Multi-function emergency bandage

Abstract

A unique multi-functional emergency bandage is introduced, wherein bleeding is stopped by: (1) optimizing mechanical properties and preventing ischemia and / or necrosis while applying enough pressure to help stop bleeding, and (2) incorporating inorganic anti-bleeding nano-structures (embedded within a gauze and / or microbial cellulose) with almost infinite life-time. Additionally, pathogen passage through the bandage is prohibited (via an intermediate filter layer). Together with the overall anti- microbial character of the bandage, the unique multi-functional bandage offers all these vital features within a single design. The unique bandage can be applied by using a single hand and bandaging direction can be changed using a unique binding apparatus. Visual aids, such as printed rectangles, on the final fabric provides the user with an indication of how to control the amount of stretch, as vertical rectangles would turn into horizontal rectangles when stretched too much, whereas rectangles turn to squares around the optimum region of the stress-strain curve.

Description

technical field [0001] The present invention relates generally to the field of medical bandages. More specifically, the present invention relates to pre-hospital emergency situations such as civilian conditions, disasters, conflict zones, war and other military applications for uncontrolled bleeding while preventing ischemia, inflammation, necrosis, pathogens and toxic substrates through bandages. application) under the unique multifunctional bandage. Background technique [0002] Currently, there are a variety of bandages commercially available for use in prehospital and hospital emergencies as first aid devices to stop bleeding from crush wounds due to blood loss, amputation, or traumatic injury. In recent years, 58% of trauma-related deaths in war have been due to extremity (e.g. arms, legs, head) injuries as reported by the U.S. Army on March 19, 2003-May 18, 2004 As reported in "WIAwoundedareas". Accordingly, applicants in the art will understand that a bandage (in a...

AI Technical Summary

Problems solved by technology

[0004] 1. Prior art bandages cannot optimize the physical properties of the bandage fabric structure by means of a stress-strain curve, and due to the lack of such optimization, most bandages on the market either fail to stop bleeding or fail when they do. pressure causing ischemia and / or necrosis;

[0005] 2. Prior art bandages are generally impractical due to the fact that most of the bandages currently on the market are formed from loose pieces, requiring such loose pieces to be used by a single user utilizing his / her hands or by two users assembled together;

[0006] 3. The prior art bandages lack mechanisms to provide biological protection of the wound from the environment, as there are no first aid bandages available in the market today that can properly isolate the wound from various pathogens, such as microorganisms and / or viruses;

[0007] 4. The prior art bandages also lack an optimal mechanism to help stop bleeding as most bandages on the market today do not employ a mechanism to promote blood clotting as such prior art bandages stop bleeding simply by applying pressure, as The aforementioned in item (1) is problematic; even in the few cases with mechanisms that promote blood clotting, such mechanisms are limited to organic matter, a contributing factor that limits the useful life of such bandages

[0008] 5. Prior art bandages lack an elastic fixation strip around the wound dressing, making it difficult for one-handed wrapping, making it critical in this field

[0009] 6. Prior art bandages cannot optimize and unify all three functions in a single design, such as i) optimizing physical properties by means of stress-strain curves and anti-slip strips ii) adding antimicrobial chemistry, iii) combining Pathogen and deleterious substrate deterrence / trapping and biological properties of facilitators of hemostasis
