Indication device used for indicating injection positions

Abstract

The invention discloses an indication device used for indicating the injection positions. The indication device comprises four coaxial concentric disc structures; the first disc structure and the fourth disc structure are fixed; the radius of the second disc structure is greater than that of the first disc structure; the radius of the third disc structure is equal to that of the fourth disc structure, and the radius of the third disc structure and the radius of the fourth disc structure are both greater than that of the second disc structure; the first disc structure and the second disc structure are divided from the middle and are respectively and correspondingly arranged as four quadrants to label different content; the content labeled on the second disc structure is located outside the circumference of the first disc structure; the third disc structure is evenly divided into seven parts which are correspondingly arranged as seven periods which are labeled respectively; the content labeled on the third disc structure is located outside the circumference of the second disc structure; the edge of the fourth disc structure is provided with an opening; the second disc structure is connected with the third disc structure in a mechanically meshed mode, and the second disc structure moves in a linkage mode when the third disc structure rotates. By the adoption of the indication device, the injection positions in different time periods can be determined, and injection efficiency is effectively improved.

Description

technical field [0001] The present invention relates to an indicating device for medical injection, in particular to an indicating device for indicating an injection position. Background technique [0002] With the gradual improvement of people's living standards and the continuous changes in the dietary structure of residents, the prevalence of diabetes in my country has shown a significant increase in the past 30 years. In 1980, the epidemiological data of 300,000 people in 14 provinces and cities nationwide showed that the prevalence of diabetes was 0.7%. From 2007 to 2008, organized by the Diabetes Society of the Chinese Medical Association, an epidemiological survey of diabetes was conducted in 14 provinces and cities across the country. The results showed that the prevalence of diabetes among adults over 20 years old in my country was 9.7%. [0003] The advent of insulin has completely improved the passive and embarrassing situation that diabetics rely on other method...

Problems solved by technology

However, for doctors and nurses who often shift shifts, it is difficult to clearly grasp the location of each injection for each patient due to the large number of patients and the location of each injection; for patients who inject themselves, due to their insufficient level Professional, so it is difficult to achieve accurate rotation of the injection position every time
