Description

Technical Field

[0001] This application relates to the field of medical solution preparation technology, and proposes a solution preparation equipment for pre-treatment of medicine bottles. Background Technology In the field of medical solution preparation, with the continuous development of medical technology and the increasing demands of patients, the importance of solution preparation has become increasingly prominent. Precise, efficient, and safe solution preparation plays a crucial role in ensuring the treatment effect and medication safety for patients.

[0002] The drug preparation process involves the handling and mixing of various medications, with bottle pretreatment being a crucial step. Proper bottle pretreatment ensures accurate drug identification and dispensing, as well as smooth subsequent mixing operations, thereby improving the quality and efficiency of drug preparation. In traditional automated drug preparation systems, operators typically place the bottles to be prepared onto a tray, and then a robotic arm sequentially prepares the drugs from each tray. However, when there are certain steps involved in the preparation process (such as cutting or breaking bottles), this method becomes inefficient.

[0003] The aforementioned technologies suffer from the drawback of low efficiency in liquid preparation by robotic arms. Utility Model Content

[0004] In order to improve the efficiency of liquid preparation by robotic arms, this application provides a pretreatment device for medicine bottles in a liquid preparation system.

[0005] The liquid preparation equipment and medicine bottle pretreatment device provided in this application adopts the following technical solution: A pretreatment device for medicine bottles in a liquid preparation equipment includes: The medicine shelf has multiple trays for holding vials and ampoules. Each tray has a drug identification code for recording drug information on the tray. A first robotic arm is connected to the medicine rack. The first robotic arm is equipped with a gripping device and a detection camera. The detection camera is used to detect the drug identification code to detect the drug information on the tray and to feed back the drug information on the tray to the control module. A control module is connected to the first robotic arm, the gripping device, and the detection camera. The control module is used to control the first robotic arm and the gripping device to sequentially pick up the vial and the ampoule based on the drug information on the tray.

[0006] By adopting the above technical solution, after the detection camera identifies the drug information on the tray and feeds it back to the control module, the control module can control the first robotic arm to first perform the opening and placement of the vials, and then perform the cutting and placement of the ampoules. This ensures that when mixing the medication later, the vials are already opened, and only the ampoules need to be quickly opened and the medication drawn from the ampoules into the vials, thus improving the efficiency of medication preparation. The control module adaptively adjusts the motion logic of the first robotic arm according to the drug information on the tray, enabling the device to meet a variety of medication preparation needs and improving its applicability.

[0007] Optionally, the clamping device is provided with clamping claws, which are used to clamp the vial and the ampoule.

[0008] By adopting the above technical solutions, the clamping claws have a certain degree of versatility or adjustability, and can be compatible with ampoules and vials, thus enhancing the applicability of the equipment.

[0009] Optionally, the liquid preparation equipment bottle pretreatment device further includes a bottle-breaking device, which includes a bottle-breaking turntable and bottle-breaking grippers. The bottle-breaking grippers are used to hold the ampoule and drive the ampoule to tilt. The bottle-breaking turntable is used to engage with the ampoule to break it.

[0010] By adopting the above technical solution, the ampoule-breaking device automatically breaks the ampoules, avoiding the risks of glass cuts or contamination caused by manual operation and improving operational safety. Mechanical breaking speeds up ampoule processing and seamlessly integrates with the overall pre-treatment process, enhancing overall efficiency.

[0011] Optionally, the bottle-breaking device further includes multiple limiting posts, which are disposed on the bottle-breaking turntable. The limiting posts are used to engage with the cap of the ampoule, and the bottle-breaking turntable is used to drive the limiting posts to rotate so as to break the ampoule.

[0012] By adopting the above technical solution, the limiting post engages with the ampoule cap, providing a clear and stable point of force for the bottle-breaking turntable. This makes the engagement more precise and secure, further improving the success rate of the bottle-breaking action and the neatness of the break, and avoiding bottle-breaking failures caused by slippage or weak engagement.

[0013] Optionally, the bottle-breaking device further includes an ampoule recycling bin, which is located below the bottle-breaking turntable and is used to recycle the ampoule body and cap.

[0014] By adopting the above technical solution, the ampoule recycling bin is located below the ampoule-breaking turntable, allowing broken caps and processed ampoule bodies to fall directly into or be placed in the ampoule recycling bin. This achieves automatic collection of medical waste (broken glass), simplifies subsequent cleaning work, keeps the equipment clean, and avoids secondary risks caused by scattered broken glass.

