Abstract
Description
Technical Field

[0002] According to the requirements of IEC60601-1, the surface temperature of the applied part of the equipment that does not provide heat to the patient should not exceed 41°C. Special requirements are specified for the over-temperature of the applied part of the medical pulse oximeter. If the temperature between the blood oxygen sensor and the tissue contact surface exceeds 41°C, a series of special requirements need to be met. For example, c) under normal conditions and single fault conditions, when the initial temperature of the skin is 35°C, the maximum energy transmitted to the energized blood oxygen sensor in this mode should not be sufficient to generate a temperature exceeding 43°C between the blood oxygen sensor and the tissue contact surface.
[0003] For finger oximeters, the standard requires GB9706.261-2023 Clause 201.11 to measure the surface temperature of the pulse oximeter probe in contact with the patient's hand tissue. Currently, there are no similar products on the market. Generally, the experimenter uses his finger to simulate the patient's finger and measures the surface temperature of the blood sample probe contact surface. The temperature cannot be adjusted, and the test cycle of several hours is also a big challenge for the tester.
