20090306630 | REDUCED-PRESSURE, LIQUID-COLLECTION CANISTER WITH MULTI-ORIENTATION FILTER - A reduced pressure treatment system includes a liquid-collection canister for collecting liquid from a tissue site to which reduced pressure treatment is applied. The canister includes a first space configured to collect the liquid from the tissue site and a filter having a frame and a non-planar filter element. The filter defines a second space within the canister separated from the first space by the filter element. The filter element substantially prevents liquid from passing from the first space into the second space. The filter element substantially allows gaseous communication between the first space and the second space when the second space is exposed to a reduced pressure. | 12-10-2009 |
20100042059 | REDUCED-PRESSURE TREATMENT SYSTEMS WITH RESERVOIR CONTROL - A reduced-pressure system for delivering reduced pressure for medical purposes to a desired site and to receive fluids in one instance includes a reservoir having an interior space operable to contain the fluids. A reduced-pressure delivery conduit is placed in fluid communication with the interior space for delivering the reduced pressure to the desired site. A source conduit and a pressure sensor conduit are placed in fluid communication with the interior space. A pressure sensor is placed in fluid communication with the pressure sensor conduit. A reduced-pressure source is placed in fluid communication with the source conduit. A reduced-pressure control unit is associated with the pressure sensor and the reduced-pressure source and is operable to receive pressure data from the pressure sensor and supply data from the reduced-pressure source and to determine when a reservoir-full/blockage condition exists. Other systems and methods are presented. | 02-18-2010 |

20140276492 | SYSTEM AND METHOD FOR MULTIPLE DIRECTION FLEXIBLE INLINE CANISTER - A system and apparatus for treating a tissue site with reduced pressure and collecting fluids from the tissue site is disclosed. The system may include a reduced-pressure source, a pouch in fluid communication with the reduced pressure source, and a dressing in fluid communication with the pouch. The pouch may include a first wall, a second wall having a periphery coupled to the first wall to form an interior, and a third wall extending through the interior to form a first chamber in fluid communication with the dressing and a second chamber in fluid communication with the reduced pressure source. A plurality of filters are positioned in the third wall. The filters permit fluid communication between the first chamber and the second chamber. | 09-18-2014 |
20150073361 | NEGATIVE PRESSURE THERAPY WITH DYNAMIC PROFILE CAPABILITY - An apparatus and system for fluidly connecting a reduced-pressure source to a dressing and a method for manufacturing and using the same include a base having an aperture and a wall having a peripheral portion coupled to the base. The wall may form a cavity in fluid communication with the aperture. The apparatus also may include a conduit port fluidly coupled to the cavity and adapted to receive a conduit. The base may be adapted to couple to the dressing, and the wall may be adapted to collapse from a first position to a second position in response to a supply of reduced pressure from the reduced-pressure source. | 03-12-2015 |
20150094673 | DISPOSABLE REDUCED-PRESSURE THERAPY SYSTEM WITH ELECTRONIC FEEDBACK - Systems, methods, and apparatuses for providing feedback for reduced-pressure therapy are described. A regulator can include a supply chamber fluidly coupled to a dressing, a control chamber fluidly coupled to the dressing, a charging chamber fluidly coupled to the supply chamber through a port, and a regulator valve operable to control fluid communication through the port based on a pressure differential between the control chamber and a target pressure. The feedback system can include a printed circuit board, a pressure sensor and a signal interface communicatively coupled to the printed circuit board. The pressure sensor can be fluidly coupled to the control chamber to determine the pressure in the control chamber. The signal interface can indicate a state of the reduced-pressure therapy. A potential source can be communicatively coupled to the printed circuit board, the pressure sensor, and the indicator. | 04-02-2015 |
20150094674 | DISPOSABLE REDUCED-PRESSURE THERAPY SYSTEM WITH MECHANICAL FEEDBACK - Systems, methods, and apparatuses for providing feedback for reduced-pressure treatment of a tissue site are described. A regulator may include a supply chamber fluidly coupled to the dressing, a control chamber fluidly coupled to the dressing, a charging chamber fluidly coupled to the supply chamber through a port, and a regulator valve operable to control fluid communication through the port based on a pressure differential between the control chamber and a therapy pressure. The feedback system may include one or more mechanical feedback interfaces fluidly coupled to the regulator to provide a signal of at least one of an application of reduced-pressure therapy, a leak condition, a blockage condition, and a canister full condition. | 04-02-2015 |
20150224239 | SYSTEMS AND METHODS FOR DELIVERING FLUID TO A WOUND THERAPY DRESSING - Provided are systems and methods for delivery of fluid to a wound therapy dressing. In exemplary embodiments, a pressure source provides negative pressure to a wound dressing and a biasing mechanism provides positive pressure to a fluid reservoir. | 08-13-2015 |
