Can the disposable blood oxygen probe be charged?

01 Jan 1970

Disposable blood oxygen probe and degree probe work on fingers, toes, earlobes and newborn palms. Light-emitting diodes shine red and infrared light into these human tissues. Hemoglobin in human blood, tissues and bones absorb a lot of light in the monitoring section. The light passes through the end of the monitoring section, where a photosensitive detector on the side of the probe receives the light source. Disposable blood oxygen probe is an electronic equipment accessory that must be detected in clinical operations, general anesthesia and critically ill patients, newborns, children and other daily pathological treatments.


Hypoallergenic medical tape is an important physiological parameter reflecting the state of hemoglobin in the whole body. Continuous monitoring of oxygen saturation in critically ill patients allows early detection of hypoxia that may occur at any time. It can be used for clinical discussion and evaluation of blood oxygen saturation, to understand the body's aerobic function, to observe changes in the condition, and to avoid damage to the body caused by hypoxia. According to statistics, using blood chlorine monitoring alone can reduce anesthesia accidents by 40%, while using CO2 monitoring can reduce anesthesia accidents by 91%.

No matter what kind of anti-allergic tape, its sensor is composed of two light-emitting tubes and a photoelectric tube. One of the luminescent tubes emits visible red light with a wavelength of 660 nm, and the other luminescent tube emits invisible infrared light between 920 and 950 nm. The various probe elements do not differ much, but the connection method is slightly different. Its internal structure can generally be divided into three categories. The author divides it into alternating type, general positive type, and general negative type in his own language, and the structures represent Figure 2, Figure 3, and Figure 4, respectively. When the polarity connection method is different and the type of light is different, the reception and output of the signal are different. At present, the internal structure of the blood oxygen probe is roughly like this, and some of the probes have different resistance values at the joints, which can be used for probe connection and non-connection detection.
