In combination with the above embodiment, the use principle and working process of the embodiment of the present invention are as follows:
In the initial state, the sliding plate 400 is positioned at the bottom of the suction tube 200 under the action of the tension spring 401, and the gastric tube 100 is closed by using the clip. The sliding block of the sliding plate 400 slides along the spiral groove of the central shaft 202 by the hand stretching into the annular through groove 203 at the bottom of the suction cylinder 200 and rotating the sliding plate 400, so that the sliding plate 400 rotates anticlockwise (from top to bottom) and moves upwards, the sliding plate 400 rotates anticlockwise to drive the rotating frame 300 to rotate anticlockwise, the four storage cavities also rotate anticlockwise, the upward movement of the sliding plate 400 drives the diaphragm 304 to be rolled by the scroll 305, the volumes of the four storage cavities are gradually reduced until the gas in the four storage cavities is discharged through the gas outlet 205, and then the cover on the gas outlet 205 is covered, so that the gas outlet 205 is closed, and the volumes in the storage cavities are reduced to the minimum. Then, the sliding plate 400 is released, the sliding plate 400 can move downwards under the action of the tension spring 401 and simultaneously rotate clockwise, the sliding plate 400 moves downwards to drive the diaphragm 304 to stretch downwards, the volumes of the four storage cavities are gradually increased to form negative pressure, the negative pressures of the four storage cavities are nearly consistent, and meanwhile, the four storage cavities rotate clockwise. The first storage chamber is set to communicate with the liquid inlet 204, and is a second storage chamber, a third storage chamber and a fourth storage chamber in the counterclockwise direction, respectively. Then, the stomach tube 100 is opened, the stomach contents firstly enter the first storage cavity under the action of negative pressure, so that the pressure in the first storage cavity is gradually increased, and the negative pressure of the second storage cavity, the third storage cavity and the fourth storage cavity is kept at a set value under the action of the pressure stabilizing valve 201.
When the sealing rod 302 shared by the first storage cavity and the second storage cavity rotates to a position contacting the pressure release spring 2022, the pressure release spring 2022 is pressed to enable the sealing cover 2021 to open the opening on the suction barrel 200, so that the sucked first storage cavity is communicated with the outside, and the first storage cavity is in a normal pressure state. With the clockwise rotation of the slide plate 400, the second, third and fourth storage chambers are sequentially filled with the stomach contents and become an atmospheric pressure state. Because the negative pressure of each storage cavity is basically consistent, the suction force on the gastric contents is close.
In the above process, when the first storage chamber and the second storage chamber, the third storage chamber and the fourth storage chamber are all in the negative pressure state, the annular communication port 3024 is closed by the air deflector 3021 in the pressure release chamber in each seal lever 302 under the action of the negative pressure, so that the first storage chamber and the second storage chamber, the third storage chamber and the fourth storage chamber are kept in the negative pressure state. When the first storage cavity, the second storage cavity, the third storage cavity and the fourth storage cavity are sequentially filled with gastric contents, the gastric contents are no longer negative pressure, the wind shield 3021 in the pressure release cavity in each sealing rod 302 opens the annular communication port 3024 under the action of the spring 3022, so that each storage cavity is kept in a normal pressure state. So that the storage cavity, which has been filled with the stomach contents, can be maintained in an atmospheric pressure state during the continued clockwise rotation and downward movement of the slide plate 400.
After the first storage cavity is filled with the gastric contents, if the gastric contents do not need to be continuously extracted, the gastric tube 100 can be closed, the sliding plate 400 is pressed to prevent the gastric contents from moving downwards, after a certain time, the gastric contents need to be extracted again, the gastric tube 100 can be opened, the sliding plate 400 is loosened to continuously move downwards and rotate clockwise, so that the gastric contents can be extracted in different time periods, and the gastric contents in different time periods are prevented from being mixed.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
