Title:
SECURITY NEEDLE SLEEVE OF VACCINE SYRINGE
Document Type and Number:
WIPO Patent Application WO/2023/155067
Kind Code:
A1
Abstract:
Provided is a security needle sleeve (1) of a vaccine syringe, comprising a protection end (11), an extension end (12), and a snapping part (13). The extension end (12) is arranged between the protection end (11) and the snapping part (13). The extension end (12) comprises an extension part (121) having the same outer diameter as the protection end (11) and spirally surrounding the protection end (11). The two ends of the extension part (121) are respectively connected to the protection end (11) and the snapping part (13). A destructible structure (14) is provided between an edge of the extension part (121) adjacent to a plurality of spiral structures formed by spirally surrounding the protection end (11) and an edge adjacent to the protection end (11) and the snapping part (13). By means of pushing the protection end (11) forward, the pushing force from the protection end (11) drives the destructible structure (14) to rotate and break up, such that the extension part (121) extends along with the forward movement of the protection end (11) and the protection end (11) sheathes the distal end of the needle of the vaccine syringe, thereby protecting the operators from being scratched or stabbed by the needle tip due to the exposure of the syringe needle tip.
