Abstract
Description
Technical Field
[0001] This invention relates to the field of reagent mixing technology, and in particular to a reagent mixing device for pharmaceutical testing. Background Technology
[0002] As a core auxiliary device in the pharmaceutical and testing fields, the reagent mixing device for pharmaceutical testing is widely used in pharmaceutical companies for drug quality control, third-party testing institutions for sample analysis, and research institutions for drug development. In the pharmaceutical testing process, the accuracy of reagent mixing directly determines the validity of the test data.
[0003] Traditional mixing methods often rely on manual shaking or simple mechanical stirring. The high shear force of machine stirring can damage the structure of the active ingredients in the solvent. Emulsion solvents and suspension drug solvents are typical examples that cannot be effectively fused by machine stirring and must rely on shaking. Mechanical stirring can easily damage the emulsion film on the surface of the emulsion droplets, resulting in large fluctuations in the data of the same batch of test samples. In addition, reagent mixing often relies on manual pouring or a single simple adjustment structure to control the amount of reagents, which makes it difficult to match the reagent ratio required for the test and may even lead to misjudgment. Therefore, it is necessary to propose a reagent mixing device for drug testing. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as traditional mixing methods that rely heavily on manual shaking or simple mechanical stirring, where the high shear force of machine stirring can damage the structure of the active ingredients in the solvent, and where emulsion solvents and suspension solvents are typical examples of substances that cannot be effectively fused by machine stirring and must rely on shaking, and where mechanical stirring can easily damage the emulsion film on the surface of the emulsion droplets, leading to large fluctuations in the data of the same batch of test samples, and where reagent mixing often relies on manual pouring or a single simple adjustment structure to control the amount of reagents. Therefore, this invention proposes a reagent mixing device for pharmaceutical testing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pharmaceutical testing reagent mixing device includes a base plate and a U-shaped support plate disposed on the base plate. The U-shaped support plate is provided with at least two sets of transparent test tubes, and an output hole is opened on the outer side of the transparent test tubes. The U-shaped support plate is equipped with a movable plate and a threaded adjusting rod. A sealing column and a sealing plate are fixedly connected to the upper part of the movable plate. The sealing plate is adapted to the output hole. By pressing the movable plate or rotating the threaded adjusting rod, the sealing plate can be driven to move to adjust the output of the output hole. A mixing container is provided below the U-shaped support plate, and a first servo motor is provided on the base plate. The output shaft of the first servo motor is fixedly connected to a rotating rod. The rotating rod is connected to the mixing container through a first traction rope and can drive the mixing container to shake.
[0006] An output hose is fixedly connected to the outside of the mixing container.
[0007] The above technical solution further includes:
[0008] Preferably, an output tube is fixedly connected to the outside of the output hole of the transparent test tube, and the size of the output tube is adapted to the size of the output hole.
[0009] Preferably, a first reset spring is provided between the movable plate and the U-shaped support plate. There are two sets of the first reset springs. The first reset springs can drive the movable plate to reset so that the sealing plate closes the output hole.
[0010] Preferably, the threaded adjusting rod and the movable plate are threadedly connected, and the movable plate is slidably connected to the first limiting rod.
[0011] Preferably, a converging hollow horizontal plate is fixedly connected to the outer side of multiple sets of output pipes, and a liquid outlet pipe is fixedly connected to the lower part of the converging hollow horizontal plate. Multiple sets of second return springs are fixedly connected to the outer side of the liquid outlet pipe. The number of second return springs is four, and the end of the multiple sets of second return springs away from the liquid outlet pipe is fixedly connected to the mixing container.
[0012] Preferably, the mixing container is provided with a V-shaped plate, and a traction crossbar is fixedly connected to the end of the V-shaped plate away from the mixing container. The outer side of the traction crossbar is fixedly connected to the first traction rope.
[0013] Preferably, a second servo motor is fixedly connected to the side of the U-shaped support plate near the base plate, and a bidirectional lead screw is fixedly connected to the end of the output shaft of the second servo motor.

