Description
Technical Field
[0001] The utility model relates to the field of drug detection, in particular to a portable sweat sampling box. Background Art
[0002] In the daily public security management activities of the police, it is often necessary to take samples from specific groups of people to obtain test materials for biochemical testing, so as to screen out drug users for public security punishment. Common testing methods mainly include blood testing, hair testing and sweat testing. For blood testing, since drug users are often a high-risk group for infectious diseases, blood testing sampling is highly invasive and may cause the sampling personnel to be infected with the disease. For hair testing, since the residual amount of drug components in human hair is low, precision instruments are required for testing, which makes the testing cost high. For sweat testing, sweat sampling is less invasive and can reduce the risk of sampling personnel contracting diseases. In addition, sweat carries a variety of biological molecules such as electrolytes, metabolites, hormones, and larger proteins, and is not easily interfered by factors such as diet. It can be tested without the use of precision instruments, and the testing cost is low.
[0003] In the related art, during the sweat sampling process, it is necessary to clean the sampling area of the person to be tested, then stimulate the sampling area to make it sweat and sample the sweat, and finally store the sampled sweat sample in a low temperature environment of minus 20°C for preservation and send it to the laboratory for biochemical testing. In the above process, a large number of sampling tools are required to assist the operation, such as alcohol cleaning tablets, sweat stimulation tablets, sweat patches, cotton swabs, protective gloves, etc. Sampling personnel who have not received professional training are very likely to forget to bring some sampling tools, resulting in failure to sample normally. In addition, the strict requirements of sweat for the storage environment temperature also make it easy for sweat to denature during storage and transportation, thereby affecting the biochemical test results.
[0004] Therefore, a portable sweat sampling box is urgently needed to solve the above problems. Utility Model Content

[0041] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.
[0042] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0043] Figure 1 It shows a schematic structural diagram of the portable sweat sampling box provided by the utility model in a closed state. Figure 2 The schematic diagram of the structure of the portable sweat sampling box provided by the utility model in the open state is shown. Figure 1 to Figure 2 As shown, the portable sweat sampling box includes a box body 1, a box cover 2, a sampling tool assembly 4 and a sample protection assembly 5. The box body 1 with a receiving cavity 3 and the box cover 2 are rotatably connected together by hinges, and can be buckled to close the receiving cavity 3. The receiving cavity 3 can accommodate the sampling tool assembly 4 using the sweat obtained by sampling as the sample material and the sample protection assembly 5 for storing and transporting the sweat sample material. It can be understood that in other embodiments, the box body 1 and the box cover 2 can also be pivotally connected in other ways, which are not limited here.
[0044] Continue as Figure 1 to Figure 2 As shown, the accommodating chamber 3 has a sampling tool storage chamber 31 and a sample storage chamber 32 which are independently arranged. The sampling tool storage chamber 31 can accommodate the sampling tool combination 4, and the sample storage chamber 32 can accommodate the sample protection combination 5. The sampling tool combination 4 and the sample protection combination 5 are separated from each other and placed separately, thereby dividing the functional areas. When the sampling tool combination 4 is used to sample sweat, it does not hinder the sample protection combination 5 from storing sweat samples normally.
[0045] Figure 3 The schematic diagram of the structure of the portable sweat sampling box provided by the utility model in the decomposed state is shown. Figure 3 Combination Figure 2As shown, the sampling tool combination 4 placed in the sampling tool storage cavity 31 has various sampling tools required for sampling sweat as a test material, for example, including an alcohol cleaning sheet 41 for wiping and cleaning the sampling site of the person to be tested to prevent the sampled sweat test material from being mixed with impurities and affecting the biochemical experiment test results; also including a sweat stimulation sheet 42 for inducing sweating at the sampling site of the person to be tested; also including a sweat patch 43 for collecting sweat discharged from the palm side of the forearm of the person to be tested; also including a cotton swab 44 for collecting sweat discharged from the palm of the person to be tested; also including protective gloves 45, the sampling personnel wear the protective gloves 45 during the sampling process, so as to prevent the bacteria on the hands from contaminating the sweat test material and thus affecting the biochemical test results, and also prevent the pathogens that may be carried in the sweat test material from being transmitted to the sampling personnel.
