Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an integrated device for drug labeling, traceability scanning, and issuance. Background Art

[0002] With the development of technology, it is necessary to use big data to break through the information barriers in various links such as drug production, circulation, and use, promote the linkage between medical treatment and pharmacy, innovate drug supervision methods, and achieve precise tracking management of the entire drug life cycle. With the expansion of hospital scale and the need for traceability code management, the drug dispensing work in the outpatient pharmacy of hospitals has become increasingly heavy. At present, the overloaded working mode of hospital pharmacists for drug dispensing is becoming increasingly unsuitable for the operation scale of modern hospitals, resulting in more adverse events of incorrect drug issuance by pharmacists and an increase in the incidence of medical accidents. Under such overloaded checking and dispensing work, pharmacists are often prone to making mistakes in dispensing drugs due to fatigue, chaotic drug placement, especially the large number of drug labels, and it is difficult to carefully check the drugs for each patient. This not only fails to ensure the provision of accurate and quality-assured drugs to patients, but also cannot guarantee the safe and effective acceptance and use of drugs by patients.

[0003] Incorrect drug issuance may lead to patients not using the correct drugs on time, thus delaying the best treatment opportunity. Especially in the treatment of acute diseases or chronic diseases that require long-term control, delayed treatment may lead to further deterioration of the disease or the occurrence of complications, and even cause serious consequences. In addition, incorrect drug dispensing will lead to improper drug use by patients, easily aggravating the condition and causing adverse reactions, thereby damaging the hospital image and affecting the development of the hospital. Summary of the Invention

[0004] To solve the above problems, the present invention provides an integrated device for drug labeling, traceability scanning, and issuance, which is used to reduce the fatigue of users, the probability of drug labeling errors, improve the accuracy of drug issuance, and achieve closed-loop traceable management of the drug dispensing link.

[0005] To achieve the above object, the technical solution of the present invention is as follows: An integrated device for drug labeling, traceability scanning, and issuance, comprising,

[0006] A conveying component: used for conveying drugs;

[0007] A prescription scanner: used for scanning and identifying prescription forms;

[0008] A traceability code scanner: used for scanning the traceability code of drugs;

[0009] A drug packaging scanner: used for obtaining drug images on the conveying component;

[0010] A drug labeling component: used for printing labels and pasting the labels on the drugs on the conveying component;

[0011] Controller: The controller is used to obtain the drug images collected by the drug packaging scanner, and identify the labeling surface of the drug based on the packaging of the drug in the drug image through image recognition; when the labeling surface reaches directly below the drug labeling component, it controls the drug labeling component to paste the label on the drug; the controller is also used to obtain the traceability code obtained when the traceability code scanner scans the drug, and search for drug information in the preset information database and the preset hospital prescription system based on the traceability code. The drug information includes drug name, specification, dosage form, usage method, and drug expiration date; the controller is used to control the drug labeling component to print labels based on the drug information, and when the duration of the drug expiration date is lower than the preset value, an upcoming expiration warning label is additionally printed on the label.

[0012] The following beneficial effects can be obtained by adopting the above solution:

[0013] 1. In this solution, the drug taken out of the warehouse is placed on the conveying component, and during the placement process, the traceability code on the drug is scanned by the traceability code scanner, enabling the controller to search for drug information in the preset information database through the traceability code. The drug placed on the conveying component will be transported along the conveying component. During this process, the drug packaging scanner will collect the packaging image of the drug to identify the position of the labeling surface, thus preparing for the labeling work.

[0014] 2. In this solution, after scanning the traceability code, labels are made based on the retrieved drug information. When the drug moves directly below the drug labeling component, the controller will control the drug labeling component to label the drug, thus automatically completing the labeling operation, reducing the manual work intensity, and reducing the mistakes caused by the inattentiveness of the user.

[0015] 3. In this solution, the controller can identify the drug expiration date through the drug information. When the duration of the drug expiration date is lower than the preset value, an upcoming expiration warning label is additionally printed on the label to prompt the user and the patient to pay attention to the expiration date of the drug.

[0016] Furthermore, it also includes a frame, which is erected on the conveying component. The traceability code scanner is fixedly connected to the frame. The traceability code scanner is located on one side of the frame close to the entrance of the conveying component, and the scanning port of the traceability code scanner faces the conveying component.

