The invention discloses an automatic
hematoma flushing device which is specifically used by the following steps: 1) respectively connecting an infusion tube with a
balloon and a normal
saline infusion
bottle containing
urokinase, connecting the infusion tube at the lower end with a tee joint, and respectively connecting the other two ends of the tee joint with a negative pressure drainage
bottle and
hematoma to be flushed; (2) respectively fixing three valves on an infusion tube, fixing a
balloon, an eccentric wheel and the like together, and switching on a power supply of a control panel; in the rotating process of the eccentric wheel, continuously extruding the
balloon to change the volume of the balloon, so that the pressure periodically changes; (3) by changing the opening and closing conditions of the three valves, indicating the balloon filled with the flushing fluid flushes the
hematoma of the patient, after balance is achieved, carrying out negative pressure drainage and starting ratistathe next cycle when the drainage flushing fluid is almost too much. The invention has the advantages that periodic pressure is generated through rotation of the eccentric wheel, flushing liquid and hematoma are fully mixed, the hematoma is dissolved, dissolved liquid is drained out through the negative pressure drainage
bottle, and therefore the purpose of removing the hematoma is achieved. As the liquid in the infusion tube inserted into the hematoma flows all the time, blood coagulation can be avoided, the infusion tube is prevented from being blocked, and drainage failure is avoided. By means of the three electronic valves, closing and opening of the infusion tube are achieved, and the purpose of control is achieved.
