Abstract: The present invention relates to the field of biomedical signal processing, specifically, a device and method of implementation for enhancing the accuracy of fetal heart rate acceleration data recognition. The present invention comprises: collecting fetal heart rate data in a pre-configured period so as to obtain a fetal heart rate data sequence, H(n); performing baseline identification on the fetal heart rate sequence, H(n), to obtain a fetal heart rate baseline data sequence, B(n); pre-processing the fetal heart rate data sequence, H(n), to obtain a pre-processed fetal heart rate data sequence, C(n); performing acceleration recognition on the pre-processed fetal heart rate data sequence, C(n), according to pre-configured acceleration determination criteria and the fetal heart rate baseline data sequence, B(n), to obtain acceleration data segments; calculating an acceleration attribute value for each of the acceleration data segments, and outputting each acceleration data segment and the acceleration attribute value calculation result thereof. The technical solution provided by the present invention effectively distinguishes the variations between the accelerations and the baseline, accurately recognizes each acceleration in continuous accelerations, and avoids the situations of the detected number of fetal heart rate data accelerations being lower than the actual number or being mistaken due to current methods, thereby enhancing the accuracy in recognizing fetal heart rate curve accelerations.

Abstract: A detection probe and a fetal monitor. The detection probe comprises a probe body (2) and a mounting structure (1), detachably mounted on the probe body (2) and having a heart rate sensor for heart rate detection, a socket (4) for data transmission, and a lead line (5) for connecting the heart rate sensor and the socket (4) arranged thereon. A variety of functions can be achieved by means of a single detection device and thus the degree of integration is high; moreover, when the heart rate sensor is failed or aged, because the mounting structure (1) can be separated from the probe body (2), it is only necessary to repair and replace a corresponding part, so that the maintenance is convenient and the cost is reduced. Furthermore, the mounting structure (1) can also product the probe body (2) to some extent, and thus the anti-dropping capability of the detection probe is improved.

Abstract: A device and method for improving the identification accuracy of fetal heart rate deceleration. The method includes: collecting fetal heart rate data (101); performing baseline identification on the collected fetal heart rate data (102); preprocessing the collected fetal heart rate data (103); performing deceleration identification on the preprocessed fetal heart rate data according to preset deceleration judgment standards and a fetal heart rate data baseline to obtain a decelerated data segment (104); and calculating a deceleration attribute value of each decelerated data segment (105), and outputting the decelerated data segment and calculation result (106). The present invention can effectively eliminate the baseline variation part by employing methods such as the dynamic threshold area method, continuous wave peak detection and composite deceleration detection and so on, and accurately identify each deceleration and the type thereof, avoiding the defects of the existing method, which easily causes large deceleration identification errors but cannot identify continuous deceleration or eliminate baseline variation and cannot identify composite deceleration and so on. The solution in the present invention is not only suitable for the situation where deceleration occurs independently and is typical deceleration but also is suitable for the situation where continuous deceleration and composite deceleration occur.
