Fully-automatic mechanical insulin injection pump

Abstract

The invention discloses a fully-automatic mechanical insulin injection pump, which comprises a reformed mechanism of a mechanical watch, a continuously variable transmission of a belt friction wheel, an adjusting cam device of technical scheme, a gear rack precise injection and transmission mechanism, a dosage injection mechanism before meal, a medicine feeding system and the like. On the one hand, the output shaft of the mechanism drives the adjusting cam device of the technical scheme to further drive the continuously variable transmission of the belt friction wheel and the gear rack precise injection and transmission mechanism and finally drives the medicine feeding system to perform micro-injection of basic amount. On the other hand, a driven push rod on the cam device pushes a transmission belt on the continuously variable transmission of the belt friction wheel to change the axial position of the friction wheel so as to adjust the transmission ratio of the continuously variable transmission of the belt friction wheel. The fully-automatic mechanical insulin injection pump driven by fully-automatic mechanical way is environmentally friendly, safe and reliable, and can reduce the use cost. Therefore, the invention can vigorously accelerate the treatment effect of diabetes patients, alleviate the economic and spiritual pressure, improve the life quality and obtain good economic and social benefits.

Description

technical field [0001] The items described in the present invention belong to the technical field of household precision medical devices, and specifically relate to a portable, all-weather fully automatic mechanical insulin injection pump for treating type I and type II diabetes, especially for type II patients. Background technique [0002] When the normal pancreas secretes insulin, there are two secretion methods at the same time. One is the basal secretion of insulin. The pancreas will release insulin in small doses uninterrupted for 24 hours to maintain the basal blood sugar from rising. The second way of secretion is that after a meal, the pancreas will secrete a large amount of insulin in a short time to ensure that the food eaten will not cause a sudden increase in blood sugar. It is precisely because the pancreas of the human body has two secretory forms, basal and postprandial, that the blood sugar of normal people can be maintained at a normal level. [0003] The ...

Problems solved by technology

[0011] To sum up, on the one hand, the current insulin pump has a large market demand and a wide market development space, but because it is mainly concentrated in high-end technology monopoly and expensive, Chinese patients benefit less, and the price of imported insulin pumps is 40,000-40,000 yuan. 50,000 yuan, 20,000 to 30,000 yuan for domestic products. Adding the usual consumables, medicines and other expenses, it is undoubtedly an astronomical figure for most patients, so the purchasing power is not strong, and the popularity is not wide, so we can only take the next best thing , Oral drug therapy with large side effects has seriously affected the quality of life of patients, making patients unable to accept effective, safe and reliable treatment; Miniaturization and reliability have been greatly improved, but the price may be further increased, which further limits the use of groups
