Abstract
Description
Technical Field
[0001] This invention relates to the field of data acquisition devices, and more particularly to a data acquisition device. Background Technology
[0002] Cell-free circulating DNA refers to DNA fragments that originate from apoptosis or necrosis and are free outside the cell. They are widely present in human serum, plasma, cerebrospinal fluid, urine, or saliva. Currently, cell-free DNA has been used as a new biomarker in fields such as tumor detection, post-organ transplant rejection, and infection detection.
[0003] Using cell-free DNA in urine for basic molecular biology research and clinical diagnosis has many unique advantages: urine collection is non-invasive and non-traumatic, and extracting cell-free DNA from urine is simpler than extracting it from blood. Cell-free DNA in urine mainly comes from the shedding of epithelial cells from organs in the urinary system, as well as a small amount of leukocyte degradation and pathogen fragments from infection. When the human urinary system is diseased, the content of cell-free DNA in urine also changes accordingly.
[0004] After a batch of urine samples is processed by a centrifuge, the supernatant from each urine sample needs to be collected (at this time, the supernatant of the urine sample contains a large amount of cell-free DNA). Usually, a pipette is used to extract a quantitative amount of supernatant from the urine sample, and then the extracted supernatant is injected into a collection tube. Then, a printed label is manually affixed to the surface of the collection tube to complete the collection of cell-free DNA from a single urine sample. When performing batch collection, manually affixing labels to the surface of the collection tube is quite troublesome. Summary of the Invention
[0005] This invention provides a collection device that can solve the problem in the prior art: after the extracted supernatant is injected into the collection tube, a printed label is usually manually affixed to the surface of the collection tube.

[0012] As a further technical solution of the present invention, a fixed base is fixed on the upper end surface of the platform, a rotating column is rotatably provided on the upper end surface of the fixed base, an extension arm is fixed on one side of the rotating column, a lifting plate is provided below the extension arm, a clamping assembly is provided on the lower end surface of the lifting plate, and a lifting assembly for use with the lifting plate is provided on the extension arm.
[0013] As a further technical solution of the present invention, the clamping assembly includes two connecting plates fixed to the lower end face of the lifting plate. Each connecting plate has an electric push rod fixed to its lower end face. An arc-shaped clamping block is fixed to the end of the telescopic end of the electric push rod. An anti-slip layer is fixed on the inner wall of the arc-shaped clamping block. Two guide plates are symmetrically fixed on one side of the arc-shaped clamping block. Guide seats are fixed on both sides of the electric push rod. The guide plates movably pass through the guide seats. A connecting cylinder is fixed to the lower end face of the lifting plate. The lower end of the connecting cylinder is open. Two side through grooves that cooperate with the arc-shaped clamping block are symmetrically opened on the outer surface of the connecting cylinder.

[0014] As a further technical solution of the present invention, the adsorption unit includes a vacuum suction cup fixed to the top of the connecting cylinder, a suction hose is provided on the upper end face of the vacuum suction cup, a suction unit is fixed on the upper end face of the rotating column, and one end of the suction hose is connected to the suction unit.
[0015] As a further technical solution of the present invention, the lifting assembly includes a second electric push rod fixedly penetrating the extension arm. The end of the telescopic end of the second electric push rod is fixedly connected to the lifting plate. Two guide columns are symmetrically fixed on the upper end of the lifting plate, and the upper end of each guide column is movably penetrating the extension arm.
[0016] The beneficial effects of this invention are: 1. In use, the operator uses a pipette to extract the supernatant of the centrifuged urine into a sampling tube, then inserts the sampling tube into the placement slot. The drive mechanism then rotates the sampling tube located in the placement slot. During this process, the labeling mechanism works to label the sampling tube. Then, both the labeling mechanism and the drive mechanism stop working. At this time, the operator removes the labeled sampling tube from the placement slot, completing the collection of a single sample. There is no need to manually label the sampling tube, making it suitable for batch collection.
