Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and relates to traceability code scanning in the management of medicines and consumables, and particularly to a roller-type drug and consumable traceability code scanning device for scanning traceability codes on the packaging boxes of medicines / consumables. Background Technology
[0002] Drug and medical consumable management is a crucial aspect of routine hospital management, involving the storage and use tracking of drugs across multiple stages, including drug warehousing, dispensing, and distribution. Drug management typically involves obtaining barcodes from drug packaging, scanning them to identify drug information, and then linking and storing this information with patient data for future traceability. Furthermore, similar to drug management, hospital consumables also require traceability management. Therefore, it is necessary to develop a traceability scanning device applicable to both drugs and consumables.
[0003] In existing technologies, firstly, there is a lack of relevant technologies for scanning consumable traceability, as this is a newly added aspect of consumable traceability management. Secondly, in drug traceability management, most methods involve manual scanning of barcodes on drug boxes using handheld barcode scanners. Drug information is typically obtained manually and then confirmed on a computer. However, existing technologies for traceability management of drug packaging usually require manual scanning, failing to achieve automatic scanning and recording. Furthermore, medication information is not linked to drug storage devices or patient information, resulting in low drug management efficiency.
[0004] Patent application number 202510166729.4 discloses an intelligent medicine cabinet and a refined management and control system for medicines. When storing medicines, the system first scans the barcode (or QR code) on the medicine for storage. During this scanning process, the barcode is aligned with the camera on the second display screen to partition the medicine cabinet, and then the medicine is placed into its corresponding storage compartment. When medicine needs to be retrieved, medical staff use a mobile scanner to scan the barcode generated on the first display screen on the cabinet door. The first scan information is received and recorded by the central control box. A second scan is then performed on the barcode generated on the second display screen on the cabinet. When retrieving the medicine, the barcode (or QR code) on the medicine is scanned again, and the scan information is recorded by the central control box, indicating that a specific medicine in a particular cabinet has left the hospital's medicine warehouse.
[0005] Current technologies, such as using handheld scanners to acquire and scan barcodes on drug packaging, or using cameras inside cabinets to capture images of drug packaging and identify barcodes within those images, can provide drug information for subsequent data linking and traceability. However, using handheld scanners increases the workload for staff. Installing cameras inside cabinets or frames to capture images of drug packaging and then using image recognition to extract barcode information is a better approach and represents the future trend of technological development.
[0006] In existing technologies, when using cameras to acquire images of drug packaging, the posture of the drugs within a cabinet or frame varies after placement, but the cameras are typically fixed. Therefore, the camera can only capture barcode information from drug boxes in partial postures (with the barcode facing the camera). For drugs in other postures, the camera struggles to capture a valid barcode on the packaging; either the image lacks a barcode, or the barcode is incomplete, making it impossible to effectively obtain drug information during subsequent identification. Of course, if this technology is applied to the traceability scanning management of consumables, the aforementioned problems will still exist.
[0007] Therefore, it is necessary to provide a traceability scanning device that can more effectively identify barcodes on the packaging boxes of medicines and consumables. Utility Model Content
[0008] The purpose of this invention is to address the technical problem in the prior art where cameras have difficulty capturing valid barcodes in images of drug / consumable packaging, thus affecting the identification and association of drug / consumable information. This invention provides a roller-type drug and consumable traceability code scanning device that adjusts the orientation of drug and consumable packaging boxes through its internal structure, allowing the barcodes on the packaging boxes to be captured by the camera in a better orientation, thereby improving the accuracy of drug and consumable information identification and association.
[0009] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0010] A roller-type drug and consumable traceability code scanning device includes a cylinder, a chassis at the bottom of the cylinder, multiple lateral cones arranged circumferentially on the inner side of the lower part of the cylinder, and multiple cameras arranged circumferentially on the inner side of the upper part of the cylinder; a central cone that can rotate relative to the chassis is provided on the chassis, and multiple push strips close to the chassis are arranged circumferentially on the central cone.
[0011] Furthermore, a passage gap is left between the bottom of the lateral cone and the top surface of the chassis, and the free end of the pusher bar is close to the inner side of the cylinder.
[0012] When the push rod rotates relative to the chassis along with the central cone, the free end of the push rod can pass through the gap.
