Atrial pressure measurement equipment

Abstract

The invention relates to atrial pressure measurement equipment. The equipment comprises a strip-shaped catheter, a first sensor, a second sensor, a moving mechanism, a driver, an ultrasonic probe anda treatment device, wherein the strip-shaped catheter is used for introducing in the esophagus, and the moving mechanism, the driver and the ultrasonic probe are arranged in the strip-shaped catheter;the first sensor and the second sensor are arranged on the moving mechanism; pressure data is acquired through the first sensor and the second sensor, the wall thickness data of the esophagus and atrium can be acquired according to the ultrasonic probe, the data is processed through the processing device, the atrium pressure data is calculated, the moving mechanism can be pulled back into the strip-shaped catheter by the driver after measurement is completed, and the whole measurement process does not cause damage to the esophageal wall, and the aim of acquiring the atrial pressure in a non-invasive mode is achieved.

Description

technical field [0001] The present application relates to the technical field of heart pressure measurement, in particular to an atrial pressure measurement device. Background technique [0002] The damage of left atrial function is one of the early manifestations of many cardiovascular diseases. Left atrial pressure (LAP) is an important indicator in the process of left atrial filling, and it is an important indicator for various heart diseases, especially for evaluating left ventricular diastolic function. With the in-depth research on heart failure with preserved ejection fraction, left atrial pressure has been paid more and more attention. [0003] The traditional invasive method of obtaining left atrial pressure (LAP) clinically is to measure and evaluate left atrial pressure (LAP) by inserting a right heart catheter to measure pulmonary capillary wedge pressure. In addition, there are non-invasive methods such as transesophageal echocardiography, which has been used f...

Problems solved by technology

[0003] The traditional invasive way of obtaining left atrial pressure (LAP) clinically is to measure and evaluate left atrial pressure (LAP) by inserting a right heart catheter to measure pulmonary capillary wedge pressure. In addition, there are non-invasive methods such as transesophageal echocardiography, which has been used for a long time and is commonly used for non-invasive evaluation of cardiac dysfunction. , soft tissue to measure the periodic activities of the structures such as the heart wall, ventricle and valves below it, and display on the monitor as the relationship curve between the corresponding activities of each structure and time. This echocardiogram cannot characterize the left atrial pressure (LAP ), that is, the current non-invasive echocardiography is still unable to measure the left atrial pressure (LAP)
