Patch type medicine infusion system

Abstract

The invention discloses a patch type medicine infusion system which comprises an infusion structure, and the infusion structure comprises a medicine storage cylinder used for containing medicine to be infused and provided with a medicine inlet and a medicine outlet; one end of the infusion needle is communicated with the medicine outlet of the medicine storage cylinder, and the other end of the infusion needle is conveyed to the subcutaneous part to achieve medicine infusion; the control structure is connected with the infusion structure to control medicine infusion; the infusion structure and / or the control structure can be pasted on the surface of the skin through the sticky patch; to-be-infused medicine is injected into the medicine storage cylinder through the medicine inlet, the volume of the injection structure is deliberately set to be larger than that of the to-be-infused medicine, air in a medicine pipeline can be pumped out through negative pressure generated by redundant space in the injection structure, the risk that the air is infused into the body is reduced, and potential safety hazards are reduced; and user experience is improved.

Description

technical field [0001] The invention mainly relates to the field of medical devices, in particular to a patch type drug infusion system and a drug filling method thereof. Background technique [0002] The pancreas in a normal human body can automatically monitor the glucose level in the human blood and secrete the required insulin / glucagon automatically. In diabetic patients, the pancreas does not function properly and cannot secrete insulin normally. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function of the human body, and it is also listed as one of the three major chronic diseases by the World Health Organization. At present, medical technology cannot cure diabetes, and the occurrence and development of diabetes and its complications can only be controlled by stabilizing blood sugar. [0003] A diabetic patient using an insulin pump needs to pre-infuse insulin into the infusion structure and check blood sugar before injecting insulin into ...

AI Technical Summary

Problems solved by technology

[0004] However, there is air in the drug pipeline of the current infusion structure when it leaves the factory, and there is no exhaust during the drug infusion process, thus increasing the risk of air being infused into the body and causing safety hazards
