Description

Technical Field

[0001] This utility model belongs to the field of detection device technology, specifically a quantitative sampling and smearing integrated tool for parasite detection. Background Technology

[0002] In parasitic disease diagnosis techniques, parasite egg detection is an important method for diagnosing intestinal or tissue parasitic infections. It mainly involves detecting parasite eggs in feces and other excrement using a microscope.

[0003] The modified Kato thick smear method is a commonly used approach. The procedure involves laying a nylon cloth flat on the feces, gently pressing it with a scraper to ensure close adhesion, and then scraping the feces from above the cloth. The scraped sample is then filled into the central hole of a quantitative plate until it is full and leveled. A sheet of pre-soaked hydrophilic transparent cellophane is taken, excess soaking solution is shaken off, and it is placed over the feces. Another clean glass slide is used to gently press the feces sample evenly and perpendicularly in a cross shape, ensuring the feces under the cellophane spread evenly and remain within the slide, forming a circular fecal film of approximately 2 cm in diameter. The cellophane is held in place with the thumb, and the slide used to press the sample is gently removed. The prepared modified Kato thick smear is left to stand at room temperature to allow it to become transparent, but the transparency time should not exceed 2 hours. The transparent modified Kato thick smear is then examined under a biological microscope.

[0004] The existing technology has the following defects and directions for improvement: (1) In the existing smearing tool technology, sampling and scraping are designed independently, and the operation steps are relatively complicated, which affects the efficiency of detection. (2) In addition, manually scraping the sample makes it difficult to control the thickness.

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

[0027] like Figures 1 to 5As shown in the figure, an integrated quantitative sampling and smear tool for parasite detection according to an embodiment of the present invention includes a sampling rod 1; a quantitative spoon 11 is fixedly connected to one end of the sampling rod 1; an adjustment component is provided at the other end of the sampling rod 1; a scraper 12 is installed on the sampling rod 1 through the adjustment component; a protective component is detachably installed in the middle of the sampling rod 1; the sampling rod 1 includes a fastening component through the adjustment component; and an anti-slip component is included near the adjustment component. During operation, when sampling, the sampling rod 1 is held and the quantitative spoon 11 is used to sample the feces quantitatively. After sampling, the feces are placed on a glass slide, the scraper 12 is adjusted to a suitable position through the adjustment component and fixed through the fastening component, and then flipped over for sampling. Rod 1 presses the adjustment component onto the glass slide. Sliding sampling rod 1 and scraper 12 evenly coat the sample onto the glass slide. When holding sampling rod 1, the fingers contact the anti-slip component, increasing the friction between the hand and sampling rod 1. When flipping sampling rod 1, the protective component protects the hand. Through the above structure, the quantitative spoon 11 quantitatively samples the sample and the scraper 12 evenly coats the sample onto the glass slide, forming an integrated coating structure. This realizes the functions of sample collection and uniform coating, solving the problem of cumbersome operation steps during sampling and coating caused by the separate design of sampling and scraper. It improves the integration of the device, simplifies the operation steps of sampling and coating during detection, and improves the efficiency of detection.

[0028] like Figures 1 to 5As shown, the adjustment assembly includes a scraper frame 2, a limiting block 21, a first lead screw 22, a first adjustment knob 23, and a sliding rod 24; the scraper frame 2 is fixedly connected to the end of the sampling rod 1 away from the measuring spoon 11; the limiting block 21 is fixedly connected to the inner wall of the scraper frame 2 away from the sampling rod 1; a pair of limiting blocks 21 are provided on the inner wall of the scraper frame 2, and are symmetrically arranged; the first adjustment knob 23 is rotatably connected to the middle part of the scraper frame 2 near the sampling rod 1; the first lead screw 22... One end is rotatably connected to the end of the scraper 12 near the sampling rod 1; the first lead screw 22 is threadedly connected to the first adjusting knob 23; the end of the first lead screw 22 away from the scraper 12 slides in the middle of the scraper frame 2 and the sampling rod 1; the sliding rod 24 is fixedly connected to the side wall of the scraper 12; a pair of sliding rods 24 are provided on the side wall of the scraper 12 and are symmetrically arranged; the sliding rods 24 are slidably connected to the inner side wall of the scraper frame 2; a limiting component is provided on the side wall of the scraper 12 near the limiting block 21. During operation, when the coating thickness needs to be adjusted according to the testing requirements, the first adjustment knob 23 is turned, which drives the first lead screw 22 to rotate. The first lead screw 22 moves in the middle of the scraper frame 2, and the sliding rod 24 guides the scraper 12. The first lead screw 22 drives the scraper 12 to move to the appropriate position. Holding the sampling rod 1, the scraper frame 2 is clamped on both sides of the glass slide, so that the limiting block 21 contacts the surface of the glass slide. The sampling rod 1 is pulled, so that the scraper 12 slides on the glass slide and evenly coats the sample on the glass slide. Through the above structure, turning the first adjustment knob 23 drives the first lead screw 22 to rotate and adjust the position of the scraper 12, forming a coating thickness adjustment structure. This realizes the function of adjusting the position of the scraper 12 and controlling the coating thickness, solving the problem of inconvenient thickness control caused by manually scraping the sample, improving the uniformity of sample coating, and improving the convenience of adjusting the coating thickness of the device.

