Mixed Reality Control Projection for Sterile Field Device Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clinicians face difficulties in interacting with or changing parameters of medical devices located outside the sterile field without compromising sterility, leading to time inefficiencies and the need for reagents to maintain sterility.
Innovation Solution
A medical device projection system that includes a projector within the sterile field to project a mixed reality visual representation of a user control interface, allowing clinicians to control medical device parameters from within the sterile field using buttons or a display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clinician exits the sterile field to interact with the medical device, then the clinician can control the medical device parameters, but the sterility of the field is compromised and repeated sterilization is required
Solution Approach 1:
A projector is introduced as an intermediary device that bridges the sterile and non-sterile zones. The projector displays the medical device's control interface within the sterile field, allowing the clinician to interact with the device without physically entering the sterile zone, thus maintaining sterility while enabling device control
Solution Approach 2:
The projector creates a visual copy or representation of the medical device's control interface within the sterile field. This projected interface allows the clinician to interact with the device parameters remotely, eliminating the need to compromise sterility for device control
2Reliability
If the clinician remains inside the sterile field to maintain sterility, then the sterile field integrity is preserved, but the clinician cannot interact with the medical device located outside the sterile field
Solution Approach 1:
The projector serves as a mediator that extends the control interface into the sterile field. By projecting the control interface within the sterile zone, the system enables interaction with the medical device while the clinician remains in the protected sterile environment
Solution Approach 2:
The system transitions the control interface from a physical dimension (outside the sterile field) to a visual projection dimension (inside the sterile field). This allows the clinician to interact with the device through a projected representation rather than direct physical contact, maintaining sterility while enabling control
3Ease of operation
If the medical device is placed inside the sterile field to enable direct control, then the clinician can directly interact with the device, but the device and its controls are exposed to contamination risk
Solution Approach 1:
Instead of placing the physical device inside the sterile field, the system projects a visual copy of the device's control interface within the sterile field. This allows direct interaction with the device while the actual device remains outside the sterile zone, protected from contamination
Solution Approach 2:
The projector acts as an intermediary that brings the control interface into the sterile field without bringing the physical device. This separation allows the device to remain protected from contamination while still enabling direct clinician interaction through the projected interface
