Abstract

The invention relates to the field of blood pressure devices, in particular to a hydraulic analog device for an invasive blood pressure test. The hydraulic analog device comprises a master control processing module, wherein a blood pressure analog module is connected to the master control processing module, a signal feedback module is further connected between the blood pressure analog module and the master control processing module, the master control processing module is used for controlling the blood pressure analog module to conduct blood pressure state analog, and the signal feedback module is used for feeding back the blood pressure state. According to the hydraulic analog device, the pressure in a hydraulic analog cavity is changed constantly, so that dynamic blood pressure analog is completed; information which is fed back is compared with information detected by an invasive blood pressure detection device, so that the accuracy of the invasive blood pressure detection device is detected; by means of hydraulic analog of invasive blood pressure, the accuracy of invasive blood pressure analog can be effectively improved, true analog of the invasive blood pressure state can be realized, and the accuracy of the invasive blood pressure detection device can be detected accurately; during research and development of the invasive blood pressure detection device, the accuracy of invasive blood pressure detection conducted by the device can be monitored at any time, and therefore the research and development efficiency of the invasive blood pressure detection device is improved.

Description

technical field [0001] The invention relates to the field of blood pressure devices, in particular to a hydraulic simulation device for invasive blood pressure testing. Background technique [0002] Blood pressure is an important parameter used to monitor the blood circulation status of the human body. An important physiological parameter of the function of the human body circulatory system. Its accurate measurement, especially long-term accurate detection, is indispensable in clinical medicine and medical care, especially for the monitoring of critically ill patients and patients under general anesthesia. Clinical blood pressure technology can be divided into direct method and indirect method, namely non-invasive blood pressure measurement and invasive blood pressure measurement. Non-invasive blood pressure measurement is a measurement method widely used at present. Its advantages are convenient measurement and no harm to the human body. However, non-invasive blood pressu...
