Abstract

A hemostatic article, e.g., a sponge is pretreated with predetermined quantities of selected hemostatic agents to assist hemostasis in surgical or traumatic wounds. The hemostatic article is provided with a visible marking/indication of the strength of the hemostatic agent. The visible indication may be color coding, or, the marking could take the form 20%, 40%, 60% and, 80%. The hemostatic agent may be any substance assisting in hemostasis, may be in powder or fluid form, and may be one or more of Thrombin, Gelform, Fibrinogen, or other hemostatic substances. The hemostatic article could include at least one radio-opaque element which may take the form of a thread or a strip. Alternatively, a radio chip embedded in the hemostatic article may be used. The visible markings per se could be made radio-opaque, thereby obviating a separate radio-opaque element. The pretreated marked hemostatic articles are sterilized for medical use in any known manner.

Claims

1. A hemostatic article which is pretreated with a predetermined quantity of one or more hemostatic agents, the hemostatic article including a visible indication thereon, of said predetermined quantity of said one or more hemostatic agents.

2. The hemostatic article as in claim 1, wherein said hemostatic agents are in powder form, and wherein said visible indication comprises percentage quantity markings such as 20%, 40%, 60%, 80% on each said hemostatic article.

3. The hemostatic article as in claim 2, wherein said article comprises a sponge and includes at least one radio-opaque element included therein.

4. The hemostatic article as in claim 3, wherein said radio-opaque element comprises a radio-opaque thread.

5. The hemostatic article as in claim 2, wherein said article comprises a sponge, and wherein said percentage quantity markings are printed to be boldly visible on said hemostatic article, said markings being radio-opaque.

6. The hemostatic article as in claim 2, wherein said article comprises a sponge, and wherein said markings are provided on two sides of the sponge.

7. The hemostatic article as in claim 2, wherein said article comprises gauze, and said percentage quantity markings are provided on two sides of the gauze.

8. The hemostatic article as in claim 2, wherein said article comprises gauze, and said percentage quantity markings are in the form of multiple markings on each side of the gauze.

9. The hemostatic article as in claim 1, wherein said visible indication comprises color coding using different colors to represent said predetermined quantity of said one or more hemostatic agents as percentages including 20%, 40%, 60% and 80%.

10. The hemostatic article as in claim 5, wherein said percentage quantity markings are provided on two sides of the sponge.

11. A hemostatic sponge including gauze material which is pretreated with a predetermined quantity of one or more hemostatic agents, the hemostatic sponge including a visible indication of said predetermined quantity of said one or more hemostatic agents.

15. The hemostatic sponge as in claim 11, wherein said hemostatic agents include one or more of Thrombin, Gelform, fibrinogen, cellulose, Aminocaproic acid, Tranexamic acid, Aprotinin®

, Desmopressin® and
