AI Technical Summary

Technical Problem

Current technology cannot accurately locate the specific erroneous position of the interventional pump in the heart, and X-ray examinations can cause radiation hazards.

Method used

By acquiring flushing pressure data and adjusting the pump speed and flushing flow rate of the interventional pump, the incorrect location of the interventional pump in the heart can be identified.

Benefits of technology

It can accurately locate the erroneous position of the interventional pump without the need for radiographic examination, reducing radiation hazards, and does not rely on pressure sensors in the pump head assembly, keeping the interventional size small.

Abstract

本申请公开了一种介入泵的位置检测方法、装置、设备及血泵，属于人工心脏技术领域。所述方法包括：在检测到泵头组件在心脏内处于错误位置的情况下，获取冲洗液对应的冲洗压力数据；根据冲洗压力数据确定错误位置。本申请实施例提供的技术方案中，在检测到泵头组件在心脏内处于错误位置的情况下，通过获取能从泵头组件排出的冲洗液的冲洗压力数据，可以检测出泵头组件在心脏内所处的具体错误位置，术者无需对心脏部位进行射线检查即可知晓泵头组件的错误位置，减少了辐射对人体的危害。并且，该检测方法不依赖于在介入泵的泵头组件中设置压力传感器，泵头组件的介入尺寸可以保持在较小的范围。
