Description
A DEVICE FOR PROVIDING LIGHT THERAPY TO A WOUNDFIELD OF INVENTION
[0001] The present disclosure relates to medical devices for wound treatment, and more particularly to a wound healing device incorporating therapeutic delivery capabilities with embedded therapeutic tubes and a detachable controller having a connection interface for delivering targeted therapy to a wound site.BACKGROUND
[0002] Wounds are categorized into different types based on factors such as the source of the wound and the underlying tissue that may be affected. A closed wound does not break the surface of the skin but causes damage to the underlying tissues. An open wound breaks the skin's surface and may damage the underlying tissues. Proper wound care and timely treatment are important for promoting healing and preventing complications such as infection.
[0003] In deep wounds, a doctor may close a wound using staples, stitches, glues, or other forms of wound-closing procedures to reduce tissue loss and allow the body to focus on closing and healing a smaller wound area than the initial large wound. The wound closure process may aim to enable rapid skin healing, prevent infection, and achieve a good cosmetic result. Effective wound closure may also reduce patient discomfort and facilitate early mobilization.
[0004] In traditional methods, a doctor may use sutures to perform stitching of the wound, which may leave a scar after the healing process is complete. With advancements in medical technology, sutures may be replaced by skin staples, tissue adhesives, and surgical tapes. After removal, staples may cause infections, bleeding, additional dressing requirements, or scar formation at piercing sites. These complications may prolong the overall healing time and may require additional medical intervention.
[0005] Adhesive tapes may bind on either side of the wound and may be tightened by a pull mechanism to seal the wound. Adhesive tapes may be designed to replace staples and sutures for closure of the superficial skin layer. Adhesive tapes may be applied directly to intact skin on either side of an incision, providing uniform force along the wound edge. However, conventional adhesive tapes may not provide therapeutic benefits beyond mechanical wound closure.
[0006] Some existing wound closure devices incorporate fastening mechanisms such asrestraint zones or bands arranged between base bands on either side of a wound, with locking devices to secure the bands in place. Other wound closure devices use strap arrangements with buckles or connectors to hold the straps in tension and draw wound edges together. These devices focus primarily on mechanical wound closure and may include features such as tension indicators or quick-release mechanisms. However, such devices do not incorporate light therapy capabilities for promoting wound healing.
[0007] Some wound treatment devices incorporate therapeutic elements such as sensors and therapy delivery components. For example, some devices include sensory or therapeutic elements disposed within wound closure panels, where the therapeutic elements may comprise light sources for phototherapy, heating elements, or drug delivery elements. Other devices include multifunctional wound dressings with electrical, optical, or mechanical stimulation means for transmitting energy towards a wound.
[0008] Furthermore, conventional wound-treatment devices with therapeutic capabilities are typically designed for single use and are discarded after each treatment session. As a result, complete electronic circuitry, including controllers, power sources, and stimulation elements, is disposed of together with the used dressing, leading to significant wastage of electronic components and increased electronic waste. Because each disposable device must contain a full set of electronic hardware, the cost per treatment becomes high and limits widespread adoption, particularly in resource-constrained settings.
[0009] In contrast, a configuration employing a detachable and reusable controller would require the disposable bandage or patch component to contain only the stimulation element or passive therapeutic interface. The same controller could be removably coupled to successive bandage devices after the earlier patch is discarded, thereby substantially reducing material wastage, lowering per-treatment cost, and enabling more sustainable use of therapeutic woundclosure systems.
[0010] Although therapeutic modalities such as phototherapy, electrical stimulation, heat or cooling therapy, mechanical vibration, ultrasound therapy, and drug delivery have been shown to promote wound healing, existing adhesive-strip-based closure devices do not incorporate embedded therapeutic tubes or interfaces for delivering targeted therapy along the wound edges. Moreover, currently available systems with therapeutic capability fail to provide a detachable and reusable controller with a flexible connection interface that can operate with one or more stimulation elements and with multiple disposable patch components. Therefore,there remains a need for improved systems and methods that combine reliable wound-closure functionality with integrated therapeutic delivery and a reusable controller architecture to address at least one or more of the foregoing shortcomings in the art.OBJECTIVES OF THE INVENTION

[0052] In addition to conventional mineral-based LEDs, one or more LEDs may also be provided on an Organic LED (OLED) based flexible panel or an inorganic LED-based flexible panel. Such OLED panels may be generated by depositing organic semiconducting materials over Thin Film Transistor (TFT) based substrates. Further, a discussion on the generation of OLED panels can be found in Bardsley, J. N (2004), “International OLED Technology Roadmap”, IEEE Journal of Selected Topics in Quantum Electronics, Vol. 10, No. 1, that is included herein in its entirety, by reference. An exemplary description of flexible inorganic light-emitting diode strips can be found in granted U.S. Pat. No. 7,476,557 B2, titled “Roll-to-roll fabricated light sheet and encapsulated semiconductor circuit devices”, which is included herein in its entirety by reference.
