Description

Technical Field

[0001] The present application belongs to the field of medical drug testing technology, and in particular relates to a drug inspection and detection device. Background Art

[0002] Drug ingredient testing is a key step in ensuring drug quality and drug safety. Traditional testing processes rely on manual operations to prepare and dispense test fluids, resulting in low efficiency and difficulty in controlling errors.

[0003] 1. The operation process is cumbersome and time-consuming: In the existing technology, after the test personnel complete the overall weighing of the drug powder, in order to prevent excessive addition of drug powder at one time, which will cause agglomeration and wall sticking, the operator needs to add the entire drug powder to the mixed solvent in small amounts multiple times. The operator also needs to change the stirring speed according to the amount of drug powder added at a time to ensure the uniformity of the mixing. As a result, in a single test, a lot of time is spent in the process of preparing the drug mixed test solution, making it difficult to meet the needs of rapid screening of large quantities of samples.

[0004] 2. Poor mixing uniformity leads to detection errors: Manual stirring relies on the operator's experience, which is prone to problems such as powder agglomeration and uneven solvent mixing, resulting in fluctuations in the concentration of the test solution, which significantly affects the accuracy of the subsequent color development reaction.

[0005] Therefore, developing a drug inspection and testing device that is easy to operate and can achieve quantity control and mixing has become the key to solving the pain points of existing technologies. Utility Model Content

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The quantitative delivery of pharmaceutical powder is achieved through the mechanical linkage of the blanking roller and the regulating component, and the synchronous stirring of the mixing roller ensures the uniformity of the test liquid.

[0019] 1. Intermittent Blanking: The blanking roller at the bottom of the conical silo rotates driven by the drive shaft, pushing the powder into the ring silo of the control assembly. The undulating ring grooves within the ring silo, which define the guide seat, cooperate with the T-ring of the adjusting link to cause the valve plug to slide up and down as the drive shaft rotates. The highest point of the ring groove corresponds to the lowest point of the valve plug, opening the blanking port; the lowest point corresponds to the valve plug closed. This allows the powder to be intermittently dropped into the mixing silo at a preset frequency, preventing agglomeration or uneven mixing caused by a large amount of powder being dropped at once.

[0020] 2. Matching the drop rate with the stirring rate: The drive shaft transmits power to the mixing roller synchronously through the transmission assembly (slide, cross lock, and return spring). The drop rate and stirring speed are coordinated in real time. For example, when the mixing roller rotates at high speed, the valve plug sliding frequency increases, and the drop rate increases simultaneously, ensuring that the powder and solvent are always in a dynamically balanced mixing state in the mixing chamber, improving the uniformity of the test liquid.

[0021] 3. Parallel rack operation: Multiple racks arranged on the test platform can simultaneously hold multiple test pens, enabling simultaneous preparation and dispensing of test solutions for multiple samples, reducing waiting time for processing individual samples. For example, in pharmaceutical batch testing, multiple samples (the specific number depends on the rack density) can be processed in parallel. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0033] See Figures 1 to 8 As shown, the drug inspection and testing device provided in the present application includes a testing platform 1, on which a plurality of placement racks 2 are arranged, on which a testing pen 3 is placed, and the testing pen 3 includes a preparation mechanism, a motor 4 is provided at the top of the preparation mechanism and a dripping assembly is connected to the bottom through a regulating valve 10.

[0034] When testing for relevant components of a drug, the drug sample to be tested is first weighed as a whole and ground into powder. After grinding, all the drug powder is placed in the preparation mechanism. At the same time, a corresponding amount of solvent is injected into the preparation mechanism according to the weight of the drug sample. The motor 4 is started to drive the preparation mechanism so that the drug powder and the solvent are fully mixed to prepare a uniform test solution.

[0035] After the test solution is prepared, it is delivered to the drip assembly via the control valve 10. The tester then drips the test solution onto the test strip corresponding to the drip assembly position on the test stage 1 as needed. The test strip quickly absorbs the test solution, and the color change is immediately apparent. The principle and process of using the test strip to detect drug ingredients are prior art and will not be further described here.

