The collection canister has ports to introduce a vacuum from the vacuum source into the collection canister. A ball float is provided to substantially close the suction port in response to one of collection of a predetermined volume of exudate in the collection canister, tilting of the collection canister beyond a predetermined angle of orientation or inversion of the collection canister. | 01-14-2010 |
| 20080300578 | Sub-atmospheric Wound-Care System - Methods and systems are provided for a sub-atmospheric wound-care (SAWS) system for treating an open wound. The SAWS system includes a regulated vacuum source for developing a negative pressure, a flow rate meter configured to measure a flow rate of liquid removed from the wound, a primary pressure regulating sensor located proximate the wound for directly measuring the negative pressure at the wound, a backup pressure regulating sensor located vacuum tube, a porous dressing suitable to be sealed airtight which is positioned within a wound interface chamber, a collection canister configured to collect said liquid removed from the wound, and an adapter configured to use wall suction a primary regulated vacuum source. | 12-04-2008 |
| 20100168719 | PROCESSING SYSTEM AND COLLECTING DEVICE THEREOF - A processing system is utilized to process and absorb a fluid discharging from a source. The processing system includes an absorbing device to absorb the fluid, a driving device and a collecting device. The driving device connected to the absorbing device drives the fluid collected by the absorbing device to move, and the collecting device connected to the driving device is utilized to collect the fluid driven by the driving device. The collecting device includes a base and an absorbing element. The based includes a first layer, a second layer and a guiding area formed by the first and second layers. The guiding area includes two channels connected to each other. The absorbing element enclosed by the first and second layers of the base is disposed next to the guiding area, so that the fluid guided by the two channels of the guiding area is absorbed by the absorbing element. | 07-01-2010 |
| 20130096536 | SYSTEM AND APPARATUS FOR TREATING A TISSUE SITE HAVING AN IN-LINE CANISTER - A canister for use in administering reduced pressure to a tissue site includes a center body, a first end cap, and a second end cap. The center body includes a first end, second end, and a number of fluidly separate body conduits. The first end cap is connected to the first end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The first end has a port for receiving a conduit in fluid communication with the tissue site. The second end cap is connected to the second end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The second end cap has a port for receiving a conduit in fluid communication with a reduced pressure source. The fluid connection between the body conduits and the return conduits creates a continuous, tortuous pathway. | 04-18-2013 |
| 20130123755 | SYSTEM AND METHOD FOR DETERMINING A FILL STATUS OF A CANISTER OF FLUID IN A REDUCED PRESSURE TREATMENT SYSTEM - A reduced pressure treatment system is provided that includes a canister that is fluidly connected to a tissue site and is configured to receive fluid drawn from the tissue site under the influence of a reduced pressure. A reduced pressure source provides the reduced pressure and is fluidly connected to the tissue site by a fluid communication path, which may include a source conduit, the canister, and a target conduit. A sensing device communicates with the source conduit and is configured to sense a pressure in the source conduit. A valve communicates with the source conduit and is configured to vent the reduced pressure. A processing unit communicates with the sensing device and the valve and is configured to open the valve for a selected amount of time, determine a decay of reduced pressure, and determine a fill status of the canister based on the decay of reduced pressure. | 05-16-2013 |
| 20080200906 | Apparatus and method for administering reduced pressure treatment to a tissue site - The illustrative embodiments described herein are directed to a system and method for administering reduced pressure at a tissue site. The apparatus includes a reduced pressure source. The reduced pressure source generates a reduced pressure. The apparatus includes a tube having a plurality of lumens. The plurality of lumens includes at least one collection lumen. The reduced pressure source applies the reduced pressure to the tissue site through the plurality of lumens such that the at least one collection lumen receives fluid from the tissue site. The at least one collection lumen stores the fluid received from the tissue site. | 08-21-2008 |
| 20080200905 | System and method for applying reduced pressure at a tissue site - The illustrative embodiments described herein are directed to a manually-actuated pump and method for applying reduced pressure at a tissue site. The manually-actuated pump includes at least one variable volume chamber that is manually compressible into a plurality of positions. The manually-actuated pump includes a fixed volume chamber in communication with the at least one variable volume chamber. The manually-actuated pump also includes a filter housing having a hydrophobic filter that prevents liquid from entering the at least one variable volume chamber. The fixed volume chamber is coupled to the at least one variable volume chamber via the filter housing. The filter housing is located in between the at least one variable volume chamber and the fixed volume chamber. The fixed volume chamber has reduced pressure that is applied to the tissue site in response to a movement of the at least one variable volume chamber from a compressed position in the plurality of positions to an uncompressed position in the plurality of positions. | 08-21-2008 |
