Abstract
Description
Technical Field
[0001] This invention relates to the field of medical testing technology, specifically to a sampling bottle for fecal sampling. Background Technology
[0002] In fields such as medical testing, clinical diagnosis, and environmental health monitoring, fecal samples are important testing targets, and the standardization, sealing, and uniformity of their sampling directly affect the accuracy of subsequent test results.
[0003] Currently, traditional fecal sampling methods often involve using simple tools such as cotton swabs and small spoons to directly collect samples, which are then transferred to a container containing buffer or treatment solution. This process has many drawbacks. Traditional sampling tools lack an effective sealing structure, and during the transfer of samples to the container after sampling, feces are easily spilled due to unstable handling and sample shaking. In addition, the sampling drive structure is constantly soaked in feces, increasing the failure rate. Furthermore, it is difficult to control the sampling volume as needed, such as for micro-samples, which makes it difficult to meet the quantitative testing needs of laboratories. Summary of the Invention
[0004] The purpose of this invention is to provide a sampling bottle for fecal sampling to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a sampling bottle for fecal sampling, comprising a sampling bottle body and a pipette, wherein a sealing cap is threadedly installed inside the sampling bottle body, and an internal column is provided inside the sealing cap, wherein an auxiliary component for assisting sampling is installed inside the internal column, and a sampling component for sampling and sealing feces is installed at the bottom of the auxiliary component, wherein the sampling component comprises a connecting rod, a sampling plate and an end plate, and a sampling plate is installed at the end of the connecting rod, and end plates are provided at both the upper and lower ends of the sampling plate, and the pipette is located in the middle of the sealing cap.
[0006] Furthermore, the outer surface of the sealed bottle cap is circumferentially distributed with striped columns, and the sealed bottle cap and the striped columns are an integral structure.
[0007] Furthermore, a rubber cap is fitted onto the top outer surface of the sealed bottle cap, and the rubber cap has an internal groove.
[0008] Furthermore, a plug is fixedly installed in the middle of the cap, and the plug is located at the top of the straw.
[0009] Furthermore, the sampling plate and the end plate are an integrated structure, and the sampling plate and the end plate form a hollow fan-shaped structure.
[0010] Furthermore, the auxiliary component includes a fixing block, a connecting plate, a connecting shaft, and a connecting spring. The outer surface of the fixing block is provided with a connecting spring, a connecting rod is installed at the end of the connecting spring, and a connecting shaft is rotatably installed at the top of the connecting rod. Both ends of the connecting shaft are provided with connecting plates.
[0011] Furthermore, the auxiliary component has a threaded post at its top, and the threaded post is threadedly installed inside the built-in post.
[0012] Furthermore, the sampling components are distributed in a one-to-one correspondence with the auxiliary components, and there are four sampling components.
[0013] This invention provides a sampling bottle for fecal sampling, which has the following beneficial effects: 1. This invention uses four sets of hollow fan-shaped sampling plates and end plates to form a sampling assembly. With the linkage design of auxiliary components and threaded columns, the sampling plates and end plates can be driven to close together by rotating the threaded columns during sampling, achieving a sealed enclosure of the fecal sample. During the transfer process, the sample is always in a closed space, effectively avoiding sample spillage caused by hand shaking. At the same time, it reduces the direct contact between the sample and the external environment and operators, greatly reducing the risk of sample contamination and cross-infection, and improving the safety and standardization of sampling operations. In addition, the opening and closing angle of the sampling plates and end plates is controllable, which facilitates the required sampling.
