by Metal tubing plays a crucial role in many medical devices and instruments. Whether it’s guiding catheters and guidewires through the body or transporting fluids, metal tubing provides strength, flexibility and precision that other materials cannot match. In this article, we will explore the various types of Medical Pediatric Bed used in healthcare and why their properties make them ideally suited for many medical applications.
Stainless Steel Tubing
Stainless steel tubing is one of the most widely used types of medical tubing. It offers outstanding corrosion resistance, durability and strength. The chromium content in stainless steel gives it its rust-proof quality, making it ideal for applications where fluids will flow through the tubing. Stainless steel tubing is commonly used in devices like catheter tubes, biopsy forceps, biopsy needles and drainage tubes. It maintains its shape and integrity even with repeated bending and flexing. The material also retains its properties across a wide range of temperatures.
Some key advantages of stainless steel tubing include:
– Autoclavable – Can withstand high heat sterilization processes
– Biocompatible – Non-reactive and hypoallergenic for patient safety
– Durable – Maintains dimensional stability and kink resistance
– Cost-effective – Provides value due to low maintenance needs
While stainless steel tubing is very strong, it can also be made in small gauges and with thin walls to provide flexibility. It is offered in seamless and welded constructions. The seamless version has the highest burst strength and is best for applications requiring precision.
Nitinol Tubing
Nitinol is a nickel-titanium shape memory alloy that offers outstanding shape recovery and flexibility. These properties make nitinol tubing highly advantageous for Medical Pediatric Bed that must flex, stretch or bend during use but still resume their original shape. Some noteworthy applications of nitinol tubing include:
– Guidewires – Ability to wrap around curves and bends in the vascular system
– Catheters – Shape changing capabilities for navigating convoluted pathways
– Endoscopy – Flexible yet stiff enough for steering and positioning
– Stents – Self-expanding design that conforms to vessel walls
Besides outstanding flexibility and shape memory, nitinol tubing provides consistent performance over long periods of use without fatigue or plastic deformation. It can tolerate stresses 100 times greater than stainless steel. The biocompatible nickel-titanium alloy causes no known adverse tissue reactions either. Nitinol is more expensive than other options but is worth it for applications requiring complex deformation.
Polyimide Tubing
For medical devices where small size, thin walls and high flexibility are important, polyimide tubing can be an excellent choice. It is hardly 1/10th the thickness of stainless steel or nitinol tubing. Some of polyimide tubing’s notable characteristics include:
– Ultra thin walls – As low as 0.0001 inches or 0.0025mm
– Flexibility – Highly pliable yet kink and crush resistant
– Heat resistance – Withstands over 500°F of continuous use
– Biocompatibility – Approved for long term implantation
– Transparency – Allows fluid/component monitoring
Areas where polyimide is frequently used include guidewires, ablation catheters, drug delivery systems, microfluidic chips and neural interfaces. It offers designers much more space for other device components since the tubing itself takes up so little space. Polyimide tubing maintains its flexibility even with repeated outer sleeve placements and removals.
PTFE Tubing
PTFE or Teflon tubing provides a non-reactive, low friction surface. It has excellent chemical resistance, withstanding most acids, bases, organic solvents and disinfectants. PTFE tubing’s other notable qualities include:
– Low coefficient of friction – Helps reduce clogs and hangs
– Non-stick surface – Prevents molecule, cell and protein adhesion
– Surface hardness – Retains bore for precise fluid control
– Flexibility – Can be formed into coils and convoluted pathways
– Hydrophobic – Repels water and other polar liquids
Common medical uses of PTFE tubing are in blood pumps, hemodialysis, peristaltic pumps and inbuilt medical device tubing. It also works well as multi-lumen tubing. PTFE’s non-reactive surface makes it suitable for sensitive pharmaceutical, biotech and diagnostic applications as well. Like nitinol and polyimide tubing, it is more expensive than stainless steel and polyethylene alternatives.
Other Medical Pediatric Bed Materials
Other tubing materials used less commonly in medical devices include polyethylene, polyurethane, nylon and specialty alloys like MP35N. Each offers unique advantages for specific applications:
– Polyethylene – Inexpensive, flexible and clear for visual inspection
– Polyurethane – Elastic yet durable for flexibility under pressure
– Nylon – High tensile strength for tightly fitting parts and crimping
– MP35N – Nickel-cobalt alloy providing MRI compatibility
Designing medical devices, engineers must consider factors like biocompatibility, flexibility, strength, heat tolerance and cost to select the optimal tubing material. No single material excels in all categories, so trade-offs exist. Working closely with tubing manufacturers ensures the final design leverages each material’s strengths suitably for quality patient care.
