Description

Technical Field

[0001] This invention belongs to the field of medical supplies, and particularly relates to an integrated sampling bottle and sampling device. Background Technology

[0002] Currently, our company's marketed fecal sampling bottles use a split-type threaded connection structure, comprising multiple independent parts such as the bottle body, cap, sealing ring, and stirring spoon. This assembly process is cumbersome, resulting in low production efficiency. Furthermore, patients are prone to accidentally unscrewing the threaded connection, affecting the sampling seal. In addition, traditional sampling bottles have limited functionality and lack an effective area for worm egg accumulation. The simple structure of the stirring spoon makes it prone to liquid "encapsulation" during stirring, leading to uneven mixing and sample adhesion to the spoon surface, thus affecting testing accuracy.

[0003] Based on the above problems, the sampling bottles in the existing technology have the following drawbacks: 1. The number of parts is large, the assembly process is complex, and the production efficiency is low; 2. Threaded connections are prone to user misoperation, which can damage the seal. 3. There is no dedicated structure for collecting insect eggs, which is not conducive to subsequent microscopic detection; 4. The stirring spoon has low stirring efficiency, which can easily lead to uneven stirring and sample residue.

[0004] Therefore, there is an urgent need to design a sampling bottle to solve the problems mentioned above. Summary of the Invention

[0005] To address the technical problems mentioned in the background art, such as numerous parts, easy misoperation, limited functionality, poor stirring effect, uneven force on one side of the locking mechanism leading to twisting and deformation, and limited tensile strength, an integrated sampling bottle and sampling device are provided.

[0006] To achieve the above objectives, the specific technical solution of the integrated sampling bottle and sampling device of the present invention is as follows: An integrated sampling bottle for stirring and enriching parasite eggs in feces, comprising: The bottle body has a sloping bottom, with the downward slope of the sloping surface designed as an accumulation zone for insect eggs. A stirring assembly is detachably connected to the bottle body and can extend into the interior of the bottle body. The stirring assembly includes a serrated portion to fully stir the medium inside the bottle body. The filter assembly is inserted into the bottle body and separates the stirring assembly and the enrichment zone. The filter assembly is used to filter the medium after the stirring assembly stirs it, and guide the filtered medium through the inclined plane to the enrichment zone.

[0007] Furthermore, the bottle body includes a bottle body and a bottle cap that is rotatably mounted on the bottle body. The bottle cap is detachably connected to the stirring assembly, and the bottom of the bottle body is provided with a slope.

[0008] Furthermore, the bottle body also includes a connecting sleeve, through which the stirring assembly is detachably connected to the bottle cap.

[0009] Furthermore, the bottle body also includes a screw cap, which is rotatably mounted on the bottle cap for opening or closing the opening on the bottle cap.

[0010] Furthermore, the integrated sampling bottle also includes a first locking block and a first locking slot that can be interlocked with each other, and a second locking block and a second locking slot that can be interlocked with each other; One of the first card block and the first card slot is disposed in the stirring assembly, and the other is disposed in the connecting sleeve; One of the second card block and the second card slot is located on the bottle cap, and the other is located on the connecting sleeve.

[0011] Furthermore, the bottle cap is provided with a fixing cavity, the top of the fixing cavity is lower than the top of the bottle cap, so that a fixing step is formed between the top of the bottle cap and the fixing cavity, and the bottom of the fixing cavity is lower than the bottom of the bottle cap, and the filter assembly is snapped onto the fixing step.

[0012] Furthermore, the stirring assembly includes: The snap-fit ​​part is used for detachable connection with the bottle body; The stirring rod is connected to the snap-fit ​​part and can extend into the bottle body. The serrated part is set on the stirring rod and rotates together with the stirring rod. There are multiple serrated parts, which are evenly distributed along the center circumference of the stirring rod.

[0013] Furthermore, the stirring assembly also includes a stirring spoon, which is located at the end of the stirring rod away from the locking part.

[0014] Furthermore, the top of the snap-fit ​​part is provided with a rotating groove, which is in the shape of a straight line, a cross, or a plum blossom.

[0015] A sampling device comprising several integrated sampling bottles.

