Manufacturing method of hydrogel artificial breast prosthesis

Abstract

A production method of hydrogel artificial breast includes the following steps: using high polymer resin with polyvinyl alcohol as main material as raw material, placing it in distilled water, stirring and heating to obtain a solution whose concentration is 5-15 wt%, filtering and fillint it into breast-like silicon rubber bag which is then sealed, then encasing the sealed silinone rubber bag in a package with breast-like mould frame, irradiating with Co-60 gamma ray at normal temp. in the air, and its radiation absorbed dose is 10-30 KGy. Said invention is simple in production process, low in cost, has no pollution, the form of said invented artificial breast is beautiful, and the said artificial breast possesses high elasticity and good biological compatibility.

Description

【Technical field】 [0001] The invention relates to an artificial medical prosthesis, in particular to a medical biocompatible hydrogel artificial breast prosthesis and a manufacturing method thereof. 【Background technique】 [0002] At present, the artificial breast prosthesis commonly used in medical treatment includes silicone gel prosthesis and saline capsule prosthesis. The biggest advantage of the silicone gel prosthesis is that the feel and shape are realistic, but the silicone gel breast prosthesis and its manufacturing method have the following disadvantages : 1. The silicone rubber capsule of the silicone gel breast prosthesis and the filler silicone gel in it are the same type of material with similar structure, so the two will be compatible, that is, the capsule gradually dissolves with the gel of the filler. Combined, the silicone gel slowly seeps out of the capsule, and the capsule wall gradually swells, loosens, thickens, and decreases in tensile strength under t...

Problems solved by technology

[0002] At present, the artificial breast prosthesis commonly used in medical treatment includes silicone gel prosthesis and saline capsule prosthesis. The biggest advantage of the silicone gel prosthesis is that the feel and shape are realistic, but the silicone gel breast prosthesis and its manufacturing method have the following disadvantages : 1. The silicone rubber capsule of the silicone gel breast prosthesis and the filler silicone gel in it are the same type of material with similar structure, so the two will be compatible, that is, the capsule gradually dissolves with the gel of the filler. Combined, the silicone gel slowly penetrates out of the capsule, and the capsule wall gradually swells, loosens, thickens, and decreases in tensile strength under this penetration, and is finally dissolved, so the life of the prosthesis is short

2. Once the capsule is broken, the silicone gel will leak out and adhere to the surface of human tissue, which will slightly stimulate the tissue and cannot be degraded in the body

3. Silicone gel breast prosthesis cannot be penetrated well by X-rays, which brings difficulties to chest fluoroscopy for disease diagnosis

4. There is waste gas emission during the production process of silicone gel breast prosthesis, which will pollute the environment

5. The production process of silicone gel breast prosthesis is complex, high cost and expensive

The main disadvantage of the saline bladder prosthesis is poor hand feeling; there is high atomic number chlorine in the saline bladder, which affects the X-ray examination of the chest; mildew is very easy to occur in salt water, which poses a potential threat to the body; the saline bladder is also very Easy to rupture, once ruptured, the breast will shrink quickly
