Description

Automatic retinal film washing machine Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an automatic retinal patch washing device. Background Technology

[0002] In ophthalmic research settings such as retinal immunofluorescence staining experiments, researchers often need to repeatedly wash retinal tissue slices to remove unbound antibodies or impurities, ensuring the accuracy of the fluorescence signal and the clarity of the background. This process typically involves multiple rounds of primary and secondary antibody washing, is cumbersome, and requires extremely high tissue integrity. Because retinal tissue is inherently fragile, improper handling during multiple washes and solution changes can easily lead to mechanical damage and failure. However, existing techniques have some problems:

[0003] First, most existing rinsing processes rely on manual operation and lack automatic injection and drainage mechanisms. The injection and drainage of rinsing solution need to be done manually repeatedly. Especially when there are many sample groups, the workload is large and the efficiency of changing the solution is low, which is not conducive to researchers making efficient use of fragmented time.

[0004] Secondly, the devices generally lack an integrated washing and retinal structure, requiring researchers to individually pick up the rinsed retinal tissue, which is time-consuming and can easily damage the tissue, affecting the reliability and repeatability of the experimental results.

[0005] Therefore, there is an urgent need to design an automatic retinal swab washing device that can solve the above technical problems. Summary of the Invention

[0006] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an automatic retinal slide washing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0008] An automated retinal slide washing apparatus includes a shaker and a washing plate, and further includes:

[0009] Automatic injection and discharge mechanism and integrated washing and retrieval mechanism; wherein:

[0010] The automatic injection and discharge mechanism includes a discharge assembly and an injection assembly that are fixedly installed at the left and right ends of the shaker, respectively, and a connecting discharge structure is opened inside the rinsing plate;

[0011] The washing and scooping integrated mechanism includes a rinsing component and a scooping component that are fixedly installed in the middle of the shaking table.

[0012] Furthermore, the drainage assembly includes a pump groove a that extends through the middle of the upper left wall of the shaker. Through holes a are opened in the upper left and right inner walls of the pump groove a. A drainage pump is fixedly installed in the pump groove a. Drainage hoses are connected to the upper left and right ends of the drainage pump. The other end of the drainage hose on the right side is connected to the rinsing plate through the through hole a.

[0013] Furthermore, the injection assembly includes a pump groove b that penetrates the middle of the upper right wall of the shaker, a through hole b that penetrates the upper left inner wall of the pump groove b, an injection pump that is fixedly installed in the pump groove b, an injection hose that is sleeved and connected to the upper left end of the injection pump and the top wall, and the other end of the injection hose on the left side that is sleeved and connected to the rinsing plate through the through hole b.

[0014] Furthermore, the connecting drainage structure includes a drainage trough and an injection trough respectively penetrating the bottom of the side wall of the rinsing plate hole, a drainage port penetrating the left inner wall of the drainage trough, and an injection port penetrating the right inner wall of the injection trough.

[0015] Furthermore, the rinsing assembly includes an oscillation drive unit and an angle guide unit;

[0016] The oscillation drive unit includes a rinsing tank that extends through the middle of the upper wall of the shaker. A motor slot extends through the upper wall of the rinsing tank. A motor is fixedly installed in the motor slot. A rotating shaft is connected to the upper surface of the motor. A turntable is provided at the top of the rotating shaft. A locking component is provided at the eccentric position on the upper surface of the turntable. A retaining ring is fitted onto the retaining component. A turntable is fixedly installed on the upper end of the retaining ring. Limiting protrusions are provided at the four corners of the upper surface of the turntable.

[0017] The angle guide unit includes slide rail grooves that are horizontally opened in the middle of the front and rear inner walls of the rinsing tank. Limiting grooves are opened through the left and right ends of the front wall of the turntable. Limiting rods are movably inserted in the limiting grooves. Pulleys are provided at the front and rear ends of the limiting rods, and the pulleys are engaged in the slide rail grooves.

[0018] Furthermore, the plate-collecting assembly includes pneumatic pumps that are symmetrically fixedly installed at the front, rear left and right ends of the bottom wall of the turntable. The pneumatic pumps protrude from the outer edge of the front and rear walls of the turntable and are provided with lifting rods. The other end of the lifting rods is fixedly connected to the filter screen frame.

[0019] Furthermore, the shaker is equipped with a display screen, control buttons and a rinsing bottle tank at the front end, and a power cord at the rear end;

[0020] The rinsing bottle tank is equipped with an electric heating element and a movably placed rinsing bottle. The upper end of the rinsing bottle is fitted with an injection hose and connected to the injection pump.

