Description

Technical Field

[0001] The present invention relates to the field of blood detection, and more particularly to a blood oxygen detection probe and a blood oxygen detection device. Background Art

[0002] Blood oxygen saturation (SpO2) is the percentage of oxygenated hemoglobin (HbO2) bound to oxygen in the blood to the total bindable hemoglobin (Hb) capacity, that is, the concentration of blood oxygen in the blood. It is an important physiological parameter of respiratory circulation and one of the important basic data in clinical medicine.

[0003] Blood oxygen saturation (SpO2) can accurately reflect the body's oxygenated hemoglobin status, evaluate the degree of oxygenation, understand the body's oxygen supply, and provide timely and accurate information for the diagnosis and treatment of diseases. Once an abnormality is found during monitoring, clinical intervention can be given in time to avoid serious consequences. Therefore, blood oxygen saturation monitoring has been widely used in life monitoring of critically ill patients. At present, finger clip and duckbill finger sleeve probes are mostly used for blood oxygen saturation detection. During the test, you only need to clamp the probe on the fingertips of the person, and the sensor inside the probe can detect the hemoglobin concentration and blood oxygen saturation of the human body.

[0004] During the monitoring process, whether the probe is fixed or not is also one of the contents that need to be paid attention to in clinical work. The most commonly used probe in clinical practice is the clip-on probe. Since critically ill patients are often accompanied by symptoms such as unconsciousness or irritability, it is easy for the probe to loosen, fall off, or even be damaged, which not only affects the monitoring results, but also increases the workload of clinical nursing work.

[0005] And because of the differences in height, weight, age, etc. of different patients, the thickness of their fingers is also different. In order to meet the needs of people with different finger thicknesses, manufacturers need to produce probes of different sizes, which makes the production cost high. During use, in places such as hospitals where probes are frequently used, in order to meet the needs of people with different finger thicknesses, it is necessary to prepare multiple probes of different sizes. For each patient, multiple attempts are required to select a probe of the appropriate size, which not only increases the cost of use for the hospital, but also brings great inconvenience to the patient.
