Abstract

Embodiments of reduced pressure systems and methods for operating the systems are disclosed. In some embodiments, a system can include a source of negative pressure and a controller configured to present GUI screens for controlling and monitoring operation of the system. The controller can be configured to receive, via the GUI, an adjustment of a negative pressure therapy parameter and adjust (or cause adjustment) of the operation of the negative pressure source based on received adjustment. The controller can be further configured to record historical data parameters associated with negative pressure therapy parameters. The controller can also be configured to transmit (or cause transmission) over a communication channel at least some of recorded historical data. The system can be configured to provide external connectivity for accomplishing various activities, such as location tracking, compliance monitoring, tracking of operational data, remote selection and adjustment of therapy settings, etc.

Claims

1. A system for applying negative pressure to a wound, the system comprising:

a housing comprising a source of negative pressure and a controller, the source of negative pressure configured to be in fluidic communication with a wound dressing placed over the wound, and the controller configured to operate the source of negative pressure to aspirate fluid from the wound; and

a mounting system configured to attach the housing to a structure, the mounting system comprising;

a cradle configured to be removably attached to the housing;

a first clamp arm attached to the cradle;

a second clamp arm configured to be moved between a clamped position and an unclamped position, wherein the first and second clamp arms are configured to be substantially securely attached to the structure in the clamped position; and

a first screw engaged with a second screw, the second screw being attached to the second clamp arm,

wherein the first screw comprises a first thread configured to engage with a second thread of the second screw, the first thread being positioned on an interior of the first screw and the second thread being positioned on an exterior of the second screw,

wherein a rotation of the second screw is configured to rotate the first screw and move the second clamp arm between the clamped and unclamped positions.

2. The system according to claim 1, wherein the first and second clamp arms are configured to support a weight of the housing in the clamped position.

3. The system according to claim 1, wherein the first thread is oriented in a first direction, and the second thread is oriented in a second direction opposite from the first direction.

4. The system according to claim 1, further comprising a handle attached to the second screw, whereby a rotation of the handle causes the second clamp arm to move a distance proportional to an aggregate of a first lead of the first screw and a second lead of the second screw.

5. An attachment system for mounting an apparatus, the attachment system comprising:

a cradle configured to be removably attached to the apparatus;

a first clamp arm attached to the cradle;

a second clamp arm configured to be moved between a clamped position and an unclamped position, wherein the first and second clamp arms are configured to be substantially securely attached to a structure in the clamped position; and

a first screw engaged with a second screw, the second screw being attached to the second clamp arm,

wherein the first screw comprises a first thread configured to engage with a second thread of the second screw, the first thread being positioned on an interior of the first screw and the second thread being positioned on an exterior of the second screw,

wherein a rotation of the second screw is configured to rotate the first screw and move the second clamp arm between the clamped and unclamped positions.

6. The attachment system according to claim 5, wherein the first and second clamp arms are configured to not be substantially securely attached to the structure in the unclamped position.

7. The attachment system according to claim 5, wherein the first and second clamp arms are configured to support a weight of the apparatus in the clamped position.

8. The attachment system according to claim 5, further comprising a knob attached to the second screw, the knob configured to move the second clamp arm between the clamped and unclamped positions.

9. The attachment system according to claim 5, wherein the first and second screws are power screws.

10. The attachment system according to claim 5, wherein the first and second threads are Acme threads.

11. The attachment system according to claim 5, wherein the first screw comprises a substantially hollow interior portion, and at least a part of the second screw is configured to be positioned in the interior portion of the first screw in the clamped position.

12. The attachment system according to claim 5, wherein the first thread is oriented in a first direction, and the second thread is oriented in a second direction opposite from the first direction.

13. The attachment system according to claim 5, further comprising a handle attached to the second screw, whereby a rotation of the handle causes the second clamp arm to move a distance proportional to an aggregate of a first lead of the first screw and a second lead of the second screw.

14. The attachment system according to claim 5, wherein the second clamp arm is further configured to be moved between a fully open and a fully closed position, the first and second clamp arms being in contact in the fully closed position, and the first and second clamp arms being separated by a distance in the fully open position, whereby about four rotations of a knob attached to the second screw cause the second clamp arm to move between the fully closed and fully open positions.

15. The attachment system according to claim 5, wherein the structure comprises at least one of a pole or a bedrail.

16. The attachment system according to claim 5, wherein the apparatus comprises a pump.

17. The attachment system according to claim 5, wherein the apparatus comprises a negative pressure wound therapy (NPWT) apparatus.

18. The attachment system according to claim 17, further comprising the NPWT apparatus, wherein the NPWT apparatus comprises a negative pressure source configured to be fluidically connected to a wound dressing, the wound dressing configured to be placed over a wound and to create a substantially fluid impermeable seal over the wound.

19. The attachment system according to claim 5, wherein

the cradle comprises the first clamp arm, a housing, and a plurality of latches configured to be removably attached to the apparatus,

the first screw positioned at least partly within the housing of the cradle, and

the second screw positioned at least partly within the housing of the cradle.

20. The attachment system according to claim 5, wherein the rotation of the second screw is configured to linearly move the second clamp arm between the clamped and unclamped positions.
