This article introduces a design of a medical folding fridge, which consists of three major components, base, folding frame and insulated cover. The base has a cooling system. The frame and cover are expanded during normal use and folded during storage or transportation. The device is compact, durable, transportable and well environmental adaptable. The system design is proved proper and the temperature inside is reliable. It is very suitable for temperature sensitive supplies stored in the medical emergency field.

Background: In 24 years, Expanded Programe on Immunization\r\n', u'(EPI) at Thua Thien Hue province achieve high efficiency, reduce remarkably infection rate of children disease in EPI. Objectives: Assessment of instruments and cold chain at City, District Health Center and Commune Health station. Assessment of knowledge and practice EPI of medical officers in districts and communes. Subjects and method: Instrument, cold chain system and officers at City, District Health Center and Commune Health station. Method: Cross-section descriptive study; Observe instruments and cold chain at Health stations and fill in available forms. Interview medical officers, observe practical manipulation and fill in available forms. Results: The rate of good knowledge varied from 61,64% to 94,55% and the rate of appropriate practice was from 45,70% to 80,92%. On average, each commune health station had 0,421 refrigeration; 0,128 ice cabinet; 0,258 cold box; 2,259 thermoses; 6,623 ice packs; 2,826 thermometers and11,321 safe boxes. All commune health stations have vaccine containing thermos; one station has no thermometer; two have no safe box and five have no ice pack. Conclusion: All commune health stations have essential instruments, cold chain. Very few health station lack of one or some types. Medical officers almost have basic knowledge about expandedimmunization, the rate of answering right theoretical questions from 61,64% to 94,55%. Practical manipulation had still many errors, rate of manipulation right only 45,70% to 80,92%. District officers manipulated right higher than commune officers.\r\n', u'

OBJECTIVEReal-time monitoring for temperature is required in cold chain for the medical products that are sensible with temperature, such as blood and bacterin, to guarantee the quality and reduce their wastage.

METHODSThis wireless monitoring system in cold chain is developed with Zigbee technology.

RESULTSFunctions such as real-time monitoring, analyzing, alarming are realized.

CONCLUSIONThe system boasts such characteristics as low power consumption, low cost, big capacity and high reliability, and could improve the capability of real-time monitoring and management in cold chain effectively.
