Claim 5
Dependent Claim
34 words
The device according to claim 1 , wherein the cap ( 5 ) has a second portion (A 2 ) that is cylindrically-shaped and dimensioned to guide the lancet carrier ( 2 ) therein.
Claim 6
Dependent Claim
29 words
The device according to claim 1 , wherein at least one of the cap ( 5 ) and the lancet carrier ( 2 ) is made from injection-molded plastic.
Claim 7
Dependent Claim
