Insulin pump

Abstract

The insulin pump of the present invention relates to a portable electronic controlling insulin injection device, which can inject the insulin to the human body under a certain time and certain quantity. The present invention is helpful for keeping stable blood sugar for the diabetes patients. The present invention can be widely used in the 1 type diabetic patients, 2 type diabetic patients and the diabetic patients with pregnancy. The structure comprises the insulin pump body, the transparent medicine store cabin, the medicine store device, the medicine injection piston, the medicine injection pushing rod, the battery cabin, the battery, the digital display, the motor, the reducer, the motor seat and a joint of the medicine transportation. A medicine store cabin is arranged in one side of the insulin pump body. A transparent observation window is arranged outside the medicine store cabin. The medicine store tool is inserted in the medicine store cabin. A motor cabin is arranged in the back part of the medicine store cabin. The motor is arranged in the motor cabin. The reducer is connected with the motor directly. The output shaft of the reducer is provided with the thread. The hollow medicine injecting rod is provided with an inner thread. The one end of the injection rod is provided with the outer thread. The medicine injection rod sleeve is arranged outside the motor and the reducer.

Description

technical field [0001] The insulin pump of the present invention relates to a portable electronically controlled insulin injection device that can regularly and quantitatively inject insulin into the human body, which can help diabetic patients maintain stable blood sugar throughout the day, and is widely used in type 1, type 2, special type and pregnancy type diabetic patients. Background technique [0002] At present, there are two main methods for the treatment and control of diabetes: one is conventional treatment, that is, insulin injections 1-2 times a day and blood glucose monitoring 1-2 times a day; Monitor and adjust diet and insulin dosage to keep blood sugar as close to normal as possible. This method is mostly achieved by using an insulin pump. [0003] In 1993, the Diabetes Control and Complications Trial DCCT conducted the largest long-term clinical trial using the above two methods to observe the benefits of intensive glycemic control. The results of the stu...

Problems solved by technology

[0004] After insulin pumps were formally used in clinical practice, brushless DC motor insulin pumps appeared successively; composed of control system, power system, and delivery device, they automatically and quantitatively deliver insulin to the human body multiple times within 24 hours; Dual 16-bit CPU control mode, adopting the deceleration motor with feedback as the semi-closed-loop control system of insulin pumps; but these products do not have the safety guarantee of the dual-CPU mutual inspection system, and there is no closed-loop blood glucose detection port reserved. There are certain limitations in the use security and expansion performance of the product
