SAFETY DEVICE FOR A PRE-FILLED SYRINGE AND INJECTION DEVICE
摘要
According to the invention a safety device (1) for a pre-filled syringe (2) comprises a substantially cylindrical and hollow support body (1.2) and a hollow needle shield (1.1) slideably arranged relative to the support body (1.2). The support body (1.2) comprises at least one resilient arm (1.2.3) and the hollow needle shield (1.1) or a needle shield assembly comprises at least one curved actuation ramp (1.1.2). The curved actuation ramp (1.1.2) protrudes in a lateral direction (L) perpendicular to a central axis (A) of the safety device (1). The curved actuation ramp (1.1.2) comprises a first lateral dimension (L1) at a proximal end of the needle shield (1.1) and a second lateral dimension (L2) exceeding the first lateral dimension (L1) at a distal end of the needle shield (1.1). The resilient arm (1.2.3) engages the curved actuation ramp (1.1.2) when the needle shield (1.1) is slid relative to the support body (1.2).
