Zusammenfassung:A valve assembly is provided which includes a housing having an inlet end and an outlet end and defining a fluid channel and a central chamber. A dissolvable valve member is positioned to obstruct flow through the channel within the chamber. The dissolvable valve member is formed of a material which is dissolvable at a predetermined rate upon contact with a preselected fluid. The preselected fluid is selected from the group consisting of blood, urine, saline and antimicrobial solutions. The dissolvable valve member can be formed from a fluid soluble glass or a starch based material. Se proporciona un montaje de válvula el cual incluye un alojamiento que tiene un extremo de entrada y un extremo de salida y que define un canal de fluido y una cámara central. El miembro de válvula soluble se coloca para obstruir el flujo a través de un canal dentro de la cámara. El miembro de válvula soluble se conforma de un material el cual es soluble a una velocidad predeterminada al contacto con un fluido preseleccionado. El fluido preseleccionado se selecciona del grupo que consiste de sangre, orina, solución salina y soluciones antimicrobianas. El miembro de válvula soluble se puede conformar de un vidrio soluble en fluido o un material basado en almidón.
