[0004] The Chinese invention patent application with the publication number CN103499527A discloses "an improved structure for improving the detection accuracy of a clinical in vitro detection analyzer". Technical issues with insufficient precision of results
However, when the sample tray slides down the guide rail, due to insufficient flatness of the guide rail surface, or unstable friction coefficient between the sample tray and the guide rail, or poor lubrication of the rollers on the guide rail, or other uncertainties Due to factors, the sample tray is often stuck on the guide rail, which leads to the interruption of the work of the clinical in vitro detection analyzer. The general solution is to improve the processing and assembly accuracy of the guide rail and the sample tray, or even change the production material. Increased the manufacturing cost of clinical in vitro detection analyzers, which is unacceptable by the market

Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] see figure 1 , Figure 1 It shows a sample loading system of a clinical in vitro detection analyzer. There are five places for placing reaction plates 1 in the sample loading tray 2. The reaction plate 1 is placed in the sample loading tray 2 and first moves along the X direction with the sample loading tray. Moving along the Y direction, the reaction plates 1 pass under the detection head 4 one by one for detection.
[0027] figure 2 The structure of the guide rail is clearly shown.
[0028] image 3 The structure of the sample loading tray is clearly shown, and the reaction plate is placed in the sample loading tray.
[0029] see Figure 4-6 , Figure 4-6 is the focus of this embodiment. An anti-jamming device for automatic loading of the reaction plate of a clinical in vitro detection analyzer, the clinical in vitro detection...

The invention relates to an anti-blocking device for automatic loading of a reaction plate of a clinical in-vitro detection analysis meter. The clinical in vitro detection analysis meter comprises a guide rail (3) with a certain inclination angle; a loading tray (2) slides along the guide rail. The anti-blocking device is characterized in that the direction in which the loading tray (2) slides along the guide rail (3) is set as a direction X, and a direction vertical to the direction X is set as a direction Y; a cover plate (5) is also fixedly arranged above the loading tray (2); an electromagnet (6) is fixedly arranged on the cover plate (5); an ejector rod of the electromagnet (6) corresponds to a stop block (7); the stop block (7) is fixedly connected with the guide rail (3); on the cover plate (5), a midway sensor (5a) and an in-place sensor (5b) used for detecting the loading tray (2) are orderly arranged along the direction X; when the loading tray (2) is detected by the midway sensor (5a) and not detected by the in-place sensor (5b) after a time delay, the stop block (7) is knocked by the electromagnet (6).
Description
technical field [0001] The invention relates to a clinical in vitro detection analyzer, in particular to an anti-jamming device and method for automatic loading of a reaction plate of a clinical in vitro detection analyzer, belonging to the technical field of clinical in vitro detection and analyzers. Background technique [0002] POCT, point-of-care testing, refers to clinical testing performed next to the patient. It is a new type of test that is analyzed immediately at the sampling site, eliminating the need for complicated processing procedures during laboratory testing, and quickly obtaining test results. method. The main criteria of POCT are that no fixed testing site is required, reagents and instruments are portable, and can be operated in a timely manner. In recent years, due to the development of today's high-tech and medical science, as well as efficient and fast-paced working methods, POCT, which has the advantages of miniaturization of experimental instruments,...
