Description

Technical Field

[0001] This utility model relates to the field of fecal sampling technology, specifically to a fecal sampler. Background Technology

[0002] Stool examination is a routine clinical test that plays an important role in the diagnosis and treatment of clinical diseases. This examination provides a relatively direct view of some pathological phenomena in the gastrointestinal tract and indirectly assesses the functional status of the digestive tract, pancreas, liver, and gallbladder.

[0003] Current technology typically uses a threaded connection between the cap and the body of a fecal sampler. This connection requires a significant number of rotations to complete the sampling process, causing inconvenience for the user. Especially during actual operation, the increased number of rotations can lead to greater operational complexity, particularly when dealing with a large number of samples or in urgent and inconvenient situations, making ease of operation and efficiency paramount. Utility Model Content

[0004] This application provides a fecal sampler to at least solve the above-mentioned technical problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fecal sampler, comprising a container filled with a buffer solution; a cap connected to the container; a sampling rod connected to the cap, wherein the container has an open end for inserting the sampling rod; and a connecting part, wherein the cap is connected to the container via the connecting part.

[0006] The connecting part includes a guide surface disposed on the peripheral side of the container and facing the opening end. The guide surface is divided into a proximal end and a distal end along the axial direction of the container. The proximal end is closer to the opening end than the distal end. A protruding ring is disposed on the peripheral side of the container and on the side of the guide surface away from the opening end. A guide rib is disposed on the inner wall of the bottle cap. A buckle rib is disposed on the inner wall of the bottle cap. When the guide rib slides along the guide surface from the proximal end to the distal end, the bottle cap is connected to the container and the buckle rib is fastened to the protruding ring. When the guide rib slides along the guide surface from the distal end to the proximal end, the bottle cap is detached from the container and the buckle rib is separated from the protruding ring.

[0007] Furthermore, a guide groove is provided on the peripheral side of the container, and a guide surface is formed on the inner wall of the guide groove.

[0008] Furthermore, there are two guide surfaces, which are two inner wall surfaces of the guide groove arranged opposite each other, and the two guide surfaces share a common distal end.

[0009] Furthermore, there are at least two guide grooves, and adjacent guide surfaces of adjacent guide grooves share a proximal end.

[0010] Furthermore, the container is provided with a dropper at the end away from the cap, and the dropper is provided with a dripping hole that communicates with the inside of the container. A filter element is provided inside the dripping hole to filter particles in the liquid in the container.

[0011] Furthermore, the container portion is made of a soft material.

[0012] Furthermore, the end of the dropper furthest from the bottle cap is provided with a cap, and an inner plug is provided inside the cap. When the cap is closed on the dropper, the inner plug is located inside the drip hole.

[0013] Furthermore, the bottle cap includes a cap body, and a handle is provided on the side of the cap body away from the container, the handle being flat.

[0014] Furthermore, the outer side of the handle is provided with anti-slip teeth, and the connection between the handle and the cover is provided with a transition slope.

[0015] Furthermore, a toothed sampling head is provided on the side of the sampling rod away from the bottle cap.

[0016] Compared with existing technologies, the advantages of this invention are as follows: When it is necessary to fully mix the sample on the sampling stick with the buffer solution in the container, first insert the sampling stick into the container from the open end. The cap moves towards the open end along with it. The guide rib on the cap slides from the proximal end to the distal end along the guide surface on the container. At the same time, the buckle on the cap gradually engages with the convex ring on the circumference of the container. Through this process, the cap is smoothly installed on the container and a seal is achieved. Conversely, when the cap needs to be removed from the container, rotate the cap so that it rotates relative to the container. The guide rib on the cap slides from the distal end back to the proximal end along the guide surface, the buckle separates from the convex ring, and the cap can be easily removed, thus opening the cap. The entire process, through the unique connection design between the cap and the container, ensures that the installation and removal of the cap are simple and reliable.

