ABSTRACT
Objective@#We determined the diagnostic accuracies of the mydriatic, monoscopic, iPhone 6s+ optic nerve photographs with a 20D lens and the Melbourne Rapid Fields (MRF) visual fields iPad application.@*Methods@#This was a prospective, cross-sectional, single-center study involving 47 non-glaucomatous and 49 glaucomatous eyes. Each eye underwent 2 visual field tests: MRF iPad application and the Humphrey Field Analyzer (HRF). Mydriatic photographs of the fundus were taken with two devices: an iPhone 6s+ combined with a 20 D lens and the Visucam 500 fundus camera. All printouts were evaluated by 2 independent, masked glaucoma specialists. Diagnostic accuracies between the modalities were computed. Agreements between different parameters of both devices were analyzed using Cohen’s kappa test.@*Results@#Smartphone-based (iPhone 6s+) fundus photos had an overall sensitivity of 100%, specificity of 89.36%, positive predictive value (PPV) of 89.36% and negative predictive value (NPV) of 100%, with all kappa values between graders of each parameter above 0.61. Tablet-based Melbourne Rapid Fields test had a sensitivity of 81.82%, specificity of 86.54%, PPV of 83.72% and NPV of 84.91%, showing good agreement with the HRF with a kappa value of 0.68 ± 0.07.@*Conclusion@#Smartphone-based fundus photography and tablet-based visual field tests are comparable to the standard fundus photos and visual field tests in evaluating the optic nerve and visual field. These portable devices are reliable and appropriate tools for diagnosing glaucoma and can be used for documentation and testing in remote areas and in a wider range of settings.@*@#

Objective:To research and design a wearable system for intelligent health monitoring and guidance of diagnosis and treatment so as to real-timely monitor the parameters of main vital signs of wearers and to achieve the intelligent health monitoring and guidance of diagnosis and treatment for wearers.Methods: The microsensor technique was its core, and blue tooth, 3G and (or) 4G mobile data communication function were applied in the design. And the vital signs of wearers were gathered, and threshold value was set to forewarn the warning. And then the data of vital signs were sent to cloud data platform of remote distant, and these data could be real-timely applied by doctor in diagnosis and treatment. Besides, the voice communication and GPS functions were integrated so as to got guidance of diagnosis, treatment and deliverance.Results: The system can real-timely collected, transfer and save the vital signs of wearers and forewarn abnormal vital signs of them. At the same time, the voice guidance and positioning could be implemented, and these function could actively forewarning at necessary time, therefore, it could timely treat and cure for wearers. Besides, it could provided speech communication function to achieve health monitoring and remote distance guidance for wearers.Conclusion: The system is convenient to wear and possesses series of powerful functions, and it has very high practical value for those with chronic ill or with special operations.
ABSTRACT
Objective To establish a regional remote imaging diagnosis platform to solve the problems in medical treatment of the population in remote areas and etc as well as the non-balanced medical resources distribution.Methods Standardization transform of non-standard PACS images and texts was executed with PACS platform,DICOM and HL7 heterogeneous module. KM-SES remote diagnosis system was used to integrate the components of clinical operation, communication network, database and etc so as to construct a regional imaging platform.Results The platform standardized the imaging process and quality control inside and outside the hospital,and contributed to shortening the treatment time and reducing the vacancy rate. Conclusion The platform implements remote consultation,diagnosis and examination appointment,and facilitates the medical service to the population in remote areas.[Chinese Medical Equipment Journal,2018,39(5):50-54,67]

ABSTRACT
Objective:In order to achieve the use of community medical care and branch doctor resources, to provide monitoring of remote diagnosis, providing more convenient, safe and efficient medical service for patients and hospital objective. Methods:Multi parameter remote monitoring system design of special model of WIFI wireless technology, including special new WIFI module, wearable multi parameter telemetry monitor, wireless relay box network and medical monitoring software, testing and data transmission of ECG, respiration, blood oxygen using a wireless network, can the patient monitoring in normal life condition. Results:Whenever and wherever possible the electrophysiological data sent to the hospital, the doctor can according to the electrophysiological data of the patient for remote diagnosis and further treatment. The accuracy of the stability, the reliability of the system and the parameters of the tested strictly, data transmission accurate rate reaches more than 98%. Conclusion: The patients and doctors have been received good feedback, clinical trials, has very practical clinical significance.
ABSTRACT
Objective To transmit and browse DICOM images in HIFU remote diagnosis system in Web.Methods Mix-patterned programming of.NET and VC++ was used to create a multi-layers architecture.Results The online compression and web browsing of DICOM images were realized.Conclusion Treatment can be livingly played back and suggestions were proposed for doctors.Medical service in high quality can be provided for remote patients.[Chinese Medical Equipment Journal,2008,29(3):39-41]
