A liquid supply device for human insulin injection has a carrier on which a liquid storage chamber and a flow-guiding actuation unit are constructed, and a sensor and a driving chip are installed. The flow guiding actuation unit has a liquid guiding channel, which communicates with the liquid storage outlet of the liquid storage chamber and a liquid guiding outlet. The sensor touches the human skin to monitor the monitoring value of the blood sugar content in the sweat. The driving chip receives the monitoring value reading from the sensor, and controls the actuation of the diversion actuation unit accordingly, and controls the switching states of the valve switches of the liquid storage outlet and the liquid diversion outlet. After the flow-guiding actuation unit is driven, a pressure gradient is generated, so that the insulin liquid in the liquid storage chamber is output to the liquid-guiding outlet through the liquid-guiding channel, flows into the microneedle patch attached under the flow-guiding actuation unit, and passes through Its multiple hollow microneedles are injected into the subcutaneous tissue.
Description
【Technical field】 [0001] This case is about a liquid supply device, especially a liquid supply device for human insulin injection. 【Background technique】 [0002] At present, the treatment methods for type 1 diabetes and type 2 diabetes are mainly supplementary hypoglycemic drugs, and the administration methods include oral administration, syringe injection and insulin pump injection. Among them, oral and syringe injection methods, patients need to use blood glucose meters to test their own blood sugar levels every day, and then take medicine according to blood sugar levels. The insulin pump system consists of an indwelling needle and an insulin pump. The indwelling needle is placed in the body and fixed on the body surface for blood collection and drug injection. The insulin pump connected to the indwelling needle controls the release of hypoglycemic drugs according to the blood sugar level. [0003] Insulin can only be injected because it cannot be taken orally. Syringe ...