[0016] The integrated sampling bottle of this invention has the following advantages: By setting an inclined slope at the bottom of the bottle and forming an "egg enrichment zone" at its lowest point, the high-density eggs naturally settle and concentrate in this area using gravity, significantly improving the sampling accuracy and efficiency during subsequent microscopic detection. The serrated design on the stirring assembly effectively breaks up clumps in the fecal sample, avoiding the "liquid encapsulation" phenomenon (i.e., the outer layer of liquid encapsulates the inner layer of unmixed sample) caused by traditional smooth stirring spoons, ensuring that the sample is fully homogenized and reducing residues and detection errors. The filtration assembly separates the stirring zone from the enrichment zone. After stirring, the liquid can be poured or guided through the filter screen to achieve preliminary solid-liquid separation, allowing only fine particles (including eggs) to enter the enrichment zone and preventing large impurities from interfering with the detection results. Integrating stirring, filtration, and enrichment functions into a single container, users can complete the entire pretreatment process without transferring samples, reducing the risk of cross-contamination and improving ease of use.

[0017] The sampling device of this invention has the following advantages: The device comprises multiple integrated sampling bottles, allowing for multiple samplings of the same patient (e.g., three tests every three days) or group screening of multiple individuals, thus improving the efficiency of epidemiological investigations. All sampling bottles adopt the same structural design, and the matching reagents, operating procedures, and testing methods can be standardized, facilitating the establishment of standardized fecal examination procedures in medical institutions. Multiple sampling bottles can be arranged into a box-like device (e.g., a 96-well plate design), facilitating storage, transportation, and instrumentation, and ensuring compatibility with existing laboratory automation platforms. Medical personnel can receive the complete sampling device at once, along with instructions and numbered labels, helping patients complete sampling on time and in sequence, reducing omissions or confusion. In scenarios requiring high-throughput sample collection, such as parasite screening and early colorectal cancer screening, this device can significantly improve organizational efficiency and data quality.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0024] The following is a reference to the appendix. Figure 1 To be continued Figure 4 This invention describes an integrated sampling bottle and sampling device.

[0025] This embodiment provides an integrated sampling bottle for stirring and enriching parasite eggs in feces, such as... Figure 1 and Figure 2 As shown, the integrated sampling bottle includes a bottle body 1, a stirring assembly 2, and a filtering assembly 3. The bottom of the bottle body 1 is provided with a slope 111, and the downward slope direction of the slope 111 is set as the enrichment zone 112 for insect eggs. The stirring assembly 2 is detachably connected to the bottle body 1 and can extend into the interior of the bottle body 1. The stirring assembly 2 includes a serrated part 21 to fully stir the medium inside the bottle body 1. The filtering assembly 3 is inserted into the bottle body 1 and separates the stirring assembly 2 from the enrichment zone 112. The filtering assembly 3 is used to filter the medium after the stirring assembly 2 stirs it and guide the filtered medium through the slope 111 to the enrichment zone 112.

[0026] Understandably, by setting an inclined slope 111 at the bottom of the bottle 1 and forming an "egg enrichment zone 112" at its lowest point, the high-density eggs naturally settle and concentrate in this area using gravity, significantly improving the sampling accuracy and efficiency during subsequent microscopic detection. The serrated part 21 on the stirring assembly 2 effectively breaks up clumps in the fecal sample, avoiding the "liquid encapsulation" phenomenon (i.e., the outer layer of liquid encapsulates the inner layer of unmixed sample) caused by the traditional smooth stirring spoon 24, ensuring that the sample is fully homogenized and reducing residues and detection errors. The filtration assembly 3 separates the stirring zone from the enrichment zone 112. After stirring, the liquid can be poured or guided through the filter screen to achieve preliminary solid-liquid separation, allowing only fine particles (including eggs) to enter the enrichment zone 112, preventing large impurities from interfering with the detection results. Integrating the three major functions of stirring, filtering, and enrichment into a single container, users can complete the entire pretreatment process without transferring samples, reducing the risk of cross-contamination and improving ease of use.

