Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a stool sampler that is easy to use. Background Technology

[0002] Stool examination is a commonly used testing method in the medical and health industry. This examination can provide a relatively direct understanding of some pathogenic microorganisms and pathological phenomena in the gastrointestinal tract, and indirectly determine the functional status of the digestive tract, pancreas, liver and gallbladder. Therefore, routine stool examination, along with routine blood and urine examinations, is collectively referred to as the three major routine examinations.

[0003] Currently, stool sampling for testing involves using a small plastic cup (or test tube) and a sampling spoon (or sampling rod). Because the opening of the plastic cup (or test tube) is small, the sampler must hold the cup in their hand to catch the stool during defecation if they want to collect it before it falls into the toilet bowl. Since the anus is not visible to the naked eye, and the opening is small, it's difficult for the sampler to control the amount entering the cup, and they cannot guarantee that the stool won't stick to the rim or outside the cup, nor can they prevent stool from contaminating the patient's hands. If the sampler waits until the stool falls into the toilet bowl before taking the sample, firstly, residual excrement from other people in the toilet bowl or the disinfectant used to clean the toilet can easily contaminate the sample, affecting the accuracy of the test results. Secondly, the process of close-range contact with the stool can also cause discomfort.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0005] The purpose of this invention is to provide a stool sampler that is easy to use.

[0006] The present invention is implemented as follows: a stool sampler that is easy to sample includes a receiving tube, a receiving bag, a sampling part and a connecting tube.

[0007] The receiving tube is a container with one open end, and the open end of the receiving tube is detachably connected to the connecting tube.

[0008] The connecting tube is a hollow pipe with openings at both ends. One end of the connecting tube is detachably connected to the open end of the receiving tube, and the other end is connected to one side of the receiving bag.

[0009] The container bag is a bag-shaped container with one end open. The container bag is also provided with a sampling hole. The other end of the connecting tube is connected to the sampling hole, and the connecting tube is connected to the container bag through the sampling hole.

[0010] The sampling unit includes a long-handled spoon, which is connected to the receiving bag. The spoon head is inside the receiving bag, while the other end is outside the receiving bag.

[0011] The beneficial effects of adopting the above scheme are as follows: The fecal sampler in this scheme includes a container tube for storing fecal samples, a container bag for collecting fecal samples during defecation, and a sampling part for sampling fecal samples from the container bag into the container tube, and also includes a connecting tube for connecting the container bag and the container tube.

[0012] In this method, a container bag is used to collect the excreted feces during defecation. Because the opening of the container bag is relatively large, it is convenient for the sampler to hold the bag and wrap it around the anus to catch the excreted feces without contaminating their hands, thus improving the sampler's adaptability.

[0013] To reduce discomfort for the sampler during the sampling process after the stool enters the receiving bag, this design features a long-handled spoon with one end inside the receiving bag and the other end outside. The long-handled spoon extends through the receiving bag, with the spoon head inside. A connecting tube is connected to the receiving bag via a sampling hole. The sampler can then close the opening of the receiving bag, use the handle of the long-handled spoon (located outside the bag) to scoop up the stool from inside the bag, pass it through the sampling hole and connecting tube to the bottom of the receiving tube, and then return the long-handled spoon to the receiving bag. For ease of sampling, the length of the long-handled spoon inside the receiving bag is no less than the combined length of the connecting tube and the receiving tube.

[0014] To facilitate the transfer of the receiving tube after sampling, a connecting tube is installed between the receiving tube and the receiving bag, and the receiving tube and the connecting tube are detachably connected. After sampling is completed, the receiving tube and the connecting tube can be separated, the receiving tube can be sent to the testing area, and the remaining part can be thrown into the trash can.

[0015] The connection between the connecting tube and the sampling hole can be achieved using common methods in existing technologies for fixing plastic tubes and plastic bags, such as adhesive bonding, high-temperature bonding, etc.

[0016] Furthermore, an inner tube is provided inside the connecting pipe. The inner tube is a hollow pipe. One end of the inner tube is fixedly connected to the inner wall of the connecting pipe, and the other end of the inner tube extends to the outside of the opening of the connecting pipe.

