Description

Technical Field

[0001] The present invention relates to the field of medicine management, and in particular to a medicine inventory counting device and method. Background Art

[0002] In the medical system, due to the huge amount of medicines used and their impact on human health, precise batch management is required. Currently, medicine management is generally done manually in combination with databases to manage the entry, inventory, and delivery of medicines.

[0003] However, the existing drug management method cannot automatically enter the drug information and storage location of a drug into the database. It is necessary to manually check the storage location of the drug after the drug is put into the warehouse and then record it. This is very time-consuming, inefficient, and easy to make mistakes when handling large quantities of drugs.

[0004] The prior art discloses a method and device for intelligent positioning of medicines combining infrared and RFID, the method comprising: placing medicines with RFID electronic tags and capable of reflecting infrared rays into a medicine rack; moving a mobile workbench provided with an infrared sensor and an RFID reader-writer along the medicine rack, detecting and recording the position of the mobile workbench; when the mobile workbench reaches a medicine storage position, the infrared sensor detects whether there is medicine at the position according to whether there is a reflection signal outside the red line, and if there is medicine, the RFID reader-writer reads the coding information and medicine information in the RFID electronic tag of the medicine, and stores the coding information, medicine information and the position of the medicine storage position in a corresponding relationship in a database; repeating the previous step until the mobile workbench has moved through every medicine storage position on the medicine rack.

[0005] The above structure can realize the management of medicines, but if it is only necessary to confirm whether the medicine bottle in the medicine storage box is the designated medicine, the above structure is too complicated and the cost of the device is relatively high. For example, the medicine box on the ambulance only contains one type of medicine. In this case, it is only necessary to confirm whether the medicine box contains the designated medicine, which is related to the life safety of the patient who needs rescue. In addition, the existing technology requires mobile reading of medicine information, which is slow. Summary of the invention

[0006] In order to solve the above problems, the primary purpose of the present invention is to provide an RFID-based medicine inventory device with a simple structure and capable of quickly taking inventory of medicines.

[0007] Another object of the present invention is to provide a drug inventory device based on RFID, which has low cost, good effect and is easy to promote widely.

[0008] Another object of the present invention is to provide an RFID-based medicine inventory method that can inventory medicines simply, quickly and accurately.

[0009] To achieve the above-mentioned purpose, the present invention provides a drug inventory device based on RFID, which includes a shielding box, a medicine box and an RFID reader, wherein the medicine box and the RFID reader are both placed in the shielding box, and a medicine placement position for placing medicines with RFID tags is provided in the medicine box. In the present invention, the shielding box is used to shield the reading signal of the RFID reader, so that the RFID reader can only read the RFID tag information on the medicines in the shielding box, and when multiple shielding boxes are used side by side, the RFID reader will not read the RFID tag signals of medicines in other shielding boxes. After the RFID reader reads the RFID tag information on the medicines in the shielding box, it can be transmitted to the system by wire or wirelessly. The system determines whether the medicines in the medicine box are correct according to the pre-set comparison, thereby avoiding irreparable errors caused by misplacing the medicines, and at the same time, it can also determine whether the quantity of medicines is correct, thereby determining whether the medicine box is full of medicines. Through the above-mentioned simple structural setting, the medicines can be quickly inventoried, thereby better adapting to some emergency situations.

[0010] Furthermore, the shielding box includes a bottom plate and a side plate, and the bottom plate and the side plate are connected and combined to form a groove-shaped structure with an upper end opening, and the medicine box is detachably arranged in the shielding box through the upper end opening of the shielding box. The shielding box is arranged as a groove-shaped structure with an upper end opening, and the medicine box is detachably arranged in the shielding box, which can facilitate the replacement, maintenance and inspection of the medicine box, and also facilitate the arrangement of other structures in the shielding box, and facilitate the replacement, maintenance and inspection of other structures in the shielding box. The bottom plate and side plates of the shielding box can prevent the RFID reader from sending a read signal downward or to the side, ensuring that the RFID reader can only read the RFID tag signal of the medicine in the medicine box upward, further ensuring the reading accuracy and reading speed, and effectively resisting the interference of the surrounding internal and external signals.

[0011] Furthermore, the RFID reader is clamped between the shielding box and the medicine box. The RFID reader is clamped between the shielding box and the medicine box, which allows the RFID reader to get closer to the medicine box and read the RFID tag of the medicine in the medicine box; at the same time, the RFID reader is clamped by the shielding box and the medicine box to ensure the stability of the RFID reader, and can still ensure the long-term stable operation of the RFID reader in a complex environment. For example, when the device is used in an ambulance, when the ambulance passes through a bumpy road, the above structure can well ensure the long-term stable operation of the RFID reader.

[0012] Furthermore, the RFID reader is located at the bottom of the medicine box. Preferably, the RFID reader is located between the bottom of the medicine box and the bottom plate of the shielding box. Such a structural setting can facilitate the fixation of the RFID reader. The RFID reader can be pressed directly by the weight of the medicine box itself without the need to set up other additional fixing structures. On the basis of a simple structure, a better fixing effect is achieved.

