Description

Technical Field

[0001] The present invention particularly relates to a detection device. Background Art

[0002] In order to combat drug abuse, a social problem, drug testing is performed in various industries such as employment, education, sports, law enforcement, and medical care. Drug testing usually requires collecting test samples first and then conducting tests.

[0003] At present, the detection of samples on the market is generally carried out by using test strips for instant detection, which can quickly obtain the test results. The test results may be positive, negative or invalid. This detection method is simple, low-cost and easy to operate, but it has some disadvantages, such as (1) compared with the precise laboratory test, the test results of the instant test strips are less accurate and unreliable; false positive, false negative or invalid results may occur, even if the best quality test strips are used. The above phenomenon may occur because the sample is dirty, the chemical substances used are deteriorated, or the conditions of the sample itself are not suitable for instant detection; (2) when a positive result appears, the sample provider will usually argue that the sample is not theirs. They require proof that the sample is theirs, which requires DNA testing. However, DNA testing requires re-collecting the sample because the original sample may be deteriorated or contaminated and is not suitable for DNA testing. However, the re-collected sample is not the same as the previous sample, and the sample provider will not be convinced, which will lead to continued arguments.

[0004] There is another detection method, which is not to test the sample immediately, but to collect the sample using a sample collection device, and then send the sample to a laboratory for testing in the laboratory. This detection method cannot quickly obtain preliminary test results.

[0005] Another detection method is to first use a test strip for instant testing. When a false positive occurs, a sample is collected and sent to a laboratory for confirmation testing. Laboratory testing is usually more accurate, and laboratory testing can perform quantitative testing to give the content of drugs of abuse in the sample. However, this detection method requires the collection of samples again. The recollected sample is not the same sample as the previous sample, and the recollection and testing process of the sample requires a series of supervision and monitoring. The collector also needs to honestly and reliably confirm the identity of the sample provider, avoid mistakes, and avoid mistaking or confusing the identity of the sample provider. During the transportation of the sample to the laboratory and the testing of the sample in the laboratory, ensure that the sample is not damaged or contaminated.

[0006] Currently, some testing devices, after obtaining initial results, do not allow for storage of collected samples for later use in confirmatory testing or DNA testing. Many other sample collection and testing devices make it difficult to extract samples from the device for secondary testing. Still other testing devices are very complex in their design and manufacturing and require the use of relatively expensive materials. Summary of the invention

[0045] In some preferred embodiments, a second channel is provided in the cup body 5 for the locking element 6 to move. Figure 3 , 5 As shown, the second channel is located between the first cavity 1 and the second cavity 2, and between the third cavity 3 and the fourth cavity 4. In some preferred embodiments, one end of the second channel is closed, and the other end has an entrance 13 to allow the locking element 6 to enter. In some preferred embodiments, as Figure 3-5As shown, the end where the second channel is closed is provided with a base 14, which is configured to place and fix the buffer reagent holding device. In some preferred embodiments, the buffer reagent holding device does not have a fixed shape. When filled with the buffer reagent, it has a certain shape, and this shape can be changed; when the buffer reagent is released, the shape of the buffer reagent holding device changes. The buffer reagent holding device can be a capsule or a bag that can store the buffer reagent. After the buffer reagent is loaded, the buffer reagent holding device is placed in the base 14, and the base 14 can fix the buffer reagent holding device. In some preferred embodiments, the base is configured to be used to hold the buffer reagent, and the buffer reagent is enclosed in the base. In some preferred embodiments, the open end on the base is closed by a third sealing layer, so that the buffer reagent is enclosed in the base. In some preferred embodiments, the buffer reagent can be a diluent or a solution that reduces the viscosity of the liquid sample or other functional reagent; for example, some samples cannot be tested in their original state, or the test results are not ideal, and usually require pretreatment to change their physical or chemical properties, for example, using a buffer solution to help dilute or buffer these samples before testing.

[0046] In some preferred embodiments, the buffer reagent holding device is provided with an opening, which is sealed and can be opened. In other preferred embodiments, the buffer reagent holding device may not be provided with an opening, for example, the buffer reagent holding device is a capsule or bag capable of storing the buffer reagent, and any part of the capsule or bag can be punctured to allow the buffer reagent to flow out.

[0047] In some preferred embodiments, a positioning groove 15 is provided in the second channel to facilitate the insertion of the locking element 6 into the second channel. Figure 1-2 As shown, in this embodiment, the positioning grooves 15 are arranged on two opposite sides of the second channel, which is conducive to the locking element 6 entering the channel.

[0048] In some preferred embodiments, Figure 4 As shown, a positioning convex strip 16 is provided on the side of the locking element 6, and the positioning convex strip 16 matches the positioning groove 15. The positioning convex strip 16 can enter the positioning groove 15 and can slide along the positioning groove 15.

