Abstract: The photo therapy apparatus of the present invention comprises one or more light sources which are integrated with a breast pump for providing photo therapy treatment to the breast and nipple of women during pumping of breast milk. The light sources can be lasers, light emitting diodes (LEDs), lamps, or any other types of light sources which produce therapeutic light in a desired wavelength range. The therapeutic light is delivered through the breast-shield or flange of the breast pump to the breast and nipple and produces a variety of photochemical processes, e.g. increase of ATP (adenosine triphosphate), triggering of photo neurological response and activation of enzymes, changes in local pressure, increases in temperature, and deformation of cellular membranes. Such photochemical reaction helps to reduce pain and promote healing of nipple lesion and in the meantime enhance yield of breast milk.

Abstract: This invention discloses an improved laser induced breakdown spectroscopy (LIBS) apparatus and method for the detection of mineral and metal contamination in liquid samples. The mineral and metal contaminant is first collected by filtering the liquid sample with a membrane filter. The membrane filter with the mineral and metal contaminant is then measured by a LIBS apparatus. The LIBS apparatus is based on a high repetition rate pulsed laser. The laser produces a train of laser pulses at a high repetition rate in the kHz (or even higher) range. When the laser beam hits the surface of the membrane filter, it generates several thousands of micro-plasma emissions per second. Synchronized miniature CCD array optical spectrometer modules collect the LIBS signal from these micro-plasma emissions. By adjusting the integration time of the spectrometer to cover a plurality of periods of the laser pulse train, the spectrometer integrates the LIBS signal produced by this plurality of laser pulses. Hence the intensity of the obtained LIBS spectrum can be greatly improved to increase the signal-to-noise ratio (SNR) and lower the level of detection (LOD).

Hence the intensity of the obtained LIBS spectrum can be greatly improved to increase the signal-to-noise ratio (SNR) and lower the limit of detection (LOD). In addition, the influence of pulse to pulse variation of the laser is minimized since the obtained LIBS spectrum is the spectrum of a plurality of micro-plasma emissions produced by a plurality of laser pulses. The high repetition rate laser also makes it possible to measure the LIBS signal at a short and a long integration time and mathematically combining the two spectra to obtain a LIBS spectrum with enhanced dynamic range.
