AI Technical Summary
The current balloon dilation device used in interventional therapy has a cumbersome pressurization and depressurization operation, and the pressure output is unstable, which can easily lead to vascular damage.
The system employs an electrically driven delivery mechanism, pressure sensor, pressure relief valve, and main unit to achieve automatic pressurization and real-time pressure monitoring of the balloon. It sets thresholds to control pressure relief and, combined with a buffer pressure stabilizing chamber and alarm device, ensures pressure stability and safety.
It reduces the operator's workload, provides stable fluid flow and pressure control, avoids vascular damage, and improves the uniformity and safety of balloon dilation.

Abstract
Claims
1. An interventional balloon dilation device, characterized by, include; A delivery mechanism for delivering medication to a balloon to achieve pressurization, the delivery mechanism including a delivery line (1) and a pump body (2) disposed on the delivery line (1) and electrically driven. Pressure sensor (3), the pressure sensor (3) is installed on the delivery pipeline (1) at the output end of the pump body (2) and is used to monitor the fluid pressure in the delivery pipeline (1) in real time; Pressure relief valve (4) is installed in the delivery pipeline (1) at the output end of the pump body (2), and can relieve pressure in the delivery pipeline (1) when it is opened; The main unit (5) is electrically connected to the pressure sensor (3) and the pressure relief valve (4) respectively.
