Precautions for the use of syringes

The skin that the all glass syringe contacts with the metal plate is cooled to 4.5 degrees Celsius (about 40 degrees Fahrenheit), so as to achieve the effect of paralyzing the skin. Its main working principle is that ammonium nitrate dissolves in water to absorb heat. When the cylindrical anesthesia apparatus is twisted, the film between the isolation areas is broken, and ammonium nitrate reacts with water, resulting in the rapid cooling of the bottom metal plate.

The all glass syringe is retained in the patient's artery through the cannula in a short time. It does not need to puncture the human body repeatedly during multiple infusion, which greatly reduces the patient's pain and reduces the medical risk. The continuous development of society promotes the continuous development of medicine and other aspects. The use of indwelling needle is also known as trocar.

The outer tube of the 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 puncture the blood vessel wall and cause liquid extravasation, which reduces the repeated puncture rate and reduces the pain of patients. It provides great convenience for patients. The product is fully enclosed, and the blood will not leak out when working in a civilized manner, which is convenient for medical staff to work in a civilized manner and reduce infection. The product is composed of catheter pipeline, catheter base, needle tube, needle base, exhaust joint, slope root, catheter assembly, protective cap, protective sleeve, etc.

During multiple infusion, there is no need to puncture the human body repeatedly, which greatly reduces the patient's pain and reduces the medical risk.
