摘要:
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.
摘要:
A system for treating a wound with suction is provided. The system comprises a wound cover, a pump having an input port and an output port, the input port providing suction to the wound via the wound cover, and a reservoir coupled to the output port of the pump. The reservoir is adapted to receive effluent from the wound and the pump is capable of maintaining a controlled level of suction at the wound.
摘要:
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.
摘要:
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.

Disclosed are methods of leasing or billing for the usage of a portable suction pump adapted for use in a suction-assisted would treatment system. The pump has means for recording time units corresponding to periods of time when the pump is operating and for providing reports of usage time. The pump further has means for detecting that the wound treatment system is operating normally so as to be compliant with standards for suction wound treatment, and for recording and reporting time of normal operation or compliant usage. The methods include leasing the pump at a payment schedule that is based upon the amount of actual usage time or the amount of compliant usage time. The lease payment may include an amount of pre-paid time units such that unused time units can be credited to a new or renewed lease for a replacement pump. The billing methods can also be based in whole or in part on a planned maintenance schedule for the pump.
摘要:
The invention provides a vacuum tube attachment device for vacuum assisted wound dressings. The device is in the form of a patch that can be attached to the primary wound cover. The patch forms a substantially air-tight seal to the primary wound cover, and a vacuum tube is fixed to the patch such that the patch can be oriented on the wound cover to locate the tube near an opening in the cover to allow vacuum pressure to be communicated to the wound. The patch has an adhesive area around its perimeter for attaching the patch in a substantially air-tight seal to the wound cover at any convenient location on the cover. Several embodiments of the patch are described.