[0036] It should be noted that by providing multiple placement racks 2 and detection pens 3, multiple groups of detection liquids can be prepared simultaneously during the process of preparing and testing detection liquids with different components, thereby improving the detection efficiency of different types of drug components.

[0037] Among them, the preparation mechanism includes a blanking bin 5 and a mixing bin 6, which are connected by threads. A conical bin 7 is fixedly arranged in the blanking bin 5, and a regulating component 8 is arranged at the end of the conical bin 7 away from the motor 4. A blanking roller 14 is rotated by the regulating component 8 in the conical bin 7, and a drive shaft 15 is fixed on the axis of the blanking roller 14. The top end of the drive shaft 15 is connected to the motor 4 and the bottom end passes through the regulating component 8 and is provided with a transmission component 9. The transmission component 9 is connected to the mixing roller 96 arranged in the mixing bin 6.

[0038] When adding drug powder to the feeding bin 5 and solvent to the mixing bin 6, the feeding bin 5 and the mixing bin 6 are in a separated state. The tester pours a sufficient amount of drug powder into the conical feeding bin 7 through the feeding port of the feeding bin 5, and pours a sufficient amount of the test mixed solvent into the mixing bin 6 at once. After completing the addition of drug powder and mixed solvent, the feeding bin 5 and the mixing bin 6 are then screwed together.

[0039] A placement slot is provided on the placement rack 2 . After the blanking bin 5 and the mixing bin 6 are connected, the detection pen 3 is vertically inserted into the placement rack 2 through the placement slot.

[0040] After completing the placement of the detection pen 3, the staff starts the motor 4, and the motor 4 drives the driving shaft 15 to rotate. While rotating, the driving shaft 15 drives the blanking roller 14 to rotate. The blanking roller 14 rotates in the conical silo 7 to push the drug powder evenly to the regulating component 8. The regulating component 8 then allows the drug powder to fall into the mixing bin 6. The drug powder and the solvent falling into the mixing bin 6 are quickly stirred by the rotating mixing roller 96 to form a uniform detection liquid, ensuring the mixing effect.

[0041] After the blanking bin 5 and the mixing bin 6 are tightened, the transmission assembly 9 transmits the rotational power of the drive shaft 15 to the mixing roller 96, ensuring that the mixing roller 96, the drive shaft 15, and the regulating assembly 8 start synchronously, avoiding the agglomeration and wall adhesion of the drug powder, and promoting the drug powder and solvent in the mixing bin 6 to quickly reach a uniform state under the stirring of the mixing roller 96.

[0042] Optionally, the regulating component 8 includes a ring bin, which is arranged at the bottom of the conical silo 7 and is connected to the conical silo 7. A first fixed ring frame 81 is fixedly arranged at one end of the ring bin near the conical silo 7. The upper part of the first fixed ring frame 81 is fixedly connected to the inner ring of the first bearing 82, and the outer ring of the first bearing 82 is fixedly connected to the blanking roller 14. The lower part of the first fixed ring frame 81 is fixedly provided with one end of a limiting guide seat 85. A ring groove is provided at the bottom of the other end of the limiting guide seat 85, and the ring groove is undulating along the periphery of the bottom of the limiting guide seat 85. One end of an adjusting link 83 is rollingly arranged in the ring groove, and the other end of the adjusting link 83 is fixedly set on the valve plug 84. The valve plug 84 is slidingly sealed in the ring bin. The drive shaft 15 passes through the first fixed ring frame 81 and the limiting guide seat 85 and is slidingly connected to the valve plug 84, and the drive shaft 15 passes through the valve plug 84.