[0013] Furthermore, the push bar includes an L-shaped connector fixedly connected to the central cone, and the end of the L-shaped connector is provided with spokes close to the chassis.
[0014] Furthermore, the spokes are arc-shaped.
[0015] Furthermore, the spokes have a triangular cross-section, and the bottom surface of the spokes is parallel and close to the chassis.
[0016] Furthermore, multiple concave and convex structures are provided at the top edge of the spokes.
[0017] Furthermore, the concave-convex structure includes raised structures, recessed structures, and planar structures, with multiple raised structures, recessed structures, and planar structures distributed along the length direction of the spokes.
[0018] Furthermore, the chassis is an inclined or conical surface; and as the spokes rotate with the central cone, they sweep across the top surface of the chassis close to it.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, the chassis and the central cone can rotate relative to each other (chassis or central turntable). The box body can be pushed outward by the push bar on the chassis and slide towards the lateral cone, so that the box body partially or completely slides onto the lateral cone, thereby adjusting the posture of the (medicine or consumable) box body so that its barcode can be fully exposed. This makes it easier for a camera on the top of the inner wall of the cylinder to capture the complete barcode. By recognizing the barcode, the drug information corresponding to the drug packaging box and the consumable information corresponding to the consumable packaging box can be obtained and used for subsequent information association. This improves the efficiency and accuracy of the collection of traceability codes for drugs and consumables, improves the accuracy of subsequent related information association, enables effective traceability of drugs and consumables, and improves the effectiveness of drug and consumable management.
[0021] 2. In this utility model, the spokes are set to be arc-shaped. The rotating arc-shaped spokes can push the box to rotate on the chassis while sliding outwards. During the movement of the box, it can slide onto the lateral cone more smoothly, making it easier to adjust the posture of the box on the lateral cone and making it easier to fully expose the barcode on the box to the camera's shooting range.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0032] Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0033] Example 1
[0034] This embodiment provides a roller-type drug and consumable traceability code scanning device, which is used to more efficiently and accurately obtain barcode information on the boxes of drugs and consumables, facilitating subsequent traceability. The term "roller-type" here refers to a device where the cylinder body is active, the spoke assembly is active, or both are active with opposite rotation directions. The purpose is to better enable the box 4 of drugs and consumables to move and rotate within the cylinder body 1, adjusting the posture of the box 4.
[0035] The scanning device includes a cylindrical body 1 with an open top and a base 5 at the bottom. The base 5 can be fixedly installed at the bottom of the body 1 or rotatably installed at the bottom of the body 1; in this embodiment, the base 5 is set to be non-rotatable, that is, the base 5 is fixedly installed at the bottom of the body 1.
[0036] Multiple lateral cones 6 are arranged on the lower inner side of the cylinder 1, above the chassis 5. The side of each lateral cone 6 is close to the inner wall of the cylinder 1 and fixedly connected to the cylinder 1. The multiple lateral cones 6 are evenly distributed along the circumference of the cylinder 1. The axis of the lateral cone 6 is close to the inner wall of the cylinder 1, and the outer edge of the lateral cone 6 is close to the chassis 5. The thickness of the lateral cone 6 gradually increases from the center of the cylinder 1 to the side wall of the cylinder 1, so that the box 4 can slide onto the lateral cone 6 more smoothly during the sliding process, thereby adjusting the posture of the box 4 (the posture of the box 4 will be different at different height positions on the lateral cone 6).
[0037] Multiple cameras 2 are installed on the upper inner side of the cylinder 1. The multiple cameras 2 are set along the circumference of the cylinder 1 corresponding to the position of the lateral cone 6. The cameras 2 can then capture the barcodes on the box 4 on the chassis 5 and the lateral slide 6 to obtain the drug information and consumable information corresponding to the barcodes on the box 4.
[0038] A spoke assembly 3 is provided on the chassis 5. The spoke assembly 3 includes a central cone 31, which is located at the center of the chassis 5. The bottom of the central cone 31 passes through the chassis 5 and is connected to a drive motor (the drive motor can be installed on the bottom surface of the chassis 5 or on the side wall of the cylinder 1 located below the chassis 5). The drive motor drives the central cone 31 to rotate around its axis on the chassis 5 (the connection method between the central cone 31 and the drive motor is prior art, which can be implemented by those skilled in the art based on common knowledge and prior art without creative effort). Multiple push bars 32 are arranged circumferentially around the central cone 31. The push bars 32 are arranged along the circumference of the chassis 5 and are all close to the chassis 5 (that is, the push bars 32 are located above the chassis 5, and the gap between them is small (usually 2-5mm), so that the push bars 32 can be suspended above the chassis 5 and can rotate together with the central cone 31).
