Portable automatic insulin injection device

Abstract

The invention discloses a portable automatic insulin injection device, which comprises a shell; the upper portion, close to the right side, of the shell is connected with an injection mechanism for insulin injection; the interior of the shell is connected with an adjusting mechanism for controlling the insulin injection amount; an insertion needle is fixedly connected with a movable sleeve through a connecting block; the outer wall of the movable sleeve is fixedly connected with a protective cover; one end, far away from the movable sleeve, of the protective cover is fixedly connected with a fixed sleeve; connecting rods are respectively connected between the movable sleeve and a mounting column and between the movable sleeve and the fixed sleeve; and a roller is rotatably mounted on the connecting rod where the mounting column is located through a fixing strip. According to the invention, the two rollers move towards the end close to the fixed sleeve while moving in the opposite directions, so that air at the end of a catheter is conveniently squeezed out, and a large amount of waste caused by squeezing out the air by discharging insulin is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a portable automatic insulin injection device. Background technique [0002] According to the International Diabetes Federation (IDF) statistics, the number of diabetic patients worldwide in 2011 reached 370 million, of which 80% were in developing countries. Clinically, a large number of diabetic patients are hospitalized in the non-endocrinology department of the hospital due to diabetic complications or other diseases. Among the diabetic patients admitted to the hospital, more intensive insulin therapy is used. However, non-endocrinology nurses have a slight lack of knowledge and skills in diabetes, which leads to some problems in diabetes treatment and care methods, and cannot perform professional diabetes treatment and care for patients. An existing portable automatic insulin injection device, in Before injection, the air inside the feeding tube must be expelled. In...

Problems solved by technology

[0003] The purpose of the present invention is to provide a portable automatic insulin injection device. When the two rollers move towards each other, they move toward the end close to the fixed sleeve, so that the air at the end of the catheter can be easily squeezed out, effectively avoiding insulin injection by discharging insulin. A lot of waste caused by squeezing out the air solves the problem of a lot of waste of insulin
