Piston Actuator Module for Controlled Aerosol Dosing

The piston automatically performs the dispensing function by being forced into the vial, eliminating the need for manual patient operation. The system self-regulates to deliver the complete liquid dose through the defined flow path, ensuring maximum substance delivery while maintaining dose control through the controlled flow path design.

The invention extracts the dispensing action from manual patient operation and transfers it to an automated piston mechanism. By removing the manual intervention element, the system eliminates inconsistencies in dispensing while maintaining the sealed vial structure for dose control.

The piston mechanism automatically performs the dispensing function without requiring precise patient manipulation. The system self-regulates through the forced piston movement into the vial, ensuring consistent and reliable dispensing while requiring minimal patient intervention (simply activating the cam mechanism).

The invention replaces the manual mechanical operation by the patient with an automated cam-and-piston mechanical system. This substitution maintains ease of use (simple cam activation) while eliminating the inconsistencies of manual operation through the controlled mechanical piston movement.

The system establishes a defined flow path and sealed environment before substance dispensing begins. The vial is sealed until the moment of use, and the piston creates a controlled flow path that prevents contamination during the dispensing process, allowing complete substance displacement without increasing contamination risk.

The invention introduces a controlled flow path as an intermediary between the sealed vial and the external environment. This intermediate channel allows complete substance displacement while maintaining separation from contamination sources, as the flow path is defined and controlled throughout the dispensing process.
