Portable diagnostic system

摘要

A portable system for analysis of blood or other bodily fluids removable from a patient is disclosed. The system includes a temperature sensing device and a temperature control circuit. The temperature sensing device senses a temperature of a surface of a sensor substrate of a cartridge having an electrical heater device without direct contact with the cartridge or direct exposure to the heating device. The temperature sensing device also generates an electrical signal related to the sensed temperature. The temperature control circuit controls an electrical input to the heater device based on the sensed temperature and a designed control temperature.
