Definitions
- Figure 3 Show an exploded view of an example of a hidden needle assembly.
- Figure 8 A-C Show a cross section of the hidden needle assembly of figure 6.
- Figure 9 Show an exploded view of an example of a hidden needle assembly.
- the locking element 260 is on its outside surface equipped with a number of axially extend- ing ribs 262 and the shield 240 is on its inside surface provided with similar inwardly pointing ribs 242. In the initial position the axially extending ribs 262 of the locking element 260 abuts the inwardly pointing rib 242 of the shield 240 thereby preventing the rib from telescoping relatively to the hub 201.
- the safety shield 440 is further provided with a number of inwardly pointing ribs 442 on its inside surface.
- the outer shield 530 is rotational mounted on the hub 501 carrying the needle cannula 510 by a groove 535 in the outer shielded 530 engaging a similar raised ring 513 on the hub 501 , and the rotational movement is controlled by the click arms 512 and the track 534 inside the outer shield 530.
- the hub 501 is further provided with suitable connecting means 502 for connecting the needle assembly to an injection device 520.
- This embodiment discloses a similar needle assembly however, the locking element 960 is only provided with one arm 963. Further, the spring element 950 can be replaced by an elastic sponge 950A as disclosed in figure 2OA. In fact in any of the embodiments disclosed any element providing a biasing force can be used instead of a spring.
