Description

Technical Field

[0001] The present invention relates to the technical field of medicine bottle detection, in particular to a clarity detector. Background Art

[0002] In pharmaceutical production, clarity is a key quality indicator, and its test results are directly related to the safety and efficacy of the drug. Furthermore, according to pharmacopoeia regulations and standard operating procedures, different types of injectable preparations require different illumination ranges, and different specifications of injectable preparations require different sampling quantities per batch. To use the instrument, power on the power cord and turn on the fluorescent light. Use the mobile illuminometer and the illuminance display to determine the location that meets the required illumination requirements. Then, gently shake the bottle and place it in the corresponding position on the clarity tester for visual inspection. During the inspection, the bottle must be inspected in three steps: vertical, horizontal, and upside down.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] like Figure 1-11 As shown: Embodiment 1 of the present invention is: A device for detecting the clarity of an injection preparation comprises a box body 1 with an opening on the front side, a light source 2 installed inside the box body 1, a lifting mechanism 3 installed on the side wall of the box body 1, a first slider 4 slidably installed on the lifting mechanism 3, a telescopic member 5 installed on one side of the first slider 4, the telescopic end of the telescopic member 5 is hinged with a medicine placement member 6 for placing medicine bottles, a telescopic drive mechanism 7 is installed on the top of the box body 1, the telescopic drive mechanism 7 is connected to the telescopic member 5 and drives the telescopic member 5 to extend and retract, and a first marking component 8 and a second marking component 9 of the same structure are respectively provided on the lifting mechanism 3 and the telescopic drive mechanism 7. When the detector detects the first medicine bottle of the same batch of medicine bottles, the medicine placement member 6 is driven to slide to the optimal detection position by the lifting mechanism 3 and the telescopic drive mechanism 7 respectively, and the height position and horizontal position of the medicine placement member 6 are respectively marked by the first marking component 8 and the second marking component 9.

[0021] In this embodiment, the telescopic member 5 includes a first screw 51 rotatably connected to the first slider 4, the outer wall of the first screw 51 is threadedly connected to a threaded sleeve 52, one end of the threaded sleeve 52 is mounted with a medicine placement member 6, and the side wall of the box body 1 is provided with a limit shaft that cooperates with the threaded sleeve 52; The telescopic drive mechanism 7 includes a first shell 71 mounted on the top of the box body 1, a telescopic rod 72 is rotatably connected to the top of the inner cavity of the first shell 71, and the telescopic end of the telescopic rod 72 is inserted into the first slider 4 and is installed with a first active bevel gear 73, the end of the first screw 51 is fixedly connected to a first driven bevel gear 74 meshing with the first active bevel gear 73, the outer wall of the fixed end of the telescopic rod 72 is fixedly connected to a second driven bevel gear 75, the bottom of the inner cavity of the first shell 71 is rotatably connected, and the outer wall of one end of the second screw 76 is fixedly connected to a second active bevel gear 77 meshing with the second driven bevel gear 75, and the second A transverse drive member 78 is installed at the other end of the screw 76, and the transverse drive member 78 passes through the front side of the box body 1. The second marking component 9 is connected to the second screw 76. The telescopic member adopts a threaded matching structure of the first screw and the threaded sleeve. The transmission is stable and high-precision, and the horizontal position of the medicine placement member can be accurately adjusted; the telescopic drive mechanism transmits the power of the transverse drive member to the first screw through the telescopic rod, multiple sets of bevel gears and the second screw, realizing remote driving of the telescopic member. The operation is convenient, and the transmission process has good synchronization, ensuring the accuracy of the horizontal position adjustment, and providing a basis for the accurate positioning of the second marking component.

[0022] In this embodiment, in order to be able to quickly mark the detection position, the second marking component 9 includes a fixing plate 91, which is embedded in the front side of the first shell 71, and a number of positioning columns 92 are equidistantly penetrated and slidably connected to the front side of the fixing plate 91. The outer wall of one end of the positioning column 92 passing through the rear side of the fixing plate 91 is fixed with an elastic limiting ring 93, and the rear side of the fixing plate 91 is provided with a limiting ring 94 that corresponds to the positioning column 92 one by one, and the inner hole of the limiting ring 94 is adapted to the elastic limiting ring 93, the second screw 76 is threadedly connected to the second slider 95, and the top of the second slider 95 is connected to an L-shaped connecting rod 96, and one end of the L-shaped connecting rod 96 passes through the top of the first shell 71 and bends toward the front side of the first shell 71, and the free end of the L-shaped connecting rod 96 The part is fixed with a mounting block 97, and the mounting block 97 is located on the front side of the fixed plate 91. The mounting block 97 is slidably connected with an elastic extrusion column 98. After the medicine placement piece 6 is moved horizontally into place, the elastic extrusion column 98 is pressed, and the elastic extrusion column 98 pushes the positioning column 92, so that the elastic limiting ring 93 is stuck in the limiting ring 94 and one end of the positioning column 92 passes through 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 slider and the L-shaped connecting rod are driven by the second screw to move, so that the elastic extrusion column is aligned with the corresponding positioning column. The marking can be completed by pressing. It is easy to operate and the marking position is accurate, which is convenient for quickly adjusting the medicine placement piece to the optimal position during subsequent inspection.

