DETAILED DESCRIPTION

[0029] The following is a further detailed description of the specific implementation methods of the present invention, such as the shape, structure, relative position and connection relationship between the various components involved, the function and working principle of each part, the manufacturing process and operation method, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0030] like Figure 1 As shown, a sputum microorganism detection biosafety collection processor has an end cover 8 at one end of a cylindrical shell 13, and the other end is sealed by a back cover 15. A piston 3 is arranged in the shell 13, and the rear end of the piston 3 is connected to one end of a push rod 2. A guide hole 14 is arranged in the center of the back cover 15. The other end of the push rod 2 extends out of the shell 13 through the guide hole 14 and is connected to the push handle 1. A waste liquid outlet 10 is arranged on the end cover 8, forming a structure similar to that of a syringe.

[0031] The waste liquid outlet 10 includes a connecting cover and a liquid outlet. One side of the connecting cover is an open side, and the other side is connected to the liquid outlet. The edge of the open side of the connecting cover is fixed on the shell 13. The waste liquid outlet 10 has a circle of snap-fit ​​structure outside, and a waste liquid cup 9 is mounted on the snap-fit ​​structure.

[0032] A partition 6 is provided near the front end of the outer shell 13, and a first filter membrane 5 is fixed on the partition 6. The pores of the first filter membrane 5 cannot allow large molecular viruses to pass through, but can allow decomposed small molecules to pass through. Protruding sample ports are provided on the outer shell 13 on both sides of the partition 6. The sample port on the outer shell 13 between the partition 6 and the end plate is a sample outlet 11 for discharging liquid, and the other sample port is a sample inlet 12 for inhaling liquid. A sealing cover 16 is provided on the waste liquid outlet 10, the sample outlet 11 and the sample inlet 12. The sample outlet 11 and the sample inlet 12 are equipped with a rubber hose that is connected when the sealing cover 16 is removed. The sealing cover 16 is preferably a threaded cover structure, which can avoid detachment when the push rod 2 is pressed down, and can also ensure air tightness.

[0033] A sponge layer 4 is fixed on the piston 3, and the sponge layer 4 is filled with a pretreatment solution for pretreatment of the collected sample. The pretreatment solution is determined according to the type of sample. The partition 6 and the end cover 8 are grid-shaped plates. The first filter membrane 5 is fixed on the partition 6 facing the side of the back cover 15. The scouring pad layer 17 on the partition 6 is fixed on the first filter membrane 5. The end cover 8 is provided with a second filter membrane 7 on the side facing the partition 6, so that the partition 6 and the end cover 8 can support the filter membrane to prevent the filter membrane from falling off. The pores of the first filter membrane 5 are larger than the pores of the second filter membrane 7. The second filter membrane 7 can only allow water molecules to pass through, and the decomposed viruses cannot pass through, and remain in the processor, waiting for the unified treatment of medical waste in the future.

[0034] A scouring pad layer 17 is provided on the facing surfaces of the sponge layer 4 and the partition 6. The scouring pad layer 17 can interact with each other to crush the sputum, so that the sputum sample is fully processed and can quickly pass through the first filter membrane 5. The guide hole 14 is a circular hole, and the push rod 2 is a cylindrical rod-shaped structure. The outer diameter of the push rod 2 is smaller than the inner diameter of the guide hole 14, which is convenient for rotating the push rod 2. The push rod 2 is fixedly connected to the piston 3, which further drives the piston 3 and the scouring pad layer 17 above to rotate, thereby achieving the purpose of crushing the sputum.

[0035] A card slot is provided on the push rod 2, in which a plug-in that can be selectively inserted or removed is embedded. When the plug-in is inserted into the card slot, it serves as a limit mechanism for pushing the push rod 2 into the shell 13. When the plug-in contacts the back cover 15, there is a gap between the two scouring pad layers 17 to avoid operation, pushing the push rod 2 to squeeze out the pretreatment solution in the sponge layer 4.

[0036] The operation method of the above-mentioned sputum microbiological detection biosafety collection processor is as follows:

[0037] Step 1, remove the sealing cover 16 on the sample inlet 12, and put a rubber hose on the sample inlet 12;

[0038] Step 2, place the rubber hose into the sample container, and then pull the push handle 1 outward to suck the sample into the housing 13;

[0039] Step 3: Remove the insert;

[0040] Step 4, push the push handle 1 to make the two layers of scouring pad 17 contact each other, remove the rubber hose on the sample inlet 12, put the sealing cover 16 on the sample inlet 12, and rotate the push handle 1 to make the two layers of scouring pad 17 crush the sputum;

[0041] Step 5, remove the sealing cover 16 on the sample outlet 11, make the sample outlet 11 face upward, push the push handle 1 to inject the sample and the pretreatment solution into the cavity between the partition 6 and the end cover 8;

[0042] Step 6, cover the sample inlet 12 with a sealing cover 16, and let it stand for a set time to allow the sample and the pretreatment solution to fully react;

[0043] Step 7, remove the sealing cover 16 on the sample outlet 11, and put a rubber hose on the sample outlet 11;

[0044] Step 8, push the push handle 1 to let the sample be discharged from the rubber hose;

[0045] Step 9, remove the rubber hose on the sample outlet 11, and put the sealing cover 16 on the sample outlet 11;

[0046] Step 10: The sealing cover 16 on the waste liquid outlet 10 is used to push the push handle 1 to inject the waste liquid in the housing 13 into the waste liquid cup 9.

[0047] In this mode of operation, the first filter membrane 5 cannot allow large virus molecules to pass through, and can only allow the virus to pass through after being inactivated and decomposed into small molecules, thus avoiding contamination; when coming out of the sampling area, the output liquid will not carry the acquired virus, and the second filter membrane 7 can only filter out water molecules, and other toxic and harmful impurities will remain in the collector.

[0048] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
