A portable drain system having a subdermal drain and a container in fluid communication with the subdermal drain is disclosed. The subdermal drain is configured to drain fluid from a surgical site. The container provides a negative pressure to the subdermal drain. The container draws and receives the fluid. The container includes at least one sensor in which the at least one sensor is configured to detect at least one of fluid color, fluid volume in the container, and orientation of the container.

A fluid drainage device which includes a fluid-receiving volume, a cover which is movable between a first limiting position at which an inlet port is in fluid communication with the volume and a second limiting position at which an outlet port is in fluid communication with the volume, a piston which is movable inside the volume between a first position and a second position, a handle which is moveable in a first direction to cause the piston to move to the first position and to store energy in a spring so that, when the cover is in the first limiting position the piston is moveable by energy released from the spring to reduce pressure in the volume, allowing fluid flow through the inlet port, and wherein movement of the handle in a second direction causes the piston to move to the second position thereby expelling fluid from the volume.

A negative pressure wound treatment system comprising a bandage portion and a negative pressure portion. The bandage portion includes a dressing portion in contact with a wound and a sealing layer positioned in contact with the dressing portion. The sealing layer includes an adhesive creating a seal around the wound. The negative pressure portion is in fluid communication with the bandage portion and includes a first valve and a second valve. The first valve is in fluid communication with the bandage portion and the negative pressure portion. The second valve is in fluid communication with the negative pressure portion and the surrounding environment. The negative pressure wound treatment system is configured to provide negative pressure to an area sealed by the bandage portion upon the actuation of the negative pressure portion. The negative pressure portion is configured to be actuated by compressing the negative pressure portion while walking.

An apparatus and method for collecting fluid are disclosed. The apparatus includes a body portion comprising a fluid inlet and an outlet, an expandable container secured to the body portion, at least one wicking element extending from within the body portion into the container, and at least one super absorber element arranged inside the container.

A collection fitting, system, and method for sampling fluid from a tissue site is described. The collection fitting includes a switch fitting having a first passage and a second passage. The collection fitting also includes a bypass switch coupled to the switch fitting. The bypass switch is operable to fluidly couple the first passage and the second passage through the bypass switch. The bypass switch is also operable to fluidly couple the first passage and the second passage through a specimen container.

A fluid collection apparatus for use in negative pressure wound therapy. The fluid collection apparatus includes a flexible bag having a first opening and a second opening. The bag includes a structure defining a fluid pathway connecting the first opening and the second opening. The pathway is circulative and contributes to orientation independence of the bag in use. The bag further includes a load-bearing component.

Embodiments of negative pressure wound therapy systems and methods are disclosed. In some embodiments, a wound therapy system includes a negative pressure source configured to provide negative pressure via a fluid flow path to a wound dressing, a first circuit board assembly including a first controller configured to control a wound therapy with the wound dressing by activation and deactivation of the negative pressure source, and a second circuit board assembly in communication with the first circuit board assembly, the second circuit board assembly separate from the first circuit board assembly. The second circuit board assembly can include a second controller configured to wirelessly communicate therapy data via a communication network, receive an executable command from an electronic device, and execute the executable command without providing the executable command to the first controller.

A negative pressure wound closure system and methods for using such a system are described. Preferred embodiments of the invention facilitate closure of the wound by utilizing a stabilizing structure that preferentially contracts to provide for movement of the tissue. Some embodiments may utilize a protective layer, such as a mesh or net layer, attached to a top surface of the stabilizing structure. The protective layer prevents a drape positioned over the stabilizing structure from being drawn into cells of the stabilizing structure, and permits visualization of the collapse of the cells.

A wound therapy system includes an instillation fluid canister configured to contain an instillation fluid, a pump fluidly coupled to the instillation fluid canister and operable to deliver the instillation fluid from the instillation fluid canister to a wound, a user interface configured to receive user input indicating one or more geometric attributes of the wound, and a controller electronically coupled to the pump and the user interface. The controller is configured to determine a volume of the wound based on the user input, determine a volume of the instillation fluid to deliver to the wound based on the volume of the wound, and operate the pump to deliver the determined volume of the instillation fluid to the wound.

A treatment system for applying negative pressure to a tissue site in conjunction with a venting or purging capability. In some embodiments, the treatment system may include a reduced-pressure source, an inline storage pouch, a purge chamber, and a dressing. Reduced-pressure may be supplied to the inline storage pouch and the dressing, while the purge chamber may provide a ventilation opening to the atmosphere.
