Technology and IP watch: intranasal cooling, BrainCool/ZOLL, corpuls and liquid ventilation

Strategic developments

Several 2026 technology and market signals are relevant to AIRCHILL positioning.

NeuroIntact / VCool

NeuroIntact is developing a portable intranasal gas-cooling platform. Its patent family and clinical-development activity make it relevant for future freedom-to-operate review, particularly around thermoelectric cooling, gas-path control, sensor feedback and intranasal delivery.

BrainCool / ZOLL

BrainCool continues to expand temperature-management commercialisation with ZOLL and remains an important reference platform for clinical evidence, distribution, recurring consumables and international regulatory expansion.

corpuls auryx

The new in-ear sensor platform combining temperature, pulse and oxygen saturation is strategically interesting for EMS interoperability. Established monitoring and telemedicine components may allow AIRCHILL to integrate mature external technology rather than reinvent every subsystem.

Orixha / LunCoLive

Total liquid ventilation remains a technologically distinct route to rapid cooling. Its complexity and clinical-development path make it both a useful comparator and a reminder that respiratory heat exchange can be pursued through very different architectures.

IP implication

AIRCHILL’s granted patent position does not remove the need for product-level freedom-to-operate analysis. Claim charts should be maintained against emerging patent families, especially where competitors combine cooled gas, airway delivery, thermoelectric hardware, feedback control and temperature sensing.

Product-strategy implication

Differentiation should remain focused on:

  • very early use in time-critical care,
  • integration with transport ventilation,
  • controlled respiratory heat exchange,
  • modular use of established monitoring/OEM components,
  • a clearly measured safety and clinical-validation pathway.

Competitor references are provided for strategic monitoring and do not imply infringement, invalidity or freedom to operate.
