Abstract

A cardiac output automatic measuring system includes a cardiac output measuring device (2), a liquid injection device (3) and a main control device (1). The cardiac output measuring device (2) can be in a signal connection with a temperature sensor at the front end of a floating catheter, cold liquid can be injected to the floating catheter by the liquid injection device (3), and the main control device (1) is in a control connection with the liquid injection device (3). In measurement, the liquid injection device (3) is controlled to start and inject cold liquid according to a set injecting parameter by the main control device (1) and blood temperature is detected through the temperature sensor and the cardiac output is measured by the cardiac output measuring device (2). The uniformity of the liquid injection is ensured by the liquid injection device (3), the accuracy and consistency of the result of the cardiac output measurement are guaranteed, and thus accurate data can be provided to medical personnel.

Description

technical field

[0001] The invention relates to a cardiac output measurement system, in particular to a cardiac output measurement system using thermodilution method. Background technique

[0002] The method widely used clinically to monitor cardiac output is the thermodilution method. The thermodilution method is to insert a floating catheter into the pulmonary artery through the right atrium, and then inject cold saline into the right atrium through the catheter. A temperature sensor is placed at the front end of the catheter. When the cold saline is mixed with blood, the temperature changes. When the blood enters the pulmonary artery, it will be sensed by the temperature sensor, and the cardiac output will be analyzed according to the moment when the cold saline is injected and the temperature change after mixing.

[0003] When the thermodilution method is used, since the blood and cold saline are mixed in the right atrium, the temperature change of the mixed blood and c...
