| 摘要 |
This invention is a skin piercing device which converts a longitudinal linear motion of a blade (5) within the housing (1) of said device into a vertical linear motion, which in consequence of the placement of biasing means (6), restraints and stops (10) in the device, results in the ejection of the blade (5) out of the housing (1) and into the patient's skin and back again into the housing (1) 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. |
