Description

Technical Field

[0001] This invention relates to the field of drug titration technology, and in particular to a quantitative drug analysis titration device. Background Technology

[0002] Titration analysis is an analytical method in which a standard solution of known and accurate concentration is added dropwise to a solution of the analyte until the amount of the added solution reacts completely according to stoichiometry. Then, based on the concentration of the added standard solution and the volume consumed, the content of the analyte is calculated using a smart sensor.

[0003] There are many existing technologies for titration devices, such as: Chinese invention patent CN214427376U discloses a drug analysis titration device, relating to the field of drug analysis technology. This invention includes an analysis device, a fixing device, and a titration device. The fixing device is mounted on the upper surface of the analysis device, and the titration device is welded to one surface of the analysis device. A base plate is welded to one side of the housing, and a pressure sensor is connected to the upper surface of the base plate. A battery and an information processing chip are installed on the bottom surface inside the housing. A button and a display screen are mounted on one surface of the housing, and a bracket is welded to the upper surface of the housing. An analysis bottle and several locking plates are mounted on the upper surface of a load-bearing plate. Springs are mounted on the opposing surfaces of two locking plates, and a fixing clip is welded to the other end of each spring. A bolt is installed through one surface of the fixing clip, and a nut is mounted on the other surface. A fixing ring is connected to the other end of a connecting rod, and a limit post is connected through the circumference of the fixing ring. This invention, by setting up the analysis device, fixing device, and titration device, achieves rapid and accurate drug analysis while preventing shaking.

[0004] However, some problems still exist in actual use: 1. In traditional titration apparatus, after the reagent solution is added to the analysis cup, the mixture needs to be continuously stirred manually by the operator in order to monitor the chemical reaction process in real time, ensure the reaction is complete and the data is accurate. This operation not only requires a high level of skill and consistency from the operator, but also significantly increases the intensity of manual labor.

[0005] 2. For titration analysis of batch drug samples, traditional devices require operators to manually perform operations such as clamping, positioning, and picking up and putting down the injection containers one by one. Frequent repetitive actions reduce the analysis efficiency of a single sample and prolong the overall time of batch testing, resulting in low testing and analysis efficiency. Summary of the Invention

[0006] In order to overcome the above-mentioned defects in the prior art, the present invention provides a quantitative drug analysis titration device.

[0007] To achieve the above objectives, the present invention provides a quantitative drug analysis titration device, comprising an analysis platform, a support frame above the analysis platform, a placement box on the surface of the analysis platform for holding an analysis cup, a sensor at the bottom of the placement box, an injection container above the placement box, a graduated scale on the surface of the injection container for collecting drug solution, clamping components on both sides of the injection container for limiting the injection container to be perpendicular to the horizontal plane, a quantitative component above the injection container for squeezing the injection container to quantitatively drip the drug solution inside into the analysis cup, a hollow groove inside the analysis platform, and a stirring component inside the hollow groove for stirring the drug mixture, while simultaneously centrifugally rotating the drug adhering to its surface during stirring, causing the drug solution to detach from the surface of the stirring component.

[0008] Furthermore, the injection head at the bottom of the injection container is provided with a sealing membrane, and a cross-shaped cutter is provided on the surface of the sealing membrane.

[0009] Furthermore, the clamping assembly includes a column cylinder with two sides of the upright frame, a slide rod slidably mounted on the inner wall of the column cylinder, a clamping plate at the end of the slide rod, and a compression spring between the column cylinder and the slide rod.

[0010] Furthermore, the end of the slide bar is provided with a magnetic rod, which extends through the column to the outside of the stand, and the injection container is clamped by pushing the magnetic rod to move relative to each other.

[0011] Furthermore, the outer wall of the support frame is provided with a mounting frame, the inside of the mounting frame is provided with an iron core, and the surface of the iron core is provided with a wire. By controlling the direction of the current in the wire, the magnetic poles generated on the surface of the iron core are changed.

