An amblyopia patch device including an eye patch, a light sensor attached to the eye patch, an alarm in communication with the light sensor, and an electronics system for triggering the alarm when the light sensor senses a light value above a pre-set threshold. A method of using the amblyopia patch device is also disclosed.

Dressing or bandage for protecting a wound accidentally incurred, surgical incision deliberately made in the skin, epidermal delivery of medication, or musculotherapy of a human being or animal, said bandage/dressing having the primary characteristic of being significantly atraumatic upon removal of same by virtue of a novel stringlike member that is intentionally incorporated into or debossed into the construction of said parent bandage/dressing in a multi-spiral geometry, said stringlike member firstly being pulled gently and progressively in multiple turns around the wound site or epidermal treatment area to in effect significantly reduce the area of remaining/undisturbed adhesive between the bandage/dressing and patient's skin before the bandage/dressing is peeled away from the skin in conventional manner and thus affording the patient a significantly less traumatic experience.

A bandage is formed of a film layer, an adhesive applied to the film layer, and an absorbent layer connected to the film layer. The absorbent layer comprises a compressed fabric soaked in a fluid. A permeable membrane is disposed over the absorbent layer and creates an electrical charge when fluid from the absorbent layer passes through the membrane. The electricity generated by the osmosis flows to a plurality of light emitting diodes that are connected to the membrane through a battery. The LEDs emit UV light to disinfect a wound when a bandage is applied to the wound.

An applicator has a stem, one or more tips, and one or more chambers which may hold therapeutic or medicinal fluids. The applicator may be separated into two sections so the tips can be used independently. The fluids held in the chambers may be separated with one or more frangible walls which can be broken to release or mix the fluids. The tips are used as applicators for the therapeutic or medicinal effects produced by the fluids or the medicines contained in the cavity.

A device for promoting healing of an injury in a living being is provided. Such device is based upon an injury covering portion, which portion comprises an electroactive polymer, such as poled polyvinylidine difluoride (PVDF) or a copolymer of PVDF. The electroactive polymer has either pyroelectric properties, piezoelectric properties, or both.

A light therapy apparatus includes a pad comprising at least a first layer and a second layer and a side scattering light guide mounted between the first layer and the second layer and having a first end and a second end. The first end and the second end extend in parallel with each other externally from the pad, the side scattering light guide extends from at least one of the first end or the second end in a sinusoidal shape or an inward extending circular spiral between the first layer and the second layer, and at least one of the first layer or the second layer is translucent.

A dressing apparatus and methods for facilitating healing, the apparatus and methods involving a dressing member, an electromagnetically conductive element mechanically coupled with the dressing member, and a primary RFID device configured to transmit at least one output signal to the electromagnetically conductive element, to receive at least one return signal from the electromagnetically conductive element, and to provide an alert if the at least one return signal has a strength corresponding to at least approximately a threshold amount of fluid present in the dressing member, whereby healing is facilitated.

A kit of parts for use in treatment of tissue by a contained plasma and/or plasma products is disclosed. The kit of parts includes a plasma generating device for use with a membrane dressing attached to tissue requiring treatment. The plasma generating device comprises a first cavity with an opening at one end formed between a grounded electrode and a cathode such that, in use, an arc discharge between the cathode and the grounded electrode ionizes a feed gas to produce at the open end a thermal plasma. Furthermore, the plasma generating device also comprises a second cavity with an opening at one end formed between a high voltage electrode and a grounded electrode such that, in use, a dielectric barrier discharge between the high voltage electrode and grounded electrode ionizes a feed gas to produce at the open end a non-thermal plasma. The membrane dressing is suitable for covering tissue in use, such as a diabetic ulcer, and comprises a sheet of impermeable material configured for forming a plasma containment compartment adjacent to the tissue. The membrane dressing also comprises one or more input connectors configured to admit plasma and/or plasma products through the membrane dressing. The plasma generating device and the one or more input convectors of the membrane dressing are configured to allow the plasma generating device and the input connector to be directly coupled or indirectly coupled through a connector tube to allow fluid communication of the plasma and/or plasma products produced at the openings of the cavities of the plasma generating device through the membrane dressing to, in use, allow conduction of the produced plasma into the membrane dressing. Advantages of such a kit of parts may be that the membrane dressing does not need to be removed to inspect the progress of the wound, nor does it need to be removed and replaced to manage the exudate. Such advantages helps to mitigate the problems of wound aggravation and maceration typically associated with well-known wound dressings, and also helps to encourage and facilitate wound healing.

In some cases, a method of coating a wound dressing includes coating a wound facing side of a substantially flexible substrate of the wound dressing with a coating, the wound facing side of the substrate supporting at least one optical sensor and reducing and/or controlling surface texture of the coating to improve detection by the at least one optical sensor. In some cases, a wound dressing includes a substantially flexible substrate supporting at least one optical sensor, the at least one optical sensor including a light source and a detector configured to sense reflected light, a void in the substrate, the void positioned between the light source and the detector, and coating applied to the substrate and covering the at least one optical sensor. The void can prevent transmission of light emitted by the light source to the detector through the coating.

A system for applying negative-pressure therapy to an abdominal cavity. The system comprises: a tissue interface comprising a first contact layer and a second contact layer, each of the first contact layer and the second contact layer having perforations formed therein. The system also comprises a spacer layer disposed between the first contact layer and the second contact layer, the spacer layer configured to extend to different zones within the abdominal cavity. The system also includes a first sensor associated with the spacer layer and configured to acquire data associated with fluid at a first zone within the abdominal cavity and a first wireless transceiver associated with the first sensor and configured to transmit the data to an external therapy control device.
