Description

Technical Field

[0001] This invention relates to the field of biomedical engineering technology, specifically to a waste suction head recycling device. Background Technology

[0002] Fully automated chemiluminescence immunoassay analyzers are one of the core testing devices in the biomedical engineering industry, widely used in clinical diagnosis, drug analysis, food safety, and environmental monitoring. This instrument combines highly sensitive chemiluminescence assay technology with highly specific immunoreaction, enabling precise quantitative detection of trace amounts of various antigens, antibodies, hormones, enzymes, vitamins, and drugs. It boasts significant advantages such as high sensitivity, strong specificity, wide detection range, stable labeling, and long reagent shelf life, making it an indispensable analytical tool in modern medical testing and life science research.

[0003] In practical use, the fully automated chemiluminescence immunoassay analyzer uses a pipette to transfer reagents and samples. After each pipetting operation, the used disposable pipette tip needs to be removed from the pipette for the next sampling. The removed waste pipette tip falls into the collection container, completing the recycling process.

[0004] However, when the removed pipette tip falls into the collection container, the residual liquid adhering to the inner wall of the tip is easily splashed by the impact between the tip and the collection container, and quickly forms aerosol particles that can be suspended in the air. These aerosols may contain corrosive chemical reagents, pathogenic microorganisms, DNA samples, or other harmful substances. The rapid diffusion of aerosols can contaminate experimental samples, seriously affecting the accuracy and reliability of test results. It may also cause cross-infection and biosafety accidents, threatening the health of operators, while increasing the cost of repeated experiments and cleaning and disinfection, thus having an adverse impact on the biomedical engineering industry. Summary of the Invention

[0005] The purpose of this invention is to provide a waste suction head recycling device to solve the problems mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A waste pipette tip recycling device includes a recycling component disposed within a chemiluminescence immunoassay analyzer, the recycling component comprising: The collection box has fixed partitions inside. An inclined plate is fixedly installed on one side of the collection box. The inclined plate is provided with multiple slides, and a conical hole is provided at the bottom end of the slides on the inclined plate to turn the suction head from an inclined state to a vertical state. A slide is horizontally slidably connected inside a collection box. A top cover for opening or closing the collection box is fixedly installed on the top of the slide. When the slide moves to close the top cover, a sealed isolation is formed between the bottom of the slide and the inclined plate. A clamping mechanism, vertically slidably connected to the carriage, is used to clamp the suction head; the clamping mechanism includes a sliding rod for driving. A guide slot seat is fixedly installed on one side of the collection box. The guide slot seat has a P-shaped guide slot. The slide rod is slidably engaged in the guide slot. The guide slot has multiple transition slopes. When the slide rod passes through the transition slopes, the clamping mechanism performs clamping or releasing actions. A rotating shaft is rotatably mounted on a guide groove seat. A telescopic rod is provided on the rotating shaft, and one end of the telescopic rod is sleeved on the outside of the slide rod. An air guide shroud is fixed to one side of the collection box, and a fan is installed inside the air guide shroud.

[0007] In a preferred embodiment of the waste suction head recycling device of the present invention, the partition divides the collection box into a waste liquid collection section and a suction head collection section, wherein the waste liquid collection section is located directly below the conical hole.

[0008] In a preferred embodiment of the waste suction head recycling device of the present invention, the telescopic rod includes a cylinder fixed to the outside of the rotating shaft and a rod with one end slidingly extending into the cylinder, and a third spring is fixedly connected between the inside of the rod and the bottom surface of the cylinder.

[0009] In a preferred embodiment of the waste suction head recycling device of the present invention, a baffle is fixed on the side of the bottom of the inclined plate away from the slide, and when the slide moves to close the top cover, the bottom of the slide and the top of the baffle form a seal.

[0010] In a preferred embodiment of the waste suction head recycling device of the present invention, a filter is fixed at the inlet of the air guide shroud.

[0011] As a preferred embodiment of the waste suction head recycling device of the present invention, the length of the top cover is less than the length of the top opening of the collection box, and the slide is provided with a through hole. When the top cover closes the upper part of the inclined plate, a gap is formed between the other end of the top cover and the collection box to communicate with the outside, which is used to form an airflow channel when the fan is sucking.