[0043] In this embodiment, the rotation of the blanking roller 14 cooperates with the conical silo 7 to uniformly discharge the pharmaceutical powder into the annular silo. The drive shaft 15 drives the blanking roller 14 and simultaneously rotates the valve plug 84. During this rotation, the drive shaft 15 does not drive the first fixed ring frame 81 and the limiting guide seat 85 to rotate. During this rotation, the valve plug 84 drives the adjustment link 83 to roll within the annular groove. The adjustment link 83 rolls within the undulating annular groove, causing the valve plug 84 to slide up and down relative to the annular silo. Specifically, when the adjustment link 83 rolls to the top of the annular groove, the valve plug 84 slides down relative to the annular silo to the lowest point, and vice versa. When it reaches the lowest point, the valve plug 84 opens the annular silo outlet, allowing the pharmaceutical powder to flow smoothly into the mixing silo 6. Otherwise, the outlet is closed. This method is used to control the intermittent dropping of pharmaceutical powder, ensuring that the powder and solvent are fully mixed in the mixing chamber 6, avoiding uneven mixing due to excessive powder. At the same time, since the mixing roller 96 and the valve plug 84 both rotate with the drive shaft 15, the dropping rhythm of the valve plug 84 matches the rotation speed of the mixing roller 96, achieving the coordination of the dropping frequency and the stirring rate, ensuring the stability and consistency of each mixing process, and improving the preparation efficiency and quality of the test liquid.

[0044] The drive shaft 15 has a circumferential limit groove on its surface near the valve plug 84. The valve plug 84 has a circumferential limit groove on its inner surface. The limit groove slides within the limit groove, allowing the valve plug 84 to rotate synchronously with the drive shaft 15 while also allowing the valve plug 84 to slide up and down relative to the drive shaft 15. Furthermore, the first bearing 82 ensures that the first fixed ring 81 and the limit guide seat 85 are fixed during the rotation of the drive shaft 15, thereby not affecting the vertical movement of the valve plug 84.

[0045] It should be noted that when putting the drug powder into the conical silo 7 through the feed port, the connection status of the valve plug 84 and the ring silo should be checked in advance to ensure that the valve plug 84 and the ring silo are in a sealed state to prevent leakage during the process of putting in the drug powder and affecting the mixing ratio.

[0046] Optionally, a limiting ring platform is provided in the annular groove, and a T-shaped ring is provided at one end of the adjusting connecting rod 83 in the annular groove, and the T-shaped ring is clamped in the limiting ring platform.

[0047] In this embodiment, the combination of the T-ring and the limiting ring effectively prevents the adjusting link 83 from falling out of the groove when rolling in the ring groove, ensuring that the adjusting link 83 always moves within the predetermined trajectory. The undulating design of the ring groove allows the valve plug 84 to slide down to the lowest point when the adjusting link 83 rotates to the highest point of the undulation, opening the ring bin outlet, allowing the powder to flow smoothly into the mixing bin 6; conversely, the valve plug rises to close the outlet, achieving intermittent feeding control of the pharmaceutical powder. This design not only improves the uniformity of powder flow, but also optimizes the mixing effect of the powder and solvent through the reciprocating feeding control of the valve plug, ensuring the efficiency and stability of each mixing process, and further improving the preparation quality of the test liquid.

[0048] Optionally, the transmission assembly 9 includes a slide 91, which is slidably sleeved on the outside of the drive shaft 15. A cross lock buckle 93 is fixedly provided at the bottom of the slide 91. A reset spring 92 is provided between the cross lock buckle 93 and the circular ring fixed on the drive shaft 15. A cross lock seat 94 is clamped on the cross lock buckle 93. A second fixed ring frame 95 is fixedly provided in the mixing chamber 6. The cross lock seat 94 is rotatably provided in the second fixed ring frame 95 through a second bearing and its bottom end is fixedly connected to the mixing roller 96.

[0049] In this embodiment, when tightening the blanking bin 5 and the mixing bin 6, the inspector first inserts the cross lock buckle 93 into the cross lock seat 94, and then rotates the blanking bin 5 after completing the insertion, so that the blanking bin 5 and the mixing bin 6 are connected through threaded locking.

[0050] During the rotation of the blanking bin 5, the blanking bin 5 will slide downward relative to the mixing bin 6. During the downward sliding process, the drive shaft 15 slides downward in the slide cylinder 91 and compresses the return spring 92. After the blanking bin 5 and the mixing bin 6 are completely locked, the elastic force provided by the return spring 92 causes the cross lock buckle 93 to tightly engage in the cross lock seat 94 to ensure a stable connection.

