Abstract

An arrangement for regulating the depth of a puncture including a sleeve, a button placed at one end of the sleeve, a piston with a puncturing tip that is slidably mounted within the sleeve, and a power spring placed between the front of the button and the piston. The other end of the sleeve (1) includes an adjusting ring (3), which has two inwardly directed half-ringed, oblique limiting members (14, 15), which are hit by fin (7) of the piston during puncturing of skin.

Claims

1. Arrangement regulating depth of puncture, used in the device for puncturing comprising sleeve, button placed at one end of the sleeve, piston with the puncturing tip that is slidably mounted within the sleeve, and the power spring placed between the front of the button and the piston, wherein at the other end of the sleeve (1) adjusting ring (3) is mounted, with the opening (4) receiving the puncturing tip (8), which has two inwardly directed half-ringed, oblique limiting members (14, 15), in which during puncturing piston'"'"'s skin, fin (7) of the piston (5) hits.

3. Arrangement according to

claim 1

or

2

wherein the side surface of the adjusting ring (3) is provided with marker (16) and the outer surface of the sleeve (1) is provided with the scale (17) indicating depth of the puncture.

2. Arrangement regulating depth of puncture, used in the device for puncturing comprising sleeve, button placed at first end of the sleeve, piston with the puncturing tip that is slidably mounted within the sleeve, and the power spring placed between the front of the button and the piston, wherein at the other end of the sleeve (1) adjusting ring (3) is mounted, with the opening (4) receiving the puncturing tip (8), which has two inwardly directed half-ringed, arranged in steps limiting members (14, 15), in which during puncturing piston'"'"'s skin, fin (7) of the piston (5) hits.
