A drug delivery device includes a compartment sized to receive a cartridge. The compartment includes a cartridge bay that opens so that a cartridge may be inserted into the cartridge bay and that closes when the cartridge is received by the compartment. The drug delivery device also includes a housing including an expanding assembly. The expanding assembly includes a driver supported from a distal end by a linear stabilizer that includes a bearing configured to push against the housing. The driver is rotated by a motor. The expanding assembly also includes two mid screws threadedly connected to the driver, a plunger driver threadedly connected to the two mid screws, and an anti-rotational guide that prevents rotation of the plunger driver.

Described is an injection device (1) for administering a drug, the injection device (1) comprising a cartridge holder (2) adapted to receive a drug cartridge (3), a hollow injection needle (6) having a proximal tip (6.2) adapted to pierce a septum (4) of the cartridge (3) so as to establish a fluid communication between the cartridge (3) and the needle (6),and a cap (7) arrangeable over the cartridge holder (2) in a manner to cover the needle (6). In an initial state the cartridge (3) is arranged within the cartridge holder (2) with the septum (4) axially spaced from the proximal tip (6.2) of the needle (6). The cap (7) is adapted to move the needle (6) relative to the septum (4) for piercing it on movement of the cap (7) relative to the cartridge holder (2).

An injection device for dispensing a product, the injection device including a moveable element which is moved for a dispensing operation, a spring, a product container holder and a product container, wherein the spring pushes against the moveable element to move the moveable element to an initial position after the dispensing operation has ended and against the product container to seat the product container in the product container holder.

The present invention relates to drug delivery device and a and method of manufacturing a drug delivery device with a housing having a proximal end and a distal end, a cartridge adapted to accommodate a drug, a cartridge retaining member adapted to retain the cartridge, the cartridge retaining member being secured to the housing, and a spring washer being arranged within the housing so as to exerting a force on the cartridge and securing the cartridge against movement with respect to the cartridge retaining member and against movement with respect to the housing.

A liquid medicament administration device includes a body configured to contain and support a medicament container. The body includes an aperture. The aperture includes a viewing window that is coincident with the medicament container when the medicament container is present. The device is configured such that the viewing window is size-adjustable. Also disclosed are associated methods of manufacture.

A compact mechanical pump is provided. The pump is adjustable between a compact form and an expanded form, where the pump can be reduced to a compact form for ease of portability and storage and to the expanded form for use as a pump.

A medicament delivery device is presented having an elongated housing extending in a longitudinal direction, which housing is arranged to accommodate a medicament container, an end cap arranged with a first attachment element designed to engage with a second attachment element on the housing for attaching the end cap to the housing, a rotator rotatably arranged inside the housing, an activator axially slidable with respect to the housing from an extended position to a retracted position and operably connected to the rotator such as to rotate the rotator from an initial non-activated rotational position and an activated rotational position when the activator is moved from the extended to the retracted position. The rotator further comprises a blocking element arranged to cooperate with the first attachment element for preventing disengagement of the first attachment element from the second attachment element when the rotator is in the activated rotational position.

A drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a housing, a dose setting element rotatable relative to the housing during dose setting and dose dispensing, a drive member coupled to the dose setting member via a clutch, and a piston rod coupled to the housing and to the drive member. Further, the device further comprises a cartridge holder removably attached to the housing and a reset element, which is axially constrained to the dose setting element, and at least one spring acting on the reset element, such that, if the cartridge holder is detached from the housing, the reset element is axially moved relative to the housing onto a position in which the dose setting element is rotationally constrained to the housing and the drive member is allowed to rotate relative to the housing.

The present disclosure may provide an anti-loosening fixing structure for a bottle body of a flanging bottle. The anti-loosening fixing structure for the bottle body of the flanging bottle may comprise a fixing body, the bottle body being installed in the fixing body, and an upper end of the bottle body being arranged with a flange structure, wherein the top end of the fixing body may be arranged with a limiting ring, the limiting ring may be arranged with side limiting components that are arranged in a mirror distribution, an elastic support structure may be arranged in the storage space of the upper end of the bottle body, the upper end of the fixing body may be arranged with a guiding cycle, the guiding cycle may be arranged with upper end limiting components that are arranged in the mirror distribution.

The disclosure relates to an automatic medical injection device including a flexible reservoir prefilled with a medical solution. The reservoir includes a needle for injecting the medical solution into a patient's body, and a body removably enclosing the reservoir. The body includes a lower surface adapted to be applied against the patient's skin during an injection of the medical solution, said lower surface including a throughhole adapted for the passage of the needle, and an upper surface opposite to the lower surface, a compression device configured for compressing the reservoir to expel the medical solution through the needle, and an activation button configured to trigger the compression device upon activation by a user.
