An autoinjector comprises a housing, a product container, a displaceable needle protection sleeve, a plunger rod displaceable by a preloaded discharge spring, a dose setting element with at least two different rotational positions relative to the housing, and a dosing sleeve. The dosing sleeve or the plunger rod has a dose selection stop, and the other has at least one dosing stop. By rotating the dose setting element, the dosing sleeve or the plunger rod is rotated relative to the other. Upon displacement of the needle protection sleeve, the spring displaces the plunger rod, whereby, if the dose setting element is in the first rotational position, the dose selection stop and the first dosing stop strikes against each other, and, if the dose setting element is in the second rotational position, one of the dose selection stop and the first dosing stop is or can be moved past the other.

The disclosure relates to a sheath removal mechanism (15) for removing a protective needle sheath (5) from a medicament container (3), the medicament container (3) arrangeable in an medicament delivery device (1), wherein the sheath removal mechanism (15) comprises a cap (11) attachable to a distal end of the medicament delivery device (1), wherein the cap (11) comprises at least one ledge (11.6) adapted to engage a protective needle sheath (5).

A device for delivery of a medicament from a container (10) having an outlet (16) at a distal end of the container (10) and a stopper (22) for containing the medicament in the container (10) is disclosed. The device comprises a housing (110, 140), a drive element (300) arranged to move in the distal direction to cooperate with the container (10), a drive mechanism comprising a trigger component (200), the drive mechanism being arranged to hold the drive element (300) in a starting position and to move the drive element (300) in the distal direction from the starting position upon displacement of the trigger component (200) from a working position to a firing position, an interlock component (250) received in the housing (110, 140) and arranged for movement with respect to the housing (110, 140) from a first position to a second position, and at least one flexible locking member (214) arranged to cooperate with a slop face (160) associated with the housing (110, 140) to prevent displacement of the trigger component (200) to the firing position when the interlock component (250) is in the first position. Movement of the interlock component (250) towards the second position causes bending of the flexible locking member (214) away from the stop face (160) to allow displacement of the trigger component (200) to the firing position.

An autoinjector comprises a housing, a product container, a displaceable needle protection sleeve, a plunger rod displaceable by a preloaded discharge spring, a dose setting element with at least two different rotational positions relative to the housing, and a dosing sleeve. The dosing sleeve or the plunger rod has a dose selection stop, and the other has at least one dosing stop. By rotating the dose setting element, the dosing sleeve or the plunger rod is rotated relative to the other. Upon displacement of the needle protection sleeve, the spring displaces the plunger rod, whereby, if the dose setting element is in the first rotational position, the dose selection stop and the first dosing stop strikes against each other, and, if the dose setting element is in the second rotational position, one of the dose selection stop and the first dosing stop is or can be moved past the other.

A safety needle device is disclosed having a housing configured to couple to a syringe, the housing having a proximal end, a distal end, and a housing body. A needle hub is disposed on the proximal end of the housing and a needle cannula is attached to the needle hub. The device having a retractable sheath configured to move between an initial position, a retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula. The safety needle device may include an activation latch, a lockout latch, a tether and a spring element to bias the retractable sheath to an extended state to cover the distal end of the needle cannula upon completion of an injection. The safety needle device may include a slider element disposed above an activation latch. A method of drug delivery is also disclosed.

Provided is a medical needle that reduces a user's discomfort feeling while securely housing a needle tip into a case. Medical needle 1 includes needle portion 10 including needle tip 14 at the head thereof; case 30 configured to be capable of exposing needle portion 10 from the head thereof and housing the needle portion; movement mechanism 50 including spring member 60, which is located in case 30, configured to move needle portion 10 from a first position at which needle tip 14 protrudes from case 30 by a predetermined length to a second position at which needle tip 14 is housed in case 30; and curved portion 90 provided in a portion which is in movement mechanism 50 and faces case 30.

A safety syringe (100; 700; 1200) comprising: a barrel (104; 704; 1204) having an opening at an end thereof; a syringe plunger (108; 708; 1208) configured to move within the barrel such that an inward stroke of the syringe plunger causes a substance within the barrel to be expelled from the opening; and a sheath (112; 712; 1212) configured to cover at least partially the opening in the barrel after use of the syringe, wherein the sheath is coupled to the syringe plunger and is configured to decouple from the syringe plunger at a point on the inward stroke such that the sheath is moveable independently of the syringe plunger and further movement of the sheath after decoupling at least partially covers the opening in the barrel.

Provided is a cap for an injector comprising a syringe with a needle cover. The cap comprises a first cap body part in the form of a sleeve having forward and rear openings; a second cap body part in the form of a plug arranged for receipt by said forward opening of said sleeve form first cap body part, wherein said plug form second body part defines a plug top and an inner plug body, and wherein said inner plug body defines a protruding pocket; and arranged for receipt within said protruding pocket of the inner plug body, a metal connector defining plural needle cover gripping elements arranged around a central hub, wherein each gripping element is provided with one or more barbs for gripping the needle cover. The first cap body part, second cap body part and connector are provided as separate parts. In the assembled cap, the plug top of the plug form second cap body part forms a cover for the forward opening of the sleeve form first cap body part, and the needle cover gripping elements of the connector extend into the sleeve form first cap body part.

A communication device arranged for transmitting information from a medicament delivery device is presented. The communication device includes at least one translation detection arrangement, configured to detect a translation of at least one physical part of the medicament delivery device by utilization of a resilience and an electrical conductivity for at least one spring of the medicament delivery device. The communication device also includes at least one change of state detection unit, configured to detect at least one change of state for the medicament delivery device based on the detected translation. The communication device further includes at least one activation unit, configured to activate the at least one change of state detection unit based on the at least one detected translation. The communication device also includes at least one transmission unit configured to provide a wireless transmission of information related to the at least one change of state to an external receiving device.

A safety syringe (100; 700; 1200) comprising: a barrel (104; 704; 1204) having an opening at an end thereof; a syringe plunger (108; 708; 1208) configured to move within the barrel such that an inward stroke of the syringe plunger causes a substance within the barrel to be expelled from the opening; and a sheath (112; 712; 1212) configured to cover at least partially the opening in the barrel after use of the syringe, wherein the sheath is coupled to the syringe plunger and is configured to decouple from the syringe plunger at a point on the inward stroke such that the sheath is moveable independently of the syringe plunger and further movement of the sheath after decoupling at least partially covers the opening in the barrel.