[0014] 2. In the sample transfer stage, the reverse rotation of the threaded column moves the sampling plate and end plate away from each other, allowing the fecal sample to slowly fall into the buffer solution of the sampling bottle. The sampling component rotates as it moves away, driving the buffer solution to flow and ensuring thorough mixing of the fecal sample and the processing solution. This avoids uneven sample composition distribution. Simultaneously, the slow contact design prevents sample clumping, further improving mixing and providing a uniformly mixed processing solution for subsequent testing, ensuring reliable test results. The device is equipped with a pipette, a cap, and a plug for sealing, ensuring the bottle is airtight when not in use. Before testing, simply open the cap (pipette sealing structure), tilt the bottle, and use the pipette to accurately obtain the fecal processing solution suitable for the reagent plate's testing requirements. This solution is then directly added to the reagent plate's detection well to complete sample preparation. Attached Figure Description

Detailed Implementation
[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a sampling bottle for fecal sampling includes a sampling bottle body 1, a sealing cap 2, a rubber cap 3, an internal column 4, a straw 5, an internal groove 6, a plug 7, a sampling component 8, a connecting rod 801, a sampling plate 802, an end plate 803, a threaded column 9, an auxiliary component 10, a fixing block 1001, a connecting plate 1002, a connecting shaft 1003, a connecting spring 1004, and a striped column 11. The sealing cap 2 is threaded inside the sampling bottle body 1, and the internal column 4 is provided inside the sealing cap 2. The auxiliary component 10 for assisting sampling is installed inside the internal column 4, and the sampling component 8 for sampling and sealing feces is installed at the bottom of the auxiliary component 10. The sampling components 8 are distributed one-to-one with the auxiliary component 10, and the sampling components 8 are provided with... Four mechanisms are in place. When the threaded post 9 in the built-in post 4 is rotated, the threaded post 9 moves upward, and the built-in post 4 applies a force to the connecting rod 801 from the outside. This causes the connecting rod 801 to rotate due to the action of the connecting plate 1002 and the connecting shaft 1003, resulting in a tight fit between the sampling plate 802 and the end plate 803 at the end of the connecting rod 801, thus fixing the sample. When the sample needs to be removed from the space formed by the sampling plate 802 and the end plate 803, the threaded post 9 in the built-in post 4 can be rotated in the opposite direction. This removes the force applied to the connecting rod 801 from the outside, causing the connecting rod 801 to move outward due to the design of the connecting spring 1004. Consequently, the four sets of sampling plates 802 and end plates 803 move away from each other, removing the feces inside. The sample is transferred to the inside of the sampling bottle 1. The top of the auxiliary component 10 is provided with a threaded post 9, which is threaded into the inside of the built-in post 4. The auxiliary component 10 includes a fixing block 1001, a connecting plate 1002, a connecting shaft 1003, and a connecting spring 1004. The outer surface of the fixing block 1001 is provided with the connecting spring 1004, and a connecting rod 801 is installed at the end of the connecting spring 1004. The top of the connecting rod 801 is rotatably mounted with the connecting shaft 1003, and both ends of the connecting shaft 1003 are provided with connecting plates 1002. The sampling component 8 includes a connecting rod 801, a sampling plate 802, and an end plate 803. The end of the connecting rod 801 is equipped with the sampling plate 802. The sampling plate 802 and the end plate 803 are an integrated structure. The sampling plate 802 and end plate 803 form a hollow fan-shaped structure. End plates 803 are provided at both the upper and lower ends of the sampling plate 802. The straw 5 is located in the middle of the sealed cap 2. By rotating the sealed cap 2, it can be separated from the threaded part of the sampling bottle 1. When sampling feces, the user can align the sampling plate 802 and end plate 803 with the feces area. Then, the user rotates the threaded post 9 in the built-in post 4, causing the threaded post 9 to move the entire sampling assembly 8 upwards. Subsequently, the four sets of sampling plates 802 and end plates 803 approach each other and seal, sealing the feces for easy and stable transfer into the sampling bottle 1, preventing spillage due to unstable handling. After placing the sealed feces into the sampling bottle 1, the threaded post 9 is rotated in the opposite direction.This will cause the entire sampling assembly 8 to move downwards, thus moving the sampling plate 802 and end plate 803 away from each other. The feces will be transferred to the sampling bottle 1, where it will be thoroughly mixed with the pre-set buffer solution or the treatment solution added according to the testing requirements, forming a homogeneous feces treatment solution. As the sampling plate 802 and end plate 803 move away from each other, the movement ensures that the feces slowly come into contact with the buffer solution in the sampling bottle 1. Simultaneously, the entire sampling assembly 8 will rotate within the buffer solution, further ensuring uniform distribution of sample components and improving the accuracy of subsequent testing. Open the cap 3 on the pipette 5, hold the sampling bottle 1 at a certain angle, and use the pipette 5's suction function to accurately sample the mixed feces treatment solution in the bottle 1. Then, slowly drip the sampled treatment solution into the corresponding reagent plate detection well, completing the sample preparation before testing. Subsequent routine reagent plate testing operations can then be performed.
