摘要:
The present disclosure relates to a safety mechanism (27) for a medicament delivery device for preventing activation thereof in the event of mechanical shock. The safety mechanism (27) comprises a medicament delivery member sleeve (7), a proximal flange (9) provided at the proximal end of the medicament delivery member sleeve (7), which proximal flange (9) has a first radially flexible arm (9a) extending longitudinally in the distal direction, a housing (3) having a central proximal opening (3a) arranged to receive a distal portion of the medicament delivery member sleeve (7), wherein the medicament delivery member sleeve (7) is axially displaceable inside the housing (3) from an extended position to a retracted position relative to the housing (3), and a cover (5) having a distal opening (5a) forming a channel arranged to receive the medicament delivery member sleeve (7) and the housing (3). The housing (3) has a proximal portion (3b) arranged between the first radially flexible arm (9a) and the outer surface of the medicament delivery member sleeve (7) when the medicament delivery member sleeve (7) is displaced from the extended position towards the retracted position. The channel is dimensioned such that, when the housing (3) is received by the cover (5), there is a radial distance between the inner surface of the cover (5) and the outer surface of the proximal portion (3b) which is less than a radial dimension of the first radially flexible arm (9a), preventing the medicament delivery member sleeve (7) from obtaining its retracted position.
摘要:
The present invention relates to a needle cover assembly to be used with a medicament delivery device, wherein said needle cover assembly (10) is disposable and comprises a retainer element (50) connectable to the medicament container holder; a hub (16) having a longitudinal axis and comprising a double pointed injection needle (22) with a proximal needle end (24) and a distal needle end (48), wherein the proximal needle end projects a distance from the hub (16) along the longitudinal axis, and a shield (18) covering at least the proximal needle end and a portion of the hub (16). The invention is characterised in that said shield (18) comprises a detachable element (26), that the shield (18) is attached to the hub (16) when said detachable element (26) is attached to the shield (18), corresponding to an untampered state, and that the shield is released and is telescopically movable in relation to the hub (16) along the longitudinal axis when said detachable element (26) is detached from the shield (18) corresponding to an activated state.
摘要:
For use in an injection device, e.g. , an auto-injector of any type, a sleeve which holds the medicament chamber is sufficiently deformable that it functions as a shock absorbing member to distribute the force exerted on the medicament chamber during use of the injection device.
摘要:
An insertion device (110) for inserting an analyte sensor (114) into a body tissue is proposed. The insertion device (110) comprises an insertion needle holder (120) and a drive mechanism (124) for linearly driving the insertion needle holder (120) in a longitudinal direction (126). The drive mechanism (124) comprises at least one actuator (132) for actuating the drive mechanism (124). The actuator (132) comprises at least one actuator arm (136, 138) which is pivotable about at least one axle (140) in order to actuate the drive mechanism (124). The insertion device (110) further comprises at least one protection against reuse including at least one locking mechanism (178). The locking mechanism (178) is adapted to at least partially prevent a back-pivoting of the actuator arm (136, 138) in a direction reversing the actuation direction once the actuator arm (136, 138) has been pivoted by at least one threshold angle.
摘要:
A pen needle outer cover (10) has a molded plastic distal cover (20), and a molded plastic proximal cover (22) in place of the conventional paper-foil label. The proximal cover (22) may be snap-fit over the opening of the distal cover (20). A user-separable section (26) with a finger pull tab (32) is defined by a reduced-thickness membrane (24), which functions as a tear line to allow that section (26) to at least partially separate from the proximal cover (22). A living hinge (27) may be provided to keep the user-separable section (26) from completely separating from the proximal cover (22). The finger pull tab (32) may be configured to enable re-covering of a pen needle (30) that is still within the outer cover (10).
