Abstract
Description
Technical Field
[0001] The present invention relates to a multifunctional automatic post-processing device based on biological fluid sample filtration, wherein the biological fluid specifically includes urine, saliva, human milk, blood and other liquids. Background Art
[0002] Hospitals perform a large number of biofluid tests each year, but these samples cannot be stored long-term under normal conditions, leading to the disposal of a vast amount of valuable samples. Currently, biofluid storage is costly, technically challenging, and requires significant space, making it difficult to establish a biofluid sample library. A method for storing biofluid samples and establishing a long-term, effective biofluid sample library would allow for timely extraction and analysis. This would be crucial for disease screening and prevention, accurate diagnosis and prognosis of individual illnesses, and improving public health. Currently, more researchers are exploring the use of manual filtration of biofluids through a membrane filter to retain proteins on the membrane. The membrane is then dried to create a dry membrane biofluid sample, which is then vacuum-sealed for long-term, reliable storage for subsequent analysis. However, this manual filtration method, using a fixed membrane device, can lead to cross-contamination when removing the adsorption filter membrane. Furthermore, large sample volumes can lead to confusion and asymmetry between sample information and actual recorded information. Summary of the Invention

[0025] The storage component 300 is disposed in the sliding component 100 . The sliding component 100 is also slidably connected to the functional component 200 . The functional component 200 adjusts its relative position with the storage component 300 by sliding.
[0026] like Figure 2 As shown, the sliding assembly 100 includes a bottom plate 101, a vertical plate 104, a screw motor 105, a top plate 106, a linear guide slider component 107 and a sliding platform 108;
[0027] The bottom plate 101 is fixedly connected to the top plate 106 through a pair of vertical plates 104, the vertical plates 104 are provided with the screw motor 105, the top plate 106 is provided with the linear guide slider component 107, the linear guide slider component 107 is slidably connected to the sliding platform 108, the screw motor 105 is transmission-connected to the sliding platform 108 through a screw nut, the screw motor 10 utilizes forward rotation or reverse rotation to move the sliding platform 108 horizontally, and the top plate 106 is provided with an image recognition camera 2;
[0028] A pair of butterfly bolts 102 are provided through the base plate 101. The base plate 101 can be quickly fixed or removed by rotating the butterfly bolts 102. A fulcrum step screw 103 is arranged on both sides of the base plate 101. The butterfly bolts 102 can be quickly removed manually. The sliding assembly can rotate along the fulcrum step screw 103 on one side as a rotating axis, and the fulcrum step screw 103 on the other side is used for positioning when rotating and resetting.
[0029] like Figure 3 As shown, the functional component 200 includes a container base 201, a vacuum suction cup 202, a pressure column 203, a guide rod cylinder 205 and an inkjet printer nozzle 207;
[0030] The collecting base plate 201 is fixedly connected to the sliding platform 108, and the guide rod cylinder 205 is fixed to the collecting base plate 201 through the cylinder mounting plate 204. The guide rod cylinder 205 is transmission-connected to the pressure column 203, and the bottom end of the pressure column 203 is embedded with the vacuum suction cup 202. The guide rod cylinder 205 can make the vacuum suction cup 202 and the pressure column 203 move axially together, and the vacuum suction cup 202 is flush with the end face of the pressure column 203. The vacuum suction cup 202 is connected to the vacuum pump, and the vacuum suction cup 202 uses vacuum to absorb the inkjet pad 305. The pressure column 203 can separate the diaphragm adapter 1 through the thrust of the guide rod cylinder 205. The separated filter screen holder is placed in the diaphragm collection tank 308. The inkjet printer nozzle 207 is fixed to the collecting base plate 201 through the nozzle fixing seat 206. By utilizing horizontal movement and receiving the coding instructions from the upstream controller, dynamic printing of sample diaphragm information is achieved.
