Description

Blood glucose monitoring integrated device

technical field

Background technique

In recent years, the incidence of diabetes has been on the rise. Diabetics and pre-diabetics need to monitor blood sugar changes regularly in order to control life, exercise, diet and rational drug use; blood glucose meters are widely used in hospitals, families and other people who need to test blood sugar because of their small size, portability and accurate measurement. At present, the existing blood glucose monitoring devices all adopt the blood collection method of taking blood from the end of the human body for detection, which requires three parts: a blood glucose monitor, a blood glucose test strip, and a blood collection needle.

Among them, the existing blood glucose test paper is used in conjunction with the blood glucose monitor, which is coated with biological enzymes, which can test the presence of a certain glucose in the peripheral blood by reacting with glucose in the blood. The whole is in the form of a thin sheet; The needles are tapered and used to pierce the skin.

Among them, the working principle of the existing common blood glucose monitor is: glucose in the blood reacts with glucose oxidase and potassium ferricyanide fixed on the surface of the test strip to produce gluconic acid and potassium ferrocyanide. The blood glucose meter applies a constant working voltage to the test strip to oxidize potassium ferrocyanide to potassium ferricyanide to generate an oxidation current. The magnitude of the oxidation current is proportional to the glucose concentration. The blood glucose meter records the magnitude of the oxidation current and converts it to out the concentration of glucose.

When blood sugar needs to be monitored, it is necessary to take out the blood glucose test strip from the test strip box, insert the electrode part of the blood glucose test strip for electrical connection with the host of the blood glucose monitor into the socket on the blood glucose monitor and contact the electrodes of the host to transmit electrical signals, In addition, the blood collection needle is taken out to puncture the skin, and the blood is dropped onto the test area of the blood glucose test strip. After the blood glucose meter is processed by the processor in the host, the converted glucose concentration is displayed on the display screen.
