JPS645566A - Apparatus for allowing inside and outside of living body to communicate with each other - Google Patents

Abstract

PURPOSE:To easily perform mounting and detachment by a simple structure and to prevent the leakage of a liquid at a connection part, by constituting the title apparatus of a living body embedded plug and an outside cylindrical port and connecting both of said plug and the cylindrical port by magnetic force to allow the inside and outside of a living body to communicate with each other. CONSTITUTION:A living body inside and outside communication apparatus 1 is constituted of the living body embedding plug P embedded in a living body B, the drug solution tank out of the living body and an outside cylindrical port T attached to the pipe N connected to an excretion bag. The outside cylindrical port T is inserted in the opening port K of the living body embedding plug P mounted to the living body B and fixed to the living body embedding plug P by attracting the magnetic force acting body F arranged to the outer periphery of the leading end of the outside cylindrical port T. In this case, the liquid passing through the passing hole U of the outside cylindrical port T and the communication hole R of the living body embedding plug P is not leaked by bringing the leading end surface of the outside cylindrical port T into contact with a seal ring L. The outside cylindrical port T is detached from the living body embedded plug P against the attraction force of a permanent magnet M by pulling the projection part (t) formed to the outside cylindrical port T by a hand.
