Implantable manually-controllable drug delivery apparatus

An implantable manual control drug delivery device comprising:

• a drug storage configured to be filled with and store a drug;
• a drug release actuator configured to release the drug of the drug storage in predetermined amounts to the outside of the device through movement of a manual control button;
• and
• a housing in which the drug storage and the drug release actuator are stacked and which constitutes an external form of the device,
• wherein a drug injection port and a drug delivery port are formed in a space of the housing in which the drug storage is stacked,
• a space of the housing in which the drug release actuator is stacked includes an actuator space which includes an opening for vertical movement of a spring actuator configured to pump the drug and a drug chamber space which is configured to be filled with a predetermined amount of the drug as the drug is pumped and then release the drug,
• the drug release actuator includes an inlet valve configured to connect the drug storage and the drug chamber space, a drug chamber connected to one end of the inlet valve, an outlet valve configured to connect the drug chamber and a drug discharge port, and the spring actuator connected to the manual control button and configured to apply a pressure to the drug chamber, and
• due to the movement of the manual control button, the spring actuator releases a drug of the drug chamber to the outside of the device through the outlet valve and the drug discharge port and fills the drug chamber with the drug of the drug storage through the inlet valve.
