When a patient visits an emergency room or a new specialist, doctors and nurses need to see drug allergies, current medications, and recent test results right away, not hours later by fax. Built by Emberflow, LifeBand helps clinics and hospitals share medical records with the patient’s permission, without replacing their existing clinic software.
When a patient arrives at an emergency room far from their regular doctor, nurses and physicians need to see drug allergies, blood thinners, and heart history right away, not hours later by fax.

49.2% vs. 27.0%
Desk Work vs. Time With Patients
Doctors spend nearly twice as much time on computer and desk work as they do face-to-face with patients (Sinsky et al., 2016).

Permission Check in Sandbox Testing
In internal sandbox testing, patient permission updates in LifeBand were verified across connected clinics in under 1 second.
LifeBand uses blockchain technology to record verified patient permission and access logs on-chain, while all actual medical records stay privately stored off-chain at the patient’s hospital or clinic.
Built by Emberflow: four simple steps connect a patient’s regular doctor, specialist, and emergency room without replacing hospital software.
Using LifeBand on their phone, the patient approves which doctors, clinics, or emergency rooms can see their health history.
From their existing hospital or clinic computer, the doctor or nurse requests allergies, medications, and recent test results.
LifeBand uses blockchain technology to verify the patient’s permission and keep a tamper-proof log showing which clinic asked and when.
Actual medical files stay off-chain and are sent directly from the patient’s home clinic to the treating doctor, avoiding fax delays and repeat tests.

LifeBand works alongside the clinic software your staff already uses (like Epic, Cerner, or athenahealth), helping doctors and nurses receive outside patient records without waiting on faxes.

Review published medical studies on care-coordination waste ($27.2B to $78.2B/yr, JAMA 2019), global market forecasts (~$8.57B by 2030), and the Emberflow founding team.
During his time working in field ambulance care, Emberflow CEO Nathan Loranca saw firsthand how missing medical records affected emergency care. When patients arrived in acute distress or couldn’t speak for themselves, care teams often had no way to see severe drug allergies, blood thinners, or recent heart procedures.
Different hospitals and clinics kept records locked inside separate software systems. Sharing those records usually meant slow manual phone calls, faxed paper release forms, or repeating expensive scans.
Partnering with systems engineer Peter Kim, they founded Emberflow to build LifeBand: a patient-approved record-sharing tool that records verified patient consent on-chain while letting clinics share medical records directly off-chain alongside their existing software.
Built for real moments in emergency rooms, family clinics, and specialist referrals.
Patients choose which clinics can view their history, with every permission recorded in a clear log while medical files stay at the clinic.
Works alongside existing hospital and clinic software so care teams don’t have to migrate databases.
Articles from our founders on connecting clinic systems, emergency care workflows, and patient-controlled record sharing.
Large health networks routinely spend years of effort and major budgets on database migrations. We examine how lightweight LifeBand overlays connect existing clinic workflows without the IT overhead.

When trauma patients arrive in acute distress, waiting on faxes for medication allergies delays critical care. Emberflow CEO Nathan Loranca shares perspectives from field emergency medicine.
At Emberflow, we recognize the fundamental need for individuals to control their personal information, particularly sensitive healthcare data. Peter Kim explores why decentralization is a crucial shield to protect data integrity in the age of AI.
Imagine rushing to the ER with severe chest pain for the second time in one week, only to find your crucial medical history is inaccessible. Nathan Loranca shares why putting patients at the center of their health data is urgent.
