METHOD OF MANUFACTURING COLLAGEN SPONGE, A DEVICE FOR EXTRACTING A PART OF COLLAGEN FOAM AND EXTENDED COLLAGEN SPONGE

摘要

A method of making a collagen sponge involves adding air to the collagen gel and mixing to obtain collagen foam, which is then dried. From the dried product obtained in this way, a collagen sponge is obtained by separating parts of the sponge with a chamber diameter of more than 0.75 mm and less than 4 mm or parts with an average diagonal size of the chambers of 3 mm Collagen sponge can be used as a wound closure material, possibly coated with fibrin glue, for example a combination of fibrinogen, thrombin and aprotinin. A device is described for extracting a portion of collagen foam and converting another portion of collagen foam back to a collagen gel. An extended collagen sponge with a through hole and an elastic wall can be used to restore the system of the gastrointestinal tract and trachea in mammals.
