[0002] DETAILED DESCRIPTION OF THE INVENTION The embodiments described herein relate to devices, systems, and methods for treating wounds, for example, using dressings in combination with negative pressure wound therapy. [Background technology]

[0003] Topical negative pressure (TNP) therapy, sometimes referred to as vacuum-assisted closure therapy, negative pressure wound therapy, or reduced pressure wound therapy, is widely recognized as a beneficial mechanism for improving wound healing rates.

[0014] overview Consistency of care can be important when treating difficult-to-heal wounds. For example, consistency in the intervals between dressing changes for treating a wound can affect the rate at which the wound heals.

[0015] A healthcare professional's ability to triage a wound may traditionally be limited to visual inspection of the wound and its adjacent area during a dressing change. However, the features disclosed herein, in certain implementations, may enable a healthcare professional to visualize and understand the characteristics of a wound and its adjacent area through visual inspection of the wound or its adjacent area and without removing the wound dressing covering the wound. This may enable a healthcare professional to assess a wound through a familiar visual review of the area surrounding the wound, regardless of whether a wound dressing may be covering the wound.

[0016] Information about the wound can be presented at the point of care (POC) as a graphical representation of data detected from or determined about the wound or its adjacent area, according to features disclosed herein. The data can be detected or determined from one or more sensors (e.g., one or more accelerometers, gyroscopes, magnetometers, impedance or conductivity sensors, perfusion sensors, thermostats, pH sensors, pressure sensors, or optical sensors, among other types of sensors) integrated into the wound dressing or positioned proximate the wound or wound dressing. The graphical representation can be illustrated as being presented or fixed proximate to the wound so that the data can be shown to the healthcare professional in the context of the wound area, which can help leverage the healthcare professional's experience in assessing wounds by viewing the area near the wound.

[0017] The graphical representation may be shown in the form of an augmented reality (AR) overlay on or around the wound dressing, which may be presented by a head-mounted display (HMD), a mobile device, form projection technology, or another type of display. The graphical representation may be a heat map, which uses color coding of the data to visually represent different values ​​of the data. The heat map may include a number of heat map levels, where each heat map level may represent a different data set (e.g., temperature, conductivity, pH, etc.) detected or determined around the wound or its adjacent area. The relative position or opacity of the heat map levels may be adjusted by a healthcare professional to facilitate comparison of different data sets, among other features.

[0018] The graphical representation can present information in real time or substantially real time as detected from or determined about the wound or its adjacent areas, thus allowing the medical professional to understand the current environment at the wound. Alternatively, the graphical representation can present information under the control of user-adjustable media interface elements (e.g., play / pause buttons, rewind buttons, fast-forward buttons, etc.), which can be used to navigate the wound environment over time and aid in understanding the information in both locational and temporal contexts.

[0019] The position of the graphical representation may be aligned or fixed relative to one or more features of or around the wound (e.g., one or more skin spots, one or more wound perimeter features, the shape of the wound, the shape of the wound dressing, the position of the wound dressing, or one or more markings on the wound dressing) from the perspective of the medical professional. Thus, one or more features of or around the wound may serve as one or more fiducial markers (sometimes referred to as alignment markers) to facilitate precise positioning of the graphical representation and further enable automatic adjustments to the positioning in response to changes in position, velocity, or distance between two or more of the multiple fiducial markers, such that the graphical representation may appear fixed from the perspective of the medical professional. Because the resolution of the graphical representation may exceed the granularity of the data detected from or determined about the wound, values ​​of the data detected from or determined about the wound may be calculated (e.g., interpolated) to enhance the resolution of or smooth transitions in the graphical representation.

[0020] The features disclosed herein, in certain implementations, may be desirable not only to assist a healthcare professional in correctly manually placing a wound dressing or one or more other components in a care environment, but also to quantify discrepancies in incorrect placement of the wound dressing or one or more other components. The wound dressing or one or more other components may include one or more sensors or one or more fiducial markers, which can be used in combination with an electronic device and potentially one or more other sensors to monitor the position of the wound dressing or one or more other components. The position of the wound dressing or one or more other components relative to the wound can be used to generate instructions to a user to guide the correct movement of the wound dressing or one or more other components. This can facilitate consistent placement of the wound dressing or one or more other components, allowing for consistent data generation by the wound dressing or one or more other components, or allowing for data generation by inconsistent placement that is post-processed to maintain longitudinal or latitudinal consistency.

[0021] Wound dressing placement and wound monitoring Some aspects disclosed herein relate to devices and methods for monitoring or treating biological tissue using sensor-enabled substrates. The sensor-enabled technology disclosed herein has broad application to any type of therapy that can benefit from a sensor-enabled substrate and can be utilized to collect data that medical professionals can rely on to make both diagnostic and patient management decisions.

[0022] The data collected by the sensor-enabled substrate, before or after further processing by the processor, may be presented by an augmented reality (AR) display. The information presented by the AR display may be overlaid on an area proximate to the sensor-enabled substrate from the perspective of a healthcare professional, such that the information can be perceived or understood by the healthcare professional in a relevant context.

[0023] The AR display can be used to guide the medical professional in manual placement of one or more components of a treatment or monitoring system, such as a sensor-enabled substrate. The AR display can indicate to the medical professional to move or reorient the sensor-enabled substrate to ensure a desired placement, such as, for example, consistent placement of the sensor-enabled substrate relative to previous placement of another sensor-enabled substrate on the wound.

[0024] The sensors may be mounted on or embedded within a substrate configured for use in the treatment of both intact and injured human or animal tissue. Such sensors may collect information about the surrounding tissue and transmit such information to a computing device or caregiver for use in further treatment. The sensors may be attached to the skin anywhere on the body, including areas for monitoring arthritis, temperature, or other areas prone to problems and requiring monitoring.

[0025] The sensor features disclosed herein may be incorporated into wound treatment or a variety of other applications, such as monitoring and treatment of intact skin, cardiovascular applications such as monitoring blood flow, orthopedic applications such as monitoring limb movement and bone repair, neurophysiological applications such as monitoring electrical impulses, and any other tissue, organ, system, or condition that can benefit from improved sensor-enabled monitoring.

