Abstract: The present invention discloses a functional powder delivery device for precise locating and quantifying when delivering the functional powder to a site in need in a patient. Meanwhile, the device avoids negative pressure effect in the output catheter when airflow is switched, and thus prevents pollution or jam in the output catheter due to splash or back flow of body fluid. The device ensures tube clearance of the output catheter by maintaining continuous airflow, and a special design of airflow switch allows switching to airflow of large volume to carry the powder when required. Through continuous positive airflow in the tube system, the functional powder can be delivered to the site in need by a continuous powder flow, which overcomes drawbacks of the delivery devices in prior arts. In addition, the design of foot pedal can help endoscopist for a solo operation. The serial connecting parts can adapt for various size of bottles of various types of functional powder.
