A single-use, spring driven lancet is described. The device is precocked during assembly so that the user needs only to remove the safety cap prior to use. A concave trigger button with direct up and down motion releases the spring, causing the tip of the lancet to strike the subject's finger. A thin plastic fiber connection between the pull-tab and the needle safety cap prevents any compressive force from being applied to the drive spring, which effectively prevents recocking of the device.
