Abstract
Connectors and devices for flexible negative pressure systems are described.
Claims20
A device for use in negative pressure wound therapy comprising:
- a) a first compartment comprising a first connection site, and
- b) a connector comprising an air inlet and an air outlet connected by an air pathway, wherein the air outlet is connectable to the first connection site, wherein the connector is further selected from:
- i) a first connector, wherein the air inlet of the first connector is connectable to a first fluid retention source;
- and
- ii) a second connector further comprising a fluid inlet and a fluid outlet connected by a fluid pathway, wherein the air inlet and the fluid outlet of the second connector are connectable to a second fluid retention source, and the fluid inlet connectable with a transfer dressing or a fluid retention dressing;
- wherein the first connector and second connector interchangeably connect to the first connection site of the device.
3 more elements
A method for replacing a fluid retention source during negative pressure wound therapy, the method comprising:
- a) obtaining
- i) a control unit comprising a source of negative pressure, a first connection site in fluid communication with the source of negative pressure, a sensor, and a second connection site in communication with the sensor;
- ii) a first connector connected to the first connection site and the second connection site of the control unit;
- and
- iii) a first fluid retention source connected to the first connector;
- b) disconnecting the first connector from the control unit and the first fluid retention source, in either order;
- c) connecting a second connector to:
- a second fluid retention source, and the first connection site and the second connection site of the control unit;
- wherein the second connector is connected to the second fluid retention source and control unit in either order;
- wherein the first connector and the second connector each comprise an air outlet and an air inlet connected by an air pathway, and a sensor outlet and a sensor inlet connected by a sensor pathway;
- wherein the first connection site of the control unit is connected to the air outlet of the first connector in step (a) and the air outlet of the second connector in step (c);
- wherein the second connection site of the control unit is connected to the sensor outlet of the first connector in step (a) and the sensor outlet of the second connector in step (c);
- and
- wherein the first fluid retention source is connected to the air inlet of the first connector in step (a), and the second fluid retention source is connected to the air inlet of the second connector in step (c).
