Description

Technical Field

[0001] The utility model relates to the field of liquid secretion detection, and more specifically, it relates to a liquid secretion detection device. Background Art

[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 method for the preliminary screening of suspicious populations. However, since the urine detection sampling process involves privacy and cannot be carried out face-to-face, the samples are easily faked; and 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pathway is long, and it is easily interfered by the metabolism of other substances in the body and has gradually been replaced by saliva detection that has emerged in recent years. 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 is of great significance for the detection of abused drugs.

[0003] Currently, the saliva detection kits that are more widely used in the market are mostly in the form of separation of detection cards and saliva collectors. Most of these saliva detection kits use saliva collectors to collect samples and then squeeze and drop them onto the detection cards for detection, and cannot achieve the integration of saliva collection and detection.

[0004] Chinese Patent CN204613216U provides a saliva detection kit for abused drugs, which includes a saliva collector. The saliva collector includes a hand-held end at the end, a saliva collection part at the bottom, and a saliva detection part in the middle. The hand-held end and the saliva detection part are plastic cardboards that are buckled up and down. The saliva detection part is internally provided with a detection test strip and an observation window; a saliva storage cover, the saliva storage cover includes a cover opening, a cover body, a cover bottom, and a support frame. Among them, the inside of the cover opening, the cover body, and the cover bottom constitutes a saliva collection cavity, and a sampling hole is provided on the side of the cover body; a collector protection cover, and this protection cover buckles the saliva collector through concave and convex holes.

[0005] This kit is a detection kit that integrates saliva collection, saliva detection, and saliva storage. From the sampling process to the detection process, and even the process of sending the sample for inspection, it is not contaminated throughout the process, and there is no need to repeatedly sample, avoiding sample differences caused by different stages of drug abuse metabolism in human saliva at different times, and is suitable for the preliminary screening work of quickly qualitatively detecting suspicious drug addicts on-site.

[0006] The end of the saliva collection part in this kit is a sponge head. When drug addicts are tested, it is very easy to bite and swallow the sponge head, resulting in difficulties in the test. Summary of the Utility Model

[0025] Embodiment 1

[0026] As Figure 1-2As shown in the figure, it is the basic structure of Embodiment 1 of the present utility model. This embodiment 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 first limiting block 11, a rod body 12 and a second limiting block 13. The bracket 3 includes a frame body 31 and a limiting body 32. The frame body 31 is provided with a guiding groove 311 and a detection groove 312. The rod body 12 passes through the sponge 2 and is inserted into the guiding groove 311. The first limiting block 11 and the second limiting block 13 are respectively fixed at both ends of the rod body 12. The first limiting block 11 is located on the side of the sponge 2 away from the frame body 31 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 second limiting block 13 linearly slides in the guiding groove 311. The limiting body 32 is fixed on the frame body 31, and the limiting body 32 is located between the second limiting block 13 and the sponge 2. The notch of the guiding groove 311 and the notch of the detection groove 312 are both located on the side of the frame body 31 close to the sponge 2, and both notches are in contact with the sponge 2. The test strip 4 is fixed in the detection groove 312. The groove wall of the detection groove 312 is transparent.

[0027] When using this device, the subject needs to bite the sponge 2 first. After the sponge 2 is fully soaked with the subject's saliva, the tester takes out this device from the subject's mouth, presses the first limiting block 11 against a certain plane, and moves the frame body 31 in the direction close to the first limiting block 11 to compress the sponge 2 to squeeze the saliva in the sponge 2 into the detection groove 312 to soak the test strip 4. After the test strip 4 detects the target substance in the saliva, the pattern or color changes. The detection result of the test strip 4 is presented in front of the tester through the transparent groove wall of the detection groove 312. From the sampling process to the detection process, and even the whole process of sending for inspection of this device is not contaminated, and there is no need to repeat sampling multiple times. This device inserts a rod body 12 that is difficult to bite off in the sponge 2. Blocked by the rod body 12, it is difficult for the subject to bite and swallow the sponge 2, enabling the saliva test to proceed smoothly.

