Medical tubing and connectors are essential in healthcare. They transport fluids, deliver oxygen, and support medical devices. Medical injection molding produces these parts with high precision. Mold makers design molds for durability, flexibility, and sterility.
Importance of Medical Tubing and Connectors
1. Essential for Patient Care
Medical tubing delivers medication, fluids, and gases. Connectors ensure a secure, leak-free fit.
2. Prevents Contamination
Sterile tubing and connectors protect patients from infections.
3. Supports Life-Saving Equipment
They are used in ventilators, IV lines, dialysis machines, and more.
4. Ensures Consistent Performance
Medical-grade plastics maintain strength, flexibility, and chemical resistance.
5. Meets Strict Medical Standards
Each part must comply with FDA and ISO requirements.
Common Applications of Medical Tubing and Connectors
1. Intravenous (IV) Tubing
IV tubing delivers fluids, medications, and nutrients. It must be flexible and kink-resistant.
2. Catheter Tubing
Catheters help drain fluids and assist in surgeries. They must be soft and biocompatible.
3. Respiratory Tubing
Oxygen tubes and ventilator hoses deliver air to patients. They require precision to ensure airflow.
4. Dialysis Tubing
Dialysis machines use tubing to filter blood. It must be durable and chemical-resistant.
5. Feeding Tubes
These tubes provide nutrition to patients who cannot eat normally. They must be safe for prolonged use.
6. Surgical Suction Tubing
Used to remove fluids during surgery. It must be strong and flexible.
7. Luer Lock and Quick Connectors
These connectors ensure secure attachment between tubes and devices.
8. Blood Collection Tubes and Ports
Used in diagnostic testing and blood transfusions. They require airtight seals.
Materials Used in Medical Injection Molding for Tubing and Connectors
1. Polyvinyl Chloride (PVC)
PVC is flexible, durable, and resistant to chemicals. It is used in IV and respiratory tubing.
2. Silicone
Silicone is soft, biocompatible, and heat-resistant. It is used in catheters and surgical tubing.
3. Polyurethane (PU)
PU is flexible and strong. It is used in catheter and wound drainage tubes.
4. Polyethylene (PE)
PE is lightweight and chemical-resistant. It is used in feeding tubes and dialysis tubing.
5. Thermoplastic Elastomers (TPEs)
TPEs provide flexibility and durability. They are used in medical tubing seals and gaskets.
6. Polycarbonate (PC)
PC is clear and impact-resistant. It is used in rigid connectors and blood collection ports.
