Visible-near infrared spectroscopy in burn injury assessment
ActiveUS20060155193A1Diagnostics using lightDiagnostics using spectroscopyBurning tissueFull thickness burn
A non-invasive method of characterizing burn injuries using near infrared spectroscopy is described. In the method, a beam of light is emitted into the burnt tissue portion at two or more different tissue depths. The spectra are then compared using multivariate analysis to determine diagnostic regions of the spectra. This information is used to categorize the burn. In some cases, the diagnostic regions correspond to wavelengths related to the hemodynamics of the tissue portion. The spectra can also be repeated over time, thereby allowing trends and changes in the spectra to be measured. This data is in turn used to categorize the burn as either a superficial burn, partial thickness burn, deep partial burn or a full thickness burn. Once the burn has been categorized, the clinician can intervene as needed to treat the burn.

In vivo port wine stain, burn and melanin depth determination using a photoacoustic probe
ActiveUS7322972B2Avoid introducingSurgical instrument detailsDiagnostic recording/measuringBurning tissueBurn tissue
A photoacoustic probe for port wine stain (PWS), burn and melanin depth measurements is comprised of optical fibers for laser light delivery and a piezoelectric element for acoustic detection. The probe induced and measured photoacoustic waves in acryl amide tissue phantoms and PWS skin in vivo. Acoustic waves were denoised using spline wavelet transforms, then deconvolved with the impulse response of the probe to yield initial subsurface pressure distributions in phantoms and skin. The waves were then analyzed for epidermal melanin concentration, using a photoacoustic melanin index (PAMI) related to the amount of laser energy absorbed by melanin. Propagation time of the photoacoustic wave was used to determine the depth of blood perfusion underlying necrotic, burned tissue. Thus, the photoacoustic probe can be used for determining PWS, burn and melanin depth for most patients receiving laser therapy.

The gas stove comprises a casing, a pot holder, a burner, a stove head, a base and a gas nozzle; the burner comprises a standing vortex area, a main flow area and a mixing area; the standing vortex area has effects of flame stabilization and combustion organization in the slow fire state; combustion organization is completely by the main flow area at the state above the slow fire and the standing vortex area together, and high-temperature gas or flames are formed to heat a to-be-heated vessel. The gas stove adopts the cavity flame stabilization technology and has the advantages of good ignition performance, high flame stability, wide combustion state range and the like. Besides, the combustion organization method capable of realizing grading and partitioning and the special structural form of the burner are adopted, two heating manners of flame heating and flameless heating (high-temperature gas heating) at the outlet of the gas stove can be realized, the gas stove has the advantages that the temperature of the high-temperature gas or flames can be adjusted continuously, and heating can be more uniform.
