Aspects of the invention include drug delivery systems comprising a syringe stopper rod that comprises a sensor component comprising a wireless transmitter module and an activation component configured to activate the sensor component when the syringe stopper rod has completed a delivery stroke, wherein the wireless transmitter module is configured to transmit a report comprising a drug dose completion signal when the sensor component is activated.

A medicament delivery device is presented having a housing, a delivery member cover slidably arranged in the housing, a medicament container housing arranged in the housing, a forward-biased rotator structure configured to move the medicament container housing in a forward direction in the housing, wherein the delivery member cover is configured to be moved axially from an extended position relative to the housing to a retracted position, thereby causing the rotator structure to rotate from a first rotator position to a second rotator position, and a forward-biased plunger rod extending axially inside the rotator structure and having a first axial engagement position with the rotator structure when the rotator structure is in the first rotator position and the second rotator position, the rotator structure having a first rotator guide track structure configured to cooperate with an inner surface structure of the housing.

A drug delivery device is provided, including a housing, a drug storage container, a plunger, a plunger biasing member, a releaser, and a shock absorber. The housing defines a longitudinal axis and has an opening. The drug storage container includes a barrel, a stopper, and a delivery member, where the stopper is movably positioned within the barrel. The delivery member is positioned at a distal end of the barrel and has an insertion end configured to extend at least partially through the opening during a delivery state. The plunger is moveable toward the distal end of the drug storage container to engage the stopper and expel a drug from the drug storage container through the delivery member. The plunger biasing member is coupled with the plunger and configured to urge the plunger toward the distal end of the drug storage container. The releaser member has a first position wherein the releaser member prevents the plunger from moving into the delivery state and a second position wherein the releaser member does not prevent the plunger from moving into the delivery state. The shock absorber is configured to absorb an impact force and prevent unintended movement of the releaser member.

A needle protection assembly, adapted to protect a tip of a hypodermic needle, comprising a shield adapted, in a protected operative orientation of the needle protection assembly, to shield the tip of the hypodermic needle, a locking element including at least one slot, the slot including at least three surfaces corresponding to three operative orientations of the shield, at least one slot engaging element, functionally associated with the shield, the slot engaging element being disposed within the slot of the locking element and movable relative thereto, between the surfaces, so as to transition the shield between the three operative orientations, and at least one biasing element, adapted for axial biasing of the shield, wherein the three operative orientations include a storage operative orientation, an injection operative orientation, and a needle protection operative orientation.

A housing for a medicament delivery device is presented having a shell extending along an axis in an axial direction from a proximal end to a distal end, and a medicament delivery member guard moveably attached to the shell. The medicament delivery member guard extends in the axial direction from a proximal end to a distal end. The shell has a slit extending in the axial direction and the medicament delivery member guard has a protrusion extending in the axial direction, and/or the medicament delivery member guard has a slit extending in the axial direction and the shell has a protrusion extending in the axial direction. The medicament delivery member guard is configured to move in the axial direction from a first axial position relative to the shell (12) to a second axial position relative to the shell.

A drive assembly for a medicament delivery device having a driver rotationally driven, an actuator sleeve, and a resilient blocking member that surrounds the driver and is arranged radially inside of the actuator sleeve, wherein the blocking member engages with the driver to prevent rotation of the driver relative to the blocking member, the actuator sleeve being configured to move from a first position relative to the blocking member, in which the drive assembly is in an initial state and in which the actuator sleeve is configured to prevent the blocking member from moving radially outwards, causing the blocking member to engage with the driver and thereby prevent the driver from rotation, to a second position in which the drive assembly is in an activation state.

An assembly for receiving a medicament container having a container carrier extending along a longitudinal axis, the container carrier having a carrier body, and a flexible carrier arm extending from the carrier body substantially parallel with the longitudinal axis; and a rotator comprising a hollow rotator body and a through hole which extends substantially parallel with the longitudinal axis, wherein the container carrier is arranged to receive the rotator such that the carrier arm extends through the through hole, and wherein the rotator is arranged to rotate about the longitudinal axis and relative to the container carrier. A cassette and a medicament delivery device are also provided.

A medicament delivery device is presented having a housing with an inner surface structure, a delivery member cover slidably arranged in the housing, a medicament container housing arranged in the housing, a rotator configured to cooperate with the inner surface structure, the rotator being in axial engagement with the medicament container housing, wherein the delivery member cover is configured to be moved axially from an extended position relative to the housing to a retracted position, thereby causing the rotator to rotate from a first rotator position to a second rotator position, a forward-biased plunger rod extending through the rotator and having a first axial engagement position with the rotator when the rotator is in the first rotator position and in the second rotator position, wherein the rotator has an engagement structure configured to engage with the inner surface structure when the rotator is in the first rotator position to prevent forward movement of the rotator, and wherein the rotator is configured to disengage from the inner surface structure when the rotator is rotated from the first rotator position towards the second rotator position, causing the rotator, the plunger rod and the medicament container housing to move forward an auto-penetration distance in the housing.

A method for medicine administration and tracking and system for the same that may implement the method via a health management application running on a computing device includes tracking movement of an injection pen from a start location to a dispensing location, detecting a dispensing event of medicine dispensed from the injection pen at the dispensing location, determining a location of the dispensing location relative to a user's body, associating information relating to the detected dispensing event with information relating to the determined location, and providing feedback based upon the detected dispensing event information and the determined location information.

The present disclosure relates to a disposable injection needle including: a needle mount having a tube needle; a first sleeve, one end of which is suitable for connecting to the needle mount to define receiving space, and the other end of which is provided with a first opening; a second sleeve, one end of which is located inside the receiving space, and the other end of which having a second opening; an elastic element adapted to allow the second sleeve moves axially toward outside the receiving space, wherein: the needle mount or the first sleeve is provided with a stop surface and a limit groove; the second sleeve is provided with a limit arm comprising a limit face and a protruding member which is adapted to enter the limit groove with axial relative movement between the first sleeve and the second sleeve.
