AI Technical Summary

Technical Problem

Existing first aid kits have deficiencies in structural design, functional configuration, and ease of use, making it difficult to meet the requirements of modern emergency rescue for efficiency, accuracy, and intelligence. First aid supplies are not clearly classified, are difficult to find quickly, are poorly managed, and lack intelligent supervision.

Method used

A sorting and retrieval device was designed, including an outer box assembly, a positioning rotating frame assembly, an inner module box assembly, a pushing assembly, and a side cover. It uses a human-machine interaction module for item identification and positioning, and achieves automated retrieval and return through rotation and pushing mechanisms. It also incorporates RFID technology for intelligent management.

Benefits of technology

It enables precise definition, automated retrieval, and intelligent management of first aid supplies, improving the efficiency of item retrieval, ensuring the accuracy and safety of items, and avoiding misuse and waste.

Abstract

This invention provides a sorting and retrieval device and a first-aid kit, belonging to the field of medical equipment technology. It includes a cylindrical outer box, a positioning rotating frame, an inner modular box, a pushing assembly, and a side cover. The rotating frame is coaxially mounted within the outer box cavity and can automatically rotate at a fixed point. Multiple inner boxes are slidably connected to the rotating frame and held in a retracted state by a return spring. A pushing screw and a pushing guide rod are provided in the middle of the outer box, cooperating with the pushing frame. A side cover with elastic closure is installed in a side hole on one side of the cylindrical outer box. The location of the first-aid supplies is identified and recorded through a human-machine interface module. When selecting, the rotating frame rotates the corresponding inner box to a position directly opposite the side hole. The pushing frame overcomes the spring force of the return spring to push out the inner box and open the side cover for retrieval. After retrieval, the pushing frame resets, the inner box retracts under the action of the return spring, and the side cover automatically closes. This achieves intelligent positioning, automatic dispensing, and orderly management of first-aid supplies, offering advantages such as convenient storage and retrieval, prevention of confusion, and prevention of contamination.
