Description

Technical Field

[0001] The present invention belongs to the technical field of medicine management, and in particular relates to a medicine central control system and a method for managing medicine cabinets and medicines. Background Art

[0002] Medicines are an important means of preventing, treating and diagnosing diseases. The quality of medicines is directly related to the health and even life safety of patients. In hospitals, scientific research institutions and universities with a large number of medicines, in order to ensure the quality of medicines, the correct storage of medicines is particularly important.

[0003] Typically, labels are added to medicine containers and medicine cabinets, and medicines are stored according to the label contents. However, due to the lack of constraints in this process, the storage of medicines gradually becomes irregular over time, resulting in a decrease in the storage safety of medicines and ultimately affecting the quality of medicines.

[0004] In order to better and more rationally manage and control drugs in the long term, Chinese patent document CN113744833A records a drug central control system and its management method for medicine cabinets and drugs, including a central control console and a medicine cabinet. The central control console includes an equipment housing, an identity recognition module, an identification and weighing module, a communication module, a data processing module and a touch screen; the identity recognition module is used to obtain user information; the identification and weighing module is used for drug information identification and drug weighing; the communication module communicates with the medicine cabinet cloud service platform for drug access approval information and electronic record information of drug access quantity, and communicates with the smart lock of the medicine cabinet to control the opening and closing of the medicine cabinet door. The data processing module processes drug information and user identity information, and outputs the information on the touch screen; the touch screen provides a user management interface, provides drug inventory management, drug access control and display.

[0005] The above technical solution can effectively improve the convenience of drug management and control by centrally recording and managing data such as the storage, use, disposal, and balance of drugs. It mainly controls drugs by obtaining the status of drugs during the process of taking and placing drugs. However, after the drugs are stored in the medicine cabinet, they lose control. Some drugs are stored in unreasonable positions or are not sealed properly, which may easily lead to risks such as leakage. For drugs that leak, if they are not controlled for a long time, it may affect the quality of surrounding batches of drugs. Summary of the Invention

[0006] The purpose of the present invention is to provide a drug central control system and a management method for a medicine cabinet and drugs, so as to solve the problem of lack of control in the medicine cabinet during the drug management process, ensure the safe storage of drugs in the medicine cabinet, and ensure that drugs can be reasonably stored in the medicine cabinet.

[0007] In order to achieve the above-mentioned object, the technical solution of the present invention is as follows: a drug central control system includes an information entry module, an entry and exit detection module, an auxiliary module, a collection module and a processing module;

[0008] The information entry module is used to collect basic information of the medicine when it is first stored in the medicine cabinet. The basic information includes at least the weight and appearance of the medicine, and plans the storage location for the medicine;

[0009] The collection module is used to collect the weight of the planned storage location of the stored medicine, and determine whether the medicine is stored in the planned storage location according to the weight of the planned storage location of the stored medicine;

[0010] The entry and exit detection module is used to collect the medicines taken out or stored in the medicine cabinet, determine whether the medicines leave or return to the storage location based on the weight of the planned storage location of the stored medicines, and compare whether the medicines taken out or put into the medicine cabinet correspond to the medicines that leave or return to the storage location;

[0011] The auxiliary module is used to provide light inside the medicine cabinet each time the medicine cabinet is opened, and to delay the light interruption after the medicine cabinet is closed. The acquisition module is also used to capture images of the planned storage location of the medicines and its surrounding areas from above the planned storage location when the medicines are first stored in the medicine cabinet and during the delay period of light interruption after the medicine cabinet is closed, and output them as reference images and verification images.

[0012] The processing module is used to output drug storage prompts based on whether the drugs are stored in the planned storage location; compare the shadow areas in the reference image and the verification image, and output the drug storage status based on the weight changes of the drugs at the storage location.

[0013] Furthermore, the processing module is used to obtain the center of the medicine container when the medicine is first placed in the medicine cabinet, select a number of shadow edge points based on the shadow area in the reference image, calculate the distance between the center of the medicine container and each shadow edge point, and obtain the reference distance;

[0014] The processing module is further used to obtain the center of the medicine container after the medicine cabinet is closed, select a number of shadow edge points based on the shadow area in the verification image, calculate the distance between the center of the medicine container and each shadow edge point, and obtain the verification distance;

[0015] The reference distance is compared with the verification distance. When the difference between the reference distance and the verification distance exceeds a threshold, the drug storage status is output as abnormal position or sealing.

