Abstract
A fluid delivery device comprises a drive unit including an actuator and one or more first features and a cartridge filled with a fluid prior to being inserted into the housing. The cartridge having a fluid reservoir sealed at one end by a movable piston and sealed at another end by a pierceable septum. The cartridge includes one or more second features that are configured to align and mate with the one or more first features allowing the cartridge to be inserted into the drive unit. The piston is moveable by the actuator once the cartridge is inserted into the drive unit.
Claims29
A fluid delivery device comprising:
- a drive unit including a housing, an actuator, and one or more first features;
- and
- a cartridge comprising a longitudinal axis, wherein the cartridge is filled with a fluid prior to being inserted into the housing, the cartridge having a fluid reservoir sealed at one, first end by a piston and sealed at another, second end by a pierceable septum, the cartridge including or having secured thereto, one or more second features that project radially inwardly or outwardly relative to the longitudinal axis of the cartridge, extend around a circumference of the cartridge, the piston being moveable relative to the cartridge by the actuator once the cartridge is inserted into the drive unit,
- wherein, when the cartridge is positioned within the housing the one or more first features of the drive unit are mated with the one or more second features of the cartridge such that the cartridge is translatable relative to the drive unit in a direction perpendicular to the longitudinal axis and prevented from translating relative to the drive unit in a direction parallel to the longitudinal axis.
1 more element
A cartridge for insertion in a fluid delivery device, the cartridge comprising:
- a longitudinal axis;
- a reservoir filled with a fluid, the reservoir sealed at one, first end by a movable piston and sealed at another, second end by a pierceable septum;
- and
- one or more radial projecting and circumferentially extending keyed features configured to align and mate with one or more corresponding keyed features of the fluid delivery device allowing the cartridge to be inserted into the fluid delivery device and, while mated with the one or more corresponding keyed features of the fluid delivery device, prevent translation of the cartridge in a direction along the longitudinal axis and permit translation of the cartridge in a direction perpendicular to the longitudinal axis,
- wherein the cartridge is configured to be inserted into the fluid delivery device about a direction which is perpendicular to the longitudinal axis of the cartridge.
2 more elements
A fluid delivery device comprising:
- a drive unit including a housing, an actuator, and one or more first features;
- and
- a cartridge comprising a longitudinal axis, wherein the cartridge is filled with a fluid prior to being inserted into the housing about a direction which is perpendicular to the longitudinal axis of the cartridge, the cartridge having a fluid reservoir sealed at one end by a movable piston and sealed at another end by a pierceable septum, the piston being moveable by the actuator once the cartridge is inserted into the drive unit,
- wherein the fluid delivery device includes a door coupled to the housing, the door being rotatable relative to the housing to cover the cartridge and seat the cartridge into position within the drive unit, and
- wherein, when the cartridge is positioned within the housing the one or more first features of the drive unit are mated with one or more second features of the cartridge such that the cartridge is translatable relative to the drive unit in a direction perpendicular to the longitudinal axis and prevented from translating relative to the drive unit in a direction parallel to the longitudinal axis.

- wherein the cartridge includes a cover structure configured to be generally flush with the housing when the cartridge is fully inserted into the drive unit, and
- wherein, when the cartridge is positioned within the housing the one or more first features of the drive unit are mated with one or more second features of the cartridge such that the cartridge is translatable relative to the drive unit in a direction perpendicular to the longitudinal axis and prevented from translating relative to the drive unit in a direction parallel to the longitudinal axis.
