Laser welding device for connecting two flexible tube ends

摘要

A device (10) that provides a connection between two flexible tube ends, the device comprising a laser unit (200) having a laser beam; a laser optics assembly capable of changing a direction of the laser beam so that the laser beam strikes the tube ends, wherein the laser optics assembly includes (i) a prism (206) movably mounted between the two tube ends and (ii) a light pipe (220), the prism operable to reflect the laser beam to heat the tube ends, the light pipe operable to direct the laser beam to weld the tube ends together; and a pair of tube holders (70,72) each adapted to receive a one of the flexible tube ends and adapted to urge the two tube ends together after the two tube ends are aseptically heated via the laser beam, to join the heated tube ends together to form a weld.
