Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly, canister, and a wound dressing configured to be positioned over a wound. The pump assembly, canister, and the wound dressing can be fluidically connected to facilitate delivery of negative pressure to a wound. The pump assembly can present graphical user interface screens for controlling and monitoring delivery of negative pressure. The system can be configured to efficiently deliver negative pressure and to detect and indicate presence of certain conditions, such as low pressure, high pressure, leak, canister full, and the like. Monitoring and detection of operating condition can be performed by measuring one or more operational parameters, such as pressure, flow rate, and the like.

A system and apparatus for treating a tissue site with reduced pressure and collecting fluids from the tissue site is disclosed. The system may include a reduced-pressure source, a pouch in fluid communication with the reduced pressure source, and a dressing in fluid communication with the pouch. The pouch may include a first wall, a second wall having a periphery coupled to the first wall to form an interior, and a third wall extending through the interior to form a first chamber in fluid communication with the dressing and a second chamber in fluid communication with the reduced pressure source. A plurality of filters are positioned in the third wall. The filters permit fluid communication between the first chamber and the second chamber.

A collecting unit, which receives secretion from a patient. The collecting unit comprises a cover (2) and a bag (3), which is mechanically connected to the cover (2). The bag (3) can be converted from a folded state, in which a portion of the bag (3) is folded about a fold axis (FA), into an unfolded state. Two overlapping overlap areas (3.1, 3.2) of the bag (3) that have each a connection area (VB.1, VB.2), are formed in the folded state. These connection areas (VB.1, VB.2) are detachably connected to one another, and preferably in a positively connected. The fold axis (FA) forms a common edge of the two overlap areas (3.1, 3.2).

A portable system for subatmospheric pressure therapy in connection with healing a surgical wound, includes a wound dressing dimensioned for positioning relative to a wound bed of a subject, a portable subatmospheric pressure mechanism dimensioned to be carried or worn by the subject and a container for collecting exudates from the wound bed removed under the subatmospheric pressure supplied by the subatmospheric pressure mechanism. The portable subatmospheric pressure mechanism includes a housing, a subatmospheric pressure source disposed within the housing and in fluid communication with the wound dressing to supply subatmospheric pressure to the wound dressing and a power source mounted to or within the housing for supplying power to actuate the subatmospheric pressure source.

The invention relates to a system for drainage of fluids or wound secretion from body and/or tissue openings of the human or animal body comprising a bag-like reservoir for collecting the fluid or wound secretion, with an upper inlet opening and a lower outlet opening, and a pre-evacuated container with an inlet opening, wherein the inlet opening of the pre-evacuated container is connected to the lower outlet opening of the bag-shaped reservoir.

The invention relates to a vacuum container for drainage of fluids or wound secretion, wherein the vacuum container is pre-evacuated, with an inlet opening for connection to a drainage line, wherein at the inlet opening a vacuum indicator is located and that the inlet opening is sealable. The invention further relates to a drainage line for drainage of fluids or wound secretion, wherein the drainage line has a vacuum indicator, wherein the vacuum indicator is designed to indicate a vacuum inside a connected vacuum container. Further the invention relates to a system for drainage of fluids or wound secretion, comprising a vacuum container according to the invention and a drainage line.

The present invention provides an assembly for urinary drainage. The assembly comprises a urinary drainage device for collecting urine from a body opening and a collecting bag for collecting the urine. The collecting bag comprises a compartment between sheets of a foil material and an inlet into the compartment, which inlet is connected to the device such that a urinary flow can be established in a flow path from the device through the inlet and into the compartment. The collecting bag further comprises a flow promoting element arranged between the sheets and having flow promoting properties. The collecting may also comprise suction means for providing suction through a flow path in the collecting bag.
