摘要： An apparatus comprises a spectrophotometer system configured to measure light absorbance by a tear sample, a refractometer system configured to measure refractive index of the tear sample, and an evaluation unit programmed to calculate an osmolarity of the tear sample based on the measured absorbance and refractive index and stored calibration curves. The spectrophotometer and refractometer systems may share a common prism contacted by the tear sample during measurement. The evaluation unit may be programmed to carry out steps of a method for determining osmolarity of the tear sample in accordance with the invention. The osmolarity of the tear sample may be used as an indicator in diagnosing dry eye.

摘要： A syringe pump and associated computer are provided to achieve an ultra-low flow rate. The computer may generate syntax commands to a motion controller of the syringe pump to displace a plunger by a selected number of steps or increments and pause a period of time before repeating the displace and pause steps. The cycle may be repeated until a desired end condition has been reached. The syringe pump and computer may be embodied as separate linked units or as a standalone unit wherein the computer is an embedded controller located within the syringe pump housing. The invention may also be embodied as a method for achieving ultra-low flow.
