Abstract
An apparatus () for negative pressure wound therapy comprises a source of reduced pressure () and first () and second () chambers, the first chamber being in fluid communication with the source of reduced pressure such that a negative pressure may be generated in the first chamber, the negative pressure being prevented from exceeding a predetermined value by way of a pressure release means (), and the second chamber comprising means () for establishing a fluid connection with a wound. A valve () between the first and second chambers permits the negative pressure in the second chamber to increase in response to an increase in the negative pressure in the first chamber and prevents the negative pressure in the second chamber from dropping in response to a drop in the negative pressure in the first chamber.