[0017] Beneficial effect: The traceability code scanner is located on one side of the frame close to the entrance of the conveying component, which can facilitate the user to scan the traceability code when putting in the drug and has a more suitable position for putting the drug into the conveying component.

[0018] Furthermore, a drug receiving groove is provided on one side of the frame close to the exit of the conveying component, and the drug receiving groove is covered with a flexible layer.

[0019] Beneficial effect: The drug after labeling will fall into the drug receiving groove along with the conveying component, and the flexible layer in the drug receiving groove can buffer the impact force when the drug drops.

[0020] Furthermore, the rack is provided with a number of aligners. Each aligner includes a first telescopic rod, and the output shaft of the first telescopic rod is fixedly connected with a mechanical claw. The mechanical claw is used for clamping and rotating the medicine; the controller is used for controlling the aligner to correct the posture of the medicine according to the medicine image obtained by the medicine packaging scanner.

[0021] Beneficial effects: The posture of the medicine on the conveying assembly may be skewed, so the posture of the medicine needs to be corrected before labeling. The first telescopic rod can control the position of the mechanical claw, so that the position of the mechanical claw can adapt to medicines of different shapes. After the mechanical claw grabs the medicine by opening, it can drive the medicine to rotate, so that the medicine is in a posture suitable for labeling.

[0022] Furthermore, the number of aligners is 2, and they are respectively arranged longitudinally along the Z-axis and transversely along the X-axis of the conveying assembly. Among them, the aligner arranged transversely is fixedly connected with the rack, and the aligner arranged longitudinally is slidably connected with the rack through a chute. A driving member for driving the aligner to slide is provided in the chute.

[0023] Beneficial effects: The labeling surface of the medicine may face away from the medicine labeling assembly. Therefore, in addition to correcting the medicine, the medicine also needs to be flipped. The aligner arranged transversely along the X-axis can grab the medicine and flip it. In addition to the need for angle correction of the medicine, there may also be a position offset of the medicine. The chute can drive the aligner arranged longitudinally along the Z-axis to change its position, so as to adjust the position of the medicine.

[0024] Furthermore, a monitor is provided on the rack. The monitor is used for collecting real-time images of the medicine on the conveying assembly, label pasting images, and images of patients taking medicine from the medicine receiving groove.

[0025] Beneficial effects: The monitor can play a recording role, and record the real-time images of the medicine on the conveying assembly, label pasting images, and images of patients taking medicine from the medicine receiving groove respectively. When there is a problem with the medicine, the cause of the problem can be judged through the recorded images.

[0026] Furthermore, a display is fixedly connected to one side of the rack close to the medicine packaging scanner. The display is used for displaying medicine information.

[0027] Beneficial effects: The display can display the scanned medicine information. After the user scans the medicine, they can view the medicine information based on the traceability code.

[0028] Furthermore, a voice broadcasting device is provided on the frame, and a trained convolutional neural network is also provided in the controller. The convolutional neural network is trained based on prescription samples that are marked as to whether they are reasonable. The convolutional neural network is used to input a prescription and output whether the prescription is reasonable. The voice broadcasting device is used to broadcast an alarm voice when the drug expiration date is lower than a preset value, when the drug name and quantity do not match the prescription, or when the prescription is unreasonable.

[0029] Beneficial effects: The voice broadcast device can broadcast an alarm voice when the drug validity period is lower than the preset value, when the drug name and quantity do not match the prescription, or when the prescription is unreasonable, thereby reminding users and patients at the auditory level.

[0030] Furthermore, the medicine labeling assembly includes a second telescopic rod, on which a printing and labeling integrated machine is provided, and the controller is used to control the second telescopic rod to change the height of the printing and labeling integrated machine based on the packaging of the medicine.

[0031] Beneficial effect: The printing and labeling machine can automatically complete the printing and labeling operation, but the heights of different medicines are different. Therefore, the printing and labeling machine will control the operating height of the printing and labeling machine based on the packaging image of the medicine recognized by the controller to meet the labeling requirements.

[0032] Furthermore, a plurality of windows are provided on the frame, and guide brackets are provided at the label inlet and the label waste paper outlet of the printing and labeling all-in-one machine, and the guide brackets are extended out of the windows.

