Technical Field
[0001] The utility model relates to the technical field of medical tools, in particular to a disposable pulse oxygen saturation sensor. Background Art
[0002] With the continuous development of modern electronic medical technology and related disciplines, medical monitoring equipment has become an indispensable part of medical electronic equipment, playing an increasingly important role in hospitals. The use of monitoring equipment not only reduces the workload of medical staff and improves nursing efficiency, but more importantly, it enables doctors to keep abreast of patients' conditions, enabling timely intervention in critical situations and improving the quality of care. Among the physiological parameters monitored, in addition to electrocardiogram (ECG) and blood pressure, the measurement of blood oxygen concentration (oxygen saturation) is also of great clinical significance. During surgical procedures or monitoring of critically ill patients, timely monitoring of blood oxygen levels is essential to prevent hypoxia.
[0003] Currently, in medical practice, it is difficult to promptly report changes in blood oxygen saturation and pulse rate. Furthermore, blood oxygen saturation in human blood is measured using a reusable blood oxygen saturation sensor with a fixed-size front end clamp that is used by adults, children, and infants. Because it is universal, it is very prone to loosening during the blood oxygen saturation measurement process, which has a greater impact on infants and young children. Flexible fixation is difficult to achieve, and the sensor is unstable, resulting in medical staff being unable to correctly judge the patient's vital signs.
[0004] To address the shortcomings of existing technologies, researchers have conducted extensive research and proposed various solutions. For example, a Chinese patent document [CN200910180675.8] discloses a pulse oximetry device with voice announcement functionality. The device includes a blood oxygen sensor and a host computer, characterized in that the host computer also includes a voice announcement circuit that announces the measurement results.