[0015] Optionally, the liquid preparation equipment for pre-treatment of medicine bottles further includes a second robotic arm, which is equipped with a pull device and a needle tube. The second robotic arm is used to move the needle tube, and the pull device is used to pull the needle tube to transfer the medicine solution in the ampoule to the vial.

[0016] By adopting the above technical solution, using a syringe and a suction device, the volume of medication aspirated and injected can be controlled very precisely, ensuring the accuracy of the dosage. Using a syringe to transfer the medication minimizes the risk of contamination during the transfer process, meeting the aseptic requirements of medical procedures.

[0017] Optionally, the liquid preparation equipment bottle pretreatment device further includes a vial opening device. The vial opening device is equipped with an opening gripper and a vial cap recycling trough. The opening gripper is used to hold the vial cap, and the vial cap recycling trough is used to recycle the vial cap.

[0018] By adopting the above technical solution, the vial opening device can automatically complete the vial opening operation, thereby covering more front-end steps in the "ampoule-via" liquid preparation scenario, making the entire pretreatment process more complete and automated.

[0019] Optionally, the liquid preparation equipment bottle pretreatment device further includes an ampoule cutting device, which includes a cutting blade used to cut the pre-fractured part of the ampoule.

[0020] By employing the above technical solution, before breaking the ampoule, a cutting blade is used to slightly cut the pre-fracture point (usually the color ring or score line) of the ampoule neck, creating a stress concentration point. This allows the subsequent breaking action to result in a clean break at this point, with a smoother fracture and significantly reduced glass particle generation.

[0021] Optionally, the ampoule cutting device further includes a position sensor, which is used to detect the position information of the ampoule and feed the position information of the ampoule back to the first robotic arm. The first robotic arm is used to adjust the position of the ampoule according to the position information of the ampoule.

[0022] By adopting the above technical solution, the position sensor can detect the precise position of the ampoule in real time and feed the information back to the first robotic arm for fine-tuning. This ensures that the cutting blade always applies precisely to the pre-break point of the ampoule, greatly improving the reliability and accuracy of automated cutting.

[0023] Optionally, the liquid preparation equipment for pretreatment of medicine bottles further includes a shaking device. The shaking device is equipped with multiple shaking jaws for holding the vial. The shaking device is used to shake the vial to mix the liquid and powder in the vial.

[0024] By adopting the above technical solution, the shaking device not only replaces the tedious manual shaking, but also achieves standardized and repeatable shaking actions (speed, time and amplitude) through preset programs, ensuring that the drug dissolution is sufficient and consistent each time, and guaranteeing the uniformity of the final drug concentration and the stability of the drug efficacy.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. After the detection camera identifies the medication information on the tray and feeds it back to the control module, the control module can control the first robotic arm to first open and place the vials, and then cut and place the ampoules. This ensures that when mixing the medication, the vials are already open, and the ampoules only need to be quickly opened and the medication drawn from the ampoules into the vials, improving the efficiency of medication preparation. The control module adaptively adjusts the motion logic of the first robotic arm based on the medication information on the tray, enabling the device to meet various medication preparation needs and improving its applicability. 2. The ampoule-breaking device automatically breaks the ampoules, avoiding the risks of glass cuts or contamination associated with manual operation and improving operational safety. Mechanical breaking speeds up ampoule processing and seamlessly integrates with the overall pre-treatment process, enhancing overall efficiency. 3. The limiting post engages with the ampoule cap, providing a clear and stable point of force for the bottle-breaking turntable. This makes the engagement more precise and secure, further improving the success rate of the bottle-breaking action and the neatness of the break, and avoiding bottle-breaking failures due to slippage or weak engagement; 4. The position sensor can detect the precise position of the ampoule in real time and feed the information back to the first robotic arm for fine-tuning. This ensures that the cutting blade always applies precisely to the pre-break point of the ampoule, greatly improving the reliability and accuracy of automated cutting. Attached Figure Description

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0029] This application discloses a liquid preparation equipment and a medicine bottle pretreatment device.

