Systems and methods for reduced pressure tissue treatments, including a multi-orientation canister. The canister includes an inlet for receiving fluids from a tissue site, and a main chamber in fluid communication with the inlet for receiving fluids from the inlet. The canister includes a filter chamber separated from the main chamber by one or more filter chamber walls. The one or more filter chamber walls includes a primary hole having a first diameter and a secondary hole having a second diameter smaller than the first diameter. The primary hole provides a first path of fluid communication between the filter chamber and the main chamber. The canister includes an outlet for providing fluid communication between the filter chamber and a reduced pressure source.

A reduced-pressure canister includes a canister body having a fluid reservoir, an inlet for receiving fluids from a patient, and an integral hydrophobic filter formed within a side or top portion of the canister body. The integral hydrophobic filter has a plurality of pores in the canister body that are covered by a hydrophobic coating. Other canisters, methods, and systems are also presented.

A system, method, and apparatus for treating a tissue site with reduced pressure includes a dressing adapted to be positioned proximate the tissue site. An absorbent may be adapted to be fluidly coupled to the manifold, and an ion exchange member may be adapted to be fluidly coupled between the manifold and the absorbent. A sealing member may be adapted to cover the tissue site to form a sealed space having the manifold disposed therein. A reduced-pressure source may be adapted to be fluidly coupled to the manifold.

Disclosed herein are devices, systems and methods for using such devices and systems for treating incisions and wounds. In an aspect, disclosed is a device having a generally planar tension relief module and a flexible sealant structure sized to cover the tension relief module, the flexible sealant structure comprising a lower adhesive surface. The tension relief module includes a conduit structure having a plurality of support structures on an upper surface of the conduit structure and at least one opening extending through the conduit structure from a lower surface to the upper surface. At least a portion of the conduit structure is adapted to be aligned with a longitudinal axis of the incision. The tension relief module also includes opposing adhesive structures coupled to the conduit structure. The lower adhesive surface of the flexible sealant structure and the upper surface of the conduit structure form a flow pathway.

A system and method of collecting and disposing of fluid during a medical procedure. Fluid is drawn from a fluid source into a first reservoir in communication with a vacuum source. The fluid passes through an open fluid transfer valve into a second reservoir in communication with the vacuum source. While the fluid continues to be drawn into the first reservoir, the fluid transfer valve is closed after a predetermined volume of the fluid passes into the second reservoir. The fluid collected in the second reservoir is measured and evacuated from the second reservoir. The fluid transfer valve is opened and the steps are repeated until the medical procedure is completed while the first reservoir remains in uninterrupted communication with the vacuum source during the medical procedure such that fluid is capable of continuing to be drawn into the first reservoir without interruption.

A collection liner for a medical or a surgical operation includes a closed flexible bag portion. The closed flexible bag portion has a width direction (W) and a length direction (L). The closed flexible bag portion includes an upper part of the bag portion in the length direction and a lower part of the bag portion in the length direction. The lower part of the bag portion is folded inside the upper part of the bag portion in such a manner that the entire lower volume of the lower part is upside down inside the upper part.

A device for the jellification/absorption of a water-based fluid, said device comprising a) at least one member comprising at least one absorption material and at least one jellifying agent, and b) at least one container, wherein the at least one jellifying agent is adapted to react with the water-based fluid to form a gel; wherein the at least one member is contained within the at least one container, and wherein the at least one container is made, at least in part, of a water-soluble material. A method for the manufacture of the device and a use of the device.

Systems and methods for reduced pressure tissue treatments, including a multi-orientation canister. The canister includes an inlet for receiving fluids from a tissue site, and a main chamber in fluid communication with the inlet for receiving fluids from the inlet. The canister includes a filter chamber separated from the main chamber by one or more filter chamber walls. The one or more filter chamber walls includes a primary hole having a first diameter and a secondary hole having a second diameter smaller than the first diameter. The primary hole provides a first path of fluid communication between the filter chamber and the main chamber. The canister includes an outlet for providing fluid communication between the filter chamber and a reduced pressure source.

A wound therapy device is disclosed. The wound therapy device may include a housing for covering at least a portion of a wound and for sealing to a body surface of a patient. The housing may also include a liquid collector for retaining liquid therein and a vacuum connection for coupling to a vacuum source. The vacuum connection may be in gaseous communication with the liquid collector. The vacuum connection may be separated from the liquid collector by a liquid barrier.

A bodily fluid collection system may include a canister fluidly connected to a dressing at a tissue site through an inlet. The canister may also be fluidly connected to a reduced pressure source through an outlet. At least a portion of the wall of the canister may be a membrane and may have the open edge of a flexible bag container fixed to the canister surrounding the perimeter of the membrane. The flexible bag may contain an osmotic agent capable of drawing absorbent from bodily fluid in the canister through the membrane and into the flexible bag.
