18 Claims

1. Medical transfer device for transferring fluid from a container into a bottle, the neck of which bottle includes a pierceable closing element, and the removal of the transferred fluid moved into the bottle, the medical transfer device comprising:

a) a first tubular-shaped part which is telescopically movable in a second tubular-shaped part between an inserted and an extracted position;

b) a holding part connected with the first tubular-shaped part, the holding part including a conical receiving element to attach an element for releasable and sealable connection of the conical receiving element with the container containing the fluid;

c) a cannula connected with the interior of the conical receiving element and extending from the holding part into the interior of the second tubular-shaped part without extending axially past the second tubular-shaped part in the inserted position for withdrawing fluid transferred into the bottle;

d) a locking mechanism provided for tight locking of the two tubular-shaped parts in the inserted position;

e) the cannula including a lateral opening at its distal end, from which opening the fluid discharges laterally towards a lateral internal wall of the bottle, in use, when the cannula protrudes into the bottle after piercing the closing element; and

f) the two tubular-shaped parts being rotatable against each other through a sufficiently limited angle, so that the first tubular-shaped part is movable into the extracted position after opening the locking mechanism in one rotated position, in which the cannula extends out of the second tubular-shaped part and protrudes through the closing element so far into the interior of the bottle attached to the second tubular-shaped part that the lateral opening in the cannula is facing away from the closing element in the injection direction, while the first tubular-shaped part is sufficiently retractable in another rotated position so that the lateral opening of the cannula is directly in front of the closing element in the injection direction.
