The cavity between the left protective shell and the right protective shell is a sliding channel, and there is an arc-shaped bend protruding inward in the sliding channel, and the front ends of the left protective shell and the right protective shell are correspondingly provided with U-shaped openings.

When the utility model is used, the arc-shaped bend in the sliding channel can fix the utility model so that it will not slide along the venous needle hose and is convenient for infusion. After the infusion is completed, pull the venous needle out of the human vein and pull the In the utility model, the blade of the venous needle enters the slit between the left protective shell and the right protective shell along the U-shaped opening, and the needle tip of the venous needle completely enters the protective shell without the needle tip being exposed.

One side of the left protective shell is connected to the right protective shell, which is a foldable structure. Mounting holes are provided on the inner side of the left protective shell, and mounting posts are provided on the inner side of the right protective shell corresponding to the mounting holes.

The left protective shell and the right protective shell are of a split structure, the inner side of the left protective shell is provided with mounting holes, and the inner side of the right protective shell is provided with mounting columns corresponding to the mounting holes. The left protective shell and the right protective shell can be of a split structure, and are connected through mounting holes and mounting columns.

Grooves are provided on both sides of the connection between the left protective shell and the right protective shell, the first groove is set on the left protective shell, and the second groove is set on the right protective shell. The groove corresponds to the setting of the fins on the single-winged venous needle or the double-winged venous needle, and plays a positioning role.

Both the first groove and the second groove are rectangular. It is convenient to clamp the blade of the venous needle to prevent the needle of the venous needle from being moved and exposed, resulting in puncture injuries and cross-infection.

The length of the curved bend is 5 mm to 15 mm, and the effect of 10 mm is the best, which can well fix the utility model on the flexible tube of the venous needle without affecting normal infusion, and is convenient for infusion.

The anti-acupuncture protective cover for the venous needle is made of elastic plastic. The left protective shell and the right protective shell can be integrated or split, and the connection can be slit on one side. It is suitable for single-wing venous needles Slits on both sides are suitable for double-winged venous needles; due to the elastic material, the mating surfaces of the left protective shell and the right protective shell are seamlessly matched, and the blade of the venous needle can slide along the slits of the left protective shell and the right protective shell. The length from the first groove of the protective shell to the U-shaped mouth is slightly longer than the length of the venous needle. After the blade of the venous needle is locked by the groove, the needle of the venous needle is completely inserted into the protective shell, and the needle is not exposed to avoid needle tip injury and cross-infection.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model has a simple structure, and an arc-shaped bend is arranged in the protective shell, and the anti-acupuncture protective sleeve of the venous needle is convenient for infusion and not easy to slide when the venous needle anti-acupuncture protective cover is set on the venous needle hose; the protective shell is provided with a first groove and a second groove , can clamp the blade of the venous needle, prevent the needle tip of the venous needle from moving and exposing, avoid stab wounds and cross-infection, strengthen the prevention of infectious diseases, ensure the safety and health of medical staff and patients, reduce unnecessary medical disputes, and ensure safe intravenous infusion ;The end of the protective shell is provided with a U-shaped port, which is convenient for the blade of the venous needle to enter the mating surface of the left protective shell and the right protective shell.
