Description

Technical Field

[0001] This utility model belongs to the technical field of clinical drug testing equipment, specifically relating to a pharmaceutical drug testing device. Background Technology

[0002] Pharmacy is the healthcare industry that connects health science and chemical science. It is responsible for ensuring the safe and effective use of medicines. Pharmacy mainly studies the source, processing, properties, effects, analysis, identification, dispensing, production and storage of drugs. Its main tasks are to continuously provide more effective drugs and improve drug quality, ensure drug safety, and treat or cure diseases in a way that minimizes harm and maximizes benefits for patients. When conducting pharmaceutical experiments in clinical practice, drugs must be tested to avoid errors in drug use.

[0003] Chinese utility model patent CN216285208U discloses a clinical pharmaceutical biological drug testing device. By controlling the operation of the fan, air is blown into the inner cavity of the dustproof testing chamber through the air outlet plate, and air is simultaneously drawn in through the air suction plate. This causes the air in the inner cavity of the dustproof testing chamber to circulate internally through the inner cavity of the fixed and movable filter tubes. The air filter adsorbs dust in the air, thereby reducing dust in the inner cavity of the dustproof testing chamber and preventing dust from entering the test tubes and affecting the purity of the drugs or blood, thus improving the accuracy of the testing.

[0004] However, the middle part of the test tube in this device is in direct contact with the test tube mounting plate without any protective measures. During the rotation of the test tube mounting plate, the test tube will be subjected to a large pressure, which poses a risk of breakage. In addition, the movable door of the device is located on the front of the dustproof calibration box, which makes it inconvenient to store and retrieve the test tubes, and is not conducive to cleaning, disinfecting and replacing the test tubes. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a pharmaceutical drug testing device that addresses the shortcomings of the prior art. This drug testing device has a simple structure, can effectively protect test tubes, prevent test tube damage, facilitate the storage and retrieval of test tubes, and can be widely applied.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a pharmaceutical drug testing device, characterized in that it includes a box, a base is fixedly installed inside the box, a column is rotatably connected to the base, a turntable is fixedly installed on the column, a plurality of test tube storage slots are evenly opened on the turntable, and elastic clamping components for clamping test tubes are provided on both sides of the test tube storage slots. Test tubes of different outer diameters can be clamped by clamping the test tubes with the elastic clamping components.

[0007] Electric push rods are vertically fixed on both sides of the outer shell of the box. A protective cover is fixedly installed at the top of the output shaft of the electric push rod. A servo motor is fixedly installed on the protective cover. An external spline is provided at the end of the output shaft of the servo motor. An internal spline that mates with the external spline is provided at the top of the column. A dropper is embedded in the protective cover. The drug to be tested is added to the test tube through the dropper.

[0008] Activating the electric actuator raises and lowers the protective cover, causing the external spline to disconnect or connect with the internal spline. When the protective cover descends to its lowest position, the external spline connects with the internal spline, and the servo motor drives the turntable to rotate. The servo motor performs periodic forward and reverse rotations, with a 15-second interval between forward and reverse rotations, which shakes the test tubes in the test tube storage tank to mix the drugs in the test tubes.

[0009] When the protective cover is raised to its highest position, the operator can take out the test tubes from the test tube storage tank or put test tubes into the test tube storage tank.

[0010] The protective cover is also equipped with an air outlet pipe, which is connected to an exhaust fan via a quick connector. When the protective cover is lowered to its lowest position, it seals the box and the exhaust fan removes the dust from inside the box, keeping the inside of the box in a dust-free environment.

[0011] Preferably, the elastic clamping assembly includes two arc-shaped clamping plates, the height of which is not less than half the height of the test tube. A soft pad is provided on the opposite side of the arc-shaped clamping plates to protect the test tube. A sliding rod is fixedly connected to the outer side of the arc-shaped clamping plates and is slidably connected to the turntable. A soft pad is provided at the bottom of the test tube storage slot to protect the test tube. Installation slots are provided on both sides of the test tube storage slot. A spring is provided between the installation slot and the adjacent arc-shaped clamping plate. The sliding rod away from the column extends to the outside of the turntable and is fixedly connected to a handle.

[0012] By pulling the handle outwards along the sliding rod, the outer curved clamping plate moves outwards, allowing the test tube to be placed between the two curved clamping plates. Here, the outer side refers to the side furthest from the column, while the inner side refers to the side closest to the column.