[0039] The device works as follows: Staff or dispensing machines pick up the corresponding medicines and consumables according to the prescription and place them inside the cylinder 1; the camera 2 on the cylinder 1 photographs the medicine and consumable boxes 4 inside the cylinder 1, obtaining the corresponding barcode information on the boxes; when the barcode information on the boxes 4 is obscured, the spoke assembly 3 rotates, causing the pusher 32 to rotate on the chassis 5. The rotating pusher 32 pushes the boxes 4 to rotate and move them closer to the cylinder 1, adjusting the position of the boxes 4 accordingly; when the boxes 4 are pushed (slid) towards the lateral cone 6 by the pusher 32, ... Under the influence of inertia and the push bar 32, the box 4 gradually slides onto the lateral cone 6, and adjusts its posture (the posture of the box 4 will be different at different heights on the lateral cone 6), so that the barcode information on the medicine and consumable box 7 is fully exposed to the shooting angle of a certain camera, and the camera acquires the complete barcode on the medicine and consumable box 7, and then the spoke assembly 3 stops rotating; the background compares, associates and stores the medicine information, consumable information and patient information corresponding to the barcode information (for subsequent traceability of medicine and consumables), and takes out the medicine and consumable box 7 from the cylinder 1.
[0040] Example 2
[0041] Based on Embodiment 1, in order to facilitate the smoother sliding of the box 4 onto the lateral cone 6, the lateral cone 6 is installed above the chassis 5, and a passage gap is left between the bottom surface of the lateral cone 6 and the top surface of the chassis 5 (this passage gap allows the rotating push bar 32 to pass through).
[0042] The free end of push bar 32 is close to the inner side of cylinder 1.
[0043] During operation, the push bar 32 rotates with the central cone 31 and sweeps across the chassis 5. When the push bar 32 approaches the lateral cone 6, it can pass through the gap. Because the push bar 32 is long enough, it can effectively push the box 4 and make it slide onto the lateral cone 6.
[0044] Example 3
[0045] Based on Embodiment 1 or Embodiment 2, this embodiment provides a specific structure for the pusher 32.
[0046] The push bar 32 includes an L-shaped connector 322. The inner side of the horizontal bar of the L-shaped connector 322 is fixedly connected to the central cone 31, and the bottom of the vertical bar of the L-shaped connector 322 is connected to the spokes 321. Of course, by reasonably setting the number of push bars 32 arranged circumferentially around the central cone 31, the outer diameter of the central cone 31, the width of the L-shaped connector 322, and adjusting the spacing between the vertical bars of the L-shaped connector 322, it is possible to effectively prevent the box body 4 from getting stuck under the central cone 31 and between the L-shaped connectors 322.
[0047] The spoke 321 has a certain degree of rigidity, allowing it to remain suspended above and close to the chassis 5 for extended periods. It also possesses a degree of flexibility, enabling it to deform when encountering a heavy box 4 or when the box 4 is jammed, thus preventing the entire mechanism from jamming or malfunctioning. The spoke 321 can be made from existing materials; those skilled in the art can select and apply suitable materials based on their needs without requiring any inventive effort.
[0048] Example 4
[0049] Based on the above embodiments, the spokes are set to be arc-shaped. The rotating arc-shaped spokes can push the box to rotate on the chassis while sliding outwards. During the movement of the box, it can slide onto the lateral cone more smoothly, making it easier to adjust the posture of the box on the lateral cone and making it easier to fully expose the barcode on the box to the camera's shooting range.
[0050] Example 5
[0051] Based on the above embodiment, the cross-section of the spoke 321 is set as a triangle, and the bottom surface of the spoke 321 is parallel and close to the chassis 5.
[0052] By setting the cross-section of the spokes 321 to be triangular, the box 4 can be rotated by the spokes 321 in both forward and reverse rotation. When encountering greater resistance, the box 4 can pass over the spokes 321 and be pushed by the next spoke 321.