[0029] like Figure 3 and Figure 4As shown, the fastening assembly includes a second lead screw 3, a second adjusting knob 31, a top block 32, and a rubber pad 33. The second lead screw 3 is threadedly connected to the middle of the scraper frame 2 near the first adjusting knob 23. The second adjusting knob 31 is fixedly connected to the end of the second lead screw 3 away from the first adjusting knob 23. The top block 32 is rotatably connected to the end of the second lead screw 3 near the first adjusting knob 23. The rubber pad 33 is fixedly connected to the side wall of the top block 32 near the first adjusting knob 23. During operation, after the scraper 12 is adjusted, the second adjusting knob 31 is turned, causing the second lead screw 3 to rotate in the middle of the scraper frame 2. The second lead screw 3 then causes the top block 32 and the rubber pad 33 to move closer to the first adjusting knob 23, so that the rubber pad 33 is in contact with the first adjusting knob 23. The outer wall of knob 23 contacts and presses, fixing the first adjustment knob 23 in the middle of the scraper holder 2. Before turning the first adjustment knob 23, the second adjustment knob 31 is turned in the opposite direction to make the rubber pad 33 move away from the outer wall of the first adjustment knob 23. Through the above structure, turning the second adjustment knob 31 drives the top block 32 and the rubber pad 33 to approach the first adjustment knob 23 and press and fix the first adjustment knob 23, forming the fastening structure of the first adjustment knob 23. This realizes the function of pressing and fixing the first adjustment knob 23 after adjustment, solving the problem that the position of the scraper 12 will shift due to the rotation after the first adjustment knob 23 is adjusted, improving the stability of the scraper 12 during use, and improving the uniformity of the scraper 12 when coating the sample.

[0030] like Figure 1 and Figure 5 As shown, the protective assembly includes a rubber band 4 and an elastic protective cover 41. The rubber band 4 is detachably installed on the outer wall of the sampling rod 1. The elastic protective cover 41 is fixedly connected to the outer wall of the rubber band 4. During operation, when using the metering spoon 11, the rubber band 4 is pulled close to the scraper frame 2. When using the scraper 12, the rubber band 4 is pulled close to the metering spoon 11. When sliding the sampling rod 1 and the scraper 12, the elastic protective cover 41 blocks the metering spoon 11 from the hand, preventing the sample from falling from the metering spoon 11. Through the above structure, the setting of pulling the rubber band 4 to move the elastic protective cover 41 to a suitable position to block the metering spoon 11 from the hand forms a protective structure, realizing the function of isolating and protecting the metering spoon 11 from the hand, solving the problem of sample falling from the metering spoon 11 and contaminating the hand, and reducing the situation where residual sample falls from the metering spoon 11 onto other items when sliding the scraper 12.

[0031] like Figure 1 and Figure 2As shown, the anti-slip component includes a silicone pad 5 and silicone protrusions 51. The silicone pad 5 is fixedly connected to the side wall of the sampling rod 1 near the scraper holder 2. A pair of silicone pads 5 are provided on the side wall of the sampling rod 1, and they are arranged symmetrically. The silicone protrusions 51 are fixedly connected to the side wall of the silicone pad 5 away from the sampling rod 1. Multiple sets of silicone protrusions 51 are provided on the side wall of the silicone pad 5. During operation, when the hand holds the sampling rod 1 and slides the scraper 12, the hand comes into contact with the silicone pad 5 and the sampling rod 1, increasing the friction between the hand and the sampling rod 1. Through the above structure, the silicone pad 5 and the silicone protrusions 51 are arranged to increase the friction when they come into contact with the hand, forming an anti-slip structure of the device, reducing the slippage that occurs when the hand holds the sampling rod 1 and slides the scraper 12.