[0016] Furthermore, the information entry module is used to store the appearance of each drug container and generate a drug database;

[0017] The entry and exit detection module is used to continuously capture images of the opening area of ​​the medicine cabinet when the medicine cabinet is opened. The corresponding medicine container appearance is retrieved in the medicine database based on the captured medicine container appearance image, and the basic information of the taken out or stored medicine is output based on the search result. The storage location of the medicine is obtained based on the basic medicine information. The storage location of the medicine obtained based on the basic medicine information is compared to see whether it is the same as the storage location where the weight change occurs. If they are the same, it is determined that the medicine taken out or put into the medicine cabinet corresponds to the medicine that left or returned to the storage location; otherwise, they do not correspond.

[0018] Furthermore, the basic information also includes the drug production date, drug shelf life and the drug's suitable storage environment; the information entry module is used to plan the storage location according to the drug's suitable storage environment; the processing module is used to record the drug's expiration date based on the drug's production date and drug shelf life, and output a drug expiration reminder when the drug's expiration date is less than a threshold.

[0019] Furthermore, the processing module is used to collect the weight change of the medicine at the storage location after the medicine is stored in the medicine cabinet and the medicine does not leave the storage location. When the weight change of the medicine exceeds a threshold, the output medicine storage status is that there is a risk of leakage;

[0020] The auxiliary module is used to receive the storage status of the medicines. When the storage status of the medicines indicates that there is a risk of leakage, the air in the area where the medicines with the risk of leakage are located is treated.

[0021] Furthermore, the processing module is used to record the frequency of each drug leaving or returning to the storage location. When the frequency of the drug leaving or returning to the storage location exceeds a threshold, the currently planned storage location of the drug is obtained and the planned storage location of the drug is adjusted.

[0022] The processing module is also used to output position adjustment information after the planned storage location of the medicine is adjusted.

[0023] Furthermore, the processing module is also used to summarize the medicine storage information in the medicine cabinet and display the medicine storage information; the processing module is also used to display the medicine storage prompts and medicine storage status.

[0024] A central medicine control system is a method for managing medicine cabinets and medicines, which is carried out through the central medicine control system mentioned above and includes the following steps:

[0025] When drugs are first stored in the medicine cabinet, basic information of the drugs is collected, including at least the weight and appearance of the drugs, and the storage location is planned for the drugs;

[0026] The weight of the medicine stored at the planned storage location is collected, and whether the medicine is stored in the planned storage location is determined according to the weight of the medicine stored at the planned storage location;

[0027] Collect the medicines taken out of or stored in the medicine cabinet, determine whether the medicines leave or return to the storage location based on the weight of the planned storage location of the stored medicines, and compare whether the medicines taken out of or put into the medicine cabinet correspond to the medicines that leave or return to the storage location;

[0028] Provide light inside the medicine cabinet every time the medicine cabinet is opened, and delay the light interruption after the medicine cabinet is closed;

[0029] When the medicine is first stored in the medicine cabinet and during the delayed interruption of illumination after the medicine cabinet is closed, images of the planned storage location of the medicine and its surrounding area are captured from above the planned storage location of the medicine, and output as a reference image and a verification image;

[0030] Output drug storage prompts based on whether the drugs are stored in the planned storage location; compare the shadow areas in the reference image and the verification image, and output the drug storage status based on the weight changes of the drugs at the storage location

[0031] Furthermore, the center of the medicine container when the medicine is first placed in the medicine cabinet is obtained, and a number of shadow edge points are selected based on the shadow area in the reference image, and the distance between the center of the medicine container and each shadow edge point is calculated to obtain the reference distance;

[0032] Obtain the center of the medicine container after the medicine cabinet is closed, select several shadow edge points based on the shadow area in the verification image, calculate the distance between the center of the medicine container and each shadow edge point, and obtain the verification distance;

[0033] The reference distance is compared with the verification distance. When the difference between the reference distance and the verification distance exceeds a threshold, the drug storage status is output as abnormal position or sealing.

