Insulin needle safety removal device

The present invention relates to a safety needle removal device, in particular to an insulin needle safety removal device. The design of the insulin needle safety removal device of the present invention allows the user to safely unload the needle without the hand being close to the needle. In addition to recycling, it is safe to apply needles and reduce the risk of needle sticking.

At present, the insulin pen needle has three types of long-acting drugs, quick-acting drugs, and mixed drugs according to the needs of patients. Each insulin drug contains 300u units/3ml of drug, and the injection content is adjusted according to the doctor's dose. The insulin needle is used with a sterile needle each time insulin is used. General operation step 1: tear the insulin needle protection piece and insert the needle into the insulin injection pen rubber soft plug. Step 2: Rotate the insulin pen and the needle. Step 3: Remove the needle cover and take it out, carefully remove the needle inner cover and discard it, and adjust the injection dose of the doctor. Step 4: Select the injection site, which can be injected into the abdomen, thighs, arms, and buttocks. Operation step 5: After the injection of the drug is completed, the needle is prepared to be removed, and the transparent outer cover is first combined with the injection needle, and the needle is most easily pinned at this time.

According to the survey, nearly 90% of medical staff in medical institutions have had a needle stick incident. Currently used syringes are divided into general type syringes and insulin pen injectors. The construction of the needle retrieval device for these two different types of syringes is completely different, and the medical staff must The needle is unloaded by the hand, causing the needle stick to accidentally occur.

Clinically, when the nursing staff recovers the pen-type syringe needle (such as the pen-type insulin needle), the needle stick still occupies a certain proportion, because the pen-type syringe needle is double-layered, the needle is short, and the hands are in close contact during use. The needle is prone to needle sticking hazards. Among them, the eyes of the elderly are degraded, the elderly hand is easy to shake or the blindness of the patient with blindness and diabetic retinopathy is often pinched when the transparent cover is covered; or the caregiver is easily accidentally pinned when the transparent cover is covered Therefore, the nursing staff is excluded from using the insulin needle, so that the nursing staff can choose to use the needle of the insulin syringe for taking the medicine to protect the patient, and prevent the two hands from returning the needle.

In view of this, the author of this creation is the result of years of experience in this business, which has led to the research engine. After continuous research and experimentation, Yan Mengsheng has improved a safe needle removal device for insulin needles. It is hoped that the improved insulin needle can be safely removed. The device design can make the elderly and medical staff easy to use and reduce the risk of needle sticking.
