Description

Technical Field

[0001] The present invention relates to the technical field of smart medicine cabinets, and in particular to an Internet-based smart medicine cabinet medicine storage and retrieval system. Background Art

[0002] With the accelerated digital transformation of the healthcare industry, smart medicine cabinets, as core equipment for refined drug management, have been widely used in hospitals, community clinics, and nursing homes. They optimize drug storage, dispensing, and distribution processes through information technology, significantly improving drug management efficiency and reducing the risk of medication errors caused by manual operations. They have become a key support for ensuring medical safety and improving service quality.

[0003] However, the existing Internet-based smart medicine cabinet storage and retrieval system has many limitations during use. Because traditional medicine cabinets are mostly fixed structures, they are difficult to adjust according to the layout of medical facilities or to move quickly to meet emergency needs, which greatly limits their flexibility. Furthermore, in terms of drug management, although existing medicine cabinets have basic storage functions, they lack an efficient classification management mechanism. The drug storage location is fixed and cannot be dynamically adjusted according to the frequency of drug use, shelf life, etc., resulting in low storage and retrieval efficiency.

[0004] Traditional smart medicine cabinets have no corresponding application capacity for the storage volume of medicines. When a single storage unit has too much storage, medical staff frequently open the storage cylinder to access medicines, which increases the number of times the medicines are exposed to the external environment, causing temperature and humidity fluctuations or external contamination to affect the quality of the medicines. In addition, the storage location of medicines is random, which can easily lead to frequently used medicines being placed in inconvenient areas such as the upper, lower or inner parts of the cabinet. Medical staff need to bend over, tiptoe or move the cabinet to complete the operation, resulting in low storage and retrieval efficiency, and may even cause safety hazards such as accidental or missed access due to inconvenient operation.

[0005] Therefore, the above technical problems need to be solved. Summary of the Invention

Through the control screen 6 and the operation slot 5, operator information, alarm information, peripheral status, date and time can be logged in at all times. Through the information management of the scanning module and the control screen 6, the efficiency of drug inventory is improved by about 60%. In the past, it took 30 to 40 minutes to manually inventory the drugs in a medicine cabinet. The smart medicine cabinet can shorten the inventory time to 12 to 16 minutes.

[0043] In the present invention, the opening and closing mechanism includes a servo motor 15 installed on both sides of the lower end of the cabinet 1, the output end of the servo motor 15 is clamped with the middle of the rotating ring 16, and a moving block 17 is hinged at one end of the rotating ring 16. The moving block 17 is slidably clamped in the sliding grooves opened inside the recovery bin door 3 and the medicine bin door 4. The recovery bin door 3 and the medicine bin door 4 are used to facilitate storage according to the conditions of different medicines; a back panel 10 is fixedly installed on the back of the cabinet 1 by bolts, and a power switch slot 9 is opened at one end of the cabinet 1, and a power switch is installed inside the power switch slot 9. The use and maintenance of the smart medicine cabinet are facilitated by the back panel 10 and the power switch slot 9; the moving mechanism includes a servo motor 15 fixedly installed on The linear motors 11 and guide blocks on both sides of the recovery bin and the medicine bin are movably installed with movable seats in the linear motors 11 and the guide blocks, and the movable seats are fixedly connected with movable plates 12 and storage plates 13 respectively. A plurality of storage holes are equidistantly provided on the movable plate 12, and the lower ends of the storage holes in the movable plate 12 are fixedly connected with storage cylinders 14. The linear motors 11, the movable plates 12 and the storage plates 13 are convenient for storing medicines and waste liquid medicines, and a Bluetooth weighing electronic scale can be placed in the storage cylinder 14 as needed to weigh the waste liquid. About 85% of medical staff said that the information management function of the smart medicine cabinet helps to improve the standardization and safety of drug management.

[0044] The medicine storage and retrieval system of the smart medicine cabinet also includes a collection module, an analysis module and an execution module;

[0045] The collection module collects the access data and dosage data of drugs, the height data of medical staff, and transmits the collected data to the analysis module;

[0046] The analysis module analyzes the access and usage data transmitted by the acquisition module to determine whether the storage data inside the smart medicine cabinet needs to be adjusted. If so, it generates a storage adjustment signal and transmits the storage adjustment signal to the execution module. The analysis module also analyzes the height data transmitted by the acquisition module to determine the optimal access area. If it is found that the corresponding medicine is not placed in the optimal access area, it generates a position adjustment signal and transmits the position adjustment signal to the execution module.

