Abstract
The invention provides an exudate collecting box for a negative-pressure therapy system. The exudate collecting box comprises an exudate collecting box shell, a negative-pressure connector and a dressing connector, wherein the negative-pressure connector is arranged on the upper half portion of the shell and connected with a negative-pressure source gas path, and the dressing connector is arranged on upper half portion of the shell and is connected with a dressing assembly. An isolation baffle provided with through holes is further disposed in the shell and isolates the negative-pressure connector from wound exudates. The isolation baffle is disposed between the negative-pressure connector and the dressing connector. The isolation baffle used for isolating the negative-pressure connector from the wound exudates is arranged in the exudate collecting box and independently isolates the negative-pressure connector, the through holes formed in the isolation baffle guarantee good air permeability between the negative-pressure connector and the dressing connector, and the size of the aperture of the through holes allows exudates to form an exudate film through surface tension when the exudates flow through the through holes, so that the situation that when the exudate collecting box falls, the wound exudates flow into the negative-pressure connector, affect therapy and harm patients is prevented.
