Latest Patent Applications

Ya-Wen Shih's notable patent application is titled "FUNCTIONAL POWDER DELIVERY DEVICE AND SYSTEM THEREOF." This invention discloses a functional powder delivery device designed for precise locating and quantifying when delivering functional powder to a site in need in a patient. The device effectively avoids negative pressure effects in the output catheter when airflow is switched, thus preventing pollution or jam in the output catheter due to splash or backflow of body fluid. It ensures tube clearance of the output catheter by maintaining continuous airflow. Additionally, a special design of the airflow switch allows for 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, overcoming the drawbacks of prior art delivery devices. The design also includes a foot pedal to assist endoscopists in solo operations, and the serial connecting parts can adapt to various sizes of bottles containing different types of functional powder.

Conclusion

Ya-Wen Shih's contributions to the field of medical device innovation highlight her commitment to improving patient care through advanced technology. Her work in developing a functional powder delivery device showcases her inventive spirit and dedication to solving complex medical challenges.