[0021] Compared with the prior art, the beneficial effects of this utility model are mainly reflected in:

[0022] Firstly, compared to existing devices that rely on manual injection and drainage of rinsing solution, which are cumbersome, inefficient, and prone to omissions, this invention fails to meet the simultaneous rinsing needs of multiple sample sets. To address this issue, this utility model presents an automatic retinal slide rinsing device employing an automatic injection and drainage mechanism. By setting up injection and drainage components and combining them with a connected rinsing hole structure, it achieves uniform, precise, and efficient injection and drainage of rinsing solution, significantly improving experimental efficiency and reducing the workload of researchers.

[0023] Secondly, compared to existing devices that require manual removal of retinal tissue one by one, which is difficult to operate and prone to tissue damage, this invention provides an automatic retinal slide washing device that integrates washing and retrieval. By using a liftable filter frame in conjunction with a rotating washing platform, the filter frame can be automatically raised after washing, gently retrieval all retinal slides at once. This avoids the risk of tissue damage from repeated handling, ensuring tissue integrity and the reliability of experimental results.

[0045] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0046] As shown in Figures 1-6, the present invention provides an automatic retinal slide washing apparatus, comprising a shaking table 1 and a washing plate 4, and further comprising:

[0047] Automatic injection and discharge mechanism 2 and integrated washing and retrieval mechanism 3; wherein:

[0048] The automatic injection and discharge mechanism 2 includes a draining component 21 and an injection component 22, which are respectively fixedly installed at the left and right ends of the shaker 1. The draining component 21 and the injection component 22 are used to realize the automatic injection and automatic discharge of rinsing liquid, reduce the frequency of manual operation and improve rinsing efficiency. The rinsing plate 4 has a connecting draining structure 23 inside. The connecting draining structure 23 makes the bottom of each row of rinsing holes connected, which helps the rinsing liquid to be injected and discharged uniformly and evenly distributed and flow uniformly, avoiding local residue.

[0049] The washing and retrieval integrated mechanism 3 includes a rinsing component 31 and a slide retrieval component 32, which are fixedly installed in the middle of the shaker 1. The rinsing component 31 is used to gently rinsing the retinal slide by vibration, while the slide retrieval component 32 performs an automatic retrieval operation after rinsing. The sample is steadily extracted from the rinsing solution by lifting and lowering the filter screen, realizing the integration of the washing and retrieval process. It can also prevent tissue tearing or damage, and greatly improve experimental efficiency and sample integrity.

[0050] As shown in Figures 1, 2, and 3, in this embodiment, the drainage assembly 21 includes a pump groove a211 that penetrates the middle of the upper left wall of the shaker 1. The pump groove a211 provides a fixed installation space for the drainage pump 213, facilitating subsequent maintenance and replacement. Through holes a212 are opened through the upper parts of the left and right inner walls of the pump groove a211. The through holes a212 are used to connect the drainage hose 214, allowing liquid to flow from the rinsing plate 4 into the pump to complete the drainage operation. The drainage pump 213 is fixedly installed in the pump groove a211. The drainage pump 213 is responsible for providing negative pressure to draw the used rinsing liquid out of the hole in the rinsing plate 4 and into the waste liquid container. The upper left and right ends of the drainage pump 213 are both sleeved and connected to the drainage hose 214. The drainage hose 214 is made of flexible material, has good sealing and deformability, and is suitable for dynamic structure installation. The other end of the right drainage hose 214 penetrates the through hole a212 and is sleeved and connected to the rinsing plate 4, directly drawing out the rinsing liquid from the hole in the rinsing plate 4.

[0051] As shown in Figures 1, 2, and 3, in this embodiment, the injection assembly 22 includes a pump groove b221 that penetrates the middle of the upper right wall of the shaker 1. The pump groove b221 is used to install the injection pump 223. The overall structure is symmetrically arranged for easy maintenance and control. A through hole b222 is opened through the upper left inner wall of the pump groove b221. The through hole b222 provides a guide hole for the injection hose 224, allowing the rinsing liquid to flow smoothly into the rinsing plate 4. The injection pump 223 is fixedly installed in the pump groove b221. The pump is responsible for drawing rinsing liquid at a preset temperature from the rinsing bottle 132 and accurately injecting it into each rinsing hole of the rinsing plate 4. The upper left end of the injection pump 223 is connected to the top wall with the injection hose 224. The other end of the left injection hose 224 is connected to the rinsing plate 4 through the through hole b222. The injection hose 224 is tightly connected, ensuring continuous and stable rinsing liquid transportation. It is flexible, corrosion-resistant, and suitable for the transportation of various biochemical rinsing liquids.

