Vascular access monitoring device |
摘要 |
A vascular access monitoring device for monitoring characteristics of a skin piercing vascular access device comprising: an acoustic sensor operable to detect an acoustic emission created by flow through said vascular access device and produce an electrical signal indicative of said emission; electronics processing means for processing and monitoring said electrical signal, and to determine, by identifying a change of characteristic of said signal, the possibility that the vascular access device has become dislodged from its normal working position. |

1. A vascular access monitoring device fbr monitoring characteristics of a skin piercing vascular access device, the monitoring device comprising:
an acoustic sensor operable to detect an acoustic emission created by flow through said vascular access device and produce an electrical signal indicative of said emission; and an electronic monitor that monitors said electrical signal and processes it to determine, by identifying a change of characteristic of said signal, the possibility that the vascular access device has become dislodged from its normal working position; wherein the electronic monitor comprises an electrical input that, in use, receives a signal from an extracorporeal blood pump; and wherein said extracorporeal blood pump is arranged for intermittent pumping and the electronic monitor receives a signal indicative of a pumping cycle of said extracorporeal blood pump. |
