Abstract: The exhalation measurement device of certain implementations comprise a chamber, a measurement component, a piezoelectric pump, a first learning controller, and a second learning controller. The chamber may temporarily hold exhalation. The measurement component may measure a specific component in the exhalation. The piezoelectric pump may supply the measurement component with the exhalation held in the chamber. The first learning controller may perform operational setting on the piezoelectric pump before the piezoelectric pump supplies the exhalation in the chamber to the measurement component. The second learning controller may perform operational setting on the piezoelectric pump after the piezoelectric pump has started supplying the exhalation in the chamber to the measurement component, but before the measurement component performs its measurement.

Abstract: A flow rate detector of an exhalation measurement device includes: a pipe body having a flow inlet at a first end into which exhalation flows, and a flow outlet at a second end out of which exhalation flows; and a differential pressure sensor connected to the pipe body. The pipe body includes: a partition gasket which partitions the inside of the pipe body into a flow-in space of exhalation and a flow-out space of exhalation; a connection aperture being provided at the flow-in space and connecting the differential pressure sensor to the flow-in space; a connection aperture being provided at the flow-out space and connecting the differential pressure sensor to the flow-out space; and an air duct of an elongated shape, extending through the partition gasket and allowing the flow-in space and the flow-out space to communicate with each other.

Abstract: Certain implementations relate to an exhalation measurement device that is used in checking pulmonary function, diagnosing asthma, and may perform zero point correction accurately even when there is disturbance. The exhalation measurement device may comprise a flow regulator. The flow regulator comprises a first offset adjuster that puts an exhalation inflow component and an exhalation outflow component in a separated state and performs first offset adjustment of an inflow pressure sensor and an outflow pressure sensor, a voltage difference detector that puts the exhalation inflow component and the exhalation outflow component in a linked state and detects an output voltage difference after the first offset adjustment of the inflow pressure sensor and the outflow pressure sensor, and a second offset adjuster that uses the output voltage difference to perform second offset adjustment of the inflow pressure sensor.

Abstract: Disclosed are a method for early, sensitively and reliably detecting and distinguishing intrahepatic cholangiocarcinoma in a malignant tumor occurring primarily in the liver in a simple way, and a kit thereof. In the method, a glycan biomarker consisting of a lectin WFA (Wisteria floribunda Agglutinin)-binding glycoprotein derived from intrahepatic cholangiocarcinoma is used as a cancer marker to detect intrahepatic cholangiocarcinoma by detecting the cancer marker in a test specimen. The method for detecting intrahepatic cholangiocarcinoma can clearly differentiate intrahepatic cholangiocarcinoma from hepatocellular carcinoma and enables early detection and determination with a performance clinically acceptable in terms of applicability, sensitivity and precision.
