摘要：
An intravenous delivery system (100) may have a liquid source (102) containing a liquid (122), tubing (106), and an anti-run-dry membrane (136, 320, 420, 720) positioned such that the liquid (122), flowing form the liquid source (102) to the tubing (106), passes through the anti-run-dry membrane (136, 320, 420, 720). The anti-run-dry membrane (136, 320, 420, 720) may be positioned within an exterior wall (133, 310, 410, 710, 1110) of a drip unit (134, 300, 400, 700, 1100), and may have a weld surface (346, 446, 746) secured to a seat (334, 434, 734, 1134) of the exterior wall (133, 310, 410, 710, 1110) via application of compression to press the weld surface (346, 446, 746) against the seat (334, 434, 734, 1134), and application of coherent light (352) or vibration. In response to application of the coherent light (352) or vibration, localized melting may occur, causing the weld surface (346, 446, 746) to adhere to the seat (334, 434, 734, 1134). The anti-run-dry membrane (136, 320, 420, 720) may be modified to have a melting point close to that of the seat (334, 434, 734, 1134). Ultrasonic or laser welding may be applied in a manner that causes portions of the seat (334, 434, 734, 1134) to melt and flow into pores (138) of the weld surface (346, 446, 746).
