Description

Needleless connector assembly with disinfection block

Technical Field

The utility model relates to the field of medical equipment, specifically be a needleless connector subassembly with disinfection block.

Background

In order to reduce the probability of puncture by the needle point; the risk that the rubber scraps flow into a human body due to the fact that a needle penetrates through the rubber plug for connection is avoided, the needleless connector is more and more widely used clinically, and particularly the needleless positive pressure connector with the positive pressure function is more widely used. The needle-free positive pressure joint can be connected with ports needing a heparin cap, such as a peripheral venous catheter, a central venous catheter, an indwelling needle and the like; the needle-free positive pressure connector can be connected with and lock the injector, the infusion apparatus and the blood transfusion apparatus for use. Before each treatment, the needle-free positive pressure connector end of the needle-free positive pressure connector needs to be strictly disinfected and wiped by using a disinfectant, and then the needle-free positive pressure connector can be used; after the treatment task is finished, the needle-free positive pressure connector of the needle-free positive pressure connector is exposed in the air, and is not protected in a sterile or relatively clean state, so that the infection is easily caused, and the needle-free positive pressure connector is not safe and inconvenient; before the treatment and use, medical care personnel need to spend a large amount of time to disinfect the positive pressure joint end, which wastes time and labor.

The needle-free joint of the current central venous catheter is exposed outside in the intermission period of transfusion, or is covered by gauze to protect the needle-free joint. Or with a sterilization cap that is disposable. However, this increases the workload of the nurse; while also increasing the risk of catheter-related bloodstream infections; as well as the cost of medical care to the patient.
