Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a POCT analysis device. Background Art

[0002] Point-of-care testing (POCT) is a rapid testing method performed at the point of sampling using portable analytical instruments and supporting reagents to rapidly obtain test results. Using POCT equipment for immediate analysis at the point of sampling eliminates the complex laboratory handling required for specimen analysis and provides rapid results. Because POCT eliminates the need for a central laboratory and can be performed directly at the patient's location, it enables rapid diagnosis, treatment, nursing care, and disease progression monitoring, thereby improving healthcare quality. Consequently, POCT is gaining increasing popularity in ICUs, surgical departments, emergency departments, clinics, and even patients' homes. The primary purpose of POCT is to provide faster test results. Advances in diagnostic and ancillary technologies, as well as improved understanding and treatment of diseases, are the main reasons for the growing interest in POCT. These advances have brought some diseases close to eradication while enabling earlier diagnosis and better treatment for others. Simplicity and ease of use are another hallmark of POCT. Due to its ease of use, POCT has become an integral part of diagnostic systems.

[0003] Currently, there are blood glucose meters, uric acid analyzers, dry chemical analyzers, colloidal gold analyzers, microfluidic biochemical analyzers, immunofluorescence analyzers, chemiluminescence analyzers, etc. on the market. However, each analyzer can only detect one type of test item. This leads to the need for multiple types of analyzers to complete the test in some applications, which brings inconvenience to users and increases the user's equipment procurement costs and sample testing costs. In addition, the existing analyzer quality control system and calibration system are imperfect, and the differences between analyzers will affect the accuracy of the test results.

[0044] Specifically, the light collection device 3 includes a light source group 33, a spectroscopic chamber 32 and a collection optical fiber 14 arranged in sequence from top to bottom along the optical bracket 10. The light source group 33 is arranged above the optical bracket 10 to provide a variety of illumination wavelengths for the light collection device 3.

To the right of the beam splitter 17 where the collection fiber 14 forms a 45° angle with the beam splitter 17, a filter 13 and a photoelectric sensor 15 are sequentially positioned, each matching the wavelength of the light detected by the beam splitter. To the left of the beam splitter 17 where the collection fiber 14 forms a 135° angle with the beam splitter 17, a filter 13 and a photoelectric sensor 15 are sequentially positioned, each matching the wavelength of the light detected by the beam splitter.

[0054] By controlling the structure, materials, and assembly process of the stage component, the motor cooperates with the lead screw to drive the baffle 4 to move smoothly, and different types of test cards (strips) can be fixed normally. At the same time, the scanning device 2 is cooperated to confirm the fixed state of the test card (strip), and adjustments are made as needed to ensure that the test card (strip) does not shake during the test and is located in the center of the carrier 6; by controlling the assembly process of the spectrometer chamber 32, the placement angle of the spectrometer 17 is guaranteed to be consistent with the expectation to avoid affecting the light transmission; by controlling the material and assembly process of the light collection device 3, it is guaranteed that the various devices are tightly connected to prevent external ambient light from entering; the above steps can reduce the impact on the test results and ensure the reliable precision and accuracy of the detection system.
