Key Findings

01A Control Head Holder (CHH) can reduce physician fatigue during colonoscopy.
02A Splatter Shield with a Tube Holder (TH) can mitigate exposure to bodily fluids and provide hands-free support for the insertion tube.
03Prototype testing validated the functional requirements of the developed devices.

Application

Design takeaway

How to apply

When designing any tool or equipment used in repetitive or high-risk tasks, conduct user observations and interviews to identify ergonomic stressors and safety vulnerabilities, then develop prototypes that directly address these issues.

Project actions

01Observe users performing tasks to understand their physical challenges.
02Interview users to gather direct feedback on pain points and safety concerns.
03Prototype solutions that address both ergonomic and safety issues.

Method & Evidence

AimTo develop and evaluate medical equipment that enhances the safety and comfort of physicians during colonoscopy procedures.

MethodObservational study, user interviews, prototype development, and functional testing.

ProcedureThe study involved direct observation of colonoscopy procedures, interviews with physicians to identify safety concerns, the development of a Control Head Holder (CHH) and a Splatter Shield with a Tube Holder (TH), fabrication of prototypes, and subsequent testing including drop tests, drop ball tests, and force sensor measurements for the TH, along with fatigue reduction assessment for the CHH.

ContextMedical device design, surgical procedures, occupational health and safety.

Variables

IV["Design of Control Head Holder (CHH)","Design of Splatter Shield with Tube Holder (TH)"]

DV["Physician fatigue levels","Exposure to infectious splatters","Ease of performing procedure","Force required for slippage from TH"]

CV["Type of medical procedure (colonoscopy)","Existing colonoscopy equipment","Environmental conditions of testing"]

Strengths & Limitations

Strengths

+Direct observation and user interviews provided rich qualitative data.
+Prototype development and testing allowed for validation of design concepts.

Limitations

Testing with a small group of users or in a simulated environment may not fully represent real-world conditions.

Reliability & validity

The study's validity is supported by direct observation and user feedback, but reliability of fatigue measurement might be improved with standardized physiological monitoring. The drop tests and force sensor measurements offer objective data for specific components.

Think critically

How might the cost and complexity of implementing these specialized tools impact their adoption in clinical practice, and what design strategies could address these barriers?

Design Principles

"Design for occupational safety and ergonomic efficiency in medical procedures."

This research highlights the critical need to consider the physical and safety well-being of healthcare professionals in the design of medical tools. By addressing ergonomic challenges and potential biohazards, designers can improve the working conditions and long-term health of physicians, ultimately leading to better patient care.

What This Means for Your Design

Special tools can make colonoscopies safer and less tiring for doctors by holding equipment steady and blocking splashes.

How to use in your project

1.Reference this study when discussing the importance of ergonomic design and user safety in your own design project.
2.Use the findings to justify the inclusion of specific features in your prototype.
