Description

Technical Field

[0001] The present invention relates to the technical field of blood testing, and in particular to a hemoglobin testing and analysis instrument. Background Art

[0002] The clinical significance of hemoglobin determination is the same as that of red blood cell count. However, in various anemias, the two may be inconsistent due to the different hemoglobin contents in red blood cells. For example, in iron deficiency anemia, the red blood cell count rarely decreases and sometimes even increases. Glycated hemoglobin is the product of the combination of hemoglobin and blood sugar in red blood cells in human blood. It is an indicator that reflects the average blood sugar level in the past 2 to 3 months, and is not affected by temporary accidental factors. It has nothing to do with whether the patient is fasting when blood is collected. Therefore, it can stably and reliably reflect the blood sugar control level for a long time. The common method for determining hemoglobin and glycated hemoglobin is to make a judgment by comparing the difference in absorbance.

[0003] Announcement No. CN214750364U discloses a glycated hemoglobin detection device. Although the above-mentioned prior art can receive reflected light through a light processing device to measure the absorbance of the test sample, the glycated hemoglobin content can be measured according to the absorbance to determine whether it is diabetes. However, before detecting the absorbance of the glycated hemoglobin sample, it is necessary to add an anticoagulant and a liquid reagent to the sample. After adding these two substances to the sample, it is necessary to shake it gently to allow the sample and the added substances to be fully mixed. However, during the mixing process, it is necessary to be gentle and try to avoid the generation of bubbles. Each shaking takes about two minutes, and each glycated hemoglobin test is performed on multiple samples at the same time, and multiple samples need to be shaken. On the one hand, it puts a heavy workload on the staff, and on the other hand, it is time-consuming and inefficient.

[0004] Announcement No. CN221174397U discloses a glycated hemoglobin detection device, including a detection platform, a light source box is provided on one side of the detection platform, and a light source component for detecting glycated hemoglobin samples using an immunoagglutination method is provided inside the light source box; by arranging a mixing component, a driving component and a moving component, the driving component is used to drive the mixing component to rotate the mixing component, and after the mixing component rotates, the sample will revolve around the mixing component, and the sample itself will rotate in the opposite direction of the revolution, thereby increasing the mixing degree of the sample, and such slow shaking will prevent bubbles from being generated inside the sample.

[0005] However, the above technology still has the following problems: by setting up four groups of fixed sleeves for carrying sample test tubes and being synchronously driven by four groups of synchronous belts, since the fixed sleeves are distributed in a ring shape and the light source in the detection box is irradiated from the top, and the absorbance detection instrument is arranged laterally in the light source box, the distance between the sample test tubes in each fixed sleeve and the analyzer in the detection box is inconsistent, which makes the error range of the detection content of each test tube larger, affecting the determination.

The butterfly bolt 725 is The end abuts against the slide 723, and by loosening the butterfly bolt 725, the slide 723 slides upward along the guide rod 722 under the elastic force of the first spring 724, thereby increasing the distance between the slide and the toothed disk 71, and the first hinge seat 731 moves outward with the half jacket 735 under the pulling of the first connecting rod 732 and the second connecting rod 733, thereby increasing the clamping distance, and after the test tube is placed, the butterfly bolt 725 is tightened to move the second arc plate 742 at the bottom of the slide 723 downward to press the test tube.

By tightening the butterfly bolt 725, the second arc plate 742 at the bottom of the slide seat 723 moves downward, and the tube cap of the test tube is pressed into the upper clamping groove 744 on the bottom surface of the second arc plate 742. At the same time, the half jackets 735 on both sides can be clamped at the middle position of the test tube body to complete the fixation of the test tube.

[0039] See also Figure 8 , Fig.10 and Fig.11The shaking assembly 74 includes a first arc plate 741 and a second arc plate 742. The top surface of the first arc plate 741 is provided with a lower groove 743 adapted to the bottom of the test tube, and the bottom surface of the second arc plate 742 is provided with an upper groove 744 adapted to the test tube cap.

A key groove 746 is provided on the arc slider 745 on the outer arc surface of the second arc plate 742.

