Pulse-adjustable TAVR operation simulator

Abstract

The invention discloses a pulse-adjustable TAVR operation simulator which comprises a control box. An LCD display screen is arranged on the control box, the LCD display screen is connected with a control panel in the control box, an adjustable flow button, an adjustable frequency button and a power supply main switch are arranged on the control box, and the LCD display screen, the adjustable flow button and the adjustable frequency button are respectively connected with the 7V voltage power supply module, the 24V voltage power supply module and the UART interface end; the power main switch is connected with the main power supply module; the control panel is connected with a submersible pump which is connected with a simulated blood vessel pipeline in the water tank; when a frequency button of the LCD display screen is pressed down, the control panel sends a signal to the submersible pump, the submersible pump performs intermittent action, and when the submersible pump discharges water, the submersible pump penetrates through the aortic valve from the ventricle to reach the ascending aorta, the aortic valve is opened and the submersible pump sucks water, the pressure in the ventricle is reduced, the ascending aorta applies pressure to the aortic valve, and the aortic valve is closed; and a complete heart cycle is simulated. The simulator has the characteristics of high reliability, quick response, small size and easiness in assembly.

Description

technical field [0001] The invention belongs to the technical field of TAVR surgery simulators, in particular to pulse-adjustable TAVR surgery simulators. Background technique [0002] At present, the simulated TAVR surgical simulator used in China, in terms of providing a device for simulating heart frequency, the traditional device has high requirements for the linearity and starting voltage of the servo motor, and the cost is high; it needs to provide piston motion slide rails, and the overall volume It is too large and difficult to transport and carry; the simulator is composed of multiple connecting parts, which is cumbersome to disassemble and assemble, and many places need to be sealed, which may easily cause pressure instability; using a human body safety voltage higher than 36V is prone to safety accidents and other problems. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present inventi...
