Claim 0:
1. A method of controlling blood loss during thrombus removal, the method comprising:
fluidically connecting a vacuum pump to a vacuum line and fluidically connecting the vacuum line to a receptacle for blood collection;
fluidically connecting the receptacle for blood collection to an aspiration tubing and fluidically connecting the aspiration tubing to an aspiration catheter;
positioning the aspiration catheter within the vascular system of a subject;
activating the vacuum pump;
introducing a vacuum pressure and a flow of air into the vacuum line;
introducing a vacuum pressure within the receptacle;
initiating a flow of blood through the aspiration tubing via the vacuum pressure within the receptacle;
collecting blood within the receptacle;
measuring a flow parameter of the blood within the aspiration tubing using a sensor;
receiving the flow parameter from the sensor at a vacuum controller;
comparing the flow parameter to a target range for the flow parameter;
sending an automatic control signal from the vacuum controller to a regulator based on a comparison of the flow parameter to the target range; and
adjusting the vacuum pressure and flow of air within the vacuum line according to information stored in the automatic control signal, thereby adjusting the vacuum pressure within the receptacle and the flow of blood through the aspiration tubing and the aspiration catheter.
