METHOD OF MONITORING AN IMPELLER PUMP USED IN A MEDICAL APPLICATION |
| 摘要 |
The invention relates to a method of monitoring an impeller pump used in a medical application, wherein the structure-borne noise arising in the impeller pump is measured and this measured structure-borne noise is compared with a reference curve and/or with a limit value, wherein a signal is output as a sign for a disturbance of the operation of the impeller pump. The invention further relates to a blood treatment apparatus in which the aforesaid method is carried out. |

1. A method of monitoring an impeller pump used in a medical application by means of structure-borne noise analysis comprising the following steps:
measuring the structure-borne noise arising in the impeller pump; comparing the measured structure-borne noise of the impeller pump with a first reference curve and/or with a first limit value; concluding a disturbance of the operation of the impeller pump when the measured structure-borne noise of the impeller pump differs from the reference curve and/or exceeds the limit value; outputting a signal as a characteristic for a disturbance of the operation of the impeller pump. |
