Abstract
A prepackaged coagulant composition and method of preparing same has been devised for use in direct or topical application to wounds so as to cause superficial clotting in which thrombin is combined with special preservatives and a saline solution. A ready-to-use bandage is saturated with the resultant solution, sealed and stored so as not to lose its reactive properties with the fibrinogen in the blood when applied to a wound or cut.

A coagulant adaptable for use as a dressing for wounds comprising a solution of 50-2000 units of thrombin per ml of an aqueous solution containing sodium chloride in about isotonic quantities and from 10-50% by weight of a straight chain 3 to 6 carbon fully hydroxylated polyol.
A prepackaged coagulant material adaptable for use as bandages, dressings and the like for wounds comprising in combination:
- a solution of thrombin containing sodium chloride in about isotonic proportions together with from 10-50% by weight of a straight chain 3 to 6 carbon fully hydroxylated polyol, and
- an absorbent material saturated by said solution, and sealing means hermetically sealing said saturated absorbent material.
