Description

Technical Field

[0001] This utility model relates to the field of blood typing technology, and in particular to a device for precise preparation of blood typing reverse typing cell concentration. Background Technology

[0002] Blood typing is a method of determining a person's blood type by detecting the specific antigens on the surface of red blood cells. The principle is that when the antigens on the surface of red blood cells bind with the corresponding antibodies, agglutination occurs. Commonly used identification methods include positive typing, reverse typing, and technical methods. Reverse typing is used to verify the accuracy of the positive typing structure.

[0003] Blood typing includes forward and reverse typing tests. Reverse typing involves the reaction of the patient's serum with reagent AB cells. The cell concentration required for the test card is 0.8%, which requires medical staff to manually prepare the cell concentration and then judge the color of the cells by visual inspection based on experience.

[0004] The existing technology has the following defects and directions for improvement: (1) When performing reverse typing, in order to avoid the situation where the antibody is in the excessive antigen or the antigen and antibody cannot cross-link into agglutination due to insufficient antigen, it is necessary to prepare a red blood cell suspension with a standard concentration range. However, in actual operation, the tester usually needs to judge the red blood cell concentration by observation, which makes the accuracy of the red blood cell concentration judgment poor. (2) Moreover, when observing, it is inconvenient to arrange multiple test tubes neatly for simultaneous observation, which makes the overall detection efficiency low.

[0005] Based on this, a device for precise preparation of blood type reverse typing cell concentration should be proposed to solve the above problems. Utility Model Content

[0027] Please refer to Figure 1 This embodiment proposes a device for precise preparation of blood type reverse typing cell concentrations, including an outer frame 1. A reagent kit 2 is slidably connected to the inner wall of the outer frame 1. A horizontal plate 19 is mounted on the upper surface of the outer frame 1, and the horizontal plate 19 is parallel to the outer frame 1. A camera 20 is fixedly connected to the side of the horizontal plate 19 closest to the reagent kit 2.

[0028] The following is a detailed explanation of its overall setup and function.

[0029] This implementation plan: Please refer to Figure 1 and Figure 4An L-shaped plate 3 is detachably installed on the side of the outer frame 1 near the vertical rod 18. A second sliding groove is provided on the side of the L-shaped plate 3 near the vertical rod 18. A T-shaped block 12 is slidably connected to the surface of the second sliding groove on the L-shaped plate 3. The T-shaped block 12 is installed on the side of the vertical rod 18 away from the horizontal plate 19. The L-shaped plate 3 facilitates the connection and separation of the vertical rod 18 from the outer frame 1, while the T-shaped block 12 ensures that the vertical rod 18 can move.

[0030] Please refer to Figure 1 and Figure 3 A clamping plate 4 is slidably connected to the side of the "L"-shaped plate 3 closest to the outer frame 1. A first sliding groove is formed on the side of the "L"-shaped plate 3 closest to the clamping plate 4. A slider 6 is slidably connected to the surface of the first sliding groove on the "L"-shaped plate 3, and the slider 6 is fixedly connected to the clamping plate 4. The slider 6 ensures a stable connection between the clamping plate 4 and the "L"-shaped plate 3, while allowing the clamping plate 4 to move relative to the "L"-shaped plate 3. Thus, the "L"-shaped plate 3 is installed by clamping the outer frame 1 with the clamping plate 4 and the "L"-shaped plate 3.

[0031] Please refer to Figure 3 A screw 7 is rotatably connected to the side of the slider 6 away from the clamping plate 4. A ring 8 is fitted onto the surface of the screw 7, and the internal thread of the ring 8 matches the external thread of the screw 7. A washer 9, made of rubber, is glued to the side of the ring 8 closest to the "L"-shaped plate 3. The screw 7, rotatably connected to the slider 6, can rotate, thereby adjusting the position of the ring 8. The ring 8 and the washer 9 press against the surface of the "L"-shaped plate 3, thus restricting the movement of the clamping plate 4.

