Connector

Two connector options are available to accommodate feeding tubes or infusion equipment, providing healthcare professionals with greater flexibility to meet different clinical needs.
✦ Connection System

Precise Positioning

X-ray Imaging

The nasogastric tube incorporates radiopaque X-ray markers for reliable tube-position visualization. Depending on customer requirements, we can provide single-barium, double-barium, triple-barium, or fully radiopaque options. The tube tip is equipped with a high-barium-content radiopaque marker to provide clear imaging and enhanced visibility under X-ray, making tube placement easier to confirm.
✦ Imaging & Positioning

Comfort & Safety

Hydrophilic Coating

The distal tip of the tube features a hydrophilic coating that forms a highly lubricious hydrogel layer when exposed to water. This significantly reduces friction between the tube and the gastrointestinal mucosa during insertion, helping minimize insertion-related discomfort. Unlike conventional lubrication with paraffin oil or petroleum jelly, the hydrophilic coating helps avoid the risk of secondary contamination associated with external lubricants.
✦ Surface Technology

Proprietary Innovation

pH-Sensitive Guidewire

The nasogastric tube is equipped with a grafted pH-sensitive guidewire, featuring patented technology and a pioneering domestic design. After insertion, the tube position can be preliminarily assessed without aspirating gastric contents. Simply remove the guidewire and compare the color change of the integrated pH test paper. The guidewire is made of 304 stainless steel and incorporates a precision spring. Through a specialized surface-treatment process, it achieves an optimized balance of flexibility and rigidity, providing smooth insertion and excellent conformability. The guidewire tip features a smooth, rounded design to help prevent scratching or damaging the inner wall of the tube.

Q Is this nasogastric tube disposable or reusable? A Unlike PVC tubes which usually need replacement every 7 days, TPU tubes are designed for medium-to-long-term use and can typically remain in place for up to 30 days. This reduces the frequency of re-insertion and minimizes patient trauma. Q Is TPU nasogastric tube safer than other materials for nasogastric tubes? A Yes, TPU (polyurethane) nasogastric tube is biocompatible, flexible, and resistant to kinking. It is less likely to cause irritation compared to PVC or silicone tubes, making it safer for long-term use. Q Can this nasogastric tube be used for feeding and gastric decompression? A Yes, TPU nasogastric tubes with guide wire are suitable for both enteral feeding and gastric decompression, depending on the size and lumen design of the tube. Q Is the TPU nasogastric tube radiopaque for X-ray confirmation? A Yes, our TPU Nasogastric tubes feature a full-length radiopaque stripe or tip. This allows for clear visualization under X-ray or fluoroscopy, ensuring healthcare providers can accurately verify the tip's location before starting feeding. Q How to choose the correct size for a nasogastric tube ? A Choose based on the patient’s age, weight, and clinical condition. Adult tubes are usually 12–18 Fr, while pediatric or neonatal tubes are smaller. Always follow medical guidelines or consult healthcare professionals.
