The invention provides a coronary heart disease electrocardiogram screening system based on a residual neural network, and the system comprises an electrocardiosignal processing module which is used for extracting electrocardiosignals generated by an electrocardiograph, carrying out the multi-layer decomposition and noise reduction of the electrocardiosignals through employing a symlets4 wavelet, searching the position of an R wave in electrocardiosignal sequence data converted from the electrocardiosignals, and carrying out the heart beat segmentation based on the position of the R wave; a depth feature extraction module which is used for performing translation and scaling on the data processed by the electrocardiosignal processing module to enhance the data, and extracting the depth features of the twelve-lead electrocardiogram by using a ResneXt50 network comprising an extrusion and excitation network module; and a tree model prediction module which is used for combining the depth features extracted by the depth feature extraction module with electrocardiograph data, and inputting the trained XGBoost model to obtain the prediction probability of the coronary heart disease electrocardio features in the electrocardiogram. The system is low in installation and use cost, can achieve automatic screening, is higher in accuracy compared with diagnosis of an electrocardiograph, can reduce misjudgment or missed judgment, and reduces the workload of doctors.

The invention discloses a sample automatic feeder of a full automatic fecal occult blood analyzer. The sample automatic feeder consists of a driving mechanism, a bar code scanning mechanism and a retaining tube mechanism, all of which are arranged on a base plate, wherein the driving mechanism consists of a motor, a synchronous belt and a sample tube frame, a transmission shaft of the motor is connected with a rotary shaft of the sample tube frame through the synchronous belt, the motor drives the sample tube frame to rotate through the synchronous belt, the bar code scanning mechanism consists of a bar code scanner and a support, the support is arranged on the base plate, the retaining tube mechanism consists of a retaining rod, a pull rod, an electromagnet and a tension spring, the retaining rod and the pull rod are connected by a pull rod shaft, and the pull rod drives the retaining rod to rotate through the pull rod shaft. The sample automatic feeder of the full automatic fecal occult blood analyzer, disclosed by the invention, has the beneficial effects of simple structure, convenience for using, stability in mechanical operation and lower installation use cost.