[0014] Preferably, a connecting horizontal plate is fixedly connected to the side of the U-shaped support plate near the plate, and a second limiting rod is fixedly connected to the inner side of the connecting horizontal plate, and the threads at both ends of the bidirectional lead screw have opposite directions.

[0017] The present invention has the following beneficial effects: In this invention, by setting a pressable movable plate and a rotatable threaded adjustment rod, and cooperating with a sealing plate on the movable plate that matches the output hole, two reagent output adjustment methods can be realized. According to the reagent ratio required for drug testing, the outflow of reagents in at least two sets of transparent test tubes can be controlled, avoiding poor mixing effect due to dosage deviation, reducing reagent waste, and ensuring the accuracy of reagent ratio in the early stage of testing.

[0021] 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. Example
[0022] like Figures 1-10 As shown, the present invention proposes a drug testing reagent mixing device, which includes a base plate 1 and a U-shaped support plate 2 disposed on the base plate 1. At least two sets of transparent test tubes 3 are provided on the U-shaped support plate 2, and an output hole 303 is opened on the outside of the transparent test tubes 3. The U-shaped support plate 2 is equipped with a movable plate 4 and a threaded adjusting rod 5. The upper part of the movable plate 4 is fixedly connected with a sealing column 402 and a sealing plate 403. The sealing plate 403 is adapted to the output hole 303. By pressing the movable plate 4 or rotating the threaded adjusting rod 5, the sealing plate 403 can be driven to move to adjust the output of the output hole 303. A mixing container 702 is provided below the U-shaped support plate 2, and a first servo motor 901 is provided on the base plate 1. The output shaft of the first servo motor 901 is fixedly connected to a rotating rod 902. The rotating rod 902 is connected to the mixing container 702 through a first traction rope 8, which can drive the mixing container 702 to shake. An output hose 13 is fixedly connected to the outside of the mixing container 702.
[0023] Furthermore, the different reagents to be mixed are respectively placed into at least two sets of transparent test tubes 3 on the U-shaped support plate 2. When reagent mixing is required, if the reagent flow rate needs to be adjusted, the sealing plate 403 adapted to the output hole 303 can be displaced by pressing the moving plate 4 or rotating the threaded adjusting rod 5, thereby changing the opening size of the output hole 303 and controlling the output amount of reagent in each transparent test tube 3. The sealing column 402 helps to ensure the sealing and flow stability of the reagent flow during the adjustment process. Subsequently, the reagent flowing out of each transparent test tube 3 directly enters the mixing container 702 below, waiting for the reagent to be mixed. After all the reagents are put into the mixing container 702, the first servo motor 901 on the base plate 1 is started. The output shaft of the first servo motor 901 drives the rotating rod 902 to rotate. The rotating rod 902 generates a traction force on the mixing container 702 through the first traction rope 8, causing the mixing container 702 to shake, thereby allowing the different reagents inside to be fully mixed evenly (emulsion solvent and suspension drug solvent). After the mixing is completed, the mixed drug test reagents are discharged through the output hose 13 on the outside of the mixing container 702 for use in subsequent test steps.
[0024] An output tube 304 is fixedly connected to the outside of the output hole 303 of the transparent test tube 3. The size of the output tube 304 is compatible with the size of the output hole 303.
[0025] Furthermore, the reagent flowing out of the output port 303 will enter the output tube 304 that is adapted to its size. The output tube 304 can play a stable guiding role for the reagent, preventing leakage or deviation of the flow direction during the delivery process, and ensuring that the reagent flows into the mixing container 702 below.
[0026] A first reset spring 401 is provided between the movable plate 4 and the U-shaped support plate 2. There are two sets of first reset springs 401. The first reset springs 401 can drive the movable plate 4 to reset so that the sealing plate 403 closes the output hole 303.
