Device for adjusting needle insertion depth
First Claim
1. A penetration depth adjusting mechanism for a medicament delivery device, which extends a longitudinal axis comprising:
- a medicament delivery device housing having a proximal end and a distal end;
a medicament container arranged entirely inside of the medicament delivery device housing, wherein the medicament container is provided with a medicament delivery member;
a medicament delivery member cover coaxially arranged and movable in relation to the medicament delivery device housing;
the penetration depth adjusting mechanism comprising;
a delivery member protruding adjuster operably connected to the medicament delivery member cover of the medicament delivery device and further comprises a signal generating mechanism arranged between the delivery member protruding adjuster and the medicament delivery member cover such that when the delivery member protruding adjuster is moved in relation to the medicament delivery member cover an audible and/or tactile and/or visual signal is generated,wherein the medicament delivery member cover together with the delivery member protruding adjuster are movable in relation to the medicament delivery device housing from a first position in which the medicament delivery member is surrounded by the medicament delivery member cover or by both the medicament delivery member cover and the delivery member protruding adjuster, to a second position in which the medicament delivery member is enabled to protrude a depth measured from a proximal end of the delivery member protruding adjuster,wherein the signal generating mechanism further comprises first signal elements arranged on the medicament delivery member cover of the medicament delivery device and second signal elements arranged on the delivery member protruding adjuster such that the first and second signal elements are able to interact with each other when displacement of the delivery member protruding adjuster occurs in relation to the medicament delivery member cover to thereby providing the audible and/or the tactile and/or the visual signal, and the first signal elements comprise at least one flexing element flexible in a direction generally perpendicular to a longitudinal axis of the penetration depth adjusting mechanism, andwherein the first signal elements further comprise at least one protrusion and the second signal elements comprise a plurality of recesses, wherein the plurality of recesses correspond to a plurality of medicament delivery member protruding depth setups, wherein, when the at least one protrusion is moved in position with one of the plurality of recesses, the at least one flexing element will cause a sudden movement of the at least one protrusion into the one of the plurality of recesses, causing an impact, thereby providing the audible and/or the tactile and/or the visual signal indicating that one of the medicament protruding depth setup of the plurality of medicament delivery member protruding depth setups has been set.
