In the existing technology, a hole is generally made in the patient's abdominal cavity, and then the ascites is suctioned through an aspirator to relieve the condition of patients with cirrhosis. During use, the aspirator in the existing technology continuously absorbs ascites into the liquid storage tank. However, during the suction process, if the ascites is forgotten, the liquid storage tank is prone to overflow.

DETAILED DESCRIPTION

[0021] The present invention is further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention made by those skilled in the art fall within the scope defined by the claims attached to this application.

[0022] Example 1

[0023] like Figure 1 As shown, the present invention comprises an aspirator assembly and a linkage anti-overflow assembly. The aspirator assembly is used to automatically aspirate ascites. Specifically, the aspirator assembly comprises a negative pressure aspirator 11, a suction tube 12 connected to the negative pressure aspirator 11, a liquid storage tank 13 connected to the suction tube 12, a liquid pipette 14 connected to the top of the liquid storage tank 13, and a liquid pipette head 15 connected to the end of the liquid pipette 14.

[0024] Specifically, the user inserts the pipette 14 into the abdomen of the patient with cirrhosis, and then starts the negative pressure suction machine 11. At this time, extraction is performed through the suction pipe 12. At this time, the liquid storage tank 13 forms a negative pressure environment, and ascites can be suctioned through the pipette 14 and the suction head 15.

[0025] like Figure 2-3 As shown, in order to avoid the overflow of the sucked liquid, a linkage anti-overflow component is adopted in this embodiment. Specifically, the linkage anti-overflow component consists of a guide rod 21 fixed in the liquid storage tank 13, a floating plate 22 fitted with the guide rod 21, a circular hole 23 opened on the surface of the floating plate 22, a threaded long rod 24 passing through the floating plate 22, a rubber plug 25 fixed at the top of the threaded long rod 24, and a threaded ring 26 connected to the threaded long rod 24.

[0026] Specifically, when the ascites is sucked into the liquid storage tank 13, the float 22 floats on the ascites. At this time, the ascites will lift the float 22 upward. At this time, the float 22 interacts with the surface of the guide rod 21 through the circular hole 23. When the liquid level of the ascites in the liquid storage tank 13 is at a critical value, the rubber stopper 25 is fitted with the channel opening of the suction tube 12. At this time, the suction tube 12 is blocked to avoid the situation where continued suction causes ascites to overflow. The user can adjust the position of the rubber stopper 25 as a whole by rotating the position of the two threaded rings 26, so that the user can freely adjust the critical value of the wastewater storage in the liquid storage tank 13, thereby improving applicability.

[0027] Example 2

[0028] In order to avoid the situation where the suction organ 12 is blocked due to insufficient buoyancy, the buoyancy of the floating sheet 22 is increased and adjusted by auxiliary components in this embodiment. Specifically, Figure 4 As shown, the auxiliary assembly comprises an annular foam sheet 31, an annular sleeve 32 fixed to the top of the annular foam sheet 31, a threaded hole 33 formed in the surface of the annular sleeve 32, and a threaded rod 34 extending through the threaded hole 33. During use, the annular sleeve 32 and the floating sheet 22 are nested together, and the end of the threaded rod 34 abuts against the side wall of the floating sheet 22. This allows the annular foam sheet 31 to cover the floating sheet 22, increasing the contact area between the floating sheet 22 and the ascites, and ensuring that the rubber stopper 25 fits snugly with the pipette 14.

[0029] like Figure 1-4 As shown, a method of using an ascites suction device is as follows: the operator inserts a pipette into the abdomen of a patient with cirrhosis, and then starts a negative pressure suction machine. At this time, extraction is performed through the suction tube. At this time, a negative pressure environment is formed in the liquid storage tank, and ascites can be suctioned through the pipette and the suction head. When the ascites is sucked into the liquid storage tank, the float floats on the ascites. At this time, the ascites will lift the float upward. At this time, the float interacts on the surface of the guide rod through the circular hole. When the liquid level of the ascites in the liquid storage tank is at a critical value, the rubber stopper is fitted with the channel opening of the suction tube. At this time, the suction tube is blocked to avoid the situation where ascites overflows due to continued suction. The user can adjust the position of the rubber stopper as a whole by rotating the position of the two threaded rings, so that the user can freely adjust the critical value of the liquid storage tank for storing wastewater, thereby improving applicability.
