Description
Technical Field
[0001] The invention belongs to the technical field of medical equipment, in particular to a medical blood cell staining instrument. Background Art
[0002] Chemical staining of blood cells is a science formed by the combination of cytology and chemistry. The purpose of staining is to dye the main structures of cells, such as cytoplasm, nucleus, organelles, etc., with different colors for easy observation under a microscope. It is based on cell morphology and combines the principles of chemical reactions to conduct qualitative, localized, and semi-quantitative analysis of various chemical substances in blood cells. This type of method is helpful for understanding the normal physiological functions of blood cells, the diagnosis and differential diagnosis of certain blood diseases, the efficacy and prognosis of treatment, and is also of certain significance for the exploration of the pathogenesis.
[0003] When the existing equipment uses Wright dye to stain blood cells, the glass slide needs to be placed horizontally and the dye needs to be added. During cleaning, water will remain on the horizontally placed glass slide. If the remaining water cannot be cleaned and dried in time, the stained area will be discolored, making the staining effect worse. At the same time, when the dye is added, the dye is unevenly distributed and cannot completely cover the area to be stained. During flushing, the flushing effect in the area where the water flow is concentrated is greater than that in the area where the water flow is small, resulting in uneven staining.
[0004] In view of this, the present invention solves the above technical problems by proposing a medical blood cell staining instrument. Summary of the invention
[0005] In order to make up for the shortcomings of the existing technology, the problem is that in the existing medical blood cell staining instrument, water will remain on the horizontally placed glass slide during the flushing process. If the remaining water cannot be cleaned and dried in time, the stained area will be discolored, making the dyeing effect worse. At the same time, when the dye solution is added, the dye is unevenly distributed and cannot completely cover the area to be dyed. When flushing, the flushing effect in the area where the water flow is concentrated is greater than that in the area where the water flow is small, resulting in uneven dyeing.
[0006] The technical solution adopted by the present invention to solve its technical problems is: a medical blood cell staining instrument, comprising a base, a staining mechanism and a glass slide; the staining mechanism comprises a mounting block, a support rod, a rotating plate and a dropper, the mounting block is arranged on one side of the base, the rotating plate is arranged above the mounting block, the rotating plate and the mounting block are connected by the support rod, and the dropper is fixed on the rotating plate; a working groove is arranged on the upper surface of the base, a water inlet pipe is arranged in the side wall of the working groove close to the mounting block, a No. 1 valve is arranged on the water inlet pipe, one end of the water inlet pipe is connected to the working groove, and the other end passes through the bottom of the base and is connected to the external water supply mechanism, a drainage plate is arranged on the side wall of the working groove close to the water inlet pipe, the height of the drainage plate corresponds to the water inlet pipe, the bottom surface of the working groove is inclined and the height of the side close to the water inlet pipe is higher than the height of the side away from the water inlet pipe, a workbench is arranged above the bottom surface of the working groove, the workbench is rectangular, and the workbench and the working groove are connected by four lifting rods, and the lifting rods are respectively located at the four corners of the workbench The lifting rod is fixedly connected to the working groove at the corresponding position of the angle, and the two lifting rods near the water inlet pipe are rotatably connected to the working table, and the connection mode of the two lifting rods away from the water inlet pipe and the working table is contact, and the two sides of the working table bulge upward to form a boss, and a No. 1 clamping block is provided on the side wall of the boss on one side of the working table close to the dropper, and a telescopic rod is evenly provided on the side wall of the boss on the other side of the working table close to the dropper, and a spring is wrapped around the outer side of the telescopic rod, and a No. 2 clamping block is fixedly connected to the side of the telescopic rod away from the boss, one end of the spring is connected to the boss, and the other end is connected to the No. 2 clamping block, a glass slide is clamped between the No. 1 clamping block and the No. 2 clamping block, and the connection point between the water inlet pipe and the working groove is higher than the height of the glass slide; a No. 1 drain pipe is provided in the side wall of the working groove away from the water inlet pipe, one end of the No. 1 drain pipe is connected to the position near the bottom of the side wall of the working groove, and the other end passes through the lower surface of the base, and a No. 2 valve is provided on the No. 1 drain pipe; a ventilation pipe is provided in the side wall of the base provided with the No. 1 drain pipe
