Moreover, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is only for describing particular embodiments and not for limiting the invention.The term "and / or" as used herein includes any combination of one or more of the related listed items. It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from each other. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element. As shown in Figures 1 to 3, the technical solution according to the present invention is a first aid kit system, mainly including a kit body 1 and a control module. The kit body 1 is equipped with a transparent display screen 2, and the transparent display screen 2 is equipped with a touch panel module. The interior of the kit body 1 is divided into multiple compartments 3 of different sizes. The compartments 3, through a reasonable layout, are used to place various types and specifications of first aid supplies 4, such as bandages, disinfectant, adhesive bandages, first aid medicines, etc. The compartment 3 has an internal placement frame to ensure the first aid supplies 4 are placed stably within it. Simultaneously, each compartment 3 is equipped with an LED light, located at the top, which illuminates the entire compartment 3 and the first aid supplies 4, providing good lighting without hindering storage or user access. The control module includes a control motherboard, a touch panel module, an RFID reading module, and an information processing unit. The control motherboard integrates the information processing unit and interface circuits connecting to each module. The information processing unit analyzes, processes, and calculates various data to achieve the system's functions. The interface circuits connect to other modules within the control module, ensuring stable and efficient data transmission and communication. The touch panel module is closely connected to the control motherboard and serves as the primary interface for user interaction with the first aid kit system. When the user selects a type of first aid, the touch panel module presents the name, image, and brief description of the first aid supplies 4 corresponding to each compartment 3 in a clear and intuitive manner. Users can quickly learn about the types and basic information of the first aid supplies 4 in the medicine box by touching the corresponding areas on the screen. For example, if a user encounters someone with a sprained ankle in a gymnasium, they can select "bandage" from the first aid supply 4 type interface through the touch panel module. At this time, the LED light in the corresponding "bandage" grid (HK 30135833 A 5 3) will light up, allowing the user to see the bandages inside the medicine box through the transparent display screen 2. At the same time, the transparent display screen 2 displays information such as how to use the bandages and precautions. When the user selects the first aid training interface, the touch panel module will provide a simulated human body model or body part diagram. The user can drag and drop the first aid supplies 4 onto the corresponding body part through touch operation.At this time, the touch panel module transmits the user's operation signal to the control motherboard. The information processing unit in the control motherboard analyzes and processes the information according to the preset algorithm, generates and displays detailed instructions on how to use the first aid equipment 4 on the corresponding body parts through the touch panel module. The teaching content includes various forms such as text descriptions, picture displays, video demonstrations, and voice explanations to meet the learning needs of different users. For example, in a building lobby, if someone wants to learn CPR, they can drag the "dummy" and "AED (Automated External Defibrillator)" to the chest area on the first aid teaching interface of the transparent display screen 2. The transparent display screen 2 will then display detailed CPR operation steps and a video tutorial on how to use the AED. In the first aid teaching scenario, the LED lights change color and / or flashing pattern according to the instructions of the control motherboard to indicate the order of use of the first aid equipment 4. In the aforementioned CPR instruction, when an AED needs to be used first, the LED in cell 3 containing the AED flashes red, prompting the user to use the device first. When performing chest compressions, the LED in cell 3 containing the "dummy" flashes green, flashing at the correct compression frequency to guide the user. When the user selects an injury condition, the touch panel module lists various common body part injuries, such as head injuries, arm fractures, and leg abrasions. After the user selects the corresponding injury condition by touch, the touch panel module transmits the selection signal to the control board. The information processing unit in the control board analyzes and processes the information according to a preset algorithm, generating and displaying the corresponding first aid methods and necessary first aid supplies 4 on the touch panel module. It also provides relevant first aid precautions and emergency treatment steps to help the user make correct judgments and actions in emergency situations. For example, in a shopping mall, if someone cuts their arm and bleeds, they can select "cut" on the injury information interface of the transparent display screen 2, then select the injured area "arm." The transparent display screen 2 will then show that the wound should first be cleaned with disinfectant, followed by bandaging with gauze, and the corresponding LED lights in the disinfectant and gauze compartments 3 will illuminate. The RFID reading module is connected to the control motherboard and is located in each compartment 3 within the medicine box body 1. The RFID reading module uses radio frequency identification technology to quickly and accurately read the information from the RFID tags 5 on the first aid supplies 4. The RFID tags 5 are passive tags, offering advantages such as small size, low cost, and long service life. Each RFID tag 5 records a unique identification code for the first aid supply 4, as well as detailed information about the first aid supply 4, such as name, specifications, model, manufacturer, and expiration date.When first aid supplies 4 are placed into the medicine box compartment 3, the RFID reading module automatically reads the information of its RFID tag 5 and transmits this information to the information processing unit of the control motherboard for processing. For example, in a first aid medicine box placed in a stadium, when the medicine box is opened and first aid supplies 4 are placed inside, the RFID reading module quickly reads the information of the RFID tag 5 on