Description

Technical Field

[0001] This invention relates to the field of drug assay technology, specifically to a portable drug assay device and method based on ion exchange method. Background Technology

[0002] Ion exchange is the process or phenomenon in which ions in a solution exchange with ions on a certain ion exchanger. It is carried out by exchanging ions in a solid ion exchanger with ions in a dilute solution to extract or remove certain ions from the solution. It is a unit operation belonging to the mass transfer separation process. Ion exchange is a reversible equivalence exchange reaction.

[0003] In the existing technology, although the existing drug testing devices have solved the problem of drug testing, the size of the drug testing devices is relatively large and inconvenient to carry, making it impossible to carry the testing device with you to test drugs. In order to solve the above problems, we propose a portable drug testing device and testing method based on ion exchange method. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a portable drug assay device based on ion exchange method, comprising a shell, a rotating plate rotatably connected to the top of the shell, a placement component fixedly connected to the bottom of the inner cavity of the shell, a clamping component fixedly connected to the top edge of the placement component, a shaking component fixedly connected to the center of the top of the placement component, a block fixedly connected to the top of the placement component, a cotton swab box fixedly connected to the top of the block, a test strip box fixedly connected to the side of the top of the block away from the cotton swab box, and a handle fixedly connected to the top of the rotating plate. The clamping component places and fixes the test tubes, preventing them from shaking during movement. The placement component reduces internal vibration during use, protecting the test tubes and preventing damage caused by external forces during vibration. The shaking component mixes the solution and drug, allowing for the mixing of multiple test tubes at once, improving mixing efficiency and effectiveness.

[0005] Preferably, the clamping assembly includes an outer frame, the bottom of which is fixedly connected to the top of the placement assembly, and an insulation layer is fixedly connected to the inner surface of the outer frame. A circular groove is provided on the top of the insulation layer, and the test tube is fixed by the clamping assembly.

[0006] Preferably, a sponge block is fixedly connected to the bottom of the inner cavity of the circular groove, and an elastic plate is fixedly connected to the inner surface of the circular groove. By setting a clamping assembly, the test tube is fixed. Since the elastic plate is elastic, it can clamp test tubes of different sizes, prevent the test tubes from moving around inside the device, and reduce the probability of test tube damage.

[0007] Preferably, the placement component includes a sliding plate, the outer surface of which is slidably connected to the inner surface of the outer shell. A shock-absorbing component is fixedly connected to the bottom of the sliding plate, and an elastic pad is fixedly connected to the bottom of the shock-absorbing component. The bottom of the elastic pad is fixedly connected to the bottom of the inner cavity of the outer shell. By setting the placement component, the test tube can be shock-absorbing during movement, reducing the impact force inside the device and preventing external forces from damaging the test tube when vibration occurs.

[0008] Preferably, the shock absorption assembly includes a top plate, the top of which is fixedly connected to the bottom of the slide plate, a shock absorption spring is fixedly connected to the bottom of the top plate, a bottom plate is fixedly connected to the bottom end of the shock absorption spring, and the bottom of the bottom plate is fixedly connected to the top of the elastic pad. The shock absorption assembly and the elastic pad absorb the vibration generated when the device moves, thus protecting the inside of the device.

[0009] Preferably, the shaking assembly includes a connecting plate, the bottom of which is fixedly connected to the top of the placement assembly. A motor is fixedly installed on the outer surface of the connecting plate, and the output end of the motor passes through the connecting plate and is fixedly connected to a rotating frame. By setting the shaking assembly, the test tubes are shaken to mix the medicine and solution. Multiple test tubes can be mixed at once, which improves the shaking efficiency and effect and speeds up the determination of drug samples.

[0010] Preferably, a support plate is fixedly connected to the bottom of the inner cavity of the rotating frame, a fixing plate is fixedly connected to the top of the inner surface of the rotating frame, and a movable plate is slidably connected to the top of the inner surface of the rotating frame. The test tube is fixed by the movable plate and the fixing plate to prevent the test tube from shaking during the shaking process, which would affect the shaking of the medicine.

[0011] Preferably, the movable plate includes a sliding plate, the outer surface of which is slidably connected to the top of the inner surface of the rotating frame. A threaded rod is rotatably connected to the side of the sliding plate away from the fixed plate. A straight plate is threadedly connected to the outer surface of the threaded rod. The outer surface of the straight plate is fixedly connected to the inner surface of the rotating frame. The position of the movable plate is adjusted by the threaded rod so that the shaking assembly can fix test tubes of different sizes.

