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); a needle (20) attached to the hub (10), 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 acting between the upper wall (12) and the back-end shield (30) to urge the back-end shield (30) towards the proximal end (21) of the needle (10) along the longitudinal direction (X-X), a locking arrangement (50) comprising at least a first locking member (60) formed on the back-end shield (30) and at least a second locking member (70), the second l

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.

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: Safety needle device (1) comprising: a hub (10) configured to be connected to a vessel, a needle (20) attached to the hub (10), the needle (20) extending along a longitudinal axis (X-X) between a distal end (21), formed for insertion into a patient, and an opposed proximal end (22) formed to be connected to the vessel, a shield (30) slidable relative to the hub (10) along the longitudinal axis (X-X) and rotationally constrained around the longitudinal axis (X-X), the shield (30) being slidable irreversibly from an initial position, before injection, to a locking position, after injection passing through an intermediate position, a housing (40) attached to the hub (10) and surrounding a portion of a portion of the hub (10) and a portion of the shield (30), an elastic member (50) arranged within the housing (40) and acting the shield (30), the elastic member (50) being biased to push the shield (30) towards the distal end (21) of the needle (10) and contrast a longitudinal sliding of the shield (30) towards the

Abstract: The device is comprised of oblong main body and the cup, which locks the front end of the main body. A casing of the main body is shaped as a tube. A puncture mechanism with a lancet leading unit, a puncture depth regulation mechanism and used lancet removal mechanism are installed in the casing. They compose a mechanism unit, which components are installed in a mechanism body, fastened inside the casing. The lancet leading mechanism is comprised of a lancet socket with guide, that goes through the opening in the transversal partition of the mechanism body, and lancet chamber. The guide is linked with the front end of a driving sleeve, sliding and rotary fitted in the mechanism body. Between the transversal partition and the driving sleeve there is the return spring. Between the driving sleeve and a button there is the drive spring. At the end of the casing there is the button, sliding and rotary fitted.

Abstract: The device comprises an elongated needle embedded in a hub equipped with means for connecting the needle with a vessel containing an injectable substance or a vessel for receiving tissue, a housing mounted on the hub, a hollow slider with its first end directed towards the outside of the housing and the second end moving inside the housing and means preventing slider rotation in relation to the housing. The device also includes a longitudinal resilient means supported with its first end against the slider and with its second end against the hub, blocking means stopping the slider's movement in a position most extended from the housing after removal of the needle from the patient's body. The housing features a cylindrical channel in which there is a rotating sleeve and the longitudinal resilient means. The side wall of the sleeve features a linear notch with a start bay and a blocking bay.
