摘要：
A needle assembly, comprising: a needle (110) having a sharp end and an opposite end, the needle being insertable through a base (102)； and a needle protection device (188), comprising: a first protection connectable to one of the base (102) and a fluid connector (126) connectable to the base (102), the first protection being connected in a manner fixed to the opposite end of the needle and having at least one cantilever arm with a tapered edge (200)； a second protection having a stop (198), wherein in a first position of the second protection with respect to the first protection, in which the sharp end of the needle is exposed outside the second protection, the stop (198) is coupled with the tapered edge (200) of the first protection to create a pressure connection (jamming) with the one between the base (102) and the fluid connector (126), the first and second protections having a central axis common； and a deflection element that axially deflects the first protection away from the second protection； wherein the proximal displacement of the second protection with respect to the one between the base (102) and the fluid connector (126) proximally displaces the first protection together with the second protection until the first protection is no longer connected to the one of between the base (102) and the fluid connector (126)； and where when the first protection is no longer connected to the one between the base (102) and the fluid connector (126), under the force of the spring (194), the cantilever arm of the first protection deviates from to the stop (198) and the first protection moves axially with respect to the second protection to cover the sharp end of the needle.Un conjunto de aguja, que comprende: una aguja (110) que tiene un extremo afilado y un extremo opuesto, siendo la aguja insertable a través de una base (102)； y un dispositivo (188) de protección de aguja, que comprende: una primera protección conectable a uno de entre la base (102) y un conector (1
