Abstract
IV fluid is warmed while being intravenously-administered to a patient through an IV tube by positioning a portion of the tube at a warming location and flowing a heated gas past the warming location to heat the tube, which thereby heats the IV fluids flowing in the tube.
Claims32
An apparatus for warming IV fluid during delivery to a patient, which consists of:
- a source of IV fluid;
- a delivery tube connected to said source;
- a means for positioning a respective portion of the delivery tube for warming;
- a source of heated gas;
- and
- a convective means connected to the source of heated gas for warming the respective delivery tube portion by a flow of heated gas.
An apparatus for heating IV fluid during intravenous administration to a patient, consisting of:
- a tube for intravenously-administering IV fluid;
- a positioner for positioning the tube for heating;
- and
- a means for flowing a heated gas past the positioner to heat the tube.
A method for warming IV fluid during delivery to a patient using an apparatus including a source of IV fluid and a delivery tube connected to said source for intravenously-administering the IV fluid to the patient, the method comprising the steps of:
- positioning a respective portion consisting of the delivery tube at a warming location;
- and
- flowing a heated gas past said warming location to heat said delivery tube.
An apparatus for warming IV fluid during delivery to a patient, which comprises:
- a source of IV fluid;
- a delivery tube connected to said source;
- a convective means connected to the source of heated gas for providing a flow of heated gas;
- and
- a heat transfer mechanism consisting of a respective portion of the delivery tube and means cooperating with the convective means for positioning the respective portion of the delivery tube at the flow of heated gas.
An apparatus for heating IV fluid during intravenous administration to a patient, comprising:
- an IV tube apparatus including an IV fluid source and an IV tube for intravenously-administered IV fluid;
- a heat transfer mechanism consisting only of a portion of the IV tube;
- a positioner for positioning the heat transfer mechanism for convective heating;
- and
- a means for flowing a heated gas past the positioner to heat the IV tube portion.