[0031] like Figure 4 As shown, the storage assembly 300 includes a dual-chamber base 301, a feed cylinder 302 and a diaphragm collection tank 308;
[0032] The dual-cavity base 301 is fixedly supported by the side support plate 303 , and the dual-cavity base 301 is separated into a small cavity 311 and a large cavity 312 ;
[0033] The feeding cylinder 302 is arranged below the small cavity 311, and the inkjet paper pad 305 is arranged in the small cavity 311. The feeding cylinder 302 is in contact with the inkjet paper pad 305 through a sliding block 304 to provide floating support for the inkjet paper pad 305. A pluggable baffle 306 is arranged on the top of the inkjet paper pad 305. The top of the baffle 306 is in contact with a fixed baffle 307, and the fixed baffle 307 is fixed to the top surface of the double-cavity base 301;
[0034] The diaphragm collecting tank 308 is set in the large cavity 312. The inner wall of the diaphragm collecting tank 308 is in contact with the piston 309 through the O-ring 310, and generates appropriate friction. The separated filter holders in the diaphragm collecting tank 308 are pushed down step by step by the piston 309. The piston 309 is pushed down step by step by accumulating, so that the collected filter holders are regularly and neatly arranged in the diaphragm collecting tank 308.
[0035] Combine Figure 1 、 Figure 5 Explain the pad paper coding process. Figure 1 The initial state of the device is to start the screw motor 105 and rotate it in the forward direction, driving the sliding platform 108 to move toward the side close to the screw motor 105. When the sliding platform 108 finishes moving, the device is as follows: Figure 5 As shown, the inkjet printer nozzle 207 starts to perform the coding action at a preset point during the movement, and prints the content to be printed on the coding pad paper 305. The coding action is completed before the sliding platform 108 finishes moving. This coding process is a dynamic coding process.
[0036] Combine Figure 1 、 Figure 5 、 Figure 6 The paper picking process is described below. After the inkjet printing is completed, the status of the device is as follows: Figure 5 As shown, the screw motor 105 is started and rotated in the reverse direction, driving the sliding platform 108 to move away from the screw motor 105. When the sliding platform 108 finishes moving, the device is as shown in FIG. Figure 1 As shown, the guide rod cylinder 205 is started to move forward, driving the vacuum suction cup 202 to move downward and contact the inkjet printing pad 305, and at the same time, the vacuum pump is turned on to make the vacuum suction cup 202 have negative pressure and absorb the inkjet printing pad 305. At this time, the device is as shown in FIG. Figure 6 As shown, the guide rod cylinder 205 moves in the opposite direction, and the inkjet printing pad 305 is taken out by the vacuum suction cup 202, and the process of adsorption and paper removal is completed. Figure 1 shown.
[0037] Combine Figure 1 、 Figure 5 、 Figure 7 The separation of the membrane adapter 1 and the collection of the filter holder are described. After the adsorption and paper removal process is completed, the status of the device is as follows: Figure 1 As shown, the screw motor 105 is started and rotated in the forward direction, driving the sliding platform 108 to move toward the side close to the screw motor 105. When the movement is completed, the state of the device is as follows: Figure 5 As shown, the guide rod cylinder 205 is started to move forward, driving the vacuum suction cup 202 and the pressure column 203 to move simultaneously. The pressure column 203 uses the thrust of the guide rod cylinder 205 to separate the diaphragm adapter 1. The filter holder is placed on the piston 309 in the diaphragm collection tank 308. The piston 309 steps down and at the same time, the vacuum pump is turned off to separate the coding pad 305 from the vacuum suction cup 202, leaving the coding pad 305 above the sample diaphragm in the filter holder. At this time, the device is as shown in FIG. Figure 7 As shown, the guide cylinder 205 moves in the reverse direction, and the screw motor 105 rotates in the reverse direction, driving the sliding platform 108 to move away from the screw motor 105 and return to the initial state of the device. At this time, the device stops at the position shown in FIG. Figure 1 shown.
[0038] During the separation process of the diaphragm adapter 1, the device always maintains the coding pad paper 305 corresponding to the diaphragm in direct contact with the sample diaphragm, so that no part of the device is in direct contact with the sample diaphragm, fundamentally eliminating the risk of cross contamination. When the device is reset, the image recognition camera 2 is set on the top plate 106, which will verify and compare the content of the coding pad paper 305 remaining above the sample diaphragm after each separation, to ensure that the sample information content is complete, accurate and clear, and convenient for long-term storage.
[0039] Advantages of the present invention:
[0040] It solves the problems of low processing efficiency, easy sample loss, easy residue and cross contamination, the inability to achieve automatic synchronization of online interaction and transfer of information, and the problem of uncontrollable and substandard sample production indicators during the experiment.
[0041] The above description is only illustrative of the present invention and not restrictive. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, and all of them will fall within the scope of protection of the present invention.
