Hospital Bed Headrest Tilt Indicators for Proning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hospital beds for proning patients lack tilt indicators, making it difficult for caregivers to accurately position the patient's head, leading to undesirable pressure distribution and potential skin injuries due to improper positioning.
Innovation Solution
A head rest accessory for hospital beds featuring a frame with parallel rails, a crossbeam, and releasable clamps, allowing for adjustable positioning and including a face rest shell with a T-shaped cutout for the patient's face, along with integrated angle sensors to indicate tilt angles, facilitating precise head positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If tilt indicators are added to the head rest accessory, then measurement precision of head positioning is improved, but device complexity increases
Solution Approach 1:
The patent uses visual indicators (such as colored lines, arrows, or illuminated markers) on the head rest accessory to display tilt angle information. These visual elements change their appearance or position to indicate different tilt positions, allowing caregivers to accurately assess head positioning without complex electronic displays or measurements.
Solution Approach 2:
The patent introduces an intermediary component (such as a separate indicator panel, marker, or visual reference system) that mediates between the head rest structure and the caregiver's observation. This intermediary provides the tilt information in a form that is easily perceivable and interpretable, decoupling the measurement function from the main structural complexity.
2Adaptability or versatility
If the head rest is made repositionable along the rails, then adaptability to different patient morphologies is improved, but ease of operation deteriorates due to frequent adjustment
Solution Approach 1:
The patent implements a dynamic positioning system where the head rest can be moved along the rails using simple mechanical mechanisms (such as sliding blocks, clips, or latch systems). The structure transitions between fixed and movable states, allowing easy repositioning when needed while maintaining stability during use. The dynamic nature of the system enables adaptation to different patients without complex adjustment procedures.
3Productivity
If pre-setting of head rest position is enabled, then productivity of positioning process is improved, but loss of information about patient-specific requirements increases
Solution Approach 1:
The patent allows caregivers to pre-set the head rest position based on general patient morphology categories or anticipated requirements before the patient is positioned. The system provides preset positions (such as neutral, lateral tilt, or extended angles) that can be quickly selected and adjusted. This preliminary action eliminates the need for time-consuming measurements during the actual positioning process while still allowing customization based on individual patient needs.

AI summary
A head rest accessory is provided for coupling to a bed frame of a hospital bed. The head rest accessory includes a frame and a head rest mount coupled to the frame. A head rest is coupled to the head rest mount and includes a face rest shell. A first angle sensor measures a first tilt angle of the face rest shell. A second angle sensor measures a second tilt angle of the face rest shell.
