Abstract
A removal device for removing at least one low-germ liquid from a conduit system is disclosed. The removal device comprises at least one removal connection piece. The removal device further comprises at least one coupling bend, which is detachably connected to the removal connection piece. At least one tube end of the removal connection piece protrudes into an interior of the coupling bend and is sterilizable with pure steam on its inner face, its outer face and its end face within the coupling bend.
Claims11
A method for removing a low-germ liquid from a conduit system having a removal connection piece, a coupling bend detachably connected to the removal connection piece, and a tube end of the removal connection piece protruding into the coupling bend, the method comprising:
- a) introducing pure steam into the coupling bend;
- and
- b) contacting an inner face, outer face and end face of the tube end with the pure steam for a sufficient time to thereby sterilize the tube end,
- the method further comprising, before step a:
- connecting an electrical contact to the coupling bend;
- connecting the electrical contact to a controller;
- and
- using the electrical contact and the controller to detect whether the coupling bend is connected to the removal connection piece.
A method for removing a low-germ liquid from a conduit system having a removal connection piece, a coupling bend detachably connected to the removal connection piece, and a tube end of the removal connection piece protruding into the coupling bend, the method comprising:
- a) introducing pure steam into the coupling bend;
- and
- b) contacting an inner face, outer face and end face of the tube end with the pure steam for a sufficient time to thereby sterilize the tube end, wherein the steam is introduced through the coupling bend and travels from the coupling bend to the tube end and the removal connection piece.
