Abstract: 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.

Abstract: 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 (Y2) (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 (Y2).

Abstract: 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.

Abstract: A protector (1) is used by being attached to a puncture device (50). The protector (1) includes an outer tube (2) and an inner tube (9). The outer tube (2) includes an outer tube main body (3) including an outer tube lumen (4) for housing the puncture device (50), a holding part (5) for holding a hub (52), and an extended part (8) extended from the holding part (5) in a proximal end direction. The inner tube (9) includes an inner tube main body (10) and a lumen inclined part (12). The inner tube main body (10) is held in a proximal end side of the outer tube lumen (4) and movable in a proximal end direction of the outer tube lumen (4). The inner tube main body (10) includes an inner tube lumen (11) into which a tube (53) is inserted. In the lumen inclined part (12), an inner diameter of the inner tube lumen (11) gradually increases toward a distal end side of the inner tube main body (10).

Abstract: 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 1 has flexibility and guides light including infrared rays emitted from a light source to probe 4 which is located at the tip end thereof, through a flexible guide tube 3. The tapered conduit part 5, 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 4. The rectilinear polarization plate 8 rectilinearly polarizes light including infrared rays emitted from the tip end plane of the tapered conduit part 5 and irradiates the same onto an affected part.

Abstract: 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.

Abstract: A print control mechanism for a dot matrix printer for effecting normal printing speed relative to response time of the print elements. The mechanism includes a memory for storing the status of a previous printing operation by one print element prior to a subsequent printing operation by the same print element. The mechanism includes print inhibiting means coupled to the memory and adapted to compare a print command signal with a memory signal and to output a signal forbidding the subsequent printing operation by the same print element when it receives a print command signal following the previous printing operation. The effect of this mechanism is to inhibit continuous printing of dots in very dot position in the lateral direction for those characters which can be printed with dots in every other dot position to enable normal printing speed.

Abstract: A passbook printer has a print head movable along a printing station and in opposed relation to a platen for printing data on the passbook. The printer has an optical reading head assembly which is movable independent of the print head and in a direction of the path of the passbook past the printing station. The optical reading head assembly is positioned at the printing station for reading page and line information from the passbook and then is moved to a position adjacent the printing station for permitting the print head to freely move along the printing station.

Abstract: A control mechanism for a record media cutting blade has a carriage for moving the cutting blade from a home position to a record media cutting position. The carriage has a photosensor secured thereto and is operably associated with a first reflecting member at the home position of the carriage and with a second reflecting member at the record media cutting position of the carriage. The second reflecting member is operably associated with the photosensor for partial cut or for full cut of the record media by the cutting blade. The movement of the carriage is controlled by the output of the photosensor to a comparator, to a converter and to a central processing unit.
