Most auto injectors deliver a single dose, but real emergencies often demand more. Overdose reversal, severe hypoglycemia, and anaphylaxis can require repeated injections within minutes. Mass casualty situations amplify that demand. LifeAID is a pneumatic emergency auto injector with three rechargeable cartridges, enabling rapid multi dose deployment from one compact device when seconds matter.

TOOL
Problem
Most emergencies require repeat dosing. Research shows that up to 36 percent of anaphylaxis cases and nearly 80 percent of opioid overdoses need more than one injection. Because most auto-injectors are single-use, responders must stop and open a new device each time a patient needs another dose or when another patient requires immediate attention. This slows treatment and interrupts workflow during the moments when speed and clarity matter most.
Auto-injectors deliver only one dose and must be replaced each time.
This creates extra steps during repeat dosing or when treating multiple patients.
Opportunity
Make repeat dosing immediate and uninterrupted.
Solution
LifeAID combines three pre-filled sterile cartridges into one pneumatic injector, allowing EMS and first responders to deliver repeat doses instantly without switching devices. It keeps treatment continuous, fast, and controlled during high-pressure emergencies.
Instant Response
First dose fires immediately for rapid action.
Cartridge Reload
After each injection, replace the used needle cap. Then turn the Rotary Grip clockwise until it clicks and locks. The tactile and audible feedback confirms the next cartridge is ready.
Fast Priming
After three doses, the actuator resets upward. Pump three times until it locks, then rotate to unlock and LifeAID is ready again.
LifeAID’s triple-cylinder system delivers uninterrupted, back-to-back doses, eliminating delays when every second matters.

Impact
Keeps care continuous by delivering multiple doses without interruption, allowing responders to stay focused on patients—not devices.
Form
The cylindrical body efficiently houses three rotating cartridges and keeps each dose aligned to the same injection point. The form is driven by tight internal packaging and consistent external usability.
User Interview
These interviews with field medics, military personnel, and first responders grounded the project in real operational needs and shaped the requirements for speed, repeat dosing, and reliability.
-
Doctor – Augir
“I’ve been in situations where a second dose was needed right away, but I only had single-use injectors available. When time matters, switching devices slows everything down.”
-
Medic – Pacheco
“In the field, I can’t sort through gear. If a patient needs more than one injection, I want to perform it quickly without searching for spares.”
-
Squad Leader – Contreras
“My biggest concern is making sure my team has enough medical support during an emergency. If more than one person needs treatment, single-use injectors disappear fast.”
