Detachable drive unit for assistant controlled manual wheelchairs

Area of Science:

• Biomedical Engineering
• Rehabilitation Engineering
• Assistive Technology

Background:

• Manual patient mobility presents challenges for healthcare staff.
• Existing solutions may lack portability or ease of use.
• Need for efficient patient transfer and transport systems in healthcare settings.

Purpose of the Study:

• To design and develop a self-contained power unit for unpowered wheelchairs.
• To evaluate the performance of a prototype wheelchair assistance device.
• To provide a solution for assisting porters and nurses with patient mobility.

Main Methods:

• Design of a portable, clamp-on power unit.
• Integration of the unit with standard unpowered wheelchairs.
• Performance testing of the prototype in simulated healthcare environments (e.g., ramps, corridors).

Main Results:

• A functional prototype of the wheelchair power unit was successfully developed.
• The unit demonstrated effective assistance in overcoming common mobility challenges.
• Ease of attachment and detachment was confirmed during testing.

Conclusions:

• The developed power unit offers a practical solution for enhancing patient mobility assistance.
• This assistive technology can reduce physical strain on healthcare personnel.
• Further development could optimize performance and expand applications.
