Precautions for using syringe with needle
The business of syringe manufacturers originated from the large number of participants in the online advertising economy and chaotic supervision. The skin of the all-glass syringe in contact with the metal plate is cooled to 4.5 degrees Celsius (about 40 degrees Fahrenheit) to achieve the effect of paralyzing the skin. The main working principle is that ammonium nitrate dissolves in water and absorbs heat. When the cylindrical anesthesia machine was twisted, the membrane between the isolation areas ruptured and the ammonium nitrate reacted with water, causing the bottom metal plate to cool down rapidly.
The outer tube of the disposable indwelling needle is soft and can be bent with the shape of the blood vessel and placed in the blood vessel. It is not easy to pierce the blood vessel wall and cause liquid extravasation, which reduces the repeated puncture rate and reduces the patient's pain. Provides great convenience for patients. The product is fully enclosed, and the blood will not leak when a civilized person is working, which is convenient for medical personnel and civilized people to prevent infection. The product consists of catheter tubing, catheter seat, needle tube, needle seat, exhaust connector, bevel root, catheter assembly, protective cap, protective sleeve, etc.
