Abstract: A disposable single-swing-arm incision safety lancet is provided, which includes a casing (2) and a trigger. It is characterized in that the casing (2) is provided inside with an incision blood-taking mechanism composed of a cam (3), a swing arm (4), a blade (1) and a spring (8). In the incision blood-taking mechanism of the present invention, the cam, being driven to rotate under elastic force of the spring, pushes via the curved surface against the swing arm, which thus swings with the third radius R3 as the radius. The point of the blade 1 is swingingly stretched out of the casing 2 from the blood-taking opening 5 along the arc-shaped path A, thus producing the incising action. The present invention is novel in structure, clever in concept, and reliable in working. Since the movement of the incision blood-taking mechanism is controlled by the spring, the action strength can be controlled through the design of elastic force of the spring.

Abstract: The disposable lancet mainly contains a resilient needle body with two arms extended forward into a Y shape with a needle between the two arms. The two arms and the needle of the needle body are housed inside a sleeve member and the combination is slidably installed inside an enclosure.
