Development of CT and MRI enhanced scanning tracking monitor / 医疗卫生装备

ABSTRACT

Objective To develop a tracking monitor for patient vital signs after CT and MRI enhanced scanning so as to execute auto alarm in case of patient discomfort and allergic reactions.Methods The monitor composed of a sub machine,a principal machine and a large-screen display used ultra-low power digital blood oxygen plate LPDSPO2V1.4 and fingertip sensor to acquire data on blood oxygen saturation and heart rate,the acquired data were transmitted to the principal machine with NRF24L01 wireless transmission module, and then the principal machine executed data auto analysis, storage, auto alarm for out-of-limit data and sent the data to the display.Results The monitor could be used for checking blood oxygen saturation and heart rate as well as implement early warning against allergic reactions.One-year trials proved that there were no death in case 87 cases of minor allergic reactions and 3 severe ones occurred.Conclusion The monitor proves its safety and efficiency by decreasing the incidence rate of severe reactions after CT and MRI enhanced scanning,and thus is worthy promoting clinically.
