[0042] The stool specimen collection auxiliary device of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0043] Reference Figures 1 to 3 As shown, the stool specimen collection auxiliary device provided according to the embodiment of this utility model includes a support towel 10 and two connecting pieces 20.

[0044] Specifically, the support blanket 10 is made of water-soluble material and is used to collect the patient's feces. The support blanket 10 has a sheet-like structure and can be rectangular, oval, or circular in shape, with a size smaller than the toilet bowl opening H30 of the toilet 30, so that it can be suspended within the opening H30. The water-soluble material ensures that the support blanket 10 is quickly dissolved by flushing the toilet 30 after use, achieving environmentally friendly treatment without the need for additional cleaning. Furthermore, the support blanket 10 has a large supporting area, making it easy to observe the location of abnormal stool and facilitating accurate sampling of the abnormal portion of the stool (clinical testing requires that the stool sample include the relatively abnormal portion), indirectly saving medical costs.

[0045] One of the two connecting pieces 20 is located at one end of the support towel 10, and the other of the two connecting pieces 20 is located at the other end of the support towel 10. The two connecting pieces 20 are used to fix both ends of the support towel 10 to the edge of the toilet 30, so that the support towel 10 is located in the toilet opening H30. Each connecting piece 20 is provided with an adhesive piece 201 for bonding and fixing the connecting piece 20 to the edge of the toilet 30, so that the support towel 10 is suspended in the toilet opening H30. In use, the two connecting pieces 20 can be tightly bonded to the edge of the toilet 30 using the adhesive piece 201, and then the toilet seat 31 can be placed on top. This prevents direct contact with the skin during use, and the toilet seat 31 can also hold down the adhesive piece, thus ensuring that the support towel 10 is more stably and securely suspended in the toilet opening H30 during use, and is less prone to displacement.

[0046] It should be noted that the overall length of the two connecting pieces 20 after being connected to the support cloth 10 can be greater than the diameter of the toilet opening H30. This ensures that when the two connecting pieces 20 are fixed to the edge of the toilet 30 by the adhesive 201, the support cloth 10 can naturally sink a certain distance, so that a certain height difference is formed between the support cloth 10 and the toilet opening of the toilet 30, preventing the support cloth 10 from being too close to the user's buttocks during use and causing discomfort.

[0047] A tear H12 is formed at the connection between the connecting piece 20 and the support towel 10 to separate the support towel 10 from the connecting piece 20 after sampling. For example, the tear H12 is a row or multiple rows of dotted holes arranged in a matrix, so that the support towel 10 can be torn apart at the tear H12 position with a slight shearing force, thus facilitating the disposal of the used support towel 10 into the toilet 30 for flushing and dissolution.

[0048] During the sampling process, the support towel 10 is first unfolded to form a roughly concave shape, and the connecting pieces 20 at both ends are attached to the edge of the toilet 30 using adhesive pieces 201, so that the support towel 10 is suspended in the toilet opening H30. Then, the toilet seat 31 is closed, and the patient simply sits on the toilet seat 31 as usual. The support towel 10 quickly and accurately collects the patient's feces on the towel surface, ensuring that the stool sample does not come into contact with the water in the toilet 30. An appropriate amount of stool sample is then collected from the support towel 10 into a sample container (e.g., a test tube). Because the collection process is simple, hygienic, and reliable, it effectively improves the efficiency of sample collection and the accuracy of test results, while also reducing the complexity of subsequent sample processing for medical staff.

[0049] After sampling, the support cloth 10 and the connecting piece 20 can be easily separated along the tear H12. After separation, the support cloth 10 falls into the toilet bowl along with the feces and is dissolved by flushing, achieving quick and pollution-free cleaning; while the connecting piece 20 is disposed of in the trash can in the conventional way, avoiding secondary pollution to the environment.

