Description

Technical Field

[0001] This invention relates to the field of pharmaceutical bottle testing technology, specifically a clarity testing instrument. Background Technology

[0002] In the pharmaceutical manufacturing field, clarity is one of the key indicators for measuring drug quality, and its test results are directly related to the safety and efficacy of the drug. Furthermore, according to pharmacopoeia regulations and standard operating procedures, the corresponding illuminance range for testing differs for different types of injectable preparations, and the sampling quantity per batch also varies for different specifications of injectable preparations. When using the instrument, turn on the power and the fluorescent light. Move the illuminance meter and use the illuminance display to determine the position that meets the illuminance requirements for testing. Then, gently shake the drug bottle and place it in the corresponding position on the clarity detector for visual inspection. During the inspection, the drug bottle needs to be tested in three steps: upright, horizontal, and inverted.

[0003] However, existing clarity testing devices have significant drawbacks: the testing process requires manually handling the reagent bottle, necessitating repeated movement to find the optimal light exposure position, and the same adjustment procedure must be repeated for the same batch of bottles. This method is prone to inconsistencies in testing standards due to human error, thus affecting the accuracy and reliability of the test results and increasing the difficulty of reagent quality control. Summary of the Invention

[0004] The purpose of this invention is to provide a clarity detector to solve the problems of cumbersome operation, low efficiency and inconsistent testing standards when testing the same batch of medicine bottles with existing detectors.

[0005] To achieve the above objectives, the technical solution provided by the present invention is as follows:

The lifting mechanism and the telescopic drive mechanism are respectively provided with a first marking component and a second marking component with identical structures. When the detector tests the first medicine bottle of the same batch, it slides the medicine holder to the optimal testing position via the lifting mechanism and the telescopic drive mechanism, and then marks the height and horizontal position of the medicine holder using the first marking component and the second marking component, respectively.

An elastic squeezing post is slidably connected to the mounting block. After the medicine placement component moves laterally into position, the elastic squeezing post is pressed, causing the elastic squeezing post to push the positioning post, so that the elastic limiting ring is engaged within the limiting ring and one end of the positioning post extends beyond the limiting ring.

The sides of the second slider and the fixing block that are close to each other are provided with inclined surfaces. A second spring is sleeved on the outer wall of the limiting rod, and the second spring is located between the sliding plate and the fixed plate. When the second slider and the fixing block are close to each other, the second slider pushes the sliding plate to contact all the positioning posts through the fixing block and pushes the positioning posts back to their original positions.

[0014] Preferably, the light source includes a fluorescent lamp mounted on the top of the housing and a condenser with an opening at the bottom, with the fluorescent lamp located inside the condenser.

[0015] Preferably, the medicine placement component includes a medicine tray, which is hinged to the end of the telescopic component via a ball joint. The medicine tray has a through-hole for placing reagent tubes, and a rubber limiting ring is provided on the inner wall of the through-hole.

Subsequent inspections only require quick adjustments based on the markings, eliminating the need for repeated trial and error. This reduces operational steps, saves time, avoids inconsistencies in inspection positions caused by differences in personnel operation, ensures uniform inspection standards for the same batch, and improves the accuracy and reliability of inspection results.

[0033] 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.

[0034] like Figure 1-11 As shown: Embodiment 1 of the present invention is as follows:

[0035] A device for detecting the clarity of injectable preparations includes a housing 1 with an opening on the front side, a light source 2 installed inside the housing 1, a lifting mechanism 3 installed on the side wall of the housing 1, a first slider 4 slidably mounted on the lifting mechanism 3, a telescopic component 5 installed on one side of the first slider 4, and a medicine placement component 6 for placing medicine bottles hinged to the telescopic end of the telescopic component 5. A telescopic drive mechanism 7 is installed on the top of the housing 1, and the telescopic drive mechanism 7 is connected to the telescopic component 5 and drives the telescopic component 5 to extend and retract. The lifting mechanism 3 and the telescopic drive mechanism 7 are respectively provided with a first marking component 8 and a second marking component 9 with identical structures. When the detector detects the first medicine bottle of the same batch of medicine bottles, it drives the medicine placement component 6 to slide to the optimal detection position through the lifting mechanism 3 and the telescopic drive mechanism 7, and then marks the height and horizontal position of the medicine placement component 6 through the first marking component 8 and the second marking component 9, respectively.

