Vascular bridging tissue perfusion system and perfusion method

Abstract

The invention discloses a vascular bridging tissue perfusion system and perfusion method. The system comprises a power source assembly, a fixing assembly and a temperature control assembly, the powersource assembly is connected with the fixing assembly through a pipeline, the fixing assembly is connected with the temperature control assembly through a pipeline, the temperature control assembly isconnected with the power source assembly through a pipeline, and a first compliance cavity assembly, a first pressure valve, a first flow sensor and a first pressure sensor are sequentially arrangedon the pipeline between the power source assembly and the fixing assembly; a second pressure sensor, a second flow sensor and a temperature sensor are sequentially arranged on a pipeline between the fixing assembly and the temperature control assembly; a second compliant cavity assembly and a second pressure valve are sequentially arranged on the pipeline between the temperature control assembly and the power source assembly; a Y-shaped interface pipe is arranged on the pipeline between the temperature sensor and the temperature control assembly; and the Y-shaped interface pipe is connected with a light stimulation assembly or an ion supply assembly. The system and method are beneficial to popularization and application.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a perfusion system and a perfusion method for grafted blood vessels. Background technique [0002] Coronary atherosclerotic heart disease, referred to as coronary heart disease, is a common and frequently-occurring disease with a high mortality rate. In recent years, the incidence rate in China has been increasing year by year, seriously threatening people's lives and health. Coronary artery bypass grafting, commonly known as coronary artery bypass grafting, is internationally recognized as the most effective method for treating coronary heart disease. When one or more coronary arteries are severely blocked or the blood supply is very insufficient, coronary artery bypass grafting should be performed to save the patient's life. [0003] Coronary artery bypass grafting is to establish a channel between the proximal and distal ends of the coronary artery stenosis, so that ...

AI Technical Summary

Problems solved by technology

However, in the current clinical practice, the protection of graft vessels still remains in the case of manual operation and empiricism, and it is difficult to summarize and quantify the indicators; therefore, there are very few clinical researches on the perfusion protection of graft vessels, and the research progress is slow; resulting in The reason for this state is that on the one hand, the perfusion method is imperfect, unclear, and still under exploration. On the other hand, it is also because the relevant research equipment and clinical equipment are not perfect, and there are no instruments and equipment for researchers and clinical Workers use, quantify indicators and verify effects

[0005] The current research is still at the complete extraction stage of the graft vessel, and there is almost no research and results on the perfusion protection of the graft vessel after implantation. The clinical method is to manually pressurize the graft vessel through a syringe, and the pressure is unstable. The speed is unstable and the single time is too short. It is estimated that the graft vessel needs about 30 minutes of inflation time before transplantation.
