Abstract
Device for injection syringes for intramuscular and subcutaneous injections in human or veterinary medicine, characterized by an essentially tubular sleeve, whose inner diameter is slightly larger than the outer diameter of an associated injection syringe, and which is provided in the interior with at least one clamping-or holding element which releases, when a certain pressure is reached, the forward motion of the syringe body with the needle which is disposed in the sleeve. The length of the sleeve and the position of the clamping element in it are so dimensioned that the needle remains completely in the sleeve before the pressure is applied. After the application of the pressure, the desired depth of injection can be reached outside of the sleeve.
