What is RUSCHELIT?
RUSCHELIT is the registered name for the PVC plastic employed
by RUSCH in the manufacture of medical products. RUSCHELIT"
is a compound of PVC and physiologically innocuous plasticizers and
stabilizers. The range of surface textures extends from extremely shiny
to velvet-like. Depending on the purpose, the material can be made harder
or softer, opaque and colored or transparent. Devices made of RUSCHELIT'
are therefore provided with the right degree of stiffness, flexibility
and resistance to kinking. RUSCHELIT materials, as well as ERU
and ERUPLAST materials, are tested according to USPXXIII, Class
VI and IS0 10993 / EN 30993. They are non-toxic. Depending on the purpose,
RUSCHELIP can also be made radiopaque by the addition of suitable substances.
On account of its properties, RUSCHELIT is also suitable for the
manufacture of especially flexible devices, for example those armored
with an embedded stainless steel spiral. The material becomes more pliable
when warmed by contact with the body, so that the device adapts well
to the prevailing anatomical situation.
What is soft rubber?
RUSCH soft rubber is made from natural rubber and medically innocuous
additives (including mineral filling materials). For this reason, this
type of rubber is also known as mineralized soft rubber. Its main characteristics
are optimum stiffness, a high resistance to kinking, and a high degree
of flexibility. Further advantages are its X-ray detectability and electrical
conductivity. RUSCH soft rubber is high-performance material.
Devices made of this material can be steam-sterilized at 121°C or
134°C many times (usually twenty times or more), which is of economic
significance. In contrast to soft rubber, RUSCH ROBUSTA is a particularly
resistant mixture of natural rubber with a higher Shore hardness.
CAUTION
Latex and rubber instruments must not be used in sensitized patients
with allergic reactions to materials contained in these products.
What is SILKOMED?
SILKOMED is the registered name for the silicone elastomer used
by RUSCH in the manufacture of medical devices. It is made chemically
from inorganic materials.
A high-polymer product is obtained by polycondensation of the monomeric
basic substances. This product has rubber-like, elastic properties as
a result of chemical cross linking. SILKOMED is characterized
by its physiological innocuousness (implantability) and its resistance
to ageing. SILKOMED is resistant to oxygen, ozone, UV light and
temperatures of up to 200°C. SILKOMED may be steam -sterilized
without restrictions at 121°C or 134°C and does not contain
any substances which can be extracted by water or tissue fluids. SILKOMED"
is tested according to USPXXIII, Class VI and IS0 10993 / EN 30993 and
is non-toxic. A special advantage is its strong tissue and water repellent
property which virtually eliminates incrustation with blood or tissue.
What is SILKOLATEX®?
SILKOLATEX® is the registered trade name for a latex/silicone compound
which is protected by patents throughout the world and is manufactured
only by RUSCH. It is an anhydrous, chemically cross-linked coagulum
obtained from natural rubber latex which has been refined with a high-molecular
weight silicone compound in order to improve its properties. Silicones
- or, scientifically, organic silicon compounds - are substances with
particularly advantageous properties: largely resistant to both temperature
and ageing, physiologically innocuous and usually oil or wax-like. One
of their most interesting properties is that they are water repellent
or hydrophobic. This prevents deposits, in particular of water-soluble
or water-containing adhesive substances in the widest sense (for example
blood, blood clots, serum, urine, etc.). Experience has shown that these
body products are the cause of the well-known phenomenon of incrustation,
especially in conjunction with crystallizing substances in the urine.
How SILKOLATEX® devices turn a chemical disadvantage into an advantage.
Organic silicon compounds are incompatible with many organic substances.
They separate and they "sweat". This property is made use
of in SILKOLATEX® devices: The outer surface and also the inner
surface of the lumen are constantly covered with a thin layer of silicone
which is automatically renewed even after being washed off with surface-active
detergents; it is "sweated" out of the latex material.
CAUTION
Latex and rubber instruments must not be used in sensitized patients
with allergic reactions to materials contained in these products.
