Title

(ZH) 一种应用于治疗脉管异常的乙醇泡沫硬化剂及制备方法
Abstract
(EN)
An ethanol foam hardener applied to the treatment of vascular anomalies and a preparation method, comprising absolute ethanol, water, Tween 80, and a stabilizer. Further comprised is hyaluronic acid. The ethanol foam hardener comprises 32-42% absolute ethanol, 0.5-2% Tween 80, 0-25 (not comprising 0) egg yolk lecithin, 0-2% (not comprising 0) hyaluronic acid, and the remainder is water. The stabilizer is hyaluronic acid or glycerin. A Tessari method is used to prepare foam, which may significantly reduce the side effects of ethanol while not changing the original therapeutic effects of the ethanol.
(FR)
L'invention concerne un durcisseur de mousse d'éthanol appliqué au traitement d'anomalies vasculaires et un procédé de préparation, comprenant de l'éthanol absolu, de l'eau, du Tween 80 et un stabilisant. L'invention concerne en outre de l'acide hyaluronique. Le durcisseur de mousse d'éthanol comprend de 32 à 42 % d'éthanol absolu, des 0,5 à 2 % de Tween 80, des 1 à 25 lécithines de jaune d'œuf, de 1 à 2 % d'acide hyaluronique, et le reste étant de l'eau. Le stabilisant est l'acide hyaluronique ou la glycérine. Une méthode de Tessari est utilisée pour préparer la mousse, ce qui peut réduire de manière significative les effets secondaires de l'éthanol tout en ne modifiant pas ses effets thérapeutiques originaux.
