<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>

A healthy newborn infant acquired a substantial body burden of mercury by inhaling mercury vapor originating from a broken mercury expansion switch in the heating unit of an infant incubator. Highly toxic mercury vapor is produced in quantity by heating otherwise harmless metallic mercury. Switches and thermometers that contain mercury should be removed from infant incubators.

  Background: Heat-related illness during extreme weather events is a leading cause of death and morbidity among vulnerable populations. Heat health alert systems are crucial in preventing serious impacts due to extreme heat, however its efficacy is limited by available atmospheric temperature data. A study was conducted to determine the accuracy of a silicon band-gap sensor integrated into certain models of smartphones when compared to a well-documented thermistor themperature sensor. Methods: Ambient temperature readings were taken at a location chosen within Burnaby, BC, using both a Met One sensor and a Sensirion sensor integrated into a smartphone. The data was then analyzed using a dependent T-test for paired samples to determine whether there was a significant difference between the grouped readings. Results: According to the results of the dependent T-test with data adjusted to a calibration curve, it was determined that there was no difference between the readings taken by the Met One and the Sensirion sensors, t(30)= -0.68, p=0.5 (95% CI, -0.04 to 0.02). Conclusions: Although further research is needed, the results of this study suggest that temperature sensors found in smartphones may be a smaller, lower-cost, and more accessible alternative to some of the higher-end models currently used to measure ambient temperature for the purposes of public health planning and policy-making.

Heat flux measurement is used in the field of fluid mechanics and heat transfer to quantify the transfer of heat within systems. Several techniques are in common use, including: differential temperature sensors such as thermopile, layered resistance temperature devices or thermocouples and Gardon gauges; calorimetric methods involving a heat balance analysis and transient monitoring of a representative temperature, using, for example, thin-film temperature sensors or temperature sensitive liquid crystals; energy supply or removal methods using, for example, a heater to generate a thermal balance; and, finally, by measurement of mass transfer which can be linked to heat transfer using the analogy between the two. No one method is suitable to all applications because of the differing considerations of accuracy, sensitivity, size, cost and robustness. Recent developments including the widespread availability and application of thin-film deposition techniques for metals and ceramics, allied with advances in microtechnology, have expanded the range of devices available for heat flux measurement. This paper reviews the various types of heat flux sensors available, as well as unique designs for specific applications. Critical to the use of a heat flux measurement technique is accurate calibration. Use of unmatched materials disturbs the local heat flux and also the local convective boundary layer, producing a potential error that must be compensated for. The various techniques in common use for calibration are described. A guide to the appropriate selection of a heat flux measurement technique is provided according to the demands of response, sensitivity, temperature of operation, heat flux intensity, manufacturing constraints, commercial availability, cost, thermal disturbance and acceleration capability for vibrating, rotating and reciprocating applications.

AbstractStandardized methods and measures are ubiquitous in biomedical engineering and a key factor for the successful development and certification of novel biomaterials, implants or other medical devices. Hence, the development of standardized measurement techniques, which can be applied to nearly every material and device is of crucial importance. Within the current work, we introduce a method to evaluate the water permeability according to ISO/FDIS 7198. The setup was designed to determine the volumetric flow through a test sample for a given hydraulic pressure. One key feature is the effortless replacement of the chamber containing the test sample. The measurement technique can thus be applied to a variety of materials and medical devices. To demonstrate the functionality of the setup we fabricated nanofiber membranes using the process of electrospinning. Nonwovens with comparable thickness and varying morphology were analyzed with regard to water permeability. In particular the different fiber diameters as well as the modified inter-fiber distances result in large deviations of the water permeability. Furthermore, there are hints for a rearrangement of the nanofibers due to the applied hydraulic pressure. The developed measurement technique provides a powerful tool for the standardized quantification of the water permeability and can be applied to a variety of biomaterials and medical devices.
