Improvements in the method of manufacture of antiseptic cotton or dressings

摘要

Antiseptic cotton or surgical dressings are impregnated by immersion in or spraying with chloramine T in solution in an alkaline medium Ammonia or sodium carbonate may be added to a solution of chloramine T in water, or the powdered antiseptic and sodium carbonate may be mixed and then dissolved. The quantity of sodium carbonate is constant at, for example, 2,5 grams per 1000 grams of water, suitable quantities of chloramine T being 25, 17,5, or 10 grams, according to the intended use. After impregnation, the dressings may first be treated in a centrifugal drier and are then airdried at 40-50 DEG C. In use, the dressing may be applied dry and then moistened.
