A PROCESS OF COMPOSITION FOR MEDICAL USE

Abstract: The present patent application relates to an original composition process (a chemical formula) of a product for medical use in repair and esthetic surgery. In general, the process utilizes as a vehicle a colloid of a viscosity which is adequate to the subcutaneous tissues, and requiring the carboxy-gluconate-hydro-lactic of magnesium, according to the process described in the accompanying report.

Description: A PROCESS OF COMPOSITION FOR MEDICAL USE The present application for privilege relates to an original composition process (a chemical formula) of a product for medical use, to mend small hollow parts of the body surface, by means of an injection in the affected tissues, to be used in plastic and esthetic surgery, (especially in creases, wrinkles, lips, nose, hands and other parts) , with unique features which are capable of distinguishing it from the state of the art, and having practical and functional benefits, forming a set of conditions which make it deserving the protection saught. The acrylates were discovered in Germany in 1902 and their medical use in 1935, and for about: 12 years they been used in medical repair and esthetics. The MetaAcrylates are small spheres which need a vehicle to become injectable. So far, two vehicles have been used for that purpose: 1 - Bovine collagen, a long-chain protein, which has a high risk of allergy and can be a virus carrier, as recently accurred with bovine encephalitis. 2 - Liquid silicone, which has not yet been approved for general use, as it can cause siliconomas. In general, the process which is the object of the present application uses as a vehicle a colloid of an adequate viscosity to the subcutaneous tissues, making possible a practical and safe filling, without the limiting conditions mentioned above. In order to better illustrate this description, reference is made to the composition (hydro lactic carboxy gluconate of magnesium) (Colloidal CGLM-meta acrylate) , which illustrates the process of preparation, so that on a sterile vessel the following substances are placed in adequate proportions to attain the required viscosity: CMC, Rmguer lactate, and EDTA. From time to time the mixture is put into a shaker- mixer and heated to 50 °C for 3 hours, a procedure which must be repeated every 24 hours 4 times. After this period of homogenization, the MetaAcrylate spheres are added m a sufficient quantity to obtain the desired product. The new mixture is put into a mixer rotating in slow motion for 40 minutes every 12 hours during 3 days. At this stage of the production process calcium gluconate is added. All the contents are subjected to a vacuum and a simultaneous mechanical shaking to eliminate the excess air contained in the Rmguer water. In the final stage, the product is placed in previously sterilized bulbs and again subjected to mechanical shaking for about two hours, after which the bulbs are sealed and subjected to a new sterilization, and finally are cooled to de-condense the humidity on the walls of the bulbs.

Claims: What is claimed is: 1. Process of composition for medical use characterized by utilizing as a vehicle a colloid of a viscosity which is adequate to subcutaneous tissues, and the composition (carboxy-gluconate-hydro-lactic of magnesium) (colloidal CGLM-meta acrylate) requiring the process of preparation described in detail in the accompanying report.
