Description

Technical Field

[0001] The utility model relates to the technical field of extracorporeal oxygenation of blood, in particular to a perfusion bag dedicated to an extracorporeal cardiopulmonary auxiliary support system. Background Art

[0002] In some high-risk surgeries such as percutaneous coronary intervention (PCI), an extracorporeal cardiopulmonary support system is essential to maintain the patient's vital signs and organ function. Extracorporeal cardiopulmonary support systems replace damaged cardiopulmonary systems by providing artificial oxygenated blood and maintaining blood circulation. They are divided into heart assist devices and artificial ventilators, which can temporarily replace cardiopulmonary function, reduce surgical risks, prolong surgical time, and enable surgeons to perform surgery in a more stable condition, significantly improving the success rate of surgery.

[0003] The existing extracorporeal cardiopulmonary support system requires a complex and time-consuming priming process before use, as follows: (1) Select physiological saline or balanced salt solution containing heparin to fill the pipeline to prevent blood coagulation; (2) Carefully connect the pipeline to the ECMO machine and related equipment, and remove all air bubbles from the system to ensure that the pipeline is completely filled with liquid without gaps; (3) Push the priming liquid through the perfusion pump, while closely monitoring the flow rate and pressure to ensure that the entire system is evenly filled, which not only increases the difficulty of equipment preparation, but also prolongs the response time in emergency situations; and the above priming steps, including filling the loop system to prevent air embolism and ensure the continuous flow of blood in the system, are a technical challenge for the medical team and require delicate operation and monitoring. It increases the burden on medical staff and may also affect the timely treatment of critically ill patients. Utility Model Content

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] The power component and the oxygenation component are the two core components of the extracorporeal cardiopulmonary support system (ECMO). In layman's terms, the working principle of the extracorporeal cardiopulmonary support system is as follows: the power component draws venous blood from the human body (equivalent to heart function), the oxygenation component discharges carbon dioxide in the blood, and allows the blood to absorb oxygen (equivalent to lung function), and then returns the blood to the human body.
