Device with controller and pump modules for providing negative pressure for wound therapy
A device for use with a negative pressure bandage for supply negative pressure. The device includes a pump module and a controller module. The pump module contains a power source and a pump. The pump module is removably contained in the controller module. The pump module and controller module can be connected with a connector that provides both a physical and pneumatic connection. The controller module may include one of more visual indicators for allowing the status of the device to be observed at a distance.
1. A device for use with a negative pressure wound therapy bandage, the device comprising:
a controller module including:
a housing configured to receive a pump module and configured to substantially enclose the pump module;
a circuit board having a CPU and support electronics;
a check valve; and,
a pressure sensor; and
the pump module including a pump and a power source, the pump module configured to be placed in the housing recess and to be removably enclosed by the housing,
wherein negative pressure from the pump is communicated through at least the check valve to the negative pressure wound therapy bandage.
2. A kit comprising:
a device including:
a controller module including:
a housing configured to receive a pump module and configured to substantially enclose the pump module,
a circuit board having a CPU and support electronics,
a check valve, and,
a pressure sensor; and,
the pump module including a pump and a power source, the pump module configured to be placed in the housing and to be removably enclosed by the housing;
a negative pressure wound therapy bandage,
wherein negative pressure from the pump is communicated through at least the check valve to the negative pressure wound therapy bandage.
3. The device of claim 1 wherein the pump module includes a housing and the pump and power source are contained within the housing of the pump module.
4. The device of claim 3 wherein the housing of the controller module slidably receives the housing of the pump module.
5. The device of claim 1 further comprising:
a connector for connecting the controller module to the pump module, wherein the connector provides a physical connection and a pneumatic connection.
6. The device of claim 5 wherein the connector includes a button release.
7. The device of claim 6 wherein the housing of the controller module includes an aperture and the button release is accessible through the aperture.
8. The device of claim 1 wherein the pump creates a negative pressure that is communicated to the controller module and out of the controller module though a port in the housing of the controller module.
9. The device of claim 1 wherein the controller module further includes at least one visual indicator that provides an indication of a status of the device at a distance greater than 5 feet.
10. The device of claim 9 further comprising a case removably receiving the device and having an adjustable strap capable of being mounted on a plurality of different items.
11. The device of claim 1 further comprising at least one spring in the housing of the controller module that provides a force on the pump module away from the controller module.
12. The device of claim 5 further comprising at least one spring in the housing of the controller module wherein when the connector is disengaged the at least one spring provides a force on the pump module to move the mump module away from the controller module.
13. The kit of claim 2 further comprising:
a connector for connecting the controller module to the pump module, wherein the connector provides a physical connection and a pneumatic connection.
14. The kit of claim 2 wherein the negative pressure wound therapy bandage collects and stores exudates within the bandage.
15. The kit of claim 2 further comprising tubing to connect the device to the negative pressure wound therapy bandage.
16. The device of claim 1 further comprising tubing to connect the device to the negative pressure wound therapy bandage.
17. The kit of claim 13 wherein the connector includes a button release.
18. The kit of claim 17 wherein the housing of the controller module includes an aperture and the button release is accessible through the aperture.