[0046] The alcohol cleaning sheet 41 contains alcohol, and the sweat stimulation sheet 42 contains stimulation-inducing components, and they are sampling tools containing chemical reagents. The chemical reagents contained therein can easily cause contamination of the containing cavity 3. The sweat patch 43, cotton swab 44 and protective gloves 45 do not contain chemical reagents, and they are sampling tools that do not contain chemical reagents.
[0047] In order to reduce the influence of sampling tools containing chemical reagents on sampling tools without chemical reagents, the sampling tool storage chamber 31 has a first receiving groove 311 and a second receiving groove 312 which are independent of each other. The first receiving groove 311 is used to place sampling tools containing chemical reagents, and the second receiving groove 312 is used to place sampling tools without chemical reagents. By isolating the sampling tools containing chemical reagents from the sampling tools without chemical reagents, it is prevented that the sampling tools containing chemical reagents and the sampling tools without chemical reagents shake and contact each other during the transportation process, thereby causing the sampling tools without chemical reagents to be contaminated by chemical reagents.
[0048] After obtaining the sweat sample sampled by the sweat patch 43 or the cotton swab 44, only by properly storing it in an environment below -20°C and transporting it to the laboratory can the normal operation of the biochemical test be ensured. The high temperature environment will inevitably lead to the denaturation of various biological molecules such as electrolytes, metabolites, hormones, larger proteins, etc. in the sweat, affecting the results of the sweat biochemical test.
[0049] In order to ensure the stability of the sample, the sample protection assembly 5 includes a test tube 51 for storing sweat and a refrigeration component 52. The refrigeration component 52 is placed under the test tube 51 and can absorb heat. After the test tube 51 stores sweat, the ambient temperature around the test tube 51 is controlled below -20°C, thereby allowing the sweat sample to be within a suitable storage temperature range.
[0050] During the transportation of sweat samples, if the test tube 51 is bumped, the sweat samples stored in the test tube 51 may easily overflow. Therefore, the sample protection assembly 5 further includes a test tube rack 53, which has a groove 531 for accommodating the test tube 51. The groove 531 fixes the test tube 51 during the transportation of the sweat samples, and prevents the test tube 51 from being bumped.
[0051] In actual operation, sampling personnel often test several persons to be tested successively, so multiple test tubes 51 are needed to respectively accommodate sweat samples of different persons to be tested. In order to prevent the sweat samples from being mixed due to collisions between the multiple test tubes 51 during transportation, the number of grooves 531 is the same as the number of test tubes 51 and they are arranged in a one-to-one correspondence to prevent collisions between the multiple test tubes 51.
[0052] The box body 1 includes a box body shell 11 and a first liner 12. The first liner 12 is filled inside the box body shell 11, and the accommodating chamber 3 is opened on the first liner 12. The first liner 12 is a heat-insulating liner that can isolate or slow down the heat transfer between the inside and outside of the box to ensure that the sample is in a low temperature state. In addition, when the sampling tool storage chamber 31 is contaminated by the sample or the sampling tool, the new first liner 12 can be replaced to obtain an uncontaminated sampling tool storage chamber 31 without replacing the entire sampling box.
[0053] The box cover 2 includes a box cover shell 21 and a second liner 22. The second liner 22 is filled in the box cover shell 21. When the box cover 2 is buckled on the box body 1, the end surface of the second liner 22 fits with the end surface of the first liner 12, and finally the accommodating cavity 3 opened on the first liner 12 can be closed. The second liner 22 is an insulation block made of insulation material, which can isolate or slow down the heat transfer between the inside and outside of the box to ensure that the sample is in a low temperature state.
[0054] It can be understood that the thermal insulation material belongs to the existing technology and can be foamed polyurethane, glass wool, thermal insulation mortar sand, etc. All materials that can realize the thermal insulation function of the first inner liner 12 and the second inner liner 22 are within the protection scope of the present application. The specific type and structure of the thermal insulation material are relatively common materials and structures in this field. The specific material of any existing thermal insulation material can achieve the effect of isolating the environment around the test tube 51 of the present application from the external environment.
