When the device is used, the drainage tube 2 and the tube head 3 are inserted into the position of effusion of a patient, the drainage tube and the tube head are bonded and fixed outside, the negative pressure pump 9 is started, the negative pressure pump 9 enables the inside of the collection box 1 to form a negative pressure state, and the effusion is extracted by utilizing the negative pressure. The negative pressure pump 9 works stably, and when the effusion is extracted in a stable state, the negative pressure state in the collecting box 1 is also stable. The middle part of the annular elastic air bag 4 is a drainage inlet. When the drainage import was blockked up by coagulum etc., caused the hindrance of hydrops extraction, then the inside negative pressure of collecting box 1 risees, and atmospheric pressure sensor module 15 detectable lasts the decline to the short-term of atmospheric pressure, and the treater judges that the drainage import is blockked up this moment, and treater control driving motor 13 work realizes pulsed negative pressure work, avoids blockking up.

As shown in fig. 2-4, in the pulse type negative pressure working state, the processor controls the driving motor 13 to start, drives the cam 14 to rotate, and rapidly and repeatedly extrudes and releases the sealed air bag 12, when the sealed air bag 12 is extruded, the sealed volume is reduced, the negative pressure in the collecting box 1 is reduced, the air pressure is increased, the control air bag 6 is compressed, the control air bag 6 is directly communicated with the elastic air bag 4, the elastic air bag 4 is expanded, the diameter of the inlet is reduced, at the moment, the elastic air bag 4 extrudes and compresses the coagulated blocks blocked at the inlet of the end part, the sealed air bag 12 is released rapidly, the sealed air bag 12 expands and sucks air under the self expansion elasticity of the sealed air bag 12, the sealed volume is increased, the air pressure in the collecting box 1 is reduced, the negative pressure is increased, the suction force is increased, the air pressure in the control air bag 6 is greater than the outside, the control air bag, the elastic air bag 4 is reduced, the diameter of the inlet is enlarged, the blocked coagulum and the like easily enter the drainage tube 2 under the action of negative pressure increasing and extracting force and the enlargement of the inlet at the moment, and the diameter of the entering coagulum and the like is smaller than that of the drainage tube 2 through extrusion compression. If the coagulum is still blocked at the inlet after once extrusion compression, the elastic air bag 4 is rapidly expanded and reduced for a plurality of times under the control of the processor by driving the motor to rapidly act, so that the diameter of the coagulum can be reduced or even broken, and finally the coagulum is extracted by negative pressure and is recovered to a stable working state.

The pulse type negative pressure working state can be controlled by the timer module or manually controlled, works for a short time after being opened once, such as five seconds and the like, does not need too long time due to high-frequency action, and the next working period can be immediately opened when the negative pressure rises even if the negative pressure is not solved in one working period. In the pipe head 3, the volume of the elastic air bag 4 is small, and rapid adjustment can be performed.

When the pulse type negative pressure working state is entered, the processor can also firstly control the negative pressure pump 9 to increase the working power, and pulse regulation is carried out under a relatively larger negative pressure state (the negative pressure is in the safe negative pressure), so as to increase the suction force.

As shown in fig. 3-5, injector 8 can inject gas into the elastic balloon 4 and the control balloon 6 through branch tube 7 and airway tube 5, so as to change the amount of gas on the basis, and finally the diameter of the inlet formed by the elastic balloon 4 is controlled by the adjustment of injector 8. When the tube head 3 enters a human body, the elastic air bag 4 can be expanded to the maximum state through the injector 8, the end part of the tube head 3 is closed, and the blockage caused by inserting some substances or tissues into the end part of the tube head 3 when the tube head passes through the human body to enter can be avoided; if the left end of the tube head 3 is wrapped by the elastic air bag 4, an arc surface is formed in an expansion state, so that the resistance of entering a narrow part of a human body can be reduced; when the liquid accumulation extraction is completed or stopped, the end part of the tube head 3 is blocked by the expansion of the elastic air bag 4 through the injector 8, so that the liquid accumulation in the overflow tube can be prevented from flowing backwards.

The sealing air bag 12 can be positioned by a conventional fixed mounting structure and a guide structure to ensure that the cam 14 is directionally deformed in a telescopic manner when acting on the sealing air bag 12.