[0034] The above scheme has the following beneficial effects:

[0035] 1. The present invention collects basic information of drugs when storing them, thereby allocating reasonable storage locations for the drugs and planning drugs with similar storage environments to be stored in the same area. Compared with random storage, it can more conveniently manage the drug environment in a unified manner and ensure that the drugs are stored in a suitable environment.

[0036] By comparing the stored medications with the planned storage locations, a reference image is generated if the storage locations correspond. This reference image serves as a benchmark for determining the subsequent storage status of the medications. The auxiliary module provides lighting and also serves as a reminder of the storage area. By comparing shadows, the storage status of multiple medications within the illuminated area can be simultaneously acquired. For example, if the lid of a medication container is not properly and completely closed, the shadow will lengthen while the light source position and medication storage location remain unchanged. Combined with the weight changes of the medications at the storage location, the status of the medications during storage can be monitored. Compared to simply checking whether the medications are stored correctly, this can improve the safety of medications stored in the medicine cabinet and avoid affecting the quality of the medications.

[0037] 2. The present invention uses image acquisition and comparison to determine whether the position of the medicines taken and placed each time is correct, and obtains the weight change of the medicines during storage in the medicine cabinet. If the weight change exceeds a threshold when the medicines are not taken out for use, there may be a risk of leakage or moisture. The auxiliary device can promptly process the area where the medicines leak or are damp. Compared with the existing technology, it can promptly determine whether the storage of medicines is normal, thereby reducing the harm caused to other medicines and the environment during storage in the medicine cabinet.

[0038] 3. The present invention records the frequency of taking and putting medicines. For medicines with a high frequency of taking and putting, it is appropriate to store them in a location that is easy to take and put. Therefore, the storage location of the medicines is re-planned. Compared with the management method of fixed storage location, it can improve the convenience of taking and putting medicines while ensuring the safe storage of medicines.

[0039] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0044] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "vertical", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0045] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal communication between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0046] The following is further described in detail through specific implementation methods:

[0047] The reference numerals in the drawings of the specification include: information input module 100, entry and exit detection module 200, auxiliary module 300, acquisition module 400, processing module 500, image collector 1, lamp 2, CCD image sensor 3, weighing sensor 4, exhaust channel 5.

[0048] Example 1

[0049] As attached Figure 1-3 As shown: the drug central control system includes an information input module 100, an entry and exit detection module 200, an auxiliary module 300, a collection module 400 and a processing module 500.

[0050] The information entry module 100 is used to collect basic information about medications when they are first stored in a medicine cabinet. This information includes at least the medication's weight and appearance, and to plan a storage location for the medications. The information entry module 100 can be located outside the medicine cabinet, allowing a single module to record information for multiple medicine cabinets. The module can capture the appearance and weight of newly stored medications through image capture and weight capture, respectively.

[0051] The collection module 400 is used to collect the weight of the planned storage location of the stored medicines, and determine whether the medicines are stored in the planned storage location according to the weight of the planned storage location of the stored medicines; Figure 2 As shown, there are several medicine storage areas in a medicine cabinet, and a weighing sensor 4 is set at the bottom of each medicine storage area. The weighing sensor 4 can obtain whether there is medicine stored above its corresponding position, and whether the weighing sensor 4 at the planned storage position collects the weight of the medicine collected by the information entry module 100. When the weight collected by the weighing sensor 4 matches the weight of the medicine, it indicates that the medicine is stored in the planned storage position.

[0052] The entry and exit detection module 200 is used to collect medicines taken out or stored in the medicine cabinet, determine whether the medicines leave or return to the storage location based on the weight of the planned storage location of the stored medicines, and compare whether the medicines taken out or put into the medicine cabinet correspond to the medicines that leave or return to the storage location.

[0053] Specifically, the information entry module 100 is used to store the appearance of each medicine container and generate a medicine database; the entry and exit detection module 200 is used to continuously capture images of the opening area of ​​the medicine cabinet when the medicine cabinet is opened, and retrieve the corresponding medicine container appearance in the medicine database based on the captured medicine container appearance image, output the basic information of the medicine taken out or stored based on the search result, and obtain the storage location of the medicine based on the basic information of the medicine; compare whether the storage location of the medicine obtained based on the basic information of the medicine is the same as the storage location where the weight change occurs. If they are the same, it is determined that the medicine taken out or put into the medicine cabinet corresponds to the medicine that leaves or returns to the storage location; otherwise, they do not correspond.

