In-depth application of TPU materials in the medical industry
1. Medical Catheters
TPU is the preferred material for manufacturing medical catheters, such as infusion tubes, urinary catheters, respiratory tubes, and cardiac catheters, due to its softness and elasticity. These properties allow catheters to be inserted and removed without damaging internal tissues, while its mechanical stability and biocompatibility meet the stringent requirements of medical-grade products. For example, TPU-based gastroscope tubing ensures smooth operation during examinations owing to its high strength and flexibility, with no toxic side effects, fulfilling the high-performance demands of fiber-optic gastroscopy. Additionally, TPU endotracheal tubes enhance patient comfort and mobility while effectively shielding against radiation, making them indispensable in modern healthcare.
2. Implants and Artificial Organs
TPU excels in the field of implants and artificial organs. As an ideal material for artificial blood vessels, TPU offers excellent blood compatibility, durability, and reduced immune reactions or thrombosis risks during blood contact, ensuring long-term structural and functional stability. TPU is also used in components of cardiac assist devices, such as pump housings and seals. These parts must withstand high-intensity blood flow and prolonged patient activity, and TPU’s high strength, wear resistance, and elasticity guarantee their stability and sealing integrity, enhancing the safety and reliability of cardiac assist systems.
3. Medical Films and Dressings
Traditional PE and PVC films, while widely used in medical protection, suffer from poor breathability and patient discomfort. In contrast, TPU medical films demonstrate superior advantages in wound dressings, surgical protective films, and gloves due to their softness, skin-friendliness, elasticity, strong moisture permeability, and waterproofing. TPU films prevent intraoperative detachment and inhibit pathogen transfer, significantly reducing infection rates. Furthermore, TPU foam, with its breathability and skin-regeneration properties, is widely used in artificial skin and dressings to accelerate epidermal growth, retain moisture and electrolytes, and minimize bacterial infection risks.
4. Medical Protective Equipment
TPU plays a vital role in medical protection. For instance, TPU protective suits and isolation barriers provide Level 4 or higher protection, effectively blocking viruses and bacteria while maintaining breathability and durability. These products have been critical during pandemics, safeguarding healthcare workers.
5. Drug Delivery Systems
By adjusting TPU’s molecular structure and porosity, precise controlled drug release can be achieved, enhancing bioavailability and therapeutic efficacy. This positions TPU as a promising material for advanced drug delivery systems.
6. Wearable Medical Devices
TPU is utilized in wearable medical devices, such as electronic patches and smart wristbands, which monitor patients’ physiological indicators in real time, providing essential data for diagnosis and treatment.
