Far distance medical system front end based on palm computer

The utility model relates to a far distance medical system front end based on a palm computer, which belongs to the application field of medical instrument and computer network, particularly the application technical field of portable far distance medical system front end. The utility model comprises a data collector and a palm computer which are mutually connected by a serial communication interface. The palm computer is also connected with a network interface; the data collector comprises an electrocardiogram electric pole, an electrocardiosignal amplifier, an electrocardiosignal A/D converter and a microcontroller which are orderly connected, and a sphygmomanometer interface which is connected with the microcontroller. The microcontroller adopts an MCS2051 chip, the sphygmomanometer interface adopts an LM393 chip, the A/D converter adopts an MAX1249 chip, and the serial communication interface adopts an MAX232 chip. The utility model solves the problem that the existing far distance medical system front end is large in volume and is inconvenient to carry; the utility model has convenient operation and high performance/cost ratio; meanwhile, the utility model can communicate with medical service center through a palm computer with network communicating and far distance co-operating ability.
