The application of silicone in medical technology

With the increasing attention of each country to food safety and medical care, especially the human body, food and medical-related silica gel products have made strict requirements.

After decades of clinical application, silicone as a medical material has been recognized by the medical community, and more and more widely used. Many companies regard medical silicone rubber as the main goal of development, and medical silicone has made great progress.

Silicone besides can meet the basic requirements of medical polymer materials, but also has heat, cold resistant, non-toxic, resistance to aging, minimal response to human tissue, good physical and mechanical properties, etc, to become the typical medical polymer materials, widely used in the field of medical and health care, biomedical engineering, in the current numerous medical polymer materials, silicone rubber, either in quantity or dominant species.

With the continuous development of medical technology, liquid silica gel products are increasingly used in medicine.Nowadays, medical silicone products such as medical silicone airbags, medical silicone tubes, silicone rubber bands and silicone pads have been put into the market, and medical-grade silicone has been put into medical use.

In the medical industry, in order to meet the increasing medical demand, the research direction of liquid silica gel mainly focuses on three aspects: surface modification, blending modification and application research.The material has good coagulability, good stability, good clinical use, no allergic reaction, product stability and performance are higher than ordinary silica gel and food grade silicone.

Catheter: Medical catheter is the fastest developing and most widely used product in medical silicone rubber products.According to the use can be divided into in vitro and in vivo, in vitro is mainly all kinds of pump pipe, such as artificial heart-lung machine pump pipe, with a variety of equipment connection pipe, infusion pipe;All kinds of cannula, catheter and drainage tube are used in the body.At present, the development trend of medical catheters used in human body is miniaturization, thin-walled, multi-cavity and multi-function of one tube.Especially for the catheter in the body, whether long-term or short-term use, silicone rubber material, the advantages of the catheter is unmatched by other materials.

Cerebral surgery products: used in cerebral surgery of silicone rubber products mainly include: artificial skull, titanium silicon composite repair materials, hydrocephalus six device, ventricle drainage tube, artificial dura mater, the current domestic developed using silicone and nylon fabric made of artificial dura mater, can be used to repair traumatic dural defects, repair due to the removal of the tumor in the epidural or Kitty infiltration area caused by the dura mater or defect of stiff backbone film, etc.

Otolaryngology products: Silicone rubber products used for ENTs include: artificial nose, artificial chin, mandible, artificial ear, artificial throat, otitis media ventilation tube, lacrimal passage probe, lacrimal plug, nostril support, snoring device, Nasal hemostatic balloon, wave tube of artificial ventilator, tracheotomy tube, etc. At present, silicone rubber has been widely used in plastic surgery and repair surgery, and can repair various parts of the face, internal organs, chest, joints, etc.

Cardiac Surgery Products: Silicone rubber products used in cardiac surgery mainly include pump tubes for extracorporeal circulation machines, chest drainage tubes, artificial lung silicone membranes, artificial heart spherical mitral valves, etc.

Digestive system products: silicone stomach tube, duodenal tube, double coelenteron casing, nutrition tube, gastric tube decompression, gastrostomy tube fistula, stomach tube, enema, etc., before these products mainly USES PVC material, with silicone rubber production cost is reduced, and the more ideal silicone rubber products, softness and elasticity, so at present in China has started to replace polyvinyl chloride (PVC) products.

Abdominal surgery and reproductive system products: silicone rubber products used in abdominal surgery mainly include: peritoneal dialysis tube, abdominal drainage tube, T tube, Y tube, TY tube, capillary drainage tube, porous drainage tube, negative pressure drainage device , Anti-adhesion membrane, etc.; it has a wide range of applications in the reproductive system, mainly including various urinary catheters, fistulas, penile prostheses, artificial testes, fetal suction devices, uterine heat ball therapy devices, silicone rubber IUDs, Implanting contraceptive devices under the skin.

As people pay more and more attention to health, the market capacity of medical devices is becoming larger and larger, and the demand is also growing rapidly.In view of the inherent medical characteristics of medical silica gel, the application scope of medical silica gel is constantly expanding, and the medical silica gel products have high technical content, high added value and considerable economic benefits. Therefore, the development and industrialization of medical silica gel products has a broad prospect.