[0013] Preferably, a limiting block is fixedly connected to the end of the sliding rod near the column, and a limiting groove is formed in the turntable. The limiting block is slidably limited and installed in the limiting groove. The inner arc-shaped clamping plate can move towards the limiting groove when squeezed by the test tube. When the test tube moves outward under the action of centrifugal force, the inner arc-shaped clamping plate can continue to stick tightly to the test tube under the action of the spring, stably clamping the test tube. The limiting block slides within the limiting groove to limit the movement of the inner arc-shaped clamping plate, preventing excessive displacement and making it inconvenient to install the test tube.

[0014] Preferably, the outer chord length of the arc-shaped clamping plate is less than the width of the mounting groove, and the height of the arc-shaped clamping plate is less than the height of the mounting groove. The arc-shaped clamping plate can be moved into the mounting groove, which allows the test tube storage groove to have a larger storage space.

[0015] Preferably, a connecting groove is provided on the top of the base, and a plurality of lower hemispherical grooves are evenly provided on the bottom of the connecting groove. A plurality of upper hemispherical grooves are also evenly provided on the bottom of the column. The lower hemispherical grooves correspond one-to-one with the upper hemispherical grooves. A ball is provided between the corresponding upper and lower hemispherical grooves to support the column and reduce the friction between the base and the column.

[0016] Preferably, the bottom periphery of the turntable is rotatably connected to the inner wall of the housing via bearings, thereby improving the stability of the turntable.

[0017] This utility model has the following advantages compared with the prior art: This invention features a protective cover on the casing. An electric push rod drives the protective cover to rise and fall, thereby opening or closing the casing for storing and retrieving test tubes. The rising and falling of the protective cover also enables the disconnection and connection of the servo motor output shaft and the column. The servo motor drives the turntable to perform periodic forward and reverse rotation, ensuring that the drugs in the test tubes are mixed evenly. An elastic clamping assembly is also provided to hold and fix the test tubes, and the elastic clamping assembly is equipped with a soft pad to protect the test tubes and prevent damage.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] like Figures 1-3 As shown, this utility model provides a pharmaceutical drug testing device, including a housing 1, a base 2 fixedly installed inside the housing 1, a column 3 rotatably connected to the base 2, a turntable 4 fixedly installed on the column 3, the column 3 having a convex cross-section to facilitate the installation of the turntable 4, a plurality of test tube storage slots 5 evenly opened on the turntable 4, and elastic clamping components 7 for clamping test tubes 6 provided on both sides of the test tube storage slots 5, the test tubes 6 can be clamped by the elastic clamping components 7, test tubes 6 of different outer diameters can be clamped.

[0026] Electric push rods 8 are vertically fixed on both sides of the outer side of the housing 1. A protective cover 9 is fixedly installed on the top of the output shaft of the electric push rod 8. A servo motor 10 is fixedly installed on the protective cover 9. An external spline 11 is provided on the end of the output shaft of the servo motor 10. An internal spline 12 that mates with the external spline 11 is provided inside the top of the column 3. A dropper 13 is embedded in the protective cover 9. The drug to be tested is added into the test tube through the dropper 13.

[0027] Activating the electric push rod 8 raises and lowers the protective cover 9, causing the outer spline 11 to disconnect or connect with the inner spline 12. When the protective cover 9 descends to its lowest position, the outer spline 11 connects with the inner spline 12, and the servo motor 10 drives the turntable 4 to rotate. The servo motor 10 performs periodic forward and reverse rotations, with a 15-second interval between forward and reverse rotations, which shakes the test tubes 6 in the test tube storage tank 5, thus completing the mixing of the drugs in the test tubes 6.

[0028] When the protective cover 9 rises to its highest position, the operator can take out the test tube 6 from the test tube storage tank 5, or put test tubes into the test tube storage tank 5.

[0029] The protective cover 9 is also equipped with an air outlet pipe 14, which is connected to an exhaust fan via a quick connector. When the protective cover 9 is lowered to its lowest position, the protective cover 9 seals the box 1, and the exhaust fan extracts the dust from the box 1, keeping the box 1 in a dust-free environment.

