Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a liver cirrhosis ascites aspirator. Background Art

[0002] Liver cirrhosis is a common chronic progressive liver disease in clinical practice. It is a diffuse liver damage caused by the long-term or repeated effects of one or more causes. In my country, most cases are post-hepatitis cirrhosis, and a small number are alcoholic cirrhosis and schistosomiasis cirrhosis. Liver cirrhosis can easily lead to abdominal water accumulation, which requires a medical aspirator for suction. However, the existing ascites aspirator is inconvenient to control the suction speed of the suction pump, which can easily make the patient feel uncomfortable during suction, affecting the use of the aspirator. In addition, the suction pump is inconvenient to carry due to its large size.

[0003] The utility model with publication number CN215460650U discloses a liver cirrhosis ascites aspirator, comprising a driving chamber, a handle, a suction device, a liquid storage cylinder and a pipette, wherein the handle is arranged under the bottom wall of the driving chamber, the suction device is arranged in the driving chamber, the liquid storage cylinder is arranged on the outer side wall of the driving chamber, and the pipette is arranged on the side wall of the liquid storage cylinder.

[0004] The device solves the problem of carrying and controlling reflux, but ascites has a certain amount, and the device can only be extracted once when in use. When the ascites fills the liquid storage cylinder, continuous suction cannot be performed, and the device needs to be removed from the human body, the sucked ascites must be squeezed out and then connected to the human body for suction. This process is cumbersome, and the secondary disassembly and connection can easily cause damage to the human body's wounds, making it inconvenient to use. Utility Model Content

[0032] Specifically, the suction bucket 2 is fixedly installed on the bottom of the suction frame 1 by means of provided screws.

[0033] One end of the piston rod 22 movably passes through the suction frame 1 and is fixedly connected to a positioning block 221 . One end of the piston rod 22 movably connects to a connecting sleeve 222 . The positioning block 221 is located inside the connecting sleeve 222 . The connecting sleeve 222 is threadedly matched with the pull rod 12 .

[0034] By adopting the above technical solution, it is convenient to connect and install the piston rod 22 and the pull rod 12. First, align the piston rod 22 with the bottom end of the pull rod 12, and then move the connecting sleeve 222 so that the connecting sleeve 222 can be threadedly connected with the pull rod 12, so that the positioning block 221 can be squeezed at the bottom end of the pull rod 12 for connection, so as to facilitate the disassembly and assembly of the pull rod 12 and the piston rod 2, wherein the suction barrel 2 can be fixed to the suction frame 1 by screws, so as to facilitate the disassembly and assembly between the suction frame 1 and the suction barrel 2, and facilitate the disassembly and assembly of the suction barrel 2 for cleaning.

[0035] Specifically, the liquid storage barrel 5 is made of a transparent material, and scale lines are arranged on the outer surface of the liquid storage barrel 5 .

[0036] By adopting the above technical solution, the liquid storage barrel 5 is made of transparent material so that the liquid level inside can be observed, and the scale lines on the liquid storage barrel 5 can be used to accurately observe the amount of ascites inhaled.
