Background technique

Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia, which has become a worldwide public health problem that seriously threatens human health. There are 114 million patients in China, and about 30% of the patients need to monitor blood sugar and inject insulin. Diabetes is a chronic disease. In addition to being hospitalized, patients inject insulin at home most of the time. Each patient injects 1 to 4 times a day according to their own conditions. The insulin pen has the advantages of accurate injection dose, simple operation, convenient carrying and storage, etc. It is especially suitable for self-injection by diabetic patients at home. Because diabetic retinopathy and peripheral neuropathy are serious complications of diabetes, they can cause vision loss and sensory loss in the limbs. The survey results showed that 43.61% of the patients had the experience of being stabbed by discarded needles. One of the key issues in using insulin pen injections is the installation and removal of the needle for the insulin pen. At present, there is a lack of a practical and effective unloading aid for insulin pen needles in China. This situation leads to patients or their family members unloading the insulin pen needles with their bare hands. Because the insulin pen needles are small and sharp, it will inevitably cause sharp objects. risk of loss. The "Expert Consensus on Acupuncture Injury Prevention in China" published by the Chinese Nursing Association in 2018 clearly pointed out that during the use of various puncture needles, if the needle cap must be returned, an auxiliary tool should be used to return the needle cap with one hand. Based on this, it has become inevitable to develop a convenient and quick needle taker for insulin pen to avoid needle stick injuries to the greatest extent and escort the safety of insulin injection patients.
