Abstract: A skin-puncturing device may include: a main body; a cup configured to close the main body; a puncturing mechanism with a lancet guiding unit; a drive spring of the lancet guiding unit; a driving sleeve; a return spring of the lancet guiding unit; a button configured to tension the drive spring; a member configured to release the tension of the drive spring; a puncture depth regulation mechanism; and a used lancet removal mechanism. The driving sleeve may be configured to rotate within the casing, to slide toward a front part of the device, and to slide toward a back part of the device. The puncture depth regulation mechanism may include: the button, rotary-coupled with the driving sleeve; limiting steps that define relative puncture depths for selection by the driving sleeve; and a bumper of the driving sleeve configured to engage a selected one of the limiting steps.

Abstract: Safety needle device (1) comprising: a hub (10) configured to be connected to a pen-injector, the hub (10) comprising a lateral wall (11) and an upper wall (12) which define therebetween a cavity (13) extending between the upper wall (12) and an lower aperture (14) able to receive the pen injector; a needle (20) attached to the hub (10), the needle (20) extending along a longitudinal direction (X-X) between a distal end (21), configured for insertion into a patient, and an opposed proximal end (22) configured to be connected to the pen injector, a back-end shield (30) slidable along the longitudinal direction (X-X) within the cavity (13) of the hub (10) and rotatable about the longitudinal direction (X-X), the back-end shield (30) being movable irreversibly from an initial position, before connection of the pen injector to the hub (10), to a locking position, after removal of the pen injector to the hub (10) passing through an intermediate position, an elastic member (40) arranged within the cavity (13) and a

Abstract: A safety needle device may include: a hub configured to be connected to a vessel; a needle attached to the hub, the needle extending between a distal end, configured for insertion into a patient, and an opposed proximal end, configured for connection to the vessel; a shield slidable relative to the hub and rotationally constrained, wherein the shield is irreversibly slidable from an initial position, before injection, to a locking position, after injection, passing through an intermediate position; a housing attached to the hub and surrounding: a portion of the hub, a portion of the shield when the shield is in the initial position and in the locking position, and almost totally the shield when the shield is in the intermediate position; and an elastic member biased to push the shield toward the distal end and to resist a longitudinal sliding of the shield toward the proximal end.
