A portable negative pressure wound therapy system includes a dressing assembly for positioning over a wound to apply a negative pressure to the wound and a canister assembly. The canister assembly includes a control unit having a vacuum source and a controller and a collection canister in communication with the dressing assembly operable to receive fluid from the wound. The collection canister has a filter assembly having a filter and a passageway between the filter and a wall of the collection canister. The collection canister also includes a canister interface having a suction port, an inlet port, and a channel. The vacuum source draws air through the suction port from the channel which draws air from the passageway connected to the channel, the air in the passageway is drawn from the collection canister through the filter, and the air in the collection canister is drawn through the inlet port.

A waste collection and disposal system for use in health care facilities is provided. The system includes a mobile waste collection unit for moving between use areas in the health care facility to collect waste material generated during medical procedures including body fluids, body tissues, saline, etc. The waste collection unit includes stacked upper and lower waste containers for receiving the waste material. During use, the upper waste container can be emptied into the lower waste container for temporary storage. In addition, different vacuum levels can be provided in the waste containers during complex procedures. Once a user desires to empty the waste collection unit, the waste collection unit is wheeled to a docking station. At the docking station, the waste material is off-loaded to a waste drain and the waste collection unit is cleaned and rinsed for further use.

A portable system for subatmospheric pressure therapy in connection with healing a surgical wound, includes a wound dressing dimensioned for positioning relative to a wound bed of a subject, a portable subatmospheric pressure mechanism dimensioned to be carried or worn by the subject and a container for collecting exudates from the wound bed removed under the subatmospheric pressure supplied by the subatmospheric pressure mechanism. The portable subatmospheric pressure mechanism includes a housing, a subatmospheric pressure source disposed within the housing and in fluid communication with the wound dressing to supply subatmospheric pressure to the wound dressing and a power source mounted to or within the housing for supplying power to actuate the subatmospheric pressure source.

Apparatus and method for treating a body joint wound subsequent to surgical intervention. An infusion tube is insertable into the wound for transporting a prepared solution to the joint. A second tube is insertable into the wound for transport of fluid removed from the joint. A vacuum device is coupled to the second tube. Suction is automatically turned on to evacuate the wound for a prescribed period of time and then stopped for another prescribed period of time. The on and off cycle may be repetitive. During the entire period, the prepared solution is constantly infused. The infusion tube and evacuation tube are isolated from each other so that no contaminants can be infused. A plurality of preadjusted suction duty cycles are available, from which one may be selected as appropriate for the type of wound to be treated.

An apparatus for drainage of a wound or surgical site of a human or animal fits anatomically, passes from inside the wound or surgical site percutaneously or covering an open wound surface and extends externally for accumulation of fluids. A plurality of fibers each with an internal end, middle and an external end is elongate with a thickness and a length wherein its thickness is substantially less than its length for flexibility. The fibers form a loose bundle with gathered external ends and with internal ends unrestrained for spreading divergently inside the wound or surgical site. A collector is positioned in fluid communication with the gathered external ends for accumulating bodily fluid guided along and amongst the fibers from the internal ends along the middle and to the external ends during drainage. Vacuum connects to draw fluid from the collector. A method has steps of providing fibers with the internal ends unrestrained, the external ends gathered in a collector to accumulate drained fluid. The method guides bodily fluid along and amongst the fibers from the internal ends along the middle and to the gathered together external ends during drainage. The fibers spread divergently for accumulating bodily fluid inside the wound or surgical site. A method of manufacture of the apparatus has the steps of accumulating a plurality of fibers with internal ends, a middle and external ends in a loose bundle but gathering together in a collector at their external ends while leaving the internal ends unrestrained.

A waste collection system for collecting waste during medical / surgical procedures including a mobile container cart with a waste container. A container cart is selectively coupled to a suction cart that includes a vacuum pump. The connection of the carts results in the connection of the vacuum pump to the waste container. The vacuum pump draws a vacuum that results in waste being drawn through a suction line into the waste container. The container cart holds instruments that can be removably attached to the container cart. This facilitates the configuration of the container cart for the specific procedure for which it is necessary to draw a suction.

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.
