The invention provides a method for preparing a wound dressing, comprising activating a textile carrier by immersing the carrier in a solution containing functional groups to affect the oxidation thereof and pressing the activated textile to uniformly spread the functional groups into the volume of the carrier and on the surface thereof to form between about 0.026 and 0.06 mg-equiv. of aldehyde groups per gram of carrier, impregnating the active carrier in a solution of at least one bioactive enzyme and drying the same, whereby there is produced a wound dressing in which a majority of the enzyme is bound by sorption and from which the bioactive enzyme is releasable in effective amounts for a period of at least 3 days upon the dressing being brought into contact with a moist surface.
本发明提供了一种制备伤口敷料的方法,包括将纺织品载体浸泡在含有官能团的溶液中以影响其氧化,并压制活化的纺织品,使官能团均匀地扩散到载体的体积中和表面上,形成每克载体约0.026至0.06毫克当量的醛基,将活性载体浸渍在至少一种
生物活性酶的溶液中并干燥,由此制备出一种伤口敷料,其中大部分酶被敷在敷料上。将活性载体浸渍在至少一种
生物活性酶的溶液中,然后将其干燥,这样就制成了一种伤口敷料,其中大部分酶通过吸附作用结合在一起,当敷料与
潮湿的表面接触时,
生物活性酶可在至少 3 天的有效时间内从敷料中释放出来。