[0026] Throughout this specification, reference is made to wounds. The term wound is broadly construed to include open and closed wounds in which the skin is torn, incised, or perforated, or traumatically induced contusion, or any other surface or other pathological or incomplete condition in a patient's skin, or others that would benefit from reduced pressure treatment. Thus, a wound is broadly defined as any damaged area of ​​tissue, which may or may not produce fluid. Examples of such wounds include, but are not limited to, abdominal wounds or other large or incisional wounds resulting from surgery, trauma, sternotomy, fasciotomy, or other conditions, dehiscence wounds, acute wounds, chronic wounds, subacute wounds and dehiscence wounds, traumatic wounds, flaps and skin grafts, lacerations, abrasions, contusions, burns, diabetic ulcers, pressure ulcers, stomas, surgical wounds, traumatic ulcers, and venous ulcers.

[0027] Embodiments of the systems and methods disclosed herein may be used in conjunction with topical negative pressure ("TNP") or reduced pressure therapy systems. Briefly, negative pressure wound therapy can assist in the closure and healing of many forms of "hard-to-heal" wounds by reducing tissue edema, promoting blood flow and granulation tissue formation, removing excessive exudate, reducing bacterial load (and therefore infection risk), and providing other benefits.

[0028] As used herein, a reduced or negative pressure level, such as −X mmHg, represents a pressure level relative to normal ambient atmospheric pressure, which may correspond to 760 mmHg (or 1 atm, 29.93 inHg, 101.325 kPa, 14.696 psi, etc.). Thus, a negative pressure value of −X mmHg reflects a pressure that is X mmHg lower than 760 mmHg, or in other words, a pressure of (760−X) mmHg. Additionally, a negative pressure “lower” or “less” than X mmHg corresponds to a pressure closer to atmospheric pressure (e.g., −40 mmHg is lower than −60 mmHg). A negative pressure “higher” or “greater” than −X mmHg corresponds to a pressure further from atmospheric pressure (e.g., −80 mmHg is higher than −60 mmHg). In some cases, the local ambient pressure is used as a reference point, and such local pressure need not necessarily be, for example, 760 mmHg.

[0029] The systems and methods disclosed herein may be used in addition to or instead of reduced pressure therapy, such as irrigation, ultrasound, heating or cooling, nerve stimulation, or the like. In some cases, the disclosed systems and methods may be used for wound monitoring without the application of additional therapy. The systems and methods disclosed herein may be used with dressings, including compression dressings, reduced pressure dressings, or the like.

[0030] FIG. 1 illustrates a wound therapy system 100 (sometimes referred to as a reduced pressure wound therapy system, negative pressure wound therapy system, TNP system, or wound treatment system) comprising a wound filler 130 disposed within a wound cavity 110, the wound cavity 110 being sealed by a wound cover 120. The wound filler 130 in combination with the wound cover 120 may be referred to as a wound dressing. A conduit 140 (such as a single-lumen or multi-lumen tube) may connect the wound cover 120 to a wound therapy device 150 (sometimes referred to in whole or in part as a pump assembly) configured to deliver reduced pressure or negative pressure. The wound cover 120 may be in fluid communication with the wound cavity 110. The wound therapy device 150 may be canister-less (meaning that exudate is collected in the wound dressing or transferred to another location for collection via the conduit 140) or may include or support a canister.

[0031] The wound therapy device 150 may be attached to or supported by a wound dressing, or may be adjacent to the wound dressing. The wound filler 130 may be of any suitable type, such as hydrophilic or hydrophobic foam, gauze, an inflatable bag, etc. The wound filler 130 may conform to the wound cavity 110 so that it substantially fills the cavity 110. The wound cover 120 may provide a substantially fluid-impermeable seal over the wound cavity 110. In some cases, the wound cover 120 may have an upper side and a lower side, with the lower side adhesively (or in any other suitable manner) sealing the wound cavity 110. The conduit 140, or other conduits disclosed herein, may be formed from polyurethane, PVC, nylon, polyethylene, silicone, or any other suitable material.

[0032] Wound cover 120 may have a port (not shown) configured to receive an end of conduit 140. In some cases, conduit 140 may otherwise pass through or under wound cover 120 to supply reduced pressure to wound cavity 110 so as to maintain a desired level of reduced pressure within wound cavity 110. Conduit 140 may be any suitable article configured to provide an at least substantially sealed fluid flow path or passageway between wound therapy device 150 and wound cover 120 so as to supply reduced pressure provided by wound therapy device 150 to wound cavity 110.

[0033] The wound cover 120 and wound filler 130 may be provided as a single item or an integral single unit. In some cases, no wound filler is provided, and the wound cover 120 itself may be referred to as the wound dressing. The wound dressing may then be connected to a source of negative pressure in the wound therapy device 150 via a conduit 140. In some cases, although not necessary, the wound therapy device 150 may be miniaturized and portable, although larger conventional such pumps may also be used.

[0034] The wound cover 120 may be positioned over the wound site to be treated. The wound cover 120 may form a substantially sealed cavity or enclosed space over the wound site. The wound cover 120 may have a film with high water vapor permeability to allow evaporation of excess fluids and may have a superabsorbent material contained therein to safely absorb wound exudate. In some cases, the components of the TNP system described herein may be particularly suitable for incisional wounds that exude a small amount of wound exudate.

[0035] The wound therapy device 150 may include a pressure source, such as a source of negative pressure. The wound therapy device 150 may deliver a negative pressure of approximately -80 mmHg, or between about -20 mmHg and -200 mmHg. Note that these pressures are relative to normal ambient atmospheric pressure; that is, -200 mmHg may practically be approximately 560 mmHg. In some cases, the pressure range may be between approximately -40 mmHg and -150 mmHg. Alternatively, a pressure range of -75 mmHg or less, -80 mmHg or less, or greater than -80 mmHg may be used. Also, in some cases, a pressure range below -75 mmHg may be used. Alternatively, a pressure range of approximately -100 mmHg or even greater than -150 mmHg may be delivered by the wound therapy device 150. The wound therapy device 150 can provide continuous or intermittent negative pressure therapy.

[0036] In operation, wound packing 130 may be inserted into wound cavity 110, and wound cover 120 may be placed to seal wound cavity 110. Wound therapy device 150 may provide negative pressure to wound cover 120, which may be transmitted to wound cavity 110 via wound packing 130. Fluid (such as wound exudate) may be drawn through conduit 140 and stored in a canister. In some cases, the fluid is absorbed by wound packing 130 or one or more absorbent layers (not shown).

