August 23rd news: In daily life， everyone might have moments of foolishness， sometimes feeling too embarrassed to even recall them. Recently， a man in Jilin， Yanji， shared his experience online， sparking heated discussion.
It is reported that a man in Jilin， Yanji， who suffers from diabetes， needs to inject insulin regularly. To his astonishment， after a month of injections， he discovered that the needle cap had never been removed， rendering all the medication wasted. Upon realizing the truth， he was simultaneously amused and exasperated.
The man further explained that during his first week of injections， he went for a follow-up check-up. The doctor informed him that his blood sugar was still high. Consequently， he increased the dosage himself， only to find the medication squirting onto his abdomen.
Despite this， he did not realize where the problem lay. Initially， he assumed it was due to the larger dosage leaking out. This continued for a full month.
One day， while browsing videos， he noticed that his insulin injection process differed from others， leading him to understand that the needle cap had not been removed. Fortunately， he had been diligently controlling his diet and increasing his exercise over the past month， resulting in a significant drop in his blood sugar levels.
It is understood that insulin pen needles usually have two protective caps.
The outer cap is used to maintain the sterility of the needle and must be completely removed before use. It is often accompanied by an inner smaller cap (or safety cap). Some needle designs feature an inner cap that can be slid back after injection to prevent needlestick injuries. However， this inner cap must be removed before injection， otherwise， it will obstruct the flow of medication.
Patients who do not carefully read the instructions or do not receive guidance from medical professionals when first using the device may mistakenly believe that the inner needle cap is a protective structure that does not need to be removed， leading to the cap remaining on the needle during injection.
In fact， this incident is not an isolated case. According to data from the “Chinese Guidelines for Insulin Injection Techniques (2020 Edition)，” the error rate for insulin injection operations among diabetic patients in China exceeds 50%.
This highlights the critical importance of reading product instructions. However， in daily life， many people choose to disregard them altogether， leading to such humorous yet potentially serious blunders. While being laughed at might be a minor consequence， delaying proper treatment can have significant repercussions.
