Abstract

The invention relates to the field of medical instruments, in particular to a liver and gall drainage device which comprises a drainage tube, a control line, a connection tube, a catheter, a liquid storage bottle and a negative pressure generating device. The lower portion of the catheter is arranged at the bottom of the liquid storage bottle. The liver and gall drainage device is characterized by further comprising a flow limiting device which comprises a fixing block, a partition, a guide rod, a spring, a pressing plate and an ejector rod, a liquid incoming one-way valve is arranged in the middle of the catheter, two extensible rods are arranged below the fixing block symmetrically according to the liquid storage bottle, and a sucker is fixedly connected at the lower end of each extensible rod. The liver and gall drainage device is simple in structure, the liquid storage bottle can be well fixed to avoid being kicked down, and the problem of organ injury caused by overhigh liquid drainage speed can be prevented.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a hepatobiliary drainage device. Background technique [0002] In order to effectively treat diseases such as cholestasis, obstructive jaundice, and secondary infection caused by obstruction of the biliary system, percutaneous transhepatic biliary puncture can be performed under the guidance of medical imaging equipment through puncture needles, drainage catheters, etc. Tube drainage, so as to restore liver and gallbladder function, so as to achieve the purpose of treatment.
