Intended Use: For transnasal delivery of enteral nutrition into the gastrointestinal tract. 

适用范围：用于经鼻向胃肠道引入营养液。 

“Legacy” model refers to traditional enteral feeding tube connector systems used prior to the adoption of ENFit. Legacy connectors (also  called Cath Tip, Toomey, or Christmas Tree tips) use a slip‑fit connection rather than the newer ENFit screw/locking system.  Legacy 型号指的是传统的鼻饲 / 肠营养导管连接方式，在 ENFit 连接标准推出之前广泛使用。Legacy 接头也称为 Cath Tip、Toomey 头、Christmas Tree（圣诞树式）接头，它通过插入式端口与营养 管线或注射器连接，而不是旋入式锁紧。  

TPU construction: Thermoplastic polyurethane provides softness, biocompatibility, and resistance to body fluids. TPU 管体：热塑性聚氨酯材料，柔软、耐体液腐蚀、对组织刺激低。 Radiopaque markers: Allows X‑ray confirmation of placement. X 线显影标记：管体带放射不透线或显影条，有助于定位确认。 

Multiple sizes and lengths: To suit various patients and indications. 长度及规格多样：满足不同临床体型与用途。 Optional stylet: Some versions include a flexible stylet for guided placement. 可选导丝（如带钢丝导丝）用于置管辅助。

Product Features & Advantages 产品特点及优势

1. Gravity bullet tip is fusion-bonded to the catheter shaft, avoiding the risk of detachment associated with adhesive bonding. 重力子弹头与管身熔接连接，避免粘胶连接的脱落风险； 

2. The distal 10 cm is treated with hydrophilic coating on both inner and outer surfaces, ensuring smoother insertion and reducing the risk of  clogging by enteral nutrition. 顶端做了 10 cm 内外清水涂层处理，外部进入人体更顺滑，内部营养食物不会堵塞； 

3. Dual-lumen connector with an additional port facilitates aspiration, medication administration, and sampling. 双腔转接头，多一个转接头更利于抽取，给药以及取样的操作；

4. The catheter shaft contains 20% barium sulfate, providing full-length radiopacity. 管身含有 20% 硫酸钡，管身全显影。