[0019] like Figure 3 As shown, the outer surface of the sealed bottle cap 2 is circumferentially distributed with striped columns 11, and the sealed bottle cap 2 and the striped columns 11 are integrated into one structure. The design of the striped columns 11 can provide frictional resistance when the user holds the sealed bottle cap 2, assisting the user in rotating the sealed bottle cap 2. A rubber cap 3 is snapped onto the top outer surface of the sealed bottle cap 2, and the inside of the rubber cap 3 has an internal groove 6. A plug 7 is fixedly installed in the middle of the rubber cap 3, and the plug 7 is located at the top of the straw 5. Through the design of the rubber cap 3, the internal groove 6 and the plug 7, when the rubber cap 3 is snapped onto the sealed bottle cap 2, the plug 7 can be used to seal the end of the straw 5, ensuring the sealing of the entire sampling bottle 1.
[0020] In summary, the sampling bottle used for this fecal sampling was first based on... Figures 1-5In the structure shown, during initial use, the sampling bottle 1 and the sealing cap 2 are tightly connected by threads to ensure overall sealing. The cap 3 is snapped onto the top outer surface of the sealing cap 2, and the plug 7 inside is located precisely at the top of the pipette 5. The plug 7 seals the end of the pipette 5, further ensuring the sealing of the sampling bottle 1 and preventing leakage of the internal buffer solution or treatment solution. At this time, the four sampling plates 802 and the end plate 803 of the sampling assembly 8 are in a state of mutual distance, facilitating subsequent sampling operations. The user can use the annular striped columns 11 (the striped columns and the sealing cap are an integral structure) on the outer surface of the sealing cap 2 to provide sufficient frictional resistance, and rotate the sealing cap 2 to make it fit against the cap. After the sampling bottle 1 is unscrewed, the sampling plate 802 and end plate 803 at the end of the connecting rod 801 in the sampling assembly 8 are aligned with the target fecal area to complete the sampling positioning. The user rotates the threaded column 9 inside the built-in column 4, which drives the auxiliary assembly 10 and the sampling assembly 8 connected to it to move upward as a whole. During this process, the built-in column 4 applies a force to the connecting rod 801 of the sampling assembly 8 from the outside. The connecting rod 801 is deflected by the rotational cooperation between the connecting plate 1002 and the connecting shaft 1003 in the auxiliary assembly 10, so that the four sets of sampling plates 802 and end plates 803 come closer to each other and fit tightly together (the sampling plate and the end plate are an integrated structure), forming a hollow fan-shaped structure. After fitting together, a sealed space is formed. The system clamps and secures the fecal sample. This sealed design ensures the sample remains stable during transfer to the sampling bottle 1, effectively preventing spillage due to hand shake. After inserting the sampling component 8, which clamps the sample, into the sampling bottle 1, the threaded column 9 is rotated in the opposite direction, causing the auxiliary component 10 and the sampling component 8 to move downwards as a whole. At this point, the force exerted by the internal column 4 on the connecting rod 801 disappears. Under the elastic reset action of the connecting spring 1004 in the auxiliary component 10, the connecting rod 801 moves outwards, thereby causing the four sets of sampling plates 802 and end plates 803 to move away from each other. The fecal sample clamped inside falls into the sampling bottle 1. During sample release, the sampling plates 802 and end plates 803... The slow movement of the sample ensures stable contact between the sample and the buffer or treatment solution inside the bottle. At the same time, the sampling component 8 rotates in the buffer solution with the rotation of the threaded column 9, which further promotes the thorough mixing of the sample and the treatment solution, forming a uniform fecal treatment solution and improving the accuracy of subsequent tests. After the sample is mixed, the rubber cap 3 on the top of the sealing bottle cap 2 is removed. At this time, the end of the pipette 5 is no longer blocked by the plug column 7. The sampling bottle body 1 is made of rubber. The user holds the sampling bottle body 1 and tilts it at a certain angle. Using the suction function of the pipette 5, the user accurately draws out the mixed fecal treatment solution inside the bottle. Then, the treatment solution is slowly dripped into the corresponding reagent plate detection well, completing the sample preparation work before the test. The routine reagent plate test operation can then be carried out.

