Preferably, the puncture-proof structure is a cylindrical sleeve, and the wall of the sleeve is provided with at least one through hole.

Preferably, the junction of the sleeve and the blood transfusion spigot is provided with a notch.

The utility model provides a blood bag is prevented punctureing in leak protection, includes the bag body and blood transfusion socket, and the one end that blood transfusion socket is located the internal portion of bag is equipped with prevents stinging the structure, prevent stinging the structure and include two backplate, two backplate set up about blood transfusion socket's axle center is relative.

Preferably, the guard plate is arc-shaped, and the concave surface of the guard plate faces to the axis of the blood transfusion socket.

Preferably, the leakage-proof puncture-proof blood bag adopting any one of the technical schemes is adopted, and a leakage-proof structure for preventing blood from flowing out after the needle head is pulled out is further arranged inside the blood transfusion socket.

Preferably, the leakage-proof structure comprises at least three valves, the valves are made of elastic waterproof materials, and the valves are tightly attached to each other.

Preferably, a clamping mechanism for fixing the needle is arranged outside the blood transfusion socket.

Compared with the prior art, the leakage-proof puncture-proof blood bag adopting the technical scheme has the following beneficial effects:

firstly, adopt the utility model discloses a blood bag is prevented punctureing in leak protection, after the syringe needle inserts the back, the syringe needle is surrounded by the sleeve, and the sharp pointed end of syringe needle can't contact the bag body to avoid the bag integument to puncture.

The protective plates can support the bag body, so that the bag body is bent at a position far away from the blood transfusion socket, the tip of the inserted needle is positioned between the two protective plates, and the needle cannot contact the bag body, so that the bag body is prevented from being punctured.

Thirdly, because the valve has elasticity and waterproof, can outwards strut the valve when the syringe needle inserts, and when the syringe needle back of pulling out, a plurality of films reset and hug closely together because of the elastic action to sealed the blood transfusion socket, prevent that blood from spilling.

Fourthly, the clamping mechanism can keep the latch at the rear end of the needle head after the needle tube is inserted into the blood bag, so that the needle head is prevented from sliding off due to infirm fixation or external force.