[0053] In the context of this specification, terms like “light”, “radiation”, “irradiation”, “emission” and “illumination”, etc. refer to electromagnetic radiation in frequency ranges varying from the Ultraviolet (UV) frequencies to Infrared (IR) frequencies and wavelengths, wherein the range is inclusive of visible light, UV and IR frequencies and wavelengths. It is to be noted here that UV radiation can be categorized in several ways depending on respective wavelength ranges, all of which are envisaged to be under the scope of this invention. For example, UV radiation can be categorized as Hydrogen Lyman-a (122-121 nm), Far UV (200-122 nm), Middle UV (300-200 nm), and Near UV (400-300 nm). The UV radiation may also be categorized as UVA (400-315 nm), UVB (315-280 nm), and UVC (280-100 nm). Similarly, IR radiation may also be categorized into several categories according to respective wavelength ranges, which are again envisaged to be within the scope of this invention. A commonly used subdivision scheme for IR radiation includes Near IR (0.75-1.4 pm), Short-Wavelength IR (1.4-3 pm), Mid- Wavelength IR (3-8 pm), Long- Wavelength IR (8-15 pm), and Far IR (15-1000 pm).

In certain embodiments, the wound healing device is adapted for use in clinical settings or for home use by patients. The wound healing device provides an alternative or supplement to conventional wound closure methods such as sutures, staples, and adhesive tapes.
[0074] The wound healing device is configured to be designed in various forms suitable for different wound treatment applications. In an embodiment, the wound healing device may be designed in the form of a zipper bandage, a tissue adhesive, a surgical tape, or in the form of a device that can be attached to a wound using a different method.
[0075] The wound healing device is designed in various forms suitable for different wound treatment applications. In an embodiment, the wound healing device may be designed in the form of a zipper bandage, a tissue adhesive, a surgical tape, or in the form of a device that can be attached to a wound using a different method.
[0076] The first adhesive patch and the second adhesive patch may be formed from flexible biocompatible materials and may include adhesive layers for attachment to the skin. The patches may be interconnected through fastening members, bridging elements, or adjustable connectors to enable controlled approximation of the wound edges.
[0077] At least one of the first adhesive patch and the second adhesive patch comprises a therapeutic tube positioned along a respective edge adjacent to the wound site. In some embodiments, each of the first adhesive patch and the second adhesive patch includes a respective therapeutic tube so that therapeutic stimulation can be delivered along both sides of the wound.
[0078] The therapeutic tube on each patch forms a housing integrated with the disposable light therapy patch and configured to contain a medium or component for providing physical therapy, including phototherapy, microcurrent therapy, heating therapy, cooling therapy, vibration therapy, ultrasound therapy, or combinations thereof. The therapeutic tubes on the first adhesive patch and the second adhesive patch may be identical or may be configured fordifferent therapy modalities on the two sides of the wound.
[0079] In some embodiments, a single therapeutic tube may extend across both the first adhesive patch and the second adhesive patch, while in other embodiments, separate tubes may be provided on each patch portion. The position and length of the therapeutic tube are selected such that therapeutic energy is delivered substantially along the wound edges.
[0080] In an embodiment, each therapeutic tube is formed from a flexible biocompatible polymer material selected from medical-grade silicone, thermoplastic polyurethane, polyethylene, or similar elastomeric compositions. The therapeutic tube may be configured as a single-lumen structure or as a multi-lumen structure having separate internal passages for a medicinal fluid channel and for one or more components associated with physical therapy modalities. At least a portion of the wall of the therapeutic tube may be optically transmissive to permit emission of electromagnetic radiation toward the wound site. The therapeutic tube is bonded or integrated with the respective adhesive patch through adhesive lamination, thermal welding, co-extrusion, or over-molding so that the tube remains securely positioned along the edge of the adhesive patch during use.
[0081] In an embodiment, the wound healing device is implemented in a modular configuration in which the detachable controller is removably coupled to the light therapy patch comprising the first adhesive patch, the second adhesive patch, and the therapeutic tube.
[0082] In an embodiment, the detachable controller comprises active electronic components including power sources, control circuitry, driving circuits, and one or more stimulation elements, such as LEDs, ultrasound transducers, a heating element, a cooling element, and a vibration actuator. The one or more stimulation elements are configured to provide one or more physical therapies. In this configuration, the therapeutic tube on the first and / or second adhesive patch houses passive delivery members such as electrodes or conductive tracks, while the active stimulation source is located within the detachable controller.
