摘要

The collector comprises: a collection bag (10) having a front end opening (11), a rear end opening (12) and a water resistant membrane (15) mounted in the front end opening to prevent a back flow; and a gas-permeable unit, where each of the gas-permeable unit is attached to a corresponding side of the collection bag; a through opening (13) by the corresponding side of the collection bag; a gas-permeable membrane mounted at the inner side of the side and covers the through opening; a liquid absorber mounted in the collection bag; an inflow connection set. The collector comprises: a collection bag (10) having a front end opening (11), a rear end opening (12) and a water resistant membrane (15) mounted in the front end opening to prevent a back flow; and a gas-permeable unit, where each of the gas-permeable unit is attached to a corresponding side of the collection bag; a through opening (13) by the corresponding side of the collection bag; a gas-permeable membrane (14), which is mounted at the inner side of the corresponding side and covers the through opening; a liquid absorber mounted in the collection bag; an inlet connection kit that is mounted in the front end opening of the collecting bag; and a outlet connection kit formed in the rear end opening of the collecting bag. The outlet connection kit has a gas-permeable connection, which is introduced into the rear end opening. The liquid absorber is securely attached to the collection bag, and is formed in a U-shaped cross-section. The inlet connection kit includes: a connecting tube, which is inserted into the front end opening; and a connection that fits itself to the connecting tube. The collection bag comprises two gas-permeable units, which are separated and attached respectively to two sides lying opposite to the collection bag and are diagonally arranged. An independent claim is included for a collector combination for a negative pressure wound therapy system.