[0007] When working, now install all components, rotate the rotating plate to make the dropper away from the top of the working groove of the base, compress the No. 2 clamping block toward the boss, put in the glass slide to be stained, loosen the No. 2 clamping block, make one end of the glass slide against the No. 1 clamping block, and the other end is clamped by the No. 2 clamping block to complete the installation of the glass slide. At this time, adjust the height of the four lifting rods to keep the glass slide horizontal. At this time, rotate the rotating plate again to make the dropper face the position where the glass slide needs to be stained, open the valve in the dropper, let the staining liquid drip onto the glass slide, and stain the blood cells. At this time, the irregular extension and contraction of the four lifting rods make the glass slide shake, guide the staining liquid dripped in the center of the glass slide to flow around, and ensure that the staining liquid completely covers the staining area. The lifting range of the lifting rod is small to ensure that the staining liquid will not flow out of the glass slide. After the dye is evenly covered, the lifting rod stops extending and retracting to keep the glass slide horizontal; after the dyeing is completed, open the No. 1 valve on the water inlet pipe, and water slowly flows from the water inlet pipe into the drainage plate, guiding the water to the top of the glass slide. At this time, adjust the lifting rod again to make the glass slide higher near the water inlet pipe, and the water flow washes the excess dye on the glass slide, and carries the dye along the upper surface of the glass slide to the working tank. At this time, the No. 2 valve on the No. 1 drain pipe is in an open state, and the water is discharged from the No. 1 drain pipe; after the flushing is completed, hot air is introduced into the ventilation pipe, and the lifting rod is adjusted so that the hot air can dry the glass slide at different angles, and finally the dyeing of the glass slide is completed; the lifting rod is an existing electric telescopic rod, and the lifting height is controlled by a controller. The maximum extension distance of the lifting rod will not cause the workbench to fall off the lifting rod.
[0008] Preferably, the base is provided with a No. 1 drain pipe on the side wall thereof, wherein a No. 2 drain pipe is provided inside; one end of the No. 2 drain pipe is connected to the working tank, and the height of the connection point is higher than the height of the glass slide; and the other end of the No. 2 drain pipe is connected to the No. 1 drain pipe.
[0009] During operation, when the staining is too dark, the staining of the glass slide needs to be diluted. At this time, close valve No. 2, and the water inlet pipe will let water into the working tank. When the liquid level submerges the glass slide, continue to let water in. When the liquid level rises to the corresponding position of drain pipe No. 2, excess water will flow into drain pipe No. 2 and be discharged. Water can be let in and drained at the same time, which can improve the fluidity of water in the working tank and is conducive to diluting the staining. After completion, open valve No. 2 to drain the water in the working tank; the other end of drain pipe No. 2 is connected to drain pipe No. 1, so that drain pipe No. 2 and drain pipe No. 1 share a section of pipe, which simplifies the structure and is more convenient and simpler to process during subsequent cleaning and maintenance of the equipment.
[0010] Preferably, one end of the ventilation pipe is connected to the No. 2 drainage pipe, and the other end is inclined upward and connected to the outer surface of the base.
[0011] During operation, one end of the ventilation pipe is connected to the No. 2 drain pipe. After the water in the working tank is drained, the wind is blown into the working tank through the No. 2 drain pipe through the ventilation pipe to dry the glass slides. At the same time, the equipment can also be dried when the equipment is not working to ensure that the equipment is dry and prevent rust and aging. The other end of the ventilation pipe is tilted upward and connected to the outer surface of the base to prevent water from entering the ventilation pipe when the No. 2 drain pipe is drained, and affecting the outer ventilation equipment; the No. 1 drain pipe, the No. 2 drain pipe and the ventilation pipe are connected, and the No. 1 drain pipe and the No. 2 drain pipe can be dried while the ventilation pipe is ventilated to dry the glass slides, so that the No. 1 drain pipe and the No. 2 drain pipe are prevented from rusting and contaminating the clean water for cleaning the glass slides after long-term work, affecting the staining effect.
[0012] Preferably, a trumpet-shaped air outlet is provided on the side wall of the working tank close to the No. 2 drain pipe, the small end of the air outlet is correspondingly connected to the No. 2 drain pipe, and the large end of the air outlet faces the glass slide.
