Modular Patient Positioning Base With Removable Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient positioning devices for operating tables suffer from limited versatility, compromised patient comfort, inadequate restraint, and are often costly and difficult to manufacture, with foam pads posing risks of tearing and causing rashes due to high friction.
Innovation Solution
A patient positioning device with a base and removable supports, featuring bendable portions, metal supports, and Velcro-compatible materials for secure attachment to the table, allowing for customizable patient positioning and restraint, accommodating various patient sizes and positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If foam pads are used to support and restrain patients, then patient comfort is improved, but the foam pads risk tearing and causing rashes due to high friction
Solution Approach 1:
The positioning device is divided into multiple independent components: a base layer, removable supports, and restraint systems. This segmentation allows each component to perform its specific function optimally without the limitations of single-material foam pads, eliminating tearing risks while maintaining comfort.
Solution Approach 2:
The device combines multiple materials with complementary properties: the base uses materials with appropriate friction characteristics, supports use structured materials for durability, and restraint elements use specialized materials. This composite approach resolves the contradiction between comfort and durability by assigning different material functions to different components.
2Adaptability or versatility
If prior art patient positioning devices are used, then patient support is provided, but versatility is limited and manufacturing is costly and difficult
Solution Approach 1:
The base is designed as a universal platform that can accommodate multiple types of removable supports (head supports, arm supports, leg supports, etc.). This multi-functional design allows a single base to serve various positioning needs, increasing versatility while simplifying manufacturing compared to custom-designed devices for each position.
Solution Approach 2:
The device incorporates adjustable and reconfigurable elements, including removable supports that can be attached and detached, and bendable portions that can be positioned in multiple configurations. This dynamic design enables adaptation to different patient sizes and surgical positions without requiring multiple specialized devices, reducing manufacturing complexity.
3Adaptability or versatility
If removable supports are added to the base, then patient positioning versatility is improved, but device complexity increases
Solution Approach 1:
The device separates the base from the supports, allowing supports to be independently attached and removed. This segmentation reduces overall device complexity by enabling modular assembly rather than requiring a single complex integrated structure, while still providing positioning versatility through component selection.

AI summary
A patient positioning device attachable to a medical table comprising a base configured to overlie the table and underlie the patient, wherein the upper surface of the base faces the patient and the lower surface faces the table. One or more supports are removably attachable to the base to support a body region of the patient. The base can be composed of a foam material with a Velcro compatible material for removable attachment of the supports. Various shapes, sizes and function of the supports can be used.