[0036] In this embodiment, the telescopic component 5 includes a first screw 51 rotatably connected to the first slider 4, a threaded sleeve 52 threadedly connected to the outer wall of the first screw 51, a medicine placement component 6 installed at one end of the threaded sleeve 52, and a limiting shaft that cooperates with the threaded sleeve 52 is provided on the side wall of the box body 1.

[0037] The telescopic drive mechanism 7 includes a first housing 71 mounted on the top of the housing 1. A telescopic rod 72 is rotatably connected to the top of the inner cavity of the first housing 71, and the telescopic end of the telescopic rod 72 is inserted into the first slider 4 and a first driving bevel gear 73 is installed thereon. A first driven bevel gear 74, which meshes with the first driving bevel gear 73, is fixedly connected to the end of a first screw 51. A second driven bevel gear 75 is fixedly connected to the outer wall of the fixed end of the telescopic rod 72. A second screw 76 is rotatably connected to the bottom of the inner cavity of the first housing 71. A second driving bevel gear 77, which meshes with the second driven bevel gear 75, is fixedly connected to the outer wall of one end of the second screw 76. A transverse drive component 78 is installed at the other end of the screw 76, and the transverse drive component 78 extends through the front side of the housing 1. The second marking component 9 is connected to the second screw 76. The telescopic component adopts a threaded engagement structure of the first screw and the threaded sleeve, which provides stable transmission and high precision, and can accurately adjust the horizontal position of the medicine placement component. The telescopic drive mechanism transmits the power of the transverse drive component to the first screw through the transmission of the telescopic rod, multiple sets of bevel gears and the second screw, realizing remote driving of the telescopic component. It is easy to operate and has good synchronization in the transmission process, ensuring the accuracy of the horizontal position adjustment and providing a basis for the accurate positioning of the second marking component.

[0038] In this embodiment, in order to quickly mark the detection position, the second marking component 9 includes a fixing plate 91. The fixing plate 91 is embedded in the front side of the first housing 71. A plurality of positioning posts 92 are slidably connected through the front side of the fixing plate 91 at equal intervals. An elastic limiting ring 93 is fixed to the outer wall of one end of the positioning post 92 that protrudes from the rear side of the fixing plate 91. A limiting ring 94 is provided on the rear side of the fixing plate 91, which corresponds to and cooperates with the positioning posts 92. The inner hole of the limiting ring 94 is adapted to the elastic limiting ring 93. A second screw 76 is threadedly connected to a second slider 95. An L-shaped connecting rod 96 is connected to the top of the second slider 95. One end of the L-shaped connecting rod 96 protrudes from the top of the first housing 71 and bends towards the front side of the first housing 71. The free end of the L-shaped connecting rod 96... The mounting block 97 is fixedly connected to the front side of the fixing plate 91. The mounting block 97 is slidably connected to the elastic squeezing column 98. After the medicine placement piece 6 moves laterally into place, the elastic squeezing column 98 is pressed. The elastic squeezing column 98 pushes the positioning column 92, so that the elastic limiting ring 93 is inserted into the limiting ring 94 and one end of the positioning column 92 protrudes from the limiting ring 94. The second marking component can form a physical mark at the optimal horizontal position through the cooperation of the positioning column, the elastic limiting ring and the limiting ring. The structure is simple and the marking is intuitive. The second screw drives the second slider and the L-shaped connecting rod to move, so that the elastic squeezing column is aligned with the corresponding positioning column. After pressing, the marking is completed. The operation is convenient and the marking position is accurate, which makes it easy to quickly adjust the medicine placement piece to the optimal position during subsequent testing.

[0039] In this embodiment, the elastic compression column 98 includes a compression column 981 slidably connected to the mounting block 97. A compression block 982 is provided at the end of the compression column 981 away from the positioning column 92. A connecting block 983 is fixedly connected to the outer wall of the compression column 981, and the connecting block 983 is located between the mounting block 97 and the positioning column 92. A first spring 984 is sleeved on the outer wall of the compression column 981. Both ends of the first spring 984 are connected to the connecting block 983 and the mounting block 97, respectively. The first spring 984 is in a compressed state when not compressed. Meanwhile, the ends of the positioning column 92 and the compression column 981 that are close to each other are both rounded. The first spring of the elastic compression column is initially in a compressed state, and when the compression block is pressed, the spring is stretched. The spring is constantly compressed and stored. After being released, it resets and automatically returns the extrusion column to its original position, eliminating the need for manual operation. The connecting block and the mounting block work together to limit the sliding range of the extrusion column, preventing damage to the positioning column and ensuring stable extrusion force to improve marking stability. Because the spring is always compressed, after the initial press creates a notch, when the elastic extrusion column slides back to the same position, the spring will push the extrusion column to automatically insert into the notch for precise positioning, making subsequent testing more convenient and ensuring consistent testing positions for the same batch. Furthermore, the rounded head design allows the extrusion column to slide smoothly out of the notch when its position needs to be adjusted after being inserted into the notch, thanks to the smooth transition between the rounded heads and the automatic sliding of the extrusion column.