[0013] During operation, an air vent is arranged at a position corresponding to the side wall of the working trough and the No. 2 drain pipe. The air vent is trumpet-shaped, and the small end of the air vent is connected to the No. 2 drain pipe. When the ventilation pipe is ventilated, the effective area becomes larger after the wind passes through the air vent, which can blow the glass slide more evenly. At the same time, the large end of the air vent faces the glass slide, which can make the wind blow more concentratedly to the area where the glass slide is located, which is beneficial to improving the air drying efficiency.
[0014] Preferably, bumps are evenly arranged on the upper surface of the workbench, the bumps are conical, and the tips of the bumps are in contact with the glass slide.
[0015] When working, bumps are evenly arranged on the upper surface of the workbench. The glass slide is placed on the bumps during installation. The bumps are cone-shaped. The tip of the bump contacts the glass slide. The tip of the bump is made of rubber to prevent the tip from scratching the glass slide. The tip contacts the glass slide, and the glass slide and the bumps are point contact. When washing the glass slide, some water adheres to the lower surface of the glass slide, and the lower surface of the glass slide is always in a wet state, which is not conducive to placing the glass slide in other equipment in subsequent research and affects the experimental detection effect. The gaps between the bumps are conducive to part of the wind entering between the glass slide and the workbench when air-drying the glass slide, thereby achieving the effect of air-drying the lower surface of the glass slide and the workbench.
[0016] Preferably, the upper surface of the workbench is an inclined surface, the inclination direction is consistent with the lower surface of the working groove, and the height of the protrusion close to the air outlet is greater than the height of the protrusion away from the air outlet.
[0017] During operation, when the dyeing liquid is added, the glass slide is in a horizontal state. If too much dyeing liquid is added, the excess dyeing liquid will drip onto the workbench, and the dyeing liquid can flow into the working tank along the inclined workbench. After the glass slide is washed, the side of the protrusion away from the air outlet is smaller, and the side close to the air outlet is larger, which increases the distance between the glass slide and the workbench on the side close to the air inlet, allowing more wind to enter between the glass slide and the workbench, thereby improving the air-drying effect; at the same time, the distance between the glass slide and the workbench gradually decreases, thereby increasing the movement speed of the wind, and increasing the air flow speed in the entire device, so that the glass slide can be air-dried more evenly.
[0018] Preferably, a drainage groove is provided on the drainage plate, and the drainage groove includes a main path and a branch path. One end of the main path faces the water inlet pipe, and the other end is divided into a group of branches, and the branches extend to the end of the drainage plate away from the water inlet pipe.
[0019] During operation, when it is necessary to rinse the glass slide, water enters the main channel on the drainage plate from the water inlet pipe, and then flows from the main channel to each branch channel, and then rinses on the glass slide. When the water flow from the main channel flows into the branch channel, the kinetic energy of the water flow is lost due to the bends in the branch channel, so that the water flow is slower during the final rinse, ensuring that the water flow does not damage the blood cells. At the same time, the area that can be rinsed by multiple branches is larger than the staining area of the glass slide, ensuring a more uniform rinse and preventing the staining solution from not being rinsed away, affecting subsequent experiments.
[0020] Preferably, the lower end surface of the guide plate is a curved surface.
[0021] During operation, when air drying, when hot air blows out from the protrusion, the hot air will take away the water vapor on the lower surface of the glass slide and the workbench. The lower surface of the guide plate is a curved surface, which can guide the hot air to flow downward to prevent the water vapor contained in the hot air from hitting the upper surface of the glass slide and re-condensing, affecting the drying effect of the glass slide. At the same time, most of the hot air is guided between the workbench and the working tank, which can air-dry the lifting rod, workbench and working tank, prevent the equipment from rusting and aging in a long-term humid environment, and increase the service life of the equipment.
[0022] The beneficial effects of the present invention are as follows:
[0023] 1. The medical blood cell staining instrument described in the present invention, by arranging a working tank, a clamping device, a workbench, a lifting rod, a water inlet pipe and a No. 1 drain pipe, can realize that during staining, the glass slide is placed horizontally, and during cleaning, the glass slide is placed obliquely, which can not only achieve no waste of dye during staining, but also ensure that there is no water residue on the surface of the glass slide during cleaning, thereby ensuring the staining quality.
