Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical infusion structures, in particular to a PICC infusion extension tube structure. Background Art
[0002] Disposable infusion extension tube is a common medical consumable. After sterile processing, it establishes a channel between the vein and the drug solution. It is suitable for pipeline connection, infusion, blood transfusion diversion, etc. It is generally composed of an inner cone Luer connector, an outer cone Luer connector, a main pipeline, a protective cap, and a protective sleeve. Some extension tubes also have flow stop clamps, tees, etc.; PICC refers to peripherally inserted central venous catheterization, which uses a catheter to puncture the vein of the peripheral arm. The catheter goes directly to the large vein close to the heart to avoid direct contact between chemotherapy drugs and the arm veins. In addition, the blood flow rate in the large veins is very fast, which can quickly dilute the chemotherapy drugs and prevent the drugs from irritating the blood vessels.
[0003] Deficiencies of existing technology:
[0004] The PICC catheters currently in use include single-lumen tubes, double-lumen tubes and triple-lumen tubes, among which single-lumen tubes are more commonly used. When a single-lumen PICC is used, the connector for connecting the syringe, the tube wing connected to the connector, and part of the infusion extension tube connected to the tube wing will be hung on the patient's arm. When the patient walks or swings his arm, the part of the single-lumen tube exposed outside the arm can be easily pulled and fall off, or when the arm swings, the connector and the tube wing will scratch the patient's skin.
