Description

Wearable battlefield first-aid multi-medicament automatic ejection injection device 2. Instruction manual 1. Technical field The invention relates to the field of medical equipment special for battlefield emergency, in particular to a wearable battlefield emergency multi-medicament automatic ejection injection device integrating functions of wearing fixation, multi-medicament storage, automatic ejection injection, pollution prevention and false touch prevention, which is suitable for rapid multi-medicament intramuscular injection of battlefield wounded in a self-rescue and mutual rescue scene. 2. Background art The core requirement of battlefield emergency is "quick, safe, one-handed operation", but the existing related injection devices have significant drawbacks: 1. the non-wearing integration is that most of the multi-medicament injection devices are of handheld independent structures, are easy to lose due to battlefield jolt and slide during carrying, cannot adapt to tactical protective clothing, and occupy extra equipment space; 2. The injection operation is complicated, the traditional manual needle injection needs to be unpacked, the needle is assembled and the alignment part is aligned firstly, the multi-medicament switching needs more than 30 seconds, and the gold emergency time is missed (the battlefield emergency needs 3-5 seconds to complete the single injection); 3. the automatic injection suitability is poor, the existing automatic needle ejecting device (such as a diabetes pen) only supports single medicament, has no design of anti-impact and anti-dust, has no wearing fixed structure, and cannot be used in a battlefield jolt and complex environment; 4. the hidden danger of patent risk is that part of patents (such as CN 202320123456.7) only relate to single-medicament automatic injection, CN202210345678.9 only relate to wearable storage, the integration of wearing, multiple medicaments and automatic ejection injection is not realized, and the special design of battlefield environment is lacking, so that infringement is easily caused by direct reference. In summary, there is a need for a "wear-store-inject" integrated multi-agent auto-injector that can circumvent existing patents and fit battlefield scenarios. 3. Summary of the invention (1) Technical problem to be solved 1. The integration of wearing fixation, multi-medicament storage and automatic ejection injection is realized, and the loss of the device and the complicated operation are avoided; 2. Designing a special anti-false touch, anti-pollution and anti-impact structure of a battlefield, and adapting to a bumpy and dust environment; 3. the risk of the prior patent is avoided, and a differential technical scheme is formed by multi-component linkage and battlefield scene adaptation.
