Continuous arterial manometry and ambulatory blood-gas analysis are often required for acute, critical, and critical patients in the perioperative surgical anesthesia and in the intensive care unit. Arterial puncture catheterization is often required. The radial artery is easy to touch, and fewer complications are caused after the catheter is placed, so that the radial artery is the preferred part of the arterial catheter. The current common arterial puncture catheter-placing needle is mostly a metal arterial needle core composite outer sleeve, and the arterial puncture catheter-placing needle comprises two steps: the first step is to penetrate the puncture needle core into the artery, and the second step is to put the outer sleeve into the artery. At present, after puncture is successfully performed at an angle of 30 degrees to 45 degrees, the puncture needle core is tried to be placed into the outer sleeve after blood return, if the placement of the outer sleeve is not smooth, the angle of the needle core is reduced to advance by 1-2mm, and then the outer sleeve is tried to be placed. Or the puncture needle core and the outer sleeve of the artery are directly penetrated into the artery by using a penetration method, the needle core is withdrawn, and the outer sleeve is slowly retracted until the blood returns smoothly and then is placed.
Disadvantages of the prior art: the outer sleeve is arranged outside the puncture needle core, and the distance between the head end of the outer sleeve and the head end of the puncture needle core is 2-3 mm, so that the phenomenon that the puncture needle core enters an artery to return blood in a visible way is often caused, but the outer sleeve is still arranged on the periphery of the artery, and at the moment, the outer sleeve is not easy to put in and pushes the artery open to cause arterial hematoma and arterial spasm, so that the puncture difficulty is further increased: firstly observing whether the puncture needle core enters an arterial vessel or not and whether blood returns or not, and then trying to place a sleeve, so that the tube placement is easy to fail; when the puncture needle punctures, a circular wound is formed on a blood vessel, a piece of blood vessel wall tissue which is circular is cut from the blood vessel wall, and when the blood vessel wall heals, the blood vessel wall needs to heal the circular wound.