9. The sampling bottle for fecal sampling according to claim 8, wherein The operation method is as follows: In the initial state, the sampling bottle (1) and the sealing cap (2) are tightly connected by threads to ensure overall sealing. The cap (3) is snapped onto the top outer surface of the sealing cap (2). The plug (7) inside is located at the top of the pipette (5). The pipette (5) is sealed by the plug (7) to further ensure the sealing of the sampling bottle (1) and prevent leakage of the internal buffer solution or treatment solution. At this time, the four sampling plates (802) and the end plates (803) of the sampling assembly (8) are far apart from each other, which facilitates subsequent sampling operations. The user can use the striped columns (11) distributed in a ring on the outer surface of the sealing cap (2) (the striped columns and the sealing cap are integrated into a structure) to provide sufficient frictional resistance. Turn the bottle cap (2) to separate it from the threads of the sampling bottle body (1). Then, align the sampling plate (802) and end plate (803) at the end of the connecting rod (801) in the sampling assembly (8) with the target fecal area to complete the sampling positioning. The user rotates the threaded column (9) inside the built-in column (4). The threaded column (9) drives the auxiliary assembly (10) and the sampling assembly (8) connected to it to move upward as a whole. During this process, the built-in column (4) applies a force to the connecting rod (801) of the sampling assembly (8) from the outside. The connecting rod (801) deflects with the help of the rotational cooperation between the connecting plate (1002) and the connecting shaft (1003) in the auxiliary assembly (10), so that the four sets of sampling plates (802) and end plates (803) come closer to each other and fit tightly together. The sampling plate and end plate are integrated into a hollow fan-shaped structure. After fitting together, they form a sealed space to clamp and fix the fecal sample. This sealed design ensures that the sample remains stable during the transfer to the sampling bottle (1) and effectively prevents the sample from spilling due to unstable hand-holding. After inserting the sampling component (8) with the sample clamped into the sampling bottle (1), the threaded column (9) is rotated in the opposite direction, which drives the auxiliary component (10) and the sampling component (8) to move down as a whole. At this time, the force of the built-in column (4) on the connecting rod (801) disappears. The connecting rod (801) moves outward under the elastic reset action of the connecting spring (1004) in the auxiliary component (10), which in turn drives the four sets of sampling plates (802) and end plates (803) to move together. As the sample moves away, the fecal sample held inside falls into the sampling bottle (1). During the sample release process, the slow movement of the sampling plate (802) and end plate (803) ensures that the sample is in stable contact with the buffer solution or treatment solution inside the bottle. At the same time, the sampling component (8) rotates in the buffer solution with the rotation of the threaded column (9), which can further promote the thorough mixing of the sample and the treatment solution, forming a uniform fecal treatment solution and improving the accuracy of subsequent detection. After the sample is mixed, the cap (3) on the top of the sealed bottle cap (2) is removed. At this time, the end of the pipette (5) is no longer blocked by the plug (7). The sampling bottle (1) is made of rubber. The user holds the sampling bottle (1) and tilts it at a certain angle. Using the suction function of the pipette (5), the user can accurately extract the mixed fecal treatment solution inside the bottle.Subsequently, the processing liquid is slowly added into the corresponding reagent plate detection hole to complete the sample preparation before detection, and subsequent conventional reagent plate detection operation can be carried out.
