Patent Images
1. An apparatus for subcutaneous injection of an injectable product comprising:
- an injection device comprising a container holder, a container and a needle, the container and the needle being connected to the container holder;
an inner sleeve and an outer sleeve connected to a proximal portion of the container, the inner sleeve and the outer sleeve being generally concentric;
a needle protection sleeve shiftable in a shifting direction along a length of travel from a proximal position extending beyond the needle to a distal position where it is positioned generally between the inner sleeve and the outer sleeve; and
an indicator which indicates to the user of the apparatus, during insertion of the needle, that the needle protection sleeve is in the distal position, the indicator comprising a circuit, the circuit being positionable between an open position and a closed position, one of the closed position or the open position indicating that the needle protection sleeve is in the distal position.
