Abstract: A low-force, non-displacement, micro/miniature valve and/or pump assembly is provided. A tube component having a first side port coupled to an inlet portion and a second side port coupled to an outlet portion can be selectively moved to alternatively couple the side ports to a first or second piston pump chamber. First and second pistons can be actuated after positioning the tube component to either draw in fluid or push out fluid from either the first or second piston pump chambers during each actuation of the pistons. The fluid can be drawn in from a reservoir and can be expelled to a patient for providing a dose of the fluid to the patient.

Abstract: An airflow generating device includes a container, a first air switch, a second air switch, a magnetic oscillating element, and one or more coils. The container has a first opening and a second opening. The first air switch is configured to open or close the first opening. The second air switch is configured to open or close the second opening. The magnetic oscillating element is disposed in the container. The one or more coils are disposed adjacent to the magnetic oscillating element. The one or more coils are configured to generate at least one sensing current corresponding to the oscillation of the magnetic oscillating element, so as to make the first air switch and the second air switch respectively open or close the first opening and the second opening according to the at least one sensing current.
