Light artificial breast and preparation method thereof

Abstract

The invention discloses a light artificial breast and a preparation method thereof. The light artificial breast includes a silica-gel layer, a first upright cotton layer and a second upright cotton layer, wherein the silica-gel layer is located at the middle, and the first upright cotton layer and the second upright cotton layer are located at the two sides of the silica-gel layer; the silica-gellayer includes a gel layer and a macromolecular thin film, wherein the gel layer is located inside the silica-gel layer, and the macromolecular thin film is located outside the silica-gel layer. According to the light artificial breast, a method of combining medical-grade silica gel with healthy, environment-friendly and low-specific-gravity upright cotton is adopted to achieve the purpose of reducing the specific gravity of an artificial breast prosthesis, and the artificial breast prosthesis has the advantages that specific gravity is low, breathability is good, and epidermis damage caused by making contact with sharp objects can be avoided; the side edge of the silica-gel layer is provided with protrusions, a guide gap is formed between every two adjacent protrusions, and therefore gasof the upright cotton with good breathability can be discharged to the outside through the guide gaps of a TPU bag, so that the light artificial breast has a good breathing function; the medical-gradesilica gel is selected, the needle penetration degree of the medical-grade silica gel is greater than that of conventional artificial breast silica gel, therefore, poor hand feeling caused by the softness of the upright cotton is offset, the feeling of the artificial breast prosthesis is close to the reality sense of the human normal breast, and the light artificial breast is comfortable to wear.

Description

technical field [0001] The invention relates to the technical field of prosthetic milk production, which is applied in the medical industry, such as external repair of human body, and in particular relates to a lightweight prosthetic milk and a manufacturing method thereof. Background technique [0002] Many breast cancer patients need to wear breast prostheses in order to maintain a normal body shape in daily life after mastectomy. Most of the prosthetic breasts currently on the market are prosthetic breasts made of silicone material combined with TPU (thermoplastic polyurethane elastomer rubber) film. This type of silicone breast prosthesis has poor air permeability; conventional silicone prosthetic breasts have a large proportion and a strong sense of weight when worn; ordinary silicone prosthetic breasts have a serious yellowing and aging of the TPU film after being used for a long time, and a little carelessness during use will cause TPU bag body Rupture and other phen...

AI Technical Summary

Problems solved by technology

This type of silicone breast prosthesis has poor air permeability; conventional silicone prosthetic breasts have a large proportion and a strong sense of weight when worn; ordinary silicone prosthetic breasts have a serious yellowing and aging of the TPU film after being used for a long time, and a little carelessness during use will cause TPU bag body Rupture and other phenomena; if the TPU film on the epidermis of ordinary silicone breast implants encounters (sharp objects, nails when wearing, etc.), it will cause the TPU film to rupture

Although the lightweight silicone prosthesis on the market is not as bulky as ordinary silicone prosthetics, the cost will be much higher than that of ordinary silicone prostheses, thus increasing the patient's expenditure cost

[0003] In addition, although some lightweight prosthetic breasts sold are cheap, they have many disadvantages, such as the prosthetic breasts filled with cotton in cloth bags, sponge molded and so on.

The first type of prosthesis satisfies the condition of lightness and breathability, but its shape is very casual, which is insufficient for the patient to wear; the second type of prosthesis is perfect in shape, but the sponge contains harmful ingredients, especially during the postoperative recovery period Not conducive to the rehabilitation of traumatic sites
