ABSTRACT:
Disclosed are methods and means for facilitating injection which enable a correct penetration depth of the needle. These improvements are obtainable by using a needle covering device comprising an axially displaceable first tubular sleeve (30) arranged around the front part of said injection apparatus which at its foremost part surrounds the needle (11) over its entire length, and while overcoming a spring force, is axially displaceable rearwards to expose a predetermined length of the needle, said device further comprises a stationary outer tubular sleeve (40) releasably attached to the injection apparatus and fitted around the front part of said injection apparatus and an inner adjustable tubular stopping sleeve (20) which is axially displaceable between at least two predetermined positions while performing a sliding, helical motion around said front part of said injection apparatus when setting the distance between the foremost part of said stopping sleeve and a stopping flange (31) arranged on the inside of the axially displaceable first sleeve.
