Inclined Armrest for CT Scan Patient Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing armrests for examination beds are not anatomically adapted, causing patient discomfort and accessibility issues for medical professionals, particularly during procedures like fluoroscopy and CT scans, as they often require the patient's arms to be bent, which complicates infusion and cannula management and restricts movement within limited spaces.
Innovation Solution
An armrest design featuring a flat base plate that can be slid under the examination table with an inclined support plate, allowing the arm to be positioned naturally and comfortably, adjustable to fit various body sizes, and incorporating a channel-shaped support part that can be fixed securely using straps, ensuring stability and accessibility without protruding laterally, thus accommodating the anatomical needs and movement requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the armrest is designed with a parallel support plate to the bed, then the structure is simple and stable, but the patient's arm must be bent which causes discomfort and accessibility issues
Solution Approach 1:
The support plate is designed with an inclined angle (10°-30°) relative to the base plate, creating a dynamic anatomical alignment that allows the patient's arm to rest in a natural, relaxed position rather than being forced into a bent position. This angular adjustment optimizes both comfort and medical accessibility.
Solution Approach 2:
The inclined angle parameter of the support plate is specifically adjusted to match anatomical requirements, transforming the parallel configuration into an angled configuration that accommodates the natural arm position while maintaining structural simplicity.
2Adaptability or versatility
If the armrest support plate is fixed in position, then the structure is stable, but it cannot accommodate different body sizes and anatomical variations
Solution Approach 1:
The armrest assembly allows the support plate to be adjusted to different positions and angles, enabling adaptation to various body sizes and anatomical variations while maintaining stability during use through secure fixing mechanisms.
Solution Approach 2:
The armrest is designed with adjustable features that allow it to serve multiple patients with different body types and anatomical requirements, making it a universal solution rather than a fixed-size device.
3Ease of operation
If the armrest protrudes laterally to provide accessibility, then doctors can access the arms easily, but it interferes with movement in limited spaces like CT tunnels
Solution Approach 1:
Instead of providing accessibility through lateral protrusion, the inclined support plate creates accessibility in a different dimensional orientation, allowing the arm to be naturally accessible while maintaining a compact lateral profile suitable for confined spaces like CT tunnels.
4Ease of manufacture
If the arm is positioned in a bent position on traditional armrests, then the armrest structure is simple, but it complicates infusion and cannula management
Solution Approach 1:
The inclined support plate creates a dynamic anatomical alignment that naturally positions the arm for both comfort and medical accessibility, eliminating the need for complex bent-position accommodations while simplifying both structure and medical procedures.

AI summary
The invention relates to an arm rest for positioning the arm of a patient in relation to an examination table, especially during a tomographic radioscopy examination or an operation. Said arm rest comprises an essentially flat base plate (1) that can be pushed under the body of the patient or beneath the mattress of the examination table, a supporting plate (2) which is inclined in relation to the base plate (1) or arranged at an angle thereto, and a long carrier element (3) which is arranged on the end of the supporting plate (2), at a distance from the base plate (1), and is longer (9) and narrower (8). According to the invention, the carrier part (3) is inclined in terms of the longitudinal dimension (9) thereof in relation to the base plate (1).
