Abstract
Methods and apparatuses are disclosed for applying negative pressure to a wound site. In some embodiments, the apparatus comprises a source of negative pressure, a processing element, and a memory comprising instructions configured to, when executed on the processing element, cause the apparatus to attempt to generate, via the source of negative pressure, a desired negative pressure at the wound site. If the desired negative pressure has not been generated after a first predetermined period of time, the instructions cause the apparatus to: deactivate the source of negative pressure for a second predetermined period of time, and subsequently attempt to generate the desired negative pressure at the wound site.
Claims20
A negative pressure wound therapy device comprising:
- a negative pressure source configured to provide negative pressure via a fluid flow path to a wound covered by a wound dressing;
- at least one visual indicator;
- a controller;
- and
- a memory storing instructions that, when executed by the controller, cause the controller to:
- activate the negative pressure source to attempt to establish a desired level of negative pressure in the fluid flow path;
- provide a first indication using the at least one visual indicator to indicate a leak has been detected in the fluid flow path;
- determine that the leak has not been remedied;
- responsive to determining that the leak has not been remedied, deactivate the negative pressure source for a duration of time;
- and
- responsive to expiration of the duration of time, activate the negative pressure source to attempt to establish the desired level of negative pressure in the fluid flow path.
A method of operating a negative pressure wound therapy device comprising a controller, a negative pressure source, and at least one visual indicator, the method comprising:
- activating the negative pressure source to attempt to establish a desired level of negative pressure in a fluid flow path connecting the negative pressure source to a wound covered by a wound dressing;
- providing a first indication using the at least one visual indicator to indicate a leak has been detected in the fluid flow path;
- determining that the leak has not been remedied;
- in response to determining that the leak has not been remedied, deactivating the negative pressure source for a duration of time;
- and
- responsive to expiration of the duration of time, activating the negative pressure source to attempt to establish the desired level of negative pressure in the fluid flow path,
- wherein the method is performed by the controller.
