Abstract

La présente invention concerne une unité de prévention de contamination d'instrument dentaire, un instrument de traitement dentaire la comprenant, et un appareil d'alimentation en liquide de nettoyage. L'unité de prévention de contamination d'instrument dentaire comprend : un cadre fixe installé sur un trajet d'écoulement à travers lequel un liquide de nettoyage est fourni depuis un appareil d'alimentation en liquide de nettoyage vers un trou d'injection formé dans un instrument de traitement dentaire tiré dans la bouche d'un patient de telle sorte que le liquide de nettoyage peut être injecté dans la cavité buccale du patient à travers le trou d'injection; et une partie d'ouverture/fermeture, installée dans le cadre fixe, pour fermer le trajet d'écoulement lorsque l'alimentation du liquide de nettoyage provenant de l'appareil d'alimentation en liquide de nettoyage est interrompue, afin d'empêcher la matière étrangère dans la cavité buccale du patient d'être aspirée à travers le trou d'injection par la pression négative générée lorsque l'alimentation du liquide de nettoyage est interrompue à partir de l'appareil d'alimentation en liquide de nettoyage, et de contaminer ainsi l'appareil d'alimentation en liquide de nettoyage. L'unité de prévention de contamination d'instrument dentaire, l'instrument de traitement dentaire la comprenant, et l'appareil d'alimentation en liquide de nettoyage, selon la présente invention, ont l'avantage que lorsque l'alimentation du liquide de nettoyage est interrompue à partir de l'appareil d'alimentation en liquide de nettoyage, le trajet d'écoulement à travers lequel le liquide de nettoyage est fourni au trou d'injection de l'instrument de traitement dentaire est bloqué et une matière étrangère dans la cavité buccale est empêchée de s'écouler dans une pièce à main, empêchant ainsi la pièce à main d'être contaminée.
