We identified that one of the indirect effects resulting from the current pandemic is the decrease in the population use of hospitals (public and private), and other health system equipments, due to fear contagion by Covid-19, which may result in numerous health issues for residents, not directly related to the virus.

When the current crisis is over, the project will be scaled and multiplied, and will function at the forefront of basic health units, operating off-grid when necessary, in a technological and punctual way with pre-scheduling and screening by mobile app. By this way reducing costs for the health system and democratizing universal access to health and quality care; no queues and no surprises.

The project is currently in Detail Design, phase and the first operational prototype is expected to be presented in a month.