[0040] In this embodiment, the cross-sectional shape of the inner hole of the limiting ring 94 is frustum-shaped, and the inner hole diameter of the limiting ring 94 at the end near the fixing plate 91 is larger than the inner hole diameter at the end away from the fixing plate 91. The inner hole of the limiting ring is set to frustum-shaped, and the diameter at the end near the fixing plate is larger, which facilitates the elastic limiting ring to smoothly enter the limiting ring during extrusion and reduces jamming. At the same time, the tapered diameter structure can form a radial constraint on the elastic limiting ring, preventing the positioning post from accidentally loosening after marking and ensuring the durability of the mark.

[0041] In this embodiment, in order to quickly clean the marking positions after a batch of medicine bottles has been inspected, the second marking assembly 9 also includes two limiting rods 99 located at opposite ends of the rear side of the fixed plate 91. A sliding plate 910 is slidably connected between the two limiting rods 99. A fixing block 911 that cooperates with the second slider 95 is installed on the side of the sliding plate 910 away from the fixed plate 91, and the fixing block 911 is located at one end of the sliding plate 910. The sides of the second slider 95 and the fixing block 911 that are close to each other are both provided with inclined surfaces. A second spring 912 is sleeved on the outer wall of the limiting rod 99. Located between the sliding plate 910 and the fixed plate 91, when the second slider 95 and the fixed block 911 approach each other, the second slider 95 pushes the sliding plate 910 to contact all the positioning posts 92 through the fixed block 911 and pushes the positioning posts 92 back to their original positions. By setting the sliding plate, the fixed block and the second spring, when the second slider moves in the opposite direction, the inclined surface can push the sliding plate to squeeze all the positioning posts, so that the elastic limit ring is disengaged from the limit ring, realizing the automatic reset of the positioning posts. There is no need to manually reset them one by one, which facilitates the quick switch to the next batch of testing after the same batch of testing is completed, improving the reusability and operating efficiency of the equipment.

[0042] In this embodiment, the lifting mechanism 3 includes a second housing 31 installed on the side wall of the housing 1 (the top of the second housing 31 is connected to the first housing 71 and forms a whole). A third screw 32 and a limiting post 33 are installed between the top and bottom of the inner cavity of the second housing 31. The first slider 4 is threadedly connected to the third screw 32 and the limiting post 33 respectively. A lifting drive component 34 is installed on the upper end of the third screw 32 and extends through the front side of the housing 1. A first marking component 8 is installed on the front side of the second housing 31 and connected to the first slider 4. The lifting mechanism adopts a cooperative structure of the third screw and the limiting post. The third screw has high transmission accuracy and can accurately adjust the height position of the first slider. The limiting post can prevent the first slider from rotating and ensure stable height adjustment. The lifting drive component is easy to operate manually, and the first marking component is linked with the first slider to synchronously mark the optimal height position. It cooperates with the second marking component to achieve full-dimensional positioning and improve the standardization of detection.

[0043] In this embodiment, the light source 2 includes a fluorescent lamp 21 installed on the top of the housing 1 and a condenser 22 with an opening at the bottom. The fluorescent lamp 21 is located inside the condenser 22. The light source uses a fluorescent lamp in conjunction with the condenser. The light intensity of the fluorescent lamp is stable and meets the requirements of the pharmacopoeia for the detection light source. The condenser can concentrate the light onto the detection area, improve the light utilization rate, ensure that the illuminance of the detection area is uniform and meets the standard, provide a stable lighting environment for clarity detection, and reduce detection errors caused by unstable lighting.

[0044] In this embodiment, the medicine placement component 6 includes a medicine tray 61, which is hinged to the end of the telescopic component 5 via a ball joint 62. The medicine tray 61 has a through-hole 63 for placing reagent tubes, and a rubber limiting ring 64 is provided on the inner wall of the placement hole 63. The medicine placement component is connected to the telescopic component via the ball joint, which allows for flexible adjustment of the angle of the medicine tray to meet the operational requirements of the "straight, horizontal, and inverted" three-step detection of the medicine bottle. The rubber limiting ring in the placement hole can not only fix the medicine bottle and prevent it from shaking during detection, but also prevent the medicine bottle from directly colliding with the placement hole and causing damage, thus improving the safety of the detection process.

