In one example, an article is provided for use with an apparatus for generating an aerosol using an irradiative light source. The article has smokable material in combination with a transparent window through which light can pass. In another example, apparatus for generating an aerosol has an irradiative light source located in the apparatus. At least one optical component manipulates light emitted in use by the irradiative light source. A receptacle accommodates smokable material and receives light emitted in use by the irradiative light source. A transparent window is arranged between the receptacle and the at least one optical component. A combination of an apparatus for generating an aerosol and an article is also disclosed.

An infant warming system can include a platform for supporting an infant, at least two chest electrodes configured to connect to and detect cardiac potentials from a chest of the infant, an ECG monitor configured to receive the cardiac potentials from the at least two chest electrodes, a pulse oximeter device configured to determine an SpO.sub.2 for the infant, and a processor configured to determine one or more activation thresholds for the infant, wherein the one or more activation thresholds represent one or more target saturation levels for the infant. The processor can also compare the heart rate for the infant to a first heart rate threshold and compare the SpO2 for the infant to the one or more target saturation levels, adjust a display on a display device based on the comparisons, and generate a care instruction for a care stage based on the SpO2 of the infant.

A catheter device according to one aspect of the present invention includes: a tube to be inserted into a body; a light emitting unit, which is provided on a distal end side of the tube, and includes an infrared light emitting element configured to emit infrared light for verifying a position of the tube; a power supply line configured to supply electric power to the infrared light emitting element; and a conduction detection unit including a visible light emitting element configured to notify a conduction state between the power supply line and the infrared light emitting element by means of visible light. With the catheter device, operation of the light emitting unit can be visually checked before inserting the tube.

The present invention relates to a skin attachment comprising light emitting elements and a storage apparatus therefor. According to one aspect of the invention, there is provided a skin attachment, comprising: an attachment unit attached to skin of a user, wherein the attachment unit is capable of being bent and attached along a curved surface of the skin of the user; a light emitting unit disposed in the attachment unit, wherein the light emitting unit comprises at least one light emitting element; a diffusion unit configured to diffuse light from the light emitting unit, wherein the diffusion unit comprises scattering particles or microlenses; and a control unit disposed in the attachment unit and configured to control the light emitting unit.

Methods, systems, and devices are disclosed for therapeutic stimulation of targeted regions of the brain, improved delivery of exosomes across the blood brain barrier, or combinations thereof. An ultrasound transducer is used to target a region of therapeutic interest in a patient's brain. The transducer sonicates the targeted region, forming openings in the blood brain barrier or increasing local perfusion at the targeted region. Near-infrared light sources can further be applied to the targeted region to increase delivery of exosomes, either in combination with sonic transducers. In some embodiments, near-infrared light sources are applied to the targeted region to regulate neurobiological function or encourage neurotherapeutic effects, either alone or in combination with the administration of exosomes or therapeutic agents to the patient.

One aspect of the present disclosure is directed to a device for providing light to the surface of a subject, comprising an array of a plurality of light emitting modules, wherein the plurality comprises four light emitting modules, each module of the plurality is flexibly connected to another module of the plurality, and two of the modules of the plurality comprise a polygonal perimeter having 4, 5, or 6 major sides, a light source, and a longest apex-to-apex dimension for a module of 5-50 millimeters, and, optionally, a non-adherent member configured to be adjacent to the subject.

A wound dressing and method of use is provided that increases healing of tissues by targeting damaged tissue at a predetermined wavelength. The device includes the use of a negative pressure bandage, a flexible light sheet, and one or more bioactive marine extracts. Light emitted from the flexible light sheet penetrates through the bandage to target damaged tissue, which accelerates the wound healing process and works synergistically with the negative pressure bandage and bioactive marine extracts such as collagen fibers, alginate, chitosan and fucoidan, or any combination thereof to accelerate healing.
