The utility model relates to a ruhr joint protective cap, in particular to a ruhr joint protective cap with disinfection function.

Background technology in the process of intravenous infusion, blood transfusion, intravascular angiography and so on, luer connector is used as the connecting device. In clinical use, the Ruhr connector used for transfusion, blood transfusion and intravascular angiography is often used many times to input different kinds of drugs into the human blood circulation system. However, the existing ruhr joint is usually not equipped with a protective cap. When the ruhr joint is not connected, it will be exposed to the air, so it is easy to pollute the ruhr joint.

summary of the invention

The technical problem to be solved by the utility model is to overcome the above shortcomings of the prior art and provide a ruhr joint protective cap which can be sheathed on the ruhr joint, so that the ruhr joint will not be polluted due to being exposed to the air when it is not connected, and the ruhr joint protective cap also has the function of sterilizing the ruhr joint.

The technical scheme adopted by the utility model is a ruhr joint protective cap, which is used together with the ruhr joint. The utility model is characterized in that the ruhr joint protective cap comprises a cap body and a disinfection plug adsorbed with volatile disinfectant; The cap body is provided with a cavity which is opened at the bottom of the cap body; The disinfection plug is arranged in the cavity; The lower end of the cap body is provided with a thread interface matched with the ruhr joint.

The inner wall of the cavity close to the disinfection plug is provided with a ring protrusion, and the disinfection plug is composed of sponge.

The outer surface of the cap body of the ruhr joint protective cap is provided with a plurality of vertical bumps for anti-skid.

The ruhr joint protective cap further comprises an outer packing box, which is composed of a top cover and a cylinder containing the ruhr joint protective cap, the top cover covers the mouth of the cylinder, and comprises a cover part matched with the shape of the mouth of the cylinder and a long strip handle part, and the cover part is connected with the cylinder in a tearing sealing way.

After adopting the above technical scheme, as long as the ruhr joint protective cap of the utility model is rotationally sheathed on the ruhr joint, the pollution of the ruhr joint due to exposure to the air can be avoided. Meanwhile, the volatile disinfectant in the ruhr joint protective cap volatilizes, and the bacteria and other microorganisms in the ruhr joint can be killed, so as to play the disinfection function. The utility model has the advantages of simple structure and convenient use.
