Description

Technical Field

[0001] This utility model relates to the field of first aid backpacks, and in particular to a multifunctional first aid backpack. Background Technology

[0002] First aid backpacks for teaching purposes are specialized equipment used for teaching first aid knowledge and skills. They are mostly made of wear-resistant and waterproof materials, and the interior is divided into sections according to the first aid process (such as a hemostasis and bandaging area, an immobilization and transport area, a cardiopulmonary resuscitation area, etc.). They are equipped with transparent storage bags for easy identification of items.

[0003] Simulated first aid supplies: such as reusable simulated wound modules (including different types of wound stickers / silicone models), non-elastic training tourniquets, lightweight demonstration splints, simulated disinfectant / bandages (non-medical, for teaching purposes only); Teaching tools: first aid operation flowcharts (including hemostasis, bandaging, immobilization, and CPR steps), human anatomy diagrams (marking key areas), portable first aid manuals (including theoretical points); Interactive devices: some include CPR training mannequin accessories (such as replaceable lung bags), AED training machines (simulating defibrillation operations) or Bluetooth voice guidance modules (synchronously explaining key points of operation). Features: Items are safe and risk-free (avoid sharp objects / medications), durable and easy to clean, lightweight and portable (suitable for classroom / outdoor teaching scenarios). Applicable scenarios: school first aid courses, community safety training, corporate employee emergency drills, and other teaching activities.

[0004] Currently, first aid backpacks generally lack specialized puncture-proof storage designs for sharp medical instruments. They are mostly ordinary cloth bags or mesh bags, which easily lead to exposed needles, scalpels, and other sharp points. This can puncture other items inside the bag (such as dressings and medicine packaging), causing contamination or damage, and can also easily cut the user when retrieving or organizing them, posing a safety hazard. In terms of compartmentalized storage, most backpacks use fixed large spaces or a limited number of simple dividers, which cannot be flexibly adjusted according to the size of the instruments (such as different sizes of needles and scissors). This results in sharp instruments being mixed with other items (such as gauze and disinfectant), leading to chaotic classification, time-consuming searches in emergencies, and small items easily scattering, increasing the risk of cross-contamination and affecting the efficiency of emergency care. Utility Model Content

[0005] The main objective of this invention is to provide a multifunctional first aid backpack that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-functional first aid backpack includes a backpack body, a front pocket, a first chain fabric, a second chain fabric, a handle, backpack straps, and side pockets. The front pocket and backpack straps are located at the front and rear ends of the backpack body, the second chain fabric is located at the upper opening of the front pocket, the first chain fabric is located at the upper opening of the backpack body, and the handle and side pockets are located at the upper end and side wall of the backpack body, respectively. The backpack body has a bottom protective layer at the bottom and a top protective layer at the top. The opening of the bottom protective layer is provided with elastic cloth and waterproof isolation cloth, which divides the inner cavity of the backpack into a bottom cavity and a top cavity, so as to realize the separate storage of the first aid backpack. The bottom cavity contains a first aid kit, which contains first aid medical equipment. The top cavity contains a teaching anatomical model for first aid instruction.

[0007] In an optional embodiment of this application, the handle, front pocket, side pocket and backpack strap are connected to the backpack body by needle and thread sewing. The front pocket and the upper opening of the backpack body are provided with zippers. The first chain fabric and the second chain fabric are connected to the backpack body by needle and thread sewing for covering the zippers of the front pocket and the backpack body. In an optional embodiment of this application, the bottom protective layer and the top protective layer have a "U" shaped cross-section. The bottom protective layer and the top protective layer are connected to the backpack body by needle and thread. The thickness of the top protective layer is half the thickness of the bottom protective layer. The top protective layer and the bottom protective layer include a waterproof cover and memory foam, with the memory foam placed in the inner cavity of the waterproof cover. In an optional embodiment of this application, the elastic fabric and the waterproof isolation fabric are sewn together with needle and thread, the waterproof isolation fabric has pleats that expand with the elastic fabric, and the waterproof isolation fabric and the bottom protective layer are connected by needle and thread sewing or zipper. In an optional embodiment of this application, the sidewall of the bottom protective layer is provided with an elastic pull rope and a rope loop.