[0012] Furthermore, the quantitative component includes a rotating motor with a top of a stand, a lead screw at the output end of the rotating motor, a pressure plate on the surface of the lead screw, the pressure plate being located above the injection container, and the rotation of the lead screw causing the pressure plate to move in the vertical direction.

[0013] Furthermore, the agitation assembly includes a servo motor disposed inside the hollow groove. The output end of the servo motor is provided with a main gear, and there are auxiliary gear rods on both sides of the main gear. A movable seat is provided on the surface of the auxiliary gear rod. When the auxiliary gear rod rotates, it drives the movable seat to move relative to it.

[0014] Furthermore, the top of the movable seat is provided with a hollow column, the surface of the hollow column is provided with an arc-shaped groove, a movable rod is slidably provided on the inner wall of the hollow column, an elastic element is provided between the hollow column and the movable rod, a stirring blade is provided at the end of the movable rod, a pedal is provided between the movable rod and the stirring blade, a protrusion is provided at the top of the movable rod, and the protrusion slides on the surface of the arc-shaped groove when the movable rod slides along the inner wall of the hollow column.

[0015] Furthermore, cylinders are provided on both sides of the hollow column, and a base plate is provided on the piston rod at the end of the cylinder. When the base plate moves downward in the vertical direction, it squeezes the pedal.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this quantitative drug titration device, the current is energized through the conductor on the surface of the iron core, generating magnetism on the surface of the iron core. At this time, the magnetic poles between the iron core and the magnetic rod are opposite, and the magnetic rod is attracted by the magnetic force of the iron core. During the attraction process, the magnetic rod drives the slide rod to move directly in the opposite direction. At this time, the space between the clamps at the end of the slide rod increases, which facilitates the placement of the injection container. When the injection container is placed between the clamps, the power is cut off to the conductor. At this time, the slide rod is reset by the force of the compression spring, and the clamps at the end of the slide rod limit the outer wall of the clamping assembly to improve the stability of the injection container.

[0017] 2. In this quantitative drug analysis titration device, the output of the control motor drives the lead screw to rotate. During the rotation of the lead screw, the pressure plate moves downward in the vertical direction. During the movement of the pressure plate, the piston shaft is pushed, thereby realizing quantitative titration. When the drug solution reacts with the analytical solution between the analytical cup, the mass of the drug solution is obtained with the help of the sensor, thereby improving the accuracy of the titration analysis.

[0018] 3. In this quantitative drug analysis titration device, the piston rod at the end of the cylinder drives the base plate to move downwards vertically. The base plate pushes the pedal to move downwards repeatedly. During the downward movement of the moving rod, the protrusion slides on the inner wall of the arc-shaped groove, causing the moving rod to rotate during the downward movement. The moving rod drives the stirring blade to move vertically along the inside of the analysis cup. When the stirring blade moves downwards and rotates, it agitates the drug solution dripped into the analysis cup in real time, thereby obtaining the titration result of the drug solution in real time. When the drug solution titration is finished, the moving rod is stopped. At this time, the moving rod is reset by the force of the elastic element, causing the stirring blade to rotate automatically during the upward movement. The drug solution attached to the surface of the stirring blade is detached from the surface of the stirring blade by centrifugal force, improving the accuracy of quantitative drug analysis.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Based on a quantitative drug analysis titration device, according to Figure 1-8As shown, the system includes an analysis table 100, a stand 101 on top of the analysis table 100, a placement box 102 on the surface of the analysis table 100 for holding analysis cups, a sensor 103 at the bottom of the placement box 102, an injection container 200 on top of the placement box 102, graduation lines 201 on the surface of the injection container 200 for collecting medication, and clamping assemblies 300 on both sides of the injection container 200 for holding the injection container 200. The device is positioned to be perpendicular to the horizontal plane. A metering component 400 is provided above the injection container 200. The metering component 400 is used to squeeze the injection container 200 so that the liquid medicine inside is metered and dripped into the analysis cup. A hollow groove 104 is provided inside the analysis stage 100. A stirring component 500 is provided inside the hollow groove 104. The stirring component 500 is used to stir the drug mixture. At the same time, the stirring component 500 centrifuges and rotates the drug attached to its surface during stirring, so that the drug liquid is removed from the surface of the stirring component 500.

