详细描述：

本产品是一款高品质的兼容替代血氧（SpO₂）延长线，专为 Nellcor OxiMax 14针加密接口的监护仪及血氧模块设计。一端为 14针公头，另一端为蓝紫色大母头，线长 2 米，用于延长血氧传感器与监护仪之间的距离，为临床监护提供更大的操作灵活性和患者舒适度。

核心特点：

1. 精准兼容： 专为 Nellcor OxiMax 14针加密接口设备量身打造，内置信号直通设计，确保与 Nellcor 系列监护仪及血氧模块无缝连接，信号传输稳定可靠。

2. 蓝紫色大母头： 患者端采用标准的蓝紫色大母头接口，完美适配 Nellcor OxiMax 系列血氧传感器（包括包裹式、粘附式、可重复使用式等），符合原厂色彩识别体系，便于临床快速识别和匹配。

3. 加密协议支持： 完全兼容 Nellcor OxiMax 数字信号协议，支持传感器信息读取（如型号、使用次数等），确保血氧监测的准确性和安全性。

4. 耐用可靠： 连接器尾部采用注塑加固工艺，抗拉耐折，经过严格的插拔寿命测试和拉力测试，确保长期使用不断裂、不松脱。插针采用耐腐蚀磷铜或镀金材质，保证良好的导电性和抗氧化性。

5. 广泛兼容： 兼容所有采用 Nellcor OxiMax 14针技术的监护仪及血氧模块，如 Medtronic、Covidien 等品牌的系列监护仪。

6. Detailed Description：

   This is a high-quality, compatible SpO₂ extension cable designed specifically for Nellcor OxiMax 14-pin encrypted interface monitors and oximetry modules. Featuring a 14-pin male connector on one end and a standard purple large female connector on the other, this 2-meter cable extends the distance between the SpO₂ sensor and the monitor, offering greater clinical flexibility and patient comfort.

7. Key Features：

   1. Precise Compatibility： Specifically engineered for Nellcor OxiMax 14-pin encrypted devices, featuring signal pass-through design to ensure seamless connection with Nellcor series monitors and OEM oximetry modules for stable signal transmission.

   2. Purple Large Female Connector： The patient end features the standard purple large female connector, perfectly compatible with the full range of Nellcor OxiMax SpO₂ sensors (including wrap-type, adhesive, and reusable sensors). The color-coded design aligns with the original manufacturer's identification system, facilitating rapid clinical recognition and matching.

   3. Encryption Protocol Support： Fully compatible with the Nellcor OxiMax digital signal protocol, supporting sensor information reading (e.g., model, usage count) to ensure accuracy and safety of oxygen saturation monitoring.

   4. Durable & Reliable： The connector strain relief is reinforced with over-molding for excellent tensile and flex resistance. It undergoes rigorous insertion cycle and pull force tests to ensure long-term durability without breakage or loosening. Pins are made of corrosion-resistant phosphor bronze or gold-plated material for excellent conductivity and oxidation resistance.

   5. Broad Compatibility： Compatible with all patient monitors and oximetry modules featuring Nellcor OxiMax 14-pin technology, including Medtronic, Covidien, and other major brands.
