摘要

PROBLEM TO BE SOLVED: To provide a joint device for transfusion in a medical transfusion apparatus having no problem of toxicity to a human body, having excellent mechanical strength, and allowing an operator to easily, visually recognize a liquid flow.;SOLUTION: The joint device for transfusion in the medical transfusion apparatus, connects two or more transparent transfusion tubes for circulating liquid to be transfused, and controls the flow of the transfusion. The joint device for transfusion includes two or more transparent joining tubes 11 and 13 for connecting the two or more transparent transfusion tubes; a transparent connecting member 15 for connecting the two or more joining tubes at connection parts; and opening/closing valve means 17 disposed and formed at one or more connection parts. Connecting areas 19a and 19b generating heat by absorbing laser light, are formed at one connection parts of the respective joining tubes and the connecting member. In the connecting areas, the joining tubes 11 and 13 and the connecting member 15 are fused by laser.;COPYRIGHT: (C)2014,JPO&INPIT