[0024] In the drug analysis process, the drug solution needs to be collected in an injection container 200 for subsequent titration analysis. To prevent the drug solution from dripping from the injection end of the injection container 200 due to gravity, thus avoiding waste, the injection container 200 consists of an injection head, an empty container, and a piston rod. The injection head end of the injection container 200 is equipped with a sealing membrane 202. The surface of the sealing membrane 202 has a cross-shaped cutter. When drawing the drug solution, the injection head is placed in the drug solution, and the piston rod is pulled to slide against the inner wall of the empty container. The inside of the empty container is under negative pressure, thereby drawing the drug solution into the empty container through the injection head. During the drawing process, the sealing membrane 202 deforms under the suction force, and the drug solution enters the empty container through the cross-shaped cutter. When the drug solution is drawn out, the suction force on the sealing membrane 202 disappears and returns to its original position, sealing the injection head end and preventing the drug solution from dripping through the injection head, thereby improving the utilization rate of the drug solution.

[0025] When performing quantitative titration on the injection container 200, the drug solution inside the injection container 200 needs to be dripped into the analysis cup. To improve the stability of the injection titration, the injection container 200 needs to be limited and fixed. Therefore, the clamping assembly 300 includes a column 301 with two sides of the support frame 101. A slide rod 302 is slidably provided on the inner wall of the column 301. A clamping plate 303 is provided at the end of the slide rod 302. A compression spring 304 is provided between the column 301 and the slide rod 302. By pushing the clamping plate 303 to move to both sides, the movement of the clamping plate 303 drives the slide rod 302 to move. The rod 302 slides on the inner wall of the cylinder 301. During the sliding process, the rod 302 compresses the compression spring 304, thereby increasing the direct space between the clamping plates 303. The injection container 200 is placed between the clamping plates 303, and the compression of the clamping plates 303 is stopped. The clamping plates 303 are driven by the force of the compression spring 304 to move the rod 302 in a relative direction until the clamping plates 303 clamp and fix the outer wall of the injection container 200. When the drug solution is quantitatively titrated, the piston rod is pushed to slide inside the empty barrel, thereby causing the drug solution in the empty barrel to be quantitatively dripped into the analysis cup.

[0026] Considering that frequent clamping and unclamping of the injection container 200 is required during batch drug analysis, resulting in high labor intensity for operators, a magnetic rod 305 is provided at the end of the slide bar 302. The magnetic rod 305 penetrates the column cylinder 301 to the outside of the stand 101. By pushing the magnetic rod 305 to move relative to the outside of the stand 101, the injection container 200 is clamped on both sides. A mounting frame 306 is provided on the outer wall of the stand 101, and an iron core 307 is provided inside the mounting frame 306. A wire 308 is provided on the surface of the iron core 307. By controlling the direction of the current in the wire 308, the magnetic poles generated on the surface of the iron core 307 change. When it is necessary to clamp the injection container 200, by controlling the current in the wire 308 on the surface of the iron core 307, the iron core 307 becomes magnetic. At this time, the magnetic poles between the iron core 307 and the magnetic rod 305 are opposite, and the magnetic rod 305 is subjected to the iron. The core 307 is attracted by magnetic force, and during the attraction process, the magnetic rod 305 drives the slide rod 302 to move directly in a disjoint direction. At this time, the space directly increased by the clamping plate 303 at the end of the slide rod 302, which facilitates the placement of the injection container 200. When the injection container 200 is placed between the clamping plates 303, the power is cut off by the wire 308. At this time, the slide rod 302 is reset by the force of the compression spring 304, so that the clamping plate 303 at the end of the slide rod 302 limits the outer wall of the clamping assembly 300. In order to improve the stability of the injection container 200, the current direction of the wire 308 is adjusted so that the magnetic pole of the iron core 307 near the magnetic rod 305 is the same as that of the magnetic rod 305. This causes the end of the magnetic rod 305 to be pushed by magnetic force, so that the clamping plate 303 fixes the injection container 200, thereby improving the stability of the injection container 200 and reducing the labor intensity of the operators.

