Born from
tragedy.
Built to save
the next life.

Purpose-built technology being developed for rapid response to catastrophic bleeding involving the neck — engineered with the same urgency as the moment it answers.

Their Legacy

Two lives. One responsibility: build something that may help the next person.

KIRK™ Collar was inspired by the devastating reality of catastrophic neck trauma. This project honors Charlie Kirk and Iryna Zarutska by focusing on preparedness, engineering, and the value of every human life.

Memorial portraits of Charlie Kirk (1993–2025) and Iryna Zarutska (2002–2025), with the line: Two lives. Two tragedies. One mission. Remember the lives. Change the outcome.

A note on this tribute

KIRK™ Collar is an independently developed initiative. This project is not sponsored, endorsed by, affiliated with, or approved by the estates, families, or foundations of Charlie Kirk or Iryna Zarutska. Their circumstances were different — the medical emergency in each exposed the same vulnerability: when catastrophic neck bleeding occurs, time and effective intervention matter.

If you are a family member or authorized representative and would like to request a factual correction or discuss this memorial treatment, please contact us directly.

02 — The Problem

Neck trauma breaks
the standard playbook.

Extremity tourniquets are designed for limbs. The neck holds airway and vascular structures side by side, so a specialized, purpose-built device requires careful engineering, human-factors testing, and medical validation — not an improvised workaround.

“Uncontrolled traumatic bleeding is a leading cause of preventable death.”

American College of Surgeons — Stop the Bleed

“Rapid bleeding control matters because trauma outcomes are highly time-sensitive.”

American College of Surgeons — Stop the Bleed

“Direct pressure, wound packing, and extremity tourniquets are established first-aid techniques for appropriate wounds.”

Required safety guidance

In an emergency, call 911 or your local emergency number immediately and follow established bleeding-control training. KIRK™ Collar is a development-stage device and is not intended to replace emergency medical services or established trauma protocols. Do not place a standard limb tourniquet around the neck.

03 — The Collar

Engineered for the
most critical moments.

KIRK Collar product render with callouts for airway protection, targeted compression, rapid deployment, adjustable fit, visual guidance, and compact and lightweight design
DESIGN INTENT

Targeted compression

Architecture intended to focus intervention at the wound region while avoiding indiscriminate circumferential neck compression.

DESIGN INTENT

Airway-aware geometry

The concept is designed with the airway and anterior neck anatomy in mind, not around it.

PROTOTYPE

Rapid deployment

Engineered toward a small number of stress-tolerant actions, aimed at deployment under extreme pressure.

PROTOTYPE

Adjustability

An accommodation strategy for patient anatomy and wound location, to the extent supported by current design.

DESIGN INTENT

Compact readiness

Intended for placement in EMS, trauma, tactical, or institutional kits as the packaging model matures.

Status badges reflect current engineering maturity, not regulatory clearance. KIRK™ Collar has not received FDA clearance or approval and no claims of clinical efficacy are made.

04 — How It Works

Deploy in seconds.
That’s the goal.

Four step deployment concept: open, position, secure, tighten — shown on a training mannequin, not a real patient
01

Recognize life-threatening bleeding and activate emergency response.

02

Apply immediate, evidence-based bleeding-control measures consistent with training and local protocol.

03

Deploy KIRK™ only according to the device's validated instructions for use and user training, once finalized.

04

Maintain monitoring and transfer care to EMS / advanced medical personnel.

Important

Until instructions for use and validation are finalized, this page presents the deployment sequence as a product-development concept, not as public medical instructions. It is not a substitute for training or an approved instructions-for-use document. Photos show a demonstration on a training subject.

05 — Applications

One device.
Every mission.

06 — Research & Validation

Evidence first.
Overclaiming never.

This is where credibility is built or lost. We show what has been completed, what remains unknown, and what we are testing next.