Figure 2 This is a second-angle structural schematic diagram of a liquid preparation equipment bottle pretreatment device according to an embodiment of this application. Figure 3 This is a third-angle structural schematic diagram of a liquid preparation equipment bottle pretreatment device according to an embodiment of this application. Figure 4 yes Figure 3 An enlarged view of area A in the middle. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4The solution preparation equipment's vial pretreatment device includes a medicine rack 10, a platform 20, a first robotic arm 30, a second robotic arm 40, an ampoule cutting device 50, a bottle-breaking device 60, an vial opening device 70, a shaking device 80, and a control module. The medicine rack 10 is connected to the platform 20 and is used to hold vials 91 and ampoules 92. The first robotic arm 30, the second robotic arm 40, the ampoule cutting device 50, the bottle-breaking device 60, the vial opening device 70, and the shaking device 80 are all mounted on the platform 20. The first robotic arm 30 is used to remove vials 91 and ampoules 92 from the medicine rack 10 and move them. The second robotic arm 40 is used to transfer the solution from the ampoule 92 to the vial 91. The ampoule cutting device 50 is used to cut the pre-fracture point of the ampoule 92 to apply pre-stress. The bottle-breaking device 60 is used to break the ampoule 92. The vial-opening device 70 is used to open the cap of the vial 91. The shaking device 80 is used to shake the vial 91 to fully mix the liquid and powder inside. The control module is connected to the first robotic arm 30, the second robotic arm 40, the ampoule cutting device 50, the bottle-breaking device 60, the vial-opening device 70, and the shaking device 80. The control module is used to control the first robotic arm 30, the second robotic arm 40, the ampoule cutting device 50, the bottle-breaking device 60, the vial-opening device 70, and the shaking device 80 to complete the drug preparation process.

[0031] The medicine rack 10 is provided with multiple trays 11, which are used to place the vials 91 and the ampoules 92. The trays 11 are usually made of plastic or metal, and are generally square in shape. They have multiple grooves on their surface for placing the vials 91 and the ampoules 92.

[0032] The first robotic arm 30 is equipped with a gripping device 31, which has gripping jaws 32 and a detection camera 33. The tray 11 has a drug identification code 11a. The control module is connected to the first robotic arm 30, the gripping device 31, and the detection camera 33. The drug identification code 11a is used to record drug information on the tray 11. The detection camera 33 is used to detect the drug identification code 11a to read the drug information on the tray 11 and feed it back to the control module. The control module is used to control the first robotic arm 30 and the gripping device 31 according to the drug information on the tray 11 to sequentially grip the vial 91 and the ampoule 92. The clamping claws 32 are used to clamp the vial 91 and the ampoule 92. The clamping device 31 is equipped with a motor and a transmission mechanism. The motor drives the transmission mechanism to open or close the clamping claws 32. The clamping claws 32 are generally made of metal and have rubber pads and anti-slip textures on their inner sides, which can better clamp the vial 91 and the ampoule 92.

[0033] The vial opening device 70 includes an opening gripper 71 and a vial cap recycling groove 72. The opening gripper 71 is used to hold the cap of the vial 91, and the vial cap recycling groove 72 is used to recycle the cap of the vial 91. The opening gripper 71 is driven to open and close by a motor or cylinder, and its shape is designed according to the cap of the vial 91 to tightly grip the cap of the vial 91. When the first robotic arm 30 picks up the vial 91 from the medicine rack 10 and moves the vial 91 to the vial opening device 70, the opening gripper 71 holds the cap of the vial 91, and the first robotic arm 30 moves the vial 91 away from the opening gripper 71 to open the vial 91. When the vial 91 is opened, the first robotic arm 30 places the vial 91 onto the shaking device 80, and the cap-opening gripper 71 releases the cap of the vial 91, which then falls into the vial cap recycling trough 72.

[0034] The ampoule cutting device 50 includes a cutting blade 51 and a position sensor 52. The cutting blade 51 is used to cut the pre-fracture point of the ampoule 92 to apply pre-stress to the pre-fracture point. The cutting blade 51 is typically a circular grinding wheel made of cemented carbide, which is driven by a motor to rotate and perform the cutting operation. The position sensor 52 is used to detect the position information of the pre-fracture point of the ampoule 92 and feed it back to the first robotic arm 30. The first robotic arm 30 is used to adjust the position of the ampoule 92 according to the position information of the pre-fracture point. The position sensor 52 can be an infrared sensor or a laser sensor, which can accurately detect the position of the ampoule 92. When the first robotic arm 30 removes the ampoule 92 from the medicine rack 10 and moves the ampoule 92 to the ampoule cutting device 50, the cutting blade 51 cuts the pre-fracture point of the ampoule 92 to apply pre-stress.

