Blood sugar monitoring and controlling system

Abstract

The invention relates to a blood sugar monitoring and controlling system, comprising a detecting device and a liquid supply device, wherein the detecting device can detect the blood sugar content of auser by detecting the tissue fluid of the user at any time; when the blood sugar content of the user is abnormal, the detecting device starts up the liquid supply device, so that the liquid supply device can immediately inject the insulin liquid into the body of the user, thereby adjusting the blood sugar level of the user, and enabling the blood sugar level of the user to be in a stable state for a long time.

Description

【Technical Field】 [0001] This case is about a blood glucose monitoring and control system, especially a blood glucose monitoring and control system that can monitor and control human blood glucose levels for a long time. 【Background technique】 [0002] Self-checking of blood glucose plays a very important role in the management of blood sugar for diabetic patients, but the current blood glucose meters used to measure blood glucose are not easy to carry, so it becomes difficult for patients to detect blood glucose levels when they are out, and during the process of measuring blood glucose, Sometimes there may be cases where the needle is punctured but there is no bleeding or the blood volume is too low. Therefore, it is necessary to puncture the needle again or squeeze out the blood forcefully. However, puncturing the needle again may burden the patient, and squeezing out the blood forcefully may cause inaccurate measurement results. In addition, when a patient finds that blood su...

Problems solved by technology

[0004] In order to solve the problem that the traditional insulin injection method will cause pain and inconvenience to the patient, this case provides a blood sugar monitoring and control system, including: a detection device, including a first microneedle patch, a liquid pumping actuator, and a sensor and a monitoring control chip, wherein the first microneedle patch has a plurality of hollow microneedles, attached to and inserted into the human skin to absorb a tissue fluid, the fluid-absorbing actuator is provided with a fluid-conducting channel and a first actuating unit, The fluid guiding channel communicates with the first microneedle patch, and the first actuating unit is actuated so that the fluid guiding channel forms a pressure difference to absorb the interstitial fluid, and also makes the fluid guiding channel absorb the tissue fluid produced by the plurality of hollow microneedles. The interstitial fluid is introduced, and the sensor is installed in the fluid guide channel to monitor the blood glucose content in the interstitial fluid, and transmit it to the monitoring control chip to interpret and calculate a blood glucose value information, and send a notification of the blood glucose value information; and A liquid supply device comprising a second microneedle patch, a liquid supply actuator, a liquid supply chamber and a liquid supply control chip, wherein the second microneedle patch has a plurality of hollow microneedles for attaching Inserted into human skin, the liquid supply actuator is provided with a liquid injection channel and a second actuating unit, the liquid injection channel communicates with the second microneedle patch, and communicates with the liquid supply chamber, and the liquid supply The chamber stores an insulin liquid, the second actuating unit is used to actuate and compress the liquid injection channel for liquid transmission, and the liquid supply control chip receives the notification of the blood sugar value information sent by the monitoring control chip of the detection device to activate the The second actuating unit of the liquid supply device makes the liquid injection channel form a pressure difference to transmit the insulin liquid stored in the liquid supply chamber, and guide it into the plurality of hollow microneedles to inject the insulin liquid into the subcutaneous tissue of the human body , in order to control the balance required for blood sugar