[0040] See also Figure 8 , Fig.12 and Fig.13 The telescopic assembly 75 includes a slide bar 751, a telescopic cavity 727 is provided on the slide seat 723, the slide bar 751 is slidably arranged in the telescopic cavity 727, and a key tooth 752 is provided on the middle lower surface of the slide bar 751 that meshes with the key groove 746. Both ends of the slide bar 751 are fixed with a pressure ring 753, and a magnetic column 754 is fixed on the outer end surface of the pressure ring 753. One end of the magnetic column 754 extends outside the telescopic cavity 727, and the part where the magnetic column 754 is located in the telescopic cavity 727 is sleeved with a second spring 755. The two ends of the second spring 755 are respectively fixed to the pressure ring 753 and the inner wall of the telescopic cavity 727. It should be noted that the outer end poles of the two magnetic columns 754 of one telescopic assembly 75 in the same group are opposite, and the outer end poles of the two magnetic columns 754 of the other telescopic assembly 75 in the same group are the same. Since the transmission ratio of the toothed disc 71 of the two carriers 7 in the same group is one to one, during the rotation of the two carriers 7 in the same group, such as Fig.12 As shown, when the two telescopic components 75 of the group are close to each other, the oppositely charged magnetic poles 754 can make the two telescopic components 75 approach each other, as shown in FIG. Fig.13 As shown, the two carriers 7 in the same group rotate 180 degrees respectively. At this time, the repulsive effect of the two magnetic columns 754 at the proximal ends of the two telescopic components 75 in the group can make the two telescopic components 75 move away from each other.

[0041] The working principle and use process of the present invention are as follows: by loosening the butterfly bolt 725, under the elastic force of the first spring 724, the slide seat 723 slides upward along the guide rod 722, thereby increasing the distance between the slide seat 723 and the toothed disc 71, and by pulling the first connecting rod 732 and the second connecting rod 733, the first hinge seat 731 moves outward with the semi-jacket 735, thereby increasing the clamping distance, thereby facilitating the bottom of the test tube of the blood sample to be placed in the lower clamping groove 743, and then tightening the butterfly bolt 725 to move the second arc plate 742 at the bottom of the slide seat 723 downward, and press the tube cap of the test tube into the upper clamping groove 744 on the bottom surface of the second arc plate 742, while at the same time, the semi-jacket 735 on both sides can be clamped in the middle position of the test tube body to complete the fixation of the test tube;

[0042] The driving unit 5 is turned on to drive the rotating arm 6 to rotate, thereby driving the two groups of carriers 7 on the rotating arm 6 and the test tubes on the two groups of carriers 7 to rotate around the center of the rotating arm 6. In this process, since the position of the first pulley 81 remains unchanged, the second pulley 82 rotates around the first pulley 81, and the two outer carriers 7 can be driven to rotate by themselves under the synchronous drive of the synchronous belt 83. Under the transmission engagement of the two toothed discs 71 of the two carriers 7 in the same group, the two groups of carriers 7 can also rotate by themselves while rotating around the center of the rotating arm 6, thereby mixing the solution in the test tube with the solvent;

[0043] Since the outer magnetic poles of the two magnetic columns 754 of one telescopic assembly 75 are opposite, and the outer magnetic poles of the two magnetic columns 754 of the other telescopic assembly 75 are the same, the transmission ratio of the toothed discs 71 of the two carriers 7 in the same group is one to one. Fig.12 As shown, when the two telescopic components 75 of the group are close to each other, the oppositely charged magnetic poles 754 can make the two telescopic components 75 approach each other, as shown in FIG. Fig.13 As shown, the two carriers 7 in the same group rotate 180 degrees respectively. At this time, the repulsion of the two magnetic columns 754 at the proximal ends of the two telescopic components 75 in the group can make the two telescopic components 75 move away from each other, as shown in FIG. Figure 8 As shown, when the telescopic assembly 75 overcomes the elastic force of the second spring 755 and moves to the right, the key teeth 752 at the bottom of the slide bar 751 are engaged with the key slot 746, which can drive the test tube to have a tendency to move to the right. Since the middle of the test tube body is clamped by the half jackets 735 on both sides, the test tube can swing clockwise around the rotating shaft 736, and vice versa, the test tube swings counterclockwise around the rotating shaft 736, that is, the sample test tube swings back and forth up and down under the clamping of the clamping assembly 73, further increasing the mixing effect.

[0044] After the mixing is completed, the carrier 7 of the device is kept at Figure 1The two groups of carriers 7 are arranged in a straight line on the rotating arm 6, and the distances between the two groups of carriers 7 and the light source and the analyzer in the detection box 2 are the same, so the hemoglobin content of different test tubes can be accurately determined.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