[0017] 2. In use, the sampling tube to be used can also be placed in the placement slot before collecting the supernatant from the urine. At this time, the extension arm rotates with the lifting plate to above the sampling tube. Then, under the action of the lifting assembly, the lifting plate moves down with the clamping assembly. The clamping assembly then clamps and fixes the cap of the sampling tube. Then, the friction roller drives the tube body to rotate forward. During this process, the lifting assembly drives the lifting plate and clamping assembly to slowly rise, thereby removing the cap from the tube body. During this process, the operator can use a pipette to complete the centrifugation of the urine. The supernatant of the liquid is extracted, and then the extension arm, along with the lifting plate and cap, rotates away from the placement rack. The operator then injects the liquid from the pipette into the tube located in the placement slot. The extension arm, along with the lifting plate and cap, rotates closer to the placement rack. Under the action of the lifting assembly, the lifting plate, along with the clamping assembly and cap, slowly moves downward. At this time, the friction roller drives the tube body of the sampling tube to rotate in the opposite direction, thereby cooperating with the clamping assembly to screw the cap onto the tube body. During this process, the labeling of the sampling tube is also completed. Then the extension arm rotates away from the sampling tube again, and the operator can take out the labeled sampling tube for convenient use.
[0018] 3. After the connecting sleeve is placed on the outer surface of the cap, the upper end of the cap abuts against the lower surface of the vacuum suction cup. At this time, the air extraction unit works, and with the air extraction hose, it adsorbs the cap onto the lower surface of the vacuum suction cup. When the cap is unscrewed from the tube, the telescopic end of the electric push rod retracts, thereby driving the arc-shaped clamping block and the anti-slip layer away from the surface of the cap. Since the inner wall of the cap is not supported by the tube at this time, the telescopic end of the electric push rod retracts to prevent the cap from deforming in this state, which would affect the subsequent placement of the cap onto the tube.

Detailed Implementation
[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0022] Reference Figures 1-14A collection device includes a pipette and a stage 101. A placement rack 102 is fixed to the upper end face of the stage 101. A placement notch 103 is formed on the upper end face of the placement rack 102. Multiple rotating wheels 104 are rotatably arranged on the inner wall of the placement notch 103. A labeling mechanism for use with the placement notch 103 is provided on the upper end face of the stage 101. A lateral notch 105 is formed on the side of the placement rack 102 away from the labeling mechanism. The lateral notch 105 extends into the placement notch 103. A drive mechanism for use with the placement notch 103 is provided on the stage 101.
[0023] The pipette is existing technology, and the labeling mechanism is electrically connected to the peripheral computer.
[0024] This application is designed for use with the sampling tube 600. When in use, the stage 101 is placed on the experimental workbench.
[0025] In use, the operator uses a pipette to extract the supernatant of centrifuged urine into a sampling tube 600, then inserts the sampling tube 600 into the placement slot 103. The drive mechanism then rotates the sampling tube 600 located in the placement slot 103. During this process, the labeling mechanism works to label the sampling tube 600. After that, both the labeling mechanism and the drive mechanism stop working. At this point, the operator removes the labeled sampling tube 600 from the placement slot 103, completing the collection of a single sample. There is no need to manually label the sampling tube 600, making it suitable for batch collection.
[0026] The labeling mechanism includes a base 200 fixed to the upper surface of a platform 101. A rotating disk 201 is rotatably mounted on the upper surface of the base 200. A positioning post 202 is fixed to the upper surface of the rotating disk 201. A winding paper tube 203 is detachably mounted on the positioning post 202. A label paper tape 204 with a label body is wound around the outer surface of the winding paper tube 203. A peeling plate 205 is fixed to the upper surface of the base 200. A rotating disk 206 is rotatably mounted on the upper surface of the base 200. The upper surface of the rotating disk 206 is fixed... There is a positioning post 207, on which a waste paper tube 208 is detachably mounted. One end of the label paper tape 204 passes around the peeling plate 205 and is fixedly connected to the waste paper tube 208. Multiple guide rollers 209 are rotatably mounted on the upper end face of the base 200. An abutment guide roller 210 is rotatably mounted on the upper end face of the base 200. A printing assembly is mounted on the base 200. The printing assembly is existing technology. A cavity is provided inside the base 200. A drive unit 1 that works with the rotating disk 201 and the rotating disk 206 is provided inside the cavity.
[0027] The drive unit is existing technology, driving the rotation of rotating disk 201 and rotating disk 206, which is a conventional technical means in this field.
[0028] The positioning post 202's limiting and fixing of the winding paper tube 203, and the positioning post 207's limiting and fixing of the waste paper tube 208, are both existing technologies.
