Device and method for in vivo flow cytometry using the detection of photoacoustic waves

A photoacoustic flow cytometry (PAFC) device for the in vivo detection of cells circulating in blood or lymphatic vessels is described. Ultrasound transducers attached to the skin of an organism detect the photoacoustic ultrasound waves emitted by target objects in response to their illumination by at least one pulse of laser energy delivered using at least one wavelength. The wavelengths of the laser light pulse may be varied to optimize the absorption of the laser energy by the target object. Target objects detected by the device may be unlabelled biological cells or cell products, contrast agents, or biological cells labeled with one or more contrast agents.

Sound-based spirometer system

A sound-based spirometer system including a spirometer and an electronic device having a microphone. The spirometer includes an air inlet and an air outlet. The spirometer generates a sound as an unknown amount of air passes from the air inlet to the air outlet. The sound is recordable by the microphone, and the electronic device processes the sound to determine the volume and flow rate of the unknown amount of air.
