Description

Technical Field

[0001] The utility model relates to the technical field related to insulin pens, in particular to an insulin pen for patients with visual impairment. Background Art

[0002] An insulin pen is a portable insulin injection device used to treat insulin injections in diabetic patients. It usually takes the form of an injection pen that looks like a pen, making it convenient for patients to carry and use. The insulin pen contains small capsules or syringes of insulin solution. Patients only need to adjust the dose and bring the injection head close to the skin and press a button to complete the insulin injection. Compared with traditional syringes, insulin pens are more convenient and accurate, reducing the pain and inconvenience of injections for patients. During use, it may be difficult for visually impaired patients to accurately locate the injection site because they find it difficult to clearly see the skin surface or the injection point. Therefore, there is a special need for an insulin pen for visually impaired patients.
