Abstract
Description
Technical Field
[0001] This utility model relates to the field of drug testing, and in particular to a drug testing solution preparation device. Background Technology
[0002] In drug testing, standard solutions are used for comparative analysis with the drug solution to be tested. For example, in content determination, it is necessary to accurately prepare a series of standard solutions with known concentrations. Taking the determination of drug content by high performance liquid chromatography as an example, by preparing standard solutions of different concentrations, a standard curve is established. In this way, when the chromatographic peak area or peak height of the drug to be tested is compared with the standard curve, the content of the active ingredient in the drug can be accurately calculated.
[0003] A search revealed Chinese Patent Publication No. CN220990637U, which discloses a drug testing and preparation device. This device includes a stepper motor, a rotating shaft, stirring blades, a connecting plate, a base plate, an auxiliary rod, a first cleaning plate, a second cleaning plate, a first scraper, and a second scraper. It facilitates the stirring of drug residues on the inner wall of a mixing tank. The stepper motor drives the rotating shaft, which in turn drives the connecting plate and the base plate via the stirring blades. This, in turn, causes the first and second cleaning plates to rotate, further rotating the first and second scrapers. This process effectively removes residues from the inner wall of the mixing tank, increasing mixing efficiency and promoting uniform mixing of the drug solution.
[0004] In the above technical solution, multiple sets of cleaning plates and scrapers are used to clean the drug residue on the tank wall. However, when preparing a solution with a high viscosity, the cleaning plates and scrapers will only transfer the drug solution to the adhering body after scraping off the residue, making it difficult to completely remove it. When cleaning with scrapers, water is needed, and a large amount of cleaning solvent is also required, which reduces the cleaning efficiency. Therefore, a drug testing solution preparation device is proposed to solve the above problems. Utility Model Content

[0013] As a further description of the above technical solution:
[0014] A second motor is fixedly connected to the top of the top cover. A rotating shaft is fixedly connected to the output end of the second motor. A drive wheel is fixedly connected to the outer wall of the rotating shaft. A gear ring is fixedly connected to the inner surface of the water collection ring.

At the same time, when cleaning is required, the opening of the mixing tank is sealed to prevent water from splashing out and causing the medicine to pollute the environment.
[0023] 2. In this utility model, by combining the structure of motor 2, rotating shaft, drive wheel, gear ring, annular groove and slider, the high-pressure nozzle is driven to rotate and switch the rinsing position during high-pressure rinsing, thereby expanding the rinsing area and improving the cleaning efficiency.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a drug testing solution preparation device, including an operating table 1. A solution preparation tank 2 is fixedly connected to the surface of the operating table 1. A liquid outlet pipe is provided on the surface of the solution preparation tank 2, and a valve is provided on the liquid outlet pipe for discharging the drug solution after preparation. A motor 3 is fixedly connected to the bottom of the operating table 1. A rotating rod 4 is fixedly connected to the output end of the motor 3. The rotating rod 4 passes through the operating table 1 and enters the interior of the solution preparation tank 2. A stirring blade 5 is fixedly connected to the outer wall of the rotating rod 4. Several sets of stirring blades 5 are provided, and the several sets of stirring blades 5 are evenly distributed on both sides of the outer wall of the rotating rod 4. The stirring blades 5 are located in the bottom area of the solution preparation tank 2 to avoid sedimentation and are close to the liquid outlet pipe to prevent blockage. A cylinder 7 is fixedly connected to the surface of the operating table 1. A top cover 6 is fixedly connected to the output end of the cylinder 7. A limit rod 8 is fixedly connected to the top of the top cover 6. The limit rod 8 passes through the operating table 1, and the outer wall of the limit rod 8 is slidably connected to the inner wall of the operating table 1.
[0033] Reference Figures 3-5 The top cover 6 has a water collection ring 13 inside, which is hollow. A high-pressure nozzle 14 is fixedly connected to the surface of the water collection ring 13. Several groups of high-pressure nozzles 14 are arranged at equal intervals. Each group of high-pressure nozzles 14 is equipped with a valve to control the water output of the high-pressure nozzles 14. The high-pressure nozzles 14 are inclined, which makes it easier to spray water onto the tank wall of the liquid preparation tank 2 that the nozzles of the high-pressure nozzles 14 face. A water supply pipe 17 is fixedly connected to the inner wall of the water collection ring 13. A portion of the water supply pipe 17 is retractable. The water supply pipe 17 passes through the top cover 6. A high-pressure water pump 18 is fixedly connected to the end of the water supply pipe 17. The bottom of the high-pressure water pump 18 is fixedly connected to the top of the operating platform 1.
[0034] Reference Figures 4-5 A motor 9 is fixedly connected to the top of the top cover 6. A rotating shaft 10 is fixedly connected to the output end of the motor 9. The outer wall of the rotating shaft 10 is rotatably connected to the inner wall of the top cover 6. A drive wheel 11 is fixedly connected to the outer wall of the rotating shaft 10. A gear ring 12 is fixedly connected to the inner surface of the water collecting ring 13. The drive wheel 11 meshes with the gear ring 12. An annular groove 15 is opened on the inner surface of the top cover 6. A slider 16 is slidably connected to the inner wall of the annular groove 15. The outer wall of the slider 16 is fixedly connected to the outer wall of the water collecting ring 13. Three sets of sliders 16 are provided, and the three sets of sliders 16 are equidistantly distributed on the outer wall of the water collecting ring 13 to provide displacement guidance when the water collecting ring 13 rotates.
[0035] Working principle: The required proportions of raw materials are added into the mixing tank 2. Motor 3 drives the rotating rod 4 to rotate, causing the stirring blade 5 to stir and mix the raw materials. After the liquid is mixed, it is discharged through the outlet pipe. The high-pressure water pump 18 is connected to tap water through a pipeline. The cylinder 7 drives the top cover 6 to descend and cover the mixing tank 2. The high-pressure water pump 18 injects water into the water collecting ring 13. Using the central axis of the water collecting ring 13 as a dividing line, a set of high-pressure nozzles 14 on the left side of the water collecting ring 13 opens and sprays water to flush the mixing tank 2. The motor 29 reciprocates, driving the shaft 10 to rotate in both directions. This causes the drive wheel 11 to drive the gear ring 12, which meshes with it, to rotate. Consequently, the water collection ring 13 reciprocates within the top cover 6, expanding the spray area of the high-pressure nozzles 14. After a period of circulation, the high-pressure nozzles 14 on the left are turned off, and the high-pressure nozzles 14 on the right are turned on. The above steps are repeated to thoroughly rinse the mixing tank 2. High-pressure rinsing of the mixing tank 2 prevents viscous, highly active, or trace amounts of medicine from remaining on the tank wall, which could affect the accuracy of subsequent mixing ratios.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
