A neural probe structure has a probe having a microfluidic channel. The probe is inserted into an inside of a subject. A body to which the probe is fixed has a fluid entrance communicating with the microfluidic channel. A cover element is fixed to the body to cover the fluid entrance. The cover element has a connecting opening to which an external conduit is connected, and a fluid delivery channel extending such that the connecting opening and the fluid entrance are in fluid communication. A fluid fed from the external conduit flows along the fluid delivery channel, goes into the fluid entrance, and is delivered to the subject through the microfluidic channel.

There is provided a method and apparatus for monitoring oil deterioration in real time. The method includes the steps of radiating light into an oil medium and measuring light intensities at red, green and blue wavelength ranges of the light after passing through a certain thickness of the oil. A ratio of the light intensity at the red wavelength range to the light intensity at the green wavelength range is computed by using the measured light intensities. These steps are repeated to monitor a change in the above ratio value in real time of oil use. The apparatus includes a light source means for radiating light into an oil medium, a color sensing means for measuring light intensities at red, green and blue wavelength ranges of the light that has passed through a certain thickness of the oil, and a control means for computing and monitoring a ratio of the light intensity at the red wavelength range to the light intensity at the green wavelength range, using the light intensities measured by the color sensing means.

There is provided a method and a device of monitoring oil oxidation in real time. The method of the present invention comprises the steps of: irradiating ultraviolet light into oil to be monitored; measuring fluorescence emission intensity of the oil in red, green and blue wavelength bands; determining one value measured in a relatively long wavelength band and the other value measured in a relatively short wavelength band among the fluorescence emission intensity measured in the red, green and blue wavelength bands; calculating a fluorescence emission ratio which is defined as a ratio of the value measured in the relatively long wavelength band to the value measured in the relatively short wavelength band; and monitoring a change in the fluorescence emission ratio. It is then determined whether the fluorescence emission ratio reaches a predetermined critical magnitude. When the fluorescence emission ratio reaches the critical magnitude, the necessity of replacing the oil with new one is indicated.