[0027] When the piston rod is pushed by the operator, the lack of precision in the operator's hand movements can easily lead to instability in the titration process of the drug solution in the empty container, affecting the analysis results. Therefore, the quantitative component 400 includes a rotating motor 401 with a support frame 101 on top. The output end of the rotating motor 401 is equipped with a lead screw 402, and the surface of the lead screw 402 is equipped with a pressure plate 403. The pressure plate 403 is located above the injection container 200. The rotation of the lead screw 402 drives the pressure plate 403 to move vertically. When the injection container 200 is clamped between the clamping plates 303, the output end of the rotating motor 401 is controlled to drive the lead screw 402 to rotate. During the rotation of the lead screw 402, the pressure plate 403 moves downward vertically. During the movement of the pressure plate 403, it pushes the piston rod, thereby realizing quantitative titration. When the drug solution reacts with the analytical solution between the analytical cup, the mass of the drug solution is obtained in conjunction with the sensor 103, improving the accuracy of the titration analysis.

[0028] In drug titration analysis, when the drug solution is dropped into the analysis cup, it needs to be stirred to obtain real-time reaction results. Therefore, the stirring component 500 includes a servo motor 501 disposed inside a hollow groove 104. The output end of the servo motor 501 is provided with a main gear 502, and the main gear 502 is provided with auxiliary gear rods 503 on both sides. A movable seat 504 is provided on the surface of the auxiliary gear rods 503. When the auxiliary gear rods 503 rotate, they drive the movable seat 504 to move relative to each other. A hollow column 505 is provided on the top of the movable seat 504. The hollow column 505 has an arc-shaped groove 509 on its surface. A movable rod 506 is slidably mounted on the inner wall of the hollow column 505. An elastic element 511 is provided between the hollow column 505 and the movable rod 506. A stirring blade 507 is provided at the end of the movable rod 506. A pedal 508 is provided between the movable rod 506 and the stirring blade 507. A protrusion 510 is provided at the top of the movable rod 506. When the movable rod 506 slides along the inner wall of the hollow column 505, the protrusion 510 slides on the surface of the arc-shaped groove 509. The output shaft of the servo motor 501 is controlled to drive the main gear 502 to rotate. When the main gear 502 rotates, it drives the secondary gear rod 503 to mesh and rotate. When the secondary gear rod 503 rotates, the movable seats 504 on both sides of its surface move relative to each other until the movable seats 504 move above the analysis cup. This pushes the movable rod 506 to slide on the inner wall of the hollow column 505. During the movement of the hollow column 505, it drives the stirring blade 507 to move downward in the vertical direction. The end of the movable rod 506 is provided with a protrusion 510. Therefore, during the downward movement of the movable rod 506, it drives the protrusion 510 to slide on the inner wall of the arc-shaped groove 509, thereby causing the movable rod 506 to rotate during the downward movement. The moving rod 506 drives the stirring blade 507 to move vertically along the inside of the analysis cup. When the stirring blade 507 moves down and rotates, it stirs the drug solution dripped into the analysis cup in real time, thereby obtaining the titration result of the drug solution in real time. When the drug solution titration is finished, the moving rod 506 is stopped. At this time, the moving rod 506 is reset by the force of the elastic element 511, causing the stirring blade 507 to rotate automatically during the upward movement. The drug solution attached to the surface of the stirring blade 507 is detached from the surface of the stirring blade 507 by the centrifugal force, thereby improving the accuracy of drug quantitative analysis.

