    摘要: A circuitry and a detection method using the circuitry. The circuitry includes circuits and electrochemical sensors connected to the circuits; the circuits include a reference voltage circuit, a potentiostatic circuit, and a micro-signal measuring circuit; on-off switches are provided on corresponding circuits. A test device and a detection method which use the circuitry can effectively reduce signal noise, reduce fluctuation of detection signals during a detection process, and improve the precision and accuracy of sample detection results.

    摘要: A flow sensor for pulmonary function testing is provided, and the flow sensor is capable of preventing cross-infection and has a hollow tubular structure. The flow sensor includes a main breather tube and a pressure tapping hole arranged on a tube wall of the main breather tube. An outer wall of the main breather tube is provided with a pressure tapping stub in air communication with the pressure tapping hole. The volume of an inner cavity of the pressure tapping stub satisfies following condition: during the pulmonary function testing, air exhaled or inhaled by a tester enters the pressure tapping stub through the pressure tapping hole and is kept within the pressure tapping stub without contacting a connection pipeline outside of the flow sensor. The flow sensor can isolate contaminants, i.e., bacteria or viruses and prevent the contaminants from entering other connection pipelines or cavities of a pulmonary function instrument.

    摘要: A method for evaluating inhalation administration and a system for evaluating inhalation administration, the system including a flow detector and an intelligent terminal. The method includes the following steps: 1) obtaining patient-related data of an inspiration flow-time curve; 2) according to an inspiration flow parameter of inhalation administration, obtaining a start time and an end time of each effective inspiration flow section on the inspiration flow-time curve; and 3) calculating an effective inspiration volume Veffective based on the inspiration flow-time curve and a series of time parameters ti1 and ti2 obtained. The method for evaluating inhalation administration and the system for evaluating inhalation administration provide a basis for medical workers to select an appropriate inhalation administration device for patients.
