Cirrhosis ascites suction apparatus

Abstract

The invention relates to the field of medical instruments, and specifically relates to a cirrhosis ascites suction apparatus. The cirrhosis ascites suction apparatus comprises an arched placement piece, an arched cover piece which is connected with the left side of the arched placement piece by a hinge and matched with the arched placement piece, a syringe which is seized inside the arched placement piece, and a suction needle which is connected with the rear end of the syringe by a tube; a sliding piece is arranged on the bottom side of the middle part of the arched placement piece in a sliding way; a first concave seizing piece is arranged on the front part of the upper side of the sliding piece; a grip is connected with the rear side at the lower side of the sliding piece by a hinge; ahandle is arranged at the lower part of the front side of the arched placement piece; the bottom end of the handle is connected with a torsion spring at the bottom end of the grip; second concave seizing pieces are arranged both on left and right inner walls of the middle part of the arched placement piece; a threaded pipe is arranged at the lower side of the front part of the arched placement piece; and the bottom end of the threaded pipe is in threaded connection with a liquid collection bottle. The cirrhosis ascites suction apparatus is simple in structure, convenient to use and feasible for one-hand operation so as to facilitate control over suction rate; and moreover, continuous ascites suction can be realized by continuously gripping and releasing the grip, so that efficiency of ascites suction can be improved. In addition, the cirrhosis ascites suction apparatus enables disassembly of the liquid collection bottle, the syringe and the suction needle from the arched placement piece, so that washing and disinfecting can be facilitated.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a suction device for liver cirrhosis ascites. Background technique [0002] When the patient suffers from liver cirrhosis ascites disease, the medical staff uses the aspirator to extract the ascites in the patient's body, which is convenient for surgery and rehabilitation. The liver cirrhosis ascites aspirator is widely used in hospitals and is also one of the common medical devices at present. [0003] At present, the extraction needle is mainly connected through the catheter through the syringe. After the extraction needle is inserted into the patient's body, the core rod of the syringe is pulled to drive the piston to move away from the inlet of the syringe, thereby extracting the ascites from the patient's body. [0004] However, the use of syringes in the application process also has the following defects and deficiencies: [0005] Continuous extraction of ascites cannot be...

Problems solved by technology

[0007] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a cirrhosis ascites aspirator, which can effectively solve the problem in the prior art that continuous extraction of ascites cannot be realized. If the ascites is to be extracted again, the syringe needs to be separated from the catheter first. , and then discharge the ascites in the syringe, and finally connect the syringe to the catheter and extract it, resulting in cumbersome operation steps; secondly, to operate the syringe, it is necessary to hold the syringe with one hand and pull the core rod with the other hand, resulting in extraction Inconvenient question
