Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pharmaceutical testing technology, specifically relating to a finished infusion testing device. Background Technology
[0002] Testing of finished infusion solutions is a crucial step in ensuring the safety of clinical medication. Its core objective is to ensure that the infusion meets standards in terms of effectiveness, safety, and stability through multi-dimensional quality control. This includes observing the color of the infusion solution to ensure it conforms to standards, checking for discoloration, fading, the presence of foreign matter such as fibers, glass shards, black spots, sediment, or turbidity. For emulsions and suspensions, particle size uniformity must be checked. Clarity is assessed using light inspection, such as with a canopy lamp or an automated light inspector, ensuring the solution is clear and free of visible foreign matter, except for permissible slight opalescence. Currently, the preparation of medications in infusion bags is increasingly automated, reducing the risks associated with manual processing. However, automated preparation can sometimes result in insufficient drug dissolution or high residual liquid levels in the vial, leading to substandard medication quality. Therefore, appropriate testing methods are necessary.
[0003] In existing technologies, automated drug testing equipment typically uses conveyor belts for continuous testing to accelerate efficiency. However, for vials, ampoules, and soft-bag drugs, debris can be generated during transport on the conveyor belt. For example, infusion bottles are often made of PP polypropylene, PE polyethylene, or glass. During conveying, sorting, and collisions on the production line, tiny debris may be generated due to friction and compression, such as plastic burrs on bottle caps or fine glass shards from glass bottles. Similarly, rubber stoppers and aluminum-plastic composite caps on vials may generate rubber fragments and aluminum foil particles during puncture leak testing or opening simulations. These debris can affect the drug testing results, leading to inaccurate test outcomes. Utility Model Content

The syringe operating mechanism 7 is used to fix the syringe barrel and push and pull the syringe plunger. A dust collection assembly 8 is installed on one side of the transmission line 2. The dust collection assembly 8 includes a track 81 and a dust collection plate 94. The dust collection plate 94 slides inside the track 81 to absorb debris above the transmission line 2.
[0036] Specifically, the tray 3 is first placed above the transmission line 2, and the vacuum plate 94 slides inside the track 81, thus passing over the tray 3. According to the shape of the track 81, the vacuum plate 94 will rise and fall during the movement, so that the vacuum plate 94 can get as close as possible to the vials or ampoules of medicine waiting to be tested placed on the tray 3 to achieve the vacuuming function.
[0037] It should be noted that the industrial camera 5 takes pictures of the infusion bag and transmits the pictures to the computer. The computer system uses AI technology to identify and analyze the pictures, and then detects the clarity of the liquid in the infusion bag, visible foreign objects, and insoluble particles.
[0038] Please see Figure 1 The transmission line 2 carries a tray 3 for carrying infusion bags and medicine bottles; a barcode scanner 4 is installed above the beginning of the transmission line 2 for scanning and identifying the labels on the infusion bags; multiple drive rollers 21 are installed inside the transmission line 2, and one of the drive rollers 21 is equipped with a second bevel gear 22 at one end.
[0039] Specifically, the barcode scanner 4 is used to scan the medicines in the first placement slot 31 and the second placement slot 32 to identify the labels on the medicines. The transmission roller 21 is driven by an external motor, which drives the transmission line 2 to rotate, thereby realizing the function of conveying medicines, so as to facilitate continuous detection and improve the detection speed.
[0040] Please see Figure 1 , Figure 2 and Figure 3The robotic arm 6 is used to grip the medicine bottle and deliver it to the syringe operating mechanism 7. The robotic arm 6 cooperates with the syringe operating mechanism 7 to enable the syringe operating mechanism 7 to operate the syringe to extract the residual liquid in the medicine bottle. The tray 3 is provided with a first placement slot 31 for holding the infusion bag and multiple second placement slots 32 for holding the medicine bottle. The syringe operating mechanism 7 includes a mounting frame 71, a positioning block 72, a fixing block 73, a moving arm 74, and an operating block 75.