[0029] When the labeling mechanism is working, the rotating disk 206 drives the positioning column 207 and the waste paper tube 208 to rotate, thereby driving the label paper strip 204 with the label body to move. When the label body follows the label paper strip 204 past the printing component, the printing component prints the corresponding information on the surface of the label body. Then the label body continues to follow the label paper strip 204. When it passes the end of the peeling plate 205, the label body will separate from the label paper strip 204. With the cooperation of the abutting guide roller 210, a single label paper strip 204 is pasted onto the sampling tube 600 which is in a rotating state (slow speed).
[0030] The printing assembly includes a printer 211 disposed on the upper surface of the base 200. The printer 211 is prior art. A rotating disk 212 is rotatably disposed on the upper surface of the base 200. A positioning post 213 is fixed on the upper surface of the rotating disk 212. A winding paper tube 214 is detachably sleeved on the positioning post 213. A carbon ribbon 215 is wound around the outer surface of the winding paper tube 214. A rotating disk 216 is rotatably disposed on the upper surface of the base 200. A positioning post 217 is fixed on the upper surface of the rotating disk 216. A waste paper tube 218 is detachably sleeved on the positioning post 217. One end of the carbon ribbon 215 passes around the printer 211 and is fixedly connected to the waste paper tube 218. A plurality of guide rollers 219 are disposed on the base 200 to cooperate with the carbon ribbon 215. A drive unit 2 is disposed in the cavity to cooperate with the rotating disk 212 and the rotating disk 216.
[0031] When the printing assembly is working, the rotating disk 216 drives the positioning column 217 and the waste paper tube 218 to rotate, thereby driving the ribbon 215 to rotate. The ribbon 215 adheres to the label body and passes through the printer 211, so that the printer 211 can print the required information on the surface of the label body. This part of the structure is all existing technology.
[0032] The driving mechanism includes a sliding groove 300 formed on the upper surface of the stage 101. A sliding seat 301 is slidably disposed in the sliding groove 300. Two support blocks 302 are fixed on the upper surface of the sliding seat 301. The same U-shaped frame 303 is fixed on the upper surface of the two support blocks 302. A friction roller 304 is rotatably disposed in the U-shaped frame 303. A driving unit three that works with the friction roller 304 is disposed on the U-shaped frame 303. A driving unit four that works with the sliding seat 301 is disposed in the sliding groove 300.
[0033] The dimensions of the lateral notch 105 are matched with those of the U-shaped frame 303 and the friction roller 304.
[0034] In the initial state, the U-shaped frame 303 and the friction roller 304 are positioned away from the placement notch 103 to avoid affecting the placement of the sampling tube 600. After the sampling tube 600 is placed into the placement notch 103, the drive unit drives the sliding seat 301, support block 302, U-shaped frame 303 and friction roller 304 to move towards the sampling tube 600 until the friction roller 304 is tightly attached to the outer surface of the sampling tube 600. When the drive unit drives the friction roller 304 to rotate, it drives the sampling tube 600 to rotate together to cooperate in the labeling operation.
[0035] The third drive unit includes a drive roller 305 rotatably mounted on the inner wall of the U-shaped frame 303. The drive roller 305 abuts against the surface of the friction roller 304. A working motor 306 for use with the drive roller 305 is fixed on the lower end face of the U-shaped frame 303.
[0036] When the working motor 306 causes the drive roller 305 to rotate, the drive roller 305 drives the friction roller 304 to rotate under the action of friction.
[0037] In other embodiments, other driving methods can also be used to drive the friction roller 304 to rotate, and driving the friction roller 304 to rotate is a conventional technical means in the art.
[0038] The drive unit four includes an electromagnet 307 fixed on the inner wall of the sliding groove 300, a magnet layer 308 fixed on one side of the sliding seat 301, and multiple guide rods fixed on one side of the sliding groove 300. The end of each guide rod extends movably into the sliding seat 301. Multiple springs 310 are fixed between the sliding seat 301 and the sliding groove 300. The springs 310 are movably sleeved on the outer surface of the guide rods. A controller that works with the electromagnet 307 is provided in the cavity.