[0017] The receiving tube is a flat-bottomed receiving tube.

[0018] The beneficial effects of adopting the above scheme are as follows: In order to avoid the feces contaminating the opening of the receiving tube during the sampling process, making it inconvenient for personnel to handle the feces sample later, or causing discomfort to personnel during transportation and waiting for testing, this scheme also sets up an inner tube inside the connecting tube. The inner tube is located inside the connecting tube, with one end fixedly connected to the inner wall of the connecting tube, and the other end extending out of the connecting tube from the opening of the connecting tube. The part extending out of the connecting tube will pass through the opening of the receiving tube and enter the receiving tube after the receiving tube is connected to the connecting tube. In this way, during the sampling process, the spoon head of the long-handled spoon will pass through the inner tube and then enter the receiving tube. Because the inner tube has already passed through the opening of the receiving tube and entered the receiving tube, the feces in the spoon head cannot come into contact with the opening of the receiving tube during the sampling process, so no contamination will be caused.

[0019] In this solution, to facilitate the placement of the receiving tube when the sampler washes their hands after sampling and when the sample is awaiting testing, the receiving tube is designed to be a flat-bottomed receiving tube, so that the receiving tube can be placed directly on the platform.

[0020] Furthermore, the diameter of the opening of the container bag is [diameter missing], and the container bag also includes a sealing device for closing the opening of the container bag.

[0021] The beneficial effects of adopting the above scheme are as follows: considering the convenience of the sampler holding the container bag to cover the anus to collect the stool during defecation, the opening diameter of the container bag is 25-35 cm.

[0022] To further reduce discomfort during the sampling process, this solution includes a sealing device at the opening of the container bag. This allows the sampler to close the opening of the container bag after defecating before taking the sample.

[0023] Furthermore, the sealing device is a drawstring sealing device.

[0024] The beneficial effects of adopting the above solution are as follows: the sealing device in this solution is a drawstring sealing device, which is a commonly used drawstring sealing device in the prior art. It includes a drawstring channel set at the bag opening and two drawstrings passing through the drawstring channel. The bag opening can be closed by pulling the drawstrings in opposite directions.

[0025] Furthermore, the outer periphery of the containment bag is provided with a skirt, which has an adhesive function.

[0026] The beneficial effects of adopting the above solution are as follows: This solution features a skirt around the outer perimeter of the receptacle bag. The skirt is a ring-shaped strip around the outer edge of the bag, with one side fixedly connected to the bag and the other side free. One or both sides of the skirt have adhesive properties, allowing the sampler to easily place the skirt against their buttocks when using a squat toilet for sampling. This ensures that the sampler can easily deposit stool into the receptacle bag even when the anus is not visible, preventing contamination of the bag opening and hands. Before use, a release liner matching the skirt size is attached to the skirt; this liner can be removed to use the adhesive function.

[0027] The skirt in this solution is also suitable for sampling when the sampler defecates in the toilet. Before sampling, the sampler can first peel off the release paper and then stick the skirt to the edge of the toilet, so that the sampler can collect the stool without holding the container bag.

[0028] The hem of the skirt should be centered on the opening of the storage bag, and the hem should ideally be positioned closer to the opening of the storage bag.

[0029] Furthermore, the skirt hem is made of electrostatic film.

[0030] The beneficial effects of adopting the above scheme are as follows: In this scheme, in order to make it easier for the sampler's buttocks or toilet to separate after defecation without leaving any trace, the skirt material is selected as electrostatic film, such as PE electrostatic film, PVC electrostatic film and PU film.

[0031] Furthermore, the sampling unit also includes a sampler sealing cover, which includes an inner cover and an outer cover. The outer cover is threaded to the connecting pipe, and the inner cover is a circular protrusion on the inner wall of the sampler sealing cover. The other end of the receiving bag is connected to the outer wall of the inner cover. A through hole 2 is provided in the inner cover, and a long-handled spoon passes through the through hole 2 and is connected to the inner cover.

[0032] The connecting pipe has external threads at both ends, and the open end of the receiving pipe and the outer cover are respectively provided with internal threads that match the external threads of the connecting pipe.