[0028] Specifically, the sponge 2 is a polyolefin fiber sponge with high tensile strength.

[0029] Specifically, one end of the test strip 4 close to the sponge 2 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.

[0030] Specifically, each point on the end surface of the sponge 2 close to the frame body 31 is in contact with the frame body 31, increasing the contact area between the frame body 31 and the sponge 2 to facilitate squeezing out as much saliva as possible for testing.

[0031] Specifically, a through hole is provided on the limiting body 32, the rod body 12 is in the through hole, the axis of the rod body 12 is collinear with the axis of the through hole, and the hole wall of the through hole is in contact with the rod body 12 to assist in defining the moving direction of the rod body 12 on the bracket 3. The second limiting block 13 is collinear with the axis of the guiding groove 311, and the groove wall of the guiding groove 311 parallel to its own axis is in contact with the second limiting block 13 to define the sliding direction of the limiting block in the guiding groove 311.

[0032] Specifically, the second limiting block 13 is collinear with the axis of the rod body 12, the second limiting block 13 is conical, and the flat surface of the second limiting block 13 is fixedly connected to the end surface of the rod body 12. The conical surface of the second limiting block 13 helps to guide the elastic deformation of the limiting body 32, so that the second limiting block 13 can smoothly pass through the through hole.

[0033] In this embodiment, the first limiting block 11, the rod body 12 and the second limiting block 13 are integrally formed. The fixing column 1 in this embodiment is a plastic fixing column, and the fixing column 1 is transparent throughout. The axes of the first limiting block 11, the rod body 12 and the second limiting block 13 are collinear.

[0034] Specifically, the foam 2 and the frame body 31 are fixedly connected to further reduce the possibility of the foam 2 detaching from the end of the rod body 12 away from the frame body 31.

[0035] Specifically, the bracket 3 further includes a liquid blocking ring 33. The liquid blocking ring 33 is fixedly connected to the frame body 31, and the liquid blocking ring 33 is sleeved on the end of the foam 2. The liquid blocking ring 33 can limit saliva inside the liquid blocking ring 33 as much as possible when the foam 2 is compressed, so as to increase the amount of saliva in the detection groove 312, help the test strip 4 absorb more saliva, and improve the accuracy of saliva detection. Preferably, when the distance between the first limiting body 32 and the frame body 31 is the shortest, the end surface of the liquid blocking ring 33 away from the frame body 31 is flush with the point on the first frame body 31 that is farthest from the first limiting body 32, so that when the foam 2 is compressed to the minimum, all the foam 2 is located inside the liquid blocking ring 33, reducing the waste of saliva.

[0036] In this embodiment, the liquid blocking ring 33, the frame body 31 and the limiting body 32 are integrally formed, and the bracket 3 is a rigid bracket 3.

[0037] This embodiment further includes a handle 5, and the handle 5 is fixed on the side of the frame body 31 away from the foam 2.

[0038] In summary, in the present device, the fixing posts 1 that are difficult to bite through are inserted into the foam 2. The relative linear movement between the fixing posts 1 and the bracket 3 squeezes the saliva in the foam 2 onto the test strip 4 in the bracket 3. From the sampling process to the detection process, and even during the process of sending the sample for inspection, the whole process is not contaminated, and there is no need to repeatedly sample. Blocked by the rod body 12, the subject will have difficulty biting and swallowing the foam 2, enabling the saliva test to proceed smoothly.

[0039] Embodiment 2

[0040] As Figure 3 shown, the difference between this embodiment and Embodiment 1 is that the second limiting block 13 is collinear with the axis of the rod body 12, the second limiting block 13 is hemispherical, and the plane of the second limiting block 13 is fixedly connected to the end face of the rod body 12. When the fixing post 1 is connected to the bracket 3, one side of the second limiting block 13 first passes through the limiting body 32. By applying pressure to the second limiting block 13, under the guidance of the spherical surface of the second limiting block 13, the limiting body 32 elastically deforms, enabling the second limiting block 13 to smoothly pass through the through hole entirely.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