[0039] In the initial state, the electromagnet 307 is de-energized. When the sampling tube 600 is placed into the placement slot 103, the electromagnet 307 is energized, thereby attracting the magnet layer 308 and driving the sliding seat 301 to move towards the electromagnet 307. During this process, the spring 310 is stretched and deformed, storing elastic potential energy. When the sampling tube 600 is labeled, the electromagnet 307 is de-energized. At this time, under the action of the elastic potential energy of the spring 310, the sliding seat 301 is moved away from the electromagnet 307, causing the sliding seat 301, support block 302, U-shaped frame 303 and friction roller 304 to move away from the sampling tube 600, so as to avoid the friction roller 304 affecting the removal of the sampling tube 600.
[0040] The sampling tube 600 is a rigid tube. The friction roller 304 will not damage the sampling tube 600 during operation. The sampling tube 600 includes a tube body 601 and a screw cap 602. In the initial state, the screw cap 602 is screwed onto the upper end of the tube body 601.
[0041] A fixed base 400 is fixed to the upper end face of the stage 101. A rotating column is rotatably mounted on the upper end face of the fixed base 400. An extension arm 401 is fixed to one side of the rotating column. A lifting plate 402 is mounted below the extension arm 401. A clamping assembly is mounted on the lower end face of the lifting plate 402. A lifting assembly for use with the lifting plate 402 is mounted on the extension arm 401. A drive unit five for use with the rotating column is mounted on the fixed base 400. The drive unit five is existing technology. The rotation of the rotating column is a conventional technical means in this field.
[0042] In this application, the sampling tube 600 to be used can be placed in the placement slot 103 first. At this time, the sampling tube 600 has not yet collected the supernatant from the urine. At this time, the extension arm 401 rotates with the lifting plate 402 to the top of the sampling tube 600. Then, under the action of the lifting component, the lifting plate 402 moves down with the clamping component. Then, the clamping component clamps and fixes the cap 602 of the sampling tube 600. Then, the friction roller 304 drives the tube body 601 of the sampling tube 600 to rotate in the forward direction. During this process, the lifting component drives the lifting plate 402 and the clamping component to slowly rise, thereby removing the cap 602 from the tube body 601. During this process, the operator can use a pipette to extract the supernatant of the urine after centrifugation. Then, the extension arm 401, along with the lifting plate 402 and the cap 602, rotates away from the placement rack 102. The operator then injects the liquid from the pipette into the tube 601 located in the placement slot 103. The extension arm 401, along with the lifting plate 402 and the cap 602, rotates closer to the placement rack 102. Under the action of the lifting assembly, the lifting plate 402, along with the clamping assembly and the cap 602, slowly moves downward. At this time, the friction roller 304 drives the tube 601 of the sampling tube 600 to rotate in the opposite direction, thereby cooperating with the clamping assembly to screw the cap 602 onto the tube 601. During this process, the labeling of the sampling tube 600 is also completed. Then, the extension arm 401 rotates away from the sampling tube 600 again, and the operator can take out the labeled sampling tube 600 for convenient use.
[0043] To ensure a tight seal, staff can tighten the cap 602 of the removed sampling tube 600 again. During this process, since the cap 602 has already been initially tightened, it will not rotate more than once.
[0044] The clamping assembly includes two connecting plates 403 fixed to the lower end face of the lifting plate 402. Each connecting plate 403 has an electric push rod 404 fixed to its lower end face. An arc-shaped clamping block 405 is fixed to the end of the telescopic end of the electric push rod 404. An anti-slip layer 406 is fixed to the inner wall of the arc-shaped clamping block 405. Two guide plates 407 are symmetrically fixed to one side of the arc-shaped clamping block 405. Guide seats 408 are fixed to both sides of the electric push rod 404. The guide plates 407 move through the guide seats 408. A connecting cylinder 409 is fixed to the lower end face of the lifting plate 402. The lower end of the connecting cylinder 409 is open. Two side through grooves 410 are symmetrically opened on the outer surface of the connecting cylinder 409 to cooperate with the arc-shaped clamping block 405. An adsorption unit is provided inside the connecting cylinder 409.
[0045] In use, the lifting plate 402 moves down with the connecting cylinder 409 until the connecting cylinder 409 is fitted onto the outer surface of the screw cap 602. Then, the telescopic ends of the two electric push rods 404 extend, pushing the arc-shaped clamping block 405 and the anti-slip layer 406 close to the outer surface of the screw cap 602 until the two anti-slip layers 406 abut against the outer surface of the screw cap 602, clamping the screw cap 602, thereby cooperating with the rotating tube 601 to unscrew the screw cap 602 from the tube 601.
