[Rewarming of infusions with the haemotherm]

A rewarming device for blood called Haemotherm from the firm Bosch was proofed for efficiency. This device working on the base of microwaves was able to warm up cold solutions to a certain temperature within two to three minutes. The effect of rewarming disappeared during the passage through the infusion tube. To get bodywarm solutions at the end of the infusion tube was impossible with this arrangement.