[0083] As used herein, the term "passive delivery member" refers to an element housed within the therapeutic tube that passively delivers therapy generated by the stimulation element in the detachable controller to the wound site. The passive delivery member includes, but is not limited to, a light diffuser fiber for transmitting light, a metal wire or electrode for conducting electrical current, a heat conductive element for transferring heat, a cooling channel for transferring cooling, a medicinal delivery channel for transporting medicinal fluid, or a vibration transmission element for transmitting mechanical vibrations. The passive deliverymember is configured to receive energy, signals, or fluid from the stimulation element in the detachable controller through the connection interface and deliver the therapy uniformly along the length of the wound.
[0084] The passive delivery member is designed to provide uniform distribution of therapy along the entire length of the therapeutic tube without any gradient. The passive delivery member ensures that the same amount of therapy, whether heat, cooling, light, electrical stimulation, or other therapy, is delivered at each point along the length of the wound. For phototherapy, the light diffuser fiber is configured with uniform light scattering properties along its length to emit consistent light intensity at every point. For heat therapy, the heat conductive element is designed with uniform thermal conductivity to deliver consistent temperature along the wound. For cooling therapy, the cooling channel is configured to maintain a uniform cooling effect throughout its length. For electrical stimulation, the electrodes or conductive wires are configured to deliver uniform current density along the wound edges. This uniform distribution without gradient ensures consistent therapeutic effect across the entire wound site for optimal healing outcomes.
[0085] In another embodiment, the detachable controller comprises power sources, control circuitry, and driving circuits, whereas the therapeutic tube houses one or more stimulation elements such as LEDs, ultrasound transducers, heating elements, or vibration actuators. In this configuration, the detachable controller provides power and control signals to control and regulate the operations of one or more stimulation elements.
[0086] The first adhesive patch and the second adhesive patch may include therapeutic tubes configured for the same therapy modality or for different modalities, thereby enabling combined or sequential therapies under control of the detachable controller. In an embodiment, the detachable controller is configured to independently control stimulation delivered through the therapeutic tube on the first adhesive patch and the therapeutic tube on the second adhesive patch, thereby enabling differential or asymmetric therapy on the two sides of the wound.
[0087] In an embodiment of the present invention, the one or more stimulation elements comprise a light source for providing phototherapy, an electrical stimulation element for providing electrical stimulation therapy, a heating element for providing heat therapy, a cooling element for providing cold therapy, a vibration element for providing vibration therapy, and an ultrasound element for providing ultrasound therapy.

The electrical stimulation element is configured to provide one or more types of electrical stimulation therapy, including Electrical Muscle Stimulation (EMS) therapy, Microcurrent therapy, Galvanic therapy, Transcutaneous Electrical Nerve Stimulation (TENS) therapy, and Radio Frequency (RF) therapy.
[0089] In EMS therapy, the electrical stimulation element delivers electrical impulses to stimulate muscle contractions, which promotes blood circulation and reduces muscle atrophy around the wound site.
[0090] In Microcurrent therapy, the electrical stimulation element delivers low-level electrical current in the range of 1 microampere (pA) to 1000 microamperes (pA) to stimulate cellular activity and promote tissue repair.
[0091] In Galvanic therapy, the electrical stimulation element delivers direct current to the wound site to promote ion transfer and enhance drug penetration through iontophoresis.
[0092] In TENS therapy, the electrical stimulation element delivers low-voltage electrical pulses to stimulate sensory nerves and reduce pain sensation at the wound site.
[0093] In RF therapy, the electrical stimulation element delivers radio frequency energy to the wound site to generate controlled heating in deeper tissue layers, promoting collagen production and tissue remodeling.
[0094] The electrical stimulation element includes electrodes configured to deliver the electrical energy to the wound site. In one embodiment, the electrodes are fabricated from silver or silver chloride. In another embodiment, the electrodes are fabricated from conductive hydrogel materials. In yet another embodiment, the electrodes are fabricated from carbonbased conductive materials. The electrode configuration and placement are optimized based on the type of electrical stimulation therapy to be delivered.
[0095] The microcurrent element is configured to deliver low-level electrical current to the wound site for electrical stimulation therapy. The microcurrent element delivers current in the range of 1 microampere (pA) to 1000 microamperes (pA).

The heating element may include a temperature sensor and a feedback control circuit in the detachable controller to maintain the desired temperature and prevent overheating.
[0097] The cooling element is configured to provide cooling therapy to the wound site. In an embodiment, the cooling element includes thermoelectric (Peltier) elements that transfer heat away from the wound site, or the cooling element includes embedded channels configured to carry a cooling medium such as water or air. The cooling therapy reduces inflammation, decreases pain sensation, and reduces swelling at the wound site.
