Sterilization medical equipment

Maintain sterile medical environment

Project Title: Sterilization of Medical Equipment in a Third World Country: A Minor Field Study in Linga Linga, Mozambique
Students:  Haya Abduljabar, Hanan Hadi
School: Royal Institute of Technology (KTH), Stockholm
Degree: Bachelor of Engineering
Major: Medical Engineering
Program: Minor Field Study (MFS), Swedish International Development Cooperation Agency (Sida)

This project was realized in 2020 by Haya Abduljabar and Hanan Hadi. It was meant to be through a Field Study but due to the Covid-19 pandemic it had to be conducted remotely.

In this project realized in 2020, students Haya Abduljabar and Hanan Hadi worked with Project Vita to assess what measures existed or could be developed to improve the sterilization of medical equipment Project Vita has recently built a maternity clinic in Linga Linga, where medical instruments to be sterilized are boiled in water for an hour. The fuel needed to boil the water is wood, a scarce resource. A healthcare worker interviewed during the study expressed the desire to have an electricity-powered solution to sterilise the medical instruments.The students investigated alternatives that would use locally sourced materials  and would allow sterilization to be done as energy efficiently as possible given the limited availability of electricity in the area.

They concluded  that the safest way to sterilize equipment is by using an autoclave. However, it would be difficult to implement and maintain an autoclave in Linga Linga. It was therefore proposed to build an autoclave using a pressure cooker. By experimenting with  different programs, times, and pressures, the students found that using a pressure cooker t could sterilize common objects. Further on-site testing is needed  to determine whether the solution works in a practical setting.