[0047] Taking one week as the set time period, retrieve the access data and usage data of various drugs within multiple historical set time periods away from the current time period, and then sort the retrieved data according to the length of time between its corresponding set time period and the current time period;

[0048] "No change in dosage" is defined as a fluctuation of ≤5% in drug inventory after a single access operation. For example, if there are 10 bottles of a drug in stock, and the inventory remains at 10 or 9 bottles (error ≤ 1 bottle) after an access operation, it is considered an error. This threshold can be adjusted in the system settings, ranging from 2% to 10%. Error records are stored separately, including the operation time, operator ID, and drug information, to facilitate subsequent audit and traceability. For drugs that have been repeatedly mishandled, the system automatically marks them as "easy-to-touch drugs" and recommends that they be stored in an area where they are not easily touched.

[0049] By comparing the access times and dosage data of the corresponding medicine within the set time period, if the dosage data of the medicine corresponding to the access times has not changed, it is determined that the operation corresponding to the access times is an erroneous operation, not a real access operation, and the access times are not counted; the corresponding days of real access operations within the set time period are counted. Record the total number of actual accesses within the set time period and divide it by the number of days. , get the actual access frequency data for the week; divide the total usage data of the actual access in the set time period by the number of days , get the actual average usage data for the week ;

[0050] “Number of days corresponding to actual access operations” The statistics exclude the following situations: equipment maintenance days, system failure periods, and non-working hours during holidays; for example, in a week of 7 days, the medicine cabinet is out of service for 1 day due to maintenance, and the actual effective days are 6 days; the average weekly access frequency The calculation formula is ,in The data is the actual number of accesses per day. The system supports statistics by three time dimensions: weekly, monthly, and quarterly. The default display is the data for the past four weeks. Medical staff can switch the time range through the control screen. The data chart shows the trend changes in the form of a line graph.

[0051] Sort the single usage data of actual access within the set time period, and sort the corresponding single usage data with the same quantity. If the record , then the usual dosage of medicine taken by medical staff is determined to be the quantity Corresponding single dosage data , is the preset scale factor, The total amount corresponding to the single dosage data; the average storage volume of the corresponding medicine at a single storage hole or a single storage cylinder 14 in the smart medicine cabinet To obtain, if , then generate the inventory adjustment signal and pass the inventory adjustment signal to the execution module; if , then the storage volume is averaged and average usage data For comparison, if Not present If the quantity is within the range, the inventory adjustment signal is also generated and passed to the execution module. is the preset proportional coefficient;

[0052] Preset scale factor The recommended value is 0.3, that is, when the frequency of a single dose occurs Exceeded total number of times When it is 30% of the usual dosage, it is determined to be the usual dosage. For example, if a drug is taken 10 times in a week, and 5 bottles are taken 6 times, then , , , so If the storage volume is If the number of sticks is too high, the system will generate a stock adjustment signal and recommends adjusting the storage capacity to 5 sticks per grid. When the system uses the dynamic threshold method, With average dosage of Range comparison, The default value is 0.2, that is Need to range, otherwise adjustment is triggered;

[0053] After the execution module receives the inventory adjustment signal, when the medical staff stores the corresponding medicine, the warning module in the medicine storage and retrieval system will sound a buzzer warning and display the corresponding target adjustment amount on the control screen 6. or , which makes it convenient for medical staff to adjust the storage volume of medicines.

[0054] The product of the access frequency data and the average usage data of the corresponding drug in the set time period is used as the total usage data of the set time period. Then, the usage data and total inventory data of the drug that have been taken this week are obtained. The difference between the total usage data and the taken usage data is used as the remaining demand data, and the difference between the total inventory data and the taken usage data is used as the remaining inventory data. The remaining inventory data is compared with the remaining demand data. If the remaining inventory data is less than the remaining demand data, a replenishment signal is generated and transmitted to the execution module.

[0055] After receiving the replenishment signal, the execution module sends the replenishment signal and replenishment drug information to the replenishment staff recorded in the background through the signal transmission device installed on the control panel 6.

