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.

Abstract: In some implementations, an apparatus for processing one or more signals may include an amplifier and circuitry. The circuitry may be coupled to the amplifier. The circuitry may set a first threshold indicating a first signal strength which is a positive value, and a second threshold indicating a second signal strength greater than the first threshold. The circuitry may receive a signal having a signal strength varying over time. The circuitry may enter a first state and start a timer set to a first time period. In response to the first time period ending, the circuitry may switch to a second state. In the second state, the circuitry may determine that the signal strength of the signal is greater than the second threshold, decrease a gain of the amplifier, and switch to the first state.

Abstract: Provided are cell image analysis devices and sample analysis methods. A sample smear of a test sample is imaged by an imaging device in an assigned analysis mode to obtain first cell images of the test sample, which are identified and analyzed by a control device. If it is identified that there is preset abnormality in the sample smear, an analysis mode different from the assigned analysis mode and corresponding to the present abnormality is determined as an additional analysis mode, and the imaging device is controlled to image the sample smear in the additional analysis mode. The additional analysis mode matches with the preset abnormality, so that the imaging device is allowed to obtain cell images in the additional analysis mode, to identify and analyze the cell images matching the preset abnormality, thereby increasing processing efficiency and accuracy of processing result.

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.

Thus, the accuracy of platelet detection can be improved when the number of platelets in the blood sample is low.
