Multi-dose pneumatic emergency injector for EMS and first responders.
Delivers multiple sterile, life-saving doses in the field—without switching devices or breaking the flow of patient care.
Built for chaotic, high-stress emergencies where every second matters.
lifeAID®
Multi-Dose Pneumatic Auto Injector.
SYNOPSIS
Most emergencies require more than one dose, yet today’s auto-injectors deliver only a single injection. LifeAID is a multi-dose pneumatic injector with three pre-filled sterile cartridges, designed to support EMS and first responders during time-critical care.

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.
Seamless Sequential Delivery
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 (5 years)
I’ve treated patients who needed more than one injection, but I only had a limited number of single-use auto-injectors. A multi-chamber injector would let me respond quickly without digging for spares.

Squad Leader – Contreras (6 years)
"As a leader, I need to know my team has enough medical coverage. If more than one soldier needs treatment, single-use injectors run out fast. A multi-dose device could buy us time until medics arrive."
-
Infantryman – Long (6 years)
"On missions, I already carry too much gear. Packing several different injectors for different scenarios is inefficient. A single device with multiple cartridges would cut weight and give me peace of mind."
