[0018] Example

[0019] Please see Figure 1-3 This utility model provides a technical solution: an optical detection device for a medical biochemical analyzer;

[0020] This invention aims to provide an optical detection device for medical biochemical analyzers that facilitates efficient operation, as existing optical detection methods are inefficient.

[0021] Based on the above issues, the components in this case include a base 1, a frame 2 is provided on one side of the top of the base 1, a first electric push rod 3 is provided on the upper side of the frame 2, the output end of the first electric push rod 3 passes through the upper side of the frame 2 and is connected to a spiral frame 4, a first light source 5 is provided on the upper side inside the spiral frame 4, and a driving component 6 is provided at the bottom of the base 1, the driving end of the driving component 6 passes through the base 1 and is connected to a rotating disk 7.

[0022] A ring of limiting components is provided on the outer side of the rotating disk 7. A notch is provided on the lower side of the limiting components. A second electric push rod 8 is installed on the top of the base 1. The output end of the second electric push rod 8 is connected to a lifting frame 9. A second light source 10 is connected to one side of the lifting frame 9. A photodetector 11 is provided on the lower side of the frame 2.

[0023] The limiting component includes a socket 12 opened on the rotating disk 7. The socket 12 is located on the upper side of the notch. Both sides of the inner wall of the socket 12 are connected to a return spring 13. One side of the return spring 13 is connected to an elastic clamping block 14.

[0024] It should be noted that when performing optical detection on human body fluids or blood samples, multiple test tubes containing samples are first inserted into the socket 12, and the lower side of the test tubes is made to pass through the notch. At this time, the reset spring 13 and the elastic clamping block 14 cooperate to fix the test tubes inside the socket 12. Then the drive unit 6 runs, which can move the test tubes inserted on the transmission plate to the frame 2.

[0025] Subsequently, the first electric push rod 3 operates, which can drive the first light source 5 to descend through the ring frame 4 and emit vertical light towards the sample inside the test tube. In conjunction with the photodetector 11, the sample inside the test tube can be photodetected. Then, the first electric push rod 3 resets, and the second electric push rod 8 operates, which drives the second light source 10 to extend into the notch and illuminate the sample inside the test tube horizontally. In conjunction with the photodetector 11, the photodetector performs the photodetector operation again. The results of the two tests are combined to increase the accuracy of the test.

[0026] Among them, the first light source 5 and the second light source 10 can emit transmitted light or scattered light, and the photodetector 11 is a transmitted light detector 11 or a scattered light detector 11. The above components work together to complete the light detection operation of the sample inside the test tube. The main function of the detachable monochromator 15 is to separate a single wavelength of light from the multi-color light source, increase the light detection effect of the sample inside the test tube, and ensure that only light of a specific wavelength can pass through the monochromator and illuminate the sample.

[0027] The frame 2 is provided with reinforcing ribs 16 on the lower side to increase the stability of the frame 2, and the base 1 is provided with support feet 17 at the four corners of the bottom to support the device.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
