Wearable Defibrillator Carrying Case with Adjustable Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable cardioverter defibrillator (WCD) carrying cases are uncomfortable for long-term use, offer limited wearability options, and have unstable designs that can be difficult to use, especially for patients with poor hand mobility or those who need to wear the device for extended periods.
Innovation Solution
A carrying case with adjustable straps, a rubber-coated quick release coupling, and a design that allows for secure and comfortable wear on various parts of the body, including the waist and shoulder, featuring multiple fabric layers and inset connection points to prevent wobbling, along with a latching strap and pocket for easy access to the defibrillator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing WCD carrying cases are used, then the device can be carried, but they are uncomfortable for long-term use and offer limited wearability options
Solution Approach 1:
The patent applies dynamics by providing an adjustable strap system that can be configured in multiple ways (single shoulder, dual shoulder, waist, or cross-body wear). The strap length and configuration can be dynamically adjusted to suit different patient needs and wearing preferences, transforming a static carrying case into a versatile wearable device that adapts to various body types and comfort requirements for extended wear periods
2Reliability
If existing WCD carrying cases are used, then the device can be carried, but they have unstable designs that can be difficult to use, especially for patients with poor hand mobility
Solution Approach 1:
The patent implements self-service through the quick-release coupling mechanism that allows the strap to be easily attached and detached without requiring complex manual operations. The coupling design enables patients with poor hand mobility to independently adjust or remove the strap as needed, making the device self-adjusting and eliminating the need for assistance or complex fastening procedures
3Speed
If existing WCD carrying cases are used, then the device can be carried, but they are difficult to access the defibrillator quickly
Solution Approach 1:
The patent applies preliminary action by positioning the defibrillator in a readily accessible location within the carrying case, with the latching strap designed to be quickly released. The device is pre-positioned and the access mechanism is simplified so that in an emergency situation, the defibrillator can be rapidly retrieved without requiring complex操作步骤, ensuring immediate access when time is critical

AI summary
In one embodiment, a carrying case for a wearable cardioverter defibrillator (WCD) is described. The carrying case includes a container with a front wall, a rear wall, and a gusset coupling the front wall and the rear wall. The carrying case also includes each of the front wall and rear wall including multiple fabric layers. The carrying case also includes two connection points inset from an edge of the rear wall. The carrying case also includes an adjustable strap removably coupled to the connection points, the adjustable strap configured to be worn in various configurations on a body of a patient.
