2. Blue silica gel contains a small amount of cobalt chloride, which is potentially toxic. Contact with food and inhalation should be avoided. In case of poisoning, you should seek medical attention immediately.
Extended data:
Medical silicone is a biological material widely used in cosmetic surgery, including liquid silicone oil, jelly-like silicone oil, foam silicone sponge and elastic solid silicone rubber, among which solid silicone rubber is the most widely used.
1, characteristics: silicone rubber has good biocompatibility, no irritation, no toxicity, no allergic reaction to human tissues and little rejection reaction; It has good physical and chemical properties, and can maintain its original elasticity and softness when it comes into contact with body fluids and tissues, and is not degraded. It is a fairly stable inert substance. It can resist high temperature and disinfect. Convenient processing and molding, easy processing, carving and molding, and convenient use.
2. Classification and use: Silicone rubber can be divided into thermal vulcanized silicone rubber and room temperature vulcanized silicone rubber. Thermal vulcanized silicone rubber can be made into products with different hardness, which is the most commonly used one in clinic and can be carved into various shapes in advance. Such as: nose prosthesis, artificial mandible, skull patch, breast prosthesis, auricle or facial prosthesis supporting mandible, artificial joint, artificial testis, etc.
Room temperature vulcanized silicone rubber. At room temperature, the curing process of silicone oil is completed under the action of catalyst. Before it is still liquid and not hardened, it is injected into the required part and filled and molded according to the form of local defects. However, this usage has many complications and has been stopped.
