Title: The Innovative Contributions of Herbert Lettau
Introduction
Herbert Lettau is a notable inventor based in Leipzig, Germany, recognized for his significant contributions to the field of medical technology. With a total of four patents to his name, Lettau has focused on developing advanced wound care solutions that enhance patient safety and recovery.
Latest Patents
One of Lettau's latest patents is an absorbing wound dressing and method for making the same. This innovative dressing is designed to be atoxic and tissue compatible, ensuring it fits well to the shape of the wound. It is easily removable and protects against infections by absorbing not only wound exudate but also bacteria, fungi, toxins, proteins, and inflammation mediators. This makes it suitable for covering and cleaning heavily exuding, infected wounds, as well as affected areas in skin and tissue diseases. The dressing consists of potentially macroporous particulate mixtures of regenerated cellulose and a carboxylate groups containing polysaccharide derivative. The manufacturing process involves thermally coagulating, purifying, and drying viscose solutions that contain the polysaccharide derivative after deformation.
Another significant patent by Lettau is for a dressing for wounds and the method for manufacturing thereof. This absorbing dressing consists of spherical particles of regenerated cellulose, ranging in size from 0.05 to 0.5 mm, and features a macroporous structure characterized by a cyclohexane regain of the dry material of at least 0.2 ml/g. The dressing is prepared from regenerated cellulose that has been swollen with water, followed by replacement with organic solvents and subsequent drying of the product, which is then impregnated with a therapeutically active compound.