[0098] The mechanical vibration element may include a micro-motor, such as an eccentric rotating mass (ERM) motor or a linear resonant actuator (LRA). The mechanical vibration element is configured to generate vibrations at a frequency in the range of 50 Hz to 200 Hz. The amplitude of vibration is controlled by the detachable controller based on therapeutic requirements. The vibration therapy saturates sensory nerves to reduce pain at the wound site and stimulates local blood circulation.
[0099] The ultrasound element is configured to deliver ultrasound therapy to the wound site for deeper tissue penetration. The ultrasound element includes a piezoelectric transducer configured to generate ultrasound waves. The ultrasound element is configured to operate at a frequency in the range of 1 MHz to 3 MHz. The ultrasound therapy promotes tissue healing by increasing local blood flow, reducing inflammation, and stimulating cellular repair mechanisms.
[0100] In an embodiment of the present invention, the wound therapy device further comprises a drug delivery channel configured to deliver medicinal fluid to the wound site. The drug delivery channel includes microfluidic channels fabricated from biocompatible polymer materials such as polydimethylsiloxane (PDMS) or medical-grade silicone. The drug delivery channel is connected to a reservoir having a capacity in the range of 0.5 mL to 5 mL for storing the medicinal fluid.
[0101] In an embodiment, the reservoir for storing medicinal fluid is provided on thedetachable controller. In an embodiment, the drug delivery channel includes a piezoelectric micro-pump configured to provide precise control over fluid delivery rates. In another embodiment, the drug delivery channel includes an osmotic pump for passive fluid delivery. The flow rate is controlled by the detachable controller in the range of 0.1 mL / hour to 10 mL / hour, depending on the therapeutic requirements.
[0102] In an embodiment, the detachable controller includes a connection interface configured to connect to one or more stimulation elements housed within the therapeutic tubes. The connection interface includes optical coupling for connecting to light diffuser fibers, electrical contacts for connecting to microcurrent elements, heating elements, and cooling elements, fluid coupling for connecting to drug delivery channels, and mechanical coupling for connecting to vibration elements and ultrasound elements. The connection interface is designed to be flexible, such that the detachable controller can be used with a single stimulation element or a combination of multiple stimulation elements.
[0103] The connection interface on the detachable controller includes physical connectors configured to establish connections with the stimulation elements. The optical coupling for connecting to light diffuser fibers includes fiber optic connectors with lens alignment mechanisms to ensure efficient light transmission. The electrical contacts for connecting to microcurrent elements, heating elements, and cooling elements include gold-plated pins or spring-loaded contacts configured for reliable electrical connection. The fluid coupling for connecting to drug delivery channels includes Luer lock connectors or similar medical-grade fluid connectors with check valves to prevent backflow. The mechanical coupling for connecting to vibration elements and ultrasound elements includes threaded connections or snap-fit mechanisms configured for secure mechanical attachment.
[0104] The connection interface is configured to mate directly with an end region of the therapeutic tube so that optical, electrical, and fluidic paths are established without exposing internal components to the external environment. In an embodiment, the connection interface includes a sterile barrier and sealing gaskets configured to maintain a closed fluid pathway between the medicinal fluid channel and a reservoir located in the detachable controller. The interface may further include keyed alignment features ensuring that optical couplers align with light diffuser fibers, electrical contacts align with electrodes or conductive wires, and fluid connectors align with the medicinal fluid channel within the therapeutic tube.
[0105] The detachable controller operates in various therapy modes depending on thestimulation elements connected through the connection interface. In an embodiment, the controller operates in one or more modes, such as a phototherapy mode for controlling light emission through the light diffuser fiber, an electrical stimulation mode for controlling microcurrent delivery through the microcurrent element, a thermal therapy mode for controlling the heating element or cooling element, a drug delivery mode for controlling medicinal fluid flow rate and timing through the drug delivery channel, a vibration therapy mode for controlling mechanical vibration through the vibration element, an ultrasound therapy mode for controlling ultrasound delivery through the ultrasound element, or a combined therapy mode for simultaneous or sequential delivery of multiple therapies through multiple stimulation elements.
[0106] In an embodiment, the stimulation element comprises a light diffuser fiber housed within the therapeutic tube. The light diffuser fiber is configured to receive electromagnetic radiation from the plurality of LEDs in the detachable controller and distribute the electromagnetic radiation along a length of the wound site. The first adhesive strip has a first therapeutic tube with a first light diffuser fiber running along a length adjacent to the first lateral side of the wound. The second adhesive strip has a second therapeutic tube with a second light diffuser fiber running along a length adjacent to the second lateral side of the wound. The light emitted by the plurality of LEDs travels through the first light diffuser fiber and the second light diffuser fiber to provide light therapy to the wound.
[0107] The wound healing device provides benefits including reduced wound healing time, early mobilization of a patient, and excellent cosmetic results. The combination of wound closure functionality and light therapy delivery allows for faster recovery compared to conventional wound treatment methods.
