Split-type piezoelectric-driven intelligent insulin patch

Abstract

The invention discloses a split-type piezoelectric-driven intelligent insulin patch. The intelligent insulin patch comprises a program control unit, a wireless transmission module, a piezoelectric micropump, a liquid level detection device, a patch type bottom frame, an embedded needle and a medicine storage box; the wireless transmission module is fixed on the program control unit, and the program control unit, the piezoelectric micropump and the liquid level detection device are fixed on the patch type bottom frame; the embedded needle is fixed at one end of the patch type bottom frame; the medicine storage box is hung on the patch type bottom frame; a medicine storage tube is arranged in the medicine storage box; the medicine storage tube is in pipeline connection with the embedded needle through the piezoelectric micropump; and the program control unit is electrically connected with the wireless transmission module, the piezoelectric micropump and the liquid level detection device. The upper cover of the medicine storage tube and the upper cover of the medicine storage box are transparent, so that the device can calibrate the bursting dose through the liquid level detection device, the piezoelectric micropump and vision, and compared with the prior art, the split type piezoelectric driven intelligent insulin patch has the advantages that the piezoelectric micropump is small in size, high in infusion precision, good in stability and lighter and thinner in appearance.

Description

technical field [0001] The invention belongs to the technical field of media input into the human body or into the human body, and in particular relates to a split-type piezoelectric-driven intelligent insulin patch. Background technique [0002] Diabetes is a group of metabolic diseases characterized by hyperglycemia. Hyperglycemia is caused by defective insulin secretion or impaired biological action, or both. At present, it has become the third chronic disease that seriously threatens human health after cardiovascular and cerebrovascular diseases and tumors in my country. During the treatment of diabetes, continuous subcutaneous insulin injection, that is, insulin pump therapy, is still the best choice for the treatment of diabetes. Accurate and quantitative subcutaneous infusion of insulin simulates the physiological secretion mode of insulin in healthy people, that is, the secretion of the basal rate, thereby regulating the blood sugar content of the patient's body to...

Problems solved by technology

[0003] The vast majority of insulin pumps that have been disclosed so far are driven by motors and threaded transmission for drug injection. This driving and transmission method is limited by the screw pitch and motor, and the structure is complicated. The volume of insulin pumps is relatively large, and it is difficult to miniaturize. The replacement is troublesome, the replacement cycle is short, and the cost is high
