Abstract: An ultrasonic transducer (200) includes: a piezoelectric vibrator assembly (10), an acoustic matching layer (20), a heat sink (30), and an acoustic absorption layer (40). The heat sink (30) comprises a body (31), and a head portion (32) and a tail portion (33). The body (31) has a central axis extending in a direction from the head portion (32) to the tail portion (33). A surface of the tail portion (33) of the heat sink (30) disposed away from the head portion (32) is a first surface (331). The first surface (331) is an oblique surface or a tapered surface. The angle between the first surface (331) and the central axis is an acute angle. The acoustic absorption layer (40) at least covers the first surface (331).

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.
