The invention relates to an injection device comprising a housing, a container holder arranged within said housing, the container holder being configured for accommodating a medicament container having a needle attached to one end thereof and a stopper sealingly and slidable arranged inside the medicament container at the other end thereof, a drive unit comprising a plunger rod and plunger drive means, the plunger drive means being slidable arranged in relation to the plunger rod, being rotationally locked to the plunger rod and being rotatable in relation to the housing, said drive unit further comprising a first energy accumulating member arranged in the interior of the housing of the injection device and adapted to accumulate and store energy, wherein said plunger drive means is operationally associated with said first energy accumulating member, wherein the plunger drive means is releasable such that due to an output torque from said first energy accumulating member, the plunger drive means are allowed to be rotated and the plunger rod is urged towards the proximal end of the injection device whereby an injection is performed, and a rotary injection indication mechanism configured for indicating to the user the progress of the injection, wherein the rotary injection indication mechanism comprises a signalling member and a drive mechanism for rotationally driving said signalling member, said signalling member being coupled to said drive mechanism, said drive mechanism being coupled to said plunger drive means at the distal end of said plunger drive means, said rotary injection indication mechanism being arranged such that the progress of injection is shown through at least one opening provided at least in a distal end surface of the housing.

Injection device

A needle cover assembly includes a manually operable member; a rigid needle shield (RNS) provided with an internally arranged resilient cap, in turn arranged to house and protect an injection needle; and a RNS remover assembly including a tubular shaped member surrounding the RNS, in which the tubular shaped member is arranged with at least one grip member capable of gripping the RNS in order to remove the RNS. The RNS remover assembly further includes a spinning attachment member having a distal end fixedly attached to the tubular shaped member and a proximal end rotatably attached to the manually operable member such that the manually operable member can be freely turned in relation to the RNS remover assembly but is locked in an axial direction.

Needle cover assembly

The present disclosure relates to a safety mechanism for a medicament delivery device for mechanical shock absorption, which safety mechanism has a medicament delivery member sleeve, a housing having a proximal opening arranged to receive the medicament delivery member sleeve, wherein the medicament delivery member sleeve is axially displaceable inside the housing, between an extended position in which a proximal end portion of the medicament delivery member sleeve extends proximally from the housing and a retracted position in which the proximal end portion is received by the housing, wherein the proximal end portion has a resilient structure, enabling compression of the proximal end portion in the distal direction upon impact of an axial force greater than a threshold value.

Safety mechanism for a medicament delivery device and a medicament delivery device comprising the same

A medicament delivery device includes a housing having a longitudinal axis, a container holder, an axially movable plunger adapted to be displaced along the longitudinal axis into the container holder, and an energy accumulating member arranged inside the housing and adapted for displacing the plunger along the longitudinal axis. The plunger includes an outer plunger rod and an inner plunger rod arranged at least partially inside the outer plunger rod, the inner plunger rod being threadedly engaged with the outer plunger rod and manually rotatable to displace the inner plunger rod along the longitudinal axis into the container holder.

Medicament delivery device

A safety arrangement for being used in a medicament delivery device, comprising a container holder with a body section and a flange seat and a shell. The container holder is arranged to receive a container with a longitudinal body at one end passing over into a distal flange and at an opposite end passing over into a proximal orifice via a shoulder, such that the distal flanges of the container contacts the flange seat of the container holder. Moreover, the container holder is arranged in the shell such that the container holder is movable in a proximal direction in relation to the shell. A blocking element is arranged between the shell and the container holder. A blocking initiating structure is arranged to reposition the blocking element when the container holder is moved in the proximal direction in relation to the shell from a first position to a second position.

Safety arrangement and medical delivery device

The present disclosure relates to a safety mechanism () for a medicament delivery device for preventing activation thereof in the event of mechanical shock. The safety mechanism () comprises a medicament delivery member sleeve (), a proximal flange () provided at the proximal end of the medicament delivery member sleeve (), which proximal flange () has a first radially flexible arm () extending longitudinally in the distal direction, a housing () having a central proximal opening () arranged to receive a distal portion of the medicament delivery member sleeve (), wherein the medicament delivery member sleeve () is axially displaceable inside the housing () from an extended position to a retracted position relative to the housing (), and a cover () having a distal opening () forming a channel arranged to receive the medicament delivery member sleeve () and the housing (). The housing () has a proximal portion () arranged between the first radially flexible arm () and the outer surface of the medicament delivery member sleeve () when the medicament delivery member sleeve () is displaced from the extended position towards the retracted position. The channel is dimensioned such that, when the housing () is received by the cover (), there is a radial distance between the inner surface of the cover () and the outer surface of the proximal portion () which is less than a radial dimension of the first radially flexible arm (), preventing the medicament delivery member sleeve () from obtaining its retracted position.

A medicament delivery device has a drive mechanism that includes a first resilient member and a delay plunger rod assembly that includes a proximal plunger, a distal plunger, a chamber formed between the proximal and the distal plungers, an aperture, and a delay device in the chamber. The distal plunger is positioned and configured in relation to a hold and release mechanism such that, as the drive mechanism exerts a pressure on the medicament container, the distal plunger acts against the delay device, delaying a release of a signal generating member after a release of the drive mechanism to allow remaining contents of medicament in a medicament container to be completely expelled before the signal generating member is released.