[0054] Combined with attachment Figure 2 As shown, by arranging CCD image sensors 3 on the left and right sides of the outer opening of each medicine storage area of ​​the medicine cabinet, the operation is started after the medicine cabinet door is opened, and images of the taken out or stored medicines are collected from the left and right sides. If higher precision image collection is required, CCD image sensors 3 can be arranged on the upper and lower sides of the outer opening of each medicine storage area. The basic information of the taken out or stored medicines can be quickly obtained by searching in the medicine database using the collected appearance images.

[0055] By determining whether the medicines taken out of or put into the medicine cabinet correspond to the medicines that leave or return to the storage location, the chance of the medicines being switched in the medicine cabinet can be avoided, ensuring that the storage location of the medicines remains appropriate and fixed.

[0056] The auxiliary module 300 is used to provide light inside the medicine cabinet every time the medicine cabinet is opened, and to delay the light interruption after the medicine cabinet is closed. Figure 2As shown, by arranging lamp tubes 2 on the side walls of each medicine storage area of ​​the medicine cabinet, the lamp tubes 2 are started and operated based on the opening of the medicine cabinet door and the basic information of the stored medicines, that is, only the lamp tubes 2 in the medicine storage area corresponding to the planned storage position of the medicines are started and operated. Therefore, when storing medicines, based on the opening of the lamp tubes 2, the approximate storage position of the medicines in the medicine cabinet can be quickly obtained.

[0057] The acquisition module 400 is also used to capture images of the planned storage location and its surrounding areas from above the planned storage location when the medicines are first stored in the medicine cabinet and during the delayed interruption of light after the medicine cabinet is closed, and output them as reference images and verification images. Figure 2 As shown, an image collector 1 is set at the top of each medicine storage area of ​​the medicine cabinet to collect reference images and verification images. There is only one image collector 1, and its position is fixed to ensure that the entire storage area can be covered.

[0058] Combined with attachment Figure 2 As shown, the lamp tubes 2 are all arranged on the side wall of the same side of each medicine storage area of ​​the medicine cabinet, ensuring that when the lamp tubes 2 are in operation, they illuminate the medicines in the medicine storage area to produce obvious shadow areas.

[0059] The processing module 500 is used to output drug storage prompts based on whether the drugs are stored in the planned storage location; based on the drug storage prompts, after each drug is stored, the user can be prompted whether the drug is stored correctly. The specific prompt method can be an audio prompt or an image prompt.

[0060] Basic information also includes the drug's production date, shelf life, and optimal storage environment. The information entry module 100 is used to plan storage locations based on the optimal storage environment. The processing module 500 is used to record the drug's expiration date based on the drug's production date and shelf life, and output a drug expiration reminder when the drug's expiration date is less than a threshold. Based on the drug expiration reminder, users can easily obtain the drug's shelf life.

[0061] Compare the shadow areas in the reference image and the verification image, and output the drug storage status based on the weight changes of the drugs at the storage location.

[0062] Specifically, the processing module is configured to obtain the center of the medicine container when the medicine is first placed in the medicine cabinet. Based on the shadow area in the reference image, several shadow edge points are selected. The distance between the center of the medicine container and each shadow edge point is calculated to obtain the reference distance. The processing module 500 is also configured to obtain the center of the medicine container after the medicine cabinet is closed. Based on the shadow area in the verification image, several shadow edge points are selected. The distance between the center of the medicine container and each shadow edge point is calculated to obtain the verification distance. The reference distance is compared with the verification distance. If the difference between the reference distance and the verification distance exceeds a threshold, the storage status of the medicine is output as a position or sealing abnormality.

[0063] For example, when the lid of a drug container is not completely closed, the shadow area of ​​the drug container in the verification image will change compared with the shadow area of ​​the drug container in the reference image. Based on the change in the shadow area, it is possible to determine whether the drug container is closed. Compared with the sensor monitoring method, it is possible to more quickly determine whether there is a risk of drug leakage.

