Abstract
A drug delivery device for delivering a medicament includes a housing arranged to contain a container, a receiver coil, and an energy storage unit. The receiver coil is arranged to receive energy from a transmitter coil by electromagnetic induction. The energy storage unit is arranged to be charged by at least a portion of the energy received by the receiver coil. At least a portion of the energy received by the receiver coil is converted to heat energy. The receiver coil is arranged in the drug delivery device to transfer the heat energy to the container to heat medicament contained in the container. A system comprising the drug delivery device is also disclosed.
Claims18
A drug delivery device for delivering a medicament, the drug delivery device comprising:
- a housing arranged to contain a container;
- a drive component arranged within the housing of the drug delivery device and configured to move a piston of the container to dispense medicament from the container during a medicament delivery process;
- and
- a receiver coil,
- wherein the receiver coil is arranged to receive energy by electromagnetic induction from a transmitter coil of an external device when the external device is brought into proximity with the drug delivery device during an induction process,
- wherein the drug delivery device is configured to perform the medicament delivery process while the external device is separated from the drug delivery device,
- wherein at least a portion of the energy received by the receiver coil is converted by the receiver coil itself to heat energy at the receiver coil, and
- wherein the receiver coil is arranged in the drug delivery device to transfer the heat energy to the container to heat medicament contained in the container.
A system comprising:
- a drug delivery device comprising:
- a housing arranged to contain a container;
- a drive component arranged within the housing of the drug delivery device and configured to move a piston of the container to dispense medicament from the container during a medicament delivery process;
- and
- a receiver coil,
- wherein the receiver coil is arranged to receive energy by electromagnetic induction from a transmitter coil of an external device when the external device is brought into proximity with the drug delivery device during an induction process,
- wherein the drug delivery device is configured to perform the medicament delivery process while the external device is separated from the drug delivery device,
- wherein at least a portion of the energy received by the receiver coil is converted by the receiver coil itself to heat energy at the receiver coil, and
- wherein the receiver coil is arranged in the drug delivery device to transfer the heat energy to the container to heat medicament contained in the container;
- and
- the external device for heating medicament contained in the drug delivery device using electromagnetic induction, the external device comprising:
- a driving circuit;
- and
- the transmitter coil,
- wherein the driving circuit is arranged to drive the transmitter coil,
- wherein the driving circuit and the transmitter coil are arranged to transmit energy to a receiver coil of the drug delivery device by electromagnetic induction, and
- wherein the receiver coil of the drug delivery device is arranged to receive the energy from the transmitter coil of the external device and to heat medicament contained in the drug delivery device.
