Description

An anti-sticking device for indwelling needles on blood vessel walls

technical field

The utility model relates to the technical field of medical appliances, in particular to a fixing device for indwelling needles against sticking to blood vessel walls.

Background technique

Indwelling catheters are also called venous trocars. The core components include a soft catheter that can be indwelled in the blood vessel, and a stainless steel puncture guide core. When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter is completely inserted into the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy.
