Abstract

The present invention relates to a swab for treating wounds. The swab comprises a stick to one end of which is attached a wound treating element. The wound treating element has a wound cleansing element and a hemostat-containing element. A reservoir is provided for retaining a cleansing or other solution in fluid communication with the wound cleaning element.

Claims

1. A hemostatic wound cleansing swab comprising a stick and a wound treating element, said stick comprising a proximal portion, a proximal end, a distal portion, a distal end and a reservoir for containing a liquid, said wound treating element being secured to said distal portion and comprising a cleansing element for cleansing a wound and a hemostatic element for effecting hemostasis of a wound, said reservoir being in fluid communication with said cleansing element, wherein said hemostatic element is discrete from said cleansing element.

2. The swab of claim 1 wherein said stick is hollow and said reservoir is formed by a liquid-tight seal located substantially at the proximal end of said stick and a liquid-tight, frangible seal located in the distal portion of said stick.

3. The swab of claim 2 wherein said frangible seal is located substantially at the distal end of said stick.

4. The swab of claim 1 wherein said reservoir contains a liquid selected from the group consisting of wound cleansing solutions, antiseptic solutions, anesthetic solutions, antibiotic solutions, solutions of anti-inflammatory agents, and mixtures thereof.

5. The swab of claim 4 wherein said liquid is a wound cleansing solution.

6. The swab of claim 1 wherein said hemostatic element comprises a substrate material and a hemostatic agent.

7. The swab of claim 6 wherein said substrate material is selected from the group consisting of woven fabrics, nonwoven fabrics, gauze, foams and sponges.

8. The swab of claim 7 wherein said substrate material is a foam.

9. The swab of claim 1 wherein said hemostatic element comprises a hemostatic material selected from the group consisting of alginate salts, collagen, fibrin, thrombin, potato starch, bismuth subgallate, sodium hypochloride, oxidized celluloses and chitosan.

10. The swab of claim 9 wherein said hemostatic material is an alginate salt.

11. The swab of claim 9 wherein said hemostatic material is oxidized cellulose fiber.

12. The swab of claim 9 wherein a liquid impermeable film is placed between said cleansing element and said hemostatic element.

13. The swab of claim 1 wherein said reservoir contains a liquid for application to a wound.

15. The swab of claim 1 further comprising a liquid impermeable film disposed between said cleansing element and said hemostatic element.

14. A swab for use in treating a wound, said swab comprising:

a stick having a proximal portion, a proximal end, a distal portion and a distal end;

a reservoir for containing a liquid;

a hemostatic element for effecting hemostasis of a wound;

an element for applying said liquid to a wound being secured to one of said proximal and distal portions, said element for applying said liquid being discreet from said hemostatic element;

said hemostatic element being secured to the other of said proximal and distal portions;

said reservoir being in fluid communication with said element for applying said liquid to said wound.
