Method and device for monitoring the infusion of an insulin pen

Abstract

The invention provides a method and a device for monitoring infusion of an insulin pen. The method integrates first detecting, second detecting and third detecting. The first detecting is used for detecting whether an infusion requirement unit is finished. The second detecting is used for detecting whether the infusion is unfinished in a timing mode or whether a motor continues infusion after normal time required by infusion. The third detecting is used for detecting whether motor and control data faults occur in real time in an infusion process. As long as any detecting is effectively, conditions requiring closing or stopping infusion can be detected timely, and the infusion can be closed or stopped timely so that infusion risks can be prevented better. In addition, implementation price of the monitoring method is low, and the method is easy to achieve and can be applied to various insulin pens in the market flexibly.

Description

technical field [0001] The present invention relates to methods and devices for monitoring the infusion of insulin pens. Background technique [0002] The incidence of diabetes is increasing day by day, and it has become the third biggest killer after cardiovascular and cerebrovascular diseases and tumors. At present, it is believed that insulin infusion therapy is an effective method for the treatment of diabetes. Intensive treatment through insulin infusion can make patients' blood sugar, blood lipid, blood pressure and BMI fully up to standard, and the high-precision infusion of electronic insulin infusion equipment is the best means of intensive insulin treatment. [0003] In the course of insulin infusion therapy, the accuracy of the infusion dose is very important. Insufficient dose will cause hyperglycemia and complications easily, while excessive dose will cause hypoglycemia or even coma or even death. Therefore, safe and accurate insulin infusion is of paramount i...

Problems solved by technology

[0006] For the current insulin infusion pen, in view of its low price positioning, the overall design idea is a mechanically driven structure, such as motor drive; moreover, simple and single monitoring is often used in its monitoring, such as only detecting infusion Whether the required unit is completed and then stop the infusion accordingly, or simply monitor whether the motor continues to turn after the infusion required unit has been completed. After the single monitoring fails, it will cause the wrong infusion of the insulin pen and thus affect the quality of the insulin pen. Threats to the health and even life of diabetic patients and at the same time the infusion process cannot be monitored "on-the-fly", i.e. the infusion cannot be interrupted in time in the event of an error in eg the control data controlling the infusion process
