Description

Technical Field

[0001] The invention relates to the technical field of schistosome egg extraction, and more particularly to a disposable schistosome egg extraction filtering component. Background Art

[0002] Schistosomiasis is one of the three major infectious diseases in China. It is a parasitic disease that seriously endangers human health, hinders the social and economic development of the epidemic area, is contagious, endemic and has natural epidemic sources. It is listed by the WHO as a highly reproducible infectious disease. The gold standard for schistosomiasis diagnosis is still the traditional "nylon silk bag egg collection and hatching method" standard 20160301.

[0003] The traditional nylon silk egg hatching method is to stir the fecal residue filtered twice by the primary yarn net and fine yarn nylon silk, then place it in a conical flask, incubate it in relatively clean fecal water at a certain temperature, and use the "Schistosome Miracidia Dynamic Automatic Identification System" to observe the hatching of miracidia after 1-2 hours. Most of the operations are manual, with low efficiency and long time consumption, which greatly increases the cost of use. Therefore, automated intelligent system operations are needed to replace manual operations and improve efficiency. Summary of the invention

[0009] Furthermore, the flexible stirring mechanism includes a multifunctional stirring rod installed on the end cover, and the interior of the multifunctional stirring rod is respectively provided with a liquid input port and a plurality of liquid outlet nozzles, and the plurality of liquid outlet nozzles are all connected with the interior of the liquid input port. The intelligent schistosome egg extraction system gradually approaches the medium to be stirred by controlling the lifting height of the multifunctional stirring rod through the flexible stirring mechanism, so as not to penetrate into the stirring medium all at once, causing great stirring resistance and affecting the stability of the coarse screen filter box and the fine screen filter box. At the same time, the rotation direction of the multifunctional stirring rod can be controlled for adjustment. At the initial stage of stirring, when the viscosity and hardness of the medium are relatively high, the multifunctional stirring rod adopts forward rotation, that is, when stirring the medium, friction is adopted to gradually penetrate, and the multifunctional stirring rod is built-in with a liquid input port and a liquid outlet nozzle.

[0013] Furthermore, a sealing ring is fixedly connected to the outer end of the movable plate, and the outer end of the sealing ring contacts the inner wall of the external mounting frame. Through the setting of the sealing ring, the squeezed air in the external mounting frame can be fully blown into the air duct, reducing the possibility of upward leakage.

[0014] Furthermore, the plurality of release holes are located in the right area inside the filter membrane frame, and the inner walls of the plurality of release holes are fixedly connected with a sports spray bottle nozzle. Through the arrangement of the release holes and the sports spray bottle nozzle, the air blown into the air duct is ejected outward under the action of squeezing, blowing off the medium attached to the surface and reducing the possibility of blockage.

[0016] Furthermore, the fine screen filter is located at the lower side of the coarse screen filter, the mesh size of the coarse screen filter is larger than the mesh size of the fine screen filter, and both of the filtered liquid output ports can be externally connected to a negative pressure adsorption tube. By setting the coarse screen filter and the fine screen filter, layer-by-layer filtration is achieved, making the filtration more complete and comprehensive and enhancing the filtration effect.

The mixed liquid is filtered for the second time, and an external negative pressure adsorption tube is connected to increase the filtration speed through the adsorption force of negative pressure, so that the filtrate and the sample are quickly separated, and the filtrate is prompted to flow into the filtrate absorption chamber 702, and then discharged through the filtrate output port 705. Since the negative pressure chamber that can be generated is relatively large, even if most of the fine mesh filter 701 is blocked by substances, as long as it is not completely blocked, the negative pressure filtration will still work to enhance the filtration effect, and when the blocking valve 704 is pulled down to open, the separated sample is discharged into the container below through the sample output channel 703 with a certain slope, thereby realizing the filtration and extraction of the sample.

[0049] See also Figure 2 and Figure 5-6 The fine screen filter 701 is located at the lower side of the coarse screen filter 601, and the mesh size of the coarse screen filter 601 is larger than the mesh size of the fine screen filter 701. Both the two filtered liquid output ports 705 can be connected to a negative pressure adsorption tube. By setting the coarse screen filter 601 and the fine screen filter 701, layer-by-layer filtration is achieved, making the filtration more complete and comprehensive, and enhancing the filtration effect. The filtered liquid output port 705 can be connected to a negative pressure adsorption tube, which can use the adsorption force of negative pressure to accelerate the filtration speed and improve the filtration efficiency.

[0050] In the present invention, the intelligent schistosome egg extraction system controls the lifting height of the multifunctional stirring rod 501 to gradually approach the medium to be stirred, and in the initial stirring stage, when the viscosity and hardness of the medium are relatively high, the multifunctional stirring rod 501 is rotated in the forward direction to gradually penetrate into the medium by friction, and the aqueous solution is ejected through the liquid input port 502 and the liquid outlet port 503 as the multifunctional stirring rod 501 rotates, and the stirring medium is stirred while flushing water, so as to break up the medium as soon as possible and decompose and filter the contents, and then the coarse screen filter 601 performs the first filtration on the stirred and flushed medium, and the fine screen filter 701 performs the second filtration on it, and during the filtration process, when the coarse screen filter 601 and the fine screen filter 701 are partially blocked, the liquid increases too much, and enters the overflow pipe 602 through the double filtration of the filter membrane frame 605, and then is introduced into the overflow container 400, and the humidity sensor 6014 detects the inflow of liquid and feeds back to the drive motor 607, The cam 608 is driven to rotate, and the air inside the external mounting frame 606 is repeatedly squeezed to be blown into the air guide tube 6011, sprayed out, and the medium attached to the surface of the filter membrane frame 605 is blown off, reducing the possibility of blockage, so that the overflowed liquid can flow smoothly into the overflow container 400, avoiding blockage of the filter membrane frame 605. At the same time, the overflow detection float 603 floats upward with the flow of the liquid, and the position is gradually raised, driving the overflow detection float sensor rod 604 to send a signal, and the stirring and water spraying devices are controlled by the intelligent schistosome egg extraction system to stop working, avoiding affecting the internal stirring and filtering, and the filtrate output port 705 can be externally connected to a negative pressure adsorption tube to speed up the filtration speed, reduce blockage, and quickly separate the filtrate and the sample, so that the filtrate flows into the filtrate absorption chamber 702, and then is discharged through the filtrate output port 705. After the blocking valve 704 is pulled down and opened, the sample is discharged into the container below through the sample output channel 703 with a certain slope, thereby realizing the filtration and extraction of the sample.

[0051] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
