  • Publication number: 20110015737
    Abstract: An adhesion-preventive film is provided that is excellent in flexibility and can prevent cracks from occurring. The adhesion-preventive film contains a copolymer of lactide and caprolactone. The lactide and the caprolactone of the copolymer has a mole ratio in the range of 65:35 to 80:20. Even when this adhesion-preventive film is used in a curved state in vivo or is wound around an affected part such as a tendon, for example, it can provide an adhesion-preventive function for a sufficiently long period without cracking.

  • Publication number: 20110004161
    Abstract: A rotator 2 is supported rotatably on a base 1, and a roller 7 is supported rotatably at the outer periphery of the rotator 2. A pressing member 4 has a circular arc pressing surface 4a and can be located selectively in a retracted position where a groove-shaped space 8 is formed between the pressing surface and the rotator and in a proximity position where the pressing surface is closer to the rotator. When the pressing member is in the retracted position, a pump tube can be inserted in the groove-shaped space. The pressing member is moved to the proximity position with the pump tube being held, and then the rotator is rotated, so that the pump tube is pressure-driven by the roller. The injection device with a simple structure easily can extract almost the entire semi-solidified nutritional supplement from a nutritional supplement container and inject it into a patient.

  • Patent number: 7842001
    Abstract: An automatic priming method in which an arterial-side chamber is maintained in a normal position during priming, as in a case of dialysis treatment, and in which forward and backward rotations of a blood pump are employed, and a speed of rotation, in particular, backward rotation, is adjusted to be low, so that air or the like is reliably prevented from entering a dialyzer. The priming method for use in a blood purification circuit in which priming is conducted by supplying physiological saline into a circulation circuit formed by connecting an arterial blood circuit with a venous blood circuit includes filling the venous blood circuit with a priming solution (physiological saline), discharging the priming solution for cleaning the arterial blood circuit, conducting a treatment in a direction opposite to the overflow step, which may be followed by a forward direction re-circulation step, and re-circulating in a forward direction.

  • Publication number: 20100249728
    Abstract: A medical container (1) includes a bag-like container body (10) made up of two flexible sheets (12a, 12b). At least one of a pair of long-side sealed areas (11La, 11Lb) formed by the two sheets being bonded together is provided with a sealed protruding portion (20a, 21a, 20b, 21b) protruding toward the other long-side sealed area such that the spacing between the pair of long-side sealed areas is locally narrowed. A crease (30a, 31a, 30b, 31b) passing through the sealed protruding portion is formed in the sheets when a liquid substance has been injected into the container body in a volume greater than or equal to 10% of a defined volume of the container body and the medical container is hung. Accordingly, it is possible to know the exact amount of a liquid substance in the container by using a scale provided on the sheets constituting the container even if a crease is formed in the sheets due to the liquid substance being in the container.
