Viscoelastic Table Pad for Stable Trendelenburg Patient Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During medical procedures, patients in the Trendelenburg position often experience unwanted movement and pressure-related injuries due to inadequate support on inclined operating tables, which can disrupt surgeries and cause discomfort.
Innovation Solution
A viscoelastic foam pad with specific properties, including a coefficient of static friction greater than 0.2 and a thickness of 0.75 to 1.5 inches, is used to secure patients on the table, minimizing movement and pressure points by conforming to the body and providing sufficient cushioning and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a patient is placed in the Trendelenburg position on an inclined operating table, then surgical access to the lower body is improved, but the patient experiences unwanted movement and pressure-related injuries
Solution Approach 1:
A viscoelastic foam pad is introduced as an intermediary between the patient and the inclined operating table. The pad conforms to the patient's body contours and provides a stable interface that prevents unwanted movement while maintaining the Trendelenburg position for surgical access.
Solution Approach 2:
The foam pad's viscoelastic properties are specifically selected with a coefficient of static friction greater than 0.2 and optimized thickness (0.75 to 1.5 inches) to provide sufficient friction and cushioning. These parameter changes ensure the patient remains stable on the inclined table without pressure-related injuries.
2Ease of operation
If the operating table is inclined for Trendelenburg position, then surgical procedures on lower body are facilitated, but pressure points form on the patient's body
Solution Approach 1:
The foam pad provides locally adapted support by conforming to the patient's body contours. Different regions of the pad offer customized cushioning and pressure distribution tailored to the specific anatomical features of the patient, preventing pressure points while maintaining surgical positioning.
Solution Approach 2:
The use of viscoelastic foam combines the properties of viscosity and elasticity in a single material. This composite material特性 allows the pad to both cushion pressure points and provide friction-based stability, addressing multiple harmful effects simultaneously.
3Ease of operation
If standard padding is used on the operating table, then patient comfort is improved, but patient movement is not adequately controlled
Solution Approach 1:
The foam pad's coefficient of static friction is specifically engineered to be greater than 0.2, and its thickness is optimized between 0.75 to 1.5 inches. These parameter changes provide both comfort through cushioning and stability through increased friction, unlike standard padding that lacks these specific properties.
Solution Approach 2:
The viscoelastic foam combines viscous damping with elastic recovery properties. This composite material behavior provides both comfort (through pressure distribution) and stability (through friction and conformability), addressing both requirements simultaneously.

Function Achieved in This Case
The viscoelastic foam pad effectively reduces patient movement and pressure-related injuries, ensuring stable positioning and comfort during procedures, even in steep Trendelenburg positions, by maintaining a secure hold and distributing pressure evenly.

AI summary
A method of securing a patient onto an operating table when the patient is in the Trendelenburg position and apparatus therefor including a kit. A viscoelastic pad is used to support and hold a patient on a medical procedure table during a medical procedure performed while the table, and thus the patient lying thereon, is in an inclined position, such as the Trendelenburg position. The viscoelastic pad has characteristics which promote a minimization of pressure forces on the patient's body, as well as promote a secure cushioning and holding of the patient in a desired position on the table, in order to minimize injury to the patient.
