Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical examination auxiliary tools, in particular to a stool specimen sampling package for detecting Clostridium difficile infection. Background Art
[0002] Clostridium difficile infection (CDI) is one of the main causes of nosocomial infectious diarrhea, especially in patients who have been using broad-spectrum antibiotics or immunosuppressive therapy for a long time. Its high incidence, recurrence rate and potential lethality pose a severe challenge to public health. Rapid and accurate pathogen detection is a key link in early diagnosis, timely intervention and blocking transmission, and the detection of Clostridium difficile toxins or genes in stool samples is regarded as the "gold standard" for diagnosing CDI.
[0003] Existing stool specimen sampling kits for Clostridium difficile testing usually consist of disposable collection swabs, stool sampling boxes, preservative fluid and labels. When using, first check the integrity of the sampling package, whether the components are complete and whether they are within the shelf life, wash your hands, and after defecation, open the sampling package and use a disposable collection swab to collect an appropriate amount of samples from different parts of the stool, or use a sampling spoon to collect from multiple points on the surface, middle and edge of the stool; then open the stool sampling box containing the preservative fluid, put in the swab or sampling spoon for collecting stool, and ensure that the stool is completely immersed in the preservative fluid. Finally, cover the sampling box, accurately fill in personal information on the label, and send it for inspection in time as required. Of course, there are some sampling kits on the market that will be equipped with plastic receiving trays for patients to defecate into the plastic receiving trays, so as to reduce the probability of contamination of stool samples.
[0004] However, traditional sampling tools rely on a plastic receiving tray that is placed directly on the toilet or on the ground, but are not equipped with an adaptive fixing structure. Users need to adjust the position of the receiving tray by themselves during defecation, and the surface of the plastic receiving tray is smooth and lacks a limit design. When placed on the toilet, it will protrude from the toilet seat, which will make its position on the toilet unstable and it is very easy to move or even fall during defecation, which not only affects the accuracy of sampling, but also causes bathroom environmental pollution. Moreover, its protrusion from the toilet seat will prevent patients from sitting directly on the toilet, which will undoubtedly increase the difficulty of defecation and sampling for patients (especially elderly patients). This design defect directly restricts the feasibility of patient self-sampling and the reliability of test results. Summary of the invention

DETAILED DESCRIPTION
[0043] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0044] The present invention focuses on solving the defects of traditional stool specimen sampling kits for detecting Clostridium difficile infection, and carefully designs a sampling kit that combines convenience, accuracy and environmental protection. The various components work together to greatly improve the sampling experience and detection reliability.
[0045] The following describes an embodiment of the present invention based on its overall structure.
[0046] like Figure 1 - Fig. 9 As shown, the stool specimen sampling kit for detecting Clostridium difficile infection of the present invention comprises a main body 1 which is composed of a storage bag 2, a container 3 and a sampling box 4;
[0047] Among them, the storage bag 2 is like a convenient storage container, which is composed of a first bag body 21, a second bag body 22 and a pull tab 23; the first bag body 21 and the second bag body 22 are symmetrically connected, and the adhesive on the outer wall makes them fit tightly when not in use, thereby protecting the internal components; the pull tab 23 is the key to opening the storage bag 2. By pulling the pull tab 23, the storage bag 2 can be easily opened, and the container 3 and the sampling box 4 can be taken out, which is convenient for users to operate, and the two sets of pull tabs 23 are staggered with each other, which is convenient for users to open the first bag body 21 and the second bag body 22.
[0048] The receiver 3 in the present invention undertakes the important task of collecting feces during the sampling process, and its core components include a receiving bag 31, a force transmission belt 32, a drawstring 33 and a connector 34;
[0049] The receiving bag 31 is designed to be tilted toward the bottom after being opened. This unique shape allows the feces to slide naturally and collect at the bottom during the collection process, which is convenient for subsequent sampling.
[0050] At the same time, the drawstring 33, the force transmission belt 32 and the receiving bag 31 in the receiving container 3 are all made of soluble materials; while ensuring that the drawstring 33, the force transmission belt 32 and the receiving bag 31 have certain flexibility and strength, they are not easily damaged during use; after the sampling is completed, they can be directly thrown into the toilet and flushed away, and then dissolved in the pipe to avoid clogging the toilet, and no additional treatment is required, effectively preventing cross infection;
[0051] Specifically, the receiving bag 31 adopts a commercially available medical-grade PVA water-soluble bag (such as a Medline sample collection bag), which has a short-term impermeability and can be flushed into the toilet for rapid dissolution after sampling. Of course, in other examples, the receiving bag 31 can also use a commercially available flushable cellulose-based sanitary pad (such as a Dynarex sanitary pad), which has a temporary waterproof coating on the surface and can be directly flushed into the toilet for decomposition after sampling. Of course, the receiving bag 31 can also use a starch-based degradable packaging film (such as a BioBag specimen bag), which has a short-term impermeability function and can be safely flushed into the toilet for dissolution after use. The The anti-seepage time is 8-15 minutes, and the dissolution time is within 30 minutes. Both have short-term anti-seepage function. After use, they can be safely flushed into the toilet for dissolution. At the same time, the materials used for the drawstring 33 and the power transmission belt 32 are the same, so that the drawstring 33 and the power transmission belt 32 have the same effect. In the present invention, the materials used for the receiving bag 31, the drawstring 33 and the power transmission belt 32 are not directly and completely limited. In the actual processing process, the corresponding materials can be selected according to actual needs. As long as it is guaranteed that it will not be easily damaged during use and can smoothly receive feces, it can be directly flushed into the toilet for dissolution after use.
