10. A method for using a waste liquid collecting device for intensive care, which is applied to the waste liquid collecting device for intensive care according to any one of claims 1 to 9, characterized by comprising the steps of,

the method comprises the following steps that firstly, a suction pump 13 is started, the suction pump 13 is communicated with a liquid suction gun (11) through a T-shaped three-way ball valve (6), an L-shaped water pipe 7 and a liquid suction pipe 8, nursing staff hold the liquid suction gun (11) by hands in the process of nursing the patients with the severe symptoms to collect waste liquid generated by the patients with the severe symptoms, the waste liquid flows through the liquid suction gun (11) along the liquid suction pipe (8) and then enters a purification barrel (3), the purification mechanism carries out filtration treatment on the waste liquid, and the filtered waste liquid flows into a water storage tank (12) to be collected;

step two, after the waste liquid generated by the critically ill patient is collected, the nursing staff puts the liquid suction pipe (8) in the placing disc (9), inserts the liquid suction gun (11) into the insertion hole (10), and adjusts the T-shaped three-way ball valve (6) to enable the L-shaped water pipe 7 and the storage barrel 4 to be in a communicated state;

step three, starting a water pump (5), pumping the cleaning liquid in the storage barrel 4 by the water pump (5) through a pipeline, flowing through a T-shaped three-way ball valve (6) and then flowing into a liquid suction pipe (8), cleaning the inner wall of the liquid suction pipe (8), starting an extrusion mechanism in the cleaning process, and intermittently extruding the liquid suction pipe 8 which is coiled on a placing plate (9) by the extrusion mechanism;

and step four, cleaning the surface of the liquid suction gun (11) polluted by the waste liquid generated by the ill patient through a cleaning mechanism, and enabling the cleaned water to flow into the purification barrel (3) for purification treatment and then flow into the purification barrel (3) for purification treatment.