[0053] Preferably, multiple protrusions and depressions 323 can be provided at the top edge of the spoke 321. These protrusions and depressions 323 can be upward protrusions, downward depressions, or planar structures parallel to or at a certain angle to the bottom surface of the spoke 321. The multiple protrusions, depressions, and planar structures are distributed along the length of the spoke (321). Therefore, as the box 4 passes over the spoke 321, the posture of the box 4 can be adjusted by the protrusions and depressions 323 so that the camera 2 can capture its complete barcode information.
[0054] Example 6
[0055] Based on Examples 1-5, in order to better drive the box 4 to roll inside the cylinder 1, the chassis 5 can be set as an inclined plane, that is, the plane of the chassis 5 has an angle θ with the horizontal plane.
[0056] As a preferred option, protrusions and grooves of varying sizes can also be provided on the top surface of the chassis 5 (the arrangement, distribution, and size of the protrusions and grooves can be determined by those skilled in the art based on the actual situation; of course, if the size of the protrusion is appropriate, the protrusion and the housing 4 will not obstruct the movement of the spokes 321; similarly, if the size of the groove is appropriate, the groove and the housing 4 will not obstruct the movement of the spokes 321).
[0057] Since the chassis 5 is set as an inclined plane, the spoke assembly 3 is also set as inclined (that is, the axis of the central cone 31 is perpendicular to the chassis 5).
[0058] When in use, the spokes 321 sweep close to the top surface of the chassis 5. When the box 4 is blocked, the spokes 321 will push the box 4 to move or even flip, thereby adjusting the posture of the box 4 so that the barcode on the box 4 can be fully exposed and captured by the camera 2.
[0059] Example 7
[0060] Based on embodiments 1-5, in order to better drive the box 4 to tumble inside the cylinder 1, the base 5 can be set as a conical surface with a taper of 60:1 to 70:1. Similarly, the central cone 31 is set at the top of the cone along the axis of the base 5, and the spokes 321 are set along the conical surface. When the spokes 321 rotate, they sweep close to the top surface of the base 5.
[0061] As a preferred option, protrusions and grooves of varying sizes can also be provided on the top surface of the chassis 5 (the arrangement, distribution, and size of the protrusions and grooves can be determined by those skilled in the art based on the actual situation; of course, if the size of the protrusion is appropriate, the protrusion and the housing 4 will not obstruct the movement of the spokes 321; similarly, if the size of the groove is appropriate, the groove and the housing 4 will not obstruct the movement of the spokes 321).
[0062] Since the chassis 5 is set as an inclined plane, the spoke assembly 3 is also set as inclined (that is, the axis of the central cone 31 is perpendicular to the chassis 5).
[0063] In use, the spokes 321 sweep across the top surface of the chassis 5 (there is a gap between the spokes 321 and the top surface of the chassis 5, which can be determined by those skilled in the art based on the actual situation without creative effort; as long as the spokes 321 rotates, it can effectively push the box 4 without causing the box 4 to get stuck in the gap between the spokes 321 and the chassis 5, thus affecting the normal operation of the spokes 321). When the box 4 is blocked, the spokes 321 will push the box 4 to move or even flip, thereby adjusting the posture of the box 4 so that the barcode on the box 4 can be fully exposed and captured by the camera 2.
[0064] Example 8
[0065] Based on the above embodiments, a controller is provided on the outer wall of the frame 1, and a communication chip is provided inside the controller. This communication chip can be a 4G chip, a 5G chip, or other communication chip. The controller is electrically connected to the drive device of the central cone 31, the camera 2, and the communication chip.
[0066] In addition, a battery is installed on the frame 1, which can provide power to the controller, camera 2, and drive device of the central cone 31.
[0067] In this embodiment, by setting a controller on the cylinder 1, the controller can rotate the central cone 31 according to the image of the medicine and consumable box 7 obtained by the camera 2 in real time. The posture of the medicine and consumable box 4 inside the cylinder can be adjusted by the cooperation of the spokes 321 and the lateral cone 6. After a certain camera 2 obtains accurate and complete barcode information on the prescription and medicine box 4, the medicine and consumable information is transmitted to the medical institution server through the communication chip (4G chip, 5G chip or WIFI chip, etc.), realizing the data association between the medicine and consumable information and the patient information and other related information, which facilitates the subsequent traceability of medicines and consumables.
