  • Publication number: 20220334100
    Abstract: A sample analysis system, method and a cell image analysis device. The sample analysis system includes a blood cell analyzer, a smear preparation apparatus, a cell image analysis apparatus, and a controller. The controller obtains a test result of at least one sample from the blood cell analyzer. When one sample needs to be analyzed by the cell image analysis device, the controller can further control an imaging condition used by the cell image analysis device according to a value of at least one type of cells in the test result of the sample, such that the cell image analysis device can automatically selects an imaging condition matching the test result for imaging according to different test results of the sample. Therefore, a matching imaging condition is used to specifically capture and analyze cell images of a smear of the sample, thereby improving processing efficiency and accuracy.

  • Patent number: 11454575
    Abstract: A method and a machine for drying blood smears and an automatic smearing device are provided. In the method, a dry gas is used as a drying medium to dry a blood film on a blood smear in drying the blood smear, thus reducing drying time and the number of blood smears which are dried together. The dry gas is obtained by: first, removing a liquid from a pressurized gas, second, filtering a vapor, and finally, decompressing the dried pressurized gas to be a non-pressurized gas having lower humidity. In addition, the dry gas is further heated for further reducing the humidity of the dry gas. In order to prevent cell distortion from occurring, the heated dry gas is caused to gently flow over the blood smear in a direction which the blood film is spread.

  • Publication number: 20200129100
    Abstract: A blood detection method and a blood detection device are disclosed. When a count number of platelet in a blood sample is less than a predetermined value, a detection solution of the blood sample is prepared. A cell statistical amount of the detection solution of the blood sample is increased to obtain the platelet detection result. The cell statistics amount of the detection solution of the blood sample may be increased in an impedance detection area to perform PLT-I detection, or in an RET detection area; or performing both of RET detection and PLT-O detection simultaneously. Thus, the accuracy of platelet detection can be improved when the number of platelets in the blood sample is low.
