There is described a skin piercing device which converts a longitudinal linear motion of a blade within the housing of the device into a vertical linear motion which, in consequence of the placement of a spring, restraints and stops in the device, results in the ejection of the blade out of the housing and into the patient's skin and back again into the housing in a rapid "in-out" fashion. The dimensions of the restraints and stops are individually controllable and, as a result, it is possible to achieve a length of cut which is independent of the depth of cut. |
