AI Technical Summary

Technical Problem

Existing sterile injection needles can easily prick fingers during the re-coating process, causing psychological burden on medical staff and affecting operational efficiency and work quality.

Method used

A sterile injection needle was designed, which uses a sliding component and spring mechanism to ensure that the protective cap is securely fixed to the syringe after injection, preventing the hand from being pricked by the needle when retracting the cap. A rubber anti-slip pad and a finger ring limiting structure are used to improve operational stability.

Benefits of technology

This reduces the risk of medical staff getting pricked by needles when putting the protective cap back on, and improves the safety and efficiency of the operation.
