Nereus Medical
Our mission is to provide organisations with effective, evidence based and innovative products, solutions and strategies for the prevention, diagnosis and management of heat illness in sport, high risk occupational settings and the military.
Our founder, Dr Ross Hemingway OBE, recognised the requirement for a lightweight, portable and robust system to enable the rapid cooling of patients who have developed heat stroke. The system, the Ice-Cold Water Immersion Kit (I-CWIK®) has been designed for use by medical teams across a wide range of environments. This includes mass sporting events, elite sporting competitions, hospitals, emergency medical services, high risk occupational environments and the military.
I-CWIK®
Ice-Cold Water Immersion Kit
The I-CWIK® is a portable, robust PVC bag for use in environments and situations where the risk of heat illness is increased, and the gold standard of treatment using cold water immersion is required as a key capability. The design with YKK AQUASEAL® waterproof zips, adjustable volume, carry straps, novel emptying system and fully customisable colour design to match your brand, makes it an indispensable piece of equipment for these teams.
The I-CWIK has been manufactured using only the highest quality materials and components from leading UK manufactures. This ensures the I-CWIK can be relied upon in the most demanding and arduous environments.
Buckles
The YKK Shockonloc® dual adjustment buckles provide toughness and reliability during ice cold water immersion of patients. Manufactured from high-grade polyacetal, the buckles provide strength and durability against impact and resist water absorption in the most extreme environmental conditions.
AQUASEAL Zips
Both of the I-CWIK’s zips are YKK’s AQUASEAL® lightweight fully waterproof zips combining VISLON® technology, which allows for easy and smooth operation with protection in critical medical situations. The plastic and stainless sliders have high resistance to corrosion in the most extreme of conditions.
Carry Straps
The 4 sets of carry straps manufactured by the leading UK webbing manufacturer WISLA, are 50mm width filament polyester with a minimum breaking strength of 3000kg and impregnated with antimicrobial and antifungal coatings to reduce contamination and colonisation risk from common microbes.

Exertional Heat Illness
Heat-related deaths in Europe between 30 May and 4 September 2022
Mortality rates for Exertional Heat Stroke
Survival in those treated with Ice-Cold water Immersion in road races and the military
Recreational and elite athletes, military personnel, and certain high-risk occupations are all vulnerable to developing exertional heat illness symptoms, which can range from mild heat exhaustion to severe exertional heat stroke. While more prevalent in hot and humid environments, heat-related illness prevention is critical even in cooler and temperate climates where heat stress in athletes is still a concern.
EHI includes a spectrum of conditions, from heat injury and exertional heat exhaustion treatment to the potentially fatal heat stroke emergency treatment. Early signs such as fatigue, nausea, and dizziness should be recognised promptly to avoid progression to confusion, collapse, seizures, or cardiac arrest.
The most critical stage, exertional heat stroke protocol, requires immediate intervention. Current international consensus supports cold water immersion therapy as the gold standard for rapid and effective whole-body cooling, which drastically reduces heat illness complications and the risk of death or permanent disability.