[0052] As shown in Figures 1, 5, and 6, in this embodiment, the connecting drainage structure 23 includes a drainage trough 231 that penetrates the bottom of the sidewall of the four holes in the rinsing plate and an injection trough 232 that penetrates the upper part of the sidewall of the holes. The drainage trough 231 is used to guide the waste liquid to quickly collect and flow to the drainage port 233, while the injection trough 232 is used to quickly and evenly distribute the rinsing liquid to each hole during injection. The bottoms of the holes in the same row are connected, the bottoms of the leftmost row of holes are interconnected, and the upper parts of the rightmost row of holes are interconnected. This structure is based on the principle of communicating vessels. The system can simultaneously inject and drain liquid into all holes of the rinsing plate 4. A drain port 233 is opened through the left inner wall of the drain tank 231. The other end of the drain hose 214 on the right side of the pump tank a211 is connected to the drain port 233 through the through hole a212 to form a complete drain passage. A liquid injection port 234 is opened through the right inner wall of the injection tank 232. The other end of the liquid injection hose 224 on the left side of the pump tank b221 is connected to the liquid injection port 234 through the through hole b222 to form a complete liquid injection passage.

[0053] As shown in Figures 1, 4, and 5, in this embodiment, the rinsing assembly 31 includes an oscillation drive unit 311 and an angle guide unit 312. The oscillation drive unit 311 realizes adjustable amplitude and frequency rotational oscillation, which is used to generate eddies in the rinsing liquid within the holes of the rinsing plate 4, thereby achieving a gentle and efficient cleaning effect. The angle guide unit 312 is used to limit the oscillation trajectory and ensure that the turntable 3118 swings slightly in a predetermined direction in the horizontal plane.

[0054] The oscillation drive unit 311 includes a rinsing tank 3111 that extends through the middle of the upper wall of the shaker 1. The rinsing tank 3111 provides a protective space for the entire rinsing process and serves to collect and isolate liquid. A motor slot 3112 extends through the upper wall of the rinsing tank 3111. The motor slot 3112 is used to fix the motor 3113, ensuring its stability and axis alignment during the oscillation process. The motor 3113 is fixedly installed in the motor slot 3112. The motor 3113 is the drive source of this device, providing adjustable speed rotational power to simulate the rinsing action. A rotating shaft 3114 is connected to the upper surface of the motor 3113. The rotating shaft 3114 transmits vertically, transmitting the rotational power of the motor 3113 to the rinsing platform. A turntable 3115 is provided at the top of the rotating shaft 3114. The turntable 3115 lifts the rinsing plate 4. The rotating support structure includes a locking piece 3116 located on the eccentric area of ​​the upper surface of the turntable 3115. The locking piece 3116 forms an eccentric track at the non-central position, which, in conjunction with the movement, simulates slight oscillation and rotation. The locking piece 3116 is fitted with a retaining ring 3117, which ensures that the rotating platform is stably mounted on the drive component and also ensures that the angle of the rotating platform remains unchanged during rotation and oscillation. A turntable 3118 is fixedly mounted on the upper end of the retaining ring 3117. The turntable 3118 is the direct bearing platform of the rinsing plate 4 and works with the turntable 3115 to complete the overall oscillation and rotation. The four corners of the upper surface of the turntable 3118 are provided with limiting protrusions 3119, which limit and prevent slippage of the rinsing plate 4 during oscillation.

[0055] The angle guiding unit 312 includes slide rail grooves 3121 that are horizontally opened in the middle of the front and rear inner walls of the rinsing tank 3111. The slide rail grooves 3121 provide a guiding channel for the turntable 3118 to limit the movement trajectory, so that the oscillation action is kept in a slight rotation in the horizontal direction. Limiting grooves 3122 are opened through the left and right ends of the front wall of the turntable 3118. The limiting grooves 3122 are used to install limiting rods 3123 to control the offset range of the rinsing platform. The limiting rods 3123 are movably inserted in the limiting grooves 3122. The limiting rods 3123 are provided with pulleys 3124 at both the front and rear ends. The pulleys 3124 are engaged in the slide rail grooves 3121. Under the action of the pulleys 3124 and the slide rail grooves 3121, the limiting rods 3123 slide back and forth along a fixed path, which can effectively prevent the turntable 3118 from rotating at an angle, while not affecting the smoothness of the overall oscillation motion.

