Description

Technical Field

[0001] The present invention relates to the field of medical device technology, and in particular to a cardiovascular disease detection device. Background Art

[0002] In recent years, the incidence of cardiovascular diseases has become younger and younger, and the treatment options for cardiovascular diseases are very limited. There may be a variety of sequelae after treatment, which seriously affect the quality of life of patients.

[0003] For cardiovascular diseases, miRNA molecules can be released in the relevant tissue cells of patients. Therefore, when diagnosing cardiovascular diseases, miRNA molecules can be used as markers for diagnosis, thereby achieving the effect of early and accurate diagnosis of the disease.

[0004] For example, the patent application number: CN202210782808.4 discloses a detection system for mi RNA markers for the diagnosis of cardiovascular diseases. The application uses a light source to emit a laser of a specific wavelength into the reaction chamber. The laser can penetrate the transparent cover and shine into the reaction chamber to excite the fluorescent groups in the amplification reagent. The generated fluorescence can be obtained by the photoelectric detection module through the transparent cover, thereby obtaining the corresponding fluorescence amplification data and achieving the effect of marker detection.

[0005] For example, the patent with application number: CN202011155376.1 discloses an immunoquantitative detection device, detection method and use of cardiovascular disease markers. The immunoquantitative detection device and detection method of cardiovascular disease markers of this invention are of great significance and good application prospects for improving the existing immunodetection technology of cardiovascular disease markers.
