ULTRASONIC PROBE AND ULTRASONIC EXAMINATION DEVICE

PROBLEM TO BE SOLVED: To provide an ultrasonic probe and an ultrasonic examination device with which the degree of change is detected in a contactless state when a distance between the end face of probe holder and the surface of reagent is changed in the case of measurement based on a local water immersion injury searching method, following measurement is appropriately controlled, and further the flow rate of medium can be appropriately managed. SOLUTION: Concerning the ultrasonic probe with which a local water immersion injury search is performed by supplying water from a water supply hose 17, while keeping constant an interval between a reagent 16 and a probe holder 13 by additionally providing the water supply hose 17 for supplying a medium (such as water) 19 for propagating ultrasonic waves 20 only to the measuring part of reagent 16, a pressure sensor 21 is provided for detecting the pressure of water, and based on a detecting signal outputted by this pressure sensor 21, the fluctuation of interval between the reagent 16 and the probe holder 13 is detected. Besides, the ultrasonic examination device is constituted by utilizing such an ultrasonic probe.
