Description

Needle ware is got to portable insulin for pen syringe needle

Technical Field

The invention relates to the technical field of insulin pen needle taking, in particular to a portable insulin pen needle taking device.

Background

Diabetes is a group of metabolic diseases characterized by hyperglycemia, diabetes is a chronic disease, patients are injected with insulin at home for most of time except for hospitalization, and each patient is injected 1-4 times per day according to self conditions. The insulin pen has the advantages of accurate injection dosage, simple operation, convenient carrying and storage and the like, and is particularly suitable for self-injection of diabetics at home. Since diabetic retinopathy and peripheral neuropathy are serious complications of diabetes mellitus and can cause visual deterioration and sensory deterioration of limb endings, investigation results show that 43.61% of patients have experienced pricking injuries by waste needles. One of the key problems in injection using insulin pens is the installation and removal of the insulin pen needle. At present, the practical and effective insulin pen needle unloading auxiliary tool is lacked domestically, the condition leads to the patient or the family members thereof to unload the insulin pen needle by hands, and the risk of sharp instrument loss is inevitably caused due to the fact that the insulin pen needle is small and sharp in entity. The research and development of a convenient and fast needle taking device for an insulin pen needle can avoid needle stick injury to the maximum extent, and is necessary for safe driving and protecting of insulin injection patients.
