[0005] System integration: Integrate the inventory management system with other systems such as the hospital information system (HIS) to achieve data sharing.
[0006] The above technologies have the following defects: low accuracy: barcodes are easily worn and contaminated, resulting in low recognition rate; RFID technology has poor recognition effect in metal, liquid and other environments. Failure to update inventory data in a timely manner may result in statistical data not matching actual inventory. More manual intervention: inventory counting, data entry and other links still require a lot of manual participation, which is inefficient. Summary of the invention
[0007] In order to solve the defects of the above-mentioned medical device inventory management technology, the present invention provides a medical device inventory real-time statistics method and device. The following technical solutions are adopted:
[0008] A real-time statistical method for medical device inventory, which divides a medical device warehouse into multiple storage areas according to physical areas, installs a chip-based regional inventory data preprocessing module on the roof of the central area of each storage area, installs a plane linear track label scanning device on each shelf, and the plane linear track label scanning device is provided with a wireless electronic tag scanner based on short-range wireless communication technology. When each medical device is put into storage, a wireless electronic tag based on short-range wireless communication technology is attached to the outer packaging;
[0009] The real-time statistical method for medical device inventory includes the following steps:
[0010] Step 1: At set intervals, the planar moving mechanism of the planar linear track label scanning device drives the wireless electronic tag scanner to scan multiple wireless electronic tags of multiple medical devices stored on the shelf one by one, and obtain data of multiple electronic tags on the shelf;
[0011] Step 2: After completing a complete scan, the wireless electronic tag scanner adds time tag data and shelf tag data to multiple electronic tag data to form an inventory inspection data packet, and transmits the inventory inspection data packet to the corresponding regional inventory data preprocessing module;
[0012] Step 3: The regional inventory data preprocessing module analyzes the inventory inspection data packets of all shelves in the region in sequence according to the received time sequence, obtains the medical device inventory data based on the shelf label data, and counts and calculates the medical device inventory data to obtain the regional medical device inventory statistical data;
[0013] Step 4, multiple regional inventory data preprocessing modules respectively add current time tag data to regional medical device inventory statistical data and send them to the warehouse management computer;
[0014] Step 5: The warehouse management computer aggregates the regional medical device inventory statistical data of multiple regional inventory data preprocessing modules to obtain the total inventory data of the medical devices at the current inventory time.
[0015] By adopting the above technical solution, by dividing the medical device warehouse into multiple storage areas according to physical areas, multiple storage areas can be managed in zones. The regional inventory data preprocessing modules in the multiple storage areas collect the electronic tag data scanned by multiple plane linear track label scanning devices within the regional range once every set time. The set time can be six hours, twelve hours or twenty-four hours, or scanning is performed every time there is a new entry or exit from the warehouse, thereby greatly improving the efficiency and accuracy of inventory counting.
[0016] During the specific scanning, the plane moving mechanism can be a plane electric slide, which can be installed on the inner side of the shelf, and the side of the outer packaging of the medical device with the wireless electronic tag is facing the side where the plane linear track label scanning device is installed. When the plane moving mechanism of the plane linear track label scanning device drives the wireless electronic tag scanner to move on the side of the shelf, it can cover all the multiple wireless electronic tags of multiple medical devices stored on the shelf, thereby automatically realizing the electronic tag scanning;
[0017] Each regional inventory data preprocessing module only receives inventory inspection data packets within the area, avoiding transmission obstacles under the coverage of the wireless network in the warehouse. The edge layout of multiple regional inventory data preprocessing modules and the edge analysis of multiple regional inventory data preprocessing modules are mainly to obtain medical device inventory data based on shelf label data, and to obtain regional medical device inventory statistical data by counting and counting based on the medical device inventory data, thereby realizing edge data preprocessing. Finally, the warehouse management computer summarizes the regional medical device inventory statistical data of multiple regional inventory data preprocessing modules to obtain the total inventory data of medical devices at the current inventory time, saving human resources and computing power resources, and efficiently realizing real-time statistics of medical devices.
