Description

Sleeve type PICC blockage dredger

Technical Field

The utility model relates to a PICC ductus venosus technical field specifically is a bushing type PICC blocks up dredge.

Background

The PICC venous catheter is a central venous catheter for peripheral venipuncture, and is characterized in that a catheter is used for puncturing veins of a peripheral arm, the catheter directly reaches a great vein close to the heart, so that chemotherapy drugs are prevented from being in direct contact with the veins of the arm, and the blood flow speed of the great vein is high, so that the chemotherapy drugs can be quickly diluted, and the stimulation of the drugs to blood vessels is prevented. Therefore, the upper limb vein can be effectively protected, the occurrence of phlebitis is reduced, the pain of the patient is relieved, and the life quality of the patient is improved.

If the PICC pipeline is blocked carelessly, 5000U/ml and 0.5ml of diluted urokinase can be injected into the PICC pipeline by using a negative pressure technology, the diluted urokinase stays for 15-20 minutes and is pumped back by using an injector, and blood is pumped out, so that successful thrombus fusion is indicated. If no blood is drawn, the above operation can be repeated repeatedly, so that the urokinase stays in the catheter for a certain time until blood is drawn. It should be noted that the total amount of urokinase should not exceed 15000 u. After the catheter was cleared, 5ml of blood was withdrawn to ensure that all medication and clot were withdrawn.

People often cause PICC ductus venosus's jam easily when using PICC ductus venosus to treat at present, and current PICC blocks up dredge structure reasonable inadequately, and the design is optimized inadequately.