[0012] As a preferred embodiment of the waste suction head recycling device of the present invention, the clamping mechanism further includes a clamping seat, in which multiple sets of clamping claws slide symmetrically, and a second spring is connected between each set of clamping claws. The clamping seat is provided with multiple sliding grooves, and sliders are slidably connected in each of the multiple sliding grooves. Each slider is rotatably connected to two corresponding clamping claws on both sides.

[0013] As a preferred embodiment of the waste suction head recycling device of the present invention, a push rod is slidably connected inside the clamping seat, the slide rod is fixed to one end of the push rod, a first spring is fixedly connected between the other end of the push rod and the inside of the clamping seat, the push rod is provided with multiple guide slopes, and the ends of multiple sliders are provided with chamfers that slide in cooperation with the guide slopes.

[0014] In a preferred embodiment of the waste suction head recycling device of the present invention, the guide groove on the guide groove seat includes a first guide groove, a second guide groove, a third guide groove, a fourth guide groove and a fifth guide groove connected in sequence, and the end of the fifth guide groove is connected to the connection between the first guide groove and the second guide groove.

[0015] As a preferred embodiment of the waste suction head recycling device of the present invention, the first guide groove, the second guide groove, the third guide groove and the fourth guide groove are shallow grooves, the fifth guide groove is a deep groove, and a plurality of the transition slopes are respectively arranged at the connection between the fifth guide groove and the first guide groove, the second guide groove and the fourth guide groove. When the slide rod is slidably engaged in the deep groove, the gripper remains in an open state.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In this invention, when the slide moves to open the collection box, a gap exists between the slide and the inclined plate. The waste pipette tip detaches from the pipette and slides into the conical hole along the track of the inclined plate. The aerosol particles generated by the impact of falling are prevented from overflowing outward under the negative pressure inside the collection box, thus effectively preventing the aerosol from spreading outward, avoiding cross-contamination of experimental samples, and ensuring the accuracy of test results. When the slide moves to close the collection box, a sealed isolation is formed between the bottom of the slide and the inclined plate. The fan suction ensures that the gas above the slide can only pass through the middle of the waste pipette tip in the conical hole, thereby blowing the residual liquid in the waste pipette tip downward and achieving solid-liquid separation, reducing subsequent classification and processing steps, and improving work efficiency.

[0017] When the slide bar moves downward along the first guide groove, the transition slope extends from the deep groove to the shallow groove, gradually squeezing the slide bar so that the grippers of the clamping mechanism clamp the two sides of the suction head and finally apply downward pressure, so that the lower end of the suction head forms a seal with the inner wall of the conical hole, thereby allowing the residual liquid in the suction head to be smoothly blown downward when the fan is suctioned, improving the reliability and thoroughness of solid-liquid separation.

[0018] In this invention, the rotating shaft causes the telescopic rod to move along the guide groove, and under the action of the third spring, the telescopic rod and the slide rod smoothly enter the second guide groove along the first guide groove. When the slide rod rises in the second guide groove, it passes through the transition slope in the second guide groove, gradually squeezing the slide rod so that the gripper of the clamping mechanism clamps the two sides of the suction head. As the slide rod continues to move along the second guide groove, it eventually pulls the suction head out of the conical hole. Then, the slide rod moves horizontally along the third guide groove, moving the suction head held by the clamping mechanism to above the suction head collection part. Then, it slides down along the fourth guide groove. When it passes through the transition slope in the fourth guide groove, the gripper automatically releases the suction head, allowing it to fall into the suction head collection part. No manual intervention is required, which improves the degree of automation and efficiency.

[0019] As the slide bar moves horizontally along the third guide groove, the clamping mechanism moves the slide and the top cover, opening the collection box at the top of the inclined plate and allowing the next set of suction heads to fall smoothly into the collection box. Then, as the slide bar returns along the fifth guide groove, the clamping mechanism moves the slide horizontally to form a seal between the bottom of the slide and the inclined plate. At the same time, the grippers move to the sides of the corresponding suction head. As the slide bar moves downward along the first guide groove, the lower end of the next set of suction heads forms a seal with the inner wall of the conical hole, realizing the solid-liquid separation process of the next set of suction heads. The whole process is continuous and highly efficient.

