Abstract

A method and device for providing intermittent negative pressure wound healing which includes equipped to (a) apply a negative pressure compressible therapeutic dressing about a wound; (b) compress the therapeutic dressing using negative pressure to subject the wound and the therapeutic dressing to a first predetermined pressure which is low enough to provide therapy to the wound and high enough to maintain a seal between the dressing and the wound; and (c) decompress the therapeutic dressing to a second sub-atmospheric pressure above the first predetermined pressure sufficient to maintain the dressing in a generally sealed contact with the wound while relaxing compression about the wound.

Claims

1. A method for providing intermittent negative pressure wound healing which includes the steps of:

(a) applying a negative pressure compressible therapeutic dressing about a wound;

(b) compressing the therapeutic dressing using negative pressure to subject the wound and the therapeutic dressing to a first predetermined pressure which is low enough to provide therapy to the wound and high enough to maintain a seal between the dressing and the wound; and

(c) decompressing the therapeutic dressing to a second sub-atmospheric pressure above the first predetermined pressure sufficient to maintain the dressing in a generally sealed contact with the wound while relaxing compression about the wound.

2. The method of claim 1, wherein the step (b) is further characterized to be compressing to a sub-atmospheric pressure between about a range of −

50 mmHg to −

500 mmHg.

3. The method of claim 1, wherein the step (c) is further characterized to be decompressing to −

10 mmHg and −

40 mmHg.

4. The method of claim 1, wherein the therapeutic dressing includes a foam member and a semipermeable drape.

5. The method of claim 1, wherein the step (b) is between about −

75 mmHg and −

200 mmHg.

6. The method of claim 1, wherein the step (b) is further characterized to employ a negative pressure vacuum device.

7. The method of claim 1, which includes the step (d) of repeating steps (b) and (c) for a predetermined period.

8. The method of claim 7, wherein step (b) is performed for a first predetermined time and step (c) is performed for a second predetermined time.

9. The method of claim 8, wherein said first predetermined time and the second time predetermined time are the same.

10. The method of claim 8, wherein said first predetermined time and the second time predetermined time are the different.

11. The method of claim 1, which includes the step (d) of repeating step (b) and decompressing the therapeutic dressing to a third sub-atmospheric pressure above the first predetermined pressure sufficient to maintain the dressing in a generally sealed contact with the wound wherein the third sub-atmospheric pressure is not equal to the second sub-atmospheric pressure.

12. The method of claim 11, wherein step (b) is performed for a first predetermined time and step (c) is performed for a second predetermined time different than said first predetermined time.

13. The method of claim 12, wherein said first predetermined time and the second time predetermined time are the same.

14. The method of claim 12, wherein said first predetermined time and the second time predetermined time are the different.

15. A therapeutic device for providing intermittent negative pressure wound healing includes fluid moving means for one of raising, compressing, or transferring fluid, a compressible therapeutic member operably connected to the fluid moving means and actuated thereby, the compressible therapeutic member operably disposably used on a patient in a manner to deliver therapy to the patient as function of actuation of the fluid moving means;

and control means operably associated with the fluid moving means for controlling application of a negative pressure to the compressible therapeutic member about a wound in a manner to compress the compressible therapeutic member using negative pressure to subject the wound and the compressible therapeutic member to a first predetermined pressure which is low enough to provide therapy to the wound and high enough to maintain a seal between the compressible therapeutic member and the wound and decompressing the compressible therapeutic member to a second sub-atmospheric pressure above the first predetermined pressure sufficient to maintain the compressible therapeutic member in generally sealed contact with the wound while relaxing compression about the wound, and a power source to supply power to the fluid moving means and said control means.

16. The therapeutic device of claim 15, wherein said control means is operably associated with said fluid moving means for controlling operation thereof in a manner to restrict use of said fluid moving means by said patient in accordance with a predetermined treatment plan or duration and render inoperable said pump.

17. The therapeutic device of claim 15, which includes a rechargeable power source to supply power to said fluid moving means.

18. The therapeutic device of claim 17, wherein said rechargeable power source is removable.

19. The therapeutic device of claim 17, wherein said rechargeable power source is a battery.

20. The therapeutic device of claim 19, wherein said rechargeable power source is removable.

21. The therapeutic device of claim 15, wherein said therapeutic member includes a compressible dressing.

22. The therapeutic device of claim 15, wherein said control means includes a timer for restricting said use as a function of a predetermined time.

23. The therapeutic device of claim 15, which further includes an identification member such that said control means restricts use as a function of a said identification member.

24. The therapeutic device of claim 15, wherein said control means includes means for remote control thereof for restricting said use.

25. The therapeutic device of claim 15, which further includes a container removably operably interconnected to said fluid moving means and to said therapeutic member to receive waste fluid therein as a result of actuation of said fluid moving means.

26. The therapeutic device of claim 15, which further includes a housing operably containing said control means and said fluid moving means.

27. The therapeutic device of claim 15, which further includes a rechargeable power source operably connected to said housing to supply power to said fluid moving means and said control means.

28. The therapeutic device of claim 27, wherein said rechargeable power source is removably connected to said housing.

29. The therapeutic device of claim 26, wherein said housing is further characterized to contain said control means and said fluid moving means in a waterproof manner.

30. The therapeutic device of claim 15, which further includes a pressure sensor operably connected to said control means and said therapeutic member such that said control means controls said fluid moving means as a function of said sensed pressure.

31. The therapeutic device of claim 26, wherein said housing includes a control display panel operably thereon and connected to said control means.
