Needle protection device
First Claim
1. A needle-protecting device, comprising:
- a needle (6) extending from the device in a forward direction when un-protected, said needle having a tip (8) at a forward end thereof;
a rigid front part (10) including a chamber (16) therein and a hole (14) in said front part (10);
a flexible and extensible rear part (12) connected to said front part, said rear part extensibly movable relative to said front part between a position of preparedness and an activated position, said front part and said rear part when in the position of preparedness surrounding the needle circumferentially and being spaced from a tip (8) of the needle (6);
means for locking disposed within the chamber (16) and coupled to said front part, said means for locking in said position of preparedness allowing the needle (6) to pass through the hole (14) and in the activated position of said front part and said rear part preventing the needle (6) from passing through the hole (14), said means for locking including a resilient member (26;
36;
46) which in said position of preparedness is under tension, exerting a force substantially at right angles to a longitudinal direction of the needle (6);
a portion of the needle being supported by said hole (14) in the front part (10) such that the resilient member (26;
36;
46) is maintained under tension in said position of preparedness, and after the front part and the rear part pass from the position of preparedness to the activated position and the needle (6) is moved rearwards relative to the front part (10) the resilient member (26;
36;
46) prevents the needle (6) from passing through said hole (14).

Abstract
A device for protecting a needle in medical equipment includes a rigid front part connected to a flexible rear part. The front and rear parts surround the needle circumferentially. A locking mechanism is accommodated in a chamber provided in the front part. In a position of preparedness, the locking mechanism allows the needle to pass through a hole or in the front part. In an activated position, it presents the needle from passing through. In the position of preparedness, the parts are spaced from the tip of the needle. The locking mechanism is a resilient member which in the position of preparedness is maintained under tension, exerting a force substantially at right angles to the longitudinal direction of the needle, so that the tip of the needle, in the position of preparedness, is supported by the hole or the channel. The resilient member is thus maintained under tension and prevents the needle from passing through the hole after it passes from the position of preparedness to the activated position when the needle is moved rearwards relative to the front part.
