Description

A kind of hematology PICC anti-drop tube nursing device

technical field

The invention relates to the technical field of medical equipment, and in particular, to a PICC tube-drop prevention nursing device in the department of hematology.

Background technique

PICC anti-dropping catheter is a catheter inserted into the superior vena cava through the peripheral vein in front of the elbow. It can be used for a long time indwelling, and various drugs are directly delivered to the central vein, which can quickly dilute the drug concentration and avoid irritation. It can prevent the damage of blood vessels caused by sexual drugs, provide patients with medium to long-term intravenous infusion therapy, meet the needs of conventional treatment courses for cancer patients, reduce the pain caused by frequent venipuncture, avoid the damage of irritating drugs to the blood vessels of patients, and protect the blood vessels of patients. The patient's peripheral blood vessels, and the risk of PICC catheterization is lower than that of central venous catheterization, avoiding serious complications caused by neck and chest puncture, such as: pneumothorax, hemothorax, and the incidence of infection is reduced by 3% compared with CVC , to solve the problem of infusion in patients with poor peripheral vascular conditions.

The skin needs to be disinfected when nursing the PICC anti-shedding tube in the Department of Hematology. At present, tweezers are generally used to pick a cotton ball dipped in alcohol to wipe the skin. The alcohol cotton is made into the box and placed in the box. Although the box has a lid However, the cover needs to be opened when using, and sometimes the doctor forgets to cover it, so the alcohol cotton in the box is easily infected, especially when some patients cough or sneeze, which increases the risk of infection of the alcohol cotton in the box.