the first aid supplies 4 inside the medicine box, such as the name and expiration date of bandages, disinfectants, etc., and displays the first aid category interface on the transparent display screen 2. Each compartment 3 displays the name, picture, and brief information of the first aid supplies 4. The information processing unit is closely connected to the RFID reading module and the touch panel module. It is the data processing center of the entire control module. After receiving the information of the first aid supplies 4 read by the RFID reading module, the information processing unit analyzes, processes, and stores this information. On the one hand, it updates the content displayed on the touch panel module according to the processing results to ensure that the user can keep abreast of the latest status of the first aid supplies 4 in the medicine box. On the other hand, the information processing unit will provide corresponding reminders based on the usage status of the first aid supplies 4. For example, when first aid supplies 4 are used, the information processing unit records their usage and determines whether replenishment is needed based on preset rules. As shown in Figure 5, the control motherboard also has a storage module. The management method includes: when the information processing unit processes information read by the RFID reader module, the usage record of first aid supplies 4 is transmitted to the storage module for storage. Furthermore, the information processing unit analyzes the results to optimize emergency response plans and manage first aid supplies 4. For example, by analyzing the usage records of first aid supplies 4 over a period of time, it is found that an office frequently uses adhesive bandages; therefore, the amount of adhesive bandages in the office's first aid kit can be appropriately increased. The alarm unit is connected to the control motherboard via a wireless communication module. The alarm unit uses advanced wireless communication technology, enabling stable and reliable wireless communication with external communication devices. When the injured person's condition is critical, the user can trigger the alarm unit via the alarm button on the touch panel module. The alarm unit will immediately send alarm information to preset medical personnel or emergency centers, including the injured person's general condition and the location of the first aid kit. Simultaneously, the alarm unit will also emit sound and light alarm signals to attract the attention of surrounding personnel and buy more rescue time. In addition, a positioning module is provided to work in conjunction with the alarm unit. This positioning module is connected to the control motherboard and employs high-precision positioning technologies such as GPS and BeiDou to obtain the real-time location information of the medicine box body 1. When the alarm unit is triggered, the positioning module transmits the location information of the medicine box body 1 to medical personnel via a wireless communication module, enabling them to quickly and accurately locate the injured person and improve rescue efficiency.As shown in Figure 4, the medication replenishment and replacement reminder unit is connected to the control mainboard. It is responsible for monitoring the usage and expiration date of the first aid supplies 4 in the medicine box. When the first aid supplies 4 are used up, resulting in a shortage or expiration, the medication replenishment and replacement reminder unit will promptly notify the person in charge to replace them. Notification methods can include various forms such as sound reminders, light reminders, SMS reminders, and email reminders to ensure that the person in charge can receive the reminder information in a timely manner and take appropriate measures. For example, in the first aid medicine box in the office, the RFID reading module rereads the information of the first aid supplies 4 every week. If it finds that a bottle of disinfectant has one week left to expire, the information processing unit will transmit this information to the transparent display screen 2 to display a reminder, and at the same time send an instruction to the medication replenishment and replacement reminder unit. The medication replenishment and replacement reminder unit will notify the office person in charge to replace it in time via SMS or email. The automatic disinfection system can be an ultraviolet disinfection device or an alcohol spray device, etc., and the automatic disinfection system is connected to the control mainboard inside the medicine box body 1. The automatic disinfection system disinfects the inside of the medicine box at preset time intervals, and can also automatically start the disinfection program after each use, effectively preventing bacterial growth and ensuring the hygiene and safety of the first aid supplies 4 in the medicine box, providing users with a clean first aid environment.As shown in Figure 3, the management method of the first aid kit system of the present invention includes the following steps: HK 30135833 A 7 Step 1: Obtain information about the first aid supplies 4 in the kit through an RFID reader, analyze and process it through an information processing unit, and transmit it to a transparent display screen 2 for displaying the first aid type interface, first aid teaching interface, and injury situation interface; Step 2: When the user selects the first aid type interface through the touch panel module of the transparent display screen 2 and selects the first aid supplies 4, the touch panel module transmits the selection signal to the control motherboard. The control motherboard controls the LED light in the corresponding first aid supply 4 compartment 3 to light up, and at the same time, the information processing unit obtains the purpose and usage information of the first aid supplies 4 and transmits it to the transparent display screen 2 for display; Step 3: When the user selects the first aid teaching interface through the touch panel module of the transparent display screen 2, the user selects the first aid supplies 4 by dragging and dropping them to the corresponding body part. The touch panel module transmits the selection signal to the control motherboard. The information processing unit in the control motherboard analyzes and processes the information according to a preset algorithm, generates and displays the usage instructions for the first aid supplies 4 on the corresponding body part through the transparent display screen 2; Step 4 ... The touch panel module selects the injury condition interface. The user selects the corresponding injury condition, and the touch panel module transmits the selection signal to the control motherboard.
