Intravenous infusion therapy refers to the treatment of infusion of fluids, medicines, nutritional support and blood transfusion through the intravenous route. It is a highly technical and professional treatment method. In the past, intravenous infusion therapy was only an additional treatment for critical diseases. Today, intravenous infusion has become an important means of treatment and support in medical care. According to statistics: in 1990, 81% of nurses spent 75% of their working hours on intravenous infusion therapy. Today, more than 80% of patients receive different forms of intravenous infusion during hospitalization, and treatment often continues until the end of treatment.

With the continuous expansion of intravenous infusion therapy, the risk of blood-borne infections caused by occupational exposure caused by acupuncture injuries to nursing staff is becoming more and more serious. Every year, about 200,000 nurses are injured by needles, and more than 20 blood infections are present. The hazards of source diseases. At the same time, as patient safety has become a public health issue of worldwide concern, the safety of nurses, which plays a key role in ensuring patient safety, has also been mentioned on the agenda.

Under the influence of the above-mentioned global environment, a new concept of intravenous infusion-needle-free infusion came into being. Needle-free infusion system refers to a type of device designed to repeatedly transport or withdraw liquid to the infusion line without needling. This system can realize one-way or two-way flow of liquid. The two-way flow of liquid allows users to add medicine or return Pump liquid. ——SFDA "Guidelines for the Technical Review of the Registration of Products for Single-Use Infusion Equipment" 2011

The needle-free infusion connector can avoid repeated puncture using needles and reduce the puncture wounds of medical staff; It has a positive pressure system to prevent blood from flowing back into the pipeline and causing blockage. It is best used with indwelling needles, PICC and CVC; it is easy to operate clinically. It is easy to use and can be connected to syringes, infusion sets, and blood transfusion sets; fully enclosed infusions reduce the chance of infection.

According to the statistics of the Chinese Nursing Society in 2013, the use of needle-free connectors and the acupuncture rate of related medical personnel has decreased by 50% since 2005. In 2009, the "Guidelines and Implementation Rules for Infusion Therapy Nursing" (INS) published by the People's Military Medical Publishing House advocated the use of needleless infusion connectors by medical institutions. At the same time, goals 5 and 9 of the "2009 Quality and Safety Objectives of Intravenous Therapy" promulgated by the Guangdong Provincial Department of Health advocate the use of needle-free infusion systems. Internationally, the 2011 US INS intravenous infusion therapy nursing practice standard emphasized needle-free infusion as a safety concept. According to statistics, in 2011, 97% of the hospitals in my country used heparin caps. The annual use of heparin caps is 332 million, and the needle-free infusion joints only have a share of 3%, and the annual use is less than 10 million. (The relevant data comes from the 2012 China Health Statistics Yearbook)

It can be seen from this that the usage rate of needleless infusion joints in my country is very low at this stage. Compared with heparin caps, needle-free infusion joints have an absolute advantage. With the improvement of the living standards of our residents, the continuous deepening of medical insurance work, and the continuous enhancement of residents' safety awareness, it is expected that the use rate of needleless infusion connectors in intravenous infusion therapy in my country will reach 50% in 2018. It is predicted that in 2018, my country's annual use of infusion joints will reach 647 million, and needle-free infusion joints will reach 324 million.
