In recent years, patients suffering from metabolic disorders such as diabetes, hyperlipidemia, and hyperuricemia continue to increase, and the treatment of such diseases requires medical assistance in addition to self-controlled diet-enhancing exercise. However, the administration of such drugs requires real-time adjustment according to their own real-time status. Taking diabetes as an example, the most obvious physical abnormality index of a diabetic patient is blood sugar concentration, and the blood sugar concentration in blood needs to be detected in real time during treatment, and the dosage is determined. If the measurement is not carried out, the situation of inaccurate dosage exists, the excessive dosage can cause the patient to be syncoped or even suddenly killed due to hypoglycemia, and the insufficient dosage can not achieve good treatment effect. Therefore, in the treatment of diseases such as diabetes, it is necessary to detect the concentration of a specific component in blood in real time.

At present, the real-time monitoring of indexes such as blood sugar and the like mostly adopts tip blood sampling, namely fingertip blood, and the tip blood sampling is simple in operation and low in cost, so that a patient can measure the indexes at home without going back and forth to a hospital. At the same time, peripheral blood sampling has a series of drawbacks. The diabetics have the defects of high blood sugar concentration, high viscosity and insufficient fluidity, and the fingers can heal rapidly after the blood taking needle is punctured during blood taking, so that the blood taking quantity is insufficient and even no bleeding occurs. The traditional mode is to squeeze the fingers to accelerate the blood to flow out, and the mode can smoothly obtain enough blood samples, but the operation is complicated, the squeezing can bring additional pain to a patient, and the tissue fluid is easy to squeeze out due to improper operation to influence the measurement result.
