    摘要： To provide a blood processing device, in which a blood processing member can secure an effective filtration area substantially two times greater than those of conventional ones and therefore it becomes possible to largely reduce the filtration time. [Solution] A first blood processing member 5U formed by stacking multiple non-woven fabrics each having a predetermined thickness and a second blood processing member 5D formed by stacking multiple non-woven fabrics each having a predetermined thickness are arranged in a first housing 2/U and a second housing 2/D, respectively. The first blood processing member 5U and the second blood processing member 5D are arranged in such a manner that inside filtration sections 5FI/U and 5FI/D face each other. A first blood chamber 2.1 is formed between the inside filtration sections 5FI/U and 5FI/D, and a second blood chamber 2.2 is formed between the inner periphery of the first housing 2/U and an outside filtration section 5FO/U of the first blood processing member 5/U and between the inner periphery of the second housing 2/D and an outside filtration section 5FO/D of the second blood processing member 5D. A blood inlet port 71 is formed so as to be communicated with the first blood chamber 2.1 (a blood inflow chamber 2IR), and a blood discharge port 7O is formed so as to be communicated with the second blood chamber 2.2 (a blood outflow chambers 20R/U and 20R/D).

    摘要： PROBLEM TO BE SOLVED: To provide an anti-adhesion material capable of producing an excellent anti-adhesion performance without impairing degradability, handleability, and contact properties in actual use.
    SOLUTION: An anti-adhesion material is provided that contains an ascorbic acid or anascorbic acid derivative as an antioxidant in a solid or semisolid base body made of a water-soluble polymer and a poly(aliphatic ester). Since the anti-adhesion material has the base body acting as a physical barrier inserted between the surfaces of a wound and the healing on the wound surfaces is promoted by the ascorbic acid or the derivative thereof being sustained-released, the anti-adhesion performance is extremely efficiently produced in a synergistic manner.

    摘要： Provided is a safety apparatus for medical needles which is free from accidental exposure of an acuate top end contaminated with a blood, etc. from a lower portion thereof. The safety apparatus includes a shield member (3) having a shield hub (35), a shield member connection hub (40H) and leg portions (31,32), the leg portions (31,32) being capable of extending from the first folded position to the second extended position, a needle (21) being to be inserted in the space (40S) of the above shield member connection hub (40H) when the leg portions (31,32) are in the first folded position, the wall (43DW) of the above slide-member (42) being to be pulled into the shield member connection hub (40H) when the leg portions (31,32) are extended up to the second extended position, whereby the apparatus is so formed that it can prevent the distal end (23) of the needle (21) from being exposed to an outside.
