Abstract: Provided is a blood component separation device that can shorten the overall time to collect high-concentration platelet liquid for blood component donation, thereby reducing time to keep a donor for blood drawing. The blood component separation device includes a temporary storage bag (also used as a buffy coat bag) which is also used as a whole blood bag for storing whole blood drawn from the donor. A control means performs whole blood drawing from the donor in parallel with performing at least either of a circulation flow step and an acceleration step, thereby storing the collected whole blood in the temporary storage bag.

Abstract: An information search apparatus is provided. The information search apparatus includes: a character string input unit configured to obtain a character string from a client; a character string information search unit configured to obtain information that includes the character string from an index DB; a similarity calculation unit configured to calculate degree of similarity between the character string and searched information; and an output unit configured to output the searched information in descending order of the degree of similarity.

Abstract: A protector includes a supporting member mounted on a needle assembly having a needle main body; an outer cover member arranged to incline to the needle main body by having an arm axially supported to the supporting member; and an inner cover member arranged inside the outer cover member. The outer cover member has a cylindrical body having a needle slit extending in an axial direction for insertion of the needle main body. The inner cover member has an arcuate column, which interlocks with the needle assembly when the outer cover member inclines to insert the needle main body into the needle slit, and rotates by sliding on the inner surface of the cylindrical body. The arcuate column has a circular arc cross-section with an area facing at least the needle slit opened to the cylindrical body at an opened position, the needle slit being covered at a closed position.
