Household Multi-parameter Monitor

Household multi-parameter monitor is using electronic technology to guardianship object of various physiological parameters for conversion, transmission and feedback of modern medical instrument. This design is aimed at a hospital bedside monitors the household design. Household multi-parameter monitor the research convenient in family environment using the new concept of the monitor. This design includes physical inspection module, the data acquisition module, wireless transmission module and remote transmission module of this a few parts. This article through to Mega8 various function of microcontroller AVR realize as experimental basis, and actively using advanced wireless transmission module nRF401 to finish the design requirements.In physiological inspection module of the experimental process, using the patient simulator realize physiologic extraction, preamplifier, amplification, filter and trapped wave processes. In data acquisition and wireless transmission module of the experimental process, rely on the C language Mega8 control platform and realize through nRF401 chips for physiological parameters of three channels tour to the nRF401 sampling and fired at the receiving end. In the remote transmission module design experiments, rely on Internet network techniques to realize to family PC data remote transmission, and will eventually the result showed that in the remote PC.This paper mainly through the above a few parts of experiment and data compilation completed. In the design of each module, the key is how to realize the function of each module in the experimental process perfect unifies in together, form a system so as to obtain a final results and conclusions. Physiological module will be patient physiology signal acquisition and amplified, and then through the single-chip microcomputer control acquisition three channels electrical signal AD transform and control wireless transmission module launch, launch signal by the receiver to accept and transmitted to family PC. Family PC to results through the cable teleport to distal medical control room in the computer system monitoring function.This design through a series of experiments eventually finish all the above process, success will be displayed in the guardianship physiologic remote computer, realized the household multi-parameter monitor apparatus design functions, have certain application value.