[0037] The wound dressing can incorporate several electronic components, including one or more sensors or controllers, and can be utilized to monitor characteristics of or around the wound cavity 110. The electronic components can transmit sensor data or processed data, for example, wirelessly or via a wired connection, to one or more electronic devices that facilitate processing of the sensor data or processed data or visually present information in response to the sensor data or processed data. Collecting and analyzing data from the wound cavity 110 can provide useful insights into determining whether the wound is on a healing curve, selecting appropriate therapy, determining whether the wound has healed, etc.

[0038] Numerous sensor technologies can be used in or next to the wound dressing. For example, one or more sensors can be integrated into or on a substrate (such a substrate can be referred to as a "sensor-integrated substrate"). One or more sensors can be provided as a separate layer of material that is placed directly or indirectly on or in the wound cavity 110. The substrate can be part of a larger wound dressing device, such as part of a single unit dressing. Additionally or alternatively, the substrate can be placed directly or indirectly on or in the wound cavity 110 and then covered by a secondary wound dressing, which can include one or more of gauze, foam, or other wound packing material, a superabsorbent layer, a drape, a fully integrated dressing such as the Pico or Allevyn Life dressings manufactured by Smith & Nephew, and the like.

[0039] The substrate can be placed in contact with the wound cavity 110 and can allow fluid to pass through the substrate while causing little or no damage to the tissue within the wound cavity 110. The substrate can be flexible, elastic, stretchable, or stretchable, or substantially flexible, elastic, stretchable, or stretchable, to conform to or cover the wound cavity 110.

[0040] The substrate may support a plurality of electronic components and a plurality of electronic connections interconnecting at least some of the plurality of electronic components. The plurality of electronic components may be or may include one or more sensors, amplifiers, capacitors, resistors, inductors, controllers, or the like. The electronic connections may electrically connect one or more of the electronic components. The electronic connections may be tracks printed on the substrate, such as using copper, conductive ink (silver ink, graphite ink, etc.). At least some of the electronic connections may be flexible or stretchable, or substantially flexible or stretchable.

[0041] The multiple electronic components may be controlled by a control module, which may include a controller and a memory device. The control module may receive and process one or more measurements obtained by the one or more sensors. The control module may include one or more controllers or microprocessors, memory, etc. The control module may be positioned on, supported by, adjacent to, or remote from the wound dressing.

[0042] The wound dressings or wound dressing components described herein may be part of a kit that also includes a wound therapy device 150. One or more components of the kit, such as the substrate, secondary dressing, or wound therapy device 150, may be sterilized.

[0043] 2 illustrates a wound monitoring system 200 including a wound dressing 210, a monitoring device 220, and a display device 230 in communication with each other. The wound monitoring system 200 can facilitate the collection of sensor data from or around a wound covered by the wound dressing 210. The sensor data can then be passed to the monitoring device 220 or the display device 230 for processing, such as generating a graphical representation for presentation to a medical professional. Although the monitoring device 220 and the display device 230 are shown as separate in FIG. 2, the monitoring device 220 and the display device 230 may instead be a single combined device supported by a common housing, or may share one or more components, such that the monitoring device 220 or the display device 230 may have a particular component (e.g., a user interface or sensor) that the other does not have.

[0044] The wound dressing 210 may be an implementation of the wound dressing of Figure 1. The wound dressing 210 may include one or more dressing sensors 212 configured to generate sensor data in response to conditions detected at or near the wound. The one or more dressing sensors 212 may include an impedance or conductivity sensor (impedance or conductance measurements may be used, for example, to distinguish between living and dead tissue or to monitor healing progress), a temperature sensor (temperature measurements may be used, for example, to provide information about the wound environment or surrounding air), a light source or photodetector (spectral characteristics of tissue may be used, for example, to understand tissue health or healing trajectory), a pH sensor, a pressure sensor, a perfusion sensor, an accelerometer, a gyroscope, a magnetometer, etc. The wound dressing 210 may include one or more electronic components 214 that can facilitate the operation of one or more dressing sensors 212 (such as via control or power supply) or the communication of sensor or dressing data (such as a dressing type or an assigned dressing identifier for uniquely identifying the wound dressing 210 from multiple different wound dressings) to a monitoring device 220 or a display device 230, such as via radio waves or one or more electrical wires.

[0045] The wound dressing 210 or one or more other components of the wound monitoring system 200 may be configured as described in International Patent Application Publication No. WO2017195038 entitled "SENSOR ENABLED WOUND MONITORING AND THERAPY APPARATUS," International Patent Publication No. WO2018189265 entitled "COMPONENT STRESS RELIEF FOR SENSOR ENABLED NEGATIVE PRESSURE WOUND THERAPY DRESSINGS," International Patent Publication No. WO2019020551 entitled "SKEWING PADS FOR IMPEDANCE MEASUREMENT," and International Patent Publication No. WO2019020551 entitled "SENSOR POSITIONING AND OPTICAL SENSING FOR SENSOR ENABLED WOUND THERAPY DRESSINGS AND APPARATUS." The present invention may include or be used in conjunction with any of the features described in International Patent Publication No. WO2019063488, entitled "METHOD SYSTEMS," each of which is incorporated herein by reference in its entirety.

[0046] Although not shown, the wound dressing 210 may include a pressure source, such as a source of negative pressure, such that the wound dressing 210 itself may generate negative pressure to provide pressure therapy, such as the wound therapy device 150 of Figure 1. An exemplary implementation of a wound dressing with a pressure source is described in International Patent Application Publication No. WO2019193141, entitled "NEGATIVE PRESSURE WOUND TREATMENT APPARATUSES AND METHODS WITH INTEGRATED ELECTRONICS," the disclosure of which is incorporated herein by reference in its entirety.

