Application No. 09/393,256
The outer surface of cylinder 5 is provided at its free end 9 with a resilient
annular structure 30 that projects above that end. This structure is a shallow and soft
rubber ring that is cemented to cylinder 5 where it comes into contact with it. The
section of resilient annular structure 30 that projects beyond the free end 9 of cylinder 5
is slightly larger than the section cemented to the cylinder. A contacting agent 32, a gel
for example, is introduced into the space between free end 9 and the free end 31 of
resilient annular structure 30 and surrounded by that structure. In addition, ultrasonic
head 1 and handle 2 are provided with a protective rubber coating 33 and that the
coated area is shaped more or less like a tobacco pipe. Protective coating 33 covers
resilient annular structure 30 up to the level of the free end 9 of cylinder 5.
The ultrasonic head 1 with the resilient annular structure 30 surrounding the
contacting agent 32 and with the cylinder 5 secured to the handle 2 and extension 3
can be used to determine whether if a female animal, that might constitute some
danger to an examiner, is gravid. Handle 2 and extension 3 make it possible to extend
ultrasonic head 1 over wide distances, and resilient annular structure 30 prevents
rubbing off the contacting agent when the head is moved over the animal's skin or hair,
leaving a cushion of air between the ultrasonic head and the air to contaminate or
prevent results.
