FAST & FOOLPROOF

In trauma situations, paramedics must act fast. Speed is crucial, requiring products to be very intuitive and easy to implement – so the vital treatments can start as soon as possible. With the °M Warmer transfusion with warm fluid can start in less than 30 seconds.

HIGH PERFORMANCE

The °M Warmer has not only extremely efficient warming capabilities (150 ml/min), fast warm-up time (less than 10 seconds) and the battery capacity to warm 1.5 litres of cold fluid (5°C), but is also designed to resist water, drop on hard surfaces and has a solid power plug that secures high performance in any emergency use.

PORTABLE DESIGN

The Power Pack and single use °M Warmer have a compact design and together weigh 760 grams making the °M Warmer System ideal for pre-hospital emergency teams. The single-use warmer’s small size (10cm x 5cm x 2cm) allows it to be attached to the patient close to the infusion site, using its integrated adhesive pad.

°M Warmer

Warm fluid helps prevent hypothermia [1]

  • Fast and foolproof setup – takes less than 30 seconds to set up and no assembly of different parts is needed. It only takes a simple 3-step procedure: Attach the IV line to the single use °M Warmer, attach the °M Warmer to the IV/OI access and connect the Power Pack
  • Extremely efficient warming capabilities – warms fluids (including blood) from 5°C to 37°C at flow rates up to 150ml/min. And on a single charge of the Power Pack, either 4 bags of 5°C cold blood (approximately 1.5 litres) or 3 litres of ambient temperature fluid can be warmed.
  • Low weight and small volume – the Power Pack and single use °M Warmer only weighs 760 grams. The size of the Power Pack is 18cm x 9cm x 3.5cm and the size of the single use warmer is 10cm x 5cm x 2cm
  • Adhesive for secure attachment close to the infusion site – the °M Warmer is equipped with an adhesive on the back, which can be used to secure the °M Warmer to the patient close to the infusion site. This drastically reduces the risk of pulling out the catheter.
  • Approved for use in helicopters and airplanes

When we treat critical patients we want the products to be intuitive and very easy to implement.

Customer segments

Military & Special Forces

Collaborating with military and special forces in the design process has resulted in a robust product which can tolerate water, drop, and rough treatment, making it resilient in a pre-hospital setting. It is also approved for use in helicopter and airplanes. The Power Pack is easy to connect to the warmer, and the connection is secured to prevent disconnection during transportation. The compact design enables the small single use warmer to be attached to the patient with the adhesive close to the IV access, reducing the risk of pulling out the catheter. Finally, the light weight makes it one of the smallest products on the market while still accommodating the high requirements from military and special forces operations.

Helicopter Emergency Medical Services

The fast and foolproof setup makes it easy to use so vital treatments can start as soon as possible. The compact design is very secure, as the small single use warmer can be attached to the patient with the adhesive next to the IV entrance and the battery can be attach to the stretcher, reducing the risk of pulling out the catheter. The light weight and small volume minimize the equipment brought into the air, while still having the capacity to warm 4 bags of cold blood (5°C) on a single charge of the power pack.

The °M Warmer System is approved for use in helicopters and airplanes fulfilling the requirements from IEC 60601-1-12:2015, DIN EN 13718-1 and RTCA DO-160 section 21.

Rapid Response Vehicles & Ambulances

In trauma situations, paramedics must act fast as minutes are crucial. The °M Warmer System has a fast and foolproof setup, making it intuitive and easy to use. Patients with substantial bleeding are at risk of hypothermia and when the body core temperature drops, the acidity in the blood increases and the blood loses its ability to coagulate making it more difficult to stop the bleeding and save the life of the patient.[1] The °M Warmer can, when administered properly, help prevent hypothermia and the complications from hypothermia.[2] Initiating blood transfusion in the pre-hospital setting has proven to reduce mortality.[3]

Hospitals

The °M Warmer System is designed to be intuitive and easy to implement, making it ideal during stressful situations in hospitals. It is small and portable and therefore fast to use when the patient arrives at the hospital and during transfer inside the hospital, making it possible to start blood transfusion at an earlier stage. The °M Warmer can, when administered properly, help prevent hypothermia and the complications from hypothermia. Finally, the °M Warmer can be used up to 72 hours making it suitable across the entire continuum of care.

Warm blood saves lives

Hypothermia is a condition where the body’s own heat production can’t match the heat loss to the environment resulting in a lowered body core temperature. Trauma patients do not die from hypothermia itself – they die of bleeding. Bleeding makes the body lose important red blood cells used to carry oxygen to the brain and other vital organs. Trauma patients with substantial bleeding are at risk of entering the deadly trauma triad of hypothermia, acidosis, and coagulopathy. This combination means that when the body core temperature drops, the acidity in the blood increases and the blood loses its ability to coagulate. Without coagulation, it is much more difficult to stop the bleeding and save the life of the patient.

Studies show that patients with admission temperatures less than 35 degrees C has significantly greater mortality.[1] This is a significant risk as studies also show that hypothermia is the most common cause of clotting disorder[2] and that approximately 57 % of trauma victims requiring immediate surgery become hypothermic in the period between injury and completion of the surgery.[3]

The American Center for Army Lessons Learned (CALL) states that 80 % of trauma deaths in Iraq and Afghanistan had a body core temperature below 34 °C. The consequence of bleeding and a BCT below 34 °C is a 2.4-fold increase of blood loss, compared to having a normal body core temperature of 37 °C.[4]

Prevention of hypothermia and early intervention are very important when it comes to temperature control of the body – waiting until arrival at the hospital could be too late.
