The metabolic process of the human body is a biological oxidation process, and the oxygen required in the metabolic process enters the human blood through the respiratory system, and combines with hemoglobin (Hb) in the red blood cells to form oxyhemoglobin (HbO₂), which is then transported to the human body. In the whole blood, the percentage of the HbO₂ capacity bound by oxygen to the total binding capacity is called the blood oxygen saturation SpO₂.

To explore the role of SpO₂ monitoring in screening and diagnosing neonatal congenital heart disease. According to the results of the National Pediatric Pathology Collaborative Group, SpO₂ monitoring is useful for early screening of children with congenital heart disease. High sensitivity is a safe, non-invasive, feasible and reasonable detection technology, which is worthy of promotion and use in clinical obstetrics.

At present, the monitoring of pulse SpO₂ has been widely used in clinical practice. SpO₂ has been used as a routine monitoring of the fifth vital sign in pediatrics. The SpO₂ of newborns can only be indicated as normal when they are above 95%, The detection of SpO₂ of newborn blood can help nurses discover the changes in children’s condition in time, and guide the basis for clinical oxygen therapy.

However, in neonatal SpO₂ monitoring, although it is considered to be a non-invasive monitoring, in clinical use, there are still cases of finger injury caused by continuous SpO₂ monitoring. In the analysis of 6 cases of SpO₂ monitoring In the data of finger skin injuries, the main reasons are summarized as follows:

1. The patient’s measurement site has poor perfusion and cannot take away the sensor temperature through normal blood circulation;

2. The measurement site is too thick; (for example, the soles of newborns whose feet are more than 3.5KG are too thick, which is not suitable wrapped foot measurement)

3. Failure to regularly check the probe and change the position.

Therefore, MedLinket developed an over-temperature protection SpO₂ sensor based on market demand. This sensor has a temperature sensor. After matching with a dedicated adapter cable and a monitor, it has a local over-temperature monitoring function. When the patient’s monitoring part skin temperature exceeds 41℃ , The sensor will stop working immediately. At the same time, the indicator light of the SpO₂ adapter cable emits red light, and the monitor emits an alarm sound, prompting medical staff to take timely measures to avoid burns. When the skin temperature of the patient’s monitoring site drops below 41°C, the probe will restart and continue to monitor SpO₂ data. Reduce the risk of burns and reduce the burden of regular inspections of medical staff.

Product advantages:

1. Over-temperature monitoring: There is a temperature sensor at the probe end. After matching with a dedicated adapter cable and monitor, it has a local over-temperature monitoring function, which reduces the risk of burns and reduces the burden of regular inspections of medical staff;

2. More comfortable to use: the space of the probe wrapping part is smaller, and the air permeability is good;

3. Efficient and convenient: V-shaped probe design, quick positioning of the monitoring position, connector handle design, easier connection;

4. Safety guarantee: good biocompatibility, no latex;
