Wound therapy device and related methods

A wound closure apparatus is disclosed which includes a housing that contains a vacuum pump and a chamber for holding a disposable wound fluid collection canister. The canister resides within the chamber and connects at an outlet with the vacuum pump and at an inlet with a pad. The pad is placed over a wound and adhesively secured thereto. When the vacuum pump activates, it evacuates air from the canister resulting in wound fluids flowing from the wound into the canister. After the canister is filled, it is removed from the chamber and replaced with another canister to continue the removal of wound fluids.

System for treating a wound with suction and method of detecting loss of suction

A system for applying suction to a wound uses a reference airflow for monitoring system operation. A reference airflow (or “controlled leak”) to the suction source is provided when the system is in operation, such that deviation from the reference airflow can be monitored as an indication of a change in operation, such as a leak in the seal of the wound cover, a blockage of airflow from crimping of the suction conduit or overfill of the waste collector, or an inadvertent turn off or disconnect from the suction source.

Fluid exchange system for controlled and localized irrigation and aspiration

The control of fluid introduction into and out of body conduits such as vessels, is of great concern in medicine. As the development of more particular treatments to vessels and organs continues it is apparent that controlled introduction and removal of fluids is necessary. Fluid delivery and removal from such sites, usually referred to as irrigation and aspiration, using fluid exchange devices that control also need to be considerate of potential volume and / or pressure in the vessel or organ are described together with catheter and lumen configurations to achieve the fluid exchange. The devices include several electrically or mechanically controlled embodiments and produce both controlled and localized flow with defined volume exchange ratios for fluid management. The applications in medicine include diagnostic, therapeutic, imaging, and uses for the introduction or removal of concentrations of emboli within body cavities.

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.
