The drawings are schematic or conceptual drawings, and the relationship between the thickness and width of each part, as well as the proportional relationship between each part, etc., is not exactly the same as the actual value.
[0048] Figures 1 to 3 The structure of the excrement sampling and detecting device of one embodiment of the present application is shown, which includes a container body 100, a sampling assembly 200 and a limiting assembly 300.
[0049] As shown in Figure 4 and Figure 5 , the container body 100 includes a first tube 110 and a second tube 120, the first tube 110 and the second tube 120 are arranged side by side, and both are connected at the bottom of the container body 100.
[0050] The first tube body 110 has an open end and is connected with the second tube body 120 at the other end. The first tube body 110 is provided with a rotating assembly 130, which has a cylindrical structure and can rotate in the first tube body 110. The rotating assembly 130 is perpendicular to the length direction of the first tube body 110. The rotating assembly 130 includes a hollow channel 131. The rotating assembly 130 defines a first state and a second state according to its rotating position. When the rotating assembly 130 is in the first state, the first tube body 110 is divided into a first tube body upper part 111 and a first tube body lower part 112, i.e. the first tube body 110 is isolated into two parts by the rotating assembly 130, and the first tube body upper part 111 and the first tube body lower part 112 are not connected. When the rotating assembly 130 is in the second state, the hollow channel 131 is positioned to connect the first tube body upper part 111 and the first tube body lower part 112. Figure 2 and Figure 4 When the rotating assembly 130 is in the second state, the hollow channel 131 is positioned to connect the first tube body upper part 111 and the first tube body lower part 112. Figure 3 A filtrate assembly (not shown in the figure) is arranged in the hollow channel 131. The filtrate assembly is a filter core suitable for filtering liquid. The filter core is fixed in the hollow channel 131 and has a contour that is adapted to the hollow channel 131. Preferably, the hollow channel 131 and the filter core have a cylindrical structure.
[0051] The second tube body 120 has a closed end and is connected with the first tube body 110 at the other end. The second tube body 120 is provided with a mounting groove 121, and a test strip 400 is arranged in the mounting groove 121, with one end close to or contacting the bottom of the container body 100. The test strip 400 is used for fecal sampling detection, such as colloidal gold immunochromatography.
[0052] As shown in Figure 6 and Figure 7 The sampling assembly 200 includes a cap 210 and a sampling rod 220. The sampling rod 220 is connected to the cap 210 and can be extended into the first tube body 110. The cap 210 can seal the opening of the first tube body 110 and can continue to move a predetermined distance towards the first tube body 110.
[0053] The cap 210 is provided with a sealing assembly 211, which can be made of materials such as rubber and silicone that have a certain elasticity. The side contour of the sealing assembly 211 is adapted to the inner surface of the first tube body 110, so as to be suitable for sealing the opening of the first tube body 110. During the process of the cap 210 sealing the opening of the first tube body 110 and continuing to move towards the first tube body 110, the sealing assembly 211 is deepened into the first tube body 110 and always seals one end of the first tube body 110.
[0054] The inside of the first tube body 110 has a variable diameter tube section 113, which has a relatively larger diameter near the opening of the first tube body 110. The end surface of the sealing assembly 211 is adapted to the inner surface of the variable diameter tube section 113, so that when the inner surface of the variable diameter tube section 113 contacts the end surface of the sealing assembly 211 during the insertion of the sealing assembly 211 into the first tube body 110, the limit position of the movement of the cap 210 towards the first tube body 110 is defined.
[0055] The sampling rod 220 has an overall elongated cylindrical structure, and a thread 221 is provided at one end of the sampling rod 220 to facilitate the collection of a fecal sample. The length of the sampling rod 220 is such that it does not touch the rotating assembly 130 inside the first tube body 110 when the cap 210 moves to the limit position towards the first tube body 110.
[0056] The limiting assembly 300 cooperates with the sampling assembly 200, and specifically, the limiting assembly 300 is detachably connected to the cap 210. The limiting assembly 300 includes a protruding portion 310, and the cap 210 is provided with a slot 212 adapted to the insertion of the protruding portion 310, so that by inserting the protruding portion 310 into the slot 212, the limiting assembly 300 is connected to the cap 210. When the cap 210 closes the opening of the first tube body 110 and further moves towards the first tube body 110, the distance that it can move is limited by the limiting assembly 300 connected thereto, i.e., when the limiting assembly 300 abuts against the container body 100, the cap 210 cannot continue to move towards the first tube body 110, so that the limit position of the movement of the cap 210 towards the first tube body 110 is defined by the limiting assembly 300.
