<p>PURPOSE: To take blood out of a bag and to inject it again by providing a bag device with crossing arms for fixture attachably and detachably arranged on both the end faces of the bag and a frame member integrally coupled outside the bag and detaching the arms for fixture from the frame when this bag is filled with blood as a whole. CONSTITUTION: Around a flexible bag 1, there are four frame members 6 arranged at the angle intervals of 90 deg.. When arms 7 and 7' for fixture composed of four members are fitted and connected to opening parts 9 of the frame members 6 at both the terminal parts of the bag 1 by pins 8, the flexible bag 1 is kept expanded. When it is desired to reduce the volume of the bag 1, it is enough for the crossing arms 7 and 7' for fixture only to cancel fitting and connecting with the frame members 6 for deforming the film wall of the bag. In case of use, the bag is suitably supported conveniently near a patient and besides, the outside terminal part of a lead-in tube 2 is arranged at a position where surgical treatment is performed.</p> |