[0056] As shown in Figures 1, 4, and 5, in this embodiment, the retina tray assembly 32 includes pneumatic pumps 321 symmetrically fixedly installed at the front, rear, left, and right ends of the outer bottom wall of the turntable 3118. The pneumatic pumps 321 can push the lifting rod 322 up and down through controlled air pressure, realizing the lifting and lowering of the filter frame 323. The pneumatic pumps 321 protrude from the outer edge of the front and rear walls of the turntable 3118 and are provided with the lifting rod 322. Under the action of the control signal, the lifting rod 322 makes vertical lifting and lowering movements, driving the filter frame 323 to rise or fall as a whole, which facilitates the retina tray ...

[0057] As shown in Figures 1 and 3, in this embodiment, the front end of the shaker 1 is provided with a display screen 11, control buttons 12 and rinsing bottle tank 13. The display screen 11 can display the current working status, set speed, temperature and other information in real time. The control buttons 12 are used to manually adjust the operating parameters or start and stop the program. The rear end is provided with a power cord 14, which provides stable power to the whole machine. The rear-mounted design helps with wiring and safety management.

[0058] The rinsing bottle tank 13 is equipped with an electric heating element 131 and a movably placed rinsing bottle 132. After heating, the electric heating element 131 can maintain a constant temperature of the rinsing solution, preventing tissue cold stimulation or affecting the reagent reaction efficiency. The upper end of the rinsing bottle 132 is connected to the injection hose 224 and the injection pump 223. The injection path is completely closed, ensuring that the rinsing solution is uncontaminated and the flow rate is stable during the transportation process.

[0059] The working principle and usage process of this technical solution are as follows: During use, the user first starts the device by controlling button 12, and the injection pump 223 starts. The injection pump 223 draws the rinsing solution from the rinsing bottle 132 through the injection hose 224 and injects it into the injection tank 232 of the rinsing plate 4 through the injection port 234. The liquid is automatically and evenly distributed in the structure of the interconnected rinsing holes to form a suitable liquid level to submerge the filter frame 323. Then, the pneumatic pump 321 drives the lifting rod 322 to retract downward, which drives the filter frame 323 to descend into the rinsing solution as a whole, ensuring that the retinal patch inside the filter is completely immersed in the rinsing solution and begins to be rinsed.

[0060] Next, the motor 3113 starts and drives the turntable 3115 to rotate. The motor 3113 drives the eccentric clamp 3116 to rotate through the rotating shaft 3114, causing the clamp ring 3117 and the turntable 3118 to generate gentle oscillations within a controlled range. The rinsing plate 4 on the turntable 3118 then drives the rinsing liquid in the hole to rotate, thereby forming a vortex cleaning environment to achieve gentle cleaning of the retinal patch. The slide rail groove 3121 works in concert with the limiting rod 3123 and the pulley 3124. The pulley 3124 moves along the slide rail groove 3121, limiting the oscillation angle and ensuring that the square turntable 3118 can rotate around the axis without changing the angle.

[0061] After the preset rinsing time is completed, the motor 3113 stops running, and the pneumatic pump 321 drives the lifting rod 322 to rise in the reverse direction. The lifting rod 322 drives the filter frame 323 to rise as a whole. The dense ultra-fine filter grid at the bottom of the filter screen can intercept and support all the grouped retinal patches, so that they can be picked up as a whole at once. At this time, the drain pump 213 starts, and the drain pump 213 discharges the used rinsing solution from the drain tank 231 through the drain port 233 into the waste bottle through the drain hose 214, completing one rinsing cycle.

[0062] Subsequently, the device can automatically start the next round of liquid injection and rinsing process. The system automatically repeats the liquid injection, oscillation rinsing, filter lifting and draining actions according to the preset program to complete the cleaning steps in multiple rounds of immunofluorescence staining, greatly reducing the need for manual operation, while ensuring that each cleaning process is standardized and controllable. Throughout the process, the user can monitor the rotation speed, temperature and operating status of each stage in real time through the front-end display screen 11. The display screen 11 is connected to the internal system and can display the current rinsing solution temperature and the remaining number of rinsing times, and allows the user to pause or adjust parameters at any time to adapt to different experimental needs.

[0063] The present invention has been further described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