[0064] The processing module 500 is used to collect the weight change of the medicine at the storage location after the medicine is stored in the medicine cabinet and the medicine has not left the storage location. When the weight change of the medicine exceeds a threshold, the output storage status of the medicine is that there is a risk of leakage.

[0065] The auxiliary module 300 is used to receive the storage status of the medicines, and when the storage status of the medicines indicates that there is a risk of leakage, the area where the medicines are located with the risk of leakage is processed. Figure 2 As shown, an independent air exhaust channel 5 is set in each medicine storage area of ​​the medicine cabinet, and the air in the medicine storage area of ​​the medicine cabinet where there is a risk of leakage is discharged through the air exhaust channel 5, so as to avoid long-term leakage of medicines causing damage to the medicine storage area of ​​the medicine cabinet.

[0066] Secondly, in order to enable users to more conveniently obtain the drug storage location and sample storage status, the processing module 500 is also used to summarize the drug storage information in the medicine cabinet and display the drug storage information; the processing module 500 is also used to display drug storage prompts and drug storage status, and the drug storage information, drug storage prompts and drug storage status can be displayed by setting a human-computer interaction interface.

[0067] The method for managing medicine cabinets and medicines through the above-mentioned medicine central control system includes the following steps:

[0068] S1: When the medicine is first stored in the medicine cabinet, the basic information of the medicine is collected, including at least the weight and appearance of the medicine, and the storage location is planned for the medicine;

[0069] S2: collecting the weight of the medicine at the planned storage location, and determining whether the medicine is stored in the planned storage location based on the weight of the medicine at the planned storage location;

[0070] S3: Collect the medicines taken out of or stored in the medicine cabinet, determine whether the medicines leave or return to the storage location based on the weight of the planned storage location of the stored medicines, and compare whether the medicines taken out of or put into the medicine cabinet correspond to the medicines that leave or return to the storage location;

[0071] S4: Provide light inside the medicine cabinet every time the medicine cabinet is opened, and delay interruption of light after the medicine cabinet is closed;

[0072] S5: When the medicine is first stored in the medicine cabinet and during the delayed interruption of illumination after the medicine cabinet is closed, images of the planned storage location of the medicine and its surrounding area are captured from above the planned storage location of the medicine, and output as a reference image and a verification image;

[0073] S6: Output the drug storage prompt based on whether the drug is stored in the planned storage location; compare the shadow area in the reference image and the verification image, and output the drug storage status based on the weight change of the drug at the storage location.

[0074] The specific steps for comparing the shadow areas in the reference image and the verification image are as follows:

[0075] Obtain the center of the medicine container when the medicine is first placed in the medicine cabinet, select several shadow edge points based on the shadow area in the reference image, calculate the distance between the center of the medicine container and each shadow edge point, and obtain the reference distance;

[0076] Obtain the center of the medicine container after the medicine cabinet is closed, select several shadow edge points based on the shadow area in the verification image, calculate the distance between the center of the medicine container and each shadow edge point, and obtain the verification distance;

[0077] The reference distance is compared with the verification distance. When the difference between the reference distance and the verification distance exceeds a threshold, the drug storage status is output as abnormal position or sealing.

[0078] Example 2

[0079] The difference from Example 1 is that the processing module 500 is used to record the frequency of each drug leaving or returning to the storage location. When the frequency of a drug leaving or returning to the storage location exceeds a threshold, the currently planned storage location of the drug is obtained and the planned storage location of the drug is adjusted. The processing module 500 is also used to output location adjustment information after the planned storage location of the drug is adjusted. The output location adjustment information can also be displayed through the human-computer interaction interface.

[0080] For example, when medicines stored on the top layer of the medicine cabinet are frequently taken and placed, when the frequency of taking and placing the medicines exceeds a threshold, the processing module 500 adjusts the planned storage location of the medicines, such as adjusting the storage location of the medicines to the middle layer of the medicine cabinet, so as to facilitate subsequent users to take and place the medicines.

[0081] The above is only an embodiment of the present invention, and common knowledge such as the specific structure and / or characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
