Abstract:
Objective To design two-point two-line vein pricking for avoiding pain for patients and blood osmosis out of the vein caused by the high-pressure and fast-speed of the current high-pressure injector.Methods 19G butterfly-wing vein transfusion needle in the length of 19mm was used.The first point was needled with the needle tip under the skin and the first needling line was above and parallel the blood vessel in the length of 10-12mm.The second point was needled,with the second needle tip and needle line in the blood vessel,and the length of needling is 7-9mm.Results 100 persons were subjected.All the contrast medium and the physiologic saline were injected in vein in 98 persons,among which 2 had little hard tubercle in injecting area.Conclusion The two-point two-line vein pricking is safe for high pressure injector injecting in vein,and can prevent blood osmosis out of the vein.
