A recently granted patent (Publication Number: US11730883B2) describes a medicament delivery device that includes a housing, a medicament chamber, a plunger, a pin, an actuation assembly, and a needle. The housing is designed to hold the components of the device, including the medicament chamber, plunger, and pin. The actuation assembly, which is detachably coupled to the housing, is responsible for moving the pin from a position that prevents movement of the plunger to a position that allows movement of the plunger. This movement occurs after a predetermined time delay, which is set by the actuation assembly.

The actuation assembly consists of an adapter, an activator, and a gear. The adapter is coupled to the pin and includes an internal opening to receive a portion of the pin. It also features a deflectable flange that engages a rim of the pin. The activator is responsible for moving the adapter from a first position to a second position, thereby moving the pin. The gear, which has an internal opening to receive the adapter, allows the adapter to move relative to it.

The medicament delivery device also includes additional features such as a drive gear, an engagement member, a biasing element, an actuator, a timer, an adhesive patch, and a communication module. The drive gear is coupled to the activator and meshes with the gear, allowing the activator to rotate the gear. The engagement member, when in the second position, allows the adapter to move from the first position to the second position. The biasing element urges the engagement member towards the second position. The actuator is responsible for moving the engagement member from the first position to the second position. The timer alerts the user when the device has been activated and when to remove it. The adhesive patch is used to attach the device to the user's skin. The communication module enables communication with a remote device.

The method of operating the medicament delivery device involves attaching the actuation assembly to the device, deploying the needle into the user's skin, and allowing the actuation assembly to move the pin from the first position to the second position after a pre-set time delay. The housing of the device can be coupled to an adhesive patch, which is then adhered to the user's skin.

Overall, this patent describes a medicament delivery device with various components and features that allow for controlled and timed delivery of a medicament, such as insulin, to a user. The device is designed to be single-use and includes mechanisms for activating the device, monitoring dosage, and communicating with external devices.
