What is PET Shrink Tubing and Why is it Essential for Catheter Insulation
PET heat shrink tubing makes a tight, protective cover around catheters. It helps protect sensitive parts inside. This insulation is very important for patient safety. It stops unwanted electrical and heat transfer. Medical devices use PET heat shrink tubing because it is strong. It has very thin walls and is safe for the body. The PET Shrink Tubing for Catheter Insulation works very well, as shown in the table below:
Property | Performance Indicator |
|---|---|
Tensile Strength | Very high, exceeding 20,000 PSI |
Flex Fatigue | Very high flex fatigue properties |
Electrical Insulation | Good electrical insulation |
Wall Thickness | Ultra-thin walls |
Dielectric Strength | High dielectric strength |
Biocompatibility | Compliant with USP VI and ISO 10993 |
Good insulation helps keep catheters safe. For example, the Khione catheter cools at 2.2°C per minute. It keeps the core temperature drop very low. This lowers risks like systemic hypothermia.
Catheter Model | Infusion Rate (mL/min) | Cooling Rate (°C/min) | Core Temperature Drop (°C) | Key Safety Impact |
|---|---|---|---|---|
Khione Insulative Catheter | 20–40 | 2.2 ± 2.5 | ~0.2 (average) | Improved local cooling rate, minimal core temp drop, reduced systemic hypothermia side effects, avoids fluid overload |
Hybernia Medical Catheter | 0.1–70 | 0.8 | N/A | Precise temperature control, reduces systemic hypothermia side effects, safe for cerebral tissue |
Biocompatibility and safety are always important in medical devices. This makes PET heat shrink tubing a smart choice for patient care.
