Clinical workload overload, lack of experience, improper operating procedures, and the use of faulty needles are all common causes of needlestick injuries. Reasons for needlestick injuries caused by clinical needles include: (1) prolonged exposure of the needle, (2) needle length that is too long (approximately 3-5 cm), (3) the needle cover slipping off when the needle is being retracted with one hand, and (4) overfilled needle collection boxes. This device utilizes the design of angle, length, and space to not only accelerate the speed of drug withdrawal, but also provide needlestick protection for nurses during the medication preparation process.

Needlestick injury (NSI) is one of the important occupational injuries among healthcare workers worldwide, with nurses having the highest incidence rate. Healthcare workers are one of the most important human resources for medical care worldwide, but they also bear various risks in the complicated and busy care process. Clinical workload overload, lack of experience, improper operating procedures, and poor quality of needles can lead to nurses being accidentally stuck while extracting or disposing of drugs or needles. The reasons for clinical needlestick injuries are: (a) prolonged exposure time of bare needles, increasing the chance of contact; (b) needle length is too long (about 3-5 cm), making it difficult to grasp; (c) the needle cap slips off when the nurse removes it with one hand, and (d) the needle collection box is too full, increasing the risk of needle contact. This device uses angles, lengths, and spatial design to provide comprehensive needlestick protection for nurses during medication preparation, administration, and disposal, while also being operationally convenient. With a simple structure, the person extracting the drug can adjust the angle according to their own habits, reducing the time-consuming preparation process. It is also safe to use, as it does not require one-handed needle cap replacement, does not repeatedly contact the needle, reduces the number of times the needle is exposed, and can safely store the needle after preparation. It is also cost-effective, reduces the use of disposable materials, and has compatibility with various drug capacities and empty needles. It is also environmentally friendly, reducing the use of medical consumables and using single or simple packaging made by recyclable materials. In addition, we searched the global patent information retrieval system and found that the patents for safety needles focused on the safety structures of syringe needles, scalp needles, and venous indwelling needles, but did not have a design that combines the needle with storage space. Therefore, this innovation has advantages for global market markets.