[0055] The second inner liner 22 also has a plurality of protrusions 221 on the end face facing the first inner liner 12, so that when the end face of the first inner liner 12 and the end face of the second inner liner 22 are in contact with each other, the protrusions 221 can press the sampling tool combination 4 and the sample protection combination 5, thereby fixing the various sampling tools and test tubes 51 in the sampling tool combination 4, and preventing the sampling tool combination 4 and the sample protection combination 5 from shaking and bumping in the accommodating chamber 3 when the sampling personnel take the portable sweat sampling box, thereby causing the sweat sample stored in the test tube 51 to overflow and the chemical reagents in the alcohol cleaning sheet 41 and the sweat stimulation sheet 42 to splash and contaminate the accommodating chamber 3.
[0056] After the sampling box is transported to the laboratory, the sweat sample stored in the test tube 51 can only be tested if the test tube 51 and the test tube rack 53 are taken out. If the test tube 51 and the test tube rack 53 are dropped, the biochemical test cannot be performed at all. Therefore, the accommodating chamber 3 also has a take-in and put-out opening 33, and the finger of the sampling personnel can be inserted into the take-in and put-out opening 33, and the test tube rack 53 can be held from the side of the test tube rack 53, so that the test tube rack 53 in the sample storage chamber 32 can be stably taken out.
[0057] Correct sample is the premise of obtaining accurate and true drug test results. To ensure that the sweat sample obtained by sampling will not be replaced during transportation to the laboratory, the sampling box also includes a safety lock 6, which includes a lock head 61 and a lock core 62. The lock head 61 is fixed on the box body 1, and the lock core 62 is fixed on the box cover 2. The lock head 61 and the lock core 62 can be buckled with each other to form a safety lock 6, thereby locking the box body 1 and the box cover 2 to prevent the sweat sample from being replaced during transportation.
[0058] In order to enable the sampling personnel to better hold the portable sweat sampling box, the box cover 2 is also provided with a handle, and the sampling box can be grasped by the handle for easy carrying.
[0059] This embodiment provides a sweat sampling method. Taking the sampling tool combination 4 and the sample protection combination 5 as an example, the drug sampling method provided by this embodiment is described:
[0060] S1. The sampling personnel use the refrigeration unit 52 to absorb the ambient heat around the test tube 51 and prepare the storage environment temperature for storing the sweat sample. The sampling personnel wipe their hands with an alcohol cleaning sheet 41 and wear protective gloves 45 to make safe preparations for drug sampling.
[0061] S2. The sampling personnel wipe and clean the sampling site of the person to be tested with an alcohol cleaning sheet 41. The sampling site includes the palm side of the forearm and the palm. One of the two is selected to prevent the sweat sample from being mixed with impurities and affecting the biochemical test results.
[0062] S3. The sampling personnel stick the sweat stimulation sheet 42 to the cleaned palm side of the forearm or the palm to induce sweat stimulation, thereby causing the palm side of the forearm or the palm to sweat.
[0063] S4. When the sweat stimulation sheet 42 is attached to the cleaned palm side of the forearm, when the palm side of the forearm is obviously flushed or slightly sweaty, the sampling personnel tears off the sweat stimulation sheet 42, and sticks the sweat patch 43 to the sweaty palm side of the forearm to collect the sweat discharged from the palm side of the forearm. When the sweat stimulation sheet 42 is attached to the cleaned palm, when the palm is obviously flushed or slightly sweaty, the sampling personnel tears off the sweat stimulation sheet 42, directly uses the cotton swab 44 to wipe the sweaty palm to collect the sweat discharged from the palm.
[0064] S5. The sampling personnel places the sweat patch 43 or cotton swab 44 that has collected sweat into the test tube 51 to complete the sampling of the sweat sample, and repeats step S2 to perform sweat sampling on all the persons to be tested in the specific population.
[0065] S6. After completing the sweat sampling of all the specific persons, the box body 1 is rotated to be buckled with the box cover 2 to complete the sweat sampling and storage.
