  • Patent number: 10463289
    Abstract: Upon blood collection with a disclosed blood collecting apparatus, a part of a flow path adjacent to a suction drain mechanism is filled with a liquid different from the blood. A gas is inserted in the flow path between the liquid with which the part of the flow path adjacent to the suction drain mechanism is filled and a target blood to be collected. The suction drain mechanism pushes and pulls the gas by pushing and pulling the liquid during a standby time between collection and next collection, thereby controlling movement of the target blood. The suction drain mechanism pushes and pulls the liquid and the gas during the standby time, whereby the target blood is continuously moved. This allows prevention of coagulation of the target blood in the flow path.

  • Patent number: 10355374
    Abstract: A terminal fitting (1) includes a rectangular tube (11) with a bottom wall (12), two side walls (13A, 13B) rising from the bottom wall (12) and a ceiling wall (15) facing the bottom wall (12). The rectangular tube (11) includes a terminal insertion opening (17) on one end, and a tab (T) is insertable therein. A resilient contact piece (21) is arranged along the bottom wall (12) inside the rectangular tube (11). Two protection walls (31A, 31B) extend respectively from the side walls (13A, 13B) to close the terminal insertion opening (17), leaving a clearance for entrance of the tab (T) between the ceiling wall (15) and the protection walls. The protection walls (31A, 31B) have facing edges (35A, 35B) facing the mating protection walls (31B, 31A), and the facing edges (35A, 35B) extend obliquely with respect to a line (L) perpendicular to the bottom wall (12).

  • Patent number: 10271782
    Abstract: A suction drain device of a disclosed liquid collecting apparatus actively pushes and pulls blood. This achieves liquid collection at high speed even under decreased pressure depending on a physiological state of an animal. Moreover, the liquid collecting apparatus includes a first flow path and a second flow path having a given length. Accordingly, the flow path with a given length set in advance and thus a known volume allows collection of a given amount volume of blood without measuring a length and an amount of blood using a volume measuring device. Accordingly, no need of the measuring device allows reduction in size of the liquid collecting apparatus. Consequently, the liquid collecting apparatus can be installed adjacent to the animal to achieve reduction in dead volume. Moreover, blood is flown to a fourth flow path branched with a connecting terminal, and is also flown to the second flow path branched with a connecting terminal.

  • Patent number: 10126445
    Abstract: Sensitivity correction for multiple ? radiation detectors is performed by use of sensitivity coefficients obtained through a first sensitivity coefficient calculation step for obtaining sensitivity coefficients, classified according to sensitivity factors, on the basis of coincidence counting data collected as a result of detection of ? radiation emitted from a rotated rod-shaped calibration radiation source, and through a third sensitivity coefficient calculation step for obtaining sensitivity coefficients derived from a geometrical arrangement on the basis of coincidence counting data collected in a state where arrangement of the ? radiation detectors is changed. A re-constructed image is obtained on the basis of data acquired after the sensitivity correction is finished.
