Использование: получение материалов медицинского назначения, в частности перевязочных материалов, и фильтрующих материалов для фильтрования жидкостей и газов. Сущность изобретения: промытое измельченное коллагенсодержащее сырье животного происхождения подвергают щелочно-солевой обработке водным раствором, содержащим 5 - 9 мас.% NaOH и 9-11 мас.% Na2SO4 при жидкостном модуле обработки, равном 2 - 5, в течение 24 - 48 ч, после промывки водой коллагенсодержащее сырье дополнительно подвергают выдержке в 0,5 - 1,5М водном растворе кислоты при жидкостном модуле обработки, равном 1,5 - 3 с последующей промывкой водой и разволокнением коллагенсодержащего сырья в водной среде. Затем получают гомогенную пасту коллагена с pH 3 - 5,5 при обработке волокнистой массы водным 0,5 - 3%-ным раствором щелочи при массовом соотношении волокнистой массы к водному 0,5 - 3%-ному раствору щелочи, равном 1: 0,5 - 1: 2,5, с последующим доведением pH до 3 - 5,5 добавлением кислоты, вводят физиологически приемлемый сшивающий агент и, при необходимости, модифицирующую добавку, криоструктурируют коллагенсодержащую пасту в виде слоя при (2) - (-40)oC, размораживают, высушивают и получают листовой криоструктурируемый губчатый материал.Usage: obtaining medical supplies, in particular dressings, and filter materials for filtering liquids and gases. The essence of the invention: washed crushed collagen-containing raw materials of animal origin are subjected to alkaline-salt treatment with an aqueous solution containing 5 to 9 wt.% NaOH and 9-11 wt.% Na 2 SO 4 with a liquid processing module equal to 2 to 5 for 24 - 48 hours, after washing with water, the collagen-containing raw materials are additionally subjected to exposure in a 0.5-1.5 M aqueous acid solution with a liquid processing module of 1.5-3, followed by washing with water and razolokiem collagen-containing raw materials in an aqueous medium. Then get a homogeneous collagen paste with a pH of 3 - 5.5 by treating the pulp with an aqueous 0.5 - 3% alkali solution at a mass ratio of fibrous mass to aqueous 0.5 - 3% alkali solution equal to 1: 0, 5-1: 2.5, followed by adjusting the pH to 3-5.5 with the addition of acid, a physiologically acceptable crosslinking agent is introduced and, if necessary, a modifying additive, the collagen-containing paste is cryostructured as a layer at (2) - (-40) o C, thawed, dried and get a sheet of cryostructured sponge material.