[0047] The monitoring device 220 may include a monitoring controller 221, a monitoring memory device 222, a monitoring user interface 223, a monitoring power supply 224, one or more monitoring sensors 225, and a monitoring communication interface 226, which may be configured to communicate with each other electrically or otherwise. The monitoring power supply 224 may provide power to one or more components of the monitoring device 220 and may, for example, be connected to a mains power source or include a battery. One or more of the components of the monitoring device 220 may be contained within or supported by a monitoring device housing. The monitoring device 220 may be, for example, a hospital patient monitor that may communicate with one or more other devices in a care environment or via a computer network. Although not shown, the monitoring device 220 may include a pressure source, such as a source of negative pressure, so that the monitoring device 220 can function as a therapy device, such as the wound therapy device 150 of FIG. 1.

[0048] The monitoring controller 221 may control the operation of one or more other components of the monitoring device 220 (e.g., the monitoring memory device 222, the monitoring user interface 223, the monitoring power supply 224, one or more monitoring sensors 225, or the monitoring communication interface 226) according to instructions stored at least in the monitoring memory device 222. The monitoring controller 221 may collect sensor data from the wound dressing 210 via the monitoring communication interface 226, process the collected sensor data, generate one or more graphical representations (which may include one or more heat maps) from the collected or processed sensor data, store the collected or processed sensor data or the one or more graphical representations in the monitoring memory device 222, and transmit the collected or processed sensor data or the one or more graphical representations via the monitoring communication interface 226. The monitoring controller 221 may collect sensor data from the wound dressing 210, one or more monitoring sensors 225, or other sensors in the wound monitoring system 200, and determine from the collected sensor data the relative position of the wound dressing 210. The monitoring controller 221 may use the relative position to generate one or more movement instructions to guide manual placement of the wound dressing 210 on the wound, and transmit the one or more movement instructions via the monitoring communication interface 226.

[0049] The monitoring user interface 223 may include one or more output elements, such as a visual feedback device (e.g., a light-emitting diode or display screen), a tactile feedback device, or an auditory device (e.g., a speaker), that provide user output to a user, such as a healthcare professional. The one or more output elements may communicate status information to the user, such as whether the monitoring device 220 is functioning properly, collecting sensor data from the wound dressing 210, or communicating with the wound dressing 210 or the display device 230. The monitoring user interface 223 may include one or more input elements, such as buttons, switches, dials, touchpads, microphones, or touch screens, for configuring the wound dressing 210, the monitoring device 220, or the display device 230.

[0050] The one or more monitoring sensors 225 may include one or more accelerometers, gyroscopes, magnetometers, impedance sensors, thermistors, pressure sensors, or optical sensors, among other types of sensors. The one or more monitoring sensors 225 may be supported by the monitoring device housing or may be usable to monitor the monitoring device 220 or one or more components or characteristics of an individual near the monitoring device 220, but remote from the housing of the monitoring device 220.

[0051] One or more monitoring sensors 225 may be used to detect and monitor the position or movement of the wound dressing 210, the monitoring device 220, or the display device 230, as well as one or more nearby items or individuals (such as a patient or medical personnel). One or more monitoring sensors 225 may additionally or alternatively be used to detect and monitor other conditions at or near the monitoring device 220. The conditions at or near the monitoring device 220 may indicate one or more conditions at or near the wound covered by the wound dressing 210, such as ambient conditions around the wound. The one or more monitoring sensors 225 may output sensor data that can be used to determine, for example, how to guide movement of the wound dressing 210 for placement on the wound or how to position one or more graphical representations for viewing by a user.

[0052] The monitoring communication interface 226 can be used to communicate with other devices, such as via radio wave or wired communication. (商標)The monitoring communication interface 226 may be implemented according to a communications protocol, such as a protocol. The monitoring communication interface 226 may communicate with other devices to send and receive device usage or sensor data (e.g., among other possibilities: [i] sensor data generated by one or more dressing sensors 212 before or after processing by the monitoring controller 221; [ii] sensor data indicative of the location or movement of the wound dressing 210, the monitoring device 220, or the display device 230, and one or more nearby items or individuals; [iii] one or more movement instructions for moving the wound dressing 210 for placement; [iv] one or more graphical representations based at least on the sensor data generated by the one or more dressing sensors 212 before or after processing by the monitoring controller 221; [v] alarms; or [vi] changes to a monitoring or therapy program implemented by the monitoring device 220), as well as commands (such as an activation command to activate one or more dressing sensors 212 or a request command to have the wound dressing 210 provide sensor data). The monitoring communication interface 226 may, in some embodiments, be unable to communicate with the wound dressing 210 or display device 230 over a distance of more than 10 meters, 30 meters, or 100 meters.

[0053] The display device 230 may include a display controller 231, a display memory device 232, a display user interface 233, a display power supply 234, one or more display sensors 235, and a display communication interface 236, which may be configured to electrically communicate with each other. The display power supply 234 may provide power to one or more components of the display device 230 and may, for example, be connected to a mains power source or include a battery. One or more of the components of the display device 230 may be housed within or supported by a display device housing. The display device housing may be head-mountable, such that the display device 230 may be a head-mounted display (HMD). Alternatively, the display device housing may not be head-mountable, and the display device 230 may be, for example, a mobile device or a smart TV, or may operate to project images via form projection technology, for example.

[0054] Display controller 231 may control the operation of one or more other components of display device 230 (e.g., display memory device 232, display user interface 233, display power supply 234, one or more display sensors 235, or display communication interface 236) according to instructions stored at least in display memory device 232. Display controller 231 can receive one or more movement instructions from monitoring device 220 via display communication interface 236 and output the one or more movement instructions to display user interface 233 to guide movement of wound dressing 210 and for presentation to a user. Display controller 231 can receive one or more graphical representations from monitoring device 220 via display communication interface 236, determine from sensor data from wound dressing 210 or collected or processed sensor data from monitoring device 220 how to position the one or more graphical representations on display user interface 233, and output the one or more graphical representations to display user interface 233 for presentation to a user. Additionally or alternatively, the display controller 231 itself may determine one or more movement instructions or graphical representations from sensor data from the wound dressing 210 or collected or processed sensor data from the monitoring device 220.

[0055] The display user interface 233 may include one or more output elements, such as a visual feedback device (e.g., one or more display screens or light-emitting diodes), a tactile feedback device, or an auditory device (e.g., a speaker), that provide user output to the user. The one or more output elements may communicate to the user (visually, via augmented reality, etc.) one or more movement instructions, as well as status information, such as whether the display device 230 is functioning normally, collecting sensor data from the wound dressing 210, or collecting or processed sensor data from the monitoring device 220, or communicating with the wound dressing 210 or the monitoring device 220. The display user interface 233 may include one or more input elements, such as buttons, switches, dials, a touchpad, a microphone, or a touch screen, for receiving user input for configuring the display device 230.

