Automatic monitoring system for central venous pressure

Abstract

The invention provides an automatic monitoring system for central venous pressure. The system comprises a three-way pipe, a pressure sensor connector, a pressure sensor, a signal transmission system and a record display system. The central venous pressure is acted upon the pressure sensor through effect of the pressure sensor connector. Then, the pressure sensor outputs an electric signal corresponding to central venous pressure. Then, central venous pressure is transmitted to record display system through the signal transmission system. Therefore, obtained data on central venous pressure can be used for clinical detection and analyses for doctors. The automatic monitoring system for central venous pressure has the following beneficial effects: there is no need to have complicated zero-positions to label so that central venous pressure can be rapidly measured in a real-time manner; through data transmission, central venous pressure can be used for real-time reception of clinical doctors and measurement of changes in central venous pressure and formulation of timely diagnosis and treatment schemes.

Description

technical field [0001] The invention relates to the technical field of sensors of medical instruments, in particular to an automatic central venous pressure monitoring system. Background technique [0002] Central venous pressure (CVP) is the pressure at the point where the superior and inferior vena cava enter the right atrium and is measured through a catheter placed in the superior and inferior vena cava or the right atrium. Central venous pressure measurement is the most commonly used technique in intensive care medicine and is of great significance for understanding effective circulating blood volume and cardiac function. Central venous cannula pressure measurement is often used to monitor cerebral perfusion pressure after dehydration, blood loss and hypovolemia, various types of severe shock, heart failure and low discharge syndrome, and craniocerebral diseases (such as brain tumors, cerebrovascular diseases, etc.). And cardiopulmonary bypass open heart surgery and ot...
