Abstract

L'invention concerne un capteur de pression pour indiquer la pression régnant dans le corps humain ou un animal, qui comprend un boîtier, un souf et contenu dans ce boîtier, des moyens pour placer ledit soufflet en communication avec la pression du corps, de sorte que cette pression déplace ledit soufflet en fonction de son intensité, des moyens contenus dans ledit boîtier associés audit soufflet pour produire un signal de sortie qui est fonction du mouvement dudit soufflet et qui est appliqué à un récepteur situé à l'extérieur dudit corps afin de produire des informations indiquant ladite pression, et des moyens pour étalonner ledit appareil in vivo en reproduisant pendant cet étalonnage in vivo un signal qui a été établi pendant un étalonnage in vitro.