[0032] Please refer to Figure 2 and Figure 3 Both the clamping plate 4 and the "L"-shaped plate 3 have rubber plates 5 glued to the side near the outer frame 1. The slider 6 is fixedly connected to the side near the ring 8 with a limiting rod 10, which is slidably connected to the inner wall of the ring 8. When using the clamping plate 4 and the "L"-shaped plate 3 to clamp the outer frame 1, the rubber plates 5 can improve the clamping effect and stability. The limiting rod 10 can restrict the rotation of the ring 8 during its movement.

[0033] Please refer to Figure 4 A fixing plate 22 is fixedly connected to the side of the "T"-shaped block 12 closest to the vertical rod 18. The fixing plate 22 is fixedly connected to the vertical rod 18. A toothed plate 11 is fixedly connected to the side of the fixing plate 22 away from the outer frame 1. The toothed plate 11 fits tightly against the "L"-shaped plate 3. The fixing plate 22 connects the "T"-shaped block 12 to the vertical rod 18, and the toothed plate 11 allows for easy control of the movement of the fixing plate 22 and the "T"-shaped block 12.

[0034] Please refer to Figure 4A control panel 13 is fixedly connected to the side of the "L"-shaped plate 3 closest to the toothed plate 11. A connecting plate 14 is fixedly connected to the side of the "L"-shaped plate 3 closest to the control panel 13. A motor 15 is fixedly connected to the upper surface of the connecting plate 14. A rotating rod 16 is fixedly connected to the output end of the motor 15. A gear 17 is fixedly connected to the other end of the rotating rod 16. The gear 17 is rotatably connected to the "L"-shaped plate 3 and meshes with the toothed plate 11. The control panel 13 can control the start and stop of the motor 15, thereby controlling the rotation of the rotating rod 16 and the gear 17 to adjust the position of the toothed plate 11.

[0035] Working principle: When it is necessary to determine the concentration of reverse-typed cells, firstly, move the "L"-shaped plate 3 closer to the outer frame 1, then move the clamping plate 4 so that the slider 6 slides on the first groove surface on the "L"-shaped plate 3, thereby driving the clamping plate 4 closer to the outer frame 1. Rotate the screw 7, and at this time, under the restriction of the limiting rod 10, the ring 8 drives the washer 9 closer to the "L"-shaped plate 3, restricting the movement of the clamping plate 4. At this time, under the squeezing action of the clamping plate 4, the "L"-shaped plate 3, and the rubber plate 5, the connection between the "L"-shaped plate 3 and the outer frame 1 is completed. Then, the connecting plate 1 is activated through the control panel 13. The motor 15 on the 4 drives the rotating rod 16 and gear 17 to rotate, thereby controlling the toothed plate 11 and the fixed plate 22 to drive the "T" block 12 to slide on the surface of the second groove on the "L" plate 3, so that the vertical rod 18 and the horizontal plate 19 move. During this process, the camera 20 feeds back its position relative to the configuration test tube in the reagent kit 2 to the control panel 13, so that the control panel 13 can control the horizontal plate 19 to move to the position where the camera 20 matches the configuration test tube. Then, the red blood cell suspension in the configuration test tube is configured, and the concentration information is displayed on the display screen 21. The camera 20 can collect information on the state of the red blood cell suspension in the test tube, and the collected information is processed by the control panel 13. The concentration information of the red blood cell suspension in the test tube is then arranged and displayed, improving the accuracy of the red blood cell concentration determination. The "L"-shaped plate 3 and the clamp 4 can be used to easily connect the vertical rod 18 and the horizontal plate 19 to the outer frame 1 of the reagent kit 2. The movement of the toothed plate 11 and the vertical rod 18 can be controlled by the control panel 13. At the same time, the position information fed back by the camera 20 to the control panel 13 can realize the automatic adjustment of the position of the horizontal plate 19, which can ensure the positional matching accuracy between the camera 20 and the reagent tube containing the red blood cell suspension as much as possible, thereby ensuring the accuracy of the camera 20 in determining the concentration of the red blood cell suspension in the reagent tube.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
