Intelligent injection device capable of being attached to skin to automatically inject insulin

Abstract

An intelligent injection device capable of being attached to the skin to automatically inject insulin comprises a machine shell, a medicine storage injection assembly, a telescopic injection needle assembly and a battery, the medicine storage injection assembly is installed on the right side in the machine shell, the telescopic injection needle assembly is vertically installed on the left side in the machine shell, and the battery is installed in the middle in the machine shell. The liquid outlet end of the medicine storage injection assembly is connected with the liquid inlet end of the telescopic injection needle assembly through the injection pipeline, the injection end of the telescopic injection needle assembly is located on the lower side, the injection end of the telescopic injection needle assembly stretches out and draws back up and down and is contained in the machine shell, and the battery is electrically connected with the medicine storage injection assembly and the telescopic injection needle assembly. The intelligent terminal is in signal connection with the medicine storage injection assembly and the telescopic injection needle assembly. The optimal injection force can be automatically adjusted and output according to seasons, environment temperatures and individual differences so as to achieve the most suitable injection depth, the depth of the steel needle pricking into the skin is automatically detected through the acceleration sensor, and the injection effect is judged.

Description

technical field [0001] The invention relates to the technical field of insulin injection, in particular to an intelligent injection device that can be applied to the skin to automatically inject insulin. Background technique [0002] The skin-facing insulin injection device (insulin pump) is a device that imitates the secretion method of insulin in the normal human body and infuses insulin into the unhealthy human body. During the insulin injection process, due to differences in regions, seasons, diets, and exercise, unhealthy people may become unhealthy. Different people absorb insulin differently, causing fluctuations in blood sugar. In addition, due to individual differences, the needle penetration depth of the insulin injection device will also be different, which will cause the contact part of the injection needle and the body tissue to be blocked, resulting in the failure of insulin injection, and in severe cases, life-threatening. [0003] Most of the existing insuli...

In addition, due to individual differences, the needle penetration depth of the insulin injection device will also be different, which will lead to blockage of the contact part between the injection needle and body tissue, resulting in failure of insulin injection, and in severe cases, life-threatening

[0003] Most of the existing insulin infusion devices do not establish a regression model based on seasonal, temperature and individual differences, and cannot automatically select the depth and strength of the needle injection, and the injection comfort is low
