During use, by squeezing the relevant suction The liquid balloon can carry out the negative pressure suction of liquid to the relevant parts of the patient through the suction tube. Although it has a simple structure and is easy to use, it still has many defects and deficiencies.

Specifically, on the one hand, the size of the balloon has been limited. When the balloon is filled with the absorbed liquid, it cannot continue to absorb the liquid continuously, which makes the practicability not strong. On the other hand, when the related suction After the liquid balloon is filled with the absorbed liquid, when it is necessary to further absorb the liquid from the relevant parts of the patient, it is necessary to disassemble the relevant liquid suction balloon, pour out the absorbed liquid, and then connect the relevant liquid suction balloon with the corresponding The suction tube is connected, and then continue to suck the liquid of the relevant parts of the patient. The disadvantage of this method is that when the related liquid suction balloon is disassembled and the relevant liquid is squeezed out, bacteria in the air can easily pass through the liquid suction. The suction of the balloon enters the relevant suction balloon, causing the balloon itself to cause pollution. When it is used for a long time, the bacteria contaminated by the relevant suction balloon will also be transferred to the corresponding suction tube due to extrusion, and then passed on. To patients and nurses, causing cross-infection.

Therefore, aiming at the current situation, it is very necessary to improve the existing negative pressure suction device provided with a balloon so that it has strong practicability, good use effect, no bacteria contamination, no cross-infection, etc. It must have promotional significance.
