Segmented Spinal Decompression Bed with Adaptive Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extension bed devices for spinal decompression lack precision in applying tensile forces, are uncomfortable for patients due to belt systems, and pose difficulties in adjusting to individual body sizes and acute back pain issues, limiting effective treatment of specific intervertebral discs and vertebral joints.
Innovation Solution
The design features a bed area with multiple protruding support elements that adapt to the patient's body contour, allowing for individualized support and precise adjustment of tensile forces, eliminating the need for belts and enhancing comfort by using a system of segments and drive motors to apply targeted decompression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a belt system is used to secure the patient, then the patient can be fixed to the lying surface, but the patient experiences discomfort and painful pressure points
Solution Approach 1:
The lying surface is divided into multiple independently adjustable segments instead of using a single belt system. Each segment can be individually positioned to provide support at specific anatomical locations, distributing the securing function across multiple points rather than relying on compressive belts that cause pressure points.
Solution Approach 2:
Different segments of the lying surface are designed with different properties and adjustability to match specific anatomical regions. This allows localized adaptation to patient body contours and provides targeted support without the need for uniform belt compression across the entire body.
2Shape
If the hip support area angle is adjusted, then the lumbar spine can be brought into extension position, but the angle of force application on vertebrae cannot be precisely determined
Solution Approach 1:
The system transitions from static angle adjustments to dynamic, multi-degree-of-freedom segment positioning. Each segment can be independently adjusted in position and orientation, allowing real-time optimization of force application angles and precise control over the mechanical axis through the spinal segments being treated.
Solution Approach 2:
Multiple geometric parameters of each segment (position, orientation, angle) can be independently changed and precisely controlled, rather than relying on a single hip support angle. This enables precise determination and control of force application angles through coordinated adjustment of multiple segment parameters.
3Adaptability or versatility
If the lying surface is adjusted for different patient heights, then accommodation is possible, but only to a very limited extent
Solution Approach 1:
The lying surface is segmented into multiple independently adjustable sections, each capable of individual positioning. This segmentation allows the system to adapt to various patient heights and body proportions by configuring different segment positions, providing extensive adaptability without requiring complete redesign for each patient size.
Solution Approach 2:
The segments are designed with dynamic adjustment capabilities, allowing real-time reconfiguration of the lying surface geometry. This enables the system to accommodate different patient heights and anatomical variations through programmed or manual adjustment of segment positions and orientations.
4Force
If the lower section is moved horizontally, then spinal decompression can be achieved, but the traction force is distributed across multiple spinal segments rather than targeting a single disc
Solution Approach 1:
The lying surface is divided into multiple segments that can be independently positioned and moved. This allows the traction force to be applied at specific locations between segments, enabling targeting of individual intervertebral discs or facet joints rather than distributing force across multiple segments. Each segment's position can be configured to isolate the treatment to a specific spinal level.

AI summary
The invention relates to an extension bed device (1, 2, 36) for decompression of the spinal column (30) and/or for decompression of articulation joints of a patient (3), having a bed region (4) and having a drive system (5), wherein the bed region (4) has a plurality of segments (6), wherein the patient (3) can be arranged on the bed region (4), wherein at least one of the segments (6) can be moved by means of the drive system (5) in such a way that for decompression traction and counter-traction can be exerted on the patient (3). The effectiveness of the decompression is improved, the range of options is extended and the application of the method is more pleasant and more effective for the patient because the segments (6) have a plurality of rising support elements (7), wherein the patient (3) can be supported at least partially by the support elements (7), wherein the support elements (7) can be disposed at different heights in such a way that the arrangement of the support elements (7) can be adapted to the contour of the patient (3) in the longitudinal direction and the transverse direction, such that the patient (3) is held in an imprint formed by means of the support elements (7).