[0056] The one or more display sensors 235 may include one or more accelerometers, gyroscopes, magnetometers, impedance sensors, thermistors, pressure sensors, or optical sensors, among other types of sensors. The one or more display sensors 235 may be supported by the display device housing or may be usable to monitor the display device 230 or one or more components or characteristics of an individual near the display device 230, but remote from the display device housing.

[0057] One or more display sensors 235 may be used to detect and monitor the position or movement of the wound dressing 210, the monitoring device 220, or the display device 230, as well as one or more nearby items or individuals (such as a patient or medical personnel). One or more display sensors 235 may additionally or alternatively be used to detect and monitor conditions at or near the display device 230. The conditions at or near the display device 230 may indicate one or more conditions at or near the wound covered by the wound dressing 210, such as ambient conditions around the wound. The one or more display sensors 235 may output sensor data that can be used to determine, for example, how to guide movement of the wound dressing 210 for placement on the wound or how to position one or more graphical representations on the display user interface 233.

[0058] The display communication interface 236 can be used to communicate with other devices, such as via radio wave or wired communication. Communication via radio waves is exemplified by Bluetooth. (商標)The communication may be performed according to a communication protocol, such as a protocol. The display communication interface 236 can, for example, communicate with other devices and transmit device usage or sensor data (e.g., among other possibilities: [i] sensor data generated by one or more dressing sensors 212 before or after processing by the monitoring controller 221 or the display controller 231; [ii] sensor data indicative of the location or movement of the wound dressing 210, the monitoring device 220, or the display device 230, and one or more nearby items or individuals; [iii] one or more movement instructions for moving the wound dressing 210 for placement; [iv] one or more graphical representations based at least on the sensor data generated by one or more dressing sensors 212 before or after processing by the monitoring controller 221; [v] one or more indications of how to position the one or more graphical representations on the display user interface 233; [vi] alarms; or [vii] changes to a monitoring or therapy program implemented by the monitoring device 220 or the display device 230), as well as commands (such as an activation command to activate one or more dressing sensors 212 or a request command to have the wound dressing 210 provide sensor data). The display and communication interface 236 may, in some embodiments, be unable to communicate with the wound dressing 210 or monitoring device 220 over a distance of more than 10 meters, 30 meters, or 100 meters.

[0059] 3 illustrates a positioning guidance process 300. For convenience, the positioning guidance process 300 is described as being performed by the display device 230 and in the context of the wound monitoring system 200, but may instead be implemented by other components or systems described herein or not shown. The positioning guidance process 300 can advantageously, in certain aspects, assist a healthcare professional by providing augmented reality dressing placement guidance in the context of the wound area so that the healthcare professional can be aided in accurately placing a wound dressing on the wound. Because the dressing placement guidance may be in the context of the wound area or even fixed in proximity to the wound, the dressing placement guidance may be easy to understand and follow.

[0060] At block 310, the positioning guidance process 300 may determine the relative position of the wound dressing. For example, the display controller 231 may determine the relative position of the wound dressing 210 with respect to the wound, or a location on the patient where another wound dressing was previously placed. The relative position may be a vector that can identify the x-axis location, y-axis location, and z-axis location of the wound dressing 210, as well as a magnitude indicating the distance and direction from the wound dressing 210 to a location, such as a point near the wound or a location on the patient where another dressing was previously placed. The relative position may be determined from sensor data (such as data from an accelerometer, gyroscope, magnetometer, or optical sensor) generated by one or more dressing sensors 212, one or more monitoring sensors 225, or one or more display sensors 235.

[0061] At block 320, the positioning guidance process 300 may determine whether the wound dressing 210 is correctly positioned. For example, the display controller 231 may determine whether the wound dressing 210 can be correctly positioned by determining whether the wound dressing 210 is desirably positioned and oriented on the patient so that the wound dressing 210 may be used to treat the wound. The display controller 231 may determine or store the desired location and orientation of the wound dressing 210 on the patient, as well as an allowable tolerance for the desired location and orientation. The wound dressing 210 may be correctly positioned when the display controller 231 determines that the wound dressing 210 is located on the patient within an allowable tolerance from the desired location and orientation. The wound dressing 210 may be incorrectly positioned when the display controller 231 determines that the wound dressing 210 is not located on the patient within an allowable tolerance from the desired location and orientation.

[0062] If the positioning guidance process 300 determines that the wound dressing is improperly positioned, the positioning guidance process 300 can proceed to block 330 and generate movement instructions from the relative position. For example, the display controller 231 can use the relative position to generate movement instructions that can be used to guide manual placement by a user, such as a healthcare professional, of the wound dressing 210 on the wound. The movement instructions may indicate a direction to move the wound dressing and a distance to move the wound dressing. For example, the movement instructions may indicate to shift or rotate the wound dressing by a particular amount or degree.

[0063] At block 340, the positioning guidance process 300 can present movement instructions to the user via augmented reality. For example, the display user interface 233 can present the movement instructions in augmented reality on a display, such as a head-mounted display, a mobile device screen, or via morphological projection technology, so that the movement instructions can be overlaid on an area near the patient from the user's perspective. The movement instructions can be presented with the movement instructions positioned above the wound (or another location on or above the patient) and appearing fixed above (or another location) the wound from a visual perspective, so that the location of the movement instructions appears fixed relative to the patient as the user moves around the patient. In some implementations, the display controller 231 may determine a marking location (e.g., one or more skin spots, one or more wound perimeter features, the shape of the wound, the shape of the wound dressing, the position of the wound dressing, or one or more markings on the wound dressing) of a marking on or proximal to the wound or patient, and the display user interface 233 can present the movement instructions at or a set distance from the marking location from a visual perspective.

[0064] Following block 340, the positioning guidance process 300 may return to block 310 to determine the relative position of the wound dressing, where the relative position may be different because the user may have manually moved the wound dressing 210.

