Patient self-control sedative target control infusion system based on anesthesia depth monitoring

Abstract

The invention discloses a patient self-control sedative target control infusion system based on the anesthesia depth monitoring. The infusion system comprises the four modules of a central processor control module, a BIS sedation depth and vital sign monitoring feedback module, an output request module, and an output execution module. According to the infusion system, the target controlled infusion is used as the mode of the self-controlled dosing for a patient, the target controlled infusion is a therapeutic scheme calculated based on the group drug generation-medicine efficacy power theory by a computer, and blood plasma/effect compartment medicine concentration is used as the target control objective, the target controlled infusion can be rapidly achieved or modulated, the stability and a certain degree of safety of the sedative level can be guaranteed, and the BIS sedation depth monitoring system is used to monitor the sedation depth of the patient, when combined with the vital sign indicator, the clinical safety is increased to a greater extent.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a patient-controlled sedation target-controlled infusion system based on anesthesia depth monitoring. Background technique [0002] In clinical work, when patients undergo endoscopic examination or undergo surgery under nerve block and spinal canal anesthesia, they often have different degrees of tension and anxiety. In order to eliminate this negative emotion, anesthesiologists generally give patients a certain dose However, insufficient or excessive sedation will inevitably occur, which cannot meet the patient's sedative needs or cause adverse consequences. [0003] Patient controlled sedation (PCS, patient controlled sedation) refers to a sedation method in which the patient decides the dosage of sedative drugs by himself to achieve a satisfactory sedative effect when he feels anxious. In the past, patient-controlled sedation was achieved by setting the loading dose...

Problems solved by technology

In the past, patient-controlled sedation was achieved by setting the loading dose, background infusion, single dose, and lock-in time. However, due to the large differences in the response of patients to se...