[0108] When the first adhesive strip and the second adhesive strip are applied to the skin on either side of a wound, the adhesive strips provide uniform force along the wound edge. The uniform force distribution promotes proper wound alignment and facilitates the healing process.
[0109] Prior to describing the accompanying figures, it is clarified that the light therapy patch comprises at least one therapeutic tube positioned along an edge of the first adhesive strip, the second adhesive strip, or both adhesive strips adjacent to the wound site. The therapeutic tube forms a longitudinal housing configured to contain a drug delivery channel and one or more components associated with physical therapy modalities. The therapeutic tube is arrangedsubstantially parallel to the wound edges such that therapeutic stimulation and / or medicinal delivery occurs along the length of the wound while the adhesive strips perform mechanical approximation of the wound margins.
[0110] The therapeutic tube functions as an integrated conduit configured to accommodate both a medicinal fluid channel and at least one element associated with physical therapy delivery. In one arrangement, the medicinal fluid channel occupies a first lumen of the therapeutic tube while a passive delivery member corresponding to a stimulation modality occupies a second lumen. In another arrangement, the medicinal fluid channel and the therapy transmission element may be arranged concentrically or in parallel within a common lumen separated by internal partitions. This integrated configuration enables simultaneous or coordinated delivery of medicinal agents and physical therapy along substantially the same region adjacent to the wound edges.[OHl] In a first implementation, the therapeutic tube houses one or more passive delivery members corresponding to stimulation sources located in the detachable controller. The passive delivery members include, for example, light diffuser fibers for phototherapy, conductive wires or electrodes for microcurrent therapy, thermal conduction members for heating or cooling therapy, mechanical transmission members for vibration therapy, or acoustic transmission media for ultrasound therapy. The detachable controller contains the active stimulation elements and supplies energy or drive signals to the passive delivery member through the connection interface.
[0112] In an alternate implementation, the therapeutic tube directly houses one or more stimulation elements, and the detachable controller provides a power supply, control signals, and operational regulation to such stimulation elements. In this implementation, the therapeutic tube may contain LEDs, micro-heaters, cooling modules, vibration actuators, ultrasound transducers, or microcurrent electrodes, while the detachable controller governs parameters including intensity, frequency, duty cycle, and therapy duration.
[0113] The therapeutic tube may be provided on only one of the first adhesive strip or the second adhesive strip, or on both adhesive strips as respective therapeutic tubes. The therapeutic tubes on the two adhesive strips may be configured for identical therapy modalities or for different modalities to enable combined or sequential therapies. The configuration of the therapeutic tube is independent of the mechanical fastening structure of the light therapy patch and does not interfere with the wound closure function.
[0114] FIG. 1 illustrates a perspective view of the wound healing device 100 comprising a light therapy patch 102 and a detachable controller 114. The light therapy patch 102 is configured for placement on the skin surrounding a wound site, and the detachable controller 114 is removably coupled to the light therapy patch to provide therapeutic stimulation and operational control.
[0115] The light therapy patch 102 comprises a first adhesive strip 104 and a second adhesive strip 106 configured to be positioned on opposite sides of the wound. The first adhesive strip 104 and the second adhesive strip 106 are interconnected by a plurality of fastening members 112 configured to approximate the wound edges and maintain the wound in a closed or semiclosed condition.
[0116] At least one of the first adhesive strip 104 or the second adhesive strip 106 includes a therapeutic tube positioned along an edge facing the wound site. The therapeutic tube extends longitudinally along the respective adhesive strip and is configured to cooperate with the detachable controller 114 for delivery of one or more physical therapies and / or medicinal agents.
[0117] The detachable controller 114 comprises a housing accommodating power sources, control circuitry, and interface components. The detachable controller 114 is connected to the light therapy patch 102 through a connection interface 128 that enables optical, electrical, fluidic, or mechanical coupling depending on the therapy modality implemented in the therapeutic tube.
[0118] The detachable configuration allows the light therapy patch 102 to be disposable, while the detachable controller 114 is reusable with multiple patches. This arrangement reduces electronic waste and treatment cost while enabling delivery of advanced therapeutic functions in conjunction with mechanical wound closure.
[0119] FIG. 2 illustrates a top view of the wound healing device 100 applied around a wound site 120. The first adhesive strip 104 is positioned on a first side of the wound site 120, and the second adhesive strip 106 is positioned on an opposite side, with the fastening members 112 extending between the strips to draw the wound edges toward each other.
[0120] The first adhesive strip 104 includes a first therapeutic tube 130a extending along an inner longitudinal edge adjacent to the wound site 120. The second adhesive strip 106 may include a second therapeutic tube 130b extending along the opposing inner edge. In some embodiments, the therapeutic tube is provided only on one of the adhesive strips, while in otherembodiments, therapeutic tubes are provided on both adhesive strips to enable bilateral therapy delivery.
