Description

Technical Field

[0001] The utility model relates to the field of drug monitoring, in particular to a device for adsorbing narcotic drugs. Background Art

[0002] The harm of drugs to the human body is self-evident. Drug abuse will also cause adverse social impacts. Therefore, drugs are strictly prohibited in our country. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects or problems existing in the background technology and to provide a device for adsorbing narcotic drugs, which can be placed in the flow path of various flowing water bodies, and through continuous adsorption monitoring of the components of the water body, it is possible to determine whether there are drug addicts.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The first technical solution relates to a device for adsorbing narcotic drugs, which includes a shell and at least two adsorption layers. The shell is made of hard material and is provided with a plurality of through holes so as to be suitable for water to pass through. The adsorption layers are used for adsorbing narcotic drugs in the water. The adsorption layers are nested with each other and installed in the shell.

[0006] The second technical solution is based on the first technical solution, wherein the outer surface of the shell includes a first semi-cylindrical surface and a second semi-cylindrical surface that extend in the same direction and are coaxially arranged, and on a projection surface perpendicular to the extension direction of the first semi-cylindrical surface and the second semi-cylindrical surface, the starting point and end point of the projection of the first semi-cylindrical surface and the second semi-cylindrical surface are both located on the same straight line.

[0007] The third technical solution is based on the first technical solution, wherein the adsorption layer is made of one of octadecylsilane bonded silica gel, styrene-divinylbenzene copolymer or benzenesulfonated polystyrene-divinyl polymer.

[0008] The fourth technical solution is based on the third technical solution, wherein the particle size of the octadecylsilane bonded silica gel is 1 to 100 microns.

[0009] The fifth technical solution is based on the third technical solution, wherein the particle size of the styrene-divinylbenzene copolymer is 1 to 150 microns.

[0010] The sixth technical solution is based on the third technical solution, wherein the particle size of the benzenesulfonated polystyrene-divinyl polymer is 1 to 50 microns.

[0011] The seventh technical solution is based on any one of the third to sixth technical solutions, wherein each adsorption layer is coated with filter paper, dust-free paper or non-woven fabric.

[0012] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0013] Since the shell is made of hard material, it can protect the adsorption layer, and the several through holes on it are suitable for water to pass through, so the adsorption layer can contact the water body and absorb the narcotic drugs in the water body. The adsorption layers are nested with each other, and no matter what the flow direction of the water body is, it can flow to each adsorption layer, and it is also convenient to distinguish each adsorption layer when the narcotic drug adsorption device is subsequently recovered for component inspection. In actual use, the narcotic drug adsorption device provided by the present technical solution can be placed in various water bodies, so as to conduct continuous adsorption qualitative monitoring of the components of the water body. Then, the narcotic drug adsorption device is regularly recovered to check the adsorbed substances therein, so as to determine whether there are drug users during this period of time. This method does not infringe on personal privacy, and can continuously monitor within a specific time period without manual supervision.

[0014] For some special scenarios, such as when it is necessary to place the drug into a water pipe, it is necessary to consider the stability of the position of the drug adsorption device and maximize the contact area between the device and the water flow. Therefore, by making the outer surface of the shell include a first semi-cylindrical surface and a second semi-cylindrical surface extending in the same direction and coaxially arranged, on the projection surface perpendicular to the extension direction of the first semi-cylindrical surface and the second semi-cylindrical surface, the starting point and end point of the projection of the first semi-cylindrical surface and the second semi-cylindrical surface are both located in the same straight line, so that the outer shape of the shell is roughly a semi-circular cylinder, which can be installed in a cylindrical water pipe without shaking in the radial direction of the water pipe, and when the water flow in the water pipe is small (only a small amount of water is discharged against the wall), the device can contact and adsorb with the water.

[0025] Embodiment 1

[0026] like Figure 1As shown, this embodiment provides a device for adsorbing narcotic drugs, which is roughly spherical, and includes a shell 1 and at least two adsorption layers. The shell 1 is made of hard material and is provided with a plurality of through holes so as to be suitable for water to pass through. The adsorption layers are used to adsorb narcotic drugs in the water, which are nested and installed in the shell 1. The adsorption layer in this embodiment takes two layers as an example, which includes a first adsorption layer 2 and a second adsorption layer 3, and the second adsorption layer 3 is located in the first adsorption layer 2. The diameter of the second adsorption layer 3 is about 20 mm, and the thickness of the first adsorption layer 2 and the shell 1 are both about 10 mm.

