[0002] The abuse of addictive substances has currently become a public health problem and a social problem worldwide. The detection of abused drugs at home and abroad mostly uses biological specimens such as blood, urine, saliva, and hair. Among them, urine detection is the most commonly used means for the preliminary screening of suspicious populations. However, due to the privacy involved in the urine detection sampling process, it cannot be carried out face to face, and the sample is easily faked; moreover, the in vivo metabolic pathway is long, and it is easily interfered by the metabolism of other substances in the body and has gradually been replaced by the recently emerging saliva detection. Saliva detection can be sampled face to face, is not easy to fake, and can be detected within a short time after drug abuse, which has important significance for the detection of abused drugs.

[0003] At present, the saliva detection kits that are more widely used in the market are mostly in the form of separation between the detection card and the saliva collector.

[0030] As Figure 1 , Figure 2As shown in the figure, the utility model provides a liquid secretion detection device, which includes a fixing column 1, a sponge 2, a bracket 3 and a test strip 4. The fixing column 1 includes a holding cover 11, a rod body 12 and a limiting block 13 which are integrally connected. The holding cover 11 and the limiting block 13 are respectively connected to both ends of the rod body 12. The bracket 3 includes a frame body 31, a limiting body 32 and a liquid blocking ring 33 which are integrally formed. One side wall of the limiting body 32 is integrally connected to the frame body 31, and the other side wall of the limiting body 32 is integrally connected to the liquid blocking ring 33. The liquid blocking ring 33 is coaxially arranged with the limiting body 32, and the liquid blocking ring 33 is arranged at the outer end of the side wall of the limiting body 32. A placing groove 311 is arranged inside the frame body 31. The placing groove 311 extends along the length direction of the frame body 31, and the placing groove 311 extends into the limiting body 32. The placing groove 311 communicates with the outside of the limiting body 32, and the test strip 4 is placed inside the placing groove 311. The rod body 12 passes through the sponge 2 and also passes through the limiting body 32. The holding cover 11 is located at the end of the sponge 2 away from the frame body 31. The holding cover 11 is used to prevent the sponge 2 from detaching from the rod body 12 at the end of the rod body 12 away from the frame body 31. The liquid blocking ring 33 is sleeved on the end of the sponge 2. The limiting body 32 is located between the sponge 2 and the limiting block 13. After the test strip 4 extends out of the placing groove 311, it is inserted into the sponge 2 to increase the contact area between the test strip 4 and the sponge 2, help the test strip 4 absorb more saliva, and improve the detection accuracy.

[0031] As Figure 3 , Figure 4 shown in the figure, a guiding groove 321 and a mounting groove 322 are arranged on the limiting body 32. The guiding groove 321 communicates with the mounting groove 322, and the guiding groove 321 is located between the mounting groove 322 and the placing groove 311. The rod body 12 passes through the guiding groove 321, and the rod body 12 is slidably connected in the guiding groove 321. The side wall of the rod body 12 contacts the side wall of the guiding groove 321. The width of the mounting groove 322 is greater than the width of the guiding groove 321. The width of the limiting block 13 is greater than the width of the rod body 12. The size of the limiting block 13 is adapted to the size of the mounting groove 322. When the fixing column 1 and the bracket 3 are installed, the limiting block 13 passes through the mounting groove 322. When the limiting block 13 completely extends out of the mounting groove 322, the fixing column 1 moves downward to move the rod body 12 into the guiding groove 321. The limiting block 13 is used to prevent the rod body 12 from completely sliding out of the guiding groove 321.

[0032] The notch of the placing groove 311 is located at the end of the frame body 31 close to the sponge 2. The notch of the placing groove 311 contacts the sponge 2. A fillet 312 is arranged at the notch of the placing groove 311 to facilitate saliva to easily enter the placing groove 311 to contact the test strip 4. The notches of the guiding groove 321 and the mounting groove 322 on the side close to the sponge 2 contact the sponge 2. A protrusion 323 is arranged at the notches on this side of the guiding groove 321 and the mounting groove 322. The protrusion 323 is arranged to ensure that saliva is not easily introduced into the guiding groove 321 and the mounting groove 322.

