Patient Arm Restraint Using Body Weight for Immobilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arm restraints in medical settings fail to securely immobilize arms in a supine position without applying excessive force, posing a risk of injury or interference with medical devices.
Innovation Solution
A flexible, washable fabric apparatus with a sleeve portion for each arm, a transverse portion under the torso for immobilization, and adjustable straps that secure to the body and hospital bed rails, utilizing the patient's weight for immobilization and allowing for easy access to medical devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional straps and panels are used to restrain arms, then arms can be secured, but the restraint cannot firmly immobilize arms in a supine position without applying excessive force
Solution Approach 1:
The restraint device is divided into multiple functional components: a base panel for support, sleeve portions for arm coverage, and transverse portions for securing under the torso. This segmentation allows each component to perform its specific function optimally, with the transverse portions specifically designed to utilize body weight for immobilization without excessive force.
Solution Approach 2:
The restraint device utilizes the patient's own body weight as the immobilizing force through the transverse portions that extend under the torso. This self-service mechanism eliminates the need for external locking mechanisms or excessive applied force, as the patient's weight itself provides the necessary restraint pressure.
2Reliability
If arms are restrained firmly to prevent device removal, then medical devices are protected, but access to medical devices during procedures becomes difficult
Solution Approach 1:
The restraint device incorporates dynamic elements including adjustable straps and Velcro® fasteners that allow the restraint to be easily adjusted or temporarily released during medical procedures. This dynamic design maintains device protection during normal conditions while enabling quick access when needed.
Solution Approach 2:
The restraint device acts as an intermediary layer between the patient's arms and the medical devices, providing protection while maintaining accessibility. The design allows caregivers to access devices through the restrained arms without compromising the restraint's protective function.
3Reliability
If restrictive restraints are used to prevent voluntary or involuntary arm movement, then medical equipment is protected, but patient comfort and safety are compromised
Solution Approach 1:
The restraint device uses a flexible fabric base panel and soft strap construction that conforms to the patient's body contours. This flexibility allows the restraint to provide firm immobilization for equipment protection while avoiding excessive pressure points that could cause patient injury or discomfort.
Solution Approach 2:
The restraint device allows for adjustable parameters including strap tightness and positioning that can be modified based on patient needs. This adjustability enables optimization of the balance between equipment protection and patient comfort/safety for each individual case.
