Description

Technical Field

[0001] This utility model relates to the field of miracidia incubation technology, and in particular to a fecal sample treatment device. Background Technology

[0002] In parasitology research, especially in miracidia hatching experiments involving parasites such as Schistosoma, precise fecal sample processing is a crucial prerequisite for ensuring the accuracy and reliability of experimental results. As a vital stage in the parasite's life cycle, the hatching efficiency of the miracidia is directly related to the purity of the eggs isolated from the fecal sample, and fecal sample processing is the core step in achieving efficient egg extraction. Currently, researchers and laboratory personnel need to obtain high-concentration, low-impurity fecal samples containing parasite eggs through fecal sample processing. This lays the foundation for subsequent steps such as isothermal culture, miracidia counting, and viability observation. Therefore, the scientific rigor and stability of fecal sample processing directly affect the progress and data quality of the entire miracidia hatching experiment.

[0003] Current fecal sample processing mainly relies on the traditional manual operation mode of "sampling-slurry preparation-filtration": operators first extract a quantitative sample from the fecal sample to be tested, add qualified clean water to prepare the slurry; then, the sample needs to be filtered step by step using a copper wire sieve and a 60-80 mesh nylon bag. The copper wire sieve initially removes coarse fibers and large impurities from the fecal sample, and the fine pores of the nylon bag trap parasite eggs. Finally, the remaining fecal sample tissue with parasite eggs is collected from the bag. However, the use of copper wire sieves and nylon bags requires frequent manual transfer of the slurry, the operation is cumbersome, and sample loss is easily caused by slurry spillage.

[0004] Therefore, it is necessary to design a fecal sample processing device to make it easier for operators to extract miracidia eggs from fecal samples. Utility Model Content

[0005] To address the above shortcomings, this utility model provides a fecal sample processing device that can more conveniently extract miracidia eggs from fecal samples.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fecal sample treatment device includes a slurry preparation section, a sealing cover, a filtration section, and a stirring section. A water inlet pipe communicating with the main body is provided on the upper side of the slurry preparation section. The sealing cover is detachably and sealingly installed on the upper part of the slurry preparation section. The stirring section is sealed and installed on the sealing cover and extends into the slurry preparation section. The filtration section is detachably and sealingly installed on the lower part of the slurry preparation section. A nylon cloth is attached to the lower part of the filtration section. This arrangement integrates the entire fecal sample treatment process. The water inlet pipe is connected to an external water source, and the pressure inside the device can be controlled by adjusting the water supply, thereby controlling the filtration speed.

[0007] Preferably, it also includes a support part, which includes a fixing ring, connecting rods, a support ring, and feet. The lower part of the filter part is funnel-shaped, the slurry preparation part is cylindrical, and there are multiple connecting rods. The multiple connecting rods are circumferentially and evenly fixed to the lower part of the fixing ring. The support ring is fixed to the lower part of the multiple connecting rods and is a funnel ring that fits into the funnel of the filter part. The slurry preparation part is installed inside the fixing ring, the filter part is installed inside the support ring, and there are multiple feet, which are correspondingly fixed to the multiple connecting rods.

[0008] Preferably, the sealing cap also includes a power switch, which is electrically connected to the stirring unit. The stirring unit and the power switch are electrically connected to an external power source, and the working state of the stirring unit is controlled by pressing the power switch.

[0009] Preferably, the mixing section includes a motor, a mounting plate, and mixing rods. The motor is sealed and mounted on the upper part of the sealing cover, and its drive shaft extends into the mixing section. The mounting plate is fixed to the lower part of the motor's drive shaft, and there are multiple mixing rods that are circumferentially and evenly fixed to the lower part of the mounting plate.

[0010] Preferably, the inner diameter of the lower part of the sealing cap is provided with a first thread, and the outer diameter of the upper part of the slurry preparation part is provided with a second thread that matches the first thread. The sealing cap is detachably installed on the second thread of the slurry preparation part through the first thread.

