Abstract

An apparatus and method of using same for preventing pressure ulcers is provided. More specifically, the present apparatus and method may be used in individuals having compromised mobility and/or lack of sensation to prevent pressure ulcers by electrically stimulating pressure-loaded or compressed muscles.

Claims (29)

1. A garment for preventing pressure ulcers in a loaded muscle(s), the garment comprising:

a stretchy, form-fitting main body portion,

at least one non-stretchy, opening portion comprising a layer of material forming holes therein or mesh material joined and positioned within the main body portion at or near the loaded muscles,

at least one electrode, removably received and secured by the opening portion on an external side of the opening portion, and operably linked to a stimulator for delivering an electrical stimulus for stimulating the loaded muscles, to effect contraction thereof, and to redistribute pressure of the loaded muscles and increase oxygenation.

2. The garment of claim 1 , wherein the at least one opening portion is positioned between the at least one electrode and the loaded muscle.

3. The garment of claim 1 , wherein the at least one electrode stimulates the loaded muscle through the holes in the at least one opening portion(s).

4. The garment of claim 1 , wherein the at least one electrode adheres to the at least one opening portion.

5. The garment of claim 1 , wherein the garment minimizes adhesion of the at least one electrode with the loaded muscles, while retaining electrical conductivity with the loaded muscles.

6. The garment of claim 1 , wherein the garment further comprises at one least one loose-fitting back panel portion for covering the at least one opening portion.

7. The garment of claim 6 , wherein the back panel portion moves independently of the main body portion, the at least one opening portion or the at least one electrode.

8. The garment of claim 1 , wherein the main body portion, the at least one opening portion or both comprise non-conductive material.

9. The garment of claim 1 , wherein the main body portion is formed to cover a person's upper body, lower body or both.

10. An apparatus for preventing pressure ulcers in a loaded muscle(s) of an individual having compromised mobility, the apparatus comprising:

a stretchy, form-fitting main body portion,

at least one non-stretchy, opening portion comprising a layer of material forming holes therein or mesh material joined and positioned within the main body portion at or near the loaded muscle(s),

at least one electrode, removably positioned within the opening portion on an external side of the opening portion, and operably linked to a stimulator for delivering an electrical stimulus for stimulating the loaded muscle(s), to effect contraction thereof, to redistribute pressure of the loaded muscle and increase oxygenation.

11. The apparatus of claim 10 , wherein the at least one opening portion is positioned between the at least one electrode and the loaded muscle.

12. The apparatus of claim 10 , wherein the at least one opening portion is formed from permeable material.

13. The apparatus of claim 10 , wherein the at least one electrode stimulates the loaded muscle through the at least one opening portion.

14. The apparatus of claim 13 , wherein the garment reduces adhesion of the at least one electrode with the loaded muscles.

15. The apparatus of claim 10 , wherein the apparatus may be selected from the group comprising a garment covering a person's upper body, a garment covering a person's lower body, a garment covering a person's upper and lower body, a sheet or a mattress-pad cover.

16. The apparatus in claim 10 , wherein the individual is incontinent and the apparatus is in the form of an incontinent product.

17. A method of stimulating loaded muscles in a person having compromised mobility, the method comprising:

a. providing an apparatus capable of stimulating at least a portion of the loaded muscle, wherein the apparatus comprises:

i. a stretchy, form-fitting main body portion,

ii. at least one non-stretchy, opening portion comprising a layer of material forming holes therein or mesh material joined and positioned within the main body portion at or near the loaded muscle,

iii. at least one electrode, removably received and secured by the opening portion on an external side of the opening portion, and operably linked to a stimulator for delivering an electrical stimulus for stimulating the loaded muscles,

b. stimulating the loaded muscles, through the at least one opening portion, to effect contraction of the loaded muscles, wherein contraction redistributes pressure and increases oxygenation in the loaded muscle.

18. The method of claim 17 , wherein the apparatus comprises a sheet or mattress-pad cover, or a garment covering the person's upper body, lower body or both.
