Description

Technical Field

[0001] This utility model relates to the field of fecal worm egg collection technology, specifically to a parasite specimen collector. Background Technology

[0002] When a person is infected with different parasites, the corresponding parasite eggs can be found in their feces. Common examples include roundworm eggs, hookworm eggs, pinworm eggs, Clonorchis sinensis eggs, Fasciolopsis buski eggs, and amoebae trophozoites. Fecal examination is an important means of diagnosing intestinal parasitic diseases and medical protozoan diseases, and it is an important approach for the diagnosis and differentiation of diarrhea, etiological examination, and pathogen investigation.

[0003] Currently, most hospitals in China collect feces using plastic cups, small plastic bottles, or small plastic tubes with spoons. These samples contain many impurities that can interfere with microscopic examination of parasites, making it difficult to accurately examine parasite eggs in feces. Furthermore, the sample transfer process during microscopic examination involves multiple steps, which can easily lead to contamination. In addition, the samples inside the concave surface of the collection spoon in existing collectors are not easily dissolved.

[0004] Therefore, a parasite specimen collector was proposed. Utility Model Content

[0005] The purpose of this invention is to provide a parasite specimen collector that makes it easier to fully expose and dissolve fecal samples inside the concave surface of the collection spoon, and especially makes the microscopic examination process simpler and more hygienic.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides a parasite specimen collector, including a collection bottle. The upper end of the collection bottle is detachably connected to a main cap. A wall filter collection spoon is connected to the main cap. An end cap is connected to the upper end of the wall filter collection spoon. The main cap includes a cap body with a top hole. A flexible joint is connected to the top of the cap body. The flexible joint includes a folding tube, a sleeve ring connected to the upper end of the folding tube, and a thin-walled protrusion connected to the lower end of the folding tube. The lower edge of the thin-walled protrusion is sealed to the upper part of the cap body, and the sleeve ring is sealed to the wall filter collection spoon.

[0008] Preferably, the diameter of the folded tube gradually decreases as it approaches the sleeve ring.

[0009] Preferably, the folded tube gradually thins as it approaches the sleeve ring tube wall.

[0010] Preferably, a porous conduit is connected to the lower part of the cap body, and the axis of the porous conduit coincides with the axis of the sleeve ring and the collection bottle.

[0011] Preferably, the cap body is provided with an internal thread for threading with the upper end of the collection bottle.

[0012] Preferably, the main cover is made of polyethylene plastic in one piece.

[0013] Preferably, the wall filter collection spoon includes a collection rod, the upper center of which has a central hole, and the upper circumferential wall has a connecting groove for sealing and connecting the sleeve ring and a plurality of rod filter holes. The rod filter holes are connected to the central hole and are located below the connecting groove. The lower part of the collection rod has a groove plate, and the lower end of the groove plate has a tongue-shaped sampling end.

[0014] Preferably, the upper part of the collection rod is provided with an end cap groove for locking the end cap.

[0015] Preferably, the groove plate has multiple toothed grooves symmetrically arranged on both sides.

[0016] Preferably, the groove plate is bent so that the groove surface is slightly convex.

[0017] Preferably, a filter cover is connected to the peripheral wall of the collection rod.

[0018] Preferably, the filter cover is a conical filter cover, which is a cone shape that is larger at the top and smaller at the bottom. The wall of the conical filter cover is provided with a number of filter holes. The lower end of the conical filter cover is connected to the outer peripheral surface of the collection rod near the groove plate, and the upper port faces the upper end of the collection rod. The axis of the conical filter cover coincides with the axis of the collection rod.

[0019] Preferably, the upper port of the conical filter shroud can be inserted into the porous conduit.

[0020] Preferably, the collection bottle and the wall filter collection spoon are both made of polypropylene plastic in one piece.

[0021] Preferably, the bottom surface of the collection bottle is provided with an upwardly convex groove.

[0022] Preferably, the perimeter of the collection bottle is covered with a writing sticker.

[0023] Preferably, the peripheral wall of the collection bottle is provided with a capacity scale.

[0024] Due to the adoption of the above technical solutions, the advantages of this utility model are as follows:

[0025] 1. The groove plate provided by this utility model is slightly curved, making the groove surface slightly convex. The groove plate is provided with multiple toothed grooves on the side for pre-bending and breaking. After adding physiological saline through the upper end of the collection rod and capping it, the upper and lower ends are pinched by hand to make the lower sampling end of the collection rod abut against the upper convex groove at the bottom of the bottle body. This makes it easy to force the groove plate to bend significantly according to the pre-bending trend and / or partially break. This makes the groove surface of the groove plate protrude outward, allowing the sample to be more fully exposed to contact with physiological saline, which is beneficial for the rapid dissolution of the sample in the groove.

[0026] 2. The main cover provided by this utility model has a flexible joint at the upper end. The flexible joint is sealed and fixedly connected to the collection rod through the upper end of the folding tube. When this utility model is in a sealed state, when the end cover is pressed down to move the collection rod downward, the upper end of the folding tube is easily driven downward by the collection rod (the diameter of the folding tube gradually decreases as it approaches the sleeve ring, and the tube wall gradually becomes thinner). At the same time, the folding tube is in a state similar to an inward fold, so that the thin-walled protrusion is hardly compressed during the downward movement of the collection rod, and the collection rod can be pressed down smoothly.