[0052] Exemplarily, the longitudinal section of the force transmission belt 32 is trapezoidal, and its width is the same as that of the receiving bag 31. This design enables the force transmission belt 32 to evenly transmit the pulling force to the receiving bag 31 when the drawstring 33 is pulled, thereby helping the receiving bag 31 to be smoothly unfolded. At the same time, a handle groove 35 away from the connector 34 is provided at the end of the drawstring 33 to facilitate the user to grasp and apply force, making it easier and more convenient to unfold the receiving bag 31 or to subsequently disassemble the receiving bag 31.
[0053] The connector 34 in the present invention is composed of a bottom plate 36, an outer plate 37, a triangular plate 39 and an inner support plate 38, and the material is selected from low-cost high-strength engineering plastics, such as modified polypropylene PP; this material has a certain flexibility while ensuring strength and wear resistance, and can be tightly clamped on the inner and outer sides of the toilet seat; during installation, first lift the toilet seat, clamp the outer plate 37 and the inner support plate 38 on the bottom of the toilet seat, so that the bottom plate 36 fits the bottom of the toilet seat, and the outer plate 37 and the inner support plate 38 are respectively attached to the inner wall and outer wall of the toilet seat, and then the connector 34 on the other side is also installed. After putting down the toilet seat, the toilet seat squeezes the connector 34 to ensure a stable connection, so that the receiver 3 will not shift or fall during the sampling process. At the same time, the triangular plate 39 will support the inner support plate 38 and the bottom plate 36 to reduce the probability of deformation;
[0054] Exemplarily, the sampling box 4 in the present invention is responsible for storing the collected feces sample, and is composed of a box body 41, a box cover 42, a sampling tube 43 and an air-evacuating rubber ball 44;
[0055] The box body 41 and the box cover 42 are connected by threads, which is not only convenient for opening and closing, but also ensures good sealing to prevent sample leakage and external contamination;
[0056] The scale lines on the outer wall of the box body 41 facilitate the user to observe the sample volume. The box body 41 is filled with a preservation solution, and the top of the preservation solution is higher than the top of the bottom opening of the sampling tube 43, which can ensure that the collected stool sample is fully mixed with the preservation solution and effectively preserve the sample, thereby providing a guarantee for the accuracy of subsequent testing;
[0057] The sampling tube 43 in the sampling box 4 has an L-shaped cross section, and the bottom opening corners are designed with bevels. The L-shaped design facilitates flexible operation when collecting fecal samples, and the bevel opening can be inserted into feces more easily, reducing damage to the sample and improving sampling efficiency.
[0058] At the same time, the elastic member in the air-evacuating rubber ball 44 is composed of a longitudinal ring 45 and a transverse ring 46 connected to each other, and the material is a blend of natural rubber and synthetic rubber with low cost; this material has good elasticity and can quickly return to its original shape after multiple squeezing, providing stable suction for the sampling tube 43;
[0059] When collecting thin feces, first squeeze the air-evacuating rubber ball 44 to expel the air, then insert the sampling tube 43 into the feces, loosen the air-evacuating rubber ball 44, and under the action of the elastic member, the sampling tube 43 sucks the thin feces; the through hole at the center of the box cover 42 connects the sampling tube 43 and the air-evacuating rubber ball 44, and the diameter of the through hole is smaller than the diameter of the longitudinal ring 45, which effectively prevents the elastic member from falling out and ensures the normal operation of the air-evacuating rubber ball 44.
