A method and apparatus for pressure infusion and
temperature control of infused liquids includes a receptacle for receiving a liquid-filled bag containing intravenous solution or other liquid and an
inflatable pressure device. The
inflatable pressure device is disposed within a pressure device bag and is positioned
proximate the liquid-filled bag in the receptacle. The
inflatable pressure device expands within the pressure device bag upon inflation and exerts pressure on the liquid-filled bag. A
heating element may be disposed on the inflatable pressure device bag to heat the liquid-filled bag to a desired temperature. The liquid may alternatively be maintained at a desired temperature, while flowing to a patient via a heating
assembly disposed along a tube. The heating
assembly includes a sleeve having a slot for receiving the tube and a plurality of individually controlled heaters. An
infrared sensing device is mounted
proximate a
drip chamber to ascertain a drip count, while a temperature sensor is disposed within a holder that is positioned toward the
entry site on a patient. A heat controller controls the heaters based on a drip count, while a safety controller disables heater operation in response to
liquid temperature exceeding the desired temperature. Thus, the safety controller and heat controller, in combination, control the heating
assembly heaters based on
liquid temperature and flow rate, respectively. Alternatively, the liquid-filled bag may be heated to a desired temperature whereby the heating assembly includes a single heater controlled by a controller to maintain the liquid at the desired temperature during infusion of the liquid into a patient.