[0018] Optionally, the method further includes step 6, wherein the management computer displays the total inventory data at the current inventory time and inventory statistics of medical devices in multiple regions through a display.
[0019] By adopting the above technical solution, the management computer can control the display to display the total inventory data of the current inventory time and the inventory statistics of medical devices in multiple regions, so that the management personnel can have a more comprehensive understanding of the medical device inventory data.
[0020] Optionally, the method of dividing the medical device warehouse into multiple storage areas according to physical areas is:
[0021] Step a, determining an electronic map of the medical device warehouse, where the electronic map is a rectangle;
[0022] Step b, determine the largest circular area S according to the effective network coverage of the regional inventory data preprocessing module, take the inscribed square SQ of S, fill the square SQ in any corner Qa of the rectangle of the electronic map, mark the covered area as area SQS, and mark the two sides that fit the edges of the corner Qa as Ba and Bb respectively;
[0023] Step c, identify the shelf outline in area SQS, translate Ba and Bb to the corner by one meter respectively, calculate the shortest distance S between the outline and the translated Ba or Bb respectively, if all S are greater than 0.1 meter, record the area SQS after the translation of Ba and Bb as area SQSD, and determine area SQSD as the storage area labeled 1;
[0024] Step d, sequentially determining storage areas numbered 1, 2, ..., n, where n is the number of storage areas.
[0025] The purpose of dividing the medical equipment warehouse into physical areas by adopting the above technical solution is: under the premise of ensuring wireless network coverage, the complete shelf outline needs to be covered. For example, the regional inventory data preprocessing module uses wireless Bluetooth and wireless electronic tag scanner to achieve short-range wireless communication. If the effective coverage range of wireless Bluetooth is a circular area with a diameter of 20 meters, then the inscribed square SQ of S can be taken. The side length of SQ is about 14.14 meters. Ba and Bb are translated to the corner by one meter respectively. At this time, the side length becomes 13.14 meters. The closest distance S between the outline and the translated Ba or Bb is calculated respectively. If all S are greater than 0.1 meters, the quality of wireless communication coverage is guaranteed, and the complete shelf outline is covered, thereby ensuring the wireless network communication for wirelessly collecting inventory data in the storage area.
[0026] Optionally, in step 1, the plane linear track label scanning device performs a complete scan every 1-6 hours, and the time for the complete scan does not exceed 10 minutes.
[0027] Optionally, in step 1, the planar moving mechanism of the planar linear track label scanning device drives the wireless electronic tag scanner to obtain a visual image directly in front during the planar movement, identifies the position of the wireless electronic tag based on a visual recognition algorithm, controls the wireless electronic tag scanner to approach multiple wireless electronic tags one by one to complete the wireless scanning, and reads multiple electronic tag data of multiple wireless electronic tags respectively.
[0028] By adopting the above technical solution, since the outer shape of the outer packaging of medical devices on the shelf is determined and the position of the wireless electronic tag is not fixed, the visual recognition algorithm can quickly confirm the position of the wireless electronic tag, so that the wireless electronic tag scanner approaches multiple wireless electronic tags one by one to complete the wireless scanning, thereby increasing the success rate of the wireless scanning.
[0029] Optionally, in step 3, the format of the inventory inspection data packet is TGI, where T is the radio scanning time tag data, G is the shelf label data, I is the medical device inventory data, the format of the medical device inventory data is ABCD, A is the name of the medical device, B is the type of medical device, C is the production date data, expiration date data and warehousing time data, and D is the quantity of medical devices.
[0030] Optionally, in step 3, the method for counting and statistics based on medical device inventory data is: first parse the medical device inventory data ABC, read the medical device type B, match B with the existing medical device types, and if there is a successful match, read the medical device quantity data of D, and add the medical device quantity data to the number of successfully matched medical device types to complete the counting and statistics.

When the slider moves in a plane, the wireless electronic tag scanner is driven to move in a plane on the side of the shelf. When the slider is close to the wireless electronic tag, the electronic tag data of the wireless electronic tag is wirelessly scanned.
