An ultrasonic probe for diagnostic examination of the interior of body cavities.

摘要

An ultrasonic probe for diagnostic examination of body cavity interiors has a chamber (41) containing transmitting medium (46) put in to fill the space of an ultrasonic wave oscillator transducer or the like, coated with and having a jacket cover (32) on its tip, has the chamber filled to be with an ultrasonic wave transmitting medium (46) to improve the introduction of ultrasonic waves into a body cavity, and a sealable pathway to the exterior is provided so that bubbles in said transmitting medium (46) can be easily removed, and medium replenished or replaced. …If bubbles are contained in the transmitting medium (46), or if the characteristics of the medium deteriorate, the quality of the ultrasonic diagnosis image will be reduced. By providing a communicating path (65) between the housing chamber (41) and the exterior, sealed with a closure member (66) which can be opened and closed as necessary, bubble removal and or replenishment or replacement of the medium is facilitated.
