Abstract

The apparatus has a device limiting penetration of the needle (1). One end of the needle has a head (2) with a conical portion (3) for connection to a syringe cone while the other end of the head accommodates the limiting device. The needle end of the head can be conical, and a friction fit inside the conical portion of the device. There can be a chamber in the needle end of the head, connected at one end to the taper bore (4) at the syringe end, and at the other to the drilling inside the needle. A plug can be provided, with a stem shorter than the needle and leaving a space between it and the walls of the drilling in the latter, while the head moves to and fro in the chamber (6) at the needle end of the head.
