摘要： A needle shield remover for a wearable injector includes a first portion having a cam member, the first portion having a top surface and a bottom surface positioned opposite to the top surface, and a second portion connected to the first portion. The second portion having a top surface and a bottom surface positioned opposite to the top surface, with the second portion including a device connector configured to secure the second portion of the needle shield remover to the wearable injector. The first portion is moveable relative to the second portion between a first position where the cam member is aligned with the top surface of the second portion and a second position where the cam member protrude from the top surface of the second portion. The cam member is configured to contact a housing of the wearable injector when the first portion is in the second position.

摘要： An autoinjector includes a case adapted to hold a medicament container having a needle telescopically coupled to the case and movable between a first extended position relative to the case in which the needle is covered and a retracted position relative to the case in which the needle is exposed. The autoinjector includes a plunger rotationally and slidably disposed in the case rotatable relative to the case between a first rotational position in which the plunger is engaged to the case and a second rotational position in which the plunger disengages the case engages the plunger to rotate the plunger from the first rotational position to the second rotational position when the needle shroud translates from the first extended position to the retracted position. The autoinjector includes a cap removably coupled to the case includes at least one compliant case beam adapted to releasably engage at least one aperture in the case.

摘要： Drug delivery devices and related arrangements are disclosed. A drug delivery device may include a housing having an opening, a drug storage container including a delivery member with an insertion end configured to extend at least partially through the opening, and a plunger. A drive mechanism may be included for driving the plunger in a distal direction to expel a drug from the drug storage container through the delivery member upon activation. The drug delivery device may additionally include a guard moveably disposed adjacent to the opening and operably coupled to the drive mechanism for activation of the drive mechanism. A lock may be selectively engageable with the guard to limit movement of the guard in the proximal direction. An indicator may be coupled to the drive mechanism to generate an audible signal during drug delivery, and to cease generating the audible signal when drug delivery is complete.

摘要： An auto-injector for administering a dose of a liquid medicament includes an elongate housing arranged to contain a syringe with a hollow needle and a stopper for sealing the syringe and displacing the medicament, the housing having a distal end and a proximal end with an orifice intended to be applied against an injection site. The syringe is slidably arranged with respect to the housing. A spring capable of, upon activation: pushing the needle from a covered position inside the housing into an advanced position through the orifice and past the proximal end (P), operating the syringe to supply the dose of medicament (M), and retracting the syringe with the needle into the covered position. After delivering the medicament, an activator arranged to lock the spring in a pressurized state prior to manual operation and capable of, upon manual operation, releasing the spring for injection.

摘要： A method of manufacturing an autoinjector includes supplying a preloaded syringe including a sterile needle and a needle cover, a preassembled distal housing portion including an adhesive base on a distal end thereof and a channel for insertion of the preloaded syringe, and a proximal housing portion including a motor and a transmission. An activation device is supplied and the preloaded syringe is slid longitudinally through an opening in a proximal end of the distal housing portion into the channel. A distal end of the proximal housing portion is joined to a proximal end of the distal housing portion.

摘要： A medical injection system is provided. The medical injection system includes an injection initiation feedback module. The injection initiation feedback module includes an actuator and a click collar, which comprise an impact plate and a click surface, respectively. The click collar further includes a click surface protrusion to restrict the click surface from contacting the impact plate. The actuator further includes an impact plate groove to accommodate the click surface protrusion at the initiation of injection and the click surface contacts the impact plate to generate an injection initiation feedback prompt.

摘要： A cartridge for positioning within a pharmaceutical delivery device is described. The cartridge has a housing with a light pipe section which acts as a light pipe having an input location, and a light diffusing section optically coupled to the light pipe. The light diffusing section extends beyond a plane defined by the housing.

摘要： An injector device is configurable between a safe state and an operable state and comprises a housing having a distal end and a proximal end; a medicament cartridge disposed within the housing; a needle unit comprising a needle and being disposed in the distal end of the housing; a sleeve displaceable along a longitudinal axis of the device between a first position in which the sleeve conceals the needle and a second position in which the needle is exposed from an end of the sleeve; a locking mechanism configured to prevent displacement of the sleeve when the device is in the safe state; and a button disposed in the proximal end of the housing, the button being configured to switch the device between the safe state and the operable state by releasing the locking mechanism when the button is pressed from an initial position into a depressed position during use.
