Abstract: A resistance control device includes a resistance generating unit and a control unit. The resistance generating unit is adapted to be disposed proximate to an outer periphery of a flywheel, and includes a magnetic member having a pivotal end, and a free end that is adapted to be biased toward the flywheel, and a driven module disposed proximate to the free end of the magnetic member, and connected to the magnetic member. The control unit includes a cam rotatably operable to move the driven module such that, the magnetic member is driven to pivot toward or away from the flywheel. The cam is located between the driven member and a rotating axis of the flywheel so as to block the free end of the magnetic member from contact with the flywheel.

Abstract: A blood sampling device contains: a body, a fitting sleeve, and an adjusting sleeve. The body includes a lancet, a driving edge for driving the lancet, a control switch for controlling the driving edge, and a connecting section. The fitting sleeve includes a first fitting section, a second fitting section, and a connecting groove, wherein the second fitting section has a coupling portion for connecting with the connecting section. The fitting sleeve further includes a trench, an outlet, and a fixing rib. The adjusting sleeve includes a coupling section, a controlling section opposite to the coupling section, a tilted guiding slot for retaining with the fixing rib, and an exit corresponding to the outlet, The second fitting section of the fitting sleeve has a transparent window for viewing the coupling section of the adjusting sleeve, and the coupling section has a length identification portion injection molded thereon.

Abstract: A blood sampling device contains: a body, a fitting sleeve, a triggering block, a trigger spring, and a switch. The body is hollow and fits with the fitting sleeve which includes an exit for extending a lancet out of the exit, and the body includes a first fixing position and a second fixing position. The first fixing position is an untriggering position away from the exit, and the second fixing position is a triggering position close to the exit. A first end of the triggering block abuts against the trigger spring, the triggering block includes a connecting orifice for accommodating the lancet and includes an elastic piece retaining at the first fixing position or the second fixing position. The switch is mounted on the body and includes a releasing segment corresponding to the first fixing position so as to release the elastic piece from the first fixing position.
