Device for Controlling a Penetration Depth of Injection Needle
First Claim
1. A device for controlling a penetration depth to which an injection needle penetrates a body of a human or an animal, wherein the device comprisesa first sleeve,an injection needle that protrudes a distal end of the first sleeve (3) in a distal direction anda second sleeve that receives the first sleeve,wherein penetration depth of the injection needle corresponds to an axial translation of the first sleeve with respect to the second sleeve, whereby the axial translation is adjustable by a screw coupling characterized in that a radial protruding indicator disc is formed to the injection needle and a transparent indicator means with at least one calibration mark indicates the penetration depth of the injection needle.

Abstract
According to the invention, a device for controlling a penetration depth to which an injection needle penetrates a body of a human or an animal comprises
- a cylindrical first sleeve,
- an injection needle that protrudes a distal end of the first sleeve in a distal direction and
- a cylindrical second sleeve that receives the first sleeve.
The penetration depth of the injection needle corresponds to an axial translation of the first sleeve with respect to the second sleeve. The axial translation is adjustable by a screw coupling.
