, brain wave feature extraction method and normalized expression of sedation degree.

[0043] Data collection and processing:

[0044] Record EEG signals through scalp electrodes, see figure 1 . The EEG acquisition electrodes were placed 2cm above the center point of the forehead and eyebrows (FZ), above the bilateral eyebrow arches (left FP1, right FP2), and the reference electrodes were placed on the bilateral mastoids (left A1, right A2) .

[0045] The recorded EEG signal is a comprehensive reflection of the electrophysiological activity of nerve cells in the brain, which reflects both cortical EEG and subcortical EEG. The potential of any point on the scalp, whose physical and chemical ...

Abstract

The invention discloses a multi-channel intelligent drug delivery system, which comprises: a data acquisition and transmission terminal, a TCI target control system, a wireless communication terminal,a calculation and data management terminal; The data acquisition and transmission terminal collects a scalp electrode to record an EEG signal; through the decomposition and reconstruction of the brain wave signal, the cortex and subcortical EEG can be extracted, and a two-compartment model of the cortex and subcortex is established for interactive analysis; for the pre-processed brain wave data,a waveform recognition algorithm and a wavelet analysis algorithm are applied to obtain different brain state objective theorem measurement data; A computer controlled drug-delivery technique is characterized by maintaining the drug concentration in the blood by a TCI target control system. The system can realize the analgesia and sedation monitoring during the operation, and summarizes the physiological indicator data of other monitors through a wireless data transmission technology, the concentration of an effect chamber in anesthesia is adjusted within a reasonable range, and the technicalproblem of ideal individual-specific multi-channel anesthesia analgesia and sedation is realized by the TCI technology.

Description

technical field [0001] The invention relates to an operation anesthesia drug delivery system. Background technique [0002] Due to the complexity of the clinical environment, the variability of individual patients and the complexity of the condition, the variability of vital signs, and the suddenness of events during the operation, there are still many anesthesia adverse events in the field of anesthesia. No matter how rich anesthesiologists are, it is inevitable that excessive drug administration will lead to cardiovascular or nerve damage, and insufficient drugs will cause intraoperative awareness. Some experts surveyed 11,101 patients with general anesthesia in 25 domestic university affiliated hospitals and found that the incidence of awareness during operation was 0.41% (Xu L, et al.Acta Anaesthesiol Scand). Calculated by the annual number of operations, about 15,000 people have experienced intraoperative awareness. Since it is an investigation of adverse events, it c...
