PROBLEM TO BE SOLVED: To provide a safety needle assembly which is less obtrusive to a user during injection, particularly in observing the point of injection.SOLUTION: A safety needle assembly for an injector is provided, comprising: a needle having a distal end formed for injection; a carrier configured to support and fit the needle to the injector; and a shield for selectively covering the distal end of the needle. The shield includes a proximal end, a distal end, and a sidewall extending therebetween. The sidewall defines a first outer diameter at or adjacent to the distal end, and the sidewall defines at least one outer diameter greater than the first outer diameter at or adjacent to one or more locations located proximally of the first outer diameter. An aperture is provided in the sidewall, adjacent to the distal end of the shield, between the location where the first outer diameter is defined and the location where the at least one outer diameter which is greater than the first outer diameter is defined.SELECTED DRAWING: Figure 9 |
