Because of the absence of the automatically measuring settings, special medical person has to ward them. This aggravates the patient s mental burden and the nursing persons working burden. This also handicaps the synthesis management of the ward.
The system is developed to measure infusion liquid level and infusion speed. The system automatically transports the detecting signal to the nursing office. In it the infusing situation of every bed in every sickroom is displayed. When the infusion liquid level is under the given lower limit and the infusion speed is much faster or lower, the alarm will be made in nursing office and corresponding bed to remind the paramedic to deal with it, a variable- dielectric-constant capacitive sensor is designed. The experimental data is obtained with the use of electrodes of different width. By analyzing the correlation between them, it is found that the sensitivity affected by the speed of infusion. The model of the sensor is presented and then the