[0027] Furthermore, when it is necessary to allow the reagent in the transparent test tube 3 to flow out, pressing the moving plate 4 will cause the moving plate 4 to move towards the U-shaped support plate 2. At this time, the two sets of first reset springs 401 will be compressed and store elastic potential energy. Simultaneously, the moving plate 4 will cause the sealing plate 403 to disengage from the output hole 303, allowing the reagent to flow out from the output hole 303. When it is no longer necessary for the reagent to flow out and the pressing of the moving plate 4 is stopped, the two sets of first reset springs 401 will release the stored elastic potential energy, generating a reverse thrust to drive the moving plate 4 back to its initial position. The moving plate 4 will simultaneously cause the sealing plate 403 to re-fit tightly against the output hole 303, achieving the sealing of the output hole 303 and preventing continuous reagent leakage. Moreover, the two sets of first reset springs 401 can make the moving plate 4 bear force evenly, ensuring the sealing and stability of the sealing plate 403 after reset.
[0028] The threaded adjusting rod 5 and the movable plate 4 are threadedly connected, and the movable plate 4 is slidably connected to the first limiting rod 501.
[0029] Furthermore, rotating the threaded adjusting rod 5 is another way to adjust the reagent flow rate in the transparent test tube 3. Since the threaded adjusting rod 5 is threadedly connected to the moving plate 4, its rotational motion can be converted into the linear motion of the moving plate 4. During this process, the moving plate 4 slides with the first limiting rod 501. The first limiting rod 501 can restrict the moving plate 4 from rotating with the threaded adjusting rod 5, ensuring that the moving plate 4 only makes a stable linear displacement along the axial direction of the first limiting rod 501. When the threaded adjusting rod 5 rotates in the forward direction, the moving plate 4 moves towards the U-shaped support plate 2, causing the sealing plate 403 to disengage from the output hole 303, providing a channel for reagent flow. The first limiting rod 501 can ensure the accurate displacement direction of the moving plate 4, preventing the sealing plate 403 from being misaligned with the output hole 303. When the threaded adjusting rod 5 rotates in the reverse direction, the moving plate 4 moves away from the U-shaped support plate 2. As the support plate 2 moves in the direction of the sealing plate 403, the sealing plate 403 gradually approaches and finally fits against the output hole 303, thereby sealing the output hole 303. Meanwhile, the first limiting rod 501 always maintains the stable displacement of the moving plate 4, ensuring that the sealing effect of the sealing plate 403 on the output hole 303 is stable.
[0030] Multiple sets of output pipes 304 are fixedly connected to a converging hollow horizontal plate 6 on their outer sides. A liquid outlet pipe 7 is fixedly connected to the lower part of the converging hollow horizontal plate 6. Multiple sets of second reset springs 701 are fixedly connected to the outer side of the liquid outlet pipe 7. There are four sets of second reset springs 701. The end of the multiple sets of second reset springs 701 away from the liquid outlet pipe 7 is fixedly connected to the mixing container 702.
[0031] Furthermore, the different pharmaceutical reagents flowing from the multiple output pipes 304 first enter the commonly connected hollow converging plate 6. The hollow converging plate 6 can concentrate and gather the reagents flowing out of the multiple output pipes 304, preventing the reagents from being dispersed and lost during transportation. Subsequently, the gathered reagents are guided into the mixing container 702 through the liquid outlet pipe 7 at the bottom of the hollow converging plate 6. The liquid outlet pipe 7 can ensure that the reagents are stably delivered to the designated area of the mixing container 702, preventing reagents from overflowing or deviating from their flow direction. When the first servo motor 901 drives the mixing container 702 to shake to mix the reagents via the first traction rope 8, the mixing container... 702 will pull the four sets of second reset springs 701 on the outside. During the process of being subjected to force, the four sets of second reset springs 701 will generate elastic deformation. On the one hand, it can buffer the impact force when the mixing container 702 is shaken, and prevent the mixing container 702 from being damaged due to excessive shaking amplitude or uneven force. On the other hand, after the shaking of the mixing container 702 stops, it can use its own elastic restoring force to pull the mixing container 702 back to the initial position quickly. Moreover, the symmetrical arrangement of the four sets of second reset springs 701 can ensure that the force on the mixing container 702 is uniform when it is reset, and ensure that the docking state between the liquid outlet pipe 7 and the mixing container 702 is stable after reset, without affecting the subsequent reagent delivery.