[0020] When the slide rod moves along the shallow section of the guide groove, the slide rod is squeezed by the guide groove wall, which pushes the push rod to compress the first spring. The guide inclined surface on the push rod pushes the slider to slide. The slider drives the gripper through the connecting rod to overcome the elastic force of the second spring and clamp. When the slide rod moves to the deep section of the guide groove, the squeezing force of the guide groove wall on the slide rod is released, and the first and second springs reset and drive the gripper to open. Thus, the automatic control of the gripper is achieved through a purely mechanical structure, without the need for additional control components, reducing manufacturing costs and improving the reliability of operation.

[0021] When the slide moves to close the collection box with the top cover, the through holes on the slide connect with the openings on the top cover, forming a directional airflow channel when the fan draws in air. This guides the aerosol to the filter inside the air guide hood for treatment, thereby preventing the aerosol from accumulating in the collection box or escaping in the reverse direction. It also prevents aerosol particles from diffusing back into the chemiluminescence immunoassay analyzer and contaminating the reaction reagents, ensuring the reliability of the detection results of the fully automated chemiluminescence immunoassay analyzer.

Detailed Implementation

[0035] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention. The invention is by no means limited to any specific configurations and algorithms presented below, but covers any modifications, substitutions, and improvements to elements, components, and algorithms without departing from the spirit of the invention. Well-known structures and techniques are not shown in the drawings and the following description in order to avoid unnecessarily obscuring the invention.

[0036] Example 1, referring to Figures 1-12 As a first embodiment of the present invention, a waste pipette tip recycling device is provided. This waste pipette tip recycling device includes a recycling component 2 disposed within a chemiluminescence immunoassay analyzer 1. The recycling component 2 includes: The collection box 21 has a partition 211 fixed inside it; An inclined plate 25 is fixedly installed on one side of the collection box 21. The inclined plate 25 is provided with multiple slides 251. A conical hole 252 is provided at the bottom end of the slides 251 on the inclined plate 25 to make the suction head change from an inclined state to a vertical state. The slide 23 is horizontally slidably connected to the collection box 21. A top cover 22 for opening or closing the collection box 21 is fixedly installed on the top of the slide 23. When the slide 23 moves to close the top cover 22, a sealed isolation is formed between the bottom of the slide 23 and the inclined plate 25. The clamping mechanism is vertically slidably connected to the slide 23 and is used to clamp the suction head. The clamping mechanism includes a slide rod 261 for driving. The guide slot seat 27 is fixedly installed on one side of the collection box 21. The guide slot seat 27 is provided with a P-shaped guide slot. The slide rod 261 is slidably engaged in the guide slot. The guide slot is provided with multiple transition slopes 276. When the slide rod 261 passes through the transition slopes 276, the clamping mechanism performs clamping or releasing actions. A rotating shaft 28 is rotatably mounted on a guide groove seat 27. A telescopic rod is provided on the rotating shaft 28, and one end of the telescopic rod is sleeved on the outside of the slide rod 261. The air guide hood 24 is fixed to one side of the collection box 21, and the air guide hood 24 is equipped with a fan 241.

[0037] The partition 211 divides the collection box 21 into a waste liquid collection section 212 and a suction head collection section 213. The waste liquid collection section 212 is located directly below the conical hole 252.

[0038] The chemiluminescence immunoassay analyzer 1 is also equipped with a pipette tip holder, a sampling holder, and a test rack, as well as a pipetting module that is horizontally slidably set above the pipette tip holder, sampling holder, test rack, and recovery assembly 2. The pipetting device of the pipetting module can also move up and down to pick up and put down pipette tips or to aspirate and discharge reagents. The pipetting device is also equipped with a pusher for retracting pipette tips, so that multiple waste pipette tips at the bottom of the pipetting device can be retracted at the same time.