[0121] The first therapeutic tube 130a and the second therapeutic tube 130b are arranged substantially parallel to the wound margins so that therapeutic stimulation and / or medicinal delivery occurs along the length of the wound while the adhesive strips perform mechanical closure. The positioning of the therapeutic tubes enables uniform treatment without obstructing visual access to the wound site 120.
[0122] The detachable controller 114 is coupled to the light therapy patch 102 at an end region through the connection interface 128. The plan view of FIG. 2 shows that the connection interface 128 is located away from the wound site 120 so that the detachable controller 114 does not interfere with the approximation of the wound edges or with patient movement.
[0123] FIG. 3 illustrates an exploded view showing individual components of the wound healing device 100, in accordance with an embodiment of the disclosure. The exploded view depicts the spatial relationship between components of the wound healing device 100. The exploded view shows the first adhesive strip 104 and the second adhesive strip 106 separated from each other, each adhesive strip carrying a therapeutic tube positioned along a respective inner edge. The light diffuser fibers are shown as elongate members configured to be received within the therapeutic tubes. The fastening members 112 are shown in their individual positions along the lateral edges of the adhesive strips. The detachable controller 114 is separated from the light therapy patch 102, illustrating the connection interface 128 between the detachable controller 114 and the therapeutic tubes. The exploded view demonstrates the layered and modular construction that enables wound closure, together with the delivery of one or more physical therapies.
[0124] The first therapeutic tube 130a, associated with the first adhesive strip 104, and the second 130b therapeutic tubes associated with the second adhesive strip 106 are configured as common housings for multiple functional elements. Each therapeutic tube is configured to contain a drug delivery channel and one or more passive delivery members corresponding to stimulation modalities, including phototherapy, microcurrent therapy, vibration therapy, heating therapy, cooling therapy, or ultrasound therapy. The exploded view illustrates that the light diffuser fiber is inserted into the therapeutic tube rather than being directly embedded in the adhesive strip.
[0125] In an embodiment relating to the assembly of the light therapy patch, the therapeutictube is first fabricated with one or more internal lumens, after which the selected components are inserted into the tube. Light diffuser fibers, electrodes, conductive tracks, or other passive delivery members may be introduced into the tube through an insertion process followed by fixation using medical-grade adhesive or thermal bonding. The therapeutic tube containing the inserted components is subsequently attached to the first adhesive strip or the second adhesive strip such that the tube extends longitudinally along the inner edge of the strip. The assembly process maintains the flexibility of the adhesive patch while protecting the internal components from mechanical stress and contamination.
[0126] In an embodiment, the therapeutic tube on either or both adhesive strips may include conductive wires or electrodes for microcurrent therapy, thermal conductive elements for heating or cooling therapy, mechanical transmission members for vibration therapy, or acoustic transmission media for ultrasound therapy. These elements remain passive within the light therapy patch while the active sources and driving circuits are located in the detachable controller 114.
[0127] The wound healing device 100 may include structural enhancements such as a flexible patch design configured to conform to curved body surfaces, multiple size configurations, and a modular design configured to allow connection of multiple patches together for treatment of larger wounds. The detachable controller 114 may include a quick-release mechanism configured to allow rapid attachment and detachment from the therapeutic tubes without removal of the adhesive strips from the skin.
[0128] FIG. 4 illustrates a detailed cross-sectional view of an adhesive strip showing the therapeutic tube and a medicine delivery channel 126 for medicinal fluid delivery, in accordance with an embodiment of the disclosure. The cross-section reveals that the therapeutic tube 130 is positioned along a lateral edge of the adhesive strip facing the wound site 120 and forms a dedicated conduit independent from the adhesive substrate.
[0129] The therapeutic tube 130 defines an internal lumen within which a light diffuser fiber 132 is housed. The tube wall is formed from a flexible and optically transmissive material such that electromagnetic radiation received from the detachable controller is emitted toward the wound while the fiber remains mechanically protected.
[0130] In an embodiment, the therapeutic tube 130 is fabricated from a transparent or optically transmissive material to facilitate transmission of light for phototherapy. The transparent material allows electromagnetic radiation from the light diffuser fiber to pass through the tubewall and reach the wound site 120. In another embodiment, the therapeutic tube 130 has a partially transparent configuration wherein a lower surface of the therapeutic tube 130 facing the skin is fabricated from transparent material, while an upper surface of the therapeutic tube 130 facing away from the skin is fabricated from opaque material. This configuration directs the light toward the wound site 120 while preventing light emission in the opposite direction, thereby improving therapeutic efficiency and reducing light wastage. The transparent portion of the therapeutic tube 130 may be fabricated from optically clear silicone, transparent polyurethane, or other biocompatible transparent polymers.
