Description

Insulin injection pen

Technical Field

The utility model relates to the technical field of medical auxiliary instruments, in particular to an insulin injection pen.

Background

With the development of society, people change their living habits, work pressure is too great, diet structure is changed, and more people are replaced with diabetes. Insulin therapy is an important means of controlling hyperglycemia and has been widely used clinically, but the implementation of insulin therapy regimen depends on good injection tools and proper injection techniques. Diabetes requires daily insulin injections. The amount of insulin that needs to be injected per patient per day is not constant, and whether to take part in sports or take meals on time on the day can affect the amount that needs to be injected on the day, which is inconvenient. Many diabetics need to inject insulin all the year round, but insulin injection is a relatively complex process, and the patient needs to select the injection time according to the requirement, and the injection is usually performed in the early, middle and late three periods. And the injection sites are also different, for example, sites with more fat content: buttocks, hands, abdomen and thighs are common injection sites. When insulin is injected, the same part is not injected for a long time, otherwise local skin atrophy of human body is easy to cause, so the parts for injecting insulin are replaced in turn. Insulin is allowed to penetrate through the epidermal cells and into the subcutaneous tissue during injection. The fat content of different parts of the human body is different, the thickness of the epidermis is also inconsistent, but the length of the injection needle in the prior art is inconvenient to adjust, so that a patient needs to pinch the epidermis to ensure that the depth of the needle extending into is proper. Therefore, there is a problem in the prior art that the length of the insulin injection needle is inconvenient to adjust.

The existing insulin injection device has a single structure, only has an injection function, is disposable, needs to replace a needle tube and a needle frequently when the insulin injection device is used outdoors, is inconvenient to use, and is difficult to operate by a patient alone, and the needle is broken due to carelessness in operation.