[0039] The telescopic rod includes a cylinder 281 fixed to the outside of the rotating shaft 28 and a rod 282 with one end sliding into the cylinder 281. A third spring 283 is fixedly connected between the inside of the rod 282 and the bottom surface of the cylinder 281. A motor is fixed to one side of the collection box 21, and the output shaft of the motor is coaxially fixed with the rotating shaft 28.

[0040] A baffle 253 is fixed to the bottom of the inclined plate 25 on the side away from the slide 251. When the slide 23 moves to close the top cover 22, the bottom of the slide 23 and the top of the baffle 253 form a seal. The baffle 253 serves two purposes: firstly, to achieve a sealing fit between the slide 23 and the inclined plate 25, ensuring that the airflow can only pass through the inside of the suction head when the fan 241 is drawing, ensuring that residual liquid is effectively blown off; secondly, to prevent the waste suction head from shifting outward from the inclined plate 25 during the sliding process and escaping from the non-recycling area, preventing the suction head from falling outside the collection box 21 or getting stuck in the gap of the mechanism, ensuring that the waste suction head can only fall into the conical hole 252 along the slide 251 and enter the designated recycling area, improving the recycling reliability and the stability of the mechanism operation.

[0041] A filter 242 is fixed at the inlet of the air guide hood 24. To simultaneously intercept bioaerosols and volatile chemical pollutants, the filter 242 at the inlet of the air guide hood 24 employs a combined multi-stage filtration structure. A HEPA high-efficiency air filter is the core filter element, using H14 grade filter media. This effectively traps most bioaerosols, pathogenic microorganisms, and sample droplets, preventing their diffusion with the airflow. Furthermore, an activated carbon fiber adsorption layer can be added at the front or rear of the HEPA filter to adsorb volatile organic compounds, chemical odors, and corrosive gases generated during the experiment, further enhancing the biosafety and environmental protection performance of the device.

[0042] The length of the top cover 22 is less than the length of the top opening of the collection box 21. The slide 23 has a through hole 231. When the top cover 22 closes the top of the inclined plate 25, a gap is formed between the other end of the top cover 22 and the collection box 21 to connect to the outside, which is used to form an airflow channel when the fan 241 draws.

[0043] The guide grooves on the guide groove seat 27 include a first guide groove 271, a second guide groove 272, a third guide groove 273, a fourth guide groove 274 and a fifth guide groove 275 connected in sequence. The end of the fifth guide groove 275 is connected to the connection between the first guide groove 271 and the second guide groove 272.

[0044] The first guide groove 271, the second guide groove 272, the third guide groove 273 and the fourth guide groove 274 are shallow grooves, the fifth guide groove 275 is a deep groove, and multiple transition slopes 276 are respectively set at the connection between the fifth guide groove 275 and the first guide groove 271, the second guide groove 272 and the fourth guide groove 274.

[0045] During use, the pipette of the chemiluminescence immunoassay analyzer 1 moves down above the tip holder, so that a tip is connected to the bottom of each channel of the pipette. The tip and the bottom of the channel are sealed by an interference fit. Then the pipette moves to the sampling rack to pick up the reagent and adds it to the reaction container on the experimental rack. Finally, the pipette is moved above the recovery assembly 2, and the used tip is removed into the recovery assembly 2 by the pusher, thus realizing a fully automated chemiluminescence immunoassay process.

