Abstract
A system for inserting a pharmaceutical cartridge into a delivery device is described. The cartridge can be inserted in an arbitrary orientation and the system reorients the cartridge to a locked orientation. For example, a driver applies a torque to the cartridge to cause the reorienting. The torque rotates the cartridge around an axis thereof until the cartridge reaches the locked orientation. When the cartridge reaches the locked orientation, an interference element on the cartridge interlocks with a complementary interference element on the delivery device to lock the cartridge in the locked orientation. Once the cartridge is locked in the second orientation, the torque causes discharge the pharmaceutical.
Claims17
A method of loading a cartridge having a cylindrical reservoir into a delivery device, the method comprising:
- inserting the cartridge into a cartridge bay of the delivery device in a first rotational orientation about a longitudinal axis of the cartridge thereby longitudinally displacing a first interference element of the delivery device;
- powering a motor of the delivery device to apply a torque to the cartridge to rotate the cartridge to a second rotational orientation about the longitudinal axis of the cartridge;
- and
- interlocking a second interference element of the cartridge with the first interference element on the delivery device to lock the cartridge in the second rotational orientation.
A method of discharging a pharmaceutical from a cartridge using a delivery device, the method comprising:
- inserting the cartridge longitudinally into a cartridge bay of the delivery device in a first rotational orientation about a longitudinal axis of the cartridge thereby longitudinally displacing a first interference element of the delivery device;
- applying a torque to the cartridge with a driver of the delivery device to rotate the cartridge to a second rotational orientation about the longitudinal axis of the cartridge;
- interlocking a second interference element of the cartridge with the first interference element on the delivery device to lock the cartridge in the second rotational orientation;
- and
- continuing to apply torque to the cartridge with the driver of the delivery device to discharge the pharmaceutical from the cartridge.
