1. Microwave apparatus for thawing liquid frozen in a plastic bag comprising:
- microwave means having a microwave cavity for receiving the plastic bag and a microwave power source for energizing the microwave cavity to thaw the frozen liquid in the bag;
holder means within the microwave cavity for retaining the plastic bag in a substantially vertical position and for shielding strategic areas of the plastic bag from microwave energy;
means fixed to the holder means within the microwave cavity for imparting a motion to plastic bag thereby agitating the thawing liquid in the plastic bag; and
temperature means for detecting the temperature of the thawing liquid in the bag and for deenergizing the cavity at a preselected temperature.

Abstract
The microwave heating apparatus consists of a microwave cavity, a energizing source, a mechanism for holding and agitating a load, and a temperature detector for continuously monitoring the temperature of the load. It is particularly useful for heating and quickly thawing frozen blood plasma or intravenous admixtures as needed. These must be thawed uniformly and to some preselected temperature so as not to destroy their effectiveness. It also helps to prevent wastage of the blood plasma thawed in anticipation of an emergency.