[0065] If, at block 320, the positioning guidance process 300 determines that the wound dressing is now correctly positioned, the positioning guidance process 300 may proceed to block 350 and generate a placement confirmation. For example, the display device controller 231 may generate a placement confirmation that may indicate that the wound dressing 210 may be correctly placed and oriented on the patient.

[0066] At block 360, the positioning guidance process 300 may present movement instructions to the user. For example, the display user interface 233 may present the user with an augmented reality positioning confirmation on the display such that the positioning instructions may be overlaid on an area near the patient from the user's perspective. The positioning instructions may be presented with the positioning instructions positioned above the wound (or another location on or above the patient) and appearing fixed above the wound (or another location) from a visual perspective, so that the location of the positioning instructions appears fixed relative to the patient as the user moves around the patient.

[0067] The positioning guidance process 300, in certain implementations, may further include adjusting sensor data collected by the wound dressing. For example, the monitoring controller 221 or the display controller 231 may determine that the wound dressing 210 may be placed in a different location relative to a previous placement of another wound dressing. Rather than indicating that the different location may be inaccurate, the monitoring controller 221 or the display controller 231 may determine to adjust the sensor data collected by one or more dressing sensors 212 and adjust accordingly (e.g., spatially shift or change orientation) to compensate for the placement at the different location.

[0068] Although the positioning guidance process 300 may be described in the context of positioning a wound dressing, the positioning guidance process 300 may further be applied to assisting in the placement of other devices on an individual, such as a person or an animal. For example, the positioning guidance process 300 may be used for the placement of an activity monitoring device, such as those described in International Patent Application Publication No. WO2019162272, entitled "MONITORING OF BODY LOADING AND BODY POSITION FOR THE TREATMENT OF PRESSURE ULCERS OR OTHER INJURIES," International Patent Application Publication No. WO2019234011, entitled "DEVICE COMMUNICATION MANAGEMENT IN USER ACTIVITY MONITORING SYSTEMS," and International Patent Application Publication No. WO2019238927, entitled "DEVICE HOUSING AND MOUNTING IN USER ACTIVITY MONITORING SYSTEMS," the disclosures of which are incorporated by reference in their entireties.

[0069] 4A shows wound treatment system 400 prior to activation of movement instructions to assist in placement of wound dressing 420, such as prior to activation of an overlay on display user interface 233 of display device 230 of FIG. 2. Wound treatment system 400 may be shown from the perspective of a user, such as a healthcare professional. Additionally, wound treatment system 400 may be viewable by the user through a display, such as a head-mounted display.

[0070] Wound treatment system 400 may include a patient's limb 410 having a wound 412 thereon. Wound treatment system 400 may further include a user's left hand 430 and right hand 432 holding a wound dressing 420, which may be an implementation of wound dressing 210 of Figure 2. Wound dressing 420 may have an identification marker 422 on its outer surface, which may be used to detect the orientation of wound dressing 420.

[0071] Figure 4B shows wound treatment system 400 after activation of a movement command, such as after activation of an overlay on display user interface 233. Positioning guidance process 300 at blocks 310, 320, 330, and 340 may be performed to arrive at wound treatment system 400 shown in Figure 4B.

[0072] 4B, the user may now be presented with movement instructions including a downward arrow 440, a clockwise orientation arrow 442, and a right shift arrow 444. The downward arrow 440, the clockwise orientation arrow 442, and the right shift arrow 444 may be displayed to the user to move the wound dressing 420 downward, rotate the wound dressing 420 clockwise, and move the wound dressing to the right, respectively. The size, color, or one or more other characteristics of the downward arrow 440, the clockwise orientation arrow 442, and the right shift arrow 444 may be used to indicate the distance, degree, or amount the user is instructed to move the wound dressing 420. Additionally, a placement outline 446 and a placement marker 448 may be displayed to indicate to the user the desired location and orientation of the wound dressing 420. The user can achieve correct placement of the wound dressing 420 on the limb 410 by aligning the placement outline 446 with the perimeter of the wound dressing 420 and aligning the identification marker 422 with the placement marker 448.

[0073] Figure 4C illustrates the wound treatment system 400 when the wound dressing 420 may be positioned on the limb 410, but is not within an acceptable tolerance from the desired location and orientation. The positioning guidance process 300 at blocks 310, 320, 330, and 340 may be performed to arrive at the wound treatment system 400 shown in Figure 4C. As can be seen in Figure 4C, an incorrect placement 450 may be presented to the user to indicate that the user should not leave the wound dressing 420 positioned in its current location.

[0074] Figure 4D shows the wound treatment system 400 when the wound dressing 420 may be positioned on the limb 410 at the desired location, but in an incorrect orientation. The positioning guidance process 300 at blocks 310, 320, 330, and 340 may be performed to arrive at the wound treatment system 400 shown in Figure 4D. As can be seen in Figure 4D, an incorrect orientation 460 may be presented to the user to indicate that the user should not leave the wound dressing 420 positioned in its current orientation.

[0075] Figure 4E shows the wound treatment system 400 as it may be positioned on the limb 410 with the wound dressing 420 in a desired location and orientation. The positioning guidance process 300 at blocks 310, 320, 350, and 360 may be performed to arrive at the wound treatment system 400 shown in Figure 4E. As can be seen in Figure 4E, the correct placement and orientation 470 may be presented to the user to indicate that the user should not leave the wound dressing 420 positioned in its current orientation.

[0076] In certain implementations, the identification marker 422 may be usable to uniquely identify the wound dressing 420 from a plurality of different wound dressings. In such implementations, the identification marker 422 may be an optical, machine-readable representation of a unique identifier for the wound dressing 420, rather than an X. For example, the identification marker 422 may be used by the monitoring device 220 or the display device 230 to uniquely identify the wound dressing 420 from a set of different wound dressings. The monitoring device 220 or display device 230 may then use the identification information determined from the identification marker 422 to automatically customize [i] a configuration or setting for communicating with or using the wound dressing 420, [ii] how sensor data from the wound dressing 420 is collected, processed, or associated with a patient record in a database, or [iii] how the information is presented to the user in augmented reality (e.g., the identification information may be used to assign default display settings for the wound dressing 420, such as color, size, or which sensor data to assign to which layer of a graphical representation generated for the wound dressing 420).

