### **Intravenous Infusion Set Product Introduction**
#### **I. Product Overview**
The intravenous infusion set is a medical device used for directly administering sterile medicinal solutions, blood products, or nutritional fluids into a patient's veins. It is one of the most widely used basic consumables in modern clinical therapy. By establishing a controlled venous access pathway, it enables safe, continuous, and accurate fluid infusion, serving as a core tool in emergency care, surgical procedures, infection treatment, nutritional support, and routine infusion nursing.
#### **II. Product Structure and Functional Features**
1. **Precision Structural Design**
- **Puncture Device**: Utilizes medical-grade stainless steel intravenous needles or safety indwelling needles with specially polished tips for smooth insertion and reduced tissue trauma.
- **Flow Rate Control Device**: Equipped with a precise roller-type or clamp-type flow regulator to accurately adjust infusion speed (drops per minute), meeting diverse therapeutic needs.
- **Filtration System**: Includes a built-in 15μm solution filter that effectively blocks particles, air bubbles, and impurities, lowering the risk of infusion reactions.
- **Venting Device**: The infusion bottle piercer contains an air filter membrane (0.2μm hydrophobic membrane) to balance internal pressure and prevent contamination.
2. **Safety and Compatibility**
- **Sterile and Pyrogen-Free**: Produced under fully sterile conditions in compliance with the ISO13485 quality system, with endotoxin levels below pharmacopoeia standards.
- **Material Safety**: Tubing is made of medical-grade PVC, TPE, or silicone-transparent, flexible, and free from phthalates, ensuring excellent biocompatibility.
- **Anti-Reflux Design**: Some models are equipped with check valves or anti-reflux clips to prevent blood backflow and tube blockage.
3. **User-Oriented Functional Configurations**
- **Drug Injection Port**: Features a Y-type or three-way injection port for mid-infusion drug administration, avoiding repeated punctures.
- **Precision Graduations**: The drip chamber and tubing have clear volume markings for real-time monitoring of infusion volume.
- **Adhesive Fixation Wing**: Aids in securing the needle device, reducing slippage risks, and enhancing patient comfort.
#### **III. Core Advantages**
- **Accurate Infusion**: Flow rate error ≤ ±5%, suitable for precision infusion scenarios such as pediatrics and chemotherapy.
- **Infection Control**: Fully closed system design reduces the probability of iatrogenic infections.
- **Ease of Operation**: Pre-assembled and ready to use, minimizing procedural steps for nursing staff.
- **Wide Compatibility**: Compatible with various infusion bottles, bags, and infusion pumps.
#### **IV. Clinical Application Scenarios**
- **Emergency Rescue**: Rapid establishment of venous access for resuscitative fluids or emergency medications.
- **Long-Term Therapy**: Periodic chemotherapy, nutritional support for chronic conditions (e.g., diabetes, oncology).
- **Perioperative Care**: Intraoperative fluid replacement, anesthesia delivery, and postoperative pain management.
- **Special Populations**: Precision infusion management for pediatric and geriatric patients.
#### **V. Technical Parameters**
- **Models**: Adult/Child/Blood Transfusion-specific types
- **Infusion Speed**: Standard 0–120 drops/minute; precision models support fine adjustment down to 0.1 mL/h.
- **Filter Pore Size**: 15μm (standard), 5μm (precision filtration type)
- **Shelf Life**: Sterile packaging, valid for 3 years.
#### **VI. Usage Precautions**
1. Before use, inspect packaging integrity, expiration date, and fluid clarity.
2. Strictly adhere to aseptic techniques, with regular disinfection and replacement of puncture sites.
3. Select tubing materials appropriate for the drug properties (e.g., osmolarity, pH).
4. Closely monitor patient response during infusion to prevent air embolism or fluid overload.
#### **VII. Quality Certifications**
The product complies with China's "Regulations on the Supervision and Administration of Medical Devices," European CE certification, and U.S. FDA standards. It has passed multiple quality control verifications, including biosafety testing (GB/T16886) and particulate contamination testing.
