摘要： A compression device set according to the present disclosure includes a compression device configured to be adhered to a biological surface and to compress the biological surface in a state of being adhered to the biological surface; and a pre-compression member attached to the compression device and configured to compress, before the compression device is adhered, the biological surface to which the compression device is to be adhered. The compression device includes an adhesion surface configured to be adhered to the biological surface, and a compression portion configured to compress the biological surface in a compression region that is sandwiched by the adhesion surface or surrounded by the adhesion surface. The pre-compression member includes a protruding portion protruding from the adhesion surface of the compression device and configured to compress the biological surface before the adhesion surface is adhered to the biological surface in the compression region.

摘要： A transport container is configured to capture air bubbles remaining in a container with a simple mechanism and a simple operation to protect a graft. The transport container includes: a lid that seals a container for housing a graft, in which the lid has a protrusion protruding toward a space inside the container in a state of being attached to the container. A substantially annular groove is formed on a lower surface of the protrusion. Gas and liquid inside the container housing the graft and liquid are pushed out by the lid to achieve a liquid-tight state, and air bubbles in the liquid can be captured in the groove on the lower surface.

摘要： Provided is a means capable of measuring an analyte concentration with high accuracy without requiring fractionation of a biological component. The present invention relates to a method for measuring an analyte concentration in a specimen, including (1) preparing the specimen, (2) mixing a coloring reagent, an oxidoreductase, and a light-scattering adjustment reagent with the specimen to obtain an analysis sample having substantially the same scattered light as the specimen, and (3) measuring the analyte concentration by using the analysis sample.

摘要： A catheter includes an elongated shaft extending in a longitudinal direction and possessing an outer surface, the shaft possessing a distal end, a proximal end and a proximal portion which includes the proximal end, a transverse direction being perpendicular to the longitudinal direction, the elongated shaft being an elongated tubular body having a lumen formed therein, and a tubular hub fixed by insert molding to the outer surface of the shaft along the proximal portion of the shaft. The hub possesses a residual stress at one predetermined location of the hub that exceeds the residual stress of the hub at each of: (i) a first position distal to the one predetermined location, (ii) a second position proximal to the one predetermined location, and (iii) a third position being at the one predetermined location in the longitudinal direction and spaced apart from the one predetermined location in the transverse direction.

摘要： A stylet for axially stretching a catheter ensures flexibility in the distal side and a desired degree of stiffness in the proximal side to enable preferable insertion of a catheter assembly along a guidewire while preventing a kink or breakage. The stylet 50 includes a hollow outer layer tube 51 extending in an axial direction and a hollow inner layer tube 52 disposed in the inner periphery of the outer layer tube. The inner layer tube is formed from a material stiffer than that of the outer layer tube. In the inner layer tube, a distal portion has the inner periphery provided with a tapered diameter portion 52B having a diameter reduced toward the proximal side in the axial direction.

摘要： A blood component collection cassette of a blood component collection system, which is a biological component transfer system, includes a sheet-shaped cassette main body in which a blood line is formed. The blood line includes a second applied load measurement unit and line main body portions. A separation device includes a second load measurement unit that measures a load applied to a wall portion of the second applied load measurement unit in a cassette mounted state. The second applied load measurement unit is more easily deformed than the line main body portions, and is disposed at a location within the blood line on which only a positive pressure acts.
