Abstract

A device and method for chronic wound treatment is disclosed. The device is in the form of a slide rule which instructs the user regarding a recommended course of treatment based on the healing phase condition and moisture condition of the wound.

Claims (143)

1. A device comprising a sliding member and a fixed member, the sliding member indicative of the moisture condition of a wound and the fixed member indicative of the healing phase condition of a wound and containing instructions as to the wound treatment regiment resulting from the alignment of the sliding member's particular wound moisture condition with the fixed member's particular wound healing phase condition.

2. The device of claim 1 , wherein the sliding member is indicative of the wound's healing phase condition and the fixed member is indicative of the wound's moisture condition.

3. A device useful for prescribing a treatment regiment for chronic wounds comprising:

(a) a base comprising first and second elongated fixed members, the members being spaced to receive a moveable slide;

(b) the moveable slide being located between the two spaced elongated fixed members;

(c) the first of the elongated fixed members separated into regions indicating the healing phase condition of the wound in terms of whether the wound is in the necrotic condition; fibrinous slough or infection condition; granulation condition; or epithelialization condition; each of these healing phase condition regions further containing indicators corresponding to the moisture condition of the wound indicating whether the moisture level of the wound is in the wet condition; moist condition, or dry condition;

(d) the moveable slide being separated into three regions corresponding to the moisture condition of the wound in terms of whether the wound is in the wet condition, moist condition, or dry condition; each of these moisture condition regions further containing wound healing phase indicators corresponding to the healing phase condition of the wound in terms of whether the wound is in the necrotic condition; fibrinous slough or infection condition, granulation condition; or epithelialization condition; and

(e) the second of the elongated fixed members comprising treatment descriptors comprising instructions for wound treatment regiments corresponding to the wound phase healing and moisture conditions which result from the alignment of the healing and moisture condition indicators of the first elongated fixed member with the healing phase and moisture condition indicators of the moveable slide.

4. The device of claim 3 , wherein the wound healing phase condition regions are of the first elongated fixed member shaded or colored to distinguish the regions from among themselves.

5. The device of claim 4 , wherein the wound moisture condition regions of the movable slide are shaded or colored to distinguish the regions from among themselves.

6. The device of claim 5 , wherein the healing phase condition regions have the following coloring scheme of black to depict the necrotic condition, yellow to depict the fibrinous slough or infection condition, red to depict the granulation condition and pink to depict the epithialization condition.

7. The device of claim 6 , wherein the wound moisture condition regions have the following coloring scheme of blue to depict a wet wound, green to depict a moist wound, and yellow to depict a dry wound.

8. The device of claim 7 , wherein the moisture condition indicators of the first elongated fixed member, the wound healing phase indicators of the moveable slide, and the indicators of the second elongated fixed member are shaded or colored.

9. The device of claim 8 , wherein the moisture condition indicators of the first elongated member, the wound healing phase indicators of the sliding member, and the indicators of the second elongated member each individually comprise two side-by-side colored bars.

10. The device of claim 9 , wherein the indicators comprise the following left to right color scheme for the indicated wound healing and moisture conditions:

11. A method for prescribing a treatment regiment for a wound comprising the steps of:

(a) assessing the wound healing phase condition;

(b) assessing the wound moisture condition; (c) providing a device comprising at least two fixed members and a sliding member, the first of the fixed members representing the wound healing condition, the sliding member representing the wound moisture condition, and the second of the fixed members comprising wound treatment instructions;

(d) aligning the moisture condition of the sliding member with the wound healing phase condition of the first fixed member corresponding to the assessed wound healing phase and moisture condition and then prescribing the wound treatment regiment indicated on the second fixed member resulting from the alignment of the sliding member and the first fixed member.
