Abstract

The invention discloses a system and method for simulating the blood flow distribution effect after VV-ECMO puncture. The simulation system comprises a vein input pump, a liquid storage tank, a human body model seat and a cardiopulmonary bionic structure arranged on the human body model seat. The cardiopulmonary bionic structure is a hollow structure made of a transparent material and is used for accommodating liquid; the vein input pump is used for pumping colorless liquid into the cardiopulmonary bionic structure so as to simulate blood circulation of a human body; and when the artificial heart-lung machine is connected with two target puncture points in the alternative puncture points, colored liquid is pumped into the heart-lung bionic structure, and the observable blood oxygenation state after extracorporeal membrane lung oxygenation is formed. According to the technical scheme, the simulation system capable of observing the blood flow distribution effect after VV-ECMO puncture is creatively provided, and quantitative evaluation on the blood flow distribution effect after VV-ECMO puncture is conducted in different modes is achieved.

Description

technical field

[0001] The invention relates to the technical field of medical auxiliary teaching, in particular to a simulation system and a simulation method for the blood flow distribution effect after VV-ECMO puncture. Background technique

[0002] ECMO (Extracorporeal Membrane Oxygenation, Extracorporeal Membrane Oxygenation) refers to the life support technology that draws blood from the body, oxygenates it through an artificial oxygenator (also known as "membrane lung"), and then reinfuses it back into the body. A form of life support. ECMO equipment, also known as an artificial heart-lung machine, is mainly composed of an artificial oxygenator, a drive pump, an artificial pipeline, and intubation of blood vessels in the body, which can fully or partially replace the heart pumping and lung ventilation functions to maintain the patient's overall The oxygen supply and hemodynamics of tissues and organs are relatively stable, which ensures the circulation and perfusion ...