[0032] The regional inventory data preprocessing module includes a wireless transmission module, a memory and a data analysis chip. The wireless transmission module is wirelessly connected to the wireless electronic tag scanner to exchange inventory inspection data packets. The memory is communicatively connected to the wireless transmission module. The data analysis chip is communicatively connected to the memory.

[0043] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0044] The embodiment of the invention discloses a real-time statistical method and device for medical device inventory.
[0045] Reference Figure 1-Figure 3Embodiment 1, a real-time statistical method for medical device inventory, divides a medical device warehouse into multiple storage areas according to physical areas, installs a chip-based regional inventory data preprocessing module on the roof of the central area of each storage area, installs a plane linear track label scanning device on each shelf 100, and the plane linear track label scanning device is provided with a wireless electronic tag scanner 11 set based on short-range wireless communication technology, and a wireless electronic tag 2 set based on short-range wireless communication technology is attached to the outer packaging of each medical device when entering the warehouse;
[0046] The real-time statistical method for medical device inventory includes the following steps:
[0047] Step 1: At set intervals, the plane moving mechanism 12 of the plane linear track label scanning device drives the wireless electronic tag scanner 11 to scan the wireless electronic tags 2 of the medical devices stored on the shelf 100 one by one, and obtain the data of the electronic tags on the shelf 100;
[0048] Step 2, after completing a complete scan, the wireless electronic tag scanner 11 packages the multiple electronic tag data with the time tag data and the shelf tag data to form an inventory inspection data packet, and transmits the inventory inspection data packet to the corresponding regional inventory data preprocessing module;
[0049] Step 3: The regional inventory data preprocessing module analyzes the inventory inspection data packets of all shelves 100 in the region in sequence according to the received time sequence, obtains the medical device inventory data based on the shelf label data, and performs counting and statistics based on the medical device inventory data to obtain regional medical device inventory statistical data;
[0050] Step 4, multiple regional inventory data preprocessing modules respectively add current time tag data to regional medical device inventory statistical data and send them to the warehouse management computer 3;
[0051] Step 5, the warehouse management computer 3 aggregates the regional medical device inventory statistical data of multiple regional inventory data preprocessing modules to obtain the total inventory data of the medical devices at the current inventory time.
[0052] By dividing the medical device warehouse into multiple storage areas according to physical areas, multiple storage areas can be managed in different areas. The regional inventory data preprocessing module in the multiple storage areas collects the electronic tag data scanned by multiple plane linear track label scanning devices within the area at set time intervals. The set time can be six hours, twelve hours or twenty-four hours, or each time there is a new entry or exit, the scanning is performed, which greatly improves the efficiency and accuracy of inventory counting;
[0053] During the specific scanning, the plane moving mechanism 12 can be a plane electric slide, which can be installed on the inner side of the shelf 100, and the side of the outer packaging of the medical device with the wireless electronic tag 2 is facing the side where the plane linear track label scanning device is installed. When the plane moving mechanism 12 of the plane linear track label scanning device drives the wireless electronic tag scanner 11 to move on the side of the shelf 100, it can cover all the multiple wireless electronic tags 2 of the multiple medical devices stored on the shelf 100, thereby automatically realizing the electronic tag scanning;
[0054] Each regional inventory data preprocessing module only receives inventory inspection data packets within the area, avoiding transmission obstacles under the coverage of the wireless network in the warehouse. The edge layout of multiple regional inventory data preprocessing modules and the edge analysis of multiple regional inventory data preprocessing modules are mainly to obtain medical device inventory data based on shelf label data, and to obtain regional medical device inventory statistical data by counting and counting based on the medical device inventory data, thereby realizing edge data preprocessing. Finally, the warehouse management computer 3 summarizes the regional medical device inventory statistical data of multiple regional inventory data preprocessing modules to obtain the total inventory data of medical devices at the current inventory time, saving human resources and computing power resources, and efficiently realizing real-time statistics of medical devices.