[0077] 5 illustrates a graphical representation generation and presentation process 500. For convenience, the graphical representation generation and presentation process 500 is described as being performed by the monitoring device 220 and the display device 230 and in the context of the wound monitoring system 200, but may instead be implemented by other components or systems described herein or not shown. The graphical representation generation and presentation process 500 can advantageously, in certain aspects, assist a medical professional by providing sensor-derived information for a wound in augmented reality in the context of the wound area so that the medical professional can better understand the condition of the wound without removing a wound dressing. The provided sensor-derived information can be easy to understand and follow because it may be within the context of the wound area or even fixed in proximity to the wound where the corresponding sensor data was detected.

[0078] At block 510, the graphical representation generation and presentation process 500 may receive sensor data from sensors monitoring a wound covered by a wound dressing. For example, the monitoring device 220 may receive the sensor data from the wound dressing 210 via the monitoring communication interface 226. The sensor data may be collected by one or more dressing sensors 212, which may monitor a wound covered by the wound dressing 210 or an adjacent area. The sensor data may include impedance or conductivity data, temperature data, optical data, pH data, pressure data, perfusion data, accelerometer data, gyroscopic data, or magnetometer data, among others, for the wound or an adjacent area.

[0079] At block 520, the graphical representation generation and presentation process 500 may generate a graphical representation from the sensor data. For example, the monitoring device 220 may generate a graphical representation from the sensor data received from the wound dressing 210. The graphical representation may be or include one or more visual representations of the variation in one or more characteristics at the wound or adjacent areas, such as how the one or more characteristics vary spatially across the wound or adjacent areas. The graphical representation may include color coding of the values ​​of the sensor data before or after processing by the monitoring controller 221. The graphical representation may have a first side and a second side opposite the first side, where the first side of the graphical representation may represent sensor data detected on the first side of the wound dressing 210 and the second side of the graphical representation may represent sensor data detected on the second side of the wound dressing 210 opposite the first side of the wound dressing 210.

[0080] The graphical representation may include multiple layers, such as one, two, three, four, or more layers, which may be generated for presentation separate from one another (e.g., one layer spatially above another). Each of the multiple layers may show different information, which may be determined from a different type of sensor in the one or more dressing sensors 212. One of the multiple layers may represent one of impedance or conductivity variations, temperature variations, optical variations, pH variations, pressure variations, perfusion variations, or movement variations, among others, in the wound or adjacent area, and another of the multiple layers may represent a different one of the variations in the wound or adjacent area.

[0081] After generating the graphical representation, the monitoring device 220 may transmit the graphical representation to the display device 230 via the monitoring communication interface 226 .

[0082] At block 530, the graphical representation generation and presentation process 500 can present the graphical representation to a user via augmented reality. For example, the display device 230 can present the graphical representation on a display of a display user interface 233, such as a head-mounted display, a screen of a mobile device, or via form projection technology, so that the graphical representation can be overlaid on an area near the patient from the visual perspective of a user, such as a healthcare professional. The graphical representation can be presented in real time by receiving sensor data at block 510, generating the graphical representation at block 520, or generating sensor data by one or more dressing sensors 212.

[0083] The graphical representation may be presented with the graphical representation positioned above the wound (or another location on or above the patient) and appearing fixed above (or another location on) the wound from a visual standpoint, such that the location of the graphical representation appears fixed relative to the patient as the user moves around the patient. Display controller 231 may, in some implementations, determine a marking location (e.g., one or more skin spots, one or more wound perimeter features, wound shape, wound dressing shape, wound dressing location, or one or more markings on a wound dressing) of markings on or proximal to the wound or patient, and display user interface 233 may present the graphical representation at or a set distance from the marking location from a visual standpoint.

[0084] Where the graphical representation may have a first side and a second side opposite the first side, and the wound dressing 210 may have a first side and a second side opposite the first side, the graphical representation may be presented such that, from a visual standpoint, the first side of the graphical representation (which may represent sensor data detected on the first side of the wound dressing 210 before or after processing by the monitoring controller 221) may be positioned in proximity to, for example, overlaid on or above, the first side of the wound dressing 210, and the second side of the graphical representation (which may represent sensor data detected on the second side of the wound dressing 210 before or after processing by the monitoring controller 221) may be positioned in proximity to, for example, overlaid on or above, the second side of the graphical representation

[0085] Where the graphical representation may include multiple layers, the graphical representation may be presented such that one or more of the multiple layers may be presented separately from one or more other layers of the multiple layers, e.g., one of the multiple layers may appear from a visual standpoint to be separate from and positioned above another layer of the multiple layers.

[0086] Upon completion of graphical representation generation and presentation process 500, display user interface 233 may present one or more media interface elements that may enable a user to provide one or more user inputs to control the generation or presentation of the graphical representation. Display user interface 233 may, for example, adjust the presentation of the graphical representation (e.g., by presenting different types of sensor data or different timing of sensor data, at shifting locations where the graphical representation, or different portions of the graphical representation, may be displayed) in response to user input to display user interface 233.

[0087] Although the graphical representation generation and presentation process 500 may be described using the example of the monitoring device 220 and the display device 230 sharing processing responsibilities, the graphical representation generation and presentation process 500 may be performed entirely by the display device 230 in certain implementations.

[0088] The graphical representation generation and presentation process 500 may not affect the performance of negative pressure wound therapy using a wound dressing such as the wound dressing 210. The wound dressing may continue to cover and seal the wound and maintain negative pressure around the wound while the graphical representation generation and presentation process 500 is performed.

[0089] Figure 6A shows the wound treatment system 400 of Figures 4A-4E when the wound dressing 420 has been placed in a desired location and orientation. Figure 6A may show the wound treatment system 400 after the appearance of the wound treatment system 400, for example, as illustrated in Figure 4E.

[0090] As shown in FIG. 6A, the wound treatment system 400 may include an activation overlay element 602, which may be selectable by a user. The activation overlay element 602 may be presented to the user by the display user interface 233 in augmented reality as shown, and the selection of the activation overlay element 602 by the user may be detected. The selection may be detected, for example, using an optical sensor of one or more display sensors 235 that detects a gesture by the user toward the activation overlay element 602. The selection of the activation overlay element 602 may initiate the presentation of a graphical representation as described in block 530 of the graphical representation generation and presentation process 500, triggering the wound treatment system 400 as shown in FIG. 6B.

