Abstract

Described is a medicament cartridge comprising a housing having open proximal and distal ends, a first coupling mechanism, and a syringe slidably disposed in the housing. The syringe includes a needle and has a retracted position in which the needle is covered by the housing and an extended position in which the needle is exposed. A delivery device comprises the medicament cartridge, an actuator comprising a plunger, a motor adapted to translate the plunger, a second coupling mechanism adapted to detachably engage the first coupling mechanism, and a control button adapted to actuate the motor. A carrier comprises a first slot for at least partially containing the actuator, a second slot for at least partially containing the medicament cartridge, a user interface adapted to provide at least one a visual signal and an audible signal.

First claim

The invention claimed is:

1. A delivery device comprising:
a medicament cartridge comprising
a housing having open proximal and distal ends,
a syringe slidably disposed in the housing, the syringe containing a medicament and including a needle, the syringe having a retracted position in which the needle is covered by the housing and an extended position in which the needle is exposed for needle insertion, and
a first coupling mechanism; and

an actuator, the actuator comprising
a plunger,
a motor adapted to translate the plunger, wherein translation of the plunger in a first axial direction pushes the syringe from the retracted position to the extended position,
a second coupling mechanism adapted to detachably engage the first coupling mechanism such that the housing of the cartridge containing the syringe is detachably engaged to the actuator, and
a control button adapted to actuate the motor to axially translate the syringe of the cartridge relative to the housing of the cartridge for needle insertion.

2. The delivery device according to claim 1 , wherein when the syringe is in the extended position, translation of the plunger in the first axial direction pushes a stopper in the syringe.

3. The delivery device according to claim 1 , wherein the actuator further comprises an energy source.

4. The delivery device according to claim 1 , wherein the control button of the actuator is adapted to actuate the motor of the actuator to
axially translate the syringe of the cartridge relative to the housing of the cartridge for needle insertion, and
apply a force on a stopper of the syringe for medicament delivery.

5. A system comprising:
a medicament cartridge comprising
a housing having open proximal and distal ends,
a syringe slidably disposed in the housing, the syringe containing a medicament and including a needle, the syringe having a retracted position in which the needle is covered by the housing and an extended position in which the needle is exposed for needle insertion, and
a first coupling mechanism;

an actuator comprising
a plunger,
a motor adapted to translate the plunger,
a second coupling mechanism adapted to detachably engage the first coupling mechanism such that the housing of the cartridge containing the syringe is detachably engaged to the actuator, and
a control button adapted to actuate the motor to axially translate the syringe of the cartridge relative to the housing of the cartridge for needle insertion; and

a carrier comprising
a first slot for at least partially containing the actuator;
a second slot for at least partially containing the medicament cartridge; and
a user interface adapted to provide at least one a visual signal and an audible signal, wherein the user interface includes at least one of a display screen, a light emitting diode, a speaker, a microphone, a button, and a dial, and

wherein the medicament cartridge and the actuator are removable from the carrier and, when removed from the carrier, adapted to be coupled to each other to form a delivery device.

6. The system according to claim 5 , wherein the carrier further comprises a first energy source including a disposable battery, a rechargeable battery or a connector adapted to couple to an external power source.

7. The system according to claim 5 , wherein the carrier further comprises a drug tempering unit adapted to heat or cool the cartridge.

8. The system according to claim 5 , wherein the carrier further comprises a temperature sensor adapted to sense a temperature of the cartridge.

9. The system according to claim 5 , wherein the carrier further comprises a first communication device adapted to communicate with a second communication device in the actuator.

10. The system according to claim 5 , wherein the visual signal includes at least one of alphanumeric or graphical data on the display screen and a change in color or illumination sequence of the light emitting diode, and the audible signal includes at least one a tone, an instruction, and a message regarding progress of an injection.

11. The system according to claim 5 , wherein the control button of the actuator is adapted to actuate the motor of the actuator to
axially translate the syringe of the cartridge relative to the housing of the cartridge for needle insertion, and
apply a force on a stopper of the syringe for medicament delivery.
