Abstract:
Currently, Thailand has stepped into an aging society. It is expected that in the year 2033 there will be
a proportion of the population aged 60 years and over in the rate of 28 percent of the total population. The
increase in the aging population will bring with it more health problems and the need for more care, especially
the demand for medical equipment. Including facilities or technological innovations to help take care of the
elderly and reduce the dependency of the elderly. Survey data show that from the 1970s, one elderly person
had approximately 13 caregivers. However, today, one elderly person has approximately four caregivers. In
2030, it is expected that one elderly person will have only about 2 caregivers. In addition, the aging society
situation has led to health problems, which can be considered a constant issue for the elderly. Especially for
elderly people who have chronic illnesses, they often need to take multiple medications and/or have complex
medication management. This can create confusion in medication adherence for the elderly. The automated
medication dispensers for the elderly is therefore considered a device that can help reduce risk, complexity,
and the impact of taking various types of medications that are not appropriate for the elderly. However, the
mechanism of drug delivery within the automated medication dispensers can generate forces due to reactions
from the various components within, which can affect the structural strength of the automated medication
dispensers. Therefore, this research analyzes the distribution of normal stress and displacement within the
mechanical design of the automated medication dispensers, in order to study its structural strength and provide
guidelines for its design. The 3D model of medication dispensers is developed. The results of the study revealed
that using an acrylic thickness of 2 mm, the normal stress and displacement values are greater than using an
acrylic thickness of 3 mm with forces of 50 N and 100 N. In addition, applying forces of 100 N, the normal stress
and displacement values are greater than applying forces of 50 N with acrylic thickness of 2 mm and 3 mm.
The results of this research found that the strain distribution within the mechanical design of the automated
medication dispensers did not exceed the predetermined strength limit, leading to a foundation for the design
of the automated medication dispensers and various medical devices
