Arched Projection Screen for Free Patient Head Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for image projection during surgery do not allow patients to move their heads freely while viewing images, and they often restrict the movement and visibility of healthcare professionals, leading to increased patient anxiety and confinement.
Innovation Solution
A projection screen with an arched laminar body that allows patients to view projected images without restricting their head movement, while also enabling healthcare professionals to monitor patient signs and symptoms and perform procedures without obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a projection screen is placed close to the patient's face to allow image viewing, then the patient can see images during surgery, but the patient's head movement is restricted and healthcare professionals cannot monitor the patient properly
Solution Approach 1:
The patent transitions from a two-dimensional flat screen to a three-dimensional arched dome structure that envelops the patient's field of view. This dimensional change allows the screen to be positioned overhead without blocking the patient's ability to move their head or interact with healthcare professionals, while still providing comprehensive image coverage from multiple angles.
Solution Approach 2:
The projection screen is designed with an arched, dome-like curvature rather than a flat surface. This curved geometry distributes the projection area across an arc that spans overhead, allowing patients to view images from various head positions and angles without the screen obstructing their movement or the healthcare professionals' access to the patient.
2Loss of information
If a flat projection screen is used, then images can be projected during surgery, but the screen obstructs healthcare professionals from monitoring patient signs and performing procedures
Solution Approach 1:
By elevating the projection screen to an overhead arched structure, the system moves the display out of the horizontal plane where healthcare professionals work. This vertical dimensioning allows simultaneous patient monitoring and surgical procedures without visual obstruction, as the screen arches overhead while maintaining clear sightlines for medical staff.
3Adaptability or versatility
If a complex projection system is introduced to allow patient viewing during surgery, then patient comfort and psychological wellbeing improve, but the equipment cannot be easily introduced under sterile conditions and reused
Solution Approach 1:
The projection system is divided into separate sterilizable components: the arched screen structure can be detached and sterilized independently, while the projection device can be positioned outside the sterile field and connected via sterile barriers or transparent drapes. This segmentation allows the complex system to be introduced and reused under sterile surgical conditions.
Solution Approach 2:
The patent employs sterile barriers, transparent surgical drapes, or isolators as intermediary elements between the non-sterile projection equipment and the sterile surgical field. This allows the projection system to function without compromising sterility, enabling reuse of equipment while maintaining sterile conditions.
4Illumination intensity
If existing projection systems are used, then images can be displayed during surgery, but the systems do not allow patients to move their heads freely while viewing
Solution Approach 1:
The arched dome configuration creates a three-dimensional viewing environment where images are projected across a curved surface overhead. This allows patients to move their heads freely in multiple directions while maintaining visibility of the projected content, as the arched structure provides comprehensive angular coverage unlike flat screens that require fixed viewing positions.

AI summary
A back projection screen that allows the awake patient to move the head and neck freely and yet be able to look at the images that are displayed during surgery, but at the same time allows a surgery crew, in particular an anesthesiologist, to watch the airway passage and the consciousness state of the patient, and to monitor signs including color of the lips, eyes movement, verbal responses, skin sensitivity, and the like, as well as to maneuver for intubation or other procedures without removing the screen during surgery. The back projection screen allows also eye contact and/or face to face interaction, physically or virtually, with the surgeon or other members of the surgery team for effective communication and is suitable for easy cleaning or disinfection from bacteria or viruses as required by operating rooms.
