Traditional cotton swab disinfection is comparatively consuming time, and disinfectant is preserved inappropriately and is easy to lose efficacy and cause extravagant, and the disinfection effect of cotton swab butt joint side and cross section is not ideal etc. at present gradually fades out clinical use. The disposable alcohol cotton piece has the advantages of independent packaging, convenient carrying, good operation experience and the like, and is widely applied to clinic at present. The joint disinfection cap not only has the advantages of the disposable alcohol cotton piece, but also can provide a physical barrier for the infusion interface in the infusion gap, thereby reducing the related blood flow infection of the catheter and being popularized and used in clinic.

The existing disinfection cap is usually sealed by aluminum foil, but in the using process, because the disinfection cap is too small and has smooth appearance, in the process of tearing the aluminum foil by hands, the force is inconvenient, and the risk of sliding of the disinfection cap exists.
