    • 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).

    • Un método para fabricar una unidad de goteo (134) para un sistema de administración intravenosa (100), comprendiendo el método: proporcionar una pared exterior conformada para definir al menos parcialmente una cámara de goteo capaz de recibir un líquido de una fuente de líquido (102), comprendiendo la pared exterior un asiento (334); proporcionar una membrana anti-paso en seco (136) que comprende una pluralidad de poros (138) que son permeables al líquido, en donde la membrana anti-paso en seco (136) está formada por un material hidrófilo configurado para resistir el paso de aire a través de los poros (138), comprendiendo la membrana anti-paso en seco (136) una superficie de soldadura (346); colocar la membrana anti-paso en seco (136) dentro de la cámara de goteo de manera que la superficie de soldadura (346) esté en contacto con el asiento (334); aplicar compresión para presionar la superficie de soldadura (346) contra el asiento (334); caracterizado por la aplicación de luz coherente en una pluralidad de caminos a al menos una de la membrana anti-paso en seco (136) y la pared exterior para producir la fusión localizada de al menos uno del asiento (334) y la superficie de soldadura (346), en donde los caminos se superponen para asegurar que se forme un sellado completo; y en respuesta a la fusión localizada, hacer que la superficie de soldadura (346) se adhiera al asiento (334).
