A system and method is provided for healing a wound in a subject in need thereof. The system includes a wound dressing that has a therapeutic agent and at least one electrode in electrical communication with the therapeutic agent. The system also includes a power source in electrical communication with the at least one electrode and a vacuum source in fluid communication with the wound dressing.

The present invention provides a manually operated negative pressure wound treatment (NPWT) apparatus for suction of bodily fluids using the negative pressure generated by means of manual pressing. The NPWT apparatus is made of two parts: [1] top functional part; and [2] bottom collector part. The top functional part is made of a pressing mechanism attached to a bellow enclosed within an enclosure. The bellow is connected to the wound dressing using an external medical tube through a one-way check valve, wherein the negative pressure gets created within the bellows when compressed by manually pressing the mechanism. The negative pressure of the bellows sucks the bodily fluid from the wound, which promotes a new blood supply, cleaning infection, and accelerates healing dramatically. The bottom collector part is attached with the bellow through the internal one-way valve, wherein the collector collects the fluid from the bellow when the piston is pressed in the next cycle. Pressure levels and wound conditions are measured and transmitted to the user's smart device, in order to enhance treatment monitoring and efficacy.

In some embodiments, a negative pressure wound therapy system can detect and classify one or more operational conditions, including detection of a wound bleeding. The system can react to detection of blood by providing an indication, reducing the intensity or stopping therapy, releasing negative pressure, etc. In certain embodiments, the system can detect one or more additional operational conditions, such as change in vacuum pressure, gas leak rate change, exudate flow rate change, water flow rate change, presence of exudate, presence of water, etc. The system can detect and distinguish between different operational conditions and provide indication or take remedial action.

Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus may comprise a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus may further comprise an ambient port for providing the pressure sensor and the humidity sensor with access to the ambient environment providing readings relative to the atmospheric pressure and humidity.

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 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.

In some cases, a wound dressing includes a substantially flexible substrate with a first, wound-facing side supporting a plurality of electronic components and a second side opposite the first side, a wicking layer in contact with the second side of the substrate, the wicking layer configured to facilitate passage of fluid, a substantially non-stretchable coating applied to at least some of the plurality of electronic components, a substantially stretchable coating applied to the first side of the substrate, the stretchable coating applied over the substantially non-stretchable coating, a wound contact layer in contact with the stretchable coating, the wound contact layer configured to adhere to a wound, and a protective layer applied to the wound contact layer, the protective layer configured to be removed to expose the wound contact layer. In some cases, a method of manufacturing the wound dressing.

Embodiments of apparatuses and methods for determining an emplacement of sensors in a wound dressing are disclosed. In some embodiments, a wound dressing includes a plurality of sensors configured to measure wound or patient characteristics. One or more processors are configured to receive wound or patient characteristics data as well as emplacement data. The received data can be used to determine an emplacement of the plurality of sensors, the wound dressing, or a wound. The sensors can include a set of nanosensors. The wound dressing can include pH sensitive ink which can be utilized for determining a placement of the wound dressing and determining a pH associated with the wound. The wound dressing can be used in a negative pressure wound therapy system.

In some embodiments, a wound dressing that incorporates a number of sensors or sensors separate from the wound dressing can be utilized in order to monitor characteristics of a wound as it heals or to identify one or more risk factors or conditions that may precipitate a wound. In some implementations, a wound dressing configured to be positioned in contact with a wound includes a substantially flexible substrate supporting one or more sensors. The one or more sensors can include temperature sensors, conductivity sensors, multispectral optical measurements sensors, pH sensors, pressure sensors, colorimetric sensors, optical sensors, ultraviolet (UV) sensors, or infrared (IR) sensors.

The subject matter of the invention is a wound care device for treatment of wounds by means of subatmospheric pressure in the wound region, having a wound covering element, a device for generating subatmospheric pressure, which can optionally be placed on the wound covering element, and an absorption body taking up wound exudations.