[0012] Preferably, a rebound spring is fixedly connected to the side of the sliding plate and the fixed plate that are close to each other, and an arc-shaped plate is fixedly connected to the other end of the rebound spring. The test tube is fixed by the arc-shaped plate, and the rebound spring makes the arc-shaped plate hold the test tube relatively gently without damaging the test tube.

[0013] A method for determining drugs using a portable drug assay device based on ion exchange includes the following steps:

[0014] Step 1: Sampling. Take out a cotton swab from the cotton swab box, insert the cotton swab into the drug to be tested, and take out a small amount of drug sample. Take out the test tube from the clamping assembly, place the cotton swab into the test tube, so that the obtained sample comes into contact with the solution in the test tube. The drug is measured by detecting whether ion exchange occurs between the obtained sample and the solution in the test tube.

[0015] Step 2: Shake well. Place the test tube between the fixed plate and the movable plate, with the bottom of the test tube extending into the support plate. The movable plate and the fixed plate hold the test tube in place. The motor drives the rotating frame to swing back and forth, which in turn drives the movable plate and the fixed plate to swing back and forth. The movable plate and the fixed plate then drive the test tube to swing back and forth. The shaking assembly shakes the sample and solution well, allowing them to react.

[0016] Step 3: Measurement. Take out the pH test strip from the test strip box, remove the test tube from the clamping assembly, take out a small amount of solution from the test tube, drop the solution to be tested onto the pH test strip, wait for a period of time, observe the color change of the test strip, and determine whether ion exchange has occurred by measuring the pH value of the solution.

[0017] Step 4: Colorimetric analysis. Take out the comparison card and place the pH test strip next to the comparison card. Compare the pH test strip and the comparison card, and observe the color of the pH value of the solution itself on the comparison card and the color shown on the pH test strip. If the two colors are the same, the substance to be measured is not present in the medicine. If the two colors are different, the substance to be measured is present in the medicine.

[0018] This invention provides a portable drug assay device and method based on ion exchange. It offers the following advantages:

[0019] I. The portable drug assay device and method based on ion exchange method are used to determine drugs. The device is small in size and easy to carry, which solves the problem that the existing assay devices are large in size and inconvenient for users to carry.

[0020] II. The portable drug assay device and method based on ion exchange method, by setting up a placement component, can dampen the test tube during movement, reduce the impact force on the inside of the device, and prevent external forces from damaging the test tube when vibration occurs.

[0021] III. The portable drug assay device and method based on ion exchange method uses a clamping assembly to fix the test tubes. Due to the elasticity of the elastic plate, it can clamp test tubes of different sizes, preventing the test tubes from moving around inside the device and reducing the probability of test tube damage.

[0022] IV. The portable drug assay device and method based on ion exchange method, by setting up a shaking component, drives the test tube to shake, so as to shake the drug and solution evenly. Multiple test tubes can be shaken at one time, which improves the shaking efficiency and effect and speeds up the determination of drug samples. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0033] Example 1

[0034] like Figures 1-5 As shown, the present invention provides a technical solution: a portable drug assay device and method based on ion exchange method, comprising a shell 1, a rotating plate 8 rotatably connected to the top of the shell 1, a placement component 2 fixedly connected to the bottom of the inner cavity of the shell 1, a clamping component 3 fixedly connected to the top edge of the placement component 2, a shaking component 4 fixedly connected to the center of the top of the placement component 2, a block 5 fixedly connected to the top of the placement component 2, a cotton swab box 6 fixedly connected to the top of the block 5, a test strip box 7 fixedly connected to the side of the top of the block 5 away from the cotton swab box 6, and a handle 9 fixedly connected to the top of the rotating plate 8. In use, the placement component 2 contains test tubes, and the test strips are placed inside the test tubes... For drug sampling, the sample is placed inside a test tube, which is then placed inside the shaking assembly 4. The shaking assembly 4 shakes the sample evenly. The solution after shaking is then measured, and the change in pH value is observed to determine whether an ion exchange reaction has occurred. The drug is then measured. When moving the device, it is moved using the handle 9. The test tube is placed and fixed by the clamping assembly 3 to prevent it from shaking during movement. The placement assembly 2 reduces internal vibration during use, protecting the test tube and preventing damage caused by external forces during vibration. The shaking assembly 4 shakes the solution and drug evenly, and can shake multiple test tubes at once, improving the shaking efficiency and effect.

