An integrated system for assessing wound exudates from the wound of a patient is described. The system may contain functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may means for comparing the one or more detected physiological values to predetermined physiological values in order to obtain a comparison result in real time. The system may include a processor 15 which provides an electronic signal based on a comparison result in which the electronic signal may correspond to guidelines for treating the wound 13. The system may be integrated with other wound treatment devices, such as negative pressure wound therapy devices (NPWT) 9.

Disclosed herein are systems and methods for providing reduced or negative pressure, and more particularly cyclical reduced pressure, to treat a wound. The system can include a wound dressing, a fluid collection container, a suction source, filters, and conduits. In addition, the system can include a control device and sensors. The sensors may be configured to monitor certain physiological conditions of a patient such as temperature, pressure, blood flow, blood oxygen saturation, pulse, cardiac cycle, and the like. Application of cyclical reduced pressure between two or more values below atmospheric pressure may be synchronized with the physiological conditions monitored by the sensors. Certain embodiments of the system utilize an air reservoir and one or more valves and pressure sensors or gauges to allow for rapid cycling of the level of reduced pressure within the wound dressing between two or more reduced pressure values.

A sampling interface may comprise an inlet port, an outlet port, and a sampling chamber between the inlet port and the outlet port. The apparatus may also comprise a sampling port and at least one split seal between the sampling port and the sampling chamber. The split seal may comprise a first sealing member and a second sealing member that converge to a sealing line. The apparatus may additionally include at least one fluid collection channel disposed interior to the split seal. A lateral flow strip for sampling fluid removed from a tissue site may comprise an acquisition surface and a migration medium fluidly coupled to the acquisition surface. At least one test medium may be fluidly coupled to the migration medium, and a liquid-impermeable cover may enclose the migration medium and the test medium. The acquisition surface is preferably not enclosed.

A negative pressure wound therapy system includes a wound dressing, at least one pump fluidly coupled to the fluid interface, a pressure sensor fluidly coupled to the wound dressing, a control housing, and an electrical coupler. The wound dressing includes a sealing layer, an absorbent layer adjacent to the sealing layer, and a fluid interface attached to at least one of the sealing layer or the absorbent layer. The at least one pump is configured to apply negative pressure to the fluid interface to draw fluid from the wound dressing via the fluid interface. The pressure sensor is configured to detect a fluid pressure of the wound dressing. The control housing is remote from the wound dressing. The electrical coupler is configured to removably connect the control housing to the at least one pump.

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.

Methods, apparatuses, and systems for promoting re-epithelialization as an aspect of wound healing are presented. A re-epithelialization dressing for use with reduced pressure has a moist tissue-interface layer, a manifold member, and a sealing member. The moist tissue-interface layer has a plurality of apertures. The moist tissue-interface layer is for disposing adjacent to the wound and provides a moisture balance (i.e., provides moisture when the wound is dry and receives moisture when the wound site is substantially wet). The reduced pressure, apertures, and moist tissue-interface layer help with liquid management and otherwise promote re-epithelialization. Other systems, apparatuses, and methods are presented.

This disclosure includes wound dressings and systems with low-flow, high-concentration therapeutic gas sources for topical wound therapy and related methods. Some dressings, which are configured to be coupled to tissue to facilitate delivery of therapeutic gas to the tissue, comprise a manifold that defines a plurality of gas passageways, the manifold configured to allow communication of therapeutic gas to the tissue; a sorbent material configured to be disposed above or below the manifold and to capture exudate; and a gas-occlusive layer configured to be disposed over the manifold and the sorbent material and coupled to the tissue such that an interior volume containing the manifold and the sorbent material is defined between the gas-occlusive layer and the tissue and the gas-occlusive layer limits escape of therapeutic gas from the interior volume.

A system and apparatus for the collection of serous or serosanguinous fluid from a percutaneous site after surgery. A pump unit with one or more pumps or powered sources provide continuous negative pressure suction to draw fluid from the percutaneous site and pumps the fluid into disposable reservoirs with one-way valves that are easy to handle while maintaining sterility and a seal to prevent the loss of vacuum. Air is continuously removed from the reservoirs. Measurement and analysis of the output is performed automatically.

An assembly includes a drape substantially sealable over a wound bed and a trackpad configured to couple a tube to the drape and allow the tube to provide suction to the wound bed. The assembly also includes a vent opening in the drape, a filter coupled to the drape and communicating with the vent opening, a cover coupled to the drape and movable between a first position to cover the vent opening and filter and a second position to uncover the vent opening and the filter, and a fluid indicator coupled to the drape and operable to provide a visual indication that fluid build-up is present in the wound bed.
