| 摘要 |
The present invention provides a pricking device for taking blood comprising a contact element for being placed into contact with an extraction surface, an actuating element for manual actuation of the pricking device, a pricking element which is used to perforate the extraction surface, the pricking element being arranged in the contact element in such a way that it does not protrude from the contact element before the pricking procedure is initiated, and in such a way that a defined pricking depth is obtained during the pricking procedure. The pricking device further includes a return spring for automatically retracting the pricking element into the contact element after a pricking procedure has been completed and a locking mechanism for locking the pricking device after completion of a single pricking procedure and thereby preventing additional use of the pricking device. |
