Abstract

Dans la présente invention, des trous d'injection et des trous d'évacuation sont formés sur des surfaces horizontales possédant différentes positions verticales de façon à permettre une communication sélective avec des filtres montés dans une partie de filtre, ce qui permet d'empêcher qu'un matériau étranger, ayant été éliminé par filtration d'un médicament liquide précédemment sélectionné, s'écoule conformément au changement de direction du filtre correspondant dans le corps lorsqu'une poignée de robinet d'un robinet multiple est actionnée de telle sorte que le type de médicament liquide à injecter dans le corps est changé. De plus, la présente invention permet l'actionnement de la poignée de robinet du robinet multiple et modifie le trajet d'un médicament liquide à travers les trous d'injection, les filtres et les trous d'évacuation de façon à permettre l'injection plus pratique du médicament liquide.
