Innovation and Development of a Mobile Temperature - Controlled Vaccine Condo Bag Innovation and Development of a Mobile Temperature - Controlled Vaccine Condo Bag

Abstract

This research and development study aimed to: 1) investigate the current situation, problems, and needs of vaccine recipients regarding temperature control; 2) develop an innovative portable temperature – controlled bag; and 3) evaluate its effectiveness. Using Design Thinking methodology, a prototype bag was developed with polyurethane leather, insulation lining, LCD temperature display, and three 100g cooling gel packs.
The innovation was tested with 30 village health volunteers and satisfaction was assessed among 52 cholera vaccine service recipients. Data analysis employed descriptive statistics and Chi–square tests.

            The study found that a large number of vaccine recipients were required to take the vaccine home for oral administration, but a high proportion lacked appropriate temperature – control equipment. Interviews with vaccine recipients revealed several obstacles, including time constraints, difficulty in obtaining suitable equipment, and concerns about hygiene. These findings underscore the need for a standardized, user – friendly device that allows the general public to conveniently maintain proper vaccine storage conditions. In terms of the innovation’s effectiveness, it was found that it could maintain a temperature range of 2 – 8°C for over 6 hours, significantly outperforming existing equipment (p < 0.00001). A satisfaction survey among 52 users revealed the highest satisfaction level (mean = 4.93, SD = 0.21). User feedback reflected convenience, time savings, and confidence in vaccine quality. This innovation has high potential for practical implementation in both healthcare units and situations requiring transportation of vaccines or medications that require temperature control.
