Manufacturing/Building Method

The ECGF device prototypes were manufactured in Uganda. The device is still in prototype phase and not yet manufactured at scale.

Intellectural Property Type

Select Type

User Provision Model

The device is still in prototyping phase and so the designers have not yet selected their user provision model.

Distributions to Date Status

To date, 5 prototypes have been manufactured and used for clinical testing. There are no market distribution for the product yet.

Delivery depths

Intravenous delivery

Maximum injection volume (mL)


Design Specifications

The ECGF device is designed to accurately administer fluids and other therapeutics intravenously by controlling the rate of fluid flow based on feedback from a drop sensor. An actuator is used to control the flow of fluid. The device uses both a mains and solar battery. The device automates the regulation of fluid and drug delivery and removes the need for manual regulation, as is the current standard in Uganda. To set the desired flow rate, the user uses the device keypad to type in the desired flow rate.

Product Schematics

Technical Support

Provided by the manufacturer.

Replacement Components

The device battery must be replaced after is maximum recharge cycles.


Battery life is approximately 8 hours.

Manufacturer Specified Performance Parameters

Manufacturer specified performance targets include safety, accuracy, ease of use, and maintainability.

Vetted Performance Status

5 prototype devices were built and pre-clinically tested in 2017. After the initial testing, clinicians were trained to install and operate the ECGF device where the time required for clinicians to regulate and monitor fluids was studied. During the clinical trial, 79 nurses, doctors, and biomedical technicians from 3 health facilities were trained on the ECGF device. Both user experience data, such as ease of set up, usability, functionality, safety, and ergonomics, as well as analytical data was collected. The analytical data focused on flow rate accuracy. In the first human pilot consisting of 12 adults, the device achieved a flow rate accuracy (ie. percentage error margin between the prescribed and actual dosages) of +/- 7%. A clinical safety trial for children aged 5-8 was conducted and found that the most notable improvements by the ECGF device were in children suffering from malaria, dehydration, severe diarrhea, and pneumonia. A final clinical trial for children aged up to 4 years was completed in early February 2019 and the analysis is being finalized. The clinical trials had 160 participating children.


The device features several safety systems such as alarms for rate of infusion (rapid or slow), total volume, and faulty sensors. A safety trial was conducted with adults and children. The team is improving the ECGF design to further improve the flow rate regulation.

Complementary Technical Systems

The ECGF device is compatible with existing intravenous drips.

Compliance with regulations

The designers are planning to obtain CE marking for the device.

Evaluation methods

The product has been evaluated for flow rate accuracy, ergonomics, safety, and ease of use.

Other Information

The development of the ECGF device was sponsored by Grand Challenges Canada in the Stars in Global Health program from 2017-2018. The ECGF device won second prize in the Health and Wellbeing Innovations Category at the 2017 IPA Awards in Accra, Ghana.
