Self-wrapping restraint device for rapid patient immobilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current physical restraint devices for healthcare settings are inefficient in rapid and effective immobilization, often causing instability and excessive effort for caregivers, potentially leading to harm to patients and operators.
Innovation Solution
A self-wrapping safety device with a main body and self-wrapping strips that move from a coplanar first position to a wrapped second position, facilitated by activation handles and cables, ensuring rapid and secure immobilization without causing accidental harm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional restraint devices with Velcro bands are used, then the device can wrap around the patient's body, but the wrapping process is slow and does not allow rapid immobilization
Solution Approach 1:
The device transitions from a static coplanar configuration to a dynamic wrapped configuration around the patient's body. The main body and self-wrapping strip are designed to move from a first coplanar position to a second wrapped position, enabling rapid transformation and immobilization through dynamic structural change rather than gradual wrapping.
Solution Approach 2:
The restraint device is divided into a main body and a separate self-wrapping strip, both capable of independent movement and wrapping. This segmentation allows the strip to wrap around the patient's body independently while the main body provides structural support, enabling faster immobilization compared to a single-piece design.
2Reliability
If traditional restraint devices are used, then the patient can be restrained, but postural stability is not guaranteed risking physical harm
Solution Approach 1:
The device adapts its configuration dynamically to match the patient's body shape and posture. By wrapping around the patient's body in the second position, the device provides conformal contact that stabilizes the patient's posture and prevents harmful movements, thereby improving both reliability and postural stability simultaneously.
3Productivity
If traditional restraint devices are used, then the patient can be immobilized, but excessive effort is required by care operators
Solution Approach 1:
The self-wrapping strip automatically wraps around the patient's body when the device is applied, reducing the manual effort required by care operators. The strip's self-wrapping mechanism performs the immobilization action autonomously once initiated, minimizing the force and effort needed by operators while maintaining effective immobilization.
4Ease of manufacture
If traditional restraint devices with Velcro bands are used, then the device can be made simple, but they may cause direct or indirect harm to the patient due to pressure exerted on the body
Solution Approach 1:
The self-wrapping strip is designed as a flexible element that conforms to the patient's body contours, distributing pressure evenly across the contact surface. This flexible design maintains simplicity in manufacturing while eliminating concentrated pressure points that could cause harm to the patient.
