Description

Technical Field

[0001] The present invention relates to the technical field of chemical or physical analysis, and specifically to a smear device for medical detection. Background Art

[0002] Smear detection is a fundamental and crucial detection method. It is widely used in many sub-disciplines such as hematology, microbiology, pathology, etc. By evenly smearing various medical samples (such as blood, sputum, tissue fluid, etc.) on a specific smear plate, the components such as cells and pathogens in the sample can be presented in a relatively dispersed and observable state, and then morphological observation, counting, and related characteristic analysis can be carried out with the help of professional instruments such as microscopes, providing key bases for early screening, accurate diagnosis, and condition monitoring of diseases.

[0017] Beneficial Effects Compared with the prior art, the present invention provides a smear device for medical detection, which has the following beneficial effects: 1. The smear device for medical testing utilizes the setting of the movable component. When the smear is completed, the telescopic cylinder 2 drives the movable block and the smear shaft to move upward and move to fit with the inner side of the cleaning block. At this time, the telescopic plate will be reset under the action of the connecting spring, so that the cleaning block is driven to slide on the surface of the smear shaft toward the surface close to the movable block, and the surface of the used smear shaft is cleaned to prevent the smear shaft from having the sample of the last test remaining on its surface after use, resulting in contamination of the sample, thereby affecting the accuracy of the test result and causing deviation in the test data, thereby improving the accuracy of the test result, and improving the smear quality and test efficiency.

[0018] 2. When the smear device for medical testing uses the movable component to clean the smear shaft, the upward movement of the movable block will drive the connecting block to move upward, and the positioning block will be pulled by the pull plate to move toward the surface close to the smear shaft. When the positioning block moves, it will drive the collection frame to move to the bottom end of the smear shaft and collect the cleaned impurities, so as to prevent the cleaning block from scraping off a lot of impurities when cleaning the smear shaft, affecting the accuracy of the test results, and also destroying the sanitary condition of the entire test area, which does not meet the strict cleaning requirements of medical testing, maintains a clean and sanitary testing environment, and ensures stable and reliable operation of the device.

[0019] 3. The smear device for medical detection is arranged by using a swinging assembly. When the resistance rod moves to the right, it will resist the sliding of the block on the top of the bottom plate. When the block slides, it will first drive the insertion rod on the cam surface to slide at the surface strip groove of the fixed plate. When the insertion rod slides to the inclined groove opened by the fixed plate, it will resist the insertion rod to swing downward. When the insertion rod swings downward, it will drive the rotation of the cam and the rotating rod. When the rotating rod rotates, it will drive the moving frame and the scraper to swing downward and resist the surface of the smear plate to scrape off the stubborn stains adhered to the surface of the smear plate to prevent stubborn stains from remaining on the surface of the smear plate. When the sample smear operation is performed later, these stains may be mixed into the sample and change the original composition and state of the sample. By cleaning the smear plate, the accuracy of the smear detection can be guaranteed and the health and safety of the detection environment can be maintained. BRIEF DESCRIPTION OF THE DRAWINGS

The scraping effect of the scraping plate 710 on the smear plate 52 can be improved by the U-shaped moving frame 79 and the triangular scraping plate 710.

