A system for applying suction to a wound is provided, including a suction source for providing suction to a conduit operatively associated with the wound to communicate suction to the wound, a vent in fluid communication with the conduit to provide a reference airflow into the conduit when the system is in operation, such that a loss of suction at the wound is indicated by deviation from the reference airflow, and a waste collector canister between the wound and the suction source for collecting liquids aspirated from the wound, wherein the canister includes one or more disks containing gelling agent.

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

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

A pump system for applying negative pressure to a wound, including a flow monitor capable of detecting a deviation from a reference airflow rate provided by a controlled leak to determine whether the system is operating normally or abnormally, and a flow status annunciator to indicate a normal operating condition or whether an abnormal condition is a leak or an occluded line in the system. The pump system further includes a pressure controller for regulating operation of a pump to control pressure in the system at a range around a user-selected setpoint. The pump system may also include a waste collector and a level sensor for detecting when the collector is full.
