ABSTRACT
Objective To realize excellent remote medical treatment for patients.Methods The ECG monitoring module based on Bluetooth technology was designed.The ECG module and Bluetooth radio-frequency module,which possessed the function of data acquisition and simple processing,were connected through data wire to act as ECG terminal.By using C8051F020 and ROK 101 007 Bluetooth module,ECG Bluetooth transmission module read in HCI command through serial port,thus realizing mutual communication.VC++6.0 was used as developing tool to edit remote monitoring server programme running on the computers in monitoring center.Results ECG monitoring module could acquire ECG data in real time and transmit it to personal computers,and then send it to the monitoring center through Wide Band.In this way,real-time information exchange between doctors and users was realized.Conclusion This module makes full use of the advantages of Bluetooth technology and has strong practicability.
ABSTRACT
Objective To expand peripheral memory of DSP by using FMl8L08.Methods Because FMl8L08 not only can be randomly read in high speed,but is non-volatile and compatible with the pins of SRAM,the interface to TMS320F2812 was designed based on FMl8L08.Results FMl8L08 is used as TMS320F2812 peripheral memory expansion,instead of traditional separate ROM and RAM design,and be applied to the 12-lead ECG development.Conclusion This scheme can predigest software and hardware design complexity,enhance the system stabilization and decrease the power consumption.
ABSTRACT
The conventional invasive tissue blood oxygen content measurement is poor in continuity.The weakness of the signal,strong interference and random transmission of the photon in tissues make the measurement difficult.Recently,near infrared spectrum technology has been applied to tissue blood oxygen content measurement.This paper presents a hardware design method for tissue blood oxygen content measurement by near infrared spectrum technology.
ABSTRACT
The method and developing progress on 3D reconstruction technology based on medical image are introduced.Because 3D reconstruction technology is applied in observing bone tissue,cavum viscera and nerve tissue in clinic medicine,clear and vivid images in three dimensions can be reconstructed for clinical diagnosis.The 3D reconstruction technology based on medicine image has great application value in the course of diagnosis and therapy.[Chinese Medical Equipment Journal,2008,29(2):34-36]
ABSTRACT
In order to achieve real-time data acquisition and process, a signal acquisition and process system was designed based on USB2.0., in which DSP (Digital Signal Processor) acted as the core. Utilizing the powerful data processing capability of DSP, this system can extract biomedical signals from weak signals and then analyze them. At the same time, it realizes a high-speed and dependable transmission of data between DSP and PC.