[0056] The image data of the medical staff who come to perform access operations is acquired through the monitoring camera 8 (the image data is collected after the medical staff stands still in front of the medicine cabinet for a preset time). By grayscale processing and grayscale value comparison of the image data (if the grayscale comparison shows that the white coat is not in a vertical state, the image data is acquired again), it is determined whether the person coming is a medical staff (the medical staff is wearing a white coat). If it is determined to be a medical staff, the height data of the medical staff's outline is acquired by grayscale processing the image; if it is determined to be not a medical staff, the height data is not acquired (the smart medicine cabinet is also equipped with a fingerprint recognition module. If the medical staff is not wearing a white coat, the fingerprint comparison can be used to identify whether it is a medical staff); the height data of all medical staff who come to perform access operations are removed from the extreme values ​​and averaged, and then the access frequency of each type of medicine is retrieved and arranged in order according to the size of the access frequency data, and the average of these access frequency data is calculated. and standard deviation ,by Filter the access frequency data for the range and More range than scope The access frequency data in the partition is a partition. Based on the height differences of medical staff, the smart medicine cabinet is set at 1m above the ground as the optimal access area. The difficulty of storage increases from the optimal access area to the upper and lower positions, and the difficulty at the lower position is less than that at the upper position.

[0057] Arrange the medicines in descending order of access frequency, and then compare the placement of medicines with corresponding access frequencies according to the sorting. When it is found that the corresponding medicine is not placed in the optimal access area, a position adjustment signal is generated and transmitted to the execution module. After the system sorts the medicines from high to low in access frequency, the linear motor of the moving mechanism adjusts the position of the medicines. The adjustment priority follows the principle of "high frequency first, near expiration date first", that is, medicines with high access frequency are adjusted first, and if the frequencies are the same, medicines with near expiration date are adjusted first. After each adjustment operation, the system records the position information and timestamps before and after the adjustment to form a position optimization log for management personnel to evaluate the adjustment effect.

[0058] After receiving the position adjustment signal, the execution module will give priority to adjusting the storage position to the optimal access area when medical staff store medicines with high access frequency, and will give priority to taking the corresponding medicines in the non-optimal access area when medical staff take medicines with high access frequency.

[0059] Working principle: When the present invention is used, first, the universal wheel 2 installed at the bottom of the cabinet 1 is used to give the smart medicine cabinet flexible mobility, so that medical staff can adjust the position of the medicine cabinet according to actual needs. Then, the medicine cabinet is turned on by the power switch in the power switch slot 9. At this time, the staff can operate on the control screen 6. The scanning module in the operation slot 5 and the corresponding position of the lower cabinet 1 can scan the drug barcode, staff identity information, etc., to realize the management of drug entry and exit and the identification of operation authority. The control button can assist in completing specific function operations. The monitoring camera 8 is installed on the fixed frame 7 to monitor the surrounding area and operation status of the medicine cabinet in real time to ensure the safety of drug use. Then, when it is necessary to access drugs or process recycled items, the servo motor 15 installed on both sides of the lower end of the cabinet 1 receives the control command and drives the rotating ring 16 at the output end to rotate. Since a moving block 17 is hinged at one end of the rotating ring 16, and the moving block 17 is slidably engaged in the sliding groove opened inside the recovery bin door 3 and the medicine bin door 4, the rotation of the rotating ring 16 drives the moving block 17 to move in the sliding groove, thereby realizing the opening and closing of the recovery bin door 3 and the medicine bin door 4, which is convenient for medical staff to take, store and process recycled items. When the recovery bin door 3 and the medicine bin door 4 are opened and closed to the maximum, after the staff inputs the drug access instruction on the control panel 6, the linear motor 11 is started to drive the moving plate 12 and the storage plate 13 to move, and then the storage holes and storage cylinders 14 on the moving plate 12 are used to classify and store drugs. The moving plate 12 can move the corresponding drugs to a position that is convenient for taking, and the storage plate 13 can be used to place items to be recycled or temporarily store drugs, thereby realizing orderly management and efficient access of drugs and recycled items.

[0060] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.

If it is determined to be a medical staff, the height data of the medical staff's outline is obtained by grayscale processing the image; if it is determined to be a non-medical staff, the height data is not obtained; K2: Remove extreme values ​​and calculate the mean of the height data of all medical staff who come to perform access operations, then retrieve the access frequency of various types of medicines, arrange them in order according to the size of the access frequency data, and calculate the mean of these access frequency data and standard deviation ,by Filter the access frequency data for the range and More range than scope The access frequency data in the partition is a partition. Considering the height differences of medical staff, the smart medicine cabinet is set at 1m above the ground as the optimal access area; K3: Arrange the medicines in descending order of access frequency, and then compare the placement positions of the medicines with corresponding access frequencies according to the sorting. When it is found that the corresponding medicine is not placed in the optimal access area, a position adjustment signal is generated and passed to the execution module.
