The hemostat according to the invention preferably contains additives such as foaming additives or physiologically active substances. The further subject of the invention is the method of producing the collagen hemostat by acidifying a source of native collagen, heating the collagen to a temperature of 30-50 DEG C under agitation, neutralizing the collagen by addition of an alkaline solution and expanding the collagen to obtain a liquid of low density. The collagen hemostat according to the invention can be used in various surgical interventions, in particular of laparoscopic procedures. |
