The application provides a cerebral apoplexy postoperative sign monitoring system, which is fused with a nerve motor function evaluation wristband and a head-mounted brain electrical impedance dynamic imaging device, and breaks through the blind area of postoperative monitoring. The wristband device collects upper limb electromyographic signals and joint motion mechanics parameters through a microneedle electrode array and a distributed piezoresistive sensor, drives a neural network to output a standardized motor score based on time-frequency domain features containing electromyography, joint angle, trajectory smoothness and grip force change rate, and is related to a clinical Fugl-Meyer scale; the imaging device adopts a multi-ring electrode array and an improved D-bar algorithm to reconstruct a brain electrical conductivity distribution map, constructs a multi-level decision tree early warning model by extracting impedance change rate Delta Z, spatial gradient entropy SGE and hemisphere asymmetry Asym, and realizes brain edema detection. Through multi-modal data fusion and minute-level response, the system solves the fragmentation problem of postoperative monitoring and provides precise decision support for cerebral apoplexy rehabilitation.

The utility model discloses a kind of extracorporeal circulation systems, it is related to medical instrument technical field.Extracorporeal circulation system includes the inflow pipe, handle and outflow pipe connected in turn, inflow pipe is used to connect carotid artery, outflow pipe is used to connect vein;Handle includes shell and the flow through switch, flow through regulator and blood filter being set in shell.In application when inflow pipe is connected into carotid artery, outflow pipe is connected into vein, high-pressure arterial blood flow and low-pressure venous blood flow form pressure difference, make the blood flow of carotid artery reverse flow to vein, establish the blood retrograde passage from carotid artery to vein, can be opened and closed above-mentioned retrograde passage by flow through switch, utilize flow through regulator to adjust the flow rate and flow of blood flow, and utilize blood filter to intercept thrombus and other accumulations falling in interventional operation, reduce the problem that thrombus and other accumulations enter brain with blood and cause cerebral apoplexy or embolism.