[0046] When waste suction heads need to be recycled, the motor drives the rotating shaft 28 to rotate the cylinder 281 of the telescopic rod, and the cylinder 281 drives the round rod 282 to rotate. One end of the round rod 282 is sleeved on the outside of the slide rod 261, thereby driving the slide rod 261 to move along the guide groove on the guide groove seat 27. Initially, the slide rod 261 is located within the first guide groove 271. As the rotating shaft 28 rotates, the slide rod 261 moves upward along the first guide groove 271. Under the elastic force of the third spring 283, the round rod 282 causes the slide rod to always abut against the side of the first guide groove 271 away from the fifth guide groove 275, allowing the slide rod 261 to enter the second guide groove 272 from the first guide groove 271, and then continue to move upward along the second guide groove 272. During this process, the clamping mechanism only moves upward on the slide 23. After the slide rod 261 enters the third guide groove 273 from the second guide groove 272, the slide rod 261 moves horizontally along the third guide groove 273. At the same time, the clamping mechanism drives the slide 23 and the top cover 22 to move, causing the inclined... The collection box 21 at the top of plate 25 opens, and the pipette moves down to allow the used pipette tip to enter the collection box 21. After the waste pipette tip is removed from the pipette by the pusher, it falls into the slide 251 on the inclined plate 25 and slides down to the conical hole 252 at the bottom. The conical hole 252 changes the pipette tip from an inclined state to a vertical state. During this process, there is a gap between the slide 23 and the inclined plate 25. The fan 241 creates a negative pressure in the collection box 21, which effectively suppresses the aerosol particles generated by the falling impact and prevents them from overflowing outward. This effectively prevents the aerosol from spreading outward, avoids cross-contamination of experimental samples, and ensures the accuracy of the test results. The slide bar 261 continues to move along the fourth guide groove 274 and the fifth guide groove 275. Since the fifth guide groove 275 is a deep groove, the clamping mechanism is in an open state. When the slide bar 261 moves to the end of the fifth guide groove 275, the clamping mechanism is located outside the corresponding suction head. At the same time, the top cover 22 closes the opening of the collection box 21 above the inclined plate 25. Meanwhile, the bottom of the slide frame 23 and the top of the baffle 253 on the inclined plate 25 form a surface seal. Then, the motor rotates in the opposite direction by a small angle, causing the round rod 282 to drive the slide bar. 261 slides downward along the first guide groove 271. Since the first guide groove 271 is a shallow groove, the transition slope inside the first guide groove 271 causes the slide rod 261 to be squeezed by the guide groove wall, so that the clamping mechanism clamps the two sides of the suction head and finally applies downward pressure, so that the lower end of the suction head forms a seal with the inner wall of the conical hole 252. The gas above the slide 23 can only pass through the middle of the waste suction head inside the conical hole 252, blowing the residual liquid inside the suction head downward and falling into the waste liquid collection part 212 directly below, thereby improving the efficiency, reliability and thoroughness of solid-liquid separation.

[0047] Then, when the next set of suction heads needs to be retrieved, the rotating shaft 28 rotates, causing the telescopic rod to move the slide rod 261 along the guide groove. Under the action of the third spring 283, the telescopic rod moves the slide rod 261 smoothly into the second guide groove 272 along the first guide groove 271. When the slide rod 261 rises in the second guide groove 272, it passes through the transition slope 276 in the second guide groove 272, gradually squeezing the slide rod 261 so that the clamping mechanism clamps the two sides of the suction head. As the slide rod 261 continues to move along the second guide groove 272, it eventually drives the suction head to move. The suction head is pulled out of the conical hole 252, and then the slide rod 261 moves horizontally along the third guide groove 273, so that the suction head held by the clamping mechanism moves to the top of the suction head collection part 213, and then slides down along the fourth guide groove 274. When passing through the transition slope 276 in the fourth guide groove 274, the clamping mechanism automatically releases the suction head and lets it fall into the suction head collection part 213, realizing the recovery of the previous set of suction heads. At the same time, there are no suction heads blocking the conical hole 252. No manual intervention is required, which improves the degree of automation and efficiency.

[0048] During the above process, as the slide bar 261 moves horizontally along the third guide groove 273, the clamping mechanism drives the slide 23 and the top cover 22 to move, opening the collection box 21 at the top of the inclined plate 25, allowing the next set of suction heads to fall smoothly into the collection box 21. Subsequently, as the slide bar 261 returns along the fifth guide groove 275, the clamping mechanism drives the slide 23 to move horizontally, forming a sealed isolation between the bottom of the slide 23 and the inclined plate 25. The clamping mechanism moves to both sides of the corresponding suction head, and as the slide bar 261 moves downward along the first guide groove 271, the lower end of the next set of suction heads forms a seal with the inner wall of the conical hole 252, realizing the solid-liquid separation process of the next set of suction heads. The entire process is continuous and highly efficient. This cycle repeats continuously to achieve continuous automatic recycling.