[0024] 2. The medical blood cell staining instrument described in the present invention, by providing a No. 2 valve and a No. 2 drain pipe, can achieve dilution of the staining by immersion when the staining is too dark; by providing a ventilation pipe, an air vent and a bump, the glass slide can be efficiently and quickly air-dried after the glass slide is cleaned, thereby improving work efficiency; at the same time, the ventilation pipe is connected to the drain pipe, which can dry the drain pipe, prevent the drain pipe from rusting, and increase the service life of the equipment.

The bottom surface of the working tank 11 is inclined and the height of the side close to the water inlet pipe 12 is higher than the height of the side away from the water inlet pipe 12. A workbench 13 is provided above the bottom surface of the working tank 11. The workbench 13 is rectangular. The workbench 13 is connected to the working tank 11 by four lifting rods 18. The lifting rods 18 are respectively located at the corresponding positions of the four corners of the workbench 13. The lifting rods 18 are connected to the working tank 11. The groove 11 is fixedly connected, the two lifting rods 18 close to the water inlet pipe 12 are rotatably connected to the workbench 13, and the two lifting rods 18 far away from the water inlet pipe 12 are connected to the workbench 13 in a contact manner.

[0035] When working, now all components are installed, rotate the rotating plate 23 to make the dropper 24 away from the working groove 11 of the base 1, compress the No. 2 clamping block 135 towards the boss 131, put in the glass slide 3 to be stained, loosen the No. 2 clamping block 135, so that one end of the glass slide 3 is against the No. 1 clamping block 132, and the other end is clamped by the No. 2 clamping block 135, and the installation of the glass slide 3 is completed. At this time, the height of the four lifting rods 18 is adjusted to keep the glass slide 3 horizontal. At this time, the rotating plate 23 is rotated again to make the dropper 24 face the position where the glass slide 3 needs to be stained, open the valve in the dropper 24, and let the staining liquid drip onto the glass slide 3 to stain the blood cells. At this time, the irregular extension and contraction of the four lifting rods 18 causes the glass slide 3 to shake, guiding the staining liquid dripped in the center of the glass slide 3 to flow around, ensuring that the staining liquid completely covers the staining area, and the lifting amplitude of the lifting rod 18 is small to ensure that the staining liquid does not flow out of the glass slide 3, and wait After the dye is evenly covered, the lifting rod 18 stops extending and retracting to keep the glass slide 3 horizontal; after dyeing is completed, the No. 1 valve 121 on the water inlet pipe 12 is opened, and water slowly flows from the water inlet pipe 12 into the guide plate 4, guiding the water to the top of the glass slide 3.

At this time, the No. 2 valve 141 on the No. 1 drain pipe 14 is in an open state, and water is discharged from the No. 1 drain pipe 14; after flushing is completed, hot air is introduced into the ventilation pipe 15, and the lifting rod 18 is adjusted so that the hot air can dry the glass slide 3 at different angles, and finally the dyeing of the glass slide 3 is completed; the lifting rod 18 is an existing electric telescopic rod, and the lifting height is controlled by a controller. The maximum telescopic distance of the lifting rod 18 will not cause the workbench 13 to fall off the lifting rod 18.
[0036] As a specific embodiment of the present invention, the base 1 is provided with a No. 1 drain pipe 14, and a No. 2 drain pipe 16 is provided in the side wall thereof. One end of the No. 2 drain pipe 16 is connected to the working tank 11, and the height of the connection point is higher than the height of the glass slide 3. The other end of the No. 2 drain pipe 16 is connected to the No. 1 drain pipe 14.
[0037] During operation, when the staining is too dark, the staining of the glass slide 3 needs to be diluted. At this time, the No. 2 valve 141 is closed, and the water inlet pipe 12 allows water to flow into the working tank 11. When the liquid level submerges the glass slide 3, water can continue to flow in. When the liquid level rises to the corresponding position of the No. 2 drain pipe 16, excess water will flow into the No. 2 drain pipe 16 and be discharged, so that water can be drained while flowing in, which can improve the fluidity of the water in the working tank 11 and is conducive to diluting the staining. After completion, the No. 2 valve 141 is opened to drain the water in the working tank 11; the other end of the No. 2 drain pipe 16 is connected to the No. 1 drain pipe 14, so that the No. 2 drain pipe 16 and the No. 1 drain pipe 14 share a section of the pipeline, which simplifies the structure and is more convenient and simpler to process during subsequent cleaning and maintenance of the equipment.
