Application of silicone rubber in medical field

The silicone rubber is divided into heat vulcanized type (HTV) and room temperature vulcanized type (RTV), among which room temperature vulcanized type is divided into polycondensation reaction type and addition reaction type.High temperature silicone rubber is mainly used in the manufacture of various silicone rubber products, while room temperature silicone rubber is mainly used as adhesives, filling materials or molds.

Thermal-vulcanization type has the largest dosage.Thermally-vulcanized silicone rubber can be divided into methyl silicone rubber (MQ), methyl vinyl silicone rubber (VMQ) (maximum dosage and product brand), methyl vinyl phenyl silicone rubber PVMQ (low temperature resistance, radiation resistance).There are other eye silicone rubber, fluorosilicon rubber and so on.

Among many kinds of synthetic rubber, silicone rubber is one of the best.It has tasteless and non-toxic, not afraid of high temperature and resist the characteristics of cold, in the temperature range of -90~+300 degrees Celsius, still do not break the original strength and elasticity.Silicone rubber also has good electrical insulation, oxygen resistance and aging resistance, light resistance and aging resistance, mildew resistance, chemical stability and so on.Because of these excellent properties, silicone rubber has played an important role in modern medicine.In recent years, a variety of silicone rubber medical supplies have been successfully trial-produced by hospitals, scientific research units and factories.

Silicone rubber anti-noise earplug: comfortable to wear, can be a good noise barrier, protect the eardrum.

Silicone rubber fetal head attractor: easy to operate, safe to use, can be deformed according to the size of the fetal head, the fetal scalp will not be sucked when attracting, can avoid scalp hematoma and intracranial injury and other disadvantages, can greatly reduce the pain of pregnant women in dystocia delivery.

Silicone rubber artificial blood vessels: with special physiological functions, can be done with the human body "intimate", the body does not reject it, after a certain period of time, will be with the human body tissue complete case stability is extremely good.

Silicone rubber tympanic membrane patch: thin and soft, good finish and toughness.It is an ideal material for repairing eardrum with simple operation and good effect.

In addition, there are silicone rubber artificial trachea, artificial lung, artificial bone, silicone rubber duodenal tube, and other functions are very ideal.

In the field of cosmetic and plastic surgery, silicone rubber products are also widely used, such as silicone nose bridge, silicone breast, etc.

With the progress and development of modern science and technology, silicone rubber will have a broader development prospect in medicine.