[0035] The second robotic arm 40 is equipped with a pull-out device 41, on which a needle 42 is mounted. The second robotic arm 40 moves the needle 42, and the pull-out device 41 pulls the needle 42 to transfer the medication from the ampoule 92 to the vial 91. The pull-out device 41 has a screw and nut mechanism inside; a motor drives the screw to rotate, causing the nut to pull the needle 42. The needle 42 is generally made of glass or plastic, with a sharp and resilient tip. When the bottle-breaking device 60 breaks open the ampoule 92, the second robotic arm 40 moves the needle 42 to the ampoule 92, and the pull-out device 41 controls the needle 42 to draw the medication from the ampoule 92. Then, the second robotic arm 40 moves the needle 42 to the vial 91, and the pull-out device 41 controls the needle 42 to inject the medication into the vial 91.

[0036] The shaking device 80 includes multiple shaking grippers 81, which are used to hold the vial 91. The shaking device 80 is used to shake the vial 91 to mix the liquid and powder medicine inside. The shaking grippers 81 use springs or elastic materials to hold the vial 91, ensuring that the vial 91 will not fall during shaking. The shaking device 80 has an eccentric wheel structure inside, and a motor drives the eccentric wheel to rotate, causing the shaking grippers 81 to shake. When the first robotic arm 30 removes the vial 91 from the medicine rack 10 and moves the vial 91 to the shaking gripper 81, the shaking gripper 81 holds the vial. When the pull-out device 41 controls the syringe 42 to inject the medicine into the vial 91, the shaking device 80 shakes the vial 91 to fully mix the medicine and powder inside the vial 91.

[0037] Figure 5 This is a schematic diagram of the fourth angle of a liquid preparation equipment for pre-treatment of medicine bottles according to an embodiment of this application. Figure 6 yes Figure 5 A magnified view of area B in the middle section. (Refer to...) Figure 5 and Figure 6 The bottle-breaking device 60 includes a bottle-breaking turntable 61, multiple limiting posts 62, bottle-breaking grippers 63, and an ampoule recycling tank 64. The limiting posts 62 are disposed on the bottle-breaking turntable 61 and are used to engage with the caps of the ampoule 92. The bottle-breaking turntable 61 drives the limiting posts 62 to rotate, thereby breaking the ampoule 92. The bottle-breaking grippers 63 hold the ampoule 92, and the ampoule recycling tank 64 collects the caps and bodies of the ampoule 92. When the first robotic arm 30 moves the cut ampoule 92 to the bottle-breaking device 60 and places the ampoule 92 on the bottle-breaking gripper 63, the bottle-breaking gripper 63 clamps the ampoule 92 and tilts it so that the cap of the ampoule 92 engages with the limiting post 62. The bottle-breaking turntable 61 drives the limiting post 62 to rotate, breaking the ampoule 92. The cap of the ampoule 92 falls into the ampoule recycling tank 64. After the ampoule 92 is broken, the bottle-breaking gripper 63 tilts the ampoule 92 so that the opening of the ampoule 92 faces the second robotic arm 40. The second robotic arm 40 draws out the liquid medicine from the ampoule 92 and injects it into the vial 91. After the liquid medicine in the ampoule 92 is extracted, the ampoule clamp 63 releases the ampoule 92, and the ampoule 92 falls into the ampoule recycling tank 64.

[0038] The implementation principle of the pre-processing device for dispensing medicine vials in this application embodiment is as follows: After the detection camera 33 identifies the drug information on the tray 11 and feeds it back to the control module, the control module can control the first robotic arm 30 to first perform the opening and placement of the vial 91, and then perform the cutting and placement of the ampoule 92, based on the drug information on the tray 11. This ensures that when mixing the medicine later, the vial 91 is already opened, and only the ampoule 92 needs to be quickly opened and the medicine in the ampoule 92 needs to be drawn into the vial 91, thus improving the efficiency of dispensing. The control module adaptively adjusts the motion logic of the first robotic arm 30 according to the drug information on the tray 11, so that the device can meet a variety of dispensing needs and improve the applicability of the device.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
