Description

A fixed armband for a transducer for hemodynamic monitoring

technical field

The utility model relates to the field of medical equipment, in particular to a fixed arm band for a transducer for hemodynamic monitoring.

Background technique

Monitoring techniques such as invasive arterial blood pressure monitoring and transducer measurement of CVP are frequently used in clinical practice. Arterial blood pressure, CVP, and PICCO monitoring data are all important monitoring parameters that reflect the hemodynamic changes of patients. The accuracy of monitoring data has important clinical significance for the diagnosis and treatment of critically ill patients. Invasive arterial pressure monitoring mostly requires the use of a transducer to convert the pressure of the liquid into an electrical signal, and finally present it as a waveform on the display. The position of the transducer represents the reference level for pressure zero. When the patient requiring continuous pressure monitoring is in the supine position, the transducer needs to be placed at the level of the right atrium. In clinical practice, especially in ICU patients, in order to avoid ventilator-associated pneumonia, many patients cannot continue to lie on their backs, and the head of the bed needs to be too high to be greater than 30 degrees; or they need to turn over and change positions frequently to avoid hospital pressure sores. It has been reported in the literature that when the level of the zero position of the transducer changes, the systolic blood pressure, diastolic blood pressure, and mean arterial pressure will all change. For every 10cm increase in transducer height, the mean arterial pressure drop decreased by 1.5mmHg. How should the arterial pressure transducer sustain right atrial level? Currently, the commonly used fixation methods in clinical practice are to use pressure sensor bedside fixation rods or to fix the transducer on the bed sheet. These methods cannot keep the right atrium level as much as possible as the patient's body position changes. To ensure the accuracy of pressure monitoring, there is currently no uniform standard and answer in clinical practice.
