Embodiment 1

[0044] figure 1 It is a schematic structural diagram of a simulation system for the blood flow distribution effect after VV-ECMO puncture provided in Embodiment 1 of the present invention. Such as figure 1 , the simulation system of blood flow distribution effect after VV-ECMO puncture includes:

[0045] Intravenous input pump 110 , fluid reservoir 120 , mannequin base 130 and cardiopulmonary bionic structure 140 arranged on mannequin base 130 . The cardiopulmonary bionic structure 140 is provided with two venous fluid input ports 1401, a pulmonary valve simulation device 1402, and a plurality of alternative puncture points 1403 corresponding to different puncture positions; The liquid pool 120 is connected to the pulmonary valve simulation device 1402; the cardiopulmonary bionic structure 130 is a hollow structure made of transparent materials to accommodate liquid; the intravenous input pump 110 is used to pump colorless liquid into the cardiopulmonary bionic structure 130...

Embodiment 2

[0061] Figure 2a It is a schematic structural diagram of a simulation system for the blood flow distribution effect after VV-ECMO puncture provided by the second embodiment of the present invention. Such as Figure 2a As shown, in this embodiment, the specific shape of the cardiopulmonary bionic structure is concretely described, and each candidate puncture point in the internal jugular vein model is drawn out to form multiple internal jugular vein intubation positions, and the puncture points in the femoral vein model are drawn out. Each alternative puncture point leads out to form multiple femoral vein cannulation positions.

[0062] In an optional implementation of this embodiment, a leak-proof structure may be provided on each alternative puncture point. Each leak-proof structure corresponds to a cannulation position of the internal jugular vein or a cannulation position of the femoral vein.

[0063] Among them, the function of the leak-proof structure is: to provide a...

Embodiment 3

[0089] image 3 It is an implementation flow chart of a simulation method for blood flow distribution effect after VV-ECMO puncture provided by Embodiment 3 of the present invention. Such as image 3 As shown, the method of the embodiment of the present invention specifically includes the following steps:

[0090] S310. Using the simulation system for blood flow distribution effect after VV-ECMO puncture according to the embodiment of the present invention, by adjusting at least one control variable, forming at least one observable blood oxygenation state after extracorporeal membrane oxygenation.

[0091] In this embodiment, the use of a disposable puncture to ensure the sealing of the venous line is taken as an example. First, the disposable puncture membrane is fixed at the cannula of the femoral vein and the internal jugular vein. After that, the venous input pump is connected to the water source and adjusted. Pressure, so that the simulated system of the blood flow dist...

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 ...