[0049] When the slide 23 moves to close the opening of the collection box 21 above the inclined plate 25, the length of the top cover 22 is less than the length of the opening of the collection box 21. The other side of the top cover 22 allows the inside and outside of the collection box 21 to communicate, and the through hole 231 on the slide 23 communicates with the outside. When the fan 241 draws in, a directional airflow channel is formed, which guides the aerosol to the filter 242 in the air guide hood 24 for treatment. This prevents the aerosol from accumulating in the collection box 21 or escaping in the reverse direction, and prevents the aerosol particles from diffusing back into the chemiluminescence immunoassay analyzer 1 and contaminating the reaction reagents, thus ensuring the reliability of the detection results of the fully automated chemiluminescence immunoassay analyzer.

[0050] In summary, when the slide 23 moves to open the collection box 21 with the top cover 22, there is a gap between the slide 23 and the inclined plate 25. The waste pipette tip falls off the pipette and slides into the conical hole 252 along the slide 251 of the inclined plate 25. The aerosol particles generated by the falling impact are effectively suppressed by the negative pressure in the collection box 21, preventing them from overflowing outward. This effectively prevents the aerosol from spreading outward, avoids cross-contamination of experimental samples, and ensures the accuracy of the test results. When the slide 23 moves to close the collection box 21 with the top cover 22, a sealed isolation is formed between the bottom of the slide 23 and the inclined plate 25. The fan 241 draws in gas so that the gas above the slide 23 can only pass through the middle of the waste pipette tip in the conical hole 252, thereby blowing the residual liquid in the waste pipette tip downward, realizing solid-liquid separation, reducing subsequent classification and processing procedures, and improving work efficiency.

[0051] Example 2, refer to Figures 5-9 This is the second embodiment of the present invention, which differs from the first embodiment in that: The clamping mechanism also includes a clamping seat 26, in which multiple sets of grippers 262 slide symmetrically. Each set of grippers 262 is connected to a second spring 266. The clamping seat 26 is provided with multiple sliding grooves 265, in which sliders 268 are slidably connected. Each slider 268 is rotatably connected to two corresponding grippers 262 on both sides by connecting rods 267.

[0052] A push rod 264 is slidably connected inside the clamping seat 26. A slide rod 261 is fixed to one end of the push rod 264. A first spring 263 is fixedly connected between the other end of the push rod 264 and the inside of the clamping seat 26. The push rod 264 is provided with multiple guide slopes 269. The ends of multiple sliders 268 are provided with chamfers that slide in cooperation with the guide slopes 269.

[0053] When the slide bar 261 slides into the deep groove, the gripper 262 remains open.

[0054] During use, when the slide rod 261 moves along the first guide groove 271, the second guide groove 272, the third guide groove 273, and the fourth guide groove 274, the shallow groove causes the slide rod 261 to be squeezed by the guide groove wall, pushing the push rod 264 to compress the first spring 263. The guide inclined surface 269 on the push rod 264 pushes the slider 268 to slide along the slide groove 265. The slider 268 drives the gripper 262 to overcome the elastic force of the second spring 266 and clamp through the connecting rod 267. When the slide rod 261 moves to the fifth guide groove 275, the squeezing force of the guide groove wall of the deep groove on the slide rod 261 is released, the first spring 263 and the second spring 266 are reset, the push rod 264 returns to its position, the pushing force of the guide inclined surface 269 on the slider 268 disappears, and the slider 268 drives the gripper 262 to open through the connecting rod 267 under the action of the second spring 266.

[0055] Through the transmission of the above-mentioned purely mechanical structure, the automatic clamping and opening of the gripper 262 is realized when the slide bar 261 is in different guide groove sections. No additional sensors or controllers are required. The structure is compact and the operation is reliable.

[0056] The remaining structure is the same as that in Example 1.