[0038] As a specific implementation of the present invention, one end of the ventilation pipe 15 is connected to the No. 2 drainage pipe 16 , and the other end is inclined upward and connected to the outer surface of the base 1 .
[0039] During operation, one end of the ventilation pipe 15 is connected to the No. 2 drain pipe 16. When the water in the working tank 11 is drained, the wind is blown into the working tank 11 through the No. 2 drain pipe 16 through the ventilation pipe 15 to dry the glass slide 3. At the same time, the equipment can also be dried when the equipment is not working to ensure that the equipment is dry and prevent rust and aging. The other end of the ventilation pipe 15 is tilted upward and connected to the outer surface of the base 1 to prevent water from entering the ventilation pipe 15 when the No. 2 drain pipe 16 is drained, thereby affecting the outer ventilation equipment; the No. 1 drain pipe 14, the No. 2 drain pipe 16 and the ventilation pipe 15 are connected, and the No. 1 drain pipe 14 and the No. 2 drain pipe 16 can be dried while the ventilation pipe 15 is ventilated to dry the glass slide 3, thereby preventing the No. 1 drain pipe 14 and the No. 2 drain pipe 16 from rusting and contaminating the clean water for cleaning the glass slide 3 after long-term work, thereby affecting the dyeing effect.
[0040] As a specific embodiment of the present invention, a trumpet-shaped air outlet 17 is provided on the side wall of the working tank 11 close to the No. 2 drainage pipe 16, the small end of the air outlet 17 is correspondingly connected to the No. 2 drainage pipe 16, and the large end of the air outlet 17 faces the glass slide 3.
[0041] During operation, an air vent 17 is arranged at a position corresponding to the side wall of the working groove 11 and the No. 2 drain pipe 16. The air vent 17 is trumpet-shaped, and the small end of the air vent 17 is connected to the No. 2 drain pipe 16. When the ventilation pipe 15 is ventilated, the wind passes through the air vent 17, and the effective area becomes larger, so that the glass slide 3 can be blown more evenly. At the same time, the large end of the air vent 17 faces the glass slide 3, so that the wind direction can be more concentrated to the area where the glass slide 3 is located, which is beneficial to improving the air drying efficiency.
[0042] As a specific implementation of the present invention, bumps 136 are evenly arranged on the upper surface of the workbench 13 . The bumps 136 are conical in shape, and the tips of the bumps 136 are in contact with the glass slide 3 .
[0043] During operation, bumps 136 are evenly arranged on the upper surface of the workbench 13. The glass slide 3 is placed on the bumps 136 during installation. The bumps 136 are conical in shape. The tip of the bump 136 contacts the glass slide 3. The tip of the bump 136 is made of rubber to prevent the tip from scratching the glass slide 3. The tip contacts the glass slide 3, and the glass slide 3 and the bumps 136 are in point contact. When the glass slide 3 is rinsed, part of the water adheres to the lower surface of the glass slide 3, and the lower surface of the glass slide 3 is always in a wet state, which is not conducive to placing the glass slide 3 in other equipment in subsequent research and affecting the experimental detection effect. The gaps between the bumps 136 are conducive to part of the wind entering between the glass slide 3 and the workbench 13 when the glass slide 3 is air-dried, thereby achieving the effect of air-drying the lower surface of the glass slide 3 and the workbench 13.
[0044] As a specific embodiment of the present invention, the upper surface of the workbench 13 is an inclined surface, the inclination direction is consistent with the lower surface of the working groove 11, and the height of the protrusion 136 close to the air outlet 17 is greater than the height of the protrusion 136 away from the air outlet 17.
