Description

Cell detector

Technical Field

The utility model relates to the technical field of cell detection, in particular to a cell detector.

Background

The cell detector is a key device widely applied in the fields of biomedical research, clinical diagnosis, biotechnology and the like, and has the main function of realizing high-precision and high-efficiency detection and analysis of cell samples. With the continuous progress of scientific research and medical fields, the requirements on the detection efficiency, accuracy and automation degree of the cell detector are higher and higher.

In conventional cell detection techniques, most cell detectors are based on a single detector design. The main advantage of this design is simplicity and reliability, facilitating user operation and maintenance. However, this also brings a significant limitation in that when multiple cell samples are to be tested, these samples can only be loaded sequentially for testing, and parallel processing cannot be achieved. This clearly increases the detection time, and presents a significant efficiency bottleneck for scenarios requiring rapid acquisition of results, such as emergency diagnostics or large-scale sample analysis.

For modern scientific laboratories, medical diagnostic centers, and biotechnology companies, the sample size is often large-scale and often requires detection results in a short period of time. For example, when a disease is prevalent or an epidemic outbreak, a large number of samples need to be detected and analyzed in a minimum amount of time, and conventional single detector designs are not able to meet this high efficiency requirement.

In addition, along with the development of personalized medicine and accurate medicine, the high-throughput and high-efficiency requirements on the cell detector are more urgent. The single detector design allows only one sample to be processed at a time, which significantly reduces the overall operating efficiency of the detector, especially when multiple parameters need to be analyzed.

Therefore, in view of the above-mentioned technical problems, it is necessary to provide a new cell detector.
