Patent ID: 6852119

Claim:
An adjustable disposable lancet device, comprising: a) an elongated body having a closed proximal end and an open distal end, said body having an internal chamber; b) a barrel slidably mounted in said chamber and protruding distally from said open distal end of said chamber, said barrel having an internal sub-chamber open proximally and distally; c) a lancet received within said chamber and sub-chamber and having a distally facing needle; d) said barrel having a distal opening to which a selector tip is attached; and e) means interconnecting between said barrel and selector tip for adjusting a total length of said barrel and selector tip to adjust depth of penetration of said needle past said selector tip, said interconnecting means comprising: i) a radially open part-circumferential ramp; and ii) a follower pin riding in said ramp; iii) whereby relative rotation of said selector tip with respect to said barrel in a first direction increases said total length, and relative rotation of said selector tip with respect to said barrel in a second direction reduces said total length.
