The
Sarco device is a euthanasia device or machine consisting of a 3D-printed detachable capsule mounted on a stand that contains a canister of liquid nitrogen to commit suicide through inert gas asphyxiation. "Sarco" is short for "sarcophagus". It is used in conjunction with an inert gas, nitrogen, which prevents the panic, sense of suffocation and struggling before unconsciousness, known as the hypercapnic alarm response caused by the presence of high carbon dioxide concentrations in the blood. The Sarco was invented by euthanasia campaigner Philip Nitschke in 2017. Nitschke said in 2021 that he sought and received legal advice about the device's legality in Switzerland.