[0030] Working principle: when the smear device for medical detection is used, the detection sample can be dropped onto the smear plate 52 through the dropper 2, and the telescopic cylinder 1 53 is started to drive the moving block 54 to move to the right. When the moving block 54 moves to the right, it is also necessary to start the telescopic cylinder 2 55 to drive the movable block 56 to move downward on the inner side of the moving block 54. When the movable block 56 moves, it will drive the smear shaft 4 set on the inner side to move downward and fit on the smear plate 52 on the top of the machine table 3. When the telescopic cylinder 1 53 is started, it will drive the moving block 54 to move to the right, thereby driving the movement of the smear shaft 4 set on the inner side, so as to smear the sample. When the smear shaft 4 is smeared and rolled at the top of the smear plate 52, the rotation of the smear shaft 4 will drive the rotation of the rotating shaft 57. When the rotating shaft 57 rotates, it will contact the telescopic rod 58 through the arc groove 513 opened on its surface to move close to the center point of the smear shaft 4. When the telescopic rod 58 moves, it will drive the telescopic plate 59 is extended, so that the cleaning block 510 is pushed to move toward the center point of the smear shaft 4. When the smear is completed, the telescopic cylinder 2 55 drives the movable block 56 to move upward, so that the smear shaft 4 is driven upward by the rotating shaft 57, and moves to the inner side of the cleaning block 510 and fits with it. At this time, the telescopic plate 59 will be reset under the action of the connecting spring 512, so that the cleaning block 510 is driven to slide on the surface of the smear shaft 4 toward the surface of the movable block 56. Since the surface of the rotating shaft 57 is provided with an arc groove 513, and there is a certain friction between the rotating shaft 57 and the telescopic rod 58 through the arc groove 513, and the telescopic plate 59 also has a buffering effect of movement when resetting, and the smear shaft 4 is also close to the cleaning block 510 when it rises. For this reason, the movable block 56 will first fit on the bottom end of the cleaning block 510 during the process of driving the smear shaft 4 to rise. For this reason, the activity sequence cleans the surface of the used smear shaft 4. In the detection, the purity of the sample is very important. If there are samples from the previous test remaining on the surface of the smear shaft 4 after use and it is not effectively cleaned, the residual samples may be mixed into the new samples when the smear operation is performed next time, causing the samples to be contaminated, thereby affecting the accuracy of the test results, causing deviations in the test data, and even leading to wrong diagnostic conclusions, misleading subsequent medical judgments and treatment plan formulation, preventing sample cross-contamination and accumulation of stains on the smear shaft 4 that affect the smear quality, thereby improving the accuracy of the test results, and enhancing the smear quality and test efficiency.

[0031] When the movable block 56 moves downward, it will also drive the connecting block 61 to slide downward. When the connecting block 61 slides downward, it will resist the sliding of the positioning block 63 through the pull plate 62. When the positioning block 63 slides, it will drive the collecting frame 64 to move to the left. After the smear is completed, when the movable component 5 cleans the smear shaft 4, the movable block 56 moves upward to drive the connecting block 61 to move upward, and pulls the positioning block 63 to move to the surface close to the smear shaft 4 through the pull plate 62. When the positioning block 63 moves, it will drive the collecting frame 64 to move to the bottom end of the smear shaft 4 and collect the clean impurities to prevent When cleaning the smear shaft 4, the cleaning block 510 will scrape off a lot of impurities, such as residual samples, dust, etc. If there is no collection frame 64 to collect these impurities in time, they will be scattered randomly in the surrounding areas such as the machine 3 and the ground, thereby causing secondary pollution to the detection environment. Once secondary pollution occurs, subsequent detection samples may be contaminated with these scattered impurities, affecting the accuracy of the detection results. At the same time, it will also destroy the sanitary conditions of the entire detection area, which does not meet the strict cleaning requirements of medical testing, maintain the cleanliness of the detection environment, and ensure stable and reliable operation of the device.

[0032] When the moving block 54 moves to the right under the action of the telescopic cylinder 53, it will also drive the resistance rod 78 to move to the right. When the resistance rod 78 moves to the right, it will resist the block 74 from sliding on the top of the bottom plate 73. When the block 74 slides, it will first drive the insertion rod 77 on the surface of the cam 76 to slide in the surface strip groove 711 of the fixed plate 72. When the insertion rod 77 slides to the inclined groove 712 provided in the fixed plate 72, it will resist the insertion rod 77 to swing downward. When the insertion rod 77 swings downward, it will drive the cam 76 to rotate. When the cam 76 rotates, it will drive the rotating rod 75 to rotate. When the rotating rod 75 rotates, it will drive the moving frame 79 to swing downward. When the moving frame 79 swings downward, it will drive the scraper 710 Swing downward and contact the surface of the smear plate 52 to scrape off the stubborn stains adhered to the surface of the smear plate 52 to prevent the stubborn stains from remaining on the surface of the smear plate 52. During the subsequent sample smear operation, these stains may be mixed into the sample, changing the original composition and state of the sample, affecting the uniform smearing of the sample on the smear plate 52, resulting in uneven thickness of the smear, impurity spots, etc., which further interferes with the observation of the cell morphology, structure and other characteristics of the chemical sample under the microscope, reduces the accuracy and reliability of the test, and is not conducive to medical testing personnel to make correct diagnosis judgments. By cleaning the smear plate 52, the accuracy of the smear test can be guaranteed and the health and safety of the testing environment can be maintained.