[0055] Embodiment 2 further includes step 6, wherein the management computer 3 displays the total inventory data at the current inventory time and inventory statistics of multiple regional medical devices through the display 5.
[0056] The management computer 3 can control the display 5 to display the total inventory data of the current inventory time and the inventory statistics of medical devices in multiple regions, so that the management personnel can have a more comprehensive understanding of the inventory data of medical devices.
[0057] Embodiment 3, the method of dividing a medical device warehouse into multiple storage areas according to physical areas is:
[0058] Step a, determining an electronic map of the medical device warehouse, where the electronic map is a rectangle;
[0059] Step b, determine the largest circular area S according to the effective network coverage of the regional inventory data preprocessing module, take the inscribed square SQ of S, fill the square SQ in any corner Qa of the rectangle of the electronic map, mark the covered area as area SQS, and mark the two sides that fit the edges of the corner Qa as Ba and Bb respectively;
[0060] Step c, identifying the outline of the shelf 100 in the area SQS, translating Ba and Bb to the corner by one meter respectively, calculating the closest distance S between the outline and the translated Ba or Bb respectively, if all S are greater than 0.1 meters, recording the area SQS after the translation of Ba and Bb as the area SQSD, and determining the area SQSD as the storage area numbered 1;
[0061] Step d, sequentially determining storage areas numbered 1, 2, ..., n, where n is the number of storage areas.
[0062] The purpose of dividing the medical equipment warehouse into physical areas is: under the premise of ensuring wireless network coverage, the complete outline of the shelf 100 needs to be covered. For example, the regional inventory data preprocessing module uses wireless Bluetooth and the wireless electronic tag scanner 11 to achieve short-range wireless communication. If the effective coverage range of wireless Bluetooth is a circular area with a diameter of 20 meters, then the inscribed square SQ of S can be taken. The side length of SQ is about 14.14 meters. Ba and Bb are translated to the corner by one meter respectively. At this time, the side length becomes 13.14 meters. The closest distance S between the outline and the translated Ba or Bb is calculated respectively. If all S are greater than 0.1 meters, the quality of wireless communication coverage is guaranteed, and the complete outline of the shelf 100 is guaranteed, thereby ensuring the wireless network communication for wirelessly collecting inventory data in the storage area.
[0063] In Example 4, in step 1, the plane linear track label scanning device performs a complete scan every 1-6 hours, and the time for the complete scan does not exceed 10 minutes.

[0065] Because the outer shape of the medical device packaging on the shelf is fixed, the position of the wireless electronic tag 2 is not fixed. The use of a visual recognition algorithm can quickly confirm the position of the wireless electronic tag 2, so that the wireless electronic tag scanner 11 approaches multiple wireless electronic tags 2 one by one to complete the wireless scanning, thereby increasing the success rate of the wireless scanning.
[0066] The specific method of using the visual recognition algorithm to realize the position confirmation of the wireless electronic tag 2 is:
[0067] Visual images of medical device packaging captured using cameras;
[0068] Adjust image brightness, contrast, and resolution, and perform grayscale or binarization processing to improve the accuracy of image recognition.
[0069] Geometric features such as Hough transform are used to detect straight lines and thus infer the planar position of the tag.
[0070] Using template matching technology, the shape template of the wireless electronic tag 2 is matched with the collected image to realize position confirmation;
[0071] It can also be achieved through deep learning methods:
[0072] A convolutional neural network (CNN) is designed and trained to identify the locations of labels directly from images.
[0073] Use transfer learning to leverage pre-trained networks such as YOLO, SSD, or Faster R-CNN for location detection.
[0074] In Example 6, in step 3, the format of the inventory inspection data packet is TGI, where T is the radio scanning time tag data, G is the shelf tag data, I is the medical device inventory data, and the format of the medical device inventory data is ABCD, A is the name of the medical device, B is the type of medical device, C is the production date data, expiration date data and warehousing time data, and D is the number of medical devices.