[0035] The clamping component 3 includes an outer frame 31, the bottom of which is fixedly connected to the top of the placement component 2. An insulation layer 32 is fixedly connected to the inner surface of the outer frame 31. A circular groove 33 is provided on the top of the insulation layer 32. A pre-prepared test tube is placed inside the circular groove 33 and the test tube is fixed by the clamping component 3.

[0036] A sponge block 34 is fixedly connected to the bottom of the inner cavity of the circular groove 33, and an elastic plate 35 is fixedly connected to the inner surface of the circular groove 33. The test tube is placed inside the circular groove 33, with the bottom of the test tube contacting the sponge block 34. The elastic plate 35 presses against the outer surface of the test tube. The test tube is fixed by the clamping assembly 3. Because the elastic plate 35 is elastic, it can clamp test tubes of different sizes, preventing the test tubes from moving around inside the device and reducing the probability of test tube damage.

[0037] The placement component 2 includes a slide plate 21, the outer surface of which is slidably connected to the inner surface of the outer shell 1. A shock-absorbing component 22 is fixedly connected to the bottom of the slide plate 21, and an elastic pad 23 is fixedly connected to the bottom of the shock-absorbing component 22. The bottom of the elastic pad 23 is fixedly connected to the bottom of the inner cavity of the outer shell 1. During the movement of the device, the device is vibrated, causing the slide plate 21 to vibrate. The slide plate 21 causes the shock-absorbing component 22 and the elastic pad 23 to deform. The shock-absorbing component 22 and the elastic pad 23 provide a buffer for the slide plate 21. By setting the placement component 2, the test tube can be shock-absorbing during the movement, reducing the impact force inside the device and preventing external forces from damaging the test tube when vibration occurs.

[0038] The shock absorption assembly 22 includes a top plate 221, the top of which is fixedly connected to the bottom of the slide plate 21. A shock absorption spring 222 is fixedly connected to the bottom of the top plate 221, and a bottom plate 223 is fixedly connected to the bottom of the shock absorption spring 222. The bottom of the bottom plate 223 is fixedly connected to the top of the elastic pad 23. During the movement of the device, the slide plate 21 causes the top plate 221 to vibrate, the top plate 221 causes the shock absorption spring 222 to deform, and the shock absorption spring 222 causes the bottom plate 223 and the elastic pad 23 to vibrate. The shock absorption assembly 22 and the elastic pad 23 absorb the vibration generated when the device moves, thus protecting the inside of the device.

[0039] In use, by placing component 2 as a protective device, during the movement of the device, the device is vibrated, causing the sliding plate 21 to vibrate. The sliding plate 21 causes the top plate 221 to vibrate, and the top plate 221 causes the shock-absorbing spring 222 to deform. The shock-absorbing spring 222 causes the bottom plate 223 and the elastic pad 23 to vibrate. The shock-absorbing spring 222 and the elastic pad 23 reduce the vibration of the device. At the same time, the pre-prepared test tubes are placed inside the circular groove 33, with the bottom of the test tubes contacting the sponge block 34. The elastic plate 35 presses down on the outer surface of the test tubes. The clamping component 3 can fix test tubes of different specifications.

[0040] Example 2

[0041] like Figures 1-8 As shown, the shaking assembly 4 includes a connecting plate 41. The bottom of the connecting plate 41 is fixedly connected to the top of the placement assembly 2. A motor 42 is fixedly installed on the outer surface of the connecting plate 41. The output end of the motor 42 passes through the connecting plate 41 and is fixedly connected to a rotating frame 43. In use, the test tube is placed inside the rotating frame 43, and the motor 42 drives the rotating frame 43 to swing back and forth. The rotating frame 43 drives the test tube to swing back and forth. By setting the shaking assembly 4, the test tube is shaken to shake the medicine and solution. Multiple test tubes can be shaken at one time, which improves the shaking efficiency and effect and speeds up the determination of drug samples.