[0045] In this embodiment, to enable quick adjustment to a suitable illuminance range during detection and positioning, followed by fine-tuning, a clearance groove 53 is provided at the end of the telescopic component 5. A rotating rod 54 is rotatably connected between the top and bottom of the clearance groove 53. A rotating shaft 55 is connected to the outer wall of the rotating rod 54. Ball joints 62 are connected to opposite ends of the rotating shaft 55. One ball joint 62 is hinged to a medicine tray 61, and the other ball joint 62 is hinged to a lux meter 65. The medicine tray and lux meter are connected by the rotating rod and rotating shaft, allowing for quick switching between the two components. Before detection, the lux meter is used to determine the required illuminance position, and then the rotation is switched to the medicine tray for reagent detection. No additional disassembly or installation of components is required, simplifying the operation process and improving detection efficiency. The clearance groove provides rotation space for the rotating rod, ensuring a smooth switching process.

[0046] In this embodiment, sliding grooves for the telescopic member 5 and the L-shaped connecting rod 96 to cooperate are respectively provided on the side walls of the box 1, the first shell 71 and the second shell 31. Two light-blocking curtains are provided on the sliding grooves on the side walls of the box 1, which are located on the upper and lower sides of the telescopic member 5 and connected to the telescopic member 5, so that the sliding grooves can be sealed when the telescopic member 5 is raised and lowered, thus preventing the light source from leaking out.

[0047] The specific working process of the above embodiments is as follows:

[0048] 1. Preparation before testing: Before testing the same batch of medicine bottles, first select the first medicine bottle as the calibration piece. At this time, it is necessary to operate the rotating shaft 55, which is installed in the relief groove 53 at the end of the telescopic component 5 (the relief groove 53 provides rotation space for the rotating shaft), and is rotatably connected to the threaded sleeve 52 through the rotating rod 54. Rotating the rotating shaft 55 can drive the ball joints 62 connected at both ends to rotate synchronously, thereby switching the illuminance meter 65 (connected to one of the ball joints) to the testing position, replacing the initial medicine tray 61 (connected to the other ball joint);

[0049] Next, position calibration is performed: rotate the lifting drive component 34, which includes a knob on the front side of the housing 1 and an internal gear set. The rotation of the knob drives the third screw 32 of the lifting mechanism 3 to rotate through the gear set. Since the first slider 4 is threadedly connected to the third screw 32 and is constrained by the parallel limit post 33 (the limit post 33 restricts the first slider 4 from rotating with the third screw 32), the first slider 4 slides smoothly in the vertical direction, thereby driving the telescopic component 5 and the illuminance meter 65 to adjust their height. Simultaneously, rotating the transverse drive component 78, which also includes a knob located on the front side of the housing 1 and an internal gear set, drives the second screw 76 of the telescopic drive mechanism 7 to rotate via the gear set. This, in turn, causes the telescopic rod 72 to rotate through the meshing of the second driving bevel gear 77 and the second driven bevel gear 75. The telescopic end of the telescopic rod 72 is inserted into the first slider 4, and its end, the first driving bevel gear 73, meshes with the first driven bevel gear 74 of the first screw 51, thereby driving the first screw 51 to rotate. This causes the threaded sleeve 52 to extend and retract horizontally, ultimately adjusting the illuminance meter 65 to a horizontal position. This adjustment is repeated until the illuminance meter 65 detects an illuminance value conforming to the pharmacopoeia specifications; this is the optimal detection position for this batch of medicine bottles.

[0050] 2. Position Marking: When the illuminance meter 65 reaches its optimal position in the horizontal direction, the rotation of the second screw 76 has driven the second slider 95 (threadedly connected to the second screw 76) to move to the corresponding position; the L-shaped connecting rod 96 connected to the top of the second slider moves accordingly, passing through the top of the first housing 71 and bending to the front side of the fixing plate 91 (the fixing plate is embedded in the front side of the first housing, belonging to the front operating area of ​​the equipment), driving the mounting block 97 at the end and the elastic pressing column 98 passing through it to align with the positioning column 92 at the current position (equidistantly arranged components embedded in the fixing plate, with the front end exposed on the front side) (if there is no pressing column and...). If the positioning column is not aligned, it can be adjusted by fine-tuning to ensure that the illuminance value is within the appropriate detection range. At this time, the operator presses the extrusion block 982 of the elastic extrusion column from the front side of the equipment, causing the extrusion column 981 to move towards the positioning column. The front end of the extrusion column pushes the positioning column 92 to slide backward, causing the elastic limiting ring 93 (made of rubber with elastic deformation capability) on the outer wall of the rear side of the positioning column 92 that is protruding from the fixed plate 91 to be compressed and deformed, and finally stuck into the limiting ring 94 (the limiting ring is fixed to the rear side of the fixed plate, and the inner hole is frustoconical, with a larger diameter at the end near the fixed plate to facilitate the entry and locking of the elastic limiting ring). As the positioning column 92 moves backward as a whole, the part of its front end that protrudes from the fixed plate from the front side forms a clear recessed notch, which is directly exposed on the front side of the equipment, becoming a clearly identifiable horizontal position mark.