[0013] Furthermore, the bottom plate is provided with a through hole for the wire to pass through, and the RFID reader corresponds to the position of the through hole. The through hole can facilitate the wire to pass through and be electrically connected to the RFID reader, and facilitate the transmission of data from the RFID reader to the system, which determines whether the medicine in the medicine box is correct, thereby avoiding irreparable mistakes caused by misplacing the medicine, and can also determine whether the quantity of medicine is correct, thereby determining whether the medicine box is full of medicine.

[0014] Further, the medicine box includes a medicine box body, and one or more medicine placement positions are arranged on the upper side of the medicine box body, and the medicine placement positions are placement grooves arranged obliquely on the medicine box body. The medicine placement positions are placement grooves, which are convenient for placing various types of medicines, especially medicines in medicine bottles. The placement grooves are arranged obliquely on the medicine box body, which can facilitate the removal of medicines.

[0015] The present invention also provides a drug inventory method based on RFID, which is characterized by comprising the following steps:

[0016] Step 1: Attach an RFID tag containing drug information to the drug and put it into the medicine box;

[0017] Step 2: Enter the drug information in the medicine box into the system and put the medicine box into the corresponding shielding box;

[0018] Step 3: Use an RFID reader to read the RFID tag of the medicine in the medicine box, and compare the obtained medicine information with the medicine information entered into the system. If they are the same, proceed to step 4; if they are different, proceed to step 5;

[0019] Step 4: The system prompts that the information is correct;

[0020] Step 5: The system prompts an error message.

[0021] Furthermore, when the drugs are placed in the medicine box, the same drugs are placed in the same medicine box. Placing the same drugs in the same medicine box facilitates the inventory of the drugs, can significantly reduce the workload of the system comparison calculation, and is more in line with the design concept of simplicity, accuracy, and speed. Preferably, only one medicine box is placed in each shielding box, and each shielding box has an RFID reader, so that the RFID reader corresponds to the medicine box one by one, which can further ensure the accuracy of the judgment.

[0022] Furthermore, the drug information includes drug type information and quantity information. The drug type information is mainly used to confirm whether the placed drugs are wrong, and the quantity information is mainly used to confirm whether the quantity of drugs meets the use requirements, such as whether the medicine box is full and whether the quantity of drugs in the medicine box is enough for a certain use scenario.

[0023] Furthermore, in step 2, the specific steps of entering the drug information into the system are: affixing a code on the drug placement position in the medicine box, pre-reading the RFID tag affixed to the drug with an RFID reader before placing the medicine box into the shielding box, defining the order of the codes according to the order of reading, and binding the read drug information with the corresponding code in the system. The purpose of this step is mainly to encode each drug placement position, thereby distinguishing the drug placement positions; preferably, the order distinction between the drug placement positions can be achieved, and while the drugs are counted in the subsequent steps, it is convenient to locate and determine the order of drug placement, which solves the problem that the RFID tag in the prior art cannot locate the specific position and cannot determine the order of drug placement.

[0024] Furthermore, the format of RFID tags includes two formats: TID code and data code. The TID code is built into the tag when it leaves the factory, cannot be changed and is unique, and the data code can be written and rewritten. When it is necessary to conduct a quantity inventory, according to the needs of the inventory, choose to read the TID code and data code. If you choose to read the data code, the same RFID tag can be read countless times. If you choose to read the TID code, it will only be read once and will not be read again, which can prevent repeated inventory.

[0025] Furthermore, in order to avoid the problem of repeated statistics caused by the same RFID tag being read multiple times, the present invention also sets an algorithm to prevent repeated statistics. During inventory counting, the same RFID tag can only be counted once within a specified time. Once the information is completely repeated, the new counted data is automatically ignored. This can further ensure the accuracy of inventory counting.

[0026] The beneficial effect of the present invention is that, compared with the prior art, in the present invention, the shielding box is used to shield the reading signal of the RFID reader, so that the RFID reader can only read the RFID tag information on the medicines in the shielding box. When multiple shielding boxes are used side by side, the RFID reader will not read the RFID tag signals of the medicines in other shielding boxes. After the RFID reader reads the RFID tag information on the medicines in the shielding box, it can be transmitted to the system by wired or wireless means. The system determines whether the medicines in the medicine box are correct based on the pre-set comparison, thereby avoiding irreparable errors caused by misplacing the medicines. At the same time, it can also determine whether the quantity of medicines is correct, thereby determining whether the medicine box is full of medicines. Through the above simple structural setting, the medicines can be quickly counted, thereby better adapting to some emergency situations.

[0027] In addition, through the drug inventory method of the present invention, drugs can be simply, quickly and accurately inventoried to ensure that the types and quantities of drugs meet the requirements for use. BRIEF DESCRIPTION OF THE DRAWINGS