[0011] Preferably, the upper part of the filter section is open, and the inner diameter of the opening is provided with a fourth thread. The outer diameter of the lower part of the slurry preparation section is provided with a third thread that matches the fourth thread. The filter section is detachably installed at the third thread of the slurry preparation section via the fourth thread.

[0012] Preferably, the filter section further includes a copper wire screen plate, which is detachably installed at the bottom of the fourth thread of the filter section.

[0013] Preferably, the lower part of the filter section is funnel-shaped, and a sample outlet tube is provided at the bottom of the sample outlet tube. A fixing groove for fixing the nylon bag with cable ties is provided on the body of the sample outlet tube.

[0014] Preferably, the lower part of the support legs is also equipped with anti-slip pads.

[0015] Compared with existing technologies, the advantages of this invention are as follows: By integrating the functions of slurry preparation, stirring, and filtration into the same device, the slurry preparation section can directly hold fecal samples and inject clean water through the water inlet pipe. The stirring section extends into the slurry preparation section in a sealed manner to achieve mechanical stirring without manual intervention. The filtration section is sealed to the slurry preparation section so that the slurry flows directly into the filter without transfer. With the help of the sealing cover, the slurry splashes out and external contamination is prevented. This not only greatly simplifies the operation process and reduces manual complexity, but also effectively reduces the leakage and residue of samples during transfer, and improves the recovery rate of insect eggs. At the same time, mechanical stirring makes the fecal sample and clean water mix more evenly. Combined with the controllable filtration speed of the water inlet pipe, the purity of insect egg separation is guaranteed. Moreover, the automated stirring and continuous filtration greatly shorten the processing time of a single fecal sample. The detachable structure makes it easy to clean and reuse, and the overall experimental efficiency is significantly improved. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] The fecal sample processing device provided in this embodiment is mainly used for processing fecal samples in parasitology research for experiments involving the hatching of miracidia larvae of parasites such as Schistosoma, in order to achieve the purpose of efficiently extracting miracidia eggs from fecal samples. Figures 1-5 As shown, the device includes a slurry preparation unit 2, which is a cylindrical structure. A water inlet pipe 201 is welded to the upper side of the slurry preparation unit 2, connecting to the interior of the main body. One end of the water inlet pipe 201 is welded and fixed to the side wall of the slurry preparation unit 2 and communicates with the interior of the slurry preparation unit 2. The other end is used to connect to an external water source, such as a tap water faucet commonly used in laboratories or a special water storage device. Clean water that meets the conditions is injected into the slurry preparation unit 2 through the water inlet pipe 201 to provide the required water for the fecal sample slurry preparation. At the same time, the pressure inside the slurry preparation unit 2 and the entire device can be controlled by adjusting the outflow rate of the external water source, thereby controlling the speed of subsequent filtration operations.

[0023] A sealing cover 1 is provided on the upper part of the slurry preparation section 2. The sealing cover 1 has a circular cover structure, and its diameter matches the outer diameter of the slurry preparation section 2 to ensure a good sealing effect. To achieve a detachable sealing installation between the sealing cover 1 and the slurry preparation section 2, a first thread 101 is machined on the inner diameter surface of the lower part of the sealing cover 1, and a second thread 202 matching the first thread 101 is machined on the outer diameter surface of the upper part of the slurry preparation section 2. The pitch and thread depth of the second thread 202 are exactly the same as those of the first thread 101. During installation, the first thread 101 on the lower part of the sealing cover 1 and the second thread 202 on the upper part of the slurry preparation section 2 are screwed together to detachably install the sealing cover 1 on the upper part of the slurry preparation section 2. A polytetrafluoroethylene sealing tape can also be wrapped around the threaded connection to further enhance the sealing performance between the two and prevent slurry leakage from the connection during the slurry preparation process. The function of the sealing cover 1 is to seal the slurry preparation section 2 to prevent slurry splashing during slurry preparation, and at the same time provide a supporting foundation for the subsequent installation of the mixing section 5.