[0051] Height position marking: When the illuminance meter 65 reaches the optimal position in the height direction, it is marked by the first marking component 8 (installed on the front side of the second housing 31 of the lifting mechanism). Its operation logic is the same as that of the second marking component 9, which is achieved by front side operation - that is, pushing the corresponding marking component from the front side of the housing 1 to form an identifiable notch on the front side, thereby recording the current height position of the first slider 4.

[0052] This process is repeated to mark the optimal points for each detection angle, and each point is marked individually, that is, the optimal detection points for the three detection angles of upright, horizontal, and inverted positions are marked respectively.

[0053] 3. Batch Testing: After marking, rotate the rotating shaft 55 again to switch the medicine tray 61 to the testing position via the ball joint 62. Place the medicine bottle to be tested into the placement hole 63 of the medicine tray. The rubber limiting ring 64 (which is elastic) on the inner wall of the hole will fit tightly against the outer wall of the medicine bottle to achieve stable fixation and prevent shaking during the testing process. Then, based on the markings, the positioning is quickly achieved: by rotating the knob of the horizontal drive component 78, the elastic extrusion column 98 moves with the mounting block 97 through the gear transmission and the linkage of components such as the second screw 76 and the second slider 95, until the first spring 984 in a compressed state pushes the extrusion column 981 to automatically insert into the marked notch formed by the positioning column 92, adjusting the medicine placement component 6 to the horizontal position marked by the second marking component 9. Then, by rotating the knob of the lifting drive component 34, the medicine placement component 6 is adjusted to the height position marked by the first marking component 8 through the gear transmission and the transmission of the third screw 32 and the first slider 4 (for example, when checking the upright direction of the medicine bottle, the horizontal and height positions of the medicine placement component 6 are slid to the previously marked points respectively), completing the positioning.

[0054] During testing, the angle of the medicine tray 61 is adjusted by utilizing the 360° rotation characteristic of the ball joint 62. That is, the upright direction of the medicine bottle is tested by rotating the medicine tray 61. Then, when adjusting the testing angle (adjusting to the horizontal or inverted angle), the horizontal and vertical positions of the medicine placement piece 6 are adjusted to the corresponding optimal points, and then the test is carried out to ensure that the clarity of the medicine is observed from different angles and meets the testing standards.

[0055] 4. Reset Operation: After the same batch of medicine bottles has been tested, a reset is required to prepare for the next batch of testing. Rotate the knob of the transverse drive component 78 in the reverse direction. This drives the second screw 76 to rotate in the opposite direction via the gear set, causing the second slider 95 to move towards the fixed block 911 (mounted at one end of the sliding plate 910) (set at the initial position at the end of the second screw 76, i.e., after the same batch of testing is completed). Since the sides of the second slider 95 and the fixed block 911 that are close to each other are both inclined surfaces, when they contact each other, the second slider pushes the fixed block through the inclined surface thrust, causing the sliding plate 910 to slide along the limiting rod 99 (fixed to both ends of the rear side of the fixed plate) towards the fixed plate, while simultaneously compressing the second spring 912 sleeved on the limiting rod 99 (initially in its natural state). During the movement of the sliding plate 910, its surface contacts the rear ends of all the positioning posts 92, pushing the positioning posts 92 forward and causing the elastic limit ring 93 to disengage from the constraint of the limit ring 94. This returns the positioning posts 92 to their initial positions (the rear ends of the positioning posts 92 are equipped with limit blocks to prevent the positioning posts 92 from falling off), thereby quickly eliminating the marks and completing the reset so that the next batch of inspections can be recalibrated and marked. When marking is performed subsequently, the second slider 95 slides and disengages from the contact with the fixed block 911, allowing the sliding plate 910 to return to its original position under the restoring force of the second spring 912, without affecting the marking of the next batch.
