Abstract
Description
Technical Field
[0001] The invention relates to the technical field of biological instruments, and in particular to a sample smear continuous feeding device for clinical testing. Background Art
[0002] A continuous feeding device for sample smears used for clinical testing is used in the biological and medical fields. Traditional sample preparation generally involves manually extracting glass slides and manually making smears from samples. However, this method requires high operator skills and is inefficient, and is not suitable for the preparation of large quantities of samples. In order to improve the efficiency of batch production and realize full automation of the production process, a device that can automatically feed glass slides and make sample smears is particularly important.
[0003] Patent document CN212831488F disclosed a glass substrate conveying mechanism on the announcement date of March 30, 2023, and its technical solution includes: a conveying device, a cleaning device and a drying device. The conveying device is located on a support column, and the conveying device includes a conveyor belt. A fixed plate is provided on the conveyor belt, and a positioning column cooperating with the fixed plate is provided on the conveyor belt. During transportation, the glass substrate is fixed to enhance the stability of the device. As the glass substrate is conveyed, water is sprayed from the water spray hole to rinse the surface of the glass substrate. After rinsing, a soft brush is used to clean it. Hot gas is sprayed from the air jet hole to dry the glass substrate. The water flowing to the conveyor belt passes through a water pump and is returned to the water tank through a water filter. Cleaning and drying are achieved during the conveying process, which improves work efficiency. In this way, glass foam is not easily generated during the conveying process, thereby protecting the environment.
[0004] As in the prior art of the above-mentioned patent, the substrate is directly fixed to increase its stability on the conveyor belt. However, during the coating and transportation of the sample slide, the coated sample needs to be transported to a storage device. Direct fixation makes it difficult to separate the slide, which makes the subsequent processing procedures cumbersome. At the same time, when coating the slide sample, the scraper needs to be adjusted in angle to ensure that the sample on the slide is evenly coated. Otherwise, it will make it difficult to observe the sample cells. Therefore, a sample smear continuous feeding device for clinical testing is urgently needed to solve the above problems.

[0060] The angle between the transmission gear set 46 and the horizontal line is about 60°. This method can make the upper and lower gear rods 45 move in parallel with each other. At the same time, with the buffer spring 47, the coated sample can be quickly transported to the sample conveyor belt. At the same time, each pushing component is driven separately, so that multiple samples can be transported and classified to avoid contamination and interference between samples.
[0061] A sample conveyor belt 18 is disposed on the support base 1 , and a driving motor is disposed on the sample conveyor belt 18 . A sample storage box 11 is disposed on one side of the support base 1 , and an air-drying component 10 is disposed on the support base 1 .
[0062] The air-drying component 10 is mainly used for quickly air-drying the coated glass slide, so as to quickly fix the cells in the sample and facilitate the later observation of the glass slide. A classification component is arranged in the sample storage box 11, and the purpose of storing the same type of samples is achieved through the transportation of the sample conveyor belt 18. At the same time, a pushing mechanism is arranged on the rear side of the sample storage box 11, so as to quickly take out the coated sample in the sample storage box 11 and facilitate the subsequent sample observation experiment.
[0063] In the present invention, a sample smear continuous feeding device for clinical testing has the following specific operating steps:
[0064] When transporting the glass slides, start the motor 12 and the suction pump 5, use the suction cup 19 to absorb the glass slides on the glass slide supply belt 13, and then push the suction pump 5 through the hydraulic rod to move it on the limit rod 15, and place the glass slide on the pressing plate 35 on the conveyor belt 9. At the same time, the driving end of the motor 12 drives the conveyor belt 9 to run through the bevel gear set 14;
[0065] During the glass slide titration, when the glass slide is transported to the bottom of the bracket 6, the electric push rod 7 pulls the piston rod 20 to move, and the sample in the sample storage tank 8 is extracted into the injection tube 23 through the one-way tube 38. The large disc on the movable valve 39 covers all the discharge holes. At the same time, the compression spring 40 squeezes the large disc under the action of the small disc, thereby reducing the air from The discharge hole enters and reducing the possibility of bubbles generated inside the injection tube 23. When the piston rod 20 moves downward, the large disc on the movable valve 39 squeezes the compression spring 40 against the sample, so that the discharge hole opens, and the injection tube 23 starts to discharge, and the sample is titrated onto the glass slide.
[0066] When the glass slide is coated, when the piston rod 20 moves, the piston rod 20 drives the one-way shaft gear 22 through the spur gear set 21 to drive another spur gear set 21 to rotate, and the other spur gear set 21 drives the toothed plate column 26 to move upward, and the toothed plate column 26 pulls the scraper 30 on the fixed rod 28 to rotate a certain angle through the pull rod 27. At the same time, the reset plate 25 squeezes the reset spring 24, and the telescopic hook 29 is squeezed and contacted with the conveyor belt 9. When the pressure plate 35 is transported to the bottom of the scraper 30, the telescopic hook 29 fits with the notch on the pressure plate 35. The pressure plate 35 is subjected to the squeezing force through the seesaw 37, so that the limit block 32 bulges, limits the glass slide, and prevents the glass slide from sliding. When the glass slide leaves the area where the scraper 30 is located, the reset spring 24 drives the toothed plate column 26 and the scraper 30 to reset, and the telescopic hook 29 separates from the notch and resets, thereby resetting the limit block 32.
[0067] When the coated glass slides are classified and stored, the conveyor belt 19 drives the conveyor belt 2 16 to rotate through the bevel gear set 2 17, and the conveyor belt 19 transports the coated glass slides to the cache component 42, and the cache component 42 is driven by the conveyor belt 2 16 to be transported to the other side. At the same time, the motor 3 is started, and the motor 3 drives the transmission gear set 46 to drive the gear rods 45 on both sides to move. The gear rods 45 push the loading plate 44 to the bottom of the cache component 42, and the cache component 42 places the glass slide on the loading plate 44, and then the gear rod 45 continues to push the loading plate 44, and the buffer spring 47 at the front end of the loading plate 44 is squeezed, and the upper gear rod 45 pushes the glass slide to fall onto the sample conveyor belt 18, and then the drive motor is started to transport the glass slide to the sample storage box.
