Abstract

A multi-layered wound dressing includes a moisture-retaining portion for enhancing the healing of a wound. The wound dressing includes an intermediate layer that has both water soluble and water insoluble fibers. An apparatus that includes a cutting tool and a reservoir of liquid to pre-moisten a portion of the dressing may be used to manufacture the dressings.

Claims

1. An apparatus for fabricating a custom wound dressing corresponding to an identified wound, the apparatus comprising:

a case providing a sterile interior environment;

a mount for securing a strip of wound dressing material within the case, wherein the strip of the wound dressing material is fabricated outside the apparatus and includes a layer configured to engage the identified wound;

at least a first dispenser within the case, the first dispenser configured to selectively dispense a first dispensable liquid to a selected portion of the wound dressing material based on a configuration of the identified wound;

a cutting tool secured to the mount for cutting the wound dressing material into a shape based on the configuration of the identified wound; and

a relative movement mechanism disposed within the case and configured to cause relative movement between the wound dressing material and the first dispenser or the cutting tool.

2. The apparatus of claim 1, further comprising a container disposed external to the case, the container including a controller for controlling the relative movement mechanism.

3. The apparatus of claim 2, wherein the container includes user operable control buttons.

4. The apparatus of claim 1, wherein the mount comprises a spindle for holding a first roll of the strip of the wound dressing material for fabricating the wound dressing.

5. The apparatus of claim 4, further comprising a spindle for holding a second roll of a strip of the wound dressing material remaining after the customized wound dressing is fabricated.

6. The apparatus of claim 2, wherein the case is detachable from the container.

7. The apparatus of claim 1, wherein the first dispensable liquid is a member of the group consisting of a moisturizing solution, a water repellant, and an adhesive.

8. The apparatus of claim 7, further comprising a second dispenser configured to dispense a second dispensable liquid to a selected portion of the wound dressing material based on the identified wound.

9. The apparatus of claim 8 further comprising a third dispenser configured to dispense a third dispensable liquid to a selected portion of the wound dressing material based on the identified wound.

10. The apparatus of claim 2, wherein the container includes a hinged lid holding an ultraviolet germicidal lamp and the case includes a window through which the lamp can transmit ultraviolet light into the interior of the case.

11. The apparatus of claim 1, wherein the at least first dispenser includes a capillary tube having a first end coupled to a source of said first dispensable liquid at one end and a nozzle for delivering the first dispensable liquid to the wound dressing material at the other end.

12. The apparatus of claim 2, wherein the container comprises a pumping actuator for actuating a pumping of the first dispensable liquid.

13. The apparatus of claim 2, further comprising a motor operably coupled to one of a cutting tool mechanism, a wound dressing material dispenser mechanism, or a packaging mechanism for packaging the wound dressing material.

14. The apparatus of claim 2, wherein the container includes a gas pump operably coupled to the case for pumping a gas into the case.

15. The apparatus of claim 2, wherein the container includes a motor for powering said relative movement between the wound dressing material and the first dispenser.

16. A method of fabricating a wound dressing customized for a wound, comprising:

placing a strip of wound dressing material on a stage in an apparatus, the wound dressing material is fabricated outside the apparatus and includes a layer configured to engage the wound;

causing relative movement between a first dispenser and the wound dressing material;

injecting a first liquid onto a selected portion of the wound dressing material on the stage based on a configuration of the wound; and

cutting the wound dressing material into a shape by causing relative movement between a cutting tool and the wound dressing material.

17. The method of claim 16, wherein the shape is circular.

18. The method of claim 16, further comprising mounting a roll of wound dressing material onto a spindle for fabricating the wound dressing.

19. The method of claim 16, wherein the first liquid is a member of the group consisting of a moisturizing solution, a water repellant, and an adhesive.

20. The method of claim 16, further comprising injecting a second liquid onto a selected portion of the wound dressing material based on the configuration of the wound.
