of leaf springs that are compressed when ring 94 is pressed into position and then spring out so that their ends abut annular ring 112 and thereby capture ring 94 and retain it on the body 26 rotating force adjuster ring 94 causes ridges 106 to force flange 96 distally or proximally to adjust the force of main spring 62 when the lancet device 20 is triggered thus the force is adjusted by turning the ring 94 which moves the force adjuster 70 axially to adjust the compression of the main spring 62 force adjustment indicator 114 on body 26 may be aligned with one of the notches 116 on ring 94 allowing the user may set the amount of force with which to deliver the lancet body sleeve 118 includes two semi cylindrical halves which fit around proximal end of body 26 over body spring 120 which extends between cap 122 of body 26 and internal lip 124 of sleeve 118 keys 126 of body sleeve 118 are received in and move axially along keyways 128 of body 26 body spring 120 urges sleeve 118 distally in a resting or loading state sleeve 118 includes shelf 130 having an aperture 132 adapted to receive the cap 134 of the loading rod 136 and the cap 138 of the support rod 140 loading rod 136 and support rod 140 each include a flat edge that abut each other so that the two rods extend through the force adjuster 70 and the ends of the rods are received in the.
