Temperature calibration and measurement method of baby incubators

Abstract

The present invention discloses a temperature calibration and measurement method of baby incubators. The method comprises the steps: setting a first standard thermometer at a position A 10 cm above acenter of a baby bed surface in a baby incubator and setting a second standard thermometer at a position B of a temperature measurement sensor in the baby incubator; closing a heating system of the baby incubator and simultaneously reading a measurement value t1 of the temperature measurement sensor, a measurement value TA1 of the first standard thermometer and a measurement value of the second standard thermometer by a controller; starting the heating system of the baby incubator, simultaneously reading a measurement value t2 of the temperature measurement sensor, a measurement value TA2 of the first standard thermometer, a measurement value TB2 of the second standard thermometer and a heating power value P by the controller, and calculating a slope Kb and a temperature correction coefficient K of the temperature measurement sensor; and in actual application measurement, calculating a B point temperature representation value TBn and an A point actual temperature value TAn at any moment by the controller and conducting outputting and displaying. The temperature calibration and measurement method effectively improves temperature measurement precision in the baby 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
