Heater-scale for heating fluids for injection into a patient

摘要: A heater-scale having a curved supporting member upon which bag of fluid to be heated can placed, has distributed two-dimensional heating element affixed lower surface thereof. The is supported by load cell for generating an electrical signal proportional the weight on heater member, thermistor in contact with whose temperature maintained, and control system senses as well purpose nonlinearly adjusting current supplied removed from or variable added so maintain at predetermined temperature.