[0131] The therapeutic tube 130 is configured in one of several attachment configurations with respect to the adhesive strips. In one embodiment, the therapeutic tube 130 is permanently embedded within the first adhesive strip 104 and the second adhesive strip 106 during manufacturing. In this embedded configuration, the therapeutic tube 130 is integrated into the adhesive strip structure through adhesive lamination, thermal welding, co-extrusion, or overmolding, and is disposed of together with the adhesive strips after treatment. In another embodiment, the therapeutic tube 130 is removably attached to the first adhesive strip 104 and the second adhesive strip 106. In this removable configuration, the therapeutic tube 130 is secured to the adhesive strips using detachable fasteners, snap-fit connections, or friction-fit channels, allowing the therapeutic tube 130 to be detached from the adhesive strips after treatment. The removable configuration enables reuse of the therapeutic tube 130 with new adhesive strips, thereby reducing waste and cost. In yet another embodiment, the therapeutic tube 130 is replaceable, wherein the therapeutic tube 130 is configured to be removed from the adhesive strips and replaced with a new therapeutic tube 130 or a therapeutic tube 130 configured for a different therapy type. The replaceable configuration allows a user or healthcare provider to select and install a therapeutic tube 130 housing passive delivery members suited for a specific therapy, such as replacing a therapeutic tube 130 with a light diffuser fiber with a therapeutic tube 130 with electrodes for electrical stimulation therapy. The embedded, removable, and replaceable configurations provide flexibility in selecting the appropriate therapeutic tube 130 configuration based on treatment requirements, cost considerations, and sustainability preferences.
[0132] The therapeutic tube 130 further houses one or more medicine delivery channels 126 configured for delivering a medicinal fluid to the wound site 120. The medicine delivery channel 126 extends along the length of the therapeutic tube and is configured for controlled delivery of medicinal fluid from a reservoir located in the detachable controller to the woundmargins.
[0133] In addition to the light diffuser fiber and drug delivery channel, the therapeutic tube 130 may house a passive delivery member associated with other therapies, including electrodes for microcurrent therapy, thermal elements for heating or cooling, mechanical members for vibration therapy, or ultrasound transmission media.
[0134] The passive delivery member for each therapy type is fabricated from materials optimized for the specific therapy. For phototherapy, the light diffuser fiber is fabricated from polymethyl methacrylate (PMMA) or silicone optical fiber with light scattering particles or surface modifications for uniform light distribution. For electrical stimulation therapy, the passive delivery member comprises metal wires or electrodes fabricated from silver, silver chloride, stainless steel, or conductive hydrogel materials. For heat therapy, the passive delivery member comprises a thermal conductive element such as a metal strip fabricated from copper, aluminum, or other thermally conductive materials, or resistive heating wires fabricated from nichrome or carbon-based materials. For cooling therapy, the passive delivery member comprises cooling channels fabricated from thermally conductive polymers or a thermal conductive element. For vibration therapy, the passive delivery member comprises mechanical transmission elements fabricated from rigid or semi-rigid polymers configured to transmit vibrations from the vibration source in the detachable controller 114. For ultrasound therapy, the passive delivery member comprises acoustic transmission media fabricated from materials with acoustic impedance matched to skin tissue for efficient ultrasound transmission.
[0135] In a further embodiment, the therapeutic tube 130 may directly house one or more active stimulation elements instead of a passive delivery member. The active stimulation elements positioned within the therapeutic tube may include LEDs for phototherapy, microheaters, thermoelectric cooling modules, vibration actuators, ultrasound transducers, or microcurrent electrodes. Electrical leads from the active stimulation elements extend to the connection interface for coupling with the detachable controller, which supplies power and control signals. Locating the active stimulation elements within the therapeutic tube enables localized generation of therapeutic energy along the wound edges while retaining centralized regulation through the detachable controller.
[0136] The first adhesive strip 104 and the second adhesive strip 106 run parallel to each other and are positioned on opposing lateral sides 122 and 124 of the wound. The therapeutic tubes provided on either or both adhesive strips extend parallel to the wound margins so that therapyis delivered substantially along the wound edges.
[0137] The fastening member 112 is configured to adjust a gap between the first adhesive strip 104 and the second adhesive strip 106. Adjustment of the gap controls the relative spacing between the therapeutic tubes positioned on the adhesive strips and thereby regulates the region over which therapy and medicinal delivery occur.
[0138] Tightening of the fastening member 112 draws the adhesive strips together and brings the therapeutic tubes on either side closer to the wound, enabling simultaneous mechanical closure and targeted therapy along the wound edges.
[0139] The adjustability provided by the fastening member 112 accommodates wounds of varying widths while maintaining the therapeutic tubes in optimal positions for delivery of electromagnetic radiation, electrical stimulation, vibration, thermal energy, ultrasound, or medicinal fluid.