[0023] In this embodiment, the elastic extrusion column 98 includes an extrusion column 981 that is slidably connected to the mounting block 97. An extrusion block 982 is provided at one end of the extrusion column 981 away from the positioning column 92. A connecting block 983 is fixed to the outer wall of the extrusion 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 extrusion column 981. The two ends of the first spring 984 are respectively connected to the connecting block 983 and the mounting block 97, and the first spring 984 is in a compressed state when not extruded. At the same time, the ends of the positioning column 92 and the extrusion column 981 that are close to each other are both set to round heads. The first spring of the elastic extrusion column is initially in a compressed state. When the extrusion block is pressed, the spring is pulled The extension deformation accumulates force, and the reset after release drives the extrusion column to return to its original position automatically without manual operation. The connecting block and the mounting block cooperate to limit the sliding range of the extrusion column, avoid damage to the positioning column and ensure stable extrusion force to improve marking stability. Moreover, because the spring is always compressed, after the first press forms a notch, when the elastic extrusion column slides to this position again, the spring will push the extrusion column to automatically insert into the notch to achieve precise positioning, making subsequent inspections more convenient and ensuring consistent inspection positions for the same batch. Moreover, the setting of the round head enables the extrusion column to be inserted into the notch. When the position of the extrusion column needs to be adjusted, the smooth transition between the round heads and the automatic sliding of the extrusion column can be used to make the extrusion column slide out smoothly from the notch.

[0024] In this embodiment, the cross-sectional shape of the inner hole of the limiting ring 94 is a truncated cone, and the inner hole diameter of the limiting ring 94 close to the fixed plate 91 is larger than the inner hole diameter of the end away from the fixed plate 91. The inner hole of the limiting ring is set to be truncated cone-shaped, and the diameter close to the fixed plate is larger, which facilitates the elastic limiting ring to smoothly enter the limiting ring during extrusion and reduce the jamming phenomenon; at the same time, the gradually shrinking diameter structure can form a radial constraint on the elastic limiting ring, prevent the positioning column from accidentally loosening after marking, and ensure the durability of the mark.

[0025] In this embodiment, in order to quickly clean the marking position after a batch of medicine bottles are 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, and 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 side of the second slider 95 and the fixing block 911 that are close to each other are both provided with an inclined surface, and the outer wall of the limiting rod 99 is provided with a second spring 912, and the second spring 9 12 is 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 through the fixed block 911 to contact all the positioning posts 92 and push 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 be used to push the sliding plate to squeeze all the positioning posts, so that the elastic limit ring is separated from the limit ring, thereby realizing automatic reset of the positioning posts. There is no need to manually reset them one by one, which is convenient for quickly switching to the next batch of testing after the same batch of testing is completed, thereby improving the reusability and operating efficiency of the equipment.

[0026] In this embodiment, the lifting mechanism 3 includes a second shell 31 installed on the side wall of the box body 1 (the top of the second shell 31 is connected to the first shell 71 and forms a whole), and a third screw 32 and a limit column 33 are installed between the top and bottom of the inner cavity of the second shell 31. The first slider 4 is threadedly connected and slidably connected to the third screw 32 and the limit column 33 respectively. A lifting drive member 34 is installed on the upper end of the third screw 32, and the lifting drive member 34 passes through the front side of the box body 1. The first marking component 8 is installed on the front side of the second shell 31 and is connected to the first slider 4. The lifting mechanism adopts a matching structure of the third screw and the limit column. The third screw has high transmission accuracy and can accurately adjust the height position of the first slider. The limit column can prevent the first slider from rotating, ensuring stable height adjustment; the lifting drive member is easy to operate manually, and the first marking component is linked with the first slider to synchronously mark the optimal height position, and cooperate with the second marking component to achieve full-dimensional positioning, thereby improving the degree of detection standardization.