[0032] like Figure 3 and Figure 4 As shown, the limiting component includes a limiting rod 6; the limiting rod 6 is fixedly connected to the side wall of the scraper 12 near the sliding rod 24; a pair of limiting rods 6 are provided on the side wall of the scraper 12 and are symmetrically arranged; the limiting rod 6 is slidably connected to the inner side wall of the scraper frame 2; during operation, when the scraper 12 slides on the inner side wall of the scraper frame 2, it drives the limiting rod 6 to slide on the inner side wall of the scraper frame 2, and the limiting rod 6 cooperates with the limiting block 21 to limit the scraper 12; through the above structure, the limiting rod 6 limits the sliding distance of the scraper 12, forming a limiting structure, reducing the possibility of the scraper 12 detaching from the middle of the scraper frame 2, and improving the stability of the scraper 12 when moving in the middle of the scraper frame 2.

[0033] like Figure 3 As shown, the outer walls of the first adjustment knob 23 and the second adjustment knob 31 are provided with anti-slip textures. During operation, when the first adjustment knob 23 and the second adjustment knob 31 are turned, the anti-slip textures come into contact with the hand, increasing the friction between the hand and the first adjustment knob 23 and the second adjustment knob 31, and reducing the slippage that occurs when turning the first adjustment knob 23 and the second adjustment knob 31.

[0034] During operation, when sampling, the sampling rod 1 is held and a quantitative spoon 11 is used to collect a quantitative sample of feces. After sampling, the feces are placed on a glass slide. The scraper 12 is adjusted to a suitable position using the adjustment component and fixed with the fastening component. The sampling rod 1 is flipped over to press the adjustment component onto the glass slide. The sampling rod 1 is slid, and the scraper 12 evenly spreads the sample onto the glass slide. When holding the sampling rod 1, the fingers contact the anti-slip component to increase the friction between the hand and the sampling rod 1. When flipping the sampling rod 1, the protective component protects the hand. When the coating thickness needs to be adjusted according to the testing requirements, the first adjustment lever is turned. Adjusting knob 23 drives the first lead screw 22 to rotate, causing the first lead screw 22 to move in the middle of the scraper holder 2. Sliding rod 24 guides the scraper 12, and the first lead screw 22 moves the scraper 12 to a suitable position. Holding sampling rod 1, the scraper holder 2 is secured to both sides of the glass slide, so that the limiting block 21 contacts the surface of the glass slide. Pulling sampling rod 1 causes the scraper 12 to slide on the glass slide and evenly coat the sample onto the slide. After the scraper 12 is adjusted, turning the second adjusting knob 31 causes the second lead screw 3 to rotate in the middle of the scraper holder 2. The second lead screw 3 then... The top block 32 and the rubber pad 33 move closer to the first adjusting knob 23, so that the rubber pad 33 contacts and presses against the outer wall of the first adjusting knob 23, fixing the first adjusting knob 23 in the middle of the scraper frame 2. Before turning the first adjusting knob 23, turn the second adjusting knob 31 in the opposite direction to move the rubber pad 33 away from the outer wall of the first adjusting knob 23. When using the measuring spoon 11, pull the rubber band 4 closer to the scraper frame 2. When using the scraper 12, pull the rubber band 4 closer to the measuring spoon 11. When sliding the sampling rod 1 and the scraper 12, the elastic protective cover 41 blocks the space between the measuring spoon 11 and the hand, and the sample will be drawn from the measuring spoon 11. The falling sample is blocked; when the hand holds the sampling rod 1 and slides the scraper 12, the hand comes into contact with the silicone pad 5 and the sampling rod 1, increasing the friction between the hand and the sampling rod 1; when the scraper 12 slides on the inner wall of the scraper frame 2, it drives the limiting rod 6 to slide on the inner wall of the scraper frame 2, and the limiting rod 6 cooperates with the limiting block 21 to limit the scraper 12; when the first adjustment knob 23 and the second adjustment knob 31 are turned, the anti-slip texture comes into contact with the hand, increasing the friction between the hand and the first adjustment knob 23 and the second adjustment knob 31, reducing the slippage that occurs when turning the first adjustment knob 23 and the second adjustment knob 31.
