Nurses are high-risk groups of needlestick injuries, and the incidence of blood-borne diseases caused by needlestick injuries is higher than that of other medical workers. Currently, needlestick injuries have become one of the major safety concerns of nursing staff. Surveys and studies have shown that needlestick injuries among nursing staff are related to a variety of risk factors, and they are concentrated in the process of disposal of sharps after use. Disposal of medical waste accounts for 16.8%, removal of venous needles accounts for 15.5%, and needle settling accounts for 10.7% , Arteriovenous blood sampling accounted for 5.7%. The 2018 Expert Consensus on Prevention of Needlestick Injuries pointed out that the use of appliances with safety devices can effectively avoid needlestick injuries and reduce the occupational exposure risk of nurses. Therefore, the development of new lancet products with protective functions is of great significance to prevent needle stick accidents and protect the health of medical staff.
