Comparison of K-Type and T-Type Thermocouples for Stability and Uniformity of Infant Incubator Temperature Testing Based on Iec 60601-2-19

Abstract

<p>Infant incubator is one of the most important medical devices for newborn survival, especially preterm. However, aside from its benefits, some irregularities can be found on the devices that could lead to infant mortality, such as temperature deviations. The problem can be minimized by testing the infant incubator temperature parameter in accordance with IEC 60601-2-19 standard. However, there are various types of temperature sensors for related tests. Therefore K-Type and T-Type Thermocouples are compared in order to provide recommendations for infant incubator testing. The measurement technique used were referred to the instructions stated in IEC 60601-2-19 sub-clause Stability (with tolerance ±0.5<sup>o</sup>C) and sub-clause Uniformity (with tolerance ±0.8<sup>o</sup>C). For K-type thermocouples, the highest stability results at 32<sup>o</sup>C is -0.2<sup>o</sup>C and at 36<sup>o</sup>C is -0.4<sup>o</sup>C, while the highest uniformity results at 32<sup>o</sup>C is -0.1<sup>o</sup>C and at 36<sup>o</sup>C is -1.6<sup>o</sup>C, with the uncertainty of 1.7<sup>o</sup>C. For T-type thermocouples, the highest stability results at 32<sup>o</sup>C is 0.4<sup>o</sup>C and at 36<sup>o</sup>C is -0.4<sup>o</sup>C, while the highest uniformity results at 32<sup>o</sup>C is 0.7<sup>o</sup>C and at 36<sup>o</sup>C is 0.8<sup>o</sup>C, with the uncertainty of 0.3<sup>o</sup>C. The results of the independent t-test showed a different average, where the T-type thermocouples was higher than the K-type thermocouples. In other words, T-type thermocouples could be recommended for infant incubators testing.</p>

Advancement and Maintenance of Infant Incubator in Medokan Ayu Health Centre Surabaya for Effort to Kepp Continuity of Serive

“…During the counseling we conveyed that if the tool was to be used, it would be warmed up first for at least 15 minutes From TABLE 1 the value of the measurement results and the errors that occur all meet the requirements for the feasibility of the infant incubator tool. From TABLE 2 for the value of humidity, mattress temperature, humidity and noise at a temperature setting of 36 o C also meet the allowable threshold [26].…”

Performance Analysis of Water Heating System by Using Double Glazed Flat Plate Solar Water Heater

“…The thermal collector pipe used copper material with a diameter of 12.7 mm and a diameter of 15.7 mm. The temperature readings in this device used a HUATO S220-T8 thermocouple sensor and Dekko Corporation Korea Thermocouple sensor cable [23]. The steps of the research process can be seen in Figure 1 [24].…”
