[0038] In the utility model, the working principle of the device is as follows:

[0039] Before the medical negative pressure drainage operation is performed, first, the collecting container 6 is fixedly installed at the bottom of the end cover 5, then the end cover 5 with the collecting container 6 is arranged on the cylindrical container 3, then the cylindrical container 3 is arranged on the mounting plate 4, the cylindrical container 3 is moved to the position corresponding to the strip-shaped block 8 by sliding the mounting plate 4, so that the strip-shaped block 8 corresponds to the gap between the two bosses 12, and the two insertion holes at the top of the end cover 5 correspond to the positions of the tracheal connector 9 and the liquid suction plug 10 and are matched. Then one end of the bending plate 14 is pressed down and the bending plate 14 is rotated, and the end is horizontally inserted into the limiting groove of the base 2. During the process, the block 16 lifts the cylindrical container 3, and the two spring telescopic columns 13 are compressed and contracted. Since the cylindrical container 3 is limited by the plurality of protrusions 7, the cylindrical container 3 can be kept vertically rising until the strip-shaped block 8 slides into the gap between the two bosses 12, and the tracheal connector 9 and the liquid suction plug 10 are inserted into the two insertion holes of the end cover 5, respectively. At this time, the tracheal connector 9 and the liquid suction plug 10 both open the rubber film in the corresponding insertion hole and communicate with the bottom of the end cover 5, that is, with the inside of the collecting container 6. Then the existing pipeline for drainage is communicated with the suction connector 11, and the device main body 1 is started, so that the negative pressure suction effect is set, that is, the gas in the inside of the collecting container 6 is sucked through the tracheal connector 9, so that the negative pressure is generated in the inside of the collecting container 6, and then the negative pressure suction operation is performed through the liquid suction plug 10, so that the pipeline connected with the suction connector 11 performs the negative pressure drainage operation.

[0040] At the same time, if there is a continuous negative pressure drainage demand, for example, after the negative pressure drainage operation of the relevant part of the patient's body is completed, the liquid in the medical container or tray needs to be cleaned, at this time, the liquid level in the collecting container 6 being used may reach the capacity warning line, so that the quick replacement of the collecting container 6 can be performed. When the quick replacement is performed, another cylindrical container 3 is arranged on the mounting plate 4 in advance, and the suction connector 11 is blocked, which can be clamped and blocked by a pipe clamp. Then the bending plate 14 is horizontally pushed to rotate the corresponding rotating disc 15, so that the bending plate 14 is separated from the limiting groove of the base 2, and the corresponding block 16 does not limit the bottom of the cylindrical container 3. At this time, the two spring telescopic columns 13 are elongated and reset, the cylindrical container 3 is reset and horizontally moved down, then the mounting plate 4 is pushed, so that another collecting container 6 is aligned with the strip-shaped block 8, then the bending plate 14 is used again to connect the collecting container 6, and the suction connector 11 is communicated, so that the negative pressure suction operation can be continuously performed. The overall operation is convenient and effective, and the work efficiency is effectively improved.

[0041] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this.
