Description

PICC puts a tub hand mount

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a PICC (peripherally inserted central catheter) catheter placing hand fixing frame.

Background

PICC is an english abbreviation for peripherally inserted central venous catheter, which is inserted by a peripheral venipuncture in the front of the elbow, and travels along the blood vessel and finally reaches the superior vena cava. The PICC can be used for directly infusing the medicine into the central vein with high blood flow rate and large blood flow volume, so that the vascular damage of a patient caused by long-term infusion or infusion draft concentration and strong irritant medicine is avoided, the pain of the patient caused by repeated venipuncture is relieved, and the smooth treatment is ensured.

PICC puts a tub when disinfecting the puncture of arm puncture point, needs the patient cooperation to raise the arm of puncture, the upper limbs is unsettled to be shelved, carries out puncture in the puncture point puncture again after whole arm disinfection, nevertheless because of the patient lifts the arm by oneself and can't insist too long time, consequently needs the assistant to assist the patient to raise the arm, increases the human cost. The assistant station influences the operation of an operator, so that the operation is inconvenient; when the tube is placed, the arm of a patient can move or the placing position is not good, and the puncture device is easy to slide and cannot be fixed in position. The height adjustment and the angle adjustment of the conventional puncture support are inflexible, so that the hand position height or the angle of a patient cannot be put in place, the puncture position cannot be fully exposed, and an operator cannot grasp the puncture angle to cause puncture failure.
