Technical Field
The utility model relates to the field of medical equipment, in particular to CVP chi school zero improvement device.
Background
Central Venous Pressure (CVP) refers to the pressure in the superior vena cava, inferior vena cava, and right atrium of the chest, and is one of the important hemodynamic monitoring items for patients.
The visual inspection method is commonly used clinically to judge whether the zero point of the scale and the 4 th intercostal of the axillary midline are on the same level, and the method has large error and takes time. The closed hydraulic sensing type measuring method with high accuracy is high in price of instruments, complex in instrument preparation, installation and debugging, high in operating specificity and difficult to master by beginners, and wide application of the closed hydraulic sensing type measuring method is limited. Factors that affect the accuracy of CVP include patient, operator and monitor factors, with a zero calibration factor of 26.25%.
In order to provide accurate monitoring data for clinical diagnosis and treatment, the negative effects of relevant factors should be minimized when monitoring CVP. The visual inspection method is commonly used clinically to judge whether the zero point of the scale and the 4 th intercostal of the axillary midline are on the same level, the method has large error, and the CVP needs to be re-calibrated when being measured again, and the error is large and troublesome.