[0027] Furthermore, such as Figure 3 As shown, the bottle body 1 includes a bottle body 11 and a bottle cap 12 rotatably disposed on the bottle body 11. The bottle cap 12 is detachably connected to the stirring assembly 2. The bottom of the bottle body 11 is provided with a slope 111.

[0028] Understandably, the bottle cap 12 connects to the bottle body 11 via a rotating mechanism, which makes it easier to identify the open / closed state compared to traditional threaded structures, preventing accidental tightening by patients and thus ensuring a seal. Simultaneously, the rotating structure distributes force evenly, resulting in more consistent compression of the sealing ring and more stable sealing performance. The stirring component 2 is detachably connected via the bottle cap 12, allowing users to directly remove the stirring rod 23 after opening the cap 12 for stirring. Afterward, it can be re-secured, making the operation intuitive, time-saving, and labor-saving. The stirring component 2 is housed within the bottle cap 12, forming an integrated "cap as tool" design, preventing parts loss and making it particularly suitable for home scavenging scenarios, thus enhancing the user experience.

[0029] Furthermore, such as Figure 1 and Figure 2As shown, the bottle body 1 also includes a connecting sleeve 13, and the stirring assembly 2 is detachably connected to the bottle cap 12 through the connecting sleeve 13.

[0030] Understandably, the introduction of the connecting sleeve 13 as an intermediate transition component makes the connection between the stirring assembly 2 and the bottle cap 12 more secure, avoiding wear or loosening of the interface due to frequent insertion and removal, and extending the product's service life. The connecting sleeve 13 can be pre-assembled onto the bottle cap 12 or the stirring assembly 2, enabling step-by-step assembly, reducing the difficulty of overall machine assembly, improving production line efficiency, and making it suitable for large-scale manufacturing. The connecting sleeve 13 provides guidance and limiting functions, making the insertion of the stirring assembly 2 smoother and more precise, reducing misalignment or jamming, and improving operational comfort.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, the bottle body 1 also includes a screw cap 14, which is rotatably mounted on the bottle cap 12 and is used to open or close the opening on the bottle cap 12.

[0032] Understandably, adding an independent screw cap 14 to the bottle cap 12 creates a double-layer sealing structure of "outer screw cap 14 + inner bottle cap 12," effectively preventing accidental opening during transportation. This is particularly suitable for high-safety scenarios such as the transport of biological samples. The screw cap 14 requires active rotation to open, unlike simple press or push-pull mechanisms, significantly reducing the possibility of accidental opening or leakage due to children squeezing it, meeting medical product safety standards. The screw cap 14 is typically equipped with arrow markings or color indicators, allowing users to clearly determine whether it has been properly closed, avoiding sample contamination or invalidation due to negligence.

[0033] Furthermore, such as Figure 4 As shown, the integrated sampling bottle also includes a first locking block 41 and a first locking slot 42 that can be interlocked with each other, and a second locking block 43 and a second locking slot 44 that can be interlocked with each other; one of the first locking block 41 and the first locking slot 42 is disposed on the stirring assembly 2, and the other is disposed on the connecting sleeve 13; one of the second locking block 43 and the second locking slot 44 is disposed on the bottle cap 12, and the other is disposed on the connecting sleeve 13.

[0034] Understandably, the dual-clamping structure (first and second clamping blocks 43 / slots) constitutes an asymmetrical fitting mechanism, ensuring that the mixing component 2 can only be installed in one correct orientation, avoiding mixing failure or equipment damage due to reverse installation. Multi-point clamping is more resistant to external impacts and vibrations than single-point connections, maintaining the component's stability and preventing it from falling off during transportation or violent shaking. The clamping structure requires no screws or adhesives, achieving "plug and play," which is convenient for users and facilitates rapid factory assembly and subsequent recycling. All components are tightly joined by precision snap-fits, resulting in a smooth and seamless appearance, enhancing the product's quality and professional image.

[0035] Furthermore, a fixing cavity is provided inside the bottle body 11, the top of the fixing cavity is lower than the top of the bottle body 11, so that a fixing step is formed between the top of the bottle body 11 and the fixing cavity, and the bottom of the fixing cavity is lower than the bottom of the bottle cap, and the filter assembly 3 is snapped onto the fixing step.