[0050] According to the fecal specimen collection auxiliary device provided in this embodiment, a support towel 10 is made of water-soluble material. Connecting pieces 20 are provided at both ends of the support towel 10, and adhesive pieces 201 and tear marks H12 are pre-set on the connecting pieces 20. In use, the connecting pieces 20 can be attached to the edge of the toilet bowl 30 using the adhesive pieces 201, allowing the support towel 10 to suspend in the toilet bowl opening H30 to collect the patient's feces, facilitating convenient and quick sampling, reducing sample contamination, and ensuring more accurate and reliable test results. After sampling, the support towel 10 is quickly separated from the connecting pieces 20 at the tear mark H12 and discarded into the toilet bowl to dissolve. The connecting pieces 20 are disposed of in the trash can. This device is convenient, environmentally friendly, pollution-free, and odorless. Therefore, this invention has a simple structure, facilitates sampling, provides convenient subsequent processing, saves medical costs associated with reprocessing contaminants, and is highly practical.

[0051] In one embodiment of this utility model, the middle portion of the support towel 10 has a pleated structure 10a, so that the support towel 10 sinks and indents after bearing the weight of feces. The pleated structure 10a adopts a pre-made folded line or wavy convex and concave structure, which can be realized by mechanical embossing or hot pressing process, so that the support towel 10 is in a flat state when not bearing the weight of feces, but the middle portion can quickly sink and indent after being subjected to pressure, forming a natural collection groove.

[0052] During use, when the patient's feces fall into the support cloth 10, the weight of the feces will cause the pleated structure 10a in the middle part to unfold and sink a certain distance, but without contacting the water in the toilet. This forms a concave area on the support cloth 10, namely a collection groove, which can more effectively contain and fix the feces and prevent the feces from slipping off the support cloth 10 into the toilet 30.

[0053] In this embodiment, by utilizing the expansion and contraction characteristics of the pleated structure 10a, the feces can be quickly collected as they fall, thus improving the accuracy and reliability of feces collection and ensuring that users can effectively collect feces samples, thereby increasing the sample collection rate.

[0054] In one embodiment of this utility model, the upper surface of the support towel 10 is provided with an absorbent layer 11, which is made of a water-soluble material to absorb moisture from feces. The absorbent layer 11 can be prepared by spraying, coating or hot pressing processes to form a good bond between the two layers.

[0055] The absorbent layer 11 has good water solubility and moisture absorption properties. This ensures that the absorbent layer 11 can quickly absorb the moisture in feces when it comes into contact with feces, preventing the moisture in the feces from coming into contact with the support cloth 10 too early and causing the support cloth 10 to start dissolving too early, thereby ensuring that the support cloth 10 maintains a good support effect.

[0056] During use, when a patient defecates, the liquid components are first rapidly absorbed by the absorbent layer 11 on the support towel 10. During contact between the stool and the absorbent layer 11, the absorbent layer 11 effectively separates excess water from the stool, causing the stool to accumulate on the support towel 10. The support towel 10 is not easily dissolved by the water in the stool, thus effectively supporting and holding the collected stool. Furthermore, the stool with absorbed water is easier to sample manually, improving the convenience of stool sampling.

[0057] In this embodiment, the absorbent layer 11 not only prevents premature dissolution caused by direct contact between the water in the feces and the support cloth 10, but also effectively separates excess water by rapidly absorbing the liquid in the feces, ensuring that the support cloth 10 can stably support and collect the feces, thereby significantly improving the convenience of sampling and the accuracy of sample detection.

[0058] In one embodiment of the present invention, the absorbent layer 11 includes an upper absorbent layer 111 and a lower absorbent layer 112, wherein the water absorption capacity of the lower absorbent layer 112 is greater than that of the upper absorbent layer 111.

[0059] The upper absorbent layer 111 is located on the surface and is mainly used to quickly absorb the liquid components in the feces upon initial contact, thereby initially isolating the liquid and protecting the main body of the support towel 10 from premature wetting. The lower absorbent layer 112 is located below the upper absorbent layer 111, that is, between the upper absorbent layer 111 and the support towel 10. It has higher absorbency and absorbs the remaining water in the feces, ensuring that excess liquid in the feces is fully absorbed and preventing water from penetrating into the support towel 10, thus preventing the support towel 10 from dissolving prematurely.

