CAP-One

Product catalog summary

Introduction
The document discusses the advanced miniaturization of an infrared absorption spectroscopy system, focusing on the cap-ONE CO2 sensor, which is a new class of ultra-compact sensors designed for respiratory management.

Specifications

The sensor weighs only 4 grams.
It has IPX7 protection against water immersion.
It can withstand a 1.22-meter drop, meeting MIL-STD-810F transit drop requirements.

System Design

An elliptical mirror focuses infrared light, which is split by a half mirror into two beams for signal and reference detection.
Photo detector A detects the reference beam, while Photo detector B detects the signal beam.

Innovations

The sensor uses an anti-fogging membrane that forms a smooth layer of water, allowing accurate CO2 measurement without a heater, reducing power consumption and weight.
This design is reliable even under high humidity conditions and is safe, preventing burn injuries.

Applications

The sensor is suitable for both intubated and non-intubated patients.
It is durable enough for use in harsh environments.

Conclusion
The cap-ONE CO2 sensor offers a reliable and accurate solution for respiratory management, with advanced features that enhance its performance and safety in various medical settings.

The Optimal Capnography Solution for Respiratory Management Infrared light Airway adaptor with anti-fogging membrane Normal membrane Uneven droplets of water Droplets of water cause uneven reflection and refraction of light which causes inaccurate CO 2 measurement. Traditional CO 2 sensors eliminate the water droplets with a window heater. Antifogging membrane Infrared light passes through a transparent film with a unique anti-fogging membrane Infrared light Even layer of water Nihon Kohden’s anti-fogging membrane forms a smooth layer of water which allows accurate CO2 measurement with no heater....
