Device for structured action guidance in medical emergencies, consisting of a modular emergency information system with graphically simplified action algorithms and a corresponding reference bookmark.

Abstract

Emergency information system to support first responders, characterized by the fact that medical procedures are represented in a graphically reduced symbolic system, whereby the representation is abstracted to essential, action-relevant features ("pictogram system") in order to minimize cognitive load in stressful situations.

Description

1. Technical environment and problem statement

[0001] The invention relates to a device for supporting first responders (laypersons, company first aiders, school first aid teams) in medical emergencies. In highly stressful situations, human reliability tends to be compromised by cognitive overload. Conventional manuals and folders / booklets are often text-heavy, time-consuming to search for information, and do not offer a clear structure for different qualification levels. 2. Solution to the technical problem

[0002] The device according to the invention solves this problem through a combination of haptic navigation, didactic reduction, and modular information separation. The aim is a "backup brain" that ensures the error-free execution of life-saving measures under time pressure. 3. Structure and functions of the device A. Two-dimensional haptic navigation (staircase indexing) The device features a staircase indexing system located on two sides (preferably on the right and bottom edges). This arrangement allows immediate access to a total of 11 specific emergency categories without time-consuming page-flipping. The haptic guidance directs the user straight from the initial assessment to the specific action guide. B. Modular information level (layperson-professional separation) A key feature is the spatial separation of the content on the open pages: • Right side: Representation of linear action algorithms in a graphically highly reduced system (pictograms) and imperative language for immediate intervention. • Left side: Supplementary clinical scores, vital parameters and measurements (e.g. GCS, shock index, qSOFA score) to objectify the condition for advanced first responders and to optimize the handover to the emergency medical service. C. Visual Guidance and Color System The device uses a consistent color logic (traffic light system) to prioritize actions. A central flowchart on the title page (xABCDE scheme) serves as the mandatory entry point. The colored arrows (e.g., red and white stripes for identifiable disruptions) intuitively guide the user to the necessary course correction. D. Anatomically Sequential Trauma Module (5B Scheme) To identify concealed bleeding sources, the device integrates a specific module that guides the user through the sequence "pear, chest, abdomen, pelvis, legs". This graphic and textual sequence ensures that critical bleeding is sought in the anatomically correct priority. E. Corresponding Reference Bookmark An external hardware component, a bookmark, serves as a permanent visual anchor. It contains an integrated universal algorithm embedded in CRM (Crew Resource Management), an anamnesis tool (acronym "COLLECT"), and reference values ​​for vital parameters. It can be viewed while browsing the file, but can also be used directly on the injured person to visually recall the sequence of actions at any time. 4. Advantages of the invention

[0003] The device minimizes search times and the cognitive load on the user. The "10-for-10 principle" (10-second pause for orientation) combined with the graphical "four-line system" significantly reduces the error rate in first aid. It serves as an interface tool, enabling professional data transfer between first responders and emergency medical services. 5. Commercial applicability and industrial exploitation

[0004] The device is intended for serial production and use in professional emergency environments and for use by laypersons as workplace first aiders. Commercial use includes, in particular: • The equipment of company first aiders in accordance with DGUV regulations. • Its use in educational institutions (schools) - e.g. in school first aid services - as a standardized teaching aid. • Integration into emergency equipment (e.g., emergency folders, first aid kits, AED stations) as an accompanying process control system. Due to its modular design, the system is infinitely scalable and adaptable to various medical fields (e.g., workplace first aid – including industry-specific first aid, company medical services, daycare centers, outdoor medicine).