[0024] A stirring unit 5 is also installed on the sealing cover 1. The stirring unit 5 is used to stir the fecal sample and water in the slurry preparation unit 2, so that the fecal sample and water are fully mixed to form a uniform slurry. The stirring unit 5 includes a motor 501, a mounting plate 502, and a stirring rod 503. The motor 501 is installed on the upper part of the sealing cover 1 through a sealing mounting structure. Specifically, a mounting hole matching the diameter of the drive shaft of the motor 501 is opened at the center of the sealing cover 1. A rubber sealing ring is provided in the mounting hole. The drive shaft of the motor 501 passes through the mounting hole and extends into the slurry preparation unit 2. The body of the motor 501 is fixed to the upper surface of the sealing cover 1 by bolts. The rubber sealing ring can achieve a seal between the drive shaft of the motor 501 and the sealing cover 1, preventing the slurry from leaking from the mounting hole. A mounting plate 502 is fixedly connected to the lower part of the drive shaft of the motor 501 by welding. The mounting plate 502 is a circular metal plate, and its center is welded to the lower end of the drive shaft of the motor 501 to ensure that the motor 501 can drive the mounting plate 502 to rotate synchronously. At the lower part of the mounting plate 502, multiple stirring rods 503 are evenly welded circumferentially. The stirring rods 503 are made of metal, and there are three of them. One end of each stirring rod 503 is welded to the lower surface of the mounting plate 502, while the other end is free and extends vertically downwards to the lower middle part of the slurry preparation section 2. When the motor 501 drives the mounting plate 502 to rotate, the mounting plate 502 will drive the stirring rods 503 to move in a circular motion within the slurry preparation section 2, thereby stirring the fecal sample and water to fully mix them and form a uniform slurry.

[0025] A power switch 6 is also provided on the sealing cover 1 for convenient operation by the operator. The power switch 6 is electrically connected to the motor 501 of the stirring unit 5 via a wire, and the motor 501 of the stirring unit 5 and the power switch 6 are also electrically connected to an external power source via wires. By pressing the power switch 6, the operator can control the power on and off state of the motor 501 of the stirring unit 5, thereby controlling the operation and stop of the stirring unit 5. When the power switch 6 is pressed to power on the motor 501, the stirring unit 5 starts to work and perform stirring operations; when the power switch 6 is pressed again to de-power the motor 501, the stirring unit 5 stops working.

[0026] A filter section 4 is located at the lower part of the slurry preparation section 2. The filter section 4 is used to filter the uniformly stirred slurry in the slurry preparation section 2, removing coarse fibers, large impurities, etc. The upper part of the filter section 4 is open, and the lower part is funnel-shaped. This angle design facilitates the smooth downward flow of the slurry under gravity and allows for filtration. To achieve a detachable and sealed installation between the filter section 4 and the slurry preparation section 2, a fourth thread 402 is machined on the inner diameter surface of the upper opening of the filter section 4. Correspondingly, a third thread 203 matching the fourth thread 402 is machined on the outer diameter surface of the lower part of the slurry preparation section 2. The pitch and thread depth of the third thread 203 are exactly the same as those of the fourth thread 402. During installation, the fourth thread 402 at the upper opening of the filter section 4 and the third thread 203 at the lower part of the slurry preparation section 2 are screwed together to detachably install the filter section 4 at the lower part of the slurry preparation section 2. Similarly, a polytetrafluoroethylene sealing tape is wrapped around the threaded connection to enhance the sealing performance between the two and prevent slurry leakage from the connection.

