2 . The computer-readable medium of claim 1 , wherein:
the diverter valve is configured to allow fluid flow from the outlet of the negative-pressure source to the dressing when the diverter valve is in the second position.
3 . The computer-readable medium of claim 1 , wherein:
the diverter valve is configured to prevent fluid flow from the outlet of the negative-pressure source to atmosphere when the diverter valve is in the second position.
4 . The computer-readable medium of claim 1 , wherein the executable code comprises:
cycling the position of the diverter valve between the first position and the second position.
5 . The computer-readable medium of claim 1 , wherein the executable code comprises:
manipulating the position of the diverter valve to hold the position of the diverter valve in an intermediate position;
wherein the diverter valve is configured to allow a low flow of fluid between the outlet of the negative-pressure source and the dressing when the diverter valve is in the intermediate position.
6 . The computer-readable medium of claim 1 , wherein:
the negative-pressure source further comprises an inlet;
the inlet of the negative-pressure source is configured for fluid communication with the dressing via a first conduit; and
the outlet of the negative-pressure source is configured for fluid communication with the dressing via a second conduit.
7 . The computer-readable medium of claim 6 , wherein:
a first pressure sensor is fluidly coupled to the first conduit.
8 . The computer-readable medium of claim 6 , wherein:
a second pressure sensor is fluidly coupled to the second conduit.
9 . The computer-readable medium of claim 7 , wherein the executable code comprises:
manipulating the position of the diverter valve from the first position to the second position when a pressure at the first pressure sensor reaches a predetermined value.
10 . The computer-readable medium of claim 8 , wherein the executable code comprises:
manipulating the position of the diverter valve from the first position to the second position when a pressure at the second pressure sensor reaches a predetermined value.
11 . A method of controlling a negative-pressure wound therapy system with a computer, comprising:
manipulating, at a computer, a position of a diverter valve between a first position and a second position;
wherein:
the diverter valve is coupled between an outlet of a negative-pressure source and a dressing,
the diverter valve is configured to allow fluid flow from the outlet of the negative-pressure source to atmosphere when the diverter valve is in the first position, and
the diverter valve is configured to prevent fluid flow from the outlet of the negative-pressure source to the dressing when the diverter valve is in the first position.
12 . The method of claim 11 , wherein:
the diverter valve is configured to allow fluid flow from the outlet of the negative-pressure source to the dressing when the diverter valve is in the second position.
13 . The method of claim 11 , wherein:
the diverter valve is configured to prevent fluid flow from the outlet of the negative-pressure source to atmosphere when the diverter valve is in the second position.
14 . The method of claim 11 , further comprising:
cycling, at the computer, the position of the diverter valve between the first position and the second position.
15 . The method of claim 11 , further comprising:
manipulating, at the computer, the position of the diverter valve to hold the position of the diverter valve in an intermediate position;
wherein the diverter valve is configured to allow a low flow of fluid between the outlet of the negative-pressure source and the dressing when the diverter valve is in the intermediate position.
16 . The method of claim 11 , wherein:
the negative-pressure source further comprises an inlet;
the inlet of the negative-pressure source is configured for fluid communication with the dressing via a first conduit; and
the outlet of the negative-pressure source is configured for fluid communication with the dressing via a second conduit.
17 . The method of claim 16 , wherein:
a first pressure sensor is fluidly coupled to the first conduit.
18 . The method of claim 16 , wherein:
a second pressure sensor is fluidly coupled to the second conduit.
19 . The method of claim 17 , further comprising:
manipulating, at the computer, the position of the diverter valve from the first position to the second position when a pressure at the first pressure sensor reaches a predetermined value.
20 . The method of claim 18 , further comprising:
manipulating, at the computer, the position of the diverter valve from the first position to the second position when a pressure at the second pressure sensor reaches a predetermined value.
