Description

Technical Field

[0001] The utility model relates to the technical field of indwelling needles, in particular to an indwelling needle protection device. Background Art

[0002] An intravenous catheter, also known as an intravenous cannula, is a soft catheter that can be placed in a blood vessel, and a stainless steel puncture guide needle core. Because the intravenous catheter can be left in place for many days, the patient does not need to be re-punctured during infusion, which can greatly reduce the patient's pain. Therefore, intravenous catheters are widely used in clinical practice. However, intravenous catheters have the following disadvantages during daily use: 1. Patients are prone to pressing or pulling on the needle tip of the intravenous catheter in daily life, which brings inconvenience to the patient's daily movements; 2. In current life, most people use elastic bandages to wrap the intravenous catheter for protection. This fixation method can easily cause poor blood circulation in patients, making the skin permeability of the puncture site poor. Utility Model Content