[0049] In some preferred embodiments, Figure 3-5As shown, the locking element 6 is provided with a through hole 17, and the through hole 17 can connect the first cavity 1 and the second cavity 2. When the through hole 17 corresponds to the first opening 7 and the second opening 8, the first cavity 1 is connected with the second cavity 2, and the liquid in the first cavity 1 can flow into the second cavity 2 through the through hole 17. When the through hole 17 has no overlapping part with the first opening 7 and the second opening 8, the first opening 7 and the second opening 8 are blocked by the locking element 6, the communication between the first cavity 1 and the second cavity 2 is cut off, the liquid sample cannot enter from the first cavity 1 into the second cavity 2, and the second cavity 2 is closed, and a certain volume of sample can be stored and preserved.

[0050] In some preferred embodiments, Figure 3-5 As shown, one end of the locking element 6 is provided with a pointed end 18, which is configured to pierce the buffer reagent containing device or pierce the opening on the buffer reagent containing device or pierce the third sealing layer, so that the buffer reagent can flow out.

[0051] In some preferred embodiments, Figure 1-5 As shown, the device further comprises a cup cover 19, which can cover the cup body 5. In some preferred embodiments, Figure 3-5 As shown, the upper surface of the cup cover 19 extends out of the four side walls. The side walls of the cup cover 19 are made of semi-flexible material, which can be pressed and can also rebound automatically. Pressing the side walls inward is conducive to inserting the side walls of the cup cover 19 into the cup body 5. After inserting the cup body 5, the side walls rebound and cling to the inner wall of the cup body 5. In this way, after the cup cover 19 covers the cup body 5, the cup body 5 can be sealed, and the whole device has good airtightness and will not leak. In some preferred embodiments, such as Figure 3-5 As shown, a connecting column 20 is fixedly provided on the lower surface of the cup cover 19 , and the connecting column 20 is fixedly connected to the cup cover 19 .

[0052] In some preferred embodiments, the device further comprises a collection element 21, which can collect or release liquid samples. The collection element 21 is fixedly connected to the cup cover 19, so that the collection element 21 can collect, transfer, and release samples. The collection element 21 can be operated by holding the cup cover 19, and finally the collection, transfer, and release of samples can be achieved. In some preferred embodiments, such as Figure 3 , 5As shown, the collecting element 21 is fixedly connected to the connecting post 20 on the cup cover 19. The collecting element 21 can be glued or welded to the connecting post 20 by sealant, hot melt adhesive or other glue, or can be connected to the connecting post 20 by any suitable method. In other preferred embodiments, the collecting element 21 is detachably connected to the cup cover 19. In some preferred embodiments, the collecting element 21 is compressible, for example, a compressible collecting element 21 is used to absorb the liquid sample, and then the collecting element 21 is squeezed to release the sample. Compressibility refers to the material property that the shape of the material can be deformed by mechanical pressure so that the liquid can be squeezed out of the material when the material retains the liquid. The collecting element 21 can be made of any material that absorbs and retains liquid. In some embodiments, the collecting element 21 is a sponge, but in other embodiments, it can be non-woven fabric, absorbent paper, nylon, cotton or any other material that can absorb and retain liquid. When the material of the collecting element 21 is a sponge, it can be natural or synthetic. In the embodiment shown, as Figure 3-5 As shown, the collection element 21 is a cylindrical sponge material suitable for being placed in the mouth of the subject to collect saliva. However, in other embodiments, the collection element 21 can be any suitable and convenient shape. In a specific embodiment, the collection element 21 is treated with a chemical component (such as citrate or other chemicals) to promote saliva secretion and facilitate absorption by the collection element 21.

[0053] In some preferred embodiments, the first channel 22 can receive and hold the collection element 21, and is used in conjunction with the collection element 21. In some preferred embodiments, the first channel 22 is vertically arranged with the second channel. In some preferred embodiments, the first channel 22 is located between the first cavity 1 and the third cavity 3. In some preferred embodiments, a protrusion 23 is arranged in the cup body 5, and is configured to squeeze the collection element 21 and release the sample. In some preferred embodiments, the protrusion 23 is located above the second channel. In some preferred embodiments, the protrusion 23 is located directly below the first channel 22. A portion of the protrusion 23 extends into the first channel 22. There is no seal between the protrusion 23 and the first channel 22, but a clearance space is left, so that the liquid sample can flow out from the clearance space. When in use, pick up the cup cover 19, use the collection element 21 to collect the sample, then insert the collection element 21 into the first channel 22, move the collection element 21 downward so that it contacts the protrusion 23, and continue to move the collection element 21 downward. The collection element 21 is squeezed by the protrusion 23 to release the sample, and the sample is divided into two parts, which flow to the first cavity 1 and the third cavity 3 respectively.

