Wound dressing and method of treatment
A wound dressing, a method of manufacturing a wound dressing, and a method of treating a patient are disclosed. The wound dressing may include an absorbent layer for absorbing wound exudate; and an obscuring element for at least partially obscuring a view of wound exudate absorbed by the absorbent layer in use.
WOUND DRESSING SYSTEM, MONITOR DEVICE AND RELATED METHODS
A monitor device (4) for a wound dressing system the device comprising a processor; a memory; a first interface connected to the processor and the memory, configured for collecting wound data from a wound dressing (2), the wound data comprising wound data from different sensor points of the wound dressing; and a second interface. The processor configured to: obtain parameter data based on the wound data; and determine an operating state of the wound dressing based on the parameter data, wherein the operating state is indicative of a degree of wetting of the wound dressing. The monitor device is configured to, in accordance with a determination that the operating state is a first operating state, transmit a first monitor signal comprising monitor data indicative of the first operating state via the second interface and, in accordance with a determination that the operating state is a second operating state, transmit a second monitor signal comprising monitor data indicative of the second operating state via the second interface.
WOUND DRESSING WITH SATURATION INDICATOR
Described herein are wound dressings comprising: an absorbent layer capable of absorbing a given volume of fluid and comprising a first sorption zone comprising a first density of fibers and a second sorption zone comprising a second density of fibers higher than the first density; a hydrophilic foam layer coupled to the absorbent layer; and a backing layer extending beyond the absorbent layer and the hydrophilic foam layer to define a backing layer margin, wherein, upon exposure of the absorbent layer to a saturation threshold of wound exudate, the first sorption zone expands to a first thickness and the second sorption zone expands to a second thickness that is visually distinguishable from the first thickness. Methods of manufacturing the wound dressing and of eliminating, minimizing, or reducing edema are also described herein.
RESTRICTION OF SENSOR-MONITORED REGION FOR SENSOR-ENABLED WOUND DRESSINGS
A wound dressing that incorporates a number of sensors 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. The wound dressing can include at least one sensor, such as an impedance sensor, that may be restricted from sensing in a direction away from the wound when the wound dressing is positioned in contact with the wound.
COMPRESSION STRAIN AND NEGATIVE PRESSURE DELIVERY INDICATOR FOR A WOUND DRESSING
An indicator configured to be attached to a wound dressing includes first and second parts. The wound dressing is configured to collapse in response to an applied negative pressure. The first and second indicator parts are configured to move relative to one another as the wound dressing is collapsed. The movement of the first and second indicator parts is configured to allow a user to easily visualize the compression of the wound dressing and monitor the application of the negative pressure to the wound dressing. A marker is provided along a top surface of the first part and a window is formed on the second part. The changes in the portion of the marker that is visible in the window as the first part is slid into or under the second part are configured to provide for easier detection of the collapse of the wound dressing by the user.
NPWT SYSTEM WITH SELECTIVELY CONTROLLABLE AIRFLOW
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.
Evaporative fluid pouch and systems for use with body fluids
An inline storage-and-liquid-processing pouch for use with body fluids from a patient is presented that involves introducing body fluids into a first chamber in the storage-and-liquid-processing pouch and flowing air through a second chamber. The chambers are separated by a high-moisture-vapor-transfer-rate member. The air flow in the second chamber enhances liquid removal from the first chamber across the high-moisture-vapor-transfer-rate member. Other systems, devices, and methods are disclosed herein.
Head trauma bandage cap and method
An emergency hemostatic head trauma bandage cap with a strap system and method of use, which, when applied to the head, delivers minimal pressure to control bleeding, doesn't compromise cervical spine immobilization, allows for fast and effective application of cooling gel to control intracranial/internal swelling or hot packs to prevent hypothermia in non-trauma situations, doesn't come apart during treatment and transport, and doesn't require a caregiver to re-wrap the dressing.
LIQUID FLOW DETECTION IN TISSUE SITE DRESSINGS AND INSTILLATION METHODS
A dressing for treating a tissue site may include a manifold, a transparent or translucent backing layer disposed over a surface of the manifold, an adherent layer disposed on at least a margin of the backing layer, and a plurality of liquid contact indicators disposed in a spaced array between the manifold and the backing layer. A dressing kit may include the plurality of liquid contact indicators separate from the other elements of the dressing. Therapy systems may include the dressing or a dressing assembled from the dressing kit. Also, methods for monitoring fluid distribution and methods for reducing edema can include the dressing, a dressing assembled from the dressing kit, or at least a portion of the therapy system containing them.
WOUND DRESSING FOR WOUND VOLUME ESTIMATION
A wound therapy system includes a therapy unit, a wound dressing and an optional controller. The therapy unit is configured to deliver instillation fluid to a wound site. The wound dressing is formed from a plurality of discrete, individual blocks that are selectively separable from one another along a plurality of separation-lines, allowing the wound dressing to be customized to the shape and size of the wound site. By calculating the remaining blocks that define the wound dressing following customization, the volume of the wound dressing may be determined. The controller may be configured to deliver fluid to the wound site based on this calculated volume. The controller may also optionally be used to gauge the healing of the wound site over time by monitoring the changes in volume of customized wound dressings as wound dressings are replaced during the course of treatment of the wound site.
