Abstract:
PCT No. PCT/SE92/00249 Sec. 371 Date Oct. 8, 1993 Sec. 102(e) Date Oct. 8, 1993 PCT Filed Apr. 13, 1992 PCT Pub. No. WO92/18182 PCT Pub. Date Oct. 29, 1992.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.
