The tansymeart system is a short-term left atrium-aortic type auxiliary device, and the working principle is that a catheter is placed in the left atrium through atrial septum puncture, and an axial flow pump pumps blood out of the left atrium and returns the blood to the aorta to achieve the effect of heart assistance. The extracorporeal membrane oxygenation (ECMO) is an extracorporeal life support technology, can replace cardiopulmonary function, provides stable circulating blood volume for cardiopulmonary failure patients, timely and effectively recovers blood supply and oxygen supply of important organs such as heart, brain and the like, and wins time and opportunity for the treatment of critical patients. The two systems are mainly connected with the blood vessel of the patient by utilizing the artery and vein cannula, venous blood of the patient is led out of the body, changed into arterial blood, and then sent into the arterial system of the patient through the artery cannula, so that stable circulating blood volume is provided for the tissue and organ of the patient with heart-lung failure.
Whether it is the TandemHeart or the ECMO, bubbles exist in the pipeline and the pump, on one hand, the bubbles can cause air lock to obstruct the flow of blood, and more serious, if the bubbles enter into the blood vessel of a human body, a large amount of blood foam can appear along with the blood flow entering into the heart, then the bubbles cause the volume to become large, the pulmonary artery and branches thereof are blocked, so that the blood can not enter into the lung, serious hypoxia and ischemia are caused, coronary artery can be blocked after entering into the coronary artery of the heart, serious cardiac dysfunction is caused, and finally acute heart failure can be caused to cause death. Therefore, the pump needs to use priming liquid to perfuse the pipeline, the pump and the oxygenator and discharge bubbles, and residual particles and disinfectant in the pipeline and Xu Beng before the pump is connected with the arteriovenous cannula, so that the micro-inflammatory reaction is reduced. In the prior art, the most commonly used method is to install a prefill bag filled with prefill liquid on an iron stand, then two pipelines extend downwards on the prefill bag and are connected with pipelines on two sides of a pump respectively, but the iron stand occupies a large space, and the installation of the prefill bag and the iron stand also consumes a certain time, which is unfavorable for the preoperative preparation condition of taking a minute and a second.

Detailed Description
The utility model is discussed in detail below in conjunction with the drawings and specific embodiments.
The quick sterile perfusion device of the extracorporeal circulation system comprises a base 11, wherein a perfusion liquid pool 12 is arranged at the top of the base 11, and a first socket 121 and a second socket 122 which are respectively connected with a liquid inlet pipe A and a liquid outlet pipe B at two sides of a pump C in an inserted mode are arranged on the pool wall of the perfusion liquid pool 12. When in use, the base 11 is directly placed on the operation table, and the pouring liquid pool 12 is at a certain height from the operation table, so that the pouring liquid pool can be poured rapidly and repeatedly by utilizing gravity. Compared with the prior art, the method does not need to arrange an iron stand or install and operate the pre-filling bag and the iron stand, so that manual operation steps can be reduced, the filling time is saved, and the exhaust efficiency is improved.
The rapid sterile filling of the tankem heart system is shown in fig. 3, the liquid inlet pipe a and the liquid outlet pipe B are respectively inserted into the first inserting opening 121 and the second inserting opening 122, and due to gravity, the filling liquid automatically enters the liquid inlet pipe a, the pump C and the liquid outlet pipe B from the first inserting opening 121, the pump C is restarted at the moment, the filling liquid enters the first inserting opening 121 and the second inserting opening 122 under the pumping action of the pump C and returns to the filling liquid pool 12, and in the process, bubbles in the liquid inlet pipe a, the liquid outlet pipe B and the pump C are discharged.
The rapid sterile filling of the ECMO system is shown in fig. 4, where the inlet pipe a and the outlet pipe B are inserted into the first insertion opening 121 and the second insertion opening 122, respectively, and due to gravity, the filling liquid automatically enters the inlet pipe a, the pump C, the oxygenator D and the outlet pipe B from the first insertion opening 121, at this time, the pump C is restarted, the filling liquid enters the first insertion opening 121 and the second insertion opening 122 under the pumping action of the pump C and returns to the filling liquid pool 12, and in the process, the bubbles in the inlet pipe a, the outlet pipe B, the pump C and the oxygenator D are discharged.
As a preferred embodiment of the present utility model, the first socket 121 is disposed on the wall of the pouring basin 12 near the bottom, where the pressure is also higher, and the gravity is added, so that the pouring liquid can easily and quickly enter the pipe of the tankem heart system/ECMO system for quick and clean air discharge; the second spigot 122 is provided on the wall of the casting pool 12 adjacent the bottom and the second spigot 122 is provided above the casting pool level where there is no liquid pressure so that the returning casting pool can also be easily and quickly returned to the casting pool 12.
