Abstract

An apparatus including a pump and control unit to be used to provide negative pressure for a wound therapy device. The pump module includes a pump and a pressure sensor, and the control unit module is capable of determining the pump in the pump module. The apparatus has a handheld size.

Claims

1. An apparatus to be used to provide negative pressure for a wound therapy device, the apparatus comprising:

a pump module comprising;

a pump wherein the pump is selected from the group consisting of;

a continuous pump, an intermittent pump, and a hybrid pump; and

,

a pressure sensor; and

,

a control unit module in electrical communication with the pump module and capable of determining the pump in the pump module.

2. The apparatus of claim 1 further comprising a port for communicating a negative pressure.

3. The apparatus of claim 2 wherein the port further comprises a tubing and a quick release valve.

4. The apparatus of claim 1 further comprising a power source.

5. The apparatus of claim 4 wherein the power source comprises at least two AA batteries.

6. The apparatus of claim 1 further comprising a housing wherein the housing has a handheld size.

7. An apparatus to be used to provide negative pressure for a wound therapy device, the apparatus comprising:

a pump for creating a negative pressure;

a port for providing communication of the negative pressure; and

,

a power source for the pump, wherein the power source comprises three AA batteries.

8. The apparatus of claim 7, wherein the pump is selected from the group consisting of:

a continuous pump, an intermittent pump, and a hybrid pump.

9. The apparatus of claim 8 further comprising a housing wherein the housing has a handheld size.

10. The apparatus of claim 7 further comprising a tubing communicating with the port and a quick release valve disposed at an end of the tubing.

11. An apparatus to be used to provide negative pressure for a wound therapy device, the apparatus comprising:

a pump for creating a negative pressure;

a port for providing communication of the negative pressure;

a power source for the pump; and

,

a housing containing the pump, the port and the power source, wherein the housing has a handheld size.

12. The apparatus of claim 11 further comprising the pump being selected from the group consisting of:

a continuous pump, an intermittent pump, and a hybrid pump.

13. The apparatus of claim 12 further comprising a tubing communicating with the port and a quick release valve disposed at an end of the tubing.

14. The apparatus of claim 12 further comprising a control unit module in electrical communication with the pump and capable of determining the pump.

15. The apparatus of claim 11 wherein the housing has a length approximately five inches, a width approximately three inches and a thickness approximately an inch and a half.

16. The apparatus of claim 15 wherein the apparatus has an overall weight of eight ounces.

17. The apparatus of claim 11 wherein the housing has a length less than approximately nine inches, a width less than approximately seven inches and a thickness less than approximately four inches.

18. The apparatus of claim 11 further comprising an LCD display.

19. The apparatus of claim 11 further comprising a means for mounting the apparatus to a belt.

20. A method for treating a wound with negative pressure, the method comprising the steps of:

providing a wound therapy dressing;

providing an apparatus including a pump contained in a housing, wherein the housing has a handheld size; and

,

utilizing the pump to provide a negative pressure, wherein the exudates are retained within the wound therapy dressing.

21. The method of claim 20 wherein the pump is a hybrid pump and further comprising the step of:

selecting the mode of operation of the pump.

22. The method of claim 20 further comprising the step of:

mounting the apparatus to a belt.
