  • Patent number: 9885731
    Abstract: A medical tested object auto-ejection structure comprises a detection instrument and a tested object (1). An insertion port is formed in the detection instrument. When the tested object (1) is inserted in the instrument through the insertion port, the bottom end of the tested object (1) presses a bulge (21) used for rebounding, and a raised step (11) arranged on the surface of one side of the tested object (1) is locked on a clamping buckle (31) arranged at a position corresponding to the step on the instrument simultaneously, and after a test is finished, the instrument releases the locking of the clamping buckle (31) for the tested object (1) by a transmission device, and the tested object (1) is ejected from the instrument in time under the action of the bulge (21) used for rebounding, thus solving the problem of forgetting to pull the tested object out or inability to pull it out in time, and improving the reliability of the product.

  • Patent number: 9625480
    Abstract: Disclosed are a linkage control device and a blood gas analyzer adopting the linkage control device. The linkage control device comprises a power unit and a rotating component (4) provided with bosses (41, 42). The power unit generates power to drive the rotating component (4) to rotate. The linkage control device further comprises valve components (5, 6, 7, 8), a signal control unit, sensing switches, and sensing pins (43, 44, 45, 46). The valve components (5, 6, 7, 8) are matched with the bosses (41, 42) of the rotating component (4) in a pushing manner. The signal control unit controls the start or stop of the power unit. The sensing switches are connected to the signal control unit via signals. The sensing pins (43, 44, 45, 46) are arranged in pair with the sensing switches and are arranged on the rotating component (4).

  • Publication number: 20160091408
    Abstract: The present invention relates to a detection system for improving accuracy of hematocrit measurement and an operation control method. The detection system for hematocrit measurement comprises a central processing unit, an excitation source unit, a blood sample unit, a precise measurement circuit unit and a signal collecting unit. The present invention has the beneficial effects that the HCT measurement precision is improved by generating a sine wave by the excitation source unit and performing control by the central processing unit; the detection system of the present invention is simple and reliable, and implements precise measurement; and the measurement precision in the present invention is far greater than that of a conventional measurement technology and can be within 0.2%. Furthermore, due to a self-detection function, the measurement is quite reliable without the risk of resulting incorrect measurement data from a circuit failure.

  • Patent number: 9056709
    Abstract: The side container includes one oblong under-frame; one oblong upper-frame; corner posts be installed on the four corners between under-frame and upper-frame; top surface panel, front end panel, back end panel and two side panels installed on the corner posts. The side panel has two side doors. At least one turnable locking bar should be installed on the upper area of the side door, and a latch hook should be installed on the bottom area of each locking bar. Cam keepers will be fixed on the under-frame. There is a cant hook installed between two permanent seats. When the under-frame is in a horizontal position, the cant hook is located above the latch hook. The side container can be fully open on an oblong side, while the side doors and the under-frame can still be securely locked, when the under-frame deforms downward during a full load condition.
