Ultrasonic probe lid includes that sheath material is configured to substantially surrounded by ultrasonic probe and transmitting ultrasonic wave transmitting by the action face ultrasonic probe by hyperfrequency for ultrasonic detector. A kind of region contact that the action face by hyperfrequency contacts, which includes the inner surface and the outer surface of region contact area. Airtight petite persons barrier is detachably attached to inner surface contact zone, the outer surface of contact zone, or both. In addition, at least one described barrier include label proving program before removal at least one barrier for executing. Conducting medium can be set in contact zone, the contact zone inner surface and/or outer surface and by being also arranged on inner surface and/or outer surface on respective internally and/or externally barrier layer.
