At present before anesthesiologists infuse blood into a patient’s body, the blood
which is preserved in a blood bag and stored in a cold storage is warmed to the patient’s
body temperature. Some current practices in hospitals to prepare blood for infusion are
the use of a heat solder, warm water [1], the screw blood warmer [2], heater [3],
running water as well as leaving the blood bags to room temperature. The methods are
inefficient, time-consuming and inconvenient for the anesthesiologists. To improve
work efficiency of the medical staff, this research paper has therefore introduced a
higher efficiency blood warmer system. The system is portable and simple to operate.
The proposed blood warmer system utilizes two peltiers of two differing temperatures.
As one side of a peltier generates more heat than its other side, the hotter sides of the
two peltiers are facing the blood shaker of the blood-warming chamber. The
organization of this research paper is as follows: Section I is the introduction part and
Section II is concerned with the workings of the peltiers. The design and concept of the
proposed blood warmer system are respectively discussed in Sections III and IV.
Section V deals with the experimental results. The conclusions and future work are
provided in Section VI.
