AI Technical Summary

Technical Problem

Existing interventional ventricular assist systems lack real-time detection and feedback mechanisms during perfusion, leading to potential risks such as excessive tubing pressure, blockages, leaks, and air ingress, which can affect surgical safety.

Method used

A pressure detection module monitors pipeline pressure in real time, a status judgment module identifies leakage or blockage, an auxiliary confirmation module guides disconnection and controls the infusion motor to adjust the venting process, and venting parameters are set according to the type of consumables.

Benefits of technology

It improves the safety and reliability of the injection guidance process, accurately identifies pipeline status, reduces false alarms, provides precise diagnostic information, ensures the efficiency and thoroughness of the venting process, and reduces risks.

Abstract

The application relates to a perfusion guide device, a method, a ventricular assist system, a storage medium and equipment for a ventricular assist device, which comprises a pressure detection module, a state judgment module and an auxiliary confirmation module, wherein the pressure detection module is used for detecting the pipeline pressure after at least one pipeline exhaust operation is completed, the state judgment module is used for comparing the detected pressure value with a preset threshold value to identify the leakage or blockage state of the pipeline, and the auxiliary confirmation module is used for instructing to disconnect the connection between the perfusion pump and the catheter pump when it is confirmed that the reason for excluding the pipeline blockage cannot be confirmed, and is also used for controlling the infusion motor to drive the perfusion pump to operate at a preset rotating speed for a preset auxiliary confirmation time period, and judging whether the blockage is located in the perfusion pump pipeline or the catheter pump pipeline based on whether the measured pressure value during the operation exceeds the preset threshold value.
