A modular drive train is selectively securable within a wearable injector. The drive train includes a chassis and a telescoping driving assembly mounted within the chassis. The driving assembly includes a first shaft rotatable relative to the chassis, and a second shaft connected with the first shaft and axially movable relative thereto. Rotation of the first shaft axially drives the second shaft. The chassis includes one of a bearing and an elastically expandable collar projecting axially forward into the chassis from a rear end thereof, and the first shaft includes the other of the bearing and the elastically expandable collar projecting axially rearwardly from a rear end thereof. The collar is configured to elastically snap over an interference element of the bearing, whereby engagement of the collar with the bearing axially secures the first shaft to the chassis and permits rotation of the first shaft about the bearing.

A syringe holder for facilitating dispensing of medication to a patient from a syringe. The syringe holder includes a cylindrical housing configured to be attached to a barrel portion of the syringe. A first visual dosing aid on a surface of the cylindrical housing is of a first color and has a plurality of first dosing segments where the first color is correlated to a first patient size. Each of the first dosing segments identifies a volume of the medication corresponding to a first medication dose. A second visual dosing aid on a surface of the cylindrical housing is of a second color and has a plurality of second dosing segments where the second color is correlated to a second patient size. Each of the second dosing segments identifies a volume of the medication corresponding to a second medication dose.

The present invention relates to a shell assembly for a medicament delivery device, which shell assembly comprises at least one first shell section provided with an entry passage and designed such that at least a major part of a medicament delivery device entered through said entry passage is accommodated inside said at least one first shell section, a closure element operably arranged to said at least one first shell section for closing said entry passage, and fixation elements arranged for fixating said medicament delivery device in relation to said at least one first shell section and said closure element.

The invention relates to an automatic injector device comprising a single-use, disposable, drug delivery assembly comprising a housing and a syringe assembly located at least partially within the housing, said syringe assembly including a plunger, a pre-filled unit-dose drug containing chamber, and needle, said plunger, drug containing chamber and needle being configured and dimensioned to function as an injection syringe; a reusable motorized transmission assembly comprising a housing, a motor and transmission assembly located within the housing, said transmission assembly being configured and dimensioned to engage the plunger of said syringe in the drug delivery assembly and expel said unit dose dmg from the drug containing chamber, into the needle and out of the drug delivery assembly; said single-use disposable drug delivery assembly and said reusable motorized transmission assembly are in substantial axial alignment along a longitudinal axis defined by the syringe, plunger, pre-filled unit-dose drug containing chamber, and needle.

An information collection method for an injection pen includes several steps as follows. The action of the pressing knob is sensed to determine whether the rotation information of the pressing knob is obtained. The traveling movement of the injection pen is sensed to determine whether the movement information of the injection pen is obtained. A determination is made that the traveling movement of the injection pen is conformed as an intending injection action according to the rotation information of the pressing knob and the movement information of the injection pen. When the traveling movement of the injection pen is conformed as the intending injection action, an actual injection dose that the injection content is pushed outwards from the injection pen is calculated according to the rotation information of the pressing knob. The actual injection dose is recorded.

The present invention relates to a shell assembly for a medicament delivery device, which shell assembly comprises at least one first shell section provided with an entry passage and designed such that at least a major part of a medicament delivery device entered through said entry passage is accommodated inside said at least one first shell section, a closure element operably arranged to said at least one first shell section for closing said entry passage, and fixation elements arranged for fixating said medicament delivery device in relation to said at least one first shell section and said closure element.

An apparatus is disclosed, comprising a detector unit comprising a detector configured to detect an actuation action performable via the detector unit to an actuation button of a medical device to cause the medical device to eject at least a portion of a medicament comprised in the medical device. The detector is configured to detect the actuation action based on a detection of a force and/or a touch applied to the detector unit as part of the actuation action. The apparatus further comprises an electric unit connected to the detector and configured to store and/or provide information related to the detected actuation action. Furthermore, an according method and a computer program for controlling this method are disclosed.

The shell is intended to receive an injection system comprising a syringe received in a safety device which has: a body receiving the syringe; a shield movable relative to the body, for covering a needle; finger flanges extending outwardly. The shell comprises a tubular housing receiving a distal portion of the safety device and a casing receiving the finger flange, and further comprising: several snap features which flex outwardly during insertion of the finger flange in the casing, the finger flange being inserted distally from a distal face of the snap feature in the mounted position; and a protrusion located distally from each distal face, which exerts an inward biasing force on the finger flange in the mounted position.

A medication administering device, to which a preparation syringe containing a preparation is mounted, and which administers a preparation to a living body, and comprises a main body; a cylindrical syringe holder that is provided to the main body and into which the preparation syringe is inserted from the rear end side; a cylindrical syringe cover that supports the preparation syringe on the inner peripheral face side, and into which the preparation syringe is inserted from the distal end side; an inner case that guides the syringe cover and is removably fitted together with the syringe cover; and a distal end cap that guides the main body and is removably fitted together with the main body, and moves in conjunction with the syringe cover during attachment to the main body.

An auto-injector for hypodermic delivery of medication includes a first subassembly releasably coupled to a second subassembly. The first subassembly includes a cartridge holder configured to receive a medication cartridge, an injection needle through which medication can pass from the medication cartridge, and a needle shield movable between an extended position enclosing the needle and a retracted position in which a proximal end of the needle is not enclosed by the needle shield. The second subassembly includes a movable plunger rod positioned within a housing. Movement of the needle shield in a proximal direction from the retracted position to the extended position following administration of the medication automatically releases the first subassembly from the second subassembly. The released first subassembly is locked with the needle shield in the extended position. A new first subassembly containing an unused dosage of medication may be inserted and releasably connected to the second subassembly.
