Device for synchronously detecting blood sugar and injecting insulin

Abstract

The invention discloses a device for synchronously detecting blood sugar and injecting insulin. The device comprises a syringe, the syringe comprises a needle and a syringe tube with one end connectedto the needle, the front end of an inner cavity of the syringe tube is provided with a front piston including a front piston insert, the front piston insert is a check valve A from the rear to the front, the inner cavity at the other end of the syringe tube is provided with a rear piston, a rear cavity is formed between a rear piston and the front piston, the rear cavity is filled with the insulin, and the rear piston is connected with a piston driving device; a check valve B from the inside to the outside is disposed at the bottom of the front end of the inner cavity of the syringe tube, anda plasma blood sugar detecting device is disposed at the outer end of the check valve B. The device can perform blood sugar detection and insulin injection by one-time needling.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for synchronously detecting blood sugar and injecting insulin. Background technique [0002] At present, among the top 10 diabetes drugs in the world, there are 7 injectable insulin products, accounting for about 50% of the global diabetes drug market (Diabetes Atlas 8th Edition. Abu Dhabi: International Diabetes Federation; 2017.). There are about 39 million diabetics in China who need to rely on insulin to maintain blood sugar levels, and about 70% to 93% of these insulin users are using insulin pens (Global Report On Diabetes. Geneva: WorldHealth Organization; 2016.). [0003] For patients who use insulin pens to control blood sugar, most insulin pens need to be injected three times a day, and even long-acting insulin needs to be injected every day. However, most of the current insulin injection pens are of manual mechanical structure. The pressure rod of this type of ...

Problems solved by technology

The above-mentioned interstitial fluid blood glucose detection sensor has been widely used in many insulin pumps that require 24-hour blood glucose monitoring and insulin injection, but the plasma detection equipment still needs to be calibrated regularly (usually twice a day) during use, and patients need to purchase it separately Equipment calibration, especially for forgetful elderly users, often forget to calibrate, or simply forget to carry calibration equipment, which is very inconvenient