[0060] By combining the upper absorbent layer 111 and the lower absorbent layer 112—that is, by creating a gradient configuration in terms of absorbency—this embodiment achieves the goal of quickly isolating moisture in the initial stage and preventing fecal moisture from directly affecting the support towel 10. Simultaneously, the lower absorbent layer 112 effectively locks in excess liquid in the subsequent enhanced absorption, improving the support effect of the support towel 10. Furthermore, this multi-layered structure also strengthens the structural strength of the support towel 10, further enhancing its supportive effect.

[0061] In one embodiment of this utility model, side guards 101 are formed on both sides of the support towel 10 in the width direction, and the side guards 101 and the support towel 10 define a downwardly recessed collection cavity. Exemplarily, the side guards 101 are formed by partially folding the edge of the support towel 10 during the manufacturing process, which can effectively define and fix the edge of the support towel 10.

[0062] In this embodiment, to ensure accurate fecal collection during use, a downwardly recessed collection cavity is formed between the retaining edge 101 and the retaining cloth 10. This collection cavity concentrates feces during excretion, reducing the risk of excrement slipping off the retaining cloth 10 and providing a more stable and concentrated area for subsequent sample collection. This ensures the reliability and stability of fecal collection and provides a reliable guarantee for subsequent sampling operations, achieving convenience, safety, and stable sample quality during the sampling process.

[0063] Preferably, the support towel 10 is an elastic structure, while the connecting piece 20 is a non-elastic structure. The support towel 10 is made of an elastic material, which allows it to have a certain stretch distance along its length, enabling it to adapt to toilets 30 of different diameters. Furthermore, it allows it to sink under the pressure of patient excrement and provides elastic cushioning, preventing damage at the tear H12 caused by gravitational impact, thus ensuring its reliability. The connecting piece 20, on the other hand, is made of a non-elastic material. This non-elastic structure ensures that the connecting piece 20, after being fixed to the edge of the toilet 30, maintains a stable and non-deformable shape. This allows the adhesive piece 201 to maintain a fixed geometric shape when subjected to external forces or the patient's weight, thereby providing stable support and fixation for the entire device.

[0064] Preferably, the water-soluble material is selected from one or more of polyvinyl alcohol, polyethylene glycol, and carboxymethyl cellulose. On the one hand, the support cloth 10 using polyvinyl alcohol not only possesses high tensile strength and toughness but also excellent water solubility, and its dissolution rate can be further optimized by adjusting the molecular weight and ratio. In addition, in some embodiments, a certain amount of polyethylene glycol can be added to polyvinyl alcohol. This mixed material, while ensuring the toughness of the support structure, can improve its overall flexibility and dissolution uniformity, allowing the support cloth 10 to dissolve quickly and thoroughly after flushing, reducing residual contaminants. On the other hand, carboxymethyl cellulose itself has high hygroscopicity, which can effectively absorb some of the moisture in feces, thereby protecting the support cloth 10 from rapid dissolution in the initial contact with feces. By combining it with polyvinyl alcohol or polyethylene glycol, the complementary advantages of different materials in water solubility, mechanical strength, and hygroscopicity can be utilized to form a composite structure that can provide stable support and dissolve quickly in water.

[0065] Preferably, the connecting piece 20 is made of non-woven fabric. Because the non-woven fabric connecting piece 20 has good tensile strength and low elongation, it will not deform significantly even when subjected to external force, thus ensuring that both ends of the supporting towel 10 remain in the predetermined position and guaranteeing its reliable fixation.

[0066] In one embodiment of this utility model, the adhesive component 201 is an adhesive tape covered with a release film, the adhesive tape being adapted to the shape of the toilet rim. The release film not only protects the adhesiveness of the tape but also makes it convenient for users to easily attach the tape to the toilet rim by simply peeling off the release film, making it simple and convenient to use.
