Technical Field

[0001] This utility model relates to the field of pulse oximeter technology, specifically a pulse oximeter probe performance testing device. Background Technology

[0002] A pulse oximeter is an instrument that measures the oxygen saturation in a person's blood. When the oxygen saturation drops, it indicates that there is a lack of oxygen in the body and that the body needs to replenish its oxygen saturation.

[0003] A pulse oximeter is an important medical instrument used to measure the oxygen saturation in human blood. When blood oxygen saturation drops, it indicates hypoxia in the body, requiring oxygen supplementation. To ensure the accuracy and reliability of pulse oximeters, performance testing of their probes is crucial. However, traditional testing methods often rely on manual simulation or direct testing on patients, which are not only inefficient but also potentially risky and inconvenient. Therefore, developing a device that can simulate real-world conditions and efficiently and accurately test the performance of pulse oximeter probes is of paramount importance. Utility Model Content