[0027] The hard material used to make the housing 1 is plastic in this embodiment, but other materials, such as a grid-shaped metal shell, may also be used.

[0028] The adsorption layer can be made of one of octadecylsilane bonded silica gel, styrene-divinylbenzene copolymer or benzenesulfonated polystyrene-divinyl polymer as required. Among them, the particle size of octadecylsilane bonded silica gel can be 1 to 100 microns, the particle size of styrene-divinylbenzene copolymer can be 1 to 150 microns, and the particle size of benzenesulfonated polystyrene-divinyl polymer can be 1 to 50 microns. In this embodiment, the first adsorption layer 2 is made of octadecylsilane bonded silica gel, and the second adsorption layer 3 is made of styrene-divinylbenzene copolymer. As required, the materials of the first adsorption layer 2 and the second adsorption layer 3 can also be the same.

[0029] In addition, since the particle size of the material used in the interlayer adsorption layer is relatively small, each adsorption layer is also coated with filter paper, which can play a shaping role while avoiding mutual confusion and scattering. In other embodiments, dust-free paper, non-woven fabrics and other materials can also be used.

[0030] When manufacturing the narcotic drug adsorption device of this embodiment, the material of the second adsorption layer 3 is firstly pressed by physical pressure so that it is wrapped in the filter paper, and then the first adsorption layer 2 is pressed by physical pressure so that it is wrapped outside the filter paper of the second adsorption layer 3, and then the first adsorption layer 2 is wrapped with filter paper. Then the housing 1 is wrapped outside the filter paper of the first adsorption layer 2.

[0031] The testing process of the narcotic drug adsorption device in this embodiment is as follows:

[0032] First, water is allowed to continuously flush the narcotic drug adsorption device at a flow rate of 5 ml / min, and then the water flow flushing is stopped, and the prepared 50 ml standard solution (50 ng / ml morphine, ketamine, methamphetamine) is flushed into the sphere at a flow rate of 60 ml / min. Then the water flow flushing is continued for 3 hours. After the flushing is completed, the material inside the shell 1 is taken out to a beaker, 5 ml of methanol is added, ultrasonic extraction is performed for 10 minutes, and after filtering with a 0.22 micron needle filter, it is analyzed using a liquid chromatography-mass spectrometer.

[0033] Three groups of experiments were conducted, and morphine, ketamine and methamphetamine were detected in all three groups. The morphine content was 18.1ng / mL, 55.6ng / mL, and 23.0ng / mL respectively; the ketamine content was 60.1ng / mL, 50.8ng / mL, and 80.3ng / mL; and the methamphetamine content was 200.2ng / mL, 250.9ng / mL, and 189.7ng / mL respectively, indicating that the device can effectively adsorb the target to be tested.

[0034] In this embodiment, since the shell 1 is made of hard material, it can protect the adsorption layer, and the several through holes thereon are suitable for water to pass through, so the adsorption layer can contact the water body and absorb the narcotic drugs in the water body. The adsorption layers are nested with each other, and no matter what the flow direction of the water body is, it can flow to each adsorption layer, and it is also convenient to distinguish each adsorption layer when the narcotic drug adsorption device is subsequently recovered for component inspection. In actual use, the narcotic drug adsorption device provided by the present technical solution can be placed in various water bodies, so as to conduct continuous adsorption qualitative monitoring of the components of the water body. Then, the narcotic drug adsorption device is regularly recovered to check the adsorbed substances therein, so as to determine whether there are drug addicts during this period of time. This method does not infringe on personal privacy, and can continuously monitor within a specific time period without manual supervision.

[0035] Embodiment 2

[0036] The present embodiment is different from the first embodiment in that the shapes of the shell 1 and the adsorption layer are different.

[0037] like Figure 2 As shown, in this embodiment, the outer surface of the shell 1 includes a first semi-cylindrical surface 4 and a second semi-cylindrical surface 5 extending in the same direction and arranged coaxially. On the projection surface perpendicular to the extending direction of the first semi-cylindrical surface 4 and the second semi-cylindrical surface 5, the starting point and the end point of the projection of the first semi-cylindrical surface 4 and the second semi-cylindrical surface 5 are both located in the same straight line, so that the outer shape of the shell 1 is roughly a semi-cylindrical ring, and the first adsorption layer 2 and the second adsorption layer 3 are also roughly semi-cylindrical rings. Therefore, for some more special scenes, such as the need to put it into a water pipe, the narcotic drug adsorption device can be installed in a cylindrical water pipe without shaking along the radial direction of the water pipe, and the contact area between the device and the water body is increased.

[0038] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
