In view of the flaw of artificial guardianship that exists in the medical transfusion guardianship process at present, this paper develops a kind of intelligent transfusion guardianship meter based on the wireless sensor network. It is compose of the following components, including the infrared detection module, ZigBee wireless transmission unit taking CC2530 as the core controller and step motor control module. Adopt the operating system of TinyOS and nesC, which faces wireless sensor network, to carry on the software design. This kind of intelligent transfusion guardianship meter, based on the wireless sensor network, is easy to operate, and may reduce the occurrence of transfusion accidents effectively.
