Problems solved by technology
However, the traditional perfusion system will bring the particles generated when the transmission flexible shaft rotates into the blood, thereby polluting the patient's blood, prone to thrombosis and blood poisoning
At the same time, due to its precise structure and high speed of tens of thousands of revolutions, if a dynamic seal is placed at the far end of the perfusion system to prevent the perfusion fluid from entering the patient's body, the dynamic seal will be easily worn, and at the same time, the dynamic seal will be damaged. High temperature due to seal friction is generated at the seal, resulting in hemolysis and thrombus

The invention relates to a perfusion device and a blood pump comprising the same. The perfusion device comprises an inner pipe fitting that is provided with a first cavity and at least one second cavity distributed around the first cavity, wherein the second cavity is used for connecting with an infusion part, the first cavity is used for connecting with a liquid outlet part, and the first cavity communicates with the second cavity to form passages for dividing fluid flowing into the perfusion device into at least two parts, one part of the fluid flows out of the second cavity and is introduced into the body of a patient, and the other part of the fluid flows back to the first cavity and is led out to the liquid outlet part for in-vitro recovery from the patient. A blood pump comprises the perfusion device, a pump head device, a transmission device and a power output device. By means of the perfusion device, the hemolysis phenomenon generated by high-speed rotation of a transmission flexible shaft at the bearing can be reduced, thereby reducing number of particles into blood generated by friction between the inner pipe fitting and the transmission flexible shaft, and reducing blood pollution of the patient due to the particles entering the blood, thereby reducing the risk of blood poisoning.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a perfusion device and a blood pump comprising the device. Background technique [0002] Short-term transvalvular blood pumps are mainly used for first aid in cardiogenic shock and auxiliary circulation during high-risk PCI procedures. The short-term transvalvular blood pump placed on the aortic valve can provide flow support up to 4L / min, thereby replacing the pumping function of the heart, which can save the life of patients with cardiogenic shock, or stabilize the heart during surgery in high-risk PCI patients State, reduce the occurrence of arrhythmia, thereby reducing the risk of surgery, to ensure the success rate of high-risk PCI surgery. [0003] Transvalvular blood pumps require a perfusion system to lubricate and flush the bearings and drive shafts to avoid hemolysis and thrombus. However, the traditional perfusion system will bring the particles generated...
