Tube apparatus for warming intravenous fluids within an air hose
First Claim
1. An apparatus for warming IV fluids with a warmed airflow during delivery from an IV fluid source to a patient, comprising;
- an air hose for connection to a source of warmed air at a first end and including a nozzle at a second end;
an inlet tube segment for connection to said IV fluid source;
an outlet tube segment for transporting said IV fluid;
at least one helically coiled warming tube segment in fluid communication with said inlet tube segment and said outlet tube segment;
at least a portion of the at least one helically coiled warming tube segment kept within said air hose; and
means acting between the air hose and the at least one helically coiled warming tube segment for keeping the at least one helically coiled warming tube segment within the air hose.

Abstract
An IV fluid warmer that utilizes a warmed airstream supplied through an air hose to heat IV fluid flowing through one or more helically coiled warming tubes positioned within the air hose. In one embodiment, support unit keeps the one or more warming tubes in the air hose, exposed to the warmed airflow. A nozzle provided on the distal end of the air hose has an outer housing and an inner ring slidably positioned therein. The outer housing includes an outer slot and the slidable inner ring includes an inner slot. When aligned, the support unit can be inserted through the inner and outer slots and the inner ring may be rotated to lock the support unit into position within the air hose. In another embodiment, helically coiled warming tube is self-supporting within the air hose. The IV fluid warmer can achieve high heating rates and low flow resistance in this configuration. Furthermore, it can utilize an airstream source of heat such as that conventionally used with inflatable thermal blankets.
