| 摘要 |
The present invention comprises a sampling device having a sleeve (1), a push element (2) mounted at a first end of the sleeve (1), a piston (5) having a fin (7) and a puncturing tip (8) extending from the fin (7), the piston (5) being slidably mounted in the sleeve (1), a drive spring (10) positioned between the end face (9) of the push element (2) and the piston (5), wherein at the other end of the sleeve (1) an adjusting ring (3) is mounted having an opening (4) for receiving the puncturing tip (8), the adjusting ring having two inner semi-annular limiting members (14, 15) each having a substantially oblique abutment surface, against which, the fin (7) of the piston (5) abuts during use. The device allows the depth to which the puncturing tip pierces the skin of a patient to be adjusted when taking blood samples, for example. <IMAGE> |
