Brain electricity monitoring sedation depth close loop control injection pump device

Abstract

The invention relates to a brain electricity monitoring sedation depth close loop control injection pump device. The brain electricity monitoring sedation depth close loop control injection pump device comprises a brain electricity data gathering module and an injection module host machine which are integrated in the same device, wherein the brain electricity data gathering module is used to gather original brain electricity signals of a human body and convert the original brain electricity signals into a quantized data index which can monitor the sedation depth, and the injection module host machine is connected with the brain electricity data gathering module, and used to confirm sedation drug administration parameter information according to the quantized data index and control sedation drug injection doses according to the sedation drug administration parameter information. The brain electricity monitoring sedation depth close loop control injection pump device achieves integration of brain electricity monitoring technology and injection pump technology, uses the brain electricity monitoring sedation depth to perform close loop control, achieves individualized drug administration and accurate drug use, avoids clinic harm generated due to deep or shallow anesthesia or sedation, and avoids negative effects brought to a patient, which are generated due to large or small doses.

Description

technical field [0001] The invention relates to an automatic control device for intravenous injection (or infusion) of anesthesia (sedation) drugs, in particular to a closed-loop control injection pump device for brain electricity monitoring sedation depth, which belongs to the technical field of anesthesiology. Background technique [0002] How to apply sedative drugs more accurately for anesthesia is a problem faced by clinical intravenous anesthesia. In recent years, such as Bispectral Index (BIS), Auditory Evoked Potential Index (AEPindex, AEPI), NCT (Narcotren index anesthesia / EEG consciousness depth monitoring system), anesthesia entropy (EEG Spectral entropy) and CSI (cerebral State Index) can reflect the components of brain consciousness and guide better use of sedative drugs. Monitoring equipment is more and more in clinical application. Doctors manually adjust the dosage of syringe pumps according to EEG indicators. [0003] Because the syringe pump and the monito...

AI Technical Summary

Problems solved by technology

In addition, there are great clinical risks in the application of technology: anesthesia monitors are multi-parameter monitoring devices, not only have the data of EEG bispectral index, but also many other monitoring data, such as: heart rate, blood pressure, pulse oxygen, etc.

The communication interface reserved by the monitor for other designated devices is not a data interface for non-designated third-party devices, and the transmitted data will also be processed differently for different designated devices. The monitor manufacturer will not Guarantee the accuracy of its data on non-designated third-party devices. If these data are received and used as the main basis or indicator for drug administration of the device, errors are likely to occur. Cause medical accidents, because narcotic drugs are extremely harmful drugs, and the risk of overdose is extremely high