[0027] 3. The conical filter cover and rod filter holes provided by this utility model are conducive to the efficient filtration of large particle residues.

[0028] 4. When sampling and examining the specimen under a microscope, this invention only requires removing the top cover and dropping the sample like squeezing eye drops. The specimen transfer steps during the microscopic examination are reduced, making it less prone to contamination and making the microscopic examination process simpler and more hygienic.

[0029] 5. This utility model has low cost and is easy to promote. Attached Figure Description

A flexible joint 12 is connected to the top of the cover body 11. The flexible joint 12 includes a folded tube 122, a sleeve ring 123 connected to the upper end of the folded tube 122, and a thin-walled protrusion 121 connected to the lower end of the folded tube 122. The lower edge of the thin-walled protrusion 121 is sealed to the top of the cover body 11. The sleeve ring 123 is sealed to the wall filter collection spoon 20. The axis of the sleeve ring 123 coincides with the axis of the porous conduit 113 and the collection bottle 30. The diameter and wall of the folded tube 122 gradually decrease as it approaches the sleeve ring 123. (See [reference]). Figure 1 , Figure 3 , Figure 4 .

[0043] The wall-mounted filter collection spoon 20 includes a collection rod 21 and a conical filter cover 22. The upper center of the collection rod 21 has a central hole 212. The upper circumferential wall has an end cap groove 211, a connecting groove 213 for sealing the connecting sleeve ring 123, and multiple rod filter holes 214. The end cap groove 211 is near the upper port of the central hole 212. The rod filter holes 214 communicate with the central hole 212 and are located below the connecting groove 213. The lower part of the collection rod 21 has a groove plate 215. Multiple toothed grooves 216 are symmetrically arranged on both sides of the groove plate 215. The lower end of the 15 is provided with a tongue-shaped sampling end 217, and the groove plate 215 is slightly curved, making the groove surface slightly convex; the conical filter cover 22 is a cone shape that is larger at the top and smaller at the bottom. The wall of the conical filter cover 22 is provided with several filter holes 222 for filtration. The lower end of the conical filter cover 22 is connected to the outer peripheral surface of the sampling rod 21 near the groove plate 215, and the upper port faces the upper end of the sampling rod 21. The axis of the conical filter cover 22 coincides with the axis of the sampling rod 21. The upper port of the conical filter cover 22 is slidably inserted into the porous conduit 113. See Figure 1 , Figure 3 , Figure 4 , Figure 5 .

[0044] The upper end of the collection bottle 30 is provided with a threaded opening 33 for the internal thread 112 on the screw cap body 11, and the center of the inner surface of the bottom is provided with an upwardly convex bottom groove 32. See Figure 1 , Figure 2 , Figure 6 .

[0045] In this embodiment, the main cover 10 is made of polyethylene plastic in one piece; the collection bottle 30 and the wall filter collection spoon 20 are both made of polypropylene plastic in one piece.

[0046] The sampling method used in this utility model:

[0047] S1. Unscrew the main cover 10, pinch the end where the end cover 1 is located, and take a sample using the sampling end 217;

[0048] S2. After sampling is completed, the collected sample is put back into the collection bottle along with the sampling end 217, and the main cap 10 is tightened and sent for testing on the collection bottle 30.

[0049] Specific sampling requirements shall be carried out in accordance with the standard procedures for collecting fecal worm egg specimens, and will not be repeated here.

[0050] The present invention relates to a microscopic sampling method:

[0051] S1. After receiving the specimen, remove the end cap 1 and inject physiological saline into the center hole 212 (the physiological saline further flows through the rod filter hole 214 into the cone filter hood 22, and finally flows from the hood filter hole 222 into the collection bottle 30 to contact the specimen).

[0052] S2. Replace end cap 1. Press end cap 1 and the bottom of collection bottle 30 with your fingers until end cap 1 moves to the bottom. (During this process, the sampling end 217 of the lower end of the collection rod 21 rests in the upper convex groove 32. As the collection rod 21 moves downward, the connecting groove 213 of the collection rod 21 drives the sleeve ring 123 to move downward, causing the folded part 122 to gradually fold inward from top to bottom. The groove plate 215 and the sampling end 217 are gradually bent, especially at the toothed groove 216, causing the groove surface of the groove plate 215 to protrude outward. See...) Figure 6 Then shake until the sample dissolves;

[0053] S3. After removing end cap 1 with the end facing upwards, turn the port of the central hole 212 toward the glass slide and gently squeeze the thin-walled protrusion 121 (the specimen solution enters the central hole 212 through the cover filter hole 222 and the rod filter hole 214). Drop the specimen solution onto the glass slide for microscopic examination and replace end cap 1.

[0054] After microscopic examination, replace end cap 1 and place the collector into the collection container as required.
