Further Development of a Robotic-Assisted Transfer Device

Area of Science:

• Rehabilitation Engineering
• Assistive Technology
• Human Factors Engineering

Background:

• Manual patient transfers, like wheelchair to bed, pose significant injury risks to both individuals and caregivers.
• Existing mechanical transfer devices have limitations for community use and can still strain caregivers.
• The need for safer, more accessible transfer solutions is critical in healthcare and home settings.

Purpose of the Study:

• To gather user feedback on the Robotic-Assisted Transfer Device (RATD) through focus groups.
• To identify necessary design modifications for advancing the RATD towards market readiness.
• To assess the potential adoption of the RATD by end-users and caregivers.

Main Methods:

• The Robotic-Assisted Transfer Device (RATD) was integrated with an electric-powered wheelchair (EPW).
• Key device components underwent redesign, and the control system was updated to enhance safety.
• Focus groups comprising individuals with disabilities, clinicians, and caregivers were conducted to collect user input.

Main Results:

• Enhanced safety features include error checking, safety zones, a motor brake, and an improved track system.
• A significant majority expressed willingness to use the device: 63% of individuals with disabilities and 83% of caregivers.
• User feedback positively influenced the device's safety and usability.

Conclusions:

• Focus group feedback was largely positive, indicating successful design improvements for the RATD.
• The implemented design changes have enhanced the device's safety and user-acceptability.
• Further development is required before the Robotic-Assisted Transfer Device (RATD) can be commercialized.
