Abstract

Capteur de pression particulièrement conçu pour être utilisé dans les laboratoires de recherche médicale ou pharmaceutique, pour la mesure de la pression artérielle ou de la pression veineuse par exemple. L'utilisation de chambres interchangeables, pouvant être livrées stériles, sous emballage individuel, apporte à l'utilisateur un grand confort de manipulation. Le dispositif, objet de l'invention, comporte l'emploi de jauges de contrainte qui transforment les mouvements mécaniques en signaux électriques. Il comprend 5 parties : - la chambre 1 interchangeable. - la pièce 5 qui porte la membrane sensible 9 et permet, grâce à une tige 7, l'application des forces au niveau des jauges de contrainte fixées sur un support unique 8. - le corps intérieur du capteur 10, sur lequel sont fixées les pièces en métal ondulé 16 qui servent de support à la pièce 8. Le corps intérieur porte la prise de connexion multi-contacts 17. - le capot de protection 11 qui se visse sur le corps 10. - le câble de connexion interchangeable. La construction robuste et compacte de ce capteur dont toutes les surfaces extérieures sont lisses, sans vis ni trou, en rend le nettoyage très facile.