[0033] The frame 31 is made of transparent PC material, which is convenient for observing the test results of the test strip 4.

[0034] The foam 2 is made of polyolefin fiber material and has high tensile strength.

[0035] The fixing column 1 is transparent throughout, and the fixing column 1 is a plastic fixing column 1. The bracket 3 is made of a hard material.

[0036] Each point on the end face of the foam 2 close to the frame 31 is in contact with the frame 31, increasing the contact area between the frame 31 and the foam 2, so as to facilitate squeezing out as much saliva as possible for testing. Further, the foam 2 is fixedly connected to the side wall of the limiting body 32 away from the frame 31, further reducing the possibility of the foam 2 detaching from the rod body 12 at the end of the rod body 12 away from the frame 31.

[0037] A liquid retaining ring 33 is provided to limit the saliva inside the liquid retaining ring 33 as much as possible when the foam 2 is compressed, so as to increase the amount of saliva in the placement groove 311, help the test strip 4 absorb more saliva, and improve the accuracy of saliva detection; when the distance between the frame 31 and the retaining cover 11 is the shortest, the end face of the liquid retaining ring 33 away from the frame 31 is flush with the end face of the retaining cover 11 close to the frame 31, so that when the foam 2 is compressed to the minimum, the foam 2 is completely compressed inside the liquid retaining ring 33, reducing the waste of saliva.

[0038] The retaining cover 11 is located outside the end of the foam 2 away from the frame 31; or; the retaining cover 11 is embedded in the end of the foam 2 away from the frame 31, and the end of the foam 2 away from the frame 31 slightly protrudes from the retaining cover 11, which can give users a good test experience. The retaining cover 11 is made of PC plastic material or TPE soft rubber material.

[0039] A handle 5 is fixedly connected to one end of the frame 31 away from the limiting body 32.

[0040] The working principle of the liquid secretion detection device provided by the present utility model: The subject needs to bite the foam 2 first. After the foam 2 is fully soaked by the saliva or secretion of the subject, the tester takes out the device from the subject's mouth, presses the retaining cover 11 against a certain plane, holds the handle 5, and moves the frame 31 in the direction close to the retaining cover 11 to compress the foam 2 to squeeze out the saliva or secretion in the foam 2 into the placement groove 311 to soak the test strip 4. After the test strip 4 detects the target substance in the saliva or secretion, the pattern or color changes, and the test result of the test strip 4 is presented in front of the tester through the transparent frame 31.

[0041] From the sampling process to the detection process, and even the process of sending for inspection, the present utility model is not contaminated throughout the process, and there is no need to repeat sampling multiple times. A rod body 12 that is difficult to bite off is inserted into the foam 2. Under the block of the rod body 12, it is difficult for the subject to bite and swallow the foam 2, enabling the saliva and secretion tests to proceed smoothly.

[0042] Example 2

[0043] The difference between this embodiment and Embodiment 1 is that: as Figure 5 shown, only a guiding groove 321 is provided on the limiting body 32. The cross-section of the limiting block 13 in the horizontal direction is semi-circular. The rod body 12 is connected to the center position of the left side wall of the limiting block 13. The width of the rod body 12 is smaller than the diameter of the limiting block 13. Two baffles 6 are integrally connected to the upper wall of the frame body 31. The two baffles 6 are both perpendicular to the upper wall of the frame body 31. The two baffles 6 and the upper wall of the frame body 31 enclose a sliding groove 7. The limiting block 13 moves in the sliding groove 7.

[0044] The limiting block 13 extends into the guiding groove 321 from the side of the guiding groove 321 close to the liquid blocking ring 33. The arc surface of the limiting block 13 abuts against the limiting groove. Push the limiting block 13 forcefully in the direction close to the handle 5. The limiting block 13 extends out of the guiding groove 321 and is slidably connected inside the sliding groove 7.