The syringe is fixed; the front end of the operating block 75 is provided with a mounting groove for the push rod handle, which can limit the push rod along the length direction of the push rod; the lifting component 76 can adopt a screw slide rail transmission mechanism and be driven by a servo motor; it can enable the moving arm 74 to drive the operating block 75 to move stably and controllably; the lifting component 76 drives the moving arm 74 and the operating block 75 to move, thereby driving the push rod to push and pull relative to the syringe; when the robot arm 6 delivers the medicine bottle to the syringe operating mechanism 7, the syringe operating mechanism 7 can operate the syringe to draw liquid from the medicine bottle;
[0042] It should be noted that tray 3 carries the infusion bag and medicine bottle. Ampoules and vials are placed at the beginning of conveyor line 2. The barcode scanner 4 scans the label on the infusion bag to identify the relevant information of the medicine contained in the infusion bag. Then, conveyor line 2 moves tray 3 to industrial camera 5, so that the infusion bag is directly below industrial camera 5. Industrial camera 5 captures image information of the infusion bag, and the computer uses AI technology for identification and analysis. Conveyor line 2 continues to move tray 3 to the end. Robotic arm 6 uses grippers to grab the medicine bottle and transfers it to syringe operating mechanism 7. Robotic arm 6 and syringe operating mechanism 7 cooperate to draw liquid from the medicine bottle through syringe, and then put the medicine drawn from the syringe into a special detector for testing.
[0043] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 The dust collection assembly 8 includes a fixed box 80 installed on one side of the transmission line 2. A track 81 is provided on the outer wall of the fixed box 80. A fixing ring 86 is installed at the bottom of the fixed box 80. A rotating shaft 82 is installed on the inner wall of the fixing ring 86. A first bevel gear 83 is installed at one end of the rotating shaft 82, and the first bevel gear 83 meshes with a second bevel gear 22. A reciprocating screw assembly 84 is installed on the inner wall of the fixed box 80. A sprocket assembly 85 is installed on the outer wall of the screw of the reciprocating screw assembly 84, and the reciprocating screw assembly 84 and the rotating shaft 82 are connected by the sprocket assembly 85. A fixing frame 9 is installed on the outer wall of the slider of the reciprocating screw assembly 84. Two first slide rods 87 are installed through the outer wall of the fixed frame 9, and the two first slide rods 87 are respectively located above and below the lead screw of the reciprocating lead screw assembly 84 to limit the fixed frame 9. A second slide rod 91 is installed on the inner wall of the fixed frame 9. A lifting block 92 is slidably connected to the upper part of the second slide rod 91. A connecting rod 93 is installed through the outer wall of the lifting block 92, and the connecting rod 93 slides inside the track 81. A dust suction plate 94 is installed at one end of the connecting rod 93. Multiple dust suction pipes 95 are connected to the top of the dust suction plate 94. A vacuum cleaner 96 is installed on the inner bottom wall of the fixed box 80, and the dust suction pipes 95 and the vacuum cleaner 96 are connected through pipes.
[0044] Specifically, the medicine is first placed in the tray 3 of the conveyor line 2. Then, the transmission roller 21 rotates, driving the second bevel gear 22 to rotate. The second bevel gear 22 drives the first bevel gear 83 to rotate, thereby driving the rotating shaft 82 to rotate. The rotation of the rotating shaft 82 drives the screw in the reciprocating screw assembly 84 to rotate through the sprocket assembly 85. The slider of the reciprocating screw assembly 84 drives the fixed frame 9 to reciprocate. The two first sliding rods 87 can limit the fixed frame 9 to prevent it from rotating. The movement of the fixed frame 9 causes the connecting rod 93 and the dust suction plate 94 to slide inside the track 81. The lifting block 92 is on the second... The slide bar 91 slides up to adapt to changes in the route of the track 81. At the same time, the vacuum cleaner 96 works, sucking up dust and debris through the suction pipe 95. The bottom end of the suction pipe 95 extends to the bottom of the suction plate 94. The length of the suction plate 94 covers the length of the tray 3. So when medicines are placed in the first placement slot 31 and the second placement slot 32, the suction plate 94 can pass close to the top of the medicines. As the suction plate 94 passes over the tray 3, it sucks up debris, burrs and other impurities generated by the medicines in the tray 3, preventing these impurities from affecting the shooting of the industrial camera 5 and the accuracy of subsequent image recognition.
[0045] It should be noted that the dust extraction plate 94 can effectively reduce the dust content near the industrial camera 5, thereby effectively preventing dust from adhering to the lens of the industrial camera 5, ensuring the cleanliness of the lens, and improving the shooting effect.