[0027] In this embodiment, the light source 2 includes a fluorescent lamp 21 installed on the top of the box 1 and a spotlight 22 with an opening at the bottom, and the fluorescent lamp 21 is located inside the spotlight 22. The light source adopts a fluorescent lamp combined with a spotlight. The light intensity of the fluorescent lamp is stable and meets the requirements of the pharmacopoeia for the detection light source; the spotlight can concentrate the light to the detection area, improve the utilization rate of light, ensure that the illumination of the detection area is uniform and meets the standard, provide a stable lighting environment for clarity detection, and reduce the detection error caused by unstable light.

[0028] In this embodiment, the medicine placement piece 6 includes a medicine tray 61, which is hinged to the end of the telescopic piece 5 through a ball hinge 62. The medicine tray 61 is penetrated by a placement hole 63 for placing the reagent tube, and the inner wall of the placement hole 63 is provided with a rubber limiting ring 64. The medicine placement piece is connected to the telescopic piece through the ball hinge, and the angle of the medicine tray can be flexibly adjusted to meet the operational requirements of the "vertical, 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 to prevent shaking during detection, but also avoid direct collision between the medicine bottle and the placement hole to cause damage, thereby improving the safety of the detection process.

[0029] In this embodiment, in order to enable rapid adjustment to the appropriate illumination range before fine-tuning during detection and positioning, a clearance groove 53 is provided at the end of the telescopic member 5, and a rotating rod 54 is rotatably connected between the top and bottom of the clearance groove 53. The outer wall of the rotating rod 54 is connected to a rotating shaft 55, and the opposite ends of the rotating shaft 55 are respectively connected to ball hinges 62, one ball hinge 62 is hinged to a medicine tray 61, and the other ball hinge 62 is hinged to an illuminometer 65. The medicine tray and the illuminometer are connected by the rotating rod and the rotating shaft, and the two components can be quickly switched, that is, before detection, the illuminance position that meets the requirements is first determined by the illuminometer, and then the medicine tray is rotated to perform drug detection. There is no need to disassemble or install additional components, which simplifies the operation process and improves detection efficiency; the clearance groove provides rotation space for the rotating rod to ensure a smooth switching process.

[0030] In this embodiment, sliding grooves for cooperating with the telescopic part 5 and the L-shaped connecting rod 96 are respectively opened on the side walls of the box body 1, the first shell body 71 and the second shell body 31, and two light-blocking curtains are provided on the sliding groove of the side wall of the box body 1, which are respectively located on the upper and lower sides of the telescopic part 5 and connected to the telescopic part 5, so that the sliding groove can be sealed when the telescopic part 5 is raised or lowered to prevent the light source from leaking.

[0031] The specific working process of the above embodiment is as follows: 1. Pre-test preparation: Before testing medicine bottles from the same batch, first select the first medicine bottle as the calibration object. This requires operating the rotating shaft 55, which is installed in the clearance groove 53 at the end of the telescopic member 5 (the clearance groove 53 provides rotation space for the rotating shaft) and is rotatably connected to the threaded sleeve 52 via the rotating rod 54. Rotating the rotating shaft 55 drives the ball hinges 62 connected to its ends to rotate synchronously, thereby switching the illuminometer 65 (connected to one of the ball hinges) to the testing position, replacing the initial medicine tray 61 (connected to the other ball hinge); Next, position calibration is performed: the lifting drive member 34 is rotated, which includes a knob arranged on the front side of the box body 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 limit column 33 arranged in parallel (the limit column 33 limits 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 member 5 and the illuminance meter 65 to adjust the height. At the same time, the horizontal drive member 78 is rotated, which also includes a knob set on the front side of the box body 1 and an internal gear set. The rotation of the knob drives the second screw 76 of the telescopic drive mechanism 7 through the gear set. The second driving bevel gear 77 engages with the second driven bevel gear 75, driving the telescopic rod 72 to rotate. The telescopic end of the telescopic rod 72 is inserted into the first slider 4, and the first driving bevel gear 73 at its end engages with the first driven bevel gear 74 of the first screw 51, thereby driving the first screw 51 to rotate, causing the threaded sleeve 52 to extend and retract horizontally, ultimately driving the illuminometer 65 to adjust its horizontal position. Repeated adjustments are made until the illuminometer 65 detects an illumination value that meets the requirements of the pharmacopoeia. This is the optimal detection position for the batch of medicine bottles.

