Engineering students develop low-cost infusion pump
People go to hospitals putting their faith and trust in the healthcare system to restore them back to a healthy condition. But this trust is slightly misplaced when physicians and nurses are unable to help patients due to the lack of resources and expensive equipment.
To combat this problem, engineering professors and students are taking matters into their own hands and coming up with economical, locally produced alternatives to imported medical equipment. Recently, a professor at Information Technology University (ITU) had developed a low-cost ambu bag ventilation system and now a group of students at the university have taken things further and have invented a low-cost infusion pump.
An infusion pump is a device that delivers fluids, nutrients or medication into a patient’s circulatory system at a precisely controlled rate.
The pump is used to deliver fluids such as insulin, antibiotics, chemotherapy drugs, pain relievers and even other hormones. It is most commonly used for intravenous infusions, but subcutaneous, arterial and epidural infusions can also be used.
Infusion pumps can provide fluids at a rate or quantity that would be too expensive or too inaccurate if performed manually by doctors or provided in the form of a drip. These pumps have the capability of delivering fluids in amounts smaller even than those provided by drips; they can infuse amounts as small as 0.1 mL per hour injections.
They also provide medication with volumes varying according to the time of day and administer injections at fixed intervals like every minute or every hour. They allow patients in pain to administer their own pain medication in a safe manner, with multiple boluses as requested up to a predetermined maximum number per hour.
