Referring to fig. 1-8, an integrated device for sampling, diluting and detecting feces comprises a test tube 1 and a sampling rod 2, wherein a gland placing cylinder 20 with a gland 22 is arranged at the top of the sampling rod 2, and the gland 22 can move in the gland placing cylinder 20. A plurality of limiting protrusions 24 are horizontally arranged around the inner wall of the upper middle part of the gland 22 placing barrel and are used for initially limiting the gland 22. The bottom of the gland placement barrel 20 is provided with a limit table 21. The limiting protrusion 24 is arranged to limit and block the gland 22 initially (the initial state is the state before sampling), so that the gland 22 is prevented from moving downwards without being stressed or being touched by mistake, and the waste of test paper is avoided. The limiting bulge 24 is made of silica gel, when the gland 22 is stressed, the gland 22 can press the limiting bulge 24 to deform, and when the limiting bulge 24 is clung to the inner wall of the gland placing cylinder, the gland 22 can be stressed to move downwards without blocking. (the limiting protrusion 24 may also be made of a plastic material, such as PVC, which is easily broken, when the pressing cover 22 is stressed, the pressing cover 22 may press the limiting protrusion 24 to be broken, and the pressing cover 22 may be forced to move downwards when losing the blocking. The setting of spacing platform 21 is used for spacing gland 22, prevents gland 22 downwardly moving displacement too big, avoids soaking test paper 32 in the liquid that awaits measuring and leads to unable detection.

The bottom of gland 22 sets up the first test paper shell draw-in groove 23 that is used for joint test paper card shell 3, and the inside of sampling rod 2 is provided with the second test paper shell draw-in groove 29 of placing test paper card shell 3. In the initial state, the top of the test paper clamping shell 3 is clamped in the first test paper clamping groove 23, and the middle lower part of the test paper clamping shell 3 is clamped in the second test paper clamping groove 29.

The test paper clamping shell 3 is provided with a test paper clamping groove 31 for clamping the test paper 32, the bottom of the test paper clamping shell 3 is provided with a sealing ring groove 33, and a sealing ring 34 is clamped on the sealing ring groove 33; the bottom of the sampling rod 2 is provided with a sealing cavity 28, and a sealing ring 34 is matched with the sealing cavity 28, so that the reagent in the reagent storage cavity 11 cannot flow into or infiltrate into the sampling rod 2 in an initial state.

An external thread 25 is arranged at the top of the sampling rod 2 and positioned at the bottom of the gland placing cylinder 20, and an internal thread 14 matched with the external thread 25 is arranged at the top of the test tube 1; the external thread 25 and the internal thread 14 are used for screwing the sampling rod 2 and the test tube 1, while avoiding the outflow of reagents at the top of the test tube 1.

The outer wall of the sampling rod 2 is provided with an observation port 27, and the observation port 27 is opposite to the display part of the detection test paper 32. The viewing port 27 is not open, but is a thin transparent window of plastic material to prevent reagent from penetrating into the test strip at the reagent storage chamber 11 when the test tube 1 is shaken in an initial state or after use.

The bottom end of the sampling rod 2 is provided with a sampling thread 26 for taking up the attached sample.

The test tube 1 is composed of a reagent storage cavity 11, a neck observation cavity 12 and an excessive sample storage cavity 13 from top to bottom, wherein the neck observation cavity 12 is respectively communicated with the reagent storage cavity 11 and the excessive sample storage cavity 13. The neck observation cavity 12 is thinner than the redundant sample storage cavity 13, and the outer diameter of the sampling rod 2 is slightly smaller than the inner diameter of the neck observation cavity 12, so that the sampling rod 2 can be just inserted into and withdrawn from the neck observation cavity 12. On the one hand, the color change at the 2ct of the test strip 3 is easy to observe, and on the other hand, the redundant sample can be scraped off in the redundant sample storage cavity 13. The connection parts of the reagent storage cavity 11 and the neck observation cavity 12 and the connection parts of the neck observation cavity 12 and the outer wall of the redundant sample storage cavity 13 are in cambered surface design. The design of the cambered surface can lead the outer surface of the test tube 1 to be smooth, and improves the comfort of people taking.

Working principle: when in use, the sampling rod 2 is screwed out of the test tube 1, and the sampling thread 26 at the bottom of the sampling rod 2 is inserted into a sample to be tested for a plurality of times, so that the sample occupies the excrement; the sampling rod 2 is then inserted into the test tube 1, and the sampling rod 2 is screwed by the external thread 25 and the internal thread 14; then holding the test tube 1 for 10-20s to shake continuously for the excrement and urine can be mixed evenly with the reagent in the test tube 1, then pressing the gland 22 downwards by hand, the gland 22 moves downwards through the limiting boss 24 until the gland 22 reaches the limiting table 21 at the bottom of the gland placing cylinder 20, the test paper clamping shell 3 moves downwards to push out the sealing ring 34 from the sealing cavity 28 in the downward movement process of the gland 22, at the moment, the test paper clamping shell 3 and the sampling rod 2 form a certain gap, and the reagent with a sample to be tested can enter the sampling rod 2 and contact with the bottom of the detection test paper 32. After standing for a while, the color of the test paper 32CT can be observed from the neck opening observation cavity 12 of the test tube 1, the operation is simple, and the detection convenience is improved.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
