A kind of personalized silica gel equivalent compensation body membrane and preparation method thereof

Abstract

The invention discloses a personalized silicone rubber equivalent compensation body membrane and a preparation method thereof. The method comprises the following steps: collecting body surface data of a patient through three-dimensional laser scanning and generating a three-dimensional digital model of the patient; inputting magics software and obtaining a compensation body membrane digital model; obtaining a digital model of a required mould through model design based on the digital model of the compensation body membrane at the lesion place of the patient; carrying out printing to obtain the mould of the compensation body membrane; taking a certain amount of liquid silicone rubber, mixing and stirring A and B components, and then, carrying out vacuumizing to discharge air; and injecting the liquid silicone rubber obtained after vacuumizing into the body membrane mould, and carrying out heat preservation and vulcanization to obtain the silicone rubber equivalent compensation body membrane. The addition-type liquid silicone rubber is high in biocompatibility with human skin and is soft in material; serving as the material of radiotherapy compensation body membrane, the silicone rubber is fit to the skin well, and the radiotherapy compensation effect is good; body-feel comfort level of the patient is greatly improved; and meanwhile, the silicone rubber equivalent compensation body membrane in any thickness can be manufactured according to clinical demands.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a personalized silica gel equivalent compensation film and a preparation method thereof. Background technique [0002] Radiation build-up effect: In the radiation therapy process, the area from the surface to the maximum dose depth is the dose build-up area, and the radiation dose in this area increases with the increase of depth. Due to the existence of the built-up effect, for superficial tumors such as breast cancer, skin, etc., in order to increase the skin surface dose, modern tumor radiotherapy uses tissue compensation glue (also called dermal filler, tissue equivalent membrane) to increase the skin dose and maximize the dose. Skin and subcutaneous tissue dose, reduce deep tissue such as lung dose, etc. The depth of ray build-up is generally 3-20mm under the skin. According to experience, the thickness of the compensation body membrane selected for clin...