[0032] A V-shaped plate 703 is provided on the mixing container 702. A traction crossbar 704 is fixedly connected to one end of the V-shaped plate 703 away from the mixing container 702. The outer side of the traction crossbar 704 is fixedly connected to the first traction rope 8.
[0033] Furthermore, the tension of the first traction rope 8 will directly act on the traction crossbar 704, causing the traction crossbar 704 to move synchronously. The traction crossbar 704 is fixedly connected to the V-shaped plate 703. Its movement will transmit the tension to the V-shaped plate 703. The V-shaped plate 703 is set on the mixing container 702, which can stably transmit the force from the traction crossbar 704 to the mixing container 702, thereby causing the mixing container 702 to shake.
[0034] A second servo motor 10 is fixedly connected to the side of the U-shaped support plate 2 near the base plate 1. A bidirectional lead screw 11 is fixedly connected to the end of the output shaft of the second servo motor 10. An arc-shaped clamping plate 1102 is provided on the bidirectional lead screw 11. There are two sets of arc-shaped clamping plates 1102.
[0035] A connecting horizontal plate 9 is fixedly connected to the side of the U-shaped support plate 2 near the plate 1. A second limiting rod 1101 is fixedly connected to the inner side of the connecting horizontal plate 9. The threads at both ends of the bidirectional lead screw 11 are in opposite directions.
[0036] Furthermore, the second servo motor 10 on the side of the U-shaped support plate 2 near the base plate 1 is activated. The output shaft of the second servo motor 10 drives the bidirectional lead screw 11 at the end to rotate synchronously. Due to the thread characteristics of the bidirectional lead screw 11, its rotation drives the two sets of bow-shaped clamping plates 1102 to move in opposite directions along the axial direction of the bidirectional lead screw 11, gradually approaching the outer wall of the mixing container 702. When the two sets of bow-shaped clamping plates 1102 are tightly attached to the outer wall of the mixing container 702, the second servo motor 10 stops running. The two sets of bow-shaped clamping plates 1102 securely fix the mixing container 702 through symmetrical clamping action, preventing the mixing container 702 from shifting due to reagent impact when receiving reagents. When it is necessary to remove the mixing container 702 or adjust its position, the output shaft of the second servo motor 10 is controlled to rotate in the opposite direction, driving the bidirectional lead screw 11 to rotate in the opposite direction, so that the two sets of bow-shaped clamping plates 1102 move in opposite directions along the axial direction of the bidirectional lead screw 11, gradually moving away from the mixing container 702, thus releasing the clamping and fixing of the mixing container 702.
[0037] The transparent test tube 3 is equipped with a graduated strip 301 and a screw cap 302 at the top.
[0038] Furthermore, when loading the reagents to be mixed into the transparent test tube 3, the staff can visually observe the reagent level through the graduation strip 301 on the transparent test tube 3, control the loading amount of each reagent, and ensure that different reagents are injected into the transparent test tube 3 in the required proportion or dosage for the test. This avoids the subsequent mixing effect and test results being affected by the reagent dosage deviation. After the reagents are loaded, the screw cap 302 at the top of the transparent test tube 3 is tightened clockwise to seal the opening of the transparent test tube 3, preventing the reagents inside from coming into contact with air and evaporating, oxidizing, or being contaminated by external dust or impurities, thus ensuring the purity and stability of the reagents during storage and waiting for them to flow out. When it is necessary for the reagents in the transparent test tube 3 to flow out through the outlet hole 303, the screw cap 302 is then unscrewed counterclockwise to prevent it from obstructing the smooth flow of the reagents to the outlet hole 303 under the action of gravity.
