  • Publication number: 20220330845
    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.
