The present temperature monitor is comprised of a thermistor and a reference resistor connected to a capacitor in parallel. The capacitor is charged through the thermistor by a microcontroller to determine the thermistor charging time, discharged, and then charged through the reference resistor to determine a reference charging time. The thermistor charging time is divided by the reference charging time to determine the thermistor value, which is converted into an actual temperature by using a conventional algorithm. The microcontroller is programmed to activate various indicators to show the ambient temperature relative to one or more acceptable ranges, whether the temperature has reached the acceptable ranges within an acceptable time period, and whether the temperature has had an upward trend prior to reaching the acceptable ranges.

Temperature monitor for temperature sensitive products

A liquid medication dispenser apparatus which provides for user-friendly medication measurement and compliance. The apparatus measures and dispenses liquid medication doses and records the time and dose sizes for up to one year. The recorded information can then be downloaded to a personal computer for evaluation of patient compliance. A disposable, motor driven pump is used to provide a very wide range of medication dispensation volumes, while maintaining full accuracy and reducing the risks of patient errors as might occur with a manual dispense system.

A method for the enhanced accuracy in dispensing from a fluid roller dispensing pump, wherein a keyed one way insertable cassette with pump compressible tubing is utilized with the fluid dispensing pump. The cassette holds and maintains a compressible plastic tube adjacent a roller pump, whereby the rollers of the pump compress the tubing to draw and accurately dispense predetermined exact amounts of liquids into vials, hypodermics and the like for accurate medical and/or laboratory use, and wherein slightly improper placement still provides dispensing but with not always detectable inaccuracies. The cassette is provided with positive proper position indicator elements to ensure both proper orientation and complete locking engagement to ensure accurate pumping and dispensing. In a preferred embodiment the pump embodies current use sensors which determine if the cassette, which causes the pump to use more current, is present. A keyed one-way cassette fitting prevents improper placement.