[0027] Inside the filter section 4, specifically at the bottom of the fourth thread 402, a copper wire screen plate 401 is detachably installed. The copper wire screen plate 401 is made of brass, and its diameter matches the inner diameter of the opening at the top of the filter section 4. The aperture size of the copper wire screen plate 401 effectively removes coarse fibers and large impurities from the fecal slurry, while allowing insect eggs and fine slurry to pass through. The copper wire screen plate 401 is installed inside the filter section 4 via a slot structure. A ring-shaped slot is machined on the inner wall at the bottom of the fourth thread 402 of the filter section 4. The width and depth of the ring-shaped slot match the thickness of the copper wire screen plate 401. During installation, the copper wire screen plate 401 is inserted into this ring-shaped slot, allowing for detachable installation. After a period of use, the operator can remove the filter section 4 from the slurry preparation section 2 and then remove the copper wire screen plate 401 for cleaning or replacement to ensure effective filtration.

[0028] At the bottom of the funnel-shaped structure at the lower part of the filter section 4, a sample outlet tube 403 is welded. One end of the sample outlet tube 403 is welded and fixed to the bottom of the funnel-shaped structure of the filter section 4 and communicates with the interior of the filter section 4. The other end extends vertically downward to discharge the slurry after preliminary filtration by the copper wire sieve plate 401. A fixing groove 404 is machined around the body of the sample outlet tube 403 for fixing a nylon silk bag with cable ties. In actual use, the operator puts the opening of the nylon silk bag (using a 60-80 mesh nylon silk bag, which can effectively trap insect eggs) over the lower end of the sample outlet tube 403, and then uses cable ties to fix the opening of the nylon silk bag in the fixing groove 404 of the sample outlet tube 403. The cable ties should be tightened so that the opening of the nylon silk bag will not fall off the sample outlet tube 403 and the slurry will not leak from the gap between the bag opening and the sample outlet tube 403. After initial filtration by the copper wire sieve plate 401, the slurry flows out from the sample outlet tube 403 and enters the nylon silk bag. The nylon silk bag filters the slurry again to further remove fine impurities and trap insect eggs. Finally, fecal tissue containing insect eggs is collected in the nylon silk bag.

[0029] To ensure the stability of the entire device during use, the fecal sample treatment device also includes a support part 3, which is used to support and fix the slurry preparation part 2 and the filtration part 4. The support part 3 includes a fixing ring 301, connecting rods 302, a support ring 303, and a support foot 304. The fixing ring 301 is a circular metal ring whose inner diameter matches the outer diameter of the slurry preparation part 2, allowing the slurry preparation part 2 to be fitted into it. There are multiple connecting rods 302, preferably four in this embodiment. The four connecting rods 302 are circumferentially welded and fixed to the lower part of the fixing ring 301. Specifically, in the circumferential direction of the lower part of the fixing ring 301, one end of the connecting rod 302 is welded and fixed to the lower surface of the fixing ring 301, and the other end extends vertically downward to connect the support ring 303 and the support foot 304. A support ring 303 is welded and fixed at the lower part of the four connecting rods 302. The support ring 303 is a funnel ring that fits into the funnel-shaped structure of the filter section 4. The inner diameter of the support ring 303 matches the outer diameter of the upper part of the funnel-shaped structure of the filter section 4. When the filter section 4 is installed at the lower part of the slurry preparation section 2, the funnel-shaped structure of the filter section 4 can fit perfectly inside the support ring 303. The support ring 303 is connected to the fixing ring 301 through the connecting rods 302, thereby providing support for the filter section 4. On the side of each connecting rod 302, a support leg 304 is welded and fixed. The overall structure is L-shaped. One end of the support leg 304 is welded and fixed to the side wall of the connecting rod 302, and the other end extends vertically downward. The four support legs 304 correspond one-to-one with the four connecting rods 302, and together they support the entire support part 3 and the mixing part 2, sealing cover 1, stirring part 5 and filtering part 4 installed on the support part 3, so that the entire device can be placed stably on the experimental table.

