Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to ECMO pipeline is towards valve in advance.
Background
In vitro membrane oxygenation (ECMO), membrane lung for short, is an expansion and extension of the range of extracorporeal Circulation (CPB) technology, which can be used for effective respiratory circulation support of critically ill patients with respiratory and/or circulatory insufficiency requiring external assistance, which was derived from extracorporeal circulation of cardiac surgery, and was used in 1975 for the treatment of severe respiratory failure in newborns, in 1980, the first ECMO center was established under the lead of Bartlett physicians from the american medical center, and subsequently 145 ECMO centers were established in succession around the world, and since nearly 10 years, with the advent of new medical approaches, the ECMO technology has been greatly improved, and the application range has been expanded more than before.
The essence of ECMO is an improved artificial heart-lung machine, the most central parts being the membrane lung and the blood pump, which function as artificial lung and artificial heart, respectively. In ECMO operation, blood is drawn from the vein and passes through the membrane lungs to absorb oxygen and remove carbon dioxide. The blood, after gas exchange, can be returned to the vein (VV access) and also to the artery (VA access) under the push of the pump. The former is mainly used for external respiration support, and the latter can be used for external respiration support and cardiac support because the blood pump can replace the blood pumping function of the heart. When the patient's lung function is severely impaired and ineffective for routine treatment, ECMO can assume the role of gas exchange, leaving the lungs in a resting state, gaining valuable time for the patient's recovery. And when the cardiac function of the patient is seriously damaged, the blood pump can replace the cardiac pumping function to maintain the blood circulation.
But present ECMO pipeline and puncture pipe connection are through beating normal saline (avoiding the air admission) while bare-handed connection simultaneously, and this the pipe that leads to bare-handed connecting line increases the infection chance easily, and can't reach 100% carminative purpose and the cost of labor that needs the operation is bigger (need 4 people at least to operate), in order to solve these problems, need use a neotype ECMO pipeline preflush valve urgently.