[0039] The U-shaped support plate 2 is provided with a T-shaped connecting plate 201. The upper part of the mixing container 702 is fixedly connected with a second traction rope 12. There are two sets of the second traction rope 12. The end of the second traction rope 12 away from the mixing container 702 is fixedly connected to the converging hollow horizontal plate 6.
[0040] Furthermore, during device operation, the T-shaped connecting plate 201 on the U-shaped support plate 2 provides auxiliary support and positioning for the transparent test tube 3, ensuring that the transparent test tube 3 maintains a stable posture when reagents are loaded, reagents flow out, or the device vibrates slightly, preventing misalignment of the output hole 303 and the sealing plate 403 or premature reagent leakage due to test tube shaking. At the same time, the two sets of second traction ropes 12 on the upper part of the mixing container 702 form a flexible restraint on the mixing container 702 from the top when the mixing container 702 is pulled and shaken by the first traction rope 8, together with the second reset spring 701 at the bottom, to limit the shaking amplitude of the mixing container 702, preventing the internal reagent from overflowing due to excessive shaking. During the reset process of the mixing container 702, the two sets of second traction ropes 12 can provide symmetrical tension.
[0041] In this embodiment, the specific implementation method is as follows: First, the different drug test reagents to be mixed are respectively loaded into at least two sets of transparent test tubes 3 on the U-shaped support plate 2, which are supported and positioned by the T-shaped connecting plate 201. The staff accurately controls the loading amount of each reagent through the scale strip 301 on the transparent test tube 3. After loading, the screw cap 302 at the top of the transparent test tube 3 is tightened clockwise to achieve a seal. When the reagent needs to flow out, the screw cap 302 is first unscrewed counterclockwise. Then, by pressing the moving plate 4, the two sets of first reset springs 401 are compressed or the threaded adjusting rod 5 threadedly connected to the moving plate 4 is rotated. Under the action of the first limiting rod 501 restricting the rotation of the moving plate 4 and ensuring its stable linear displacement, the sealing plate 403 is driven to disengage from the output hole 303. The sealing column 402 helps to ensure the seal. The reagent flows from the output hole 303 into the output tube 304 of the appropriate size. After being collected by the converging hollow horizontal plate 6 connected by multiple sets of output tubes 304, it flows accurately into the mixing container 702 below through the liquid outlet pipe 7. At the same time, the U-shaped support plate 303 is activated. The second servo motor 10 on the side of the support plate 2 near the base plate 1 drives the bidirectional lead screw 11 to rotate, causing the two sets of bow-shaped clamping plates 1102 to move towards each other along the bidirectional lead screw 11 and clamp the mixing container 702 to prevent displacement. After all the required reagents have entered the mixing container 702, the bidirectional lead screw 11 is rotated in the opposite direction, and the two sets of bow-shaped clamping plates 1102 are released from locking the mixing container 702. The first servo motor 901 on the base plate 1 is then started, and its output shaft drives the rotating rod 902 to rotate. The first traction rope 8 pulls the V-shaped clamping plate on the mixing container 702. The traction crossbar 704 fixed by the shape plate 703 causes the mixing container 702 to shake. During the shaking process, the two sets of second traction ropes 12 on the upper part of the mixing container 702 and the four sets of second return springs 701 on the outside of the liquid outlet pipe 7 together limit the shaking amplitude and buffer the impact force. After the mixing is completed, the second servo motor 10 is controlled to rotate in the opposite direction to make the bow-shaped clamping plate 1102 release the mixing container 702. The four sets of second return springs 701 and the two sets of second traction ropes 12 together drive the mixing container 702 to return to its original position. Finally, the mixed reagent is discharged through the output hose 13 on the outside of the mixing container 702 for subsequent testing.
[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