[0057] The rotating assembly 130 has an overall cylindrical structure, and a protruding positioning ring 132 is provided at a position near each end thereof, and a positioning groove 114 adapted to the positioning ring 132 is provided on the side wall of the first tube body 110, so that the installation position of the rotating assembly 130 is defined by the cooperation of the two. The positioning ring 132 can be a flexible ring, such as an O-ring made of silicone or rubber, which is fixed on the cylindrical structure of the rotating assembly 130, or the rotating assembly 130 as a whole is made of silicone or rubber, which has a certain elasticity. In this way, the assembly of the rotating assembly 130 and the first tube body 110 is facilitated, so that the positioning ring 132 can be embedded into the positioning groove 114 on the side wall of the first tube body 110 by external force, and the sealing property of the assembly of the rotating assembly 130 and the first tube body 110 is also considered.
[0058] For the rotation of the rotating assembly 130 relative to the first pipe body 110, the rotation should be arranged to require the help of a certain external force, rather than being able to easily rotate, by adjusting the size of the rotating assembly 130 or the positioning ring 132 positioned thereon, the external force required to drive the rotating assembly 130 is easily defined. The rotation of the rotating assembly 130 is to adjust its state, i.e. the first state and the second state in the above, in order to facilitate the rotation of the rotating assembly 130, a groove 133 is arranged on the end face of the first pipe body 110 exposed to the rotating assembly 130, the groove 133 is matched with the protruding portion 310 of the limiting assembly 300, so that the protruding portion 310 can be embedded in the groove 133, by driving the limiting assembly 300 to drive the rotating assembly 130 to rotate, and finally adjust the rotating assembly 130 to the required state.
[0059] A slope structure 140 is arranged at the bottom of the container body 100, i.e. the position where the first pipe body 110 and the second pipe body 120 are communicated, the slope height of the slope structure 140 gradually decreases from the first pipe body 110 to the second pipe body 120, thereby facilitating the liquid flowing out of the first pipe body 110 to converge into the second pipe body 120.
[0060] The excrement sampling and detecting device of the utility model is used, and its structure is as shown in Figure 2 The cap 210 of the sampling assembly 200 is closed to the opening of the first pipe body 110, the limiting assembly 300 abuts against the container body 100, so that the cap 210 cannot be further moved to the direction of the first pipe body 110. At the same time, the rotating assembly 130 is arranged in the first state, i.e. the rotating assembly 130 isolates the first pipe body upper portion 111 and the first pipe body lower portion 112, specifically, the axial direction of the hollow passage 131 of the rotating assembly 130 is perpendicular to the extension direction of the first pipe body 110. The sample diluent is arranged in the first pipe body upper portion 111 and is used for diluting the excrement sample for detection.
[0061] The use method of the excrement sampling and detecting device of the utility model is as follows:
[0062] 1. The sampling assembly 200 is pulled out from the container body 100, at this time the limiting assembly 300 is still in the connected state with the sampling assembly 200.
[0063] 2. The sampling rod 220 of the sampling assembly 200 is inserted into 5 different positions of the solid excrement for sampling in sequence, and is inserted to the upper portion of the thread 221 of the sampling rod 220 each time.
[0064] 3. The sampling assembly 200 is restored to the connected position of the container body 100.
[0065] 4, shake the excrement sampling detection device, about 10-20 times, so that the excrement sample and the sample diluent are in full contact and form a mixed solution.
[0066] 5, pull the limiting assembly 300 from the sampling assembly 200.
[0067] 6, the protruding part 310 of the limiting assembly 300 is embedded in the groove 133 of the rotating assembly 130, the limiting assembly 300 is driven to rotate the rotating assembly 130 by 90°, and the rotating assembly 130 is adjusted from the first state to the second state, at this time, the mixed solution in the upper part 111 of the first pipe body can flow into the second pipe body 120 through the filter assembly in the hollow channel 131 of the rotating assembly 130, and then flow into the second pipe body 120 through the slope structure 140.
[0068] 7, push the cap 210 towards the first pipe body 110, at this time, due to the sealing effect of the sealing assembly 211, the space of the upper part 111 of the first pipe body is compressed, the internal pressure rises, thereby accelerating the filtering speed of the mixed solution in the upper part 111 of the first pipe body, so that more filtered liquid flows into the second pipe body 120, reference Figure 8 .
[0069] 8, the liquid flowing into the second pipe body 120 contacts the test strip 400 and is absorbed by the test strip 400, and the color change of the test strip 400 is determined to determine the detection result.
[0070] The above describes the preferred embodiment of the present application in detail. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the present application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment on the basis of the prior art according to the concept of the present application shall be within the protection scope determined by the claims.
