这是一款兼容的双通道（双传感器）体温探头，专为 Fisher & Paykel（斐雪派克）MR850、MR810 等呼吸湿化治疗仪设计。它采用 6 针圆形连接器，在一根电缆上集成了两个独立的温度传感器，可同时监测两个关键温度点（如气道温度和皮肤温度）。其 "双定位" 校准设计确保了在关键治疗温度范围（如 37°C 和 40°C）附近具备高精度测量能力，从而在高流量氧疗或有创通气过程中保障患者安全。本产品是原厂 Fisher & Paykel 900MR869 探头可靠且高性价比的替代选择。

This is a compatible dual-channel (dual-sensor) temperature probe designed for Fisher & Paykel respiratory humidification systems, such as the MR850 and MR810 models. It features a 6-pin circular connector and integrates two temperature sensors in one cable assembly, enabling simultaneous monitoring of two critical temperature points (e.g., airway temperature and skin temperature). The "dual fixed-point" calibration ensures high accuracy around key therapeutic temperature ranges (such as 37°C and 40°C) for optimal patient safety during high-flow therapy or invasive ventilation. This product is a reliable, cost-effective alternative to the OEM Fisher & Paykel 900MR869 probe.

1. 双通道设计：电缆包含两个温度传感器，通常一个用于测量气道端（Y型接口处）的气体温度，另一个用于测量患者皮肤温度。这为湿化治疗提供了双重安全保障。

2. 精准定位："双定位"（Dual fixed-point）意味着传感器在关键的临床温度点（如体温和气道安全上限）经过精确校准，确保反馈给湿化器的温度数据准确，从而自动调整加热功率。

3. 广泛兼容：常与 MR850、MR810 等主流湿化器配合使用，是高流量氧疗、无创及有创通气治疗的常用配件 

Dual-Channel Design:
The cable integrates two temperature sensors — one typically used to measure gas temperature at the airway (at the Y-piece), and the other to measure patient skin temperature. This provides dual safety assurance for humidification therapy.

Dual Fixed-Point Calibration:
"Dual fixed-point" means the sensors are precisely calibrated at critical clinical temperature points (such as body temperature and airway safety limits), ensuring accurate temperature data is fed back to the humidifier for automatic adjustment of heating power.

Broad Compatibility:
Commonly used with mainstream humidifiers such as the MR850 and MR810, it is an essential accessory for high-flow therapy, non-invasive ventilation, and invasive ventilation.
