  • Publication number: 20200276367
    Abstract: One implementation of the present disclosure is a method for dynamically controlling an alarm of a negative pressure wound therapy (NPWT) device, according to some embodiments. In some embodiments, the method includes initiating NPWT, comparing an initial pump duty to a threshold value to determine a dressing application quality, monitoring a leakage rate of the NPWT, setting a leak threshold value based on the dressing application quality, determining leakage event occurrences in response to the leakage rate exceeding the leak threshold value at multiple times, adjusting the leak threshold value based on at least one of a number of the leakage events over the time period, a time duration between sequentially occurring leakage events of the leakage events, and the dressing application quality, and causing a user interface device to display a leak alert in response to the leakage rate exceeding the adjusted leak threshold value.

  • Publication number: 20200197008
    Abstract: A device includes a plurality of pneumatic modules and a pressure control device. The pneumatic modules are configured to attach to a patient's skin along edges of a wound and to translate a pneumatic pressure into a linear force. Each pneumatic module is configured to move between an extended position and a contracted position based on the pneumatic pressure within the pneumatic module. The pressure control device is configured to be pneumatically coupled to each of the pneumatic modules and configured to alternate the pneumatic modules between a first state and a second state. In the first state, the pneumatic pressure within a first set of the pneumatic modules is less than the pneumatic pressure within a second set of the pneumatic modules. In the second state, the pneumatic pressure within the first set of the pneumatic modules is greater than the pneumatic pressure within the second set of the pneumatic modules.

  • Publication number: 20200163803
    Abstract: Described herein are dressings comprising a composite island comprising a polyurethane or foam layer coupled to an absorbent layer comprising non-woven gelling fibers. Also described herein are dressings comprising an absorbent layer comprising carboxymethyl cellulose fibers and a backing layer coupled to the absorbent layer. In the respective dressings, the absorbent layer is not elastically deformable under tissue treatment conditions, whereas the polyurethane or foam layer and the backing layer are substantially elastically deformable under tissue treatment conditions. The coupling of the absorbent layer to the polyurethane/foam layer or backing layer renders the coupled structure or the entire dressing substantially elastically deformable under tissue treatment conditions. Methods of eliminating, minimizing, or reducing edema are also described herein.

  • Publication number: 20200139024
    Abstract: A tubeset module includes one or more elements of a negative pressure wound therapy (“NPWT”) system, such as a valve, a calibrated leak, a pressure sensor, etc. The tubeset module may communicate with a controller of the NPWT system via a communications interface provided by the tubeset module. The communication between the tubeset module and the controller may be used to fully automate one or more processes involving the operation of the components of the NPWT system included in the tubeset module, allowing the NPWT system to, e.g. estimate a wound site volume, estimate a volume of fluid to be instilled, monitor wound healing progression, etc. without requiring any user interaction or involvement. The tubeset module may be defined by one or more housing elements. The tubeset module may be incorporated into any of the tubing, fluid canister, wound dressing and/or therapy device housing components of the NPWT system.

    Abstract: A negative pressure wound therapy system includes at least one sensor coupled to a wound dressing for a wound of a patient, and a processing circuit. The at least one sensor is configured to output a measurement of the pressure in the wound dressing. The processing circuit is configured to open a sealable aperture, receive the pressure measurements in the wound dressing, calculate a rate of pressure decay, correlate the rate of pressure decay in the wound dressing to a wound dressing fluid absorbent capacity and other therapy parameters, and output the wound dressing fluid absorbent capacity and other therapy parameters to a remote electronic device.

  • Publication number: 20200038249
    Abstract: A pump generates a vacuum at a wound site via first tubing. A negative pressure circuit is defined by a canister, the first tubing and the wound site. A controller of a therapy device operates the pump to apply a first negative pressure to the entirety of the negative pressure circuit, following which ambient air is allowed to flow into the negative pressure circuit. The controller also operates the pump to apply a second negative pressure to a selected portion of the negative pressure circuit exclusive of the wound site, following which ambient air is allowed to flow into the selected portion. A quantity of fluid to be delivered to the wound site via a second tubing is determined by comparing measured parameters related to the flow of air into the negative pressure circuit to parameters measured with respect to the flow of air into the selected portion.

  • Patent number: 9814485
    Abstract: The present invention generally relates to devices and systems that utilize an inflatable bladder for generating, cutting, capturing, and/or transplanting one or more skin blisters. In some aspects, methods and devices in accordance with the present teachings can enable the harvesting of skin grafts from an increased variety of potential donor sites, such as areas of the body having uneven surfaces or a smaller radius of curvature (e.g., the arm) or large area donor sites where the creation of a vacuum may require a high power negative pressure source. In various aspects, systems, devices, and methods in accordance with the present teachings can also enable the efficient transplant of the grafts directly from the skin graft harvester to the recipient site without the transfer of the grafts generated by the harvester to another substrate prior to transplantation.