[0033] Beneficial effect: The label paper stored in the label printing and labeling machine is limited, and label waste paper will be generated after printing the label. The guide bracket extends out of the window, so that the user can complete the addition of label paper and the disposal of label waste paper outside the frame.

[0034] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following will be further described in detail through specific implementation manners:

[0044] As shown in the attached Figures 1 - 4 figures: A drug labeling, traceability, scanning, verification and integration device includes:

[0045] Conveyor assembly 1: Used to transport drugs, and the conveyor assembly 1 is a belt-type conveyor.

[0046] Prescription scanner 15: Used to scan and identify prescription forms.

[0047] Frame 5: The frame 5 is installed on the conveying component 1. The conveying component 1 enters from one side of the frame 5 and passes through to the other side. On one side of the frame 5 near the outlet of the conveying component 1, there is a medicine receiving groove 6, and a flexible layer covers the inside of the medicine receiving groove 6. The prescription scanner 15 is located on the frame 5.

[0048] Controller: Used for data processing and equipment control.

[0049] Traceability code scanner 2: Used to scan the traceability code of the medicine. The traceability code scanner 2 is a barcode scanning gun. The traceability code scanner 2 is bolted to the frame 5. The traceability code scanner 2 is located on one side of the frame 5 near the inlet of the conveying component 1, and the scanning port of the traceability code scanner 2 faces the conveying component 1.

[0050] Medicine packaging scanner 3: Used to obtain the image of the medicine on the conveying component 1. The medicine packaging scanner 3 is located on the frame 5, and the medicine packaging scanner 3 faces the conveying component 1.

[0051] Aligner: The number of aligners is 2, and they are respectively arranged longitudinally along the Z-axis and transversely along the X-axis of the conveying component 1. Among them, the transversely arranged aligner is bolted to the frame 5, and the longitudinally arranged aligner is slidably connected to the frame 5 through a chute 9. A driving member for driving the aligner to slide is provided in the chute 9, and the driving member is an electric lead screw. The aligner includes a first telescopic rod 7. The output shaft of the first telescopic rod 7 is fixed with a mechanical claw 8 by screws. The mechanical claw 8 has a rotating disk. The mechanical claw 8 is used to clamp the medicine and rotate the medicine; the controller is used to control the aligner to correct the posture of the medicine according to the medicine image obtained by the medicine packaging scanner 3.

[0052] Medicine labeling component: Used to print labels and paste the labels on the medicine on the conveying component 1. The medicine labeling component includes a second telescopic rod 12. A printing and labeling integrated machine 4 is provided on the second telescopic rod 12. The controller is used to control the second telescopic rod 12 to change the height of the printing and labeling integrated machine 4 based on the packaging of the medicine.

[0053] The controller is used to obtain the medicine image collected by the medicine packaging scanner 3, and identify the labeling surface of the medicine based on the packaging of the medicine in the medicine image through image recognition; when the labeling surface reaches directly below the medicine labeling component, control the medicine labeling component to paste the label on the medicine; the controller is also used to obtain the traceability code obtained when the traceability code scanner 2 scans the medicine, and search for medicine information in the preset information database and the preset hospital prescription system based on the traceability code. The medicine information includes medicine name, specification, dosage form, usage method, and medicine expiration date; the controller is used to control the medicine labeling component to print labels based on the medicine information, and when the duration of the medicine expiration date is lower than the preset value, additionally print a near-expiration warning label on the label; the controller is also used to proofread the scanned medicine name and quantity based on the prescription form.

[0054] It further includes a frame 5 which is mounted on the conveying assembly 1. The traceability code scanner 2 is fixedly connected to the frame 5. The traceability code scanner 2 is located on one side of the frame 5 close to the entrance of the conveying assembly 1, and the scanning port of the traceability code scanner 2 faces the conveying assembly 1.

[0055] On one side of the frame 5 close to the exit of the conveying assembly 1, there is a medicine receiving groove 6, and a flexible layer covers the inside of the medicine receiving groove 6.

[0056] The user stands on one side of the entrance of the conveying assembly 1 and places the medicine taken out from the warehouse on the conveying assembly 1. During the placement process, the traceability code on the medicine is scanned by the traceability code scanner 2, enabling the controller to search for medicine information in the preset information database through the traceability code. The medicine placed on the conveying assembly 1 will be transported along the transmission assembly. During this process, the medicine packaging scanner 3 will collect the packaging image of the medicine to identify the position of the labeling surface, thus preparing for the labeling work.

