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 13 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 solenoid valve 12 works, realizes pulsed negative pressure work, avoids blockking up.
As shown in fig. 2-4, under the working condition of pulse type negative pressure, the processor controls the electromagnetic valve 12 to be rapidly and repeatedly opened and closed, when the electromagnetic valve 12 is opened, the collecting box 1 is directly communicated with the outside, the internal negative pressure 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 expands along with the expansion, the diameter of the inlet is reduced, at the moment, the elastic air bag 4 extrudes and compresses the coagulum and the like blocked at the end part inlet, the electromagnetic valve 12 is controlled to be closed soon, at the moment, the negative pressure pump 9 extracts the air in the collecting box 1, the air pressure in the collecting box 1 is rapidly reduced, the negative pressure is enhanced, the suction force is enhanced, the air pressure in the control air bag 6 is larger than the outside, the control air bag 6 expands, at this moment, under the action of negative pressure increasing and extracting force and the expansion of an inlet, blocked coagulum and the like easily enter the drainage tube 2, and the entered coagulum and the like are extruded and compressed, and the diameter of the coagulum and the like is smaller than that of the drainage tube 2. If the coagulum is still blocked at the inlet after once extrusion compression, the electromagnetic valve 12 acts at high frequency under the control of the processor, the elastic air bag 4 is rapidly expanded and reduced for many times, 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 effusion extraction is finished 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, and the effusion in the drainage tube 2 can be prevented from flowing backwards.