[0030] To further enhance the stability of the device and prevent it from sliding due to slurry stirring or other external forces during use, an anti-slip pad 305 is glued to the bottom of each support leg 304. The anti-slip pad 305 is made of rubber and is circular in shape. Rubber has good anti-slip properties and can increase the friction between the support leg 304 and the experimental table surface, thereby effectively preventing the device from sliding during the experiment.

[0031] In actual use, the operator first assembles the components according to the above-mentioned connection relationship in the fecal sample treatment device of this embodiment: First, place the support part 3 on a stable experimental table, then fit the slurry preparation part 2 into the fixing ring 301 of the support part 3, so that the lower part of the slurry preparation part 2 is flush with the lower part of the fixing ring 301; then, screw the filter part 4 into the third thread 203 at the lower part of the slurry preparation part 2 through the fourth thread 402, ensuring that the funnel-shaped structure of the filter part 4 fits against the inner side of the support ring 303 of the support part 3; then, insert the copper wire sieve plate 401 into the annular groove of the filter part 4; then, connect the sealing cover 1 to the slurry preparation part through the first thread 101. 2. The second thread 202 on the upper part is screwed on and installed, and polytetrafluoroethylene sealing tape is wrapped around the thread to ensure a seal; then the motor 501 of the stirring part 5 is installed on the sealing cover 1, ensuring that the drive shaft of the motor 501 passes through the sealing cover 1 and extends into the slurry preparation part 2, and the mounting plate 502 and the stirring rod 503 are connected to the drive shaft of the motor 501; then the power switch 6 is installed on the sealing cover 1, and the power switch 6, the motor 501 and the external power supply are connected by wires; finally, the opening of the 60-80 mesh nylon silk bag is put over the lower end of the sample outlet tube 403 of the filter part 4, and it is fixed in the fixing groove 404 of the sample outlet tube 403 with a cable tie.

[0032] After assembly, the operator opens the sealing cover 1, adds a measured amount of fecal sample to be treated into the slurry preparation section 2, and then closes and tightens the sealing cover 1. Next, the external water source is turned on, and an appropriate amount of clean water is injected into the slurry preparation section 2 through the water inlet pipe 201. The amount of clean water injected is adjusted according to the amount of fecal sample, generally enough to fully soak the fecal sample and form a slurry. Then, the power switch 6 on the sealing cover 1 is pressed to power on the motor 501 of the stirring section 5. The motor 501 drives the mounting plate 502 and the stirring rod 503 to rotate, stirring the fecal sample and clean water in the slurry preparation section 2 until a uniform slurry is formed. After stirring is complete, the power switch 6 is pressed to turn off the motor 501, and the mixture is then processed as needed. To regulate the flow rate of the external water source and control the pressure within the slurry preparation section 2, thereby controlling the filtration speed of the slurry, the slurry in the preparation section 2 flows downwards under the action of gravity and pressure. It undergoes preliminary filtration through the copper wire sieve plate 401 in the filtration section 4 to remove coarse fibers, large impurities, etc. The slurry after preliminary filtration flows into the nylon silk bag through the sample outlet pipe 403. The nylon silk bag filters the slurry again, trapping insect eggs, while impurities flow out of the nylon silk bag with the excess slurry. After the slurry filtration is completed, the external water source is turned off, the tie is removed, and the nylon silk bag is removed from the sample outlet pipe 403. Fecal samples containing insect eggs can then be collected inside the nylon silk bag, completing the fecal sample treatment operation.

[0033] After use, the operator can disassemble each component for cleaning for the next use: First, unscrew the sealing cover 1 from the mixing section 2, then remove the motor 501 of the stirring section 5 from the sealing cover 1, and clean the sealing cover 1, motor 501, mounting plate 502 and stirring rod 503; next, unscrew the filter section 4 from the mixing section 2, and take out the copper wire screen plate 401 for cleaning; then remove the mixing section 2 from the fixing ring 301 of the support section 3 for cleaning; finally, clean the support section 3, sample outlet tube 403 and other components, and let them dry after cleaning for the next assembly and use.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
