Referring to fig. 1, when it is desired to suck air from the storage bottle 3, the push-pull rod 13 is pulled, the piston 12 moves in a direction away from the storage bottle 3, and the air from the storage bottle 3 is sucked into the suction portion 1.

In order to prevent the reverse flow of air into the storage bottle 3, as an alternative embodiment, referring to fig. 1, a main pipeline 5 is arranged on a pipeline of the storage bottle 3 communicated with the suction part 1, a first one-way valve 6 is arranged on the main pipeline 5, and the first one-way valve 6 only allows the gas to flow from the storage bottle 3 side to the suction part 1 side. When the operator loosens the push-pull rod 13, due to the existence of the first one-way valve 6 on the main pipeline 5, even if the storage bottle 3 is in a negative pressure environment, air cannot be reversely sucked back into the storage bottle 3, so that the negative pressure environment is continuously maintained in the storage bottle 3.

In order to realize continuous suction of the suction part 1 and further improve the vacuum degree in the storage bottle 3, as an optional embodiment, referring to fig. 1, a branch pipeline 9 is further connected to the main pipeline 5, one end of the branch pipeline 9 is communicated with the outlet end of the first one-way valve 6, and the other end is communicated with the outside atmosphere; a second one-way valve 7 is present on the branch line 9, the second one-way valve 7 allowing only gas to flow from the main line 5 to the outside atmosphere.

When the piston 12 moves inside the body 11 to the end of the body 11 facing away from the main conduit 5, it is necessary to expel the air inside the body 11, since it is already full of air stored inside it. The above structure can realize smooth discharge of air in the main body 11 of the suction part 1 to perform continuous suction operation. Specifically, when the air sucking device works, as shown in fig. 1, the push-pull rod 13 is pushed, the piston 12 moves towards the main pipeline 5, and due to the blocking of the first one-way valve 6, air does not enter the storage bottle 3, but is exhausted into the external atmosphere through the branch pipeline 9 and the second one-way valve 7 on the branch pipeline 9, so that the air in the sucking part 1 is exhausted, and the next sucking action is performed.

Above-mentioned first check valve 6 and second check valve 7's cooperation structure can prevent that the air from flowing back to in the storage bottle, guarantees the negative pressure environment in the storage bottle, and can make the air discharge to the air through second check valve 7 when promoting the suction portion in, realizes the continuous suction of suction portion, further improves the vacuum in the storage bottle.

Through the experiment, above-mentioned structure in this embodiment can realize realizing certain vacuum in the storage bottle 3, and can carry out the suction in succession to thrombus and bloody water.

As an alternative embodiment, in the present embodiment, a negative pressure display unit is arranged on the pipeline between the storage bottle 3 and the suction part 1, and the display unit is used for displaying the pressure indication in the storage bottle 3.