[0045] During operation, when the dyeing liquid is dripped, the glass slide 3 is in a horizontal state. If too much dyeing liquid is dripped, the excess dyeing liquid drips onto the workbench 13, and the dyeing liquid can flow into the working tank 11 along the inclined workbench 13. After the glass slide 3 is washed, the side of the protrusion 136 away from the air inlet 17 is smaller, and the side close to the air inlet 17 is larger, which increases the distance between the glass slide 3 and the workbench 13 on the side close to the air inlet 17, so that more wind enters between the glass slide 3 and the workbench 13, and the air-drying effect is improved; at the same time, the distance between the glass slide 3 and the workbench 13 gradually decreases, which increases the movement speed of the wind, increases the air flow speed in the entire device, and makes the glass slide 3 dry more evenly.
[0046] As a specific embodiment of the present invention, a drainage groove is provided on the drainage plate 4, and the drainage groove includes a main path 41 and a branch path 42. One end of the main path 41 faces the water inlet pipe 12, and the other end is divided into a group of branches 42. The branches 42 extend to the end of the drainage plate 4 away from the water inlet pipe 12.
[0047] During operation, when it is necessary to rinse the glass slide 3, water enters the main path 41 on the drainage plate 4 from the water inlet pipe 12, and then flows from the main path 41 to each branch path 42, and then rinses on the glass slide 3. When the water flow of the main path 41 flows into the branch path 42, because the branch path 42 is bent, the kinetic energy of the water flow is lost, so that the water flow is slower during the final rinse, ensuring that the water flow does not damage the blood cells. At the same time, the area that can be rinsed by multiple branches 42 is larger than the staining area of the glass slide 3, ensuring a more uniform rinse, and preventing the staining liquid from not being rinsed, affecting subsequent experiments.
[0048] As a specific implementation of the present invention, the lower end surface of the guide plate 4 is a curved surface 43 .
[0049] During operation, when air drying, when hot air is blown out from the protrusion 136, the hot air will take away the water vapor on the lower surface of the glass slide 3 and the workbench 13. The lower surface of the guide plate 4 is a curved surface 43, which can guide the hot air to flow downward to prevent the water vapor contained in the hot air from hitting the upper surface of the glass slide 3 and re-condensing, thereby affecting the drying effect of the glass slide 3. At the same time, most of the hot air is guided between the workbench 13 and the working tank 11, so as to air dry the lifting rod 18, the workbench 13 and the working tank 11, thereby preventing the equipment from rusting and aging in a long-term humid environment and improving the service life of the equipment.
[0050] The specific workflow is as follows:
[0051] Now that all components have been installed, rotate the rotating plate 23 to move the dropper 24 away from the top of the working groove 11 of the base 1, compress the No. 2 clamping block 135 toward the boss 131, put in the glass slide 3 to be stained, loosen the No. 2 clamping block 135, make one end of the glass slide 3 rest on the No. 1 clamping block 132, and the other end is clamped by the No. 2 clamping block 135, and the installation of the glass slide 3 is completed. At this time, adjust the height of the four lifting rods 18 to keep the glass slide 3 horizontal, and then rotate the rotating plate 23 again to make the dropper 24 face the position of the glass slide 3 that needs to be stained, open the valve in the dropper 24, and let the staining liquid drip onto the glass slide 3 to stain the blood cells. At this time, the irregular expansion and contraction of the four lifting rods 18 cause the glass slide 3 to shake, and guide the staining liquid dripped in the center of the glass slide 3 to flow around, ensuring that the staining liquid completely covers the staining area In the above-mentioned embodiment, the lifting range of the lifting rod 18 is small, so as to ensure that the dye does not flow out of the glass slide 3. After the dye is evenly covered, the lifting rod 18 stops extending and retracting to keep the glass slide 3 horizontal. After the dye is evenly covered, the No. 1 valve 121 on the water inlet pipe 12 is opened, and water slowly flows from the water inlet pipe 12 into the guide plate 4 to guide the water above the glass slide 3. At this time, the lifting rod 18 is adjusted again to make the glass slide 3 closer to the water inlet pipe 12 higher. The water flow washes away the excess dye on the glass slide 3 and carries the dye along the upper surface of the glass slide 3 into the working tank 11. At this time, the No. 2 valve 141 on the No. 1 drain pipe 14 is in an open state, and the water is discharged from the No. 1 drain pipe 14. After the flushing is completed, hot air is introduced into the ventilation pipe 15, and the lifting rod 18 is adjusted so that the hot air can dry the glass slide 3 at different angles, and finally the dyeing of the glass slide 3 is completed.