[0051] Optionally, a vertical limit rail is provided at one end of the drive shaft 15 near the slide 91, and a vertical limit platform is provided on the inner wall of the slide 91. The limit platform slides within the vertical limit rail. The cooperation between the vertical limit rail and the limit platform ensures that the slide 91 can only slide up and down relative to the drive shaft 15, preventing axial rotation. Therefore, the rotation of the drive shaft 15 is transmitted to the mixing roller 96, ensuring the rotational stability of the mixing roller 96.

[0052] Optionally, the regulating valve 10 includes a valve chamber 101, which is fixedly arranged at the end of the mixing chamber 6. A valve ring 102 is fixedly arranged at one end of the valve chamber 101 close to the mixing chamber 6. A wedge-shaped valve port is opened through the middle of the valve ring 102, and a valve platform 104 is movably arranged in the valve port. A connecting ring frame 103 is provided at the end of the valve platform 104 away from the mixing chamber 6. The connecting ring frame 103 is slidingly sealed and arranged in the valve chamber 101. An adjusting spring 105 is provided between the connecting ring frame 103 and the valve ring 102. The connecting ring frame 103 is also connected to the dripping assembly.

[0053] In this embodiment, after completing the preparation of the mixed detection liquid, the detection personnel pushes the dripping assembly upward to slide. During the upward sliding process, the dripping assembly drives the connecting ring frame 103 to slide upward and compresses the adjusting spring 105. When the connecting ring frame 103 slides upward, it drives the valve platform 104 upward to separate from the wedge-shaped valve port. At this time, the mixed detection liquid flows into the dripping assembly through the wedge-shaped valve port.

[0054] After the amount of test liquid required by the dripping assembly reaches the test requirement, the tester releases the dripping assembly, and the connecting ring frame 103 returns to its original position and slides down under the action of the adjustment spring 105, and the valve platform 104 re-seals the wedge-shaped valve port to ensure that the mixed test liquid no longer flows out. The shape of the valve platform 104 matches the shape of the wedge-shaped valve port.

[0055] Optionally, the dripping assembly includes a dripping tube 11, the top of which is slidably arranged in the valve compartment 101 and connected to the connecting ring frame 103, a rubber hose 16 is arranged in the dripping tube 11, and a dripping port 13 is arranged at the bottom of the dripping tube 11, which is connected to the rubber hose 16.

[0056] In this embodiment, the mixed detection liquid flowing into the dripping assembly falls into the rubber hose 16. Squeezing the rubber hose 16 can control the speed of the mixed detection liquid dripping from the dripping port 13, thereby adjusting the amount of the mixed detection liquid dripping on the test paper to ensure the accuracy of the test results.

[0057] Optionally, the drip assembly further includes an observation window 17 provided on the inner wall of the drip tube 11. The observation window 17 is provided with scale marks, which facilitates the inspection personnel to observe the liquid level of the mixed detection liquid in the rubber hose 16 and further control the dripping amount of the mixed detection liquid.

[0058] Optionally, a control component 12 is provided in the observation window 17, and the control component 12 includes a push rod 121, which is fixed in the observation window 17. A pressure rod 122 and one end of a shift rod 123 are rotatably provided at both ends of the push rod 121, and the other end of the pressure rod 122 is in contact with the rubber hose 16, and the other end of the shift rod 123 abuts against the surface of the pressure rod 122.

[0059] Optionally, when the prepared mixed test liquid needs to flow into the rubber hose 16, the staff member pushes the push rod 121 in the direction close to the valve chamber 101, causing the drip tube 11 to slide upward, thereby disengaging the valve platform 104 from the wedge-shaped valve opening and allowing the mixed test liquid to flow smoothly into the rubber hose 16. Simultaneously, pressing the lever 123 causes the pressure rod 122 to slightly compress the rubber hose 16. The squeezed inner diameter of the rubber hose 16 shrinks, generating pressure, causing the mixed test liquid to drip from the dripping port 13 onto the test paper. The connection between the pressure rod 122 and the lever 123 and the push rod 121 is equipped with a torsion spring to facilitate the reset of the lever 123 and the pressure rod 122 after releasing the lever 123.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
