Faucetworks is developing the Faucet™ artificial intelligence diagnostic (AID), a medical device that is capability of diagnosing neurological emergencies such as stroke in the ambulance.  Rapid diagnosis in the ambulance leads to immediate treatment and the reduction of brain damage, improving the patient’s neurological condition while facilitating use of existing therapies and enabling use of new therapies. 

Here is what the Faucet will look like:

Our Faucet AID will be a cloud-based, semi-autonomous artificial neural network endowed with natural language and visual recognition capabilities that can diagnose neurological emergencies (e.g., stroke, traumatic brain injury [TBI]) by direct communication with, and examination of, the patient.  Once the diagnosis is established, the Faucet AID will then direct emergency treatment measures and guide patient transport to an appropriate hospital (Stroke Center, Trauma Center).  Patients who have uncertain diagnoses will be referred to on-call physicians for evaluation.  However, the machine learning capability of the Faucet AID will, over time, increase its diagnostic accuracy, allowing for expansion of the service.





Direct patient interaction leads to diagnosis and treatment of neurological emergencies in the ambulance.  Neurological emergencies that are currently treatable, such as ischemic stroke, must be distinguished from similar conditions ("stroke mimic" conditions).  Physician backup is always available but becomes less-frequently needed over time as the Faucet improves its diagnostic accuracy.

But other technologies are also needed to enable treatment of neurological emergencies in the ambulance.  Read about how brain hemorrhage detectors will help the Faucet treat stroke in the ambulance.  Also read about what sort of treatments are currently available for use in ambulances to treat neurological emergencies such as ischemic stroke, such as the clot-busting medication tissue plasminogen activator.




Stroke is the most common cause of disability and the second most common cause of death globally.  In the US, nearly 800,000 cases of stroke occur each year, costing approximately $37 B in healthcare expenditures.  Worldwide, there are more than 16.9 M cases of stroke annually of which 5.7 M prove fatal.  Ischemic stroke, which accounts for 85% of all stroke, currently can be treated in the ambulance with the intravenous ‘clot busting’ medicine, tissue plasminogen activator, if only the patient diagnosis were available in that setting.

TBI affects 1.7 M Americans each year, leading to 1.3 M emergency department visits and 275,000 hospitalizations.  It causes 52,000 fatalities and costs $60 B in healthcare expenditures annually.  Some 40 M cases of TBI occur worldwide each year.  No specific treatment for TBI currently exists for use in the ambulance, though future treatments could be used in ambulances if the patients could be diagnosed beforehand.

The Faucet AID will diagnose stroke and TBI of any severity, as well as conditions that resemble stroke and TBI, which are about 3-fold more common.  Furthermore, additional emergency conditions may ultimately be managed by the Faucet AID once the technology is in established use in ambulances.

Because it is scalable, the Faucet AID can be used in any and all of the approximately 81,000 ambulances in the U.S. and 178,000 ambulances in Europe.  Emergency departments in hospitals that lack adequate physician services may similarly benefit from the Faucet AID.