[0042] A support plate 44 is fixedly connected to the bottom of the inner cavity of the rotating frame 43, a fixed plate 45 is fixedly connected to the top of the inner surface of the rotating frame 43, and a movable plate 46 is slidably connected to the top of the inner surface of the rotating frame 43. When in use, the test tube is placed between the fixed plate 45 and the movable plate 46. The fixed plate 45 and the movable plate 46 hold the test tube in place and fix the test tube by the movable plate 46 and the fixed plate 45 to prevent the test tube from shaking during the shaking process, which would affect the shaking of the medicine.

[0043] The movable plate 46 includes a sliding plate 461. The outer surface of the sliding plate 461 is slidably connected to the top of the inner surface of the rotating frame 43. A threaded rod 462 is rotatably connected to the side of the sliding plate 461 away from the fixed plate 45. A straight plate 463 is threadedly connected to the outer surface of the threaded rod 462. The outer surface of the straight plate 463 is fixedly connected to the inner surface of the rotating frame 43. In use, the threaded rod 462 is adjusted, which drives the straight plate 463 to move. The distance between the straight plate 463 and the fixed plate 45 is adjusted. The position of the movable plate 46 is adjusted by the threaded rod 462, so that the shaking component 4 can fix test tubes of different specifications.

[0044] Both the sliding plate 461 and the fixed plate 45 are fixedly connected to a spring 464 on their adjacent sides. The other end of the spring 464 is fixedly connected to an arc plate 465. In use, the straight plate 463 drives the spring 464 and the arc plate 465 to move. The surface of the arc plate 465 contacts the test tube and presses down on the surface of the test tube. The test tube is fixed by the arc plate 465. The spring 464 makes the arc plate 465 hold the test tube relatively gently and will not damage the test tube.

[0045] In use, a small amount of drug sample is extracted using a cotton swab. The test tube is then removed from the clamping assembly 3, and the cotton swab is placed inside the test tube so that the sample comes into contact with the solution in the test tube. The test tube is then placed between the fixed plate 45 and the movable plate 46. The threaded rod 462 is adjusted, which moves the straight plate 463. The straight plate 463 moves the return spring 464 and the arc plate 465. The surface of the arc plate 465 contacts the test tube, pressing down on the surface of the test tube and fixing it in place. After the test tube is fixed, the motor 42 drives the rotating frame 43 to swing back and forth. The rotating frame 43 drives the fixed plate 45 and the movable plate 46 to swing back and forth, which in turn causes the test tube to swing back and forth, shaking the drug and solution evenly.

[0046] Example 3

[0047] like Figures 1-8 As shown, a method for determining drugs using a portable drug assay device based on ion exchange includes the following steps:

[0048] Step 1: Sampling. Take out a cotton swab from the cotton swab box 6, insert the cotton swab into the drug to be tested, and take out a small amount of drug sample. Take out the test tube from the clamping assembly 3, place the cotton swab into the test tube, so that the obtained sample comes into contact with the solution in the test tube. The drug is measured by detecting whether ion exchange occurs between the obtained sample and the solution in the test tube.

[0049] Step 2: Shake well. Place the test tube between the fixed plate 45 and the movable plate 46, with the bottom of the test tube extending into the support plate 44. The movable plate 46 and the fixed plate 45 hold the test tube in place. The motor 42 drives the rotating frame 43 to swing back and forth. The rotating frame 43 drives the movable plate 46 and the fixed plate 45 to swing back and forth. The movable plate 46 and the fixed plate 45 drive the test tube to swing back and forth. The shaking component 4 shakes the sample and solution well, allowing the sample and solution to react.

[0050] Step 3: Measurement. Take out the pH test paper from the test paper box 7, remove the test tube from the clamping assembly 3, take out a small amount of solution from the test tube, drop the solution to be tested onto the pH test paper, wait for a period of time, observe the color change of the test paper, and determine whether ion exchange has occurred by measuring the pH value of the solution.

[0051] Step 4: Colorimetric analysis. Take out the comparison card and place the pH test strip next to the comparison card. Compare the pH test strip and the comparison card, and observe the color of the pH value of the solution itself on the comparison card and the color shown on the pH test strip. If the two colors are the same, the substance to be measured is not present in the medicine. If the two colors are different, the substance to be measured is present in the medicine.

[0052] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