[0029] When the drug solution is dripped into the analytical cup for analysis, in order to improve the mixing effect between the drug solution and the analytical solution, cylinders 512 are provided on both sides of the hollow column 505. The piston rod at the end of the cylinder 512 is provided with a base plate 513. When the base plate 513 moves downward in the vertical direction, it squeezes the pedal 508. By controlling the piston rod at the end of the cylinder 512, the base plate 513 is driven to move downward in the vertical direction. The base plate 513 pushes the pedal 508 to move downward repeatedly, so that the stirring blade 507 at the end of the moving rod 506 rotates continuously, thereby realizing the rapid mixing of the drug solution and the analytical solution. At the same time, after the titration analysis is completed, the displacement of the piston rod at the end of the cylinder 512 can be controlled to make the stirring blade 507 detach from the mixture and continue to rotate repeatedly. The drug solution adhering to the surface of the stirring blade 507 is separated by centrifugal force.

[0030] In practical use, by pulling the piston rod to slide against the inner wall of the empty barrel, the inside of the empty barrel is in a negative pressure state, thereby drawing the medicine into the empty barrel through the injection head. During the suction process, the sealing membrane 202 is deformed by the suction force, and the medicine enters the empty barrel through the cross-shaped cutter. When the medicine is completely drawn out, the suction force on the sealing membrane 202 disappears and returns to its original position, sealing the end of the injection head and preventing the medicine from dripping through the injection head, thereby improving the utilization rate of the medicine. When it is necessary to clamp the injection container 200, the current is controlled to flow through the wire 308 on the surface of the iron core 307, generating magnetism on the surface of the iron core 307. At this time, the magnetic poles of the iron core 307 and the magnetic rod 305 are opposite. The magnetic rod 305 is attracted by the magnetic force of the iron core 307. During the attraction process, the magnetic rod 305 drives the slide rod 302 to move directly in the opposite direction. At this time, the space of the clamping plate 303 at the end of the slide rod 302 is increased, which facilitates the placement of the injection container 200. When the injection container 200 is placed between the clamping plates 303, the current is controlled to flow through the wire 308 on the surface of the iron core 307, generating magnetism on the surface of the iron core 307. When the power is cut off at 08, the slide bar 302 is reset by the force of the compression spring 304, so that the clamping plate 303 at the end of the slide bar 302 limits the outer wall of the clamping assembly 300. In order to improve the stability of the injection container 200, the direction of the current in the wire 308 is adjusted so that the magnetic pole of the iron core 307 near the magnetic rod 305 is the same as the magnetic rod 305. This causes the end of the magnetic rod 305 to be pushed by the magnetic force, so that the clamping plate 303 fixes the injection container 200, improving the stability of the injection container 200 and reducing the labor intensity of the operators. The output of the control motor 401 drives the lead screw 402 to rotate. During the rotation of the lead screw 402, the pressure plate 403 moves downward in the vertical direction. During the movement of the pressure plate 403, it pushes the piston shaft, thereby realizing quantitative titration. When the drug solution reacts with the analytical solution between the drug solution and the analytical cup, the sensor 103 is used to obtain the mass of the drug solution, thereby improving the accuracy of titration analysis. By controlling the piston rod at the end of the cylinder 512, the base plate 513 is driven to move downward in the vertical direction. The base plate 513 pushes the pedal 508 to move downward repeatedly. During the downward movement of the moving rod 506, the protrusion 510 slides on the inner wall of the arc groove 509, thereby causing the moving rod 506 to rotate during the downward movement. The moving rod 506 drives the stirring blade 507 to move vertically along the inside of the analysis cup. When the stirring blade 507 moves downward and rotates, it stirs the drug solution dripped into the analysis cup in real time, thereby obtaining the titration result of the drug solution in real time. When the drug solution titration is finished, the moving rod 506 is stopped. At this time, the moving rod 506 is reset by the force of the elastic element 511, causing the stirring blade 507 to rotate automatically during the upward movement. The drug solution attached to the surface of the stirring blade 507 is detached from the surface of the stirring blade 507 by the centrifugal force, improving the accuracy of drug quantitative analysis.