[0033] The beneficial effects of adopting the above scheme are as follows: In this scheme, to ensure that the sampler is a single, convenient, and easily stored and transportable device before use, the sampling section also includes a sampler sealing cover. The sampler sealing cover includes an inner cover and an outer cover concentrically arranged. The outer cover is threaded to a connecting pipe, and the outer wall of the inner cover is fixedly connected to the receiving bag by adhesive or heat pressing, so that the receiving bag encloses the inner cover. A through hole is provided on the top of the inner cover, through which the handle of the long-handled spoon passes, so that the tip of the long-handled spoon is inside the receiving bag, while the other end is simultaneously outside both the sampler sealing cover and the receiving bag. The long-handled spoon and the inner cover can be fixedly connected, i.e., integrally formed, or the inner cover can be threaded to one end of the handle.

[0034] In this design, the connection point between the connecting tube and the receiving bag is located between the external thread connecting the connecting tube to the sampler's sealing cap and the opening at the connection end of the connecting tube and the sampler's sealing cap.

[0035] Before use, the convenient stool sampler of this solution is made by threading the receiving tube and the connecting tube together. The two ends of the receiving bag are fixedly connected to the inner cover of the connecting tube and the sampler's sealing cap, respectively. The middle part of the receiving bag is inserted into the connecting tube. Then, the sampler's sealing cap is threaded to the connecting tube, thus forming a complete sampler that is convenient for storage and transportation.

[0036] Furthermore, the receiving tube, connecting tube, and receiving bag are all made of transparent material.

[0037] The beneficial effects of adopting the above scheme are as follows: the materials of the container tube, connecting tube and container bag in this scheme are all transparent, so that the sampler can observe the sampling operation and the sample volume in real time.

[0038] Furthermore, the container bag is made of polyethylene and is folded before use; the container tube and connecting tube are made of plastic.

[0039] The beneficial effects of adopting the above solution are as follows: In this solution, in order to make the container bag easy to compress, easy to use and reduce costs, the container bag is made of polyethylene, a common material.

[0040] Considering ease of use and cost, the receiving tube and connecting tube in this design are made of plastic. The sampler's sealing cap and long-handled spoon can also be made of plastic.

[0041] In this solution, the container bag is folded before use. The folded state here is similar to the folded (compressed) state of a shower cap or food storage sleeve in the prior art. That is, the air inside the container bag is expelled by squeezing or by using a vacuum tool to fold (compress) the container bag so that it can be inserted into the connecting tube.

[0042] Furthermore, it also includes a cap for sealing the receiving tube, the cap being hinged to the receiving tube.

[0043] The beneficial effects of adopting the above solution are as follows: In this solution, to reduce discomfort for personnel after complete sampling and to avoid sample contamination before testing, a cap for sealing the receiving tube is also provided, allowing the cap to be placed on the receiving tube after sampling. The cap is hinged to the receiving tube, so that when the receiving tube is connected to the connecting tube, the cap can be hung beside the receiving tube via the hinge. The hinge can be made of a flexible plastic component.

[0044] Based on the above solution, the beneficial effects of this utility model embodiment are:

[0045] 1. The present invention provides a convenient fecal sampler, comprising a receiving tube, a connecting tube, a receiving bag, and a sampling part. By setting up a receiving bag, it is convenient for the sampler to collect the feces smoothly during defecation, and then use the sampling part to scoop the feces into the receiving tube, avoiding feces contamination of the hands and receiving tube during the collection process, and the sampler does not need to take potentially contaminated samples from the toilet bowl.

[0046] 2. The stool sampler provided by this utility model has a sealing device in its container bag, which avoids the discomfort of the sampler facing the stool directly during the sampling process.

[0047] 3. The fecal sampler provided by this utility model has an inner tube in the connecting tube, which can further prevent fecal contamination of the receiving tube opening during the sampling process.

[0048] 4. The fecal sampler provided by this utility model has a skirt with adhesive function on the outer periphery of the receiving bag, which makes it more convenient for the sampler to collect the feces.

[0049] 5. The present invention provides a stool sampler that is easy to collect, has a simple structure, is easy to use, has low cost, and is easy to store and transport. Attached Figure Description