[0027] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Please see Figure 1 and Figure 2 This embodiment provides a fecal sampler, including a container 1 containing a buffer solution. An open end 11 is provided at one end of the container 1, and a cap 2 is provided at the open end 11 to seal it. A sampling rod 3 is fixedly mounted on the cap 2, and a toothed sampling head 31 is provided on the side of the sampling rod 3 away from the cap 2. The toothed sampling head 31 collects the sample. The number and size of the teeth in the toothed sampling head 31 can be selected according to the sampling volume.

[0029] Please see Figure 2 and Figure 3 When the bottle cap 2 closes the opening end 11, the sampling rod 3 extends into the container 1 through the opening end 11. The sample collected by the sampling rod 3 is mixed with the buffer solution in the container 1 to complete the mixing.

[0030] The inner wall of container 1 is provided with sealing ribs 8. After the sampling rod 3 is inserted into container 1, the sealing ribs 8 are located around the sampling rod 3. The sealing effect of container 1 is achieved by the cooperation of the sealing ribs 8 and the sampling rod 3, reducing the leakage of liquid from the opening end 11.

[0031] In existing technologies, the bottle cap 2 and container 1 are typically connected by a threaded connection. This connection method requires a relatively large number of rotations to complete the sampling operation, which is inconvenient for the user. Especially when there are many samples or when processing is urgent and inconvenient, the ease and efficiency of operation become particularly important.

[0032] Please see Figure 4 and Figure 5 To address the aforementioned technical issues, a connecting portion 4 is provided between the bottle cap 2 and the container 1. The connecting portion 4 includes a guide surface 41 disposed on the peripheral side of the container 1 and facing the opening end 11. The guide surface 41 is divided into a proximal end 411 and a distal end 412 along the axial direction of the container 1. The proximal end 411 is closer to the opening end 11 than the distal end 412. A protruding ring 42 is provided on the peripheral side of the container 1 on the side of the guide surface 41 away from the opening end 11. A guide rib 43 and a retaining rib 44 are provided on the inner wall of the bottle cap 2. When the guide rib 43 slides along the guide surface 41 from the proximal end 411 to the distal end 412, the bottle cap 2 is connected to the container 1, and the retaining rib 44 is fastened to the protruding ring 42. When the guide rib 43 slides along the guide surface 41 from the distal end 412 to the proximal end 411, the bottle cap 2 is detached from the container 1, and the retaining rib 44 is separated from the protruding ring 42.

[0033] When it is necessary to fully mix the sample on the sampling stick 3 with the buffer solution in the container 1, first insert the sampling stick 3 into the container 1 from the open end 11. The cap 2 moves towards the open end 11 along with it. The guide rib 43 on the cap 2 will slide from the proximal end 411 to the distal end 412 along the guide surface 41 on the container 1. At the same time, the buckle rib 44 of the cap 2 gradually engages with the convex ring 42 on the circumference of the container 1. Through this process, the cap 2 is successfully installed on the container 1 and sealed. Conversely, when the cap 2 needs to be removed from the container 1, rotate the cap 2 so that the cap 2 rotates relative to the container 1. The guide rib 43 on the cap 2 will slide from the distal end 412 back to the proximal end 411 along the guide surface 41. The buckle rib 44 separates from the convex ring 42, and the cap 2 can be easily removed to open the container. The entire process, through the unique design of the connection part 4 between the cap 2 and the container 1, ensures that the installation and removal of the cap 2 is simple and reliable.

[0034] The guide surface 41 is specifically formed by the inner wall of the guide groove 45 opened on the side of the container 1, such as... Figure 5 As shown, there are two guide surfaces 41, which are two inner walls of the guide groove 45 that are arranged opposite to each other. The two guide surfaces 41 share a common distal end 412.

