Surgical Positioning Pad with Anti-Slip Support Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current positioning systems for surgical tables lack effective solutions to securely position patients in Trendelenburg, reverse Trendelenburg, or lateral tilt positions during surgical procedures, often resulting in patient slippage due to inadequate support and friction.
Innovation Solution
A positioning system comprising a pad body with adjustable straps and a support strip featuring anti-slip tape or textured surfaces, designed to engage with the patient's waist and arms, providing secure attachment to the surgical table through hook and loop fasteners and buckles, thereby preventing slippage across various surgical positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional positioning systems are used on surgical tables, then the system is simple in structure, but patient slippage occurs due to inadequate support and friction
Solution Approach 1:
The positioning system is divided into multiple functional components: a pad body for patient contact, multiple straps (waist strap, arm straps, leg straps) for different body regions, and a support strip with anti-slip tape. Each component addresses specific positioning needs, allowing the system to securely position patients in complex surgical positions like Trendelenburg without requiring a completely redesign of the entire system.
Solution Approach 2:
The support strip incorporates anti-slip tape with a textured or patterned surface layer that provides enhanced friction. The pad body uses foam material for comfort and pressure distribution. This composite approach combines materials with different properties (foam for comfort, anti-slip tape for friction, straps for constraint) to achieve reliable patient positioning without excessive complexity.
2Reliability
If the positioning system uses simple straps and pads, then the device is easy to operate, but it cannot provide adequate friction and weight distribution to prevent slippage
Solution Approach 1:
The positioning system applies different properties to different body regions: the waist strap provides strong constraint at the torso, arm straps secure the upper extremities, leg straps position the lower body, and the support strip with anti-slip tape provides friction at the back contact area. This localized approach ensures adequate friction and weight distribution across critical areas without requiring complex mechanisms throughout the entire system.
Solution Approach 2:
The pad body and support strip are pre-configured with straps and anti-slip surfaces before patient application. The foam pad provides immediate comfort and pressure distribution, while the pre-attached straps are ready for rapid adjustment and securing. This preliminary preparation reduces setup time and complexity during actual patient positioning.
3Reliability
If the system uses multiple straps and fasteners to secure patients, then patient positioning reliability improves, but the device complexity and setup time increase
Solution Approach 1:
The positioning system uses standardized buckles and strap mechanisms that can be applied to multiple body regions (waist, arms, legs) using the same fastening principle. This multi-functionality allows rapid adjustment and securing across different anatomical areas without requiring different types of fasteners for each location, reducing overall setup time while maintaining reliable positioning accuracy.