[0032] 2. Position marking: When the illuminometer 65 reaches the 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, passes through the top of the first shell 71 and bends to the front side of the fixing plate 91 (the fixing plate is embedded in the front side of the first shell and belongs to the front operation area of ​​the equipment), driving the mounting block 97 at the end and the elastic extrusion column 98 passing through it to align with the positioning column 92 (an equidistantly arranged component embedded in the fixing plate, with the front end exposed to the front side) at the current position (if there is no extrusion column and If the positioning column is not aligned, it can be adjusted through fine-tuning to ensure that the illumination 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 device, driving the extrusion column 981 to move toward the positioning column; the front end of the extrusion column pushes the positioning column 92 to slide backward, causing the elastic limiting ring 93 (such as rubber material, with elastic deformation ability) on the outer wall of one end of the rear side of the fixed plate 91 to be squeezed and deformed, and finally stuck in the limiting ring 94 (the limiting ring is fixed to the rear side of the fixed plate, and the inner hole is frustum-shaped, with a larger diameter near the end of the fixed plate to facilitate the entry and clamping of the elastic limiting ring). Because the positioning column 92 moves backward as a whole, the part of its front end that passes through the fixed plate from the front side forms a significantly concave notch, which is directly exposed to the front side of the device and becomes a clearly recognizable horizontal position mark.

[0033] Height Marking: When the illuminometer 65 reaches the optimal height position, it is marked by the first marking assembly 8 (mounted on the front side of the second housing 31 of the lifting mechanism). Its operating logic is the same as that of the second marking assembly 9, both operating from the front side. Specifically, the corresponding marking component is pushed from the front side of the housing 1, creating a recognizable notch on the front side. This notch then records the current height position of the first slider 4.

[0034] Repeat this process to mark the best point for each detection angle, and mark them one by one, that is, mark the best detection points for the three detection angles of upright, horizontal, and inverted respectively.

[0035] 3. Batch Testing: After marking is complete, rotate shaft 55 again, switching medicine tray 61 to the testing position via ball joint 62. Place the medicine bottle to be tested into placement hole 63 on the medicine tray. The elastic rubber retaining ring 64 on the inner wall of the hole will fit tightly against the outer wall of the medicine bottle, firmly securing it and preventing it from shaking during testing. Then, quickly position it according to the mark: turn the knob of the horizontal drive member 78, and through the gear group transmission and the linkage of the second screw 76, the second slider 95 and other components, make the elastic extrusion column 98 move with the mounting block 97 until the compressed first spring 984 pushes the extrusion column 981 to automatically insert into the marking gap formed by the positioning column 92, and adjust the medicine placement member 6 to the horizontal position marked by the second marking component 9, and then turn the knob of the lifting drive member 34, and through the gear group transmission and the transmission of the third screw 32 and the first slider 4, adjust the medicine placement member 6 to the height position marked by the first marking component 8 (for example, when detecting the upright direction of the medicine bottle, the horizontal position and height position of the medicine placement member 6 are respectively slid to the previously corresponding marked points), completing the position positioning. During testing, the 360° rotation characteristic of the ball hinge 62 is used to adjust the angle of the medicine tray 61, that is, the upright direction of the medicine bottle is detected by rotating the medicine tray 61. Then, when adjusting the detection angle (adjusting to a horizontal or inverted angle), the horizontal position and height position of the medicine placement part 6 are adjusted to the corresponding optimal point, and then the test is carried out to ensure that the clarity of the medicine is observed from different angles and meets the test standards.

[0036] 4. Reset Operation: After the inspection of the same batch of medicine bottles is completed, a reset is required to prepare for the next batch of inspections. Reversely rotate the knob of the transverse drive member 78, which drives the second screw 76 in the opposite direction through the gear train, causing the second slider 95 to move toward the fixed block 911 (mounted on one end of the sliding plate 910) (set at the starting position at the end of the second screw 76, i.e., slide to the starting position at the end of the second screw 76 after the inspection of the same batch is completed). Because the side of the second slider 95 that is close to the fixed block 911 is both inclined, when the two come into contact, the second slider pushes the fixed block through the thrust of the inclined surface, causing the sliding plate 910 to slide along the limit rod 99 (fixed at both ends of the rear side of the fixed plate) toward the fixed plate, while compressing the second spring 912 (initially in a natural state) mounted on the limit rod 99. During the movement of the sliding plate 910, its surface will contact the rear ends of all the positioning posts 92, pushing the positioning posts 92 to slide forward, so that the elastic limit ring 93 is freed from the constraint of the limit ring 94. The positioning posts 92 are returned to their initial positions (a limit block is provided at the rear end of the positioning posts 92 to prevent the positioning posts 92 from falling off), thereby quickly eliminating the mark and completing the reset so that recalibration and marking can be carried out during the next batch of inspections. During subsequent marking, the second slider 95 slides and disengages from the fixed block 911, so that the sliding plate 910 returns to its original position under the action of the restoring force of the second spring 912, without affecting the marking of the next batch.
