Piercing system

摘要

System for producing a puncture wound for collecting a sample of body fluid comprises a pressure head (4) for pressing on a body part where the wound is to be produced, a trigger (8) for actuating a puncture needle (3), a test device (5) for determining a parameter on which the probability of sample collection depends, a trigger safety catch (9) that is released when the measured test parameter meets minimum requirements, and a lamp (12) for signaling that the safety catch has been released. Independent claims are also included for: (1) puncture device comprising a pressure head, trigger, needle and test device as above, where the test device is a pressure sensor with a spring against which the pressure head can move relative to a housing (7) into an end position when a minimum pressure is applied; (2) preparing a system as above for producing a puncture wound for collecting a sample of body fluid by determining a parameter on which the probability of sample collection depends and determining if the measured test parameter meets minimum requirements and, if this is the case, releasing the safety catch and signaling that the safety catch has been released.
