The Sarco uses a little over 4 liters of LN2 to drop the oxygen level within the capsule to less than 5% in under a minute. It does this silently. The person inside the Sarco will die within a few minutes.
The Sarco base (the generator) and the capsule are both 3D- printed. The capsule can also be used as a coffin. The base containing the liquid nitrogen evaporator can be reused.
Use of the Sarco will ultimately require the safeguard of an online medical capacity test (using AI - artificial intelligence). This test is in development. Successful completion of the men- tal capacity test will generate a four-digit access code which will be valid for 24 hours, and will allow the activation of the Sarco.
Testing and Operation
The first Sarco was 3D-printed in Haarlem in the Netherlands between 2018 - 2020. As large-scale 3D printers are not yet easily accessible, Exit is exploring the ways and means of making pre-manufactured model Sarcos available. The Sarco plans will be published in the eHandbook.
Stage 1 (in vitro) testing of the Sarco was carried out at the Exit workshop in the Netherlands in 2019 and confirmed the rapid drop of oxygen within the capsule to less than 5% within 30 seconds of device activation.
Stage 2 (in vivo) Sarco testing is planned for Switzerland in 2021. The first person to use Sarco will be monitored with ECG and SaO2 pulse oximetry. Results will be published on completion of the tests.
