Simulation cycle test system for ECMO (extracorporeal membrane oxygenation) and application of simulation cycle test system

Abstract

The invention relates to the technical field of in-vitro testing of medical instruments, in particular to a simulation cycle test system for ECMO (extracorporeal membrane oxygenation) and application of the simulation cycle test system. The invention provides the simulation cycle test system for ECMO. The simulation cycle test system comprises a pulmonary circulation simulation module, a flexible heart module, a systemic circulation simulation module, an ECMO detection module and a control detection module. The pulmonary circulation simulation module, the flexible heart module and the systemic circulation simulation module are used for simulating hemodynamic states of a human body under healthy and different pathological conditions. The control detection module is used for collecting data such as blood pressure, blood flow and oxyhemoglobin saturation and the like of each point in the test system, controlling the opening amplitude of each valve in the test system and simulating various cardiovascular and valvular diseases. A standardized ECMO testing environment is provided, a unified testing standard is provided for blood testing of ECMO and other interventional medical instruments, and meanwhile an effective basis is provided for ECMO clinical use risk assessment of patients with various valvular and cardiovascular diseases.

Description

technical field [0001] The invention relates to the technical field of in vitro testing of medical devices, in particular, the invention relates to a simulated cycle testing system for extracorporeal membrane oxygenation ECMO and its application. Background technique [0002] ECMO, namely Extracorporeal Membrane Oxygenation, is often used in the rescue of patients with cardiopulmonary failure. It can temporarily replace the patient's cardiopulmonary function, reduce the burden on the patient's cardiopulmonary, and can also buy more treatment time for medical staff. The working principle of ECMO is to extract deoxygenated blood from the patient's venous system, and after extracorporeal oxygenation, reinfuse it into the patient's body to maintain the patient's life. The core parts of ECMO are membrane lung and blood pump, which play the role of artificial lung and artificial heart respectively. [0003] During the research and development of ECMO, there are very high requirem...

AI Technical Summary

Problems solved by technology

At present, domestic ECMO is in the process of active research and development, but there is currently a lack of corresponding detection systems and evaluation indicators, and it is impossible to evaluate the feasibility, stability and safety of ECMO in the process of design, research and development, and experimentation, which is not conducive to product integration. objective evaluation

[0004] Before the use of ECMO, it is generally necessary to assess the risk of use of patients. At present, the risk assessment of the applicability of ECMO is mainly based on the experience of previous cases. For example, patients with aortic regurgitation or various heart diseases may have higher Large ECMO use risk, the judgment of risk level will affect the treatment of patients
