Abstract

L'invention concerne une poche réceptrice d'un dispositif à poche d'eau utilisé dans une sonde à ultrasons, constituée d'un caoutchouc mince, de l'eau ou une solution aqueuse étant reçue dans la poche. Lorsque la poche est conservée pendant une longue durée, l'eau ou la solution aqueuse reçue s'évapore (pour être transformée en vapeur), ceci à pour effet de diminuer le volume de la poche ou de dégonfler ladite poche. Un trou de passage est ménagé dans une partie périphérique extérieure d'un corps de cadre (cassette), une partie annulaire d'une poche de réception dilatable est ménagée dans une forme évidée, une partie saillante annulaire est prévue sur la surface périphérique extérieure de la forme évidée et un trou traversant est ménagé dans une partie périphérique extérieure d'une garniture circulaire en forme de plateau. Les centres du trou dans la partie périphérique extérieure du corps de cadre et le trou dans la partie périphérique extérieure de la garniture circulaire en forme de plateau sont alignés coaxialement en une ligne de telle sorte qu'un tube creux peut pénétrer par les trous.