[0035] When the bottle cap 2 closes the opening end 11, the guide rib 43 moves along the inner wall of the guide groove 45 from the edge of the guide groove 45 to the bottom of the guide groove 45, that is, from the near end 411 of the guide surface 41 to the far end 412 of the guide surface 41. The guide rib 43 is guided by the inner wall of the guide groove 45 to move along a preset path. The specific operation process is as follows: when the bottle cap 2 closes the opening end 11, the guide rib 43 on the bottle cap 2 is inserted into the guide groove 45 until it contacts the inner wall of the guide groove 45. Under the guidance of the inner wall of the guide groove 45, that is, under the guidance of the guide surface 41, the guide rib 43 moves in a straight line or curve along the path of the guide groove 45 until it reaches the common far end 412 of the guide groove 45, so as to achieve precise guidance or limiting. At this time, the buckle rib 44 of the bottle cap 2 is fastened to the convex ring 42 on the side of the container 1.

[0036] This connection method introduces a non-directional unscrewing method. Whether twisting clockwise to the right or counterclockwise to the left, the cap 2 can be easily unscrewed, greatly simplifying the operation process and enabling any user to quickly and easily complete the sampling operation, thus improving the ease of operation and safety.

[0037] Please see Figure 5 In order to facilitate the sealing of the bottle cap 2 at any angle and guide the sliding of the guide rib 43, there are at least two guide grooves 45, and the adjacent guide surfaces 41 of adjacent guide grooves 45 share a proximal end 411. That is, the guide grooves 45 opened on the side of the container 1 will form a circle around the opening end 11, and adjacent guide grooves 45 are in contact.

[0038] After the collected feces are mixed with the buffer solution, the mixture is usually dripped directly onto the detection plate through the dripping hole 51 inside the dripper 5 located at the bottom of the container 1 for detection. However, since feces contain a large number of solid particles, these particles can easily pass through the dripper 5, ultimately affecting the accuracy of the test results and causing some components to be undetectable.

[0039] Please see Figure 2 and Figure 3 To address the aforementioned technical issues, a dropper 5 is provided at the end of container 1 furthest from the cap 2. The dropper 5 has a dripping hole 51 connected to the interior of container 1. A filter element 6 is installed inside the dripping hole 51 to filter particles from the liquid in container 1. The filter element 6 is typically made of a porous material, allowing larger particles to pass through and be intercepted, thus reducing the impact on the test results.

[0040] To facilitate faster flow of the mixture in container 1 from dripper 5, part of container 1 is made of soft material. By manually squeezing the soft material part of container 1, the internal volume of container 1 is deformed, thereby increasing the internal pressure of container 1 and accelerating the flow of the mixture from dripper 5.

[0041] Please see Figure 2 and Figure 6 The dropper 5 has a cap 7 at the end furthest from the bottle cap 2. An inner plug 71 is located inside the cap 7. When the cap 7 closes the dropper 5, the inner plug 71 partially resides within the droplet orifice 51. The cap 7 can be threaded onto the container 1 to engage with the dropper 5. When the sample on the sampling rod 3 mixes with the buffer solution in the container 1, the cap 7 closes onto the dropper 5, and the inner plug 71 blocks the droplet orifice 51, preventing liquid from flowing out of the container 1.

[0042] Please see Figure 2 and Figure 4 The bottle cap 2 includes a cap body 21. A handle 22 is provided on the side of the cap body 21 away from the container 1. The connection between the handle 22 and the cap body 21 forms a baffle that is away from the container 1.

[0043] When the bottle cap 2 is screwed relative to the container 1, it is usually quite smooth, which can easily cause the user to slip during operation. To address this technical problem, the bottle cap 2 has been designed in a specific way. The bottle cap 2 includes a cap body 21, which is cylindrical. A handle 22 is provided on the side of the cap body 21 away from the container 1. The handle 22 is flat. The flat handle 22 facilitates hand rotation, better generates torque force, and reduces slippage.

[0044] Furthermore, the outer side of the handle 22 is provided with anti-slip teeth 23, and a transition slope 24 is provided at the connection between the handle 22 and the cover 21. The anti-slip teeth 23 increase the friction and further reduce slippage.

[0045] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this application can be achieved, and this is not limited herein.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0047] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