[0091] 6B shows the wound treatment system 400 when a graphical representation is presented in augmented reality by a display user interface 233 that includes multiple layers, including a first layer 610, a second layer 612, a third layer 614, and a fourth layer 616. Each of the multiple layers can present different information, which can be determined, for example, from a different type of sensor in the one or more dressing sensors 212 monitoring the wound 412. In one example, the first layer 610 may indicate impedance or conductivity variations underneath the wound dressing 420, the second layer 612 may indicate temperature variations underneath the wound dressing 420, the third layer 614 may indicate optical variations underneath the wound dressing 420, and the fourth layer 616 may indicate pH variations underneath the wound dressing 420.

[0092] The presentation of information by the multiple layers at points on each of the multiple layers may spatially correspond to characteristics detected underneath the wound dressing 420 at points that, from a user's visual perspective, appear directly underneath the multiple layers, as shown in Figure 6C. As a result, features of the wound 412, such as the outline of the wound 412, may be visible on each of the multiple layers as shown in Figure 6C.

[0093] The deactivation overlay element 604 and more information elements 620 may be presented on the wound treatment system 400 as shown in FIG. 6B. The deactivation overlay element 604 and more information elements 620 may be presented in augmented reality by the display user interface 233, which may detect a user's selection of the deactivation overlay element 604 or more information elements 620, such as using an optical sensor of one or more display sensors 235 to detect a user gesture toward the deactivation overlay element 604 or more information elements 620. Selection of the deactivation overlay element 604 deactivates the presentation of the graphical representation and triggers the wound treatment system 400, as shown in FIG. 6A. Selection of the more information elements 620 may initiate the presentation of one or more media interface elements and trigger the wound treatment system 400, as shown in FIG. 6D.

[0094] 6D illustrates the wound treatment system 400 when one or more media interface elements are presented in augmented reality by the display user interface 233. The one or more media interface elements may include a play / pause element 630, a fast forward element 632, a jump forward element 634, a jump back element 636, a fast back element 638, a first tier switch element 640, a second tier switch element 642, and a third tier switch element 624. The display user interface 233 can detect selection of one or more media interface elements or one of the multiple layers, such as using an optical sensor of the one or more display sensors 235 that detects a gesture by a user toward the one or more media interface elements or one of the multiple layers.

[0095] The play / pause element 630, fast forward element 632, jump forward element 634, jump back element 636, and fast back element 638 may be selected by a user to control the presentation of information through one or more of the multiple layers. Selection of the play / pause element 630 may cause one or more of the multiple layers to play or pause playback of information from one or more of the multiple layers. Selection of the fast forward element 632 may cause one or more of the multiple layers to initiate fast playback (e.g., at 1.5x, 2x, 3x, 5x, 10x, 25x, or 50x speed) of information from one or more of the multiple layers. Selection of the jump forward element 634 may cause one or more of the multiple layers to skip forward a set amount of time (e.g., 10 seconds, 30 seconds, 1 minute, 5 minutes, 15 minutes, 30 minutes, or 1 hour) in playback of information from one or more of the multiple layers. Selection of the jump back element 636 may cause one or more of the layers to skip back a set amount of time (e.g., 10 seconds, 30 seconds, 1 minute, 5 minutes, 15 minutes, 30 minutes, or 1 hour) in playback of information on one or more of the layers. Selection of the fast back element 638 may cause one or more of the layers to initiate fast playback (e.g., at x1.5, x2, x3, x5, x10, x25, or x50 speed) in playback of information on one or more of the layers.

[0096] The play / pause element 630, fast forward element 632, jump forward element 634, jump return element 636, and fast return element 638 may be operated in one or more of a number of tiers that may be selected by the user prior to selection of the play / pause element 630, fast forward element 632, jump forward element 634, jump return element 636, or fast return element 638. The play / pause element 630, fast forward element 632, jump forward element 634, jump return element 636, and fast return element 638 may thus assist the user in efficiently reviewing and understanding characteristics of the wound 412 and its adjacent areas over time (e.g., over seconds, minutes, hours, or days).

[0097] 6D , a timestamp may be presented in augmented reality with multiple layers. A first layer 610 may be presented with a timestamp of “January 18, 2020, 8:30 AM,” which may indicate information presented by the first layer 610 that may correspond to sensor data collected at the wound dressing 420 on January 18, 2020, at 8:30 AM. A second layer 612 may be presented with a timestamp of “January 18, 2020, 8:30 AM,” which may indicate information presented by the second layer 612 that may correspond to sensor data collected at the wound dressing 420 on January 18, 2020, at 8:30 AM. The first layer 610 and the second layer 612 may present sensor data collected at the wound dressing 420 at a common time. The third layer 614 may be presented with a timestamp of "January 18, 2020, 8:00 AM," which may indicate information presented by the third layer 614, which may correspond to sensor data collected at the wound dressing 420 at 8:00 AM on January 18, 2020. The fourth layer 616 may be presented with a timestamp of "January 18, 2020, 7:00 AM," which may indicate information presented by the fourth layer 616, which may correspond to sensor data collected at the wound dressing 420 at 7:00 AM on January 18, 2020. The third layer 614 and the fourth layer 616 may present sensor data collected at the wound dressing 420 at different times, and at times different from the common time of the first layer 610 and the second layer 612.

[0098] The first layer switch element 640, the second layer switch element 642, and the third layer switch element 624 may be selected by a user to switch the position of one or more of the layers. Selection of the first layer switch element 640 may cause the first layer 610 and the second layer 612 to switch positions from the user's perspective. Selection of the second layer switch element 642 may cause the second layer 612 and the third layer 614 to switch positions from the user's perspective. Selection of the third layer switch element 644 may cause the third layer 614 and the fourth layer 616 to switch positions from the user's perspective.

[0099] As shown in Figure 6D, fewer information elements 650 can be presented to wound treatment system 400. More information elements 650 can be presented in augmented reality by display user interface 233, which can detect a user selection of fewer information elements 650, such as using an optical sensor of one or more display sensors 235 to detect a gesture by the user toward fewer information elements 650. Selection of fewer information elements 650 can remove one or more media interface elements from presentation and can trigger wound treatment system 400, as shown in Figure 6B.
