Abstract
An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may have a weld surface secured to a seat of the exterior wall via application of compression to press the weld surface against the seat, and application of coherent light or vibration. In response to application of the coherent light or vibration, localized melting may occur, causing the weld surface to adhere to the seat. The anti-run-dry membrane may be modified to have a melting point close to that of the seat. Ultrasonic or laser welding may be applied in a manner that causes portions of the seat to melt and flow into pores of the weld surface.