[0060] The working principle of the present invention is as follows: when it is necessary to sample a stool specimen, the user first pulls two mutually staggered pull tabs 23, so that the two pull tabs 23 drive the corresponding first bag body 21 and the second bag body 22 to start to separate, and at this time, the receiver 3 and the sampling box 4 in the storage bag 2 will leak out, and the next step of operation can be continued;
[0061] If the user is an elderly person who needs to use a toilet, first pull the handle grooves 35 on both sides of the receiver 3 to both sides, so that the drawstring 33 can unfold the receiving bag 31 through the force transmission belt 32, and then the connector 34 on the side wall of the drawstring 33 can be connected to the toilet seat, until the two connectors 34 are connected to the toilet seat, and the receiving bag 31 is located in the toilet seat, and the user can start to defecate. During the defecation process, the patient's feces will fall into the receiving bag 31, and the receiving bag 31 will collect the feces, and then the user can open the sampling box 4 to make the box body 4 1 is separated from the box cover 42, at which time the sampling tube 43 will leak out, and then the user presses or squeezes the vacuum rubber ball 44 to exhaust the air in the vacuum rubber ball 44, at which time the longitudinal ring 45 or the transverse ring 46 will be compressed and begin to deform, and then the user inserts the bottom opening of the sampling tube 43 into the feces for sampling. After the sampling is completed, the sampling tube 43 is put back into the box body 41 to mix the feces with the Clostridium difficile preservation solution built into the box body 41. At this time, the box body 41 and the box cover 42 are re-tightened to complete the sampling, which is convenient for the subsequent Clostridium difficile infection detection;
[0062] Finally, the user presses the toilet seat with one hand and pulls the handle groove 35 with the other hand to tear off the drawstring 33 from the connector 34, and then separates the drawstring 33 on the other side from the connector 34. At this time, the receiver 3 will fall into the toilet. Since the receiving bag 31, the force transmission belt 32 and the drawstring 33 are all made of soluble materials, they will gradually dissolve after falling into the toilet, thereby preventing the toilet from being blocked after being thrown into the toilet. At the same time, it has the advantages of being easy to handle, being able to be directly flushed away, and avoiding cross infection or the need for additional treatment.
[0063] In the process of connecting the connector 34 to the toilet seat, the toilet seat needs to be lifted first, and then the outer plate 37 and the inner support plate 38 are clamped on the bottom of the toilet seat until the bottom plate 36 is in contact with the bottom of the toilet seat. At this time, the outer wall of one side of the outer plate 37 will be in contact with the inner wall of the toilet seat, and the outer wall of one side of the inner support plate 38 will be in contact with the outer wall of the toilet seat, so as to ensure that the outer plate 37 and the inner support plate 38 can be smoothly connected to the toilet seat. Then, the connector 34 on the other side is connected to the toilet seat in the same way, and finally the toilet seat is reset. The top and bottom of the bottom plate 36 will be in contact with the bottom and The top surface of the toilet is close to each other, so that the toilet seat will squeeze the connector 34, so as to ensure the stability of the connection between the connector 34 and the toilet seat. When feces enter the receiving bag 31, the outer plate 37 and the inner support plate 38 will be restricted by the toilet seat, so that the connector 34 cannot be separated from the toilet seat. When the user stands up and leaves the toilet seat, the connectors 34 on both sides will be restricted by the toilet seat. Even if the toilet seat loses the gravity given by the user, the receiving bag 31 that receives the feces cannot separate the connector 34 from the toilet seat, ensuring that the user can smoothly collect feces samples later.
[0064] If the user is in a place where there is only a squat toilet, the user can open the storage bag 2 and fully unfold it, and then lay the unfolded first bag body 21 and second bag body 22 on the bathroom floor or squat toilet, so as to avoid the impact on the environment during the sampling process. Then, the user pulls open the receiving bag 31, and the user can directly put the receiving bag 31 on the user's buttocks by pulling the drawstrings 33 on both sides, or place the receiving bag 31 on the unfolded storage bag 2. The actual use can be determined according to the user himself, and then the receiving bag 31 containing feces is placed on the storage bag 2 for sampling;
[0065] During the sampling process, if the feces discharged by the user are normal feces, the user aligns the end opening position of the sampling tube 43 with the feces and then directly inserts it into the feces, and then gently pries up the end of the sampling tube 43 inserted into the feces. At this time, the feces will enter the end of the sampling tube 43, so that normal feces can be sampled smoothly. Because the diameter of the sampling tube 43 is greater than the thickness of the existing sampling spoon, it can effectively avoid the problems of the sampling spoon breaking during the feces sampling process, the sampling spoon being too small and requiring multiple samplings, etc.
[0066] If the feces discharged by the user are thin feces, the end opening position of the sampling tube 43 is aligned with the feces and then directly inserted into the feces. Because the air-evacuating rubber ball 44 has been in a compressed state before, the user can release the squeezing of the air-evacuating rubber ball 44 at this time. At this time, the air-evacuating rubber ball 44 will begin to reset under the action of its own characteristics and the longitudinal ring 45 or the transverse ring 46. Because the end opening position of the sampling tube 43 is located in the thin feces, the sampling tube 43 will draw the thin feces into the interior under the action of the air-evacuating rubber ball 44 at this time, and then the sampling tube 43 is rotated by rotating the box cover 42 to a state where its opening is tilted upward to prevent the thin feces from accidentally flowing out of the sampling tube 43. At this time, the sampling of the thin feces is completed, so that the sampling tube 43 can smoothly sample the thin feces, effectively improving the practicality of the sampling package.
[0067] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
