Introduction :
Occupational Therapy services in Hong Kong are always committed to design and prescribe different aids and gadgets to facilitate independent living for all elderly and the disabled. Manipulating Ventolin puff has been a difficult task for patients with hand function impairments. By making use of 3D printing technology, Occupational Therapy Department in Caritas Medical Centre has designed a special handle to facilitate independent use of Ventolin puff. The tailor- made adaptive device was chosen to illustrate the benefits and importance of utilizing appropriate assistive technology in patient care.
Objectives :
To explore and analyze the force required and hand grip difference before and after using this 3D printed Ventolin puff adaptive handle.
Methodology :
Chatillon DF II digital force gauge is used to measure the force required to activate the trigger of Ventolin puff before and after using the 3D printed handle. The lesser force is required, the easier for the patient to complete the task (press the trigger and release the drug). The ergonomic efficiency in hand/ fingers position with or without the assistive device are also analyzed and compared in this study
Result & Outcome :
The 3D printed puff adaptive handle can significantly reduce the force required (Reducing from average 10.7 lbf to average 3.57 lbf, over 60% reduction). By making use of lever system, the assistive device can reduce the stress on finger small joints and in turns immediately improve the efficiency and reduce the effort. In conclusion, Occupational Therapy 3D printing design is a cost-effective approach to fabricate customized tools to promote patient’s independent living.
