Abstract

The present invention relates to a safety catheter assembly. One aspect of the present invention provides a safety catheter assembly which comprises: a catheter having a tube; and a needle assembly, wherein the needle assembly comprises: a housing which is detachably coupled to the catheter; a handle member which is provided to be movable forward and backward within the housing; a needle which ismounted on the handle member; a fixing member for fixing the handle member to the housing in a forwardly moved position of the handle member when the handle member is forwardly moved such that the needle is exposed to the outside by passing through the catheter; and an elastic member for backwardly moving the handle member such that the needle is inserted into the housing when the handle member isreleased from the fixed state.

Description

technical field [0001] The present invention relates to a safety catheter assembly, more particularly, relates to a safety catheter assembly capable of compressing a local area of ​​a connector to prevent blood flow before connecting infusion, and the tube inserted in the blood vessel is not affected even if the infusion line moves. Background technique [0002] Generally, vascular catheters, such as intravenous catheters, are used to infuse fluids such as saline, various drugs, and parenteral nutrition to patients, or to draw blood from patients. [0003] The catheter assembly is intended to provide convenience by leaving the tubular connector on the patient so that the skin does not need to be repunctured when the drug solution is injected. [0004] Such catheter assemblies insert the tube into the patient with a separate guide needle to insert the tube into the patient and then remove only the guide needle. [0005] On the other hand, during the process of removing the g...