[0036] Understandably, the fixed step structure formed by the fixed cavity and the bottle body 11 can support the fixed protrusion of the filter assembly 3 during installation, achieving axial limitation, preventing the filter assembly 3 from being over-inserted or loosened, and ensuring that the depths of both are consistent. The outer wall of the fixed cavity fits tightly with the inner wall of the connecting hole, playing a guiding and sealing auxiliary role, reducing shaking gaps, and improving the sealing and stability of the overall structure. The fixed step evenly transfers the load to the bottle body 11, avoiding breakage or deformation of the connection parts due to excessive local stress, which is especially suitable for mass-produced injection molded parts made of plastic. The height difference of the fixed step can be used as a visual or mechanical sensing reference, making it easier for automated production lines to determine whether the components are fully assembled.

[0037] Furthermore, such as Figure 2 As shown, the stirring assembly 2 includes a snap-fit ​​part 22 and a stirring rod 23. The snap-fit ​​part 22 is used for detachable connection with the bottle body 1. The stirring rod 23 is connected to the snap-fit ​​part 22 and can extend into the bottle body 1. A serrated part 21 is provided on the stirring rod 23 and rotates together with the stirring rod 23. There are multiple serrated parts 21, which are evenly distributed along the center circumference of the stirring rod 23.

[0038] Understandably, the multiple serrated sections 21 are evenly distributed circumferentially, generating omnidirectional shearing disturbance when the stirring rod 23 rotates, breaking down the surface tension and adhesion of fecal clumps, achieving rapid and thorough homogenization. The evenly distributed serrated structure, combined with the rotational motion, can cover a larger stirring range, especially suitable for conical or curved-bottom bottles 11, effectively eliminating mixing blind spots at the bottom or edges. The snap-fit ​​section 22 is designed for detachable connection, combining the aforementioned snap-fit ​​blocks / slots and fixing steps to achieve a multi-confirmation mechanism of "listening to the sound, checking the wires, and feeling the surface," ensuring reliable installation every time. The stirring rod 23 and the snap-fit ​​section 22 are designed separately, allowing for individual replacement if one part is damaged, reducing maintenance costs; it can also be used to adapt to samples of different sizes.

[0039] Furthermore, such as Figure 2 As shown, the stirring assembly 2 also includes a stirring spoon 24, which is disposed at the end of the stirring rod 23 away from the locking part 22.

[0040] Understandably, the stirring spoon 24, located at the bottom, moves closely to the bottle wall during stirring, effectively scraping away fecal samples adhering to the bottle wall, preventing loss due to residue buildup, and improving sample utilization. Users can directly scoop an appropriate amount of sample from the excrement into the bottle using the stirring spoon 24, achieving "one device for multiple uses" without the need for an additional sampling spoon, simplifying packaging and usage. At the end of stirring, the spoon-shaped structure agitates the bottom sediment, resuspending it in the solution, further improving the egg release rate and detection sensitivity. The spoon-shaped structure offers a comfortable grip, suitable for various users (such as the elderly or those with hand disabilities), enhancing the product's versatility.

[0041] Furthermore, the top of the snap-fit ​​part 22 is provided with a rotating groove 221, which is in the shape of a straight line, a cross, or a plum blossom.

[0042] This embodiment also provides a sampling device comprising several integrated sampling bottles. This sampling device includes multiple integrated sampling bottles, which can be used for multiple samplings of the same patient (e.g., three tests every three days) or for group screening of multiple patients, improving the efficiency of epidemiological investigations. All sampling bottles adopt the same structural design, and the matching reagents, operating procedures, and testing methods can be uniformly formulated, which is conducive to establishing standardized fecal examination operation procedures in medical institutions. Multiple sampling bottles can be arranged into a box-like device (e.g., a 96-well plate design), facilitating storage, transportation, and machine testing, and is compatible with existing laboratory automation platforms. Medical personnel can receive the entire sampling device at once, along with instructions for use and numbered labels, to help patients complete sampling on time and in sequence, reducing omissions or confusion. In scenarios requiring high-throughput sample collection, such as parasite screening and early colorectal cancer screening, this device can significantly improve organizational efficiency and data quality.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
