The described invention is a negative pressure wound therapy device designed for easy application to small to large wounds. The negative pressure device piece applies a vacuum to a wound and absorbs excess exudate or moisture. The negative pressure device comprises a sensor, battery, and small PCBA to monitor the pressure in the dressing and to alert a user when the dressing needs to be changed.

A wound treatment apparatus is provided for treating tissue damage, which comprises a fluid impermeable wound cover sealed over a site for purposes of applying a reduced pressure to the site. The apparatus also can include a cover with protrusions on its surface for purposes of monitoring pressure at the site. One or more sensors can be positioned under the cover to provide feedback to a suction pump controller. The apparatus can have a miniature and portable vacuum source connected to the wound cover.

Some embodiments have a pump assembly mounted to or supported by a dressing for reduced pressure wound therapy. The dressing can have visual pressure, saturation, and/or temperature sensors to provide a visual indication of the level of pressure, saturation, and/or temperature within the dressing. Additionally, the pump assembly can have a pressure sensor in communication with the flow pathway through the pump, and at least one switch or button supported by the housing, the at least one switch or button being accessible to a user and being in communication with the controller. The pump assembly can have a controller supported within or by the housing, the controller being configured to control an operation of the pump. The pump can be configured to be sterilized following the assembly of the pump such that all of the components of the pump have been sterilized.

A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system housed within or above a wound dressing member. The micropump system includes a miniature pump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed without the need for a cumbersome external vacuum source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used. The patient does not need to be constrained for any period of time while exudate is being removed from the wound.

One implementation of the present disclosure is a negative pressure wound therapy (NPWT) device. The NPWT device is configured to perform NPWT and includes a battery configured to supply the NPWT device with power, a pump configured to receive power from the battery and to produce a vacuum at a setpoint pressure to perform the NPWT, a user interface configured to provide alerts to a user, and a controller configured to receive power from the battery and to adjust the setpoint pressure of the pump. The controller is configured to operate the NPWT device in a standard therapy mode, a seal assist therapy mode, a pressure optimization mode, and a preservation mode of operation.

A negative pressure wound therapy device that includes a first tubing connectable in flow communication with a source of negative pressure configured for application of negative pressure to a wound site, a second tubing in flow communication with the wound site, and a valve.

A wound management system (WMS) is provided that includes dressings, bandages, or implantable medical devices that are equipped with filters, environmental controls, and sensors that promote the formation of a natural biologic seal between the skin and the dressing to form a barrier to microbial invasion into the body that accelerates healing and mitigates wound or exit site infection. Percutaneous access devices (PAD) used with the WMS or other devices including peritoneal dialysis (PD) catheters, Steinman pin, Kirschner wires, and chronic indwelling venous access catheters that require skin penetration. The WMS minimizes risk of exit site infection by reducing the bioburden in the exit tunnel environment in the acute and subacute phases of the PD catheter post-implant. Visualization of the wound without taking off the dressing is provided via a window in the wound area or exit-site to visually monitor for signs of infection and the presence of exudate.

Embodiments of negative pressure wound therapy devices and methods for controlling and operating such devices are disclosed. A negative pressure wound therapy apparatus can include a housing, a negative pressure source, controller, and output device supported by the housing. The negative pressure source can couple via a fluid flow path to a wound dressing and provides negative pressure to the wound dressing. The controller can operate the negative pressure source to provide negative pressure to the wound. The output device can provide identification data to an electronic device, and the identification data can be usable by the electronic device to access a label associated with the negative pressure wound therapy device.

A system and method for providing fluid to a tissue site is described. The method fluidly couples an instillation therapy system to the tissue site and monitors a pressure supplied to the tissue site by a reduced-pressure source with the instillation therapy system for a time period. The method provides fluid to the tissue site with the instillation therapy system in response to the pressure at the tissue site during the time period. The system includes a pressure sensor fluidly coupled to the tissue site to measure a pressure proximate the tissue site. A valve and a flow meter are fluidly between a fluid reservoir and the tissue site. A controller is communicatively coupled to the pressure sensor and the valve and configured to monitor the pressure at the tissue site and a volume of fluid flow to the tissue and, in response, operate the valve.

Disclosed herein is a device which is intended to deliver and maintain reduced pressure to body surfaces for application of reduced pressure wound therapy (RPWT) also known as negative pressure wound therapy (NPWT). During application of this type of therapy, a substantially airtight seal is formed around a section of tissue to be treated. This seal is formed by a dressing which provides fluid communication from a section of tissue to a reduced pressure source. Disclosed herein is a dressing system which is configured to enhance usability and functionality of this dressing. First, the system may be configured to allow full rotation of the fluid communication conduit to the reduced pressure source along the axis substantially normal to the dressing. Second, the system may be configured to include a one-way valve to prevent backflow of any drainage fluids. Third, the system may be configured with transparent windows covered by opaque flaps to allow inspection through the dressing. Fourth, the system may be configured to include an indicator which visually makes clear whether reduced pressure is being applied or not. Fifth, the system is configured to minimize the profile of the dressing system.