[0030] In this embodiment, the elastic clamping assembly 7 includes two arc-shaped clamping plates 15. The height of the arc-shaped clamping plates 15 is not less than half the height of the test tube 6. A soft pad is provided on the opposite side of the arc-shaped clamping plates 15 to protect the test tube 6. A sliding rod 16 is fixedly connected to the outer side of the arc-shaped clamping plates 15. The sliding rod 16 is slidably connected to the turntable 4. A soft pad is provided at the bottom of the test tube storage slot 5 to protect the test tube 6. Installation slots 17 are opened on both sides of the test tube storage slot 5. A spring 18 is provided between the installation slot 17 and the adjacent arc-shaped clamping plate 15. The sliding rod 16 away from the column 3 extends to the outside of the turntable 4 and is fixedly connected to a handle. The sliding rod 16 away from the column 3 and the handle are U-shaped for easy operation.

[0031] By pulling the handle outward, the outer sliding rod 16 can be moved outward, causing the outer arc-shaped clamping plate 15 to move outward, thereby placing the test tube 6 between the two arc-shaped clamping plates 15. Here, the outer side refers to the side away from the column 3, and the inner side refers to the side closer to the column 3.

[0032] In this embodiment, a limiting block 19 is fixedly connected to the end of the sliding rod 16 near the column 3. A limiting groove 20 is formed in the turntable 4. The limiting block 19 is slidably limited and installed in the limiting groove 20. The inner arc-shaped clamping plate 15 can move towards the limiting groove 20 when squeezed by the test tube. When the test tube 6 moves outward under the action of centrifugal force, the inner arc-shaped clamping plate 15 can continue to stick tightly to the test tube 6 under the action of the spring 18, stably clamping the test tube 6. The limiting block 19 slides within the limiting groove 20 to limit the movement of the inner arc-shaped clamping plate 15, preventing excessive displacement and making it inconvenient to install the test tube.

[0033] In this embodiment, the outer chord length of the arc-shaped clamping plate 15 is less than the width of the mounting groove 17, and the height of the arc-shaped clamping plate 15 is less than the height of the mounting groove 17. The arc-shaped clamping plate 15 can be moved to the mounting groove 17, which allows the test tube storage groove 5 to have a larger storage space.

[0034] In this embodiment, a connecting groove is provided on the top of the base 2, and a plurality of lower hemispherical grooves are evenly provided on the bottom of the connecting groove. A plurality of upper hemispherical grooves are also evenly provided on the bottom of the column 3. The lower hemispherical grooves correspond one-to-one with the upper hemispherical grooves. A ball bearing 21 is provided between the corresponding upper and lower hemispherical grooves to support the column 3 and reduce the friction between the base 2 and the column 3.

[0035] In this embodiment, the bottom periphery of the turntable 4 is rotatably connected to the inner wall of the housing 1 via bearings, thereby improving the stability of the turntable 4.

[0036] When in use, start the electric push rod 8, which will drive the protective cover 9 to rise. When the protective cover 9 rises to the highest position, the operator can put the test tubes into the test tube storage tank 5.

[0037] By pulling the outer sliding rod 16 outward with the handle, the outer arc-shaped clamping plate 15 is moved outward, so that the test tube 6 can be placed between the two arc-shaped clamping plates 15. Then, the sliding rod 16 is slowly released, and under the action of the spring 18, the arc-shaped clamping plate 15 returns to its original position to clamp the test tube 6.

[0038] Start the electric push rod 8 to drive the protective cover 9 to descend. When the protective cover 9 descends to the lowest position, the outer spline 11 connects with the inner spline 12.

[0039] Turn on the exhaust fan to remove the dust from inside the housing 1, thus maintaining a dust-free environment inside the housing 1.

[0040] Simultaneously, the drug to be tested is added into the test tube through the dropper 13. The servo motor 10 is started to drive the turntable 4 to rotate, so that the next test tube is moved directly below the dropper 13. The drug to be tested is added into the test tube through the dropper 13, and the drug is added into multiple test tubes in sequence.

[0041] After the drugs are added, the servo motor 10 is started. The servo motor 10 can drive the turntable 4 to rotate. The servo motor 10 performs periodic forward and reverse rotation, with a 15-second interval between forward and reverse rotation. This shakes the test tubes 6 in the test tube storage tank 5, thus completing the mixing of the drugs in the test tubes 6.

[0042] After the drugs are mixed, the servo motor 10 is turned off. After 30 seconds, the electric push rod 8 is activated, which raises the protective cover 9. When the protective cover 9 reaches its highest position, the operator can remove the test tubes 6 from the test tube storage tank 5. The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on the utility model. Any simple modifications, alterations, and equivalent changes made to the above embodiments based on the technical essence of the utility model shall still fall within the protection scope of the technical solution of this utility model.