[0140] FIG. 5 illustrates a detailed view of the fastening member 112 showing the adjustment mechanism for controlling the gap between the first adhesive strip 104 and the second adhesive strip 106. The fastening member includes engagement elements configured to connect to the adhesive strips and an adjustment mechanism that allows a user to increase or decrease tension between the strips. Manipulation of the fastening member causes the adhesive strips, and consequently the therapeutic tubes carried by the strips, to move toward or away from each other.
[0141] FIG. 6 illustrates a schematic block diagram of the detachable controller 114, in accordance with an embodiment of the disclosure. As shown in FIG. 6, the detachable controller 114 comprises a processor unit 144 configured to regulate operation of the wound healing device 100. The block diagram depicts functional components, including a power supply module 134, a driver circuit 136, one or more stimulation elements 138, a communication interface 140, and a user interface module 142, wherein the components are operatively coupled to enable coordinated control of light therapy delivery.
[0142] The schematic diagram further illustrates that the detachable controller 114 includes a connection interface 128 configured to couple with the light diffuser fibers and, in certain embodiments, with the medicine delivery channel 126 for medicinal fluid delivery. The connection interface 128 may provide optical coupling, electrical coupling, or a combination thereof, to transmit electromagnetic radiation and control signals from the detachable controller 114 to the light therapy patch 102.
[0143] In one embodiment represented by FIG. 6, the plurality of LEDs 116 constituting the active stimulation elements is housed within the detachable controller 114, and electromagnetic radiation generated therein is delivered to the wound site 120 through the light diffuser fibers 132. In an alternate embodiment, the active stimulation elements may be positioned on the light therapy patch 102 or within the therapeutic tube, while the detachable controller 114 provides power regulation and control functionality for the stimulation elements.
[0144] The block diagram further shows that the detachable controller 114 may include sensor inputs configured to receive feedback relating to temperature, light intensity, battery status, or fluid delivery parameters. Such feedback signals may be processed by the microcontroller to dynamically adjust treatment parameters during operation of the wound healing device 100.
[0145] FIG.7A illustrates a close-up view of the wound healing device 100 applied to a wound site 120 on a forearm, in accordance with an embodiment of the disclosure. As shown in FIG.7A, the first adhesive strip 104 and the second adhesive strip 106 are positioned on opposing lateral sides of the wound, with the fastening members 112 extending across the wound to approximate the wound edges.
[0146] The illustration demonstrates that the light diffuser fibers 132 are positioned adjacent to the wound site 120 such that electromagnetic radiation is directed substantially toward the tissue region requiring therapy. In embodiments where a therapeutic tube is provided, the tube may extend along one or both adhesive strips to enable localized medicinal fluid delivery in conjunction with light therapy.
[0147] FIG. 7A further depicts that tightening of the fastening members 112 reduces the gap between the adhesive strips and correspondingly adjusts the relative position of the light diffuser fibers 132 with respect to the wound site 120. This configuration enables simultaneous mechanical closure and therapeutic stimulation of the wound.
[0148] FIG. 7B illustrates a side perspective view of the wound healing device 100 of FIG.7A applied to a forearm, in accordance with an embodiment of the disclosure. The side perspective view demonstrates conformance of the light therapy patch 102 to a curved anatomical surface while maintaining alignment of the light diffuser fibers 132 along the wound edges.
[0149] As illustrated, the detachable controller 114 is coupled to the light therapy patch 102 at a peripheral location so as not to interfere with the wound site 120. The perspective view further demonstrates that the device 100 maintains a compact and ergonomic profile suitable forambulatory use by a patient.
[0150] FIG. 8 illustrates a flowchart depicting a method of using the wound healing device 100 to provide light therapy to a wound, in accordance with an embodiment of the disclosure. The method comprises a step 202: positioning the first adhesive strip 104 on a first lateral side 122 of the wound and positioning the second adhesive strip 106 on a second lateral side 124 of the wound, step 204.
[0151] The method further comprises a step 206: actuating the fastening member 112 to adjust a gap between the adhesive strips so as to approximate wound edges and position the light diffuser fibers 132 proximate to the wound site 120.
[0152] The method additionally comprises step 208: connecting the detachable controller 114 to the light therapy patch 102 through the connection interface 128, and step 210: activating the controller 114 to deliver electromagnetic radiation through the light diffuser fibers 132. In embodiments including a therapeutic tube, the method may further comprise initiating delivery of a medicinal fluid in coordination with light therapy.
[0153] The method may further include adjusting one or more treatment parameters selected from intensity, wavelength, duty cycle, treatment duration, or fluid flow rate based on user input or pre-programmed protocols stored within the detachable controller 114.
