Abstract
Disclosed are examples for a system for drug delivery and components thereof. The system may include an on-body pump device and a secondary unit. The on-body pump device may include a reservoir and a fluid pathway. The reservoir may be configured to hold a liquid drug. The secondary unit may be removably coupled to the on-body pump device. The secondary unit may be configured to receive a prefilled cartridge containing a liquid drug, expel the liquid drug from the prefilled cartridge, and deliver the liquid drug to the reservoir of the on-body pump device via the fluid pathway. Examples of variations to the secondary unit are also disclosed.
Claims12
A system, comprising:
- an on-body pump device comprising a reservoir and a fluid pathway, wherein the reservoir is configured to hold fluid;
- and
- a secondary unit removably coupled to the on-body pump device and including a fill needle, a cartridge stop, and an opening;
- and a prefilled cartridge containing:
- a liquid drug;
- and
- a moveable plunger movable within the prefilled cartridge, to expel the liquid drug from the prefilled cartridge into the fill needle through a movement of the movable plunger in the prefilled cartridge as the prefilled cartridge is inserted into the opening, wherein the secondary unit is configured to:
- deliver the liquid drug to the reservoir of the on-body pump device via the fill needle;
- and
- wherein the secondary unit further comprises a second needle and a needle insertion mechanism, wherein the second needle is coupled to the fluid pathway, and the needle insertion mechanism is operable to insert the second needle into skin of a user to enable delivery of the liquid drug.
A secondary unit, comprising:
- an opening configured to receive a prefilled cartridge containing a liquid drug, wherein a fill needle and a cartridge stop are within the opening a needle insertion mechanism configured to actuate an introducing needle device of an on-body pump device;
- and
- a settings dial configured to set or adjust an amount of the liquid drug for delivery into the on-body pump device,
- wherein the fill needle has one end configured to pierce a septum of the on-body pump device to deliver the liquid drug to the on-body pump device and another end configured to pierce a movable plunger of the prefilled cartridge, wherein the liquid drug is expellable from the prefilled cartridge into the fill needle as the prefilled cartridge is inserted into the opening through a movement of the movable plunger in the prefilled cartridge to deliver the liquid drug to a reservoir of the on-body pump device via the fill needle.
