Infant incubator temperature calibration and measurement method

Abstract

The invention discloses a method for calibrating and measuring the temperature of an infant incubator. A first standard thermometer is set at point A, which is 10 cm above the center of the infant bed surface in the infant incubator, and a temperature measuring sensor is located at point B in the infant incubator. The second standard thermometer is set; the heating system of the baby incubator is closed, and the controller reads the measured value t1 of the temperature measuring sensor, the measured value TA1 of the first standard thermometer and the measured value of the second standard thermometer; the heating system of the baby incubator is turned on, The controller simultaneously reads the measured value t2 of the temperature measuring sensor, the measured value TA2 of the first standard thermometer, the measured value TB2 of the second standard thermometer and the heating power value P, and calculates the slope Kb and the temperature correction coefficient K of the temperature measuring sensor; In actual application measurement, the controller calculates the temperature representation value T at point B at any time Bn and the actual temperature value T at point A An and the output is displayed. The invention effectively improves the temperature measurement accuracy in the infant incubator.

Description

technical field [0001] The invention relates to hospital neonatal care equipment, in particular to a method for calibrating and measuring the temperature of an infant incubator. Background technique [0002] The baby incubator is a commonly used medical and nursing equipment in the neonatology department of the hospital. The accuracy of temperature measurement in the baby incubator is a very important technical indicator. The temperature measurement in the baby incubator belongs to "relative temperature measurement", that is, according to the national industry standard, the temperature of the baby incubator is 10cm above the center of the baby bed surface (indicated by point A), but in the actual measurement, due to the baby Limited by the special structure of the incubator and the existence of babies, the temperature measurement sensor cannot be placed in this position; therefore, when the baby incubator is working, the temperature measurement sensor can only be placed in o...

Problems solved by technology

[0004] At present, in accordance with the requirements of the GB standard, the baby incubators at home and abroad, at the two temperature points of 32°C and 36°C in the box, the difference between the measured value of the temperature at point B and the value measured by the standard thermometer at point A shall not be greater than 0.5°C , has been able to achieve; however, in the case of the entire temperature measurement range (20°C ~ 40°C) and the temperature outside the box (18°C ~ 26°C), the difference between the measured value of the temperature at point B and the value measured by the standard thermometer at point A The difference is often greater than 0.5°C, and even far exceeds the GB requirement of 0.8°C, so it cannot meet the health and care requirements of newborns
