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. A puncturing device for regulating depth of puncture comprising:

a sleeve having a first end and a second end;

a button disposed at the first end of the sleeve;

a piston slidably mounted within the sleeve, wherein the piston has a puncturing tip and a fin;

a spring between the button and the piston; and

an adjusting ring mounted at the second end of the sleeve, wherein the adjusting ring has an opening for receiving the puncturing tip, wherein the adjusting ring has two inwardly directed half-ringed, oblique limiting members, and wherein the fin of the piston hits the limiting members during puncturing of a paient'"'"'s skin.

2. The puncturing device of claim 1, wherein the adjusting ring has a side surface that is provided with a marker and wherein the sleeve has an outer surface that is provided with a scale indicating depth of puncture.

3. A puncturing device for regulating depth of puncture comprising:

a sleeve having a first end and a second end;

a button disposed at the first end of the sleeve;

a piston slidably mounted within the sleeve, wherein the piston has a puncturing tip and a fin;

a spring between the button and the piston; and

an adjusting ring mounted at the second end of the sleeve, wherein the adjusting ring has an opening for receiving the puncturing tip, wherein the adjusting ring has two inwardly directed half stepped limiting members, and wherein the fin of the piston hits the limiting members during puncturing of a patient'"'"'s skin.

4. The puncturing device of claim 3, wherein the adjusting ring has a side surface that is provided with a marker and wherein the sleeve has an outer surface that is provided with a scale indicating depth of puncture.
