Abstract: front page image
(EN)An endoscope fluid control input device comprises an operating button (3) for effecting the switching of the kind and flow rate of a fluid supplied to a pipeline in an endoscope by push-in capacity, an urging spring (7) for restoring an operating button (3) to its predetermined position, an optical sensor (2) which causes generation of a signal corresponding to the push-in position of the operating button (3), a rubber cover (25) water-tightly covering all structural members, and a click spring (6) and a projection (3a) which cooperate with each other to produce a temporary and sharp change in capacity simultaneously with, or at a predetermined time before or after the occurrence of, a signal generated according to a change in the position of the operating button (3). And the fact that a signal has been generated from the optical sensor (2) is made known to the operator by the change in capacity brought about by the cooperation between the click spring (6) and projection (3a).
(FR)L'invention concerne un dispositif d'entrée de régulation d'un fluide endoscopique, équipé d'un bouton (3) de commande de commutation du type et du débit d'un fluide injecté dans le tuyau d'un endoscope par compression, d'un ressort (7) permettant de remettre le bouton (3) de commande sur sa position prédéterminée, d'un capteur optique (2) générant un signal correspondant à la position de compression du bouton (3) de commande, d'un couvercle (25) en caoutchouc étanche recouvrant tous les éléments structurels, et d'un ressort (6) d'encliquetage et d'un élément saillant (3a) associés de manière à générer un changement de capacité temporaire et radical de manière simultanée avec, ou à un moment prédéterminé avant ou après l'occurence d'un signal généré en fonction d'un changement de position du bouton (3) de commande. La génération du signal par le capteur optique (2) est indiquée à l'opérateur par le changement de capacité généré par le ressort (6) d'encliquetage associé à l'élément saillant (3a).
