A sampling method includes a sampling step and a cleaning step. The sampling step includes a first sample introduction step of introducing a first sample from a first cell culturing device to a more downstream side than a first connection portion in a sampling flow path, a first returning step of causing the first sample in the sampling flow path to flow into an introduction path from the first connection portion after the first sample introduction step, and a first flowing step of bringing the first sample into contact with a second sensor after the first returning step.

Sampling method

The object of the invention is to provide a blood separation device that can reduce the total time for drawing blood to obtain high-concentration platelet liquid, thereby reducing the binding time of the blood donor. The device includes a temporary storage bag (Y) (also serves as a buffy coat bag) which is a whole blood bag for storing whole blood drawn from a blood donor. The controlling unit of the device controls the device to draw whole blood from the blood donor in parallel with at least either a circulation flow step or an acceleration step, thereby storing the drawn whole blood in the temporary storage bag (Y).

A protector includes an outer tube and an inner tube. The outer tube includes an outer tube main body including an outer tube lumen for housing a puncture device, a holding part for holding a hub, and an extended part extended from the holding part. The inner tube includes an inner tube main body and a lumen inclined part. The inner tube main body is held in a proximal end side of the outer tube lumen and is movable in a proximal end direction of the outer tube lumen. The inner tube main body includes an inner tube lumen into which a tube is inserted. By moving the inner tube in a distal end direction, the inner surface of the lumen inclined part is abutted against the extended part, and the extended part is biased by the lumen inclined part in a direction in which a diameter of the tube is reduced.

An optical fiber unit for medical examination and treatment according to the invention has an object of not requiring a light condensing lens group by tapering the tip end side of the optical fiber light guide. Optical fiber light guide,has flexibility and guides light including infrared rays emitted from a light source to probe,which is located at the tip end thereof, through a flexible guide tube,The tapered conduit part,the diameter of which is made smaller toward the tip end thereof condenses the light and allows the same to be emitted from the tip end plane of the probe,The rectilinear polarization plate,rectilinearly polarizes light including infrared rays emitted from the tip end plane of the tapered conduit part,and irradiates the same onto an affected part.

Optical fiber unit for medical examination and treatment and arm device for the optical fiber

An arm device for retaining and positioning an optical fiber unit for medical examination and treatment, so as to easily operate the same. The arm device is provided with flexible arm parts and a lockable, rotatable joint assembly for easy manipulation and positioning of the optical fiber unit.
