Method for producing a substance adapted to tampon wounds
Abstract
Abstract 229,644. Vogel, R. Feb. 19, 1924, [Convention date]. Medicaments for external application. - A dressing for wounds, which is applied in a liquid or plastic state but which stiffens or coagulates after application and is ultimately absorbed by the body, consists of blood, preferably freed from red corpuscles, to which sodium citrate or like salt has been added in such quantity as just to prevent coagulation. Immediately before use a salt such as chloride of calcium is added to induce coagulation. Disinfectants, such as chinosol or eucupin (ethyl-hydro-cuprein), may also be added. The Specification as open to inspection under Sect. 91 (3) (a) states also that pure blood plasma may be used in place of blood. This subjectmatter does not appear in the Specification as accepted.
