Patient Barrier With Pivoting Support For Imaging Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During medical imaging, unstable patient positioning leads to artifacts in radiographic images, as the subject may not be adequately supported or aligned with the energy receptor.
Innovation Solution
A patient barrier system with a footstep, frame, pivots, and support bars is designed to stabilize the patient, allowing for adjustable positioning and separation from the energy receptor, facilitating stable imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the patient is not adequately supported or positioned during imaging, then the imaging process is simpler and faster to set up, but artifacts are generated in the radiographic image due to unstable positioning
Solution Approach 1:
The positioning system is divided into separate functional components: a footstep for lower body support, support bars for arm positioning, and a frame structure for overall stability. Each component can be independently adjusted and positioned to address specific positioning needs without requiring a completely complex integrated system.
Solution Approach 2:
The patient barrier frame acts as an intermediary structure between the patient and the imaging equipment. It provides a stable reference framework that mediates the positioning of various body parts, ensuring consistent alignment with the energy receptor while maintaining a relatively simple overall device structure.
2Adaptability or versatility
If the patient barrier is made more adjustable to accommodate varied arm lengths and positioning needs, then patient positioning stability improves, but the device complexity increases
Solution Approach 1:
The support bars are designed with pivot capabilities, allowing them to move from a stored position to an operational position and be adjusted to different angles. This dynamic adjustment capability enables accommodation of varied arm lengths and positioning requirements while maintaining a compact form when not in use, balancing adaptability with device simplicity.
Solution Approach 2:
The frame structure serves multiple functions: it supports the footstep, holds the support bars, provides pivoting points for adjustment, and acts as a barrier between the patient and energy receptor. This multi-functionality reduces the need for separate components, maintaining device simplicity while achieving high adaptability for different patient needs.

AI summary
A patient barrier is described. The patient barrier includes a footstep configured to support a patient and placed on a floor, a frame attached to the footstep and configured to separate the patient from an energy receptor The patient barrier includes at least one of a first pivot configured to pivot the patient barrier with respect to the floor, and a support bar coupled to the frame, configured to support an arm of the patient, and pivot with respect to the frame.
