Passivation and Medical Device Cleaning

Ultra
Pass® passivation - Is to produce high surface chromium levels
creating the best corrosion resistant passive surface.
In physical
chemistry and engineering, passivation is the material getting
passive without being affected by environmental factors such as air
or water. It is a technique that uses a light coat of material like
metal oxide for creating a shell against corrosion. It helps to
strengthen and preserve the appearance of metallic's.

Passivation
is such a procedure that occurs in certain conditions and used
in microelectronics for enhancing silicon. The procedure is done on
materials like silicon, aluminum, stainless steel and nickel to
make them more passive and resistant to corrosion.
Passivation is usually done by creating a
surface film that causes the surface to lose its chemical
reactivity. This causes the metal to corrode at much lower rate
than its usual rate. In case of stainless steel, passivation occurs
when free iron, oxide scale, rust, iron particles, metal chips and
other non-volatile deposits start affecting the stability of the
surface, the operation of a part, component or system contaminating
the process fluid.
In the passivation of silicon, aluminum,
stainless steel and nickel, the materials may spontaneously form a
chemically inactive surface when exposed to air or other
environments containing oxygen. Most often, passivation removes
iron compounds from the surface of the material using a chemical
dissolution that may contain citric acid solution.
The field of medical science uses various
medical devices that are crucial to diagnose, monitor or treat
different conditions. The devices follow rigorous safety standards
and ensure the safety of the patients. Usually, the medical devices
used may be categorized as

·

Diagnostic. These
are used to identify the disease and include ultrasound, MRI,
X-ray, PET and CT scanners.

·

Therapeutic. These
help the patients during and after the surgery and include lasers,
infusion pump and LASIK devices.

·

Life support. These
help a patient to maintain their body functions and include
cardiovascular devices, ventilators, dialysis devices, ECMO and
anesthetics.

·

Monitors. These
include EEG, ECG, etc. that help the surgeons to evaluate the state
of the patient by keeping account of their blood pressure and
pulses.

·

Medical laboratory.
These devices are used to analyze urine, blood and
genes.
It is important to carry out

medical device
cleaning
so that the devices provide long-term service and do not
spread infection. Devices that are to be reused should be
disinfected by cleaning them with a disinfectant solution. This
helps to remove the smallest of the contaminant quantities. In
case, of larger medical devices, one may take the services of
service centers who specialize in such procedures.