[0054] In some preferred embodiments, the protrusion 23 is a dome-shaped protrusion 23 . The protrusion 23 may also be other suitable shapes, so that the collection element 21 can contact the protrusion 23 and be squeezed to release the sample, and the sample can flow smoothly to the first cavity 1 and the third cavity 3 .

[0055] In some preferred embodiments, a sealing ring is installed at the front end of the locking element 6, and the sealing ring plays a sealing role so that the liquid sample cannot flow from the gap to other places.

[0056] The present invention also provides a method for using the detection device, comprising the following steps: Figure 1-5 , the sample is a saliva sample for description)

[0057] (1) placing the collection element 21 in the user's mouth, and the collection element 21 continuously absorbs saliva or collects saliva samples in other ways;

[0058] (2) Then, the collecting element 21 is inserted into the first channel 22, and the collecting element 21 is moved downward so that it contacts the protrusion 23. The collecting element 21 is further moved downward, and the collecting element 21 is squeezed by the protrusion 23 to release the sample. The sample is divided into two parts and flows to the first chamber 1 and the third chamber 3 respectively. The sample passes through the first opening 7 of the first chamber 1, passes through the second channel, and flows into the second chamber 2. At the same time, the sample in the third chamber 3 passes through the third opening 9, passes through the second channel, and flows to the fourth chamber 4. The sample is stored in the second chamber 2 and the fourth chamber 4.

[0059] (3) After a certain volume of sample is collected in the second chamber 2 and the fourth chamber 4 respectively (the sample can be used for laboratory confirmation testing or DNA testing or other testing), the locking element 6 is inserted into the second channel (the locking element 6 is inserted into the second channel, such as Figure 5 As shown, this step can also be performed in step (2), the locking element 6 is pushed inwardly, so that the locking element 6 slides inwardly along the positioning groove 15, and the opening 17 is connected with the first opening 7 and the second opening 8 at the same time, and the liquid sample can enter the second cavity 2 from the first cavity 1. At this time, the third cavity 3 and the fourth cavity 4 are in a connected state, as shown in FIG. Figure 5 As shown, the liquid sample can enter the fourth cavity 4 from the third cavity 3; the locking element 6 is pushed inwardly continuously, when the first opening 7 and the second opening 8 cannot be connected to the opening at the same time (i.e., when the first opening 7 is connected to the opening, the second opening 8 is not connected to the opening or when the second opening 8 is connected to the opening, the first opening 7 is not connected to the opening), the connection between the first cavity 1 and the second cavity 2 is cut off, and the liquid sample cannot enter the second cavity 2 from the first cavity 1; the locking element 6 is pushed inwardly continuously, and the tip of the locking element 6 enters the base 14, and finally the tip 18 of the locking element 6 pierces the buffer reagent holding device or pierces the third sealing layer ( Figure 3 The buffer reagent containing device and the third sealing layer are not shown in the figure), the buffer reagent flows out, and the buffer reagent can enter the fourth chamber 4, and continue to push the locking element 6 inward until the locking element 6 can no longer move inward. Figure 3 As shown ( Figure 3The sealing ring is not shown in the figure), at this time, the sealing element seals the gap, the connection between the third chamber 3 and the second channel is cut off, the connection between the fourth chamber 3 and the second channel is cut off, and the connection between the third chamber 3 and the fourth chamber 4 is cut off. A certain volume of sample (this sample also includes a buffer reagent) is stored in the fourth chamber 4, and the sample stored in the second chamber 2 and the fourth chamber 4 can be used for secondary confirmation detection or for detection for other purposes. After the connection between the first chamber 1 and the second chamber 2 is cut off, and the connection between the third chamber 3 and the fourth chamber 4 is cut off, the samples flow into the first chamber 1 and the third chamber 3 respectively, and are stored in the two chambers respectively; if a test strip is provided in the third chamber 3, then the detection of certain substances in the sample can be realized in the third chamber 3. Similarly, if a test strip is provided in the first chamber 1, then the detection of certain substances in the sample can be realized in the first chamber 1.

[0060] In the present embodiment, the liquid sample can be a saliva sample, and a test strip can be placed in the first cavity 1 or / and the third cavity 3, and these test strips can detect abused substances, such as cocaine, amphetamines, sedatives, etc., in real time, and give a preliminary test result. A certain amount of samples are stored in the second cavity 2 and the fourth cavity 4, and they can be used for secondary confirmation detection or for DNA detection or for the detection of other substances. The device of the present invention can not only perform real-time detection of abused drugs in the sample, can be sent to a laboratory for secondary confirmation detection, but also can be used for DNA detection to confirm the sample provider, and the above-mentioned test samples are all from the same sample, ensuring the accuracy of the results, reducing mistakes, and using this device to detect abused drugs, which is simple to operate and has high accuracy.
