| In recent years, the number of the patients who are attacked by chronic kidney disease isbecoming bigger year by year. The illness that patients fall with chronic renal failuredisease will slowly exacerbate into Urinaemia, to this stage the main treatment option thepatients choose is either dialysis treatment or kidney transplant. Dialysis patients are neededto measure vital signs in every blood dialysis treatment, based on that the doctors determinethe treatment plan for the patients, they will deal with different emergency in the process ofdialysis, and they also evaluation of treatment effect. In order to raise efficiency and improvemanagement level, nowadays several blood dialysis centers in large general hospitals start todesign their own information management system, but that systems almost only managepatients’ duration and archives, rather than involving in collecting dialysis patients’ vitalsigns.This subject is a part of the design of information system based on small call center inhemodialysis, it is mainly responsible for collecting dialysis patients’ weigh blood pressureand body temperature, at the same time Single Chip Microcomputers transmit patients’information to doctor’s computer workstation, doctors and nurses in dialysis center can sharepatients’ treatment information by local area network. This sub-subject need designinghardware circuit and software, the hardware circuit includes: the design circuit of collectingpatients’ body weigh, the design circuit of collecting patients’ blood pressure and PWM, andthe design circuit of collect patients’ body temperature; and the design software includes:SPCE061A Single Chip Microcomputers’ software program, upper compute software aboutDialysis patients’ vital signs monitoring system. This subject has three innovation points asbelow:I designed the hardware and software of dialysis patients sale, it can take use of thetreatment ID card to measure patients’ weigh, and through COM-RS232the down SCM isable to send patients’ weigh to the upper PC, at once the upper PC will pass patients’treatment unit number and the added weigh to the down SCM, under receiving the message,the SCM will show and read these to the patients.I designed the patients’ vital signs collecting terminal, it can collect patients’ pressure,PWM and temperature, and through wireless part, nRF905se, send patients’ vital signs to theupper PC; once the upper PC receives the signs, the screen will display the signs with curveand show the change. Develop patients’ vital signs collecting system for hemodialysis center on the upper doctorcomputer, this system can receive the patients’ vital signs that comes from the down SCM,therefore it also can avoid inputting patients’ vital signs, that to say, it is able to improveefficiency of the workers in hemodialysis center.This subject achieves patients’ vital signs collecting in hemodialysis center., dataprocessing and upper computer patients’ information management, that to say, this system cancollect dialysis patients’ weigh, blood pressure, PWM, and body temperature, and save data inupper computer’s database. It can provide primary data for information system based on smallcall center in hemodialysis center, this primary data includes: dialysis patients’ weigh, bloodpressure, PWM, and body temperature, that information is patients management and patientscounsel basic data. |