[0057] After identifying the position of the labeling surface, the controller will control the aligner to correct the position of the medicine. The actions that need to be corrected are to correct the lateral position of the medicine, flip the medicine so that the labeling surface faces up, and change the placement angle of the medicine to make the medicine straight.

[0058] The aligner arranged longitudinally along the Z-axis can clamp the medicine through the mechanical claw 8, thereby rotating the medicine, and complete the movement of the medicine through the driving part, completing the correction of the lateral position of the medicine and changing the placement angle of the medicine. And the mechanical claw 8 arranged horizontally along the X-axis can clamp the medicine and flip the medicine, so that the labeling surface faces up.

[0059] After scanning the traceability code, a label will be made based on the retrieved medicine information. When the medicine moves to directly below the medicine labeling assembly, the controller will control the medicine labeling assembly to label the medicine, thus automatically completing the labeling operation, reducing the manual work intensity, and reducing the mistakes caused by the user's inattention.

[0060] The controller can identify the expiration date of the medicine through the medicine information. When the expiration date duration of the medicine is lower than the preset value, a near-expiration warning mark will be additionally printed on the label to remind the user and the patient to pay attention to the expiration date of the medicine. The controller automatically proofreads the medicine information by means of informatization, realizes preventing misdispensing of medicine, near-expiration reminder, over-expiration interception, and inventory management, effectively improves the service management ability of the hospital pharmacy, and effectively avoids patients from buying fake drugs, returned drugs, and expired drugs.

[0061] The integrated printing and labeling machine 4 can automatically complete the printing and labeling operations. However, the heights of different drugs vary. Therefore, the integrated printing and labeling machine 4 will control the operating height of the integrated printing and labeling machine 4 based on the packaging images of the drugs recognized by the controller, so as to meet the labeling requirements. Using the integrated printing and labeling machine 4 can reduce the manual labeling and verification time, improve the overall work efficiency, reduce the drug labeling error rate, greatly reduce the incidence of drug adverse events, ensure the medication safety of patients, and is beneficial to the situation where users can work independently on duty.

[0062] After the labeling of the drugs is completed, the drugs will fall into the drug receiving slot 6 along with the conveying component 1. The flexible layer in the drug receiving slot 6 can buffer the impact force when the drugs fall. Subsequently, the patient takes the drugs from the drug receiving slot 6 to complete the drug dispensing process.

[0063] A monitor is provided on the frame 5. The monitor is used to collect the real-time images of the drugs on the conveying component 1, the label pasting images, and the images of the patient taking drugs from the drug receiving slot 6.

[0064] The monitor can play a recording role, recording the real-time images of the drugs on the conveying component 1, the label pasting images, and the images of the patient taking drugs from the drug receiving slot 6 respectively. When there are problems with the drugs, the cause of the problems can be judged through the recorded images.

[0065] A display 10 is bolted to one side of the frame 5 close to the drug packaging scanner 3. The display 10 is a touch screen display and is used to display drug information.

[0066] The display 10 can display the scanned drug information. After the user scans the drug, the user can view the drug information based on the traceability code. The user can operate or edit the information on the touch screen display to temporarily change the printing information.

[0067] A voice broadcast device 11 is bolted to the frame 5. There is also a trained convolutional neural network in the controller. The convolutional neural network is trained based on prescription samples with marked rationality. The convolutional neural network is used to input a prescription and output whether the prescription is reasonable. The voice broadcast device 11 is used to broadcast an alarm voice when the expiration period of the drug is lower than the preset value, when the number of drug names does not match the prescription, or when the prescription is unreasonable.

[0068] The voice broadcast device 11 can broadcast an alarm voice when the expiration period of the drug is lower than the preset value, so as to remind the user and the patient at the auditory level.

[0069] A number of windows 13 are opened on the frame 5. Guide brackets 14 are screwed and fixed at the label inlet and the label waste outlet of the integrated printing and labeling machine 4, and the guide brackets 14 all extend outside the windows 13.

[0070] The label paper stored in the integrated printer and labeler 4 is limited. At the same time, label waste paper will be generated after printing labels. The guiding bracket 14 extends outside the window 13, so that the user can add label paper and handle label waste paper outside the frame 5.

[0071] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
