Description

Technical Field

[0001] The utility model relates to the technical field of puncture catheters, in particular to a conveniently fixed puncture catheter. Background Art

[0002] PICC catheter generally refers to a central venous catheter inserted through a peripheral vein. It is a method of using a catheter to puncture the vein of the peripheral arm and directly reach the large vein near the heart to avoid direct contact between drugs and the arm vein. In addition, the blood flow rate in the large vein is very fast, which can quickly dilute the drug and prevent the drug from irritating the blood vessels. The indications for PICC mainly include the need for rapid infusion. It can also be used for patients who have difficulty in intravenous infusion. In addition, it can also be used for patients who require continuous deep vein administration or monitoring. Before inserting the catheter, it is necessary to observe the vascular distribution on both sides of the patient's upper arm and puncture through the basal vein or the middle cubital vein, usually under ultrasound guidance. And the PICC catheter needs to be cared for regularly to avoid infection.

[0003] The puncture catheter in the prior art needs to be fixed during use to prevent the catheter from falling off. However, the catheter in the prior art is fixed with tape, which has a poor fixing effect and easily causes the catheter to fall off. Therefore, improvements are needed to address the above problem.
