Abstract

The invention discloses a closed loop control device for low blood volume shock liquid resuscitation, comprising a physiological signal acquisition part, an intelligent controller and a display and alarm device, wherein the physiological signal acquisition part is used for acquiring a human body physiological signal; the intelligent controller is used for receiving information acquired by the physiological signal acquisition part and controlling the infusion according to the received information; the display and alarm device is connected with the intelligent controller; and the intelligent controller is connected with a high-flow infusion pump through a connector. The physiological signal acquisition part comprises an oral mucosa PCO2 acquisition unit consisting of a PCO2 sensor and a PCO2 amplifying circuit, anelectrocardial electrocardialacquisition unit consisting of an hemodynamic indexes, microcirculationresuscitation on patients suffered from wound shock, burn shock and other low blood volume shocks, optimizes and adjusts the infusion speed of fluid infusion, and improves the microcirculation perfusion condition and the clinical prognosis of patients.

Description

technical field [0001] The invention relates to a closed-loop control device. In particular, it relates to a fluid resuscitation system for hypovolemic shock that can implement closed-loop fluid resuscitation control for patients with hypovolemic shock such as trauma shock and burn shock by continuously and non-invasively monitoring the patient's hemodynamic indexes, microcirculation and tissue perfusion indexes. Closed loop control device. Background technique [0002] With the increasing frequency of global local wars, natural disasters and terrorist activities, pre-hospital first aid and continuous treatment technology and equipment have become the focus of critical care medicine and related disciplines research, among which research on shock resuscitation theory and technology has received much attention. In recent years, some countries have used modern resuscitation theory, intelligent control technology, artificial intelligence technology and other research results to...
