Abstract
Ambulatory infusion pumps, durable assemblies, and disposable assemblies, including energy sources, reservoirs, baseplates, and related components therefor, as well as component combinations and related methods.
Claims16
A disposable assembly, comprising:
- a baseplate;
- a medicament reservoir on the baseplate;
- a plunger moveable within the reservoir;
- a motor rotor included in the disposable assembly, the motor rotor configured to rotate based on electromagnetic energy received from outside the disposable assembly;
- and
- a gear train entirely included in the disposable assembly, the gear train configured to transform rotation of the motor rotor into mechanical forces that move the plunger.
An infusion pump disposable assembly for use with an infusion pump durable assembly, the infusion pump durable assembly including a motor coil comprising coil windings, the infusion pump disposable assembly comprising:
- a baseplate;
- a motor rotor included in the infusion pump disposable assembly, the motor rotor defining an axis of rotation that is perpendicular to the baseplate;
- and
- a gear train entirely included in the infusion pump disposable assembly, the gear train configured to transform rotation of the motor rotor into linear movement;
- wherein the baseplate is configured to be mounted adjacent to the infusion pump durable assembly in such a manner that energization of the motor coil causes the motor rotor to rotate without direct mechanical coupling or electrical connection.
An infusion pump disposable assembly for use with an infusion pump durable assembly, the infusion pump durable assembly including a motor coil comprising coil windings, the infusion pump disposable assembly comprising:
- a baseplate;
- a motor rotor included in the infusion pump disposable assembly, the motor rotor defining an axis of rotation that is perpendicular to the baseplate and configured to rotate, when the baseplate is mounted adjacent to the infusion pump durable assembly, in response to energization of the motor coil without direct mechanical coupling or electrical connection;
- and
- means, entirely included in the infusion pump disposable assembly and operably connected to the motor rotor, for driving a plunger located within a medicament reservoir in response to rotation of the motor rotor.
A method comprising the step of:
- mounting a disposable assembly, including a baseplate, a motor rotor included in the disposable assembly and defining an axis of rotation that is perpendicular to the baseplate, and a gear train entirely included in the disposable assembly and configured to transform rotation of the motor rotor into linear movement, to a durable assembly, including an energy supply, a motor coil comprising coil windings, and a processor configured to control power to the motor coil, in such a manner that energization of the motor coil causes the motor rotor to rotate without direct mechanical coupling or electrical connection.