[0046] Similarly, the cap 602 can be screwed onto the tube body 601.
[0047] The adsorption unit includes a vacuum suction cup 411 fixed inside the top of the connecting cylinder 409. The upper end face of the vacuum suction cup 411 is connected to a suction hose 412. The upper end face of the rotating column is fixed to a suction unit 413. One end of the suction hose 412 is connected to the suction unit 413. The suction unit 413 is existing technology.
[0048] After the connecting cylinder 409 is fitted onto the outer surface of the cap 602, the upper end of the cap 602 abuts against the lower surface of the vacuum suction cup 411. At this time, the vacuum pumping unit 413 works, and together with the vacuum pumping hose 412, it adsorbs the cap 602 onto the lower surface of the vacuum suction cup 411. When the cap 602 is unscrewed from the tube 601, the telescopic end of the electric push rod 404 retracts, thereby driving the arc-shaped clamping block 405 and the anti-slip layer 406 away from the surface of the cap 602. Since the inner wall of the cap 602 is not supported by the tube 601 at this time, the telescopic end of the electric push rod 404 is retracted to prevent the cap 602 from deforming in this state, thereby affecting the subsequent fitting of the cap 602 onto the tube 601.
[0049] When it is necessary to retighten the cap 602 onto the tube body 601, the lifting plate 402 moves downward with the connecting cylinder 409 and the cap 602 until the cap 602 is initially fitted onto the upper end of the tube body 601. Then, the telescopic end of the electric push rod 404 extends again, pushing the arc-shaped clamping block 405 and the anti-slip layer 406 close to the outer surface of the cap 602 to clamp the cap 602 and cooperate to tighten the cap 602.
[0050] The lifting assembly includes an electric push rod 500 fixedly passing through the extension arm 401. The end of the telescopic end of the electric push rod 500 is fixedly connected to the lifting plate 402. Two guide posts 501 are symmetrically fixed on the upper end of the lifting plate 402. The upper end of each guide post 501 is movable through the extension arm 401.
[0051] When the telescopic end of the electric actuator 2 500 extends, it will drive the lifting plate 402 to move downward; when the telescopic end of the electric actuator 2 500 retracts, it will drive the lifting plate 402 to move upward.
[0052] In use, the operator uses a pipette to extract the supernatant of centrifuged urine into a sampling tube 600, then inserts the sampling tube 600 into the placement groove 103. The drive mechanism then drives the sampling tube 600 located in the placement groove 103 to rotate. During this process, the labeling mechanism works to label the sampling tube 600. Then, both the labeling mechanism and the drive mechanism stop working. At this time, the operator removes the labeled sampling tube 600 from the placement groove 103, completing the collection of a single sample. There is no need to manually label the sampling tube 600, making it suitable for batch collection. In use, the sampling tube 600 to be used can be placed in the placement slot 103 first. At this time, the sampling tube 600 has not yet collected the supernatant from the urine. At this time, the extension arm 401 rotates with the lifting plate 402 to above the sampling tube 600. Then, under the action of the lifting component, the lifting plate 402 moves down with the clamping component. Then, the clamping component clamps and fixes the cap 602 of the sampling tube 600. Then, the friction roller 304 drives the tube body 601 of the sampling tube 600 to rotate in the forward direction. During this process, the lifting component drives the lifting plate 402 and the clamping component to slowly rise, thereby removing the cap 602 from the tube body 601. During this process, the operator can use a pipette to extract the supernatant of the urine after centrifugation. Then, the extension arm 401, along with the lifting plate 402 and the cap 602, rotates away from the placement rack 102. The operator then injects the liquid from the pipette into the tube 601 located in the placement slot 103. The extension arm 401, along with the lifting plate 402 and the cap 602, rotates closer to the placement rack 102. Under the action of the lifting assembly, the lifting plate 402, along with the clamping assembly and the cap 602, slowly moves downward. At this time, the friction roller 304 drives the tube 601 of the sampling tube 600 to rotate in the opposite direction, thereby cooperating with the clamping assembly to screw the cap 602 onto the tube 601. During this process, the labeling of the sampling tube 600 is also completed. Then, the extension arm 401 rotates away from the sampling tube 600 again, and the operator can take out the labeled sampling tube 600 for convenient use.
