PLC-controlled external bile regurgitation apparatus

Abstract

The invention provides a PLC-controlled external bile regurgitation apparatus comprising a housing, a bile storage bag inside the housing, an inlet guide tube and an outlet guide tube. The inlet guide tube and the outlet guide tube are connected with the bile storage bag and disposed on the housing. A peristaltic pump, a motor connected with the peristaltic pump, a PLC (programmable logic controller) for controlling the motor and a detection sensor for detecting bile storage in the bile storage bag are disposed inside the housing. The detection sensor is connected with the PLC. The peristaltic pump is disposed at the outlet end of the bile storage bag. The detection sensor is disposed at the inlet end of the bile storage bag. The outlet guide tube is connected with the bile storage bag through the peristaltic pump. The PLC-controlled external bile regurgitation apparatus is simple in structure and convenient to use; the detection sensor allows the apparatus to detect stored quantity of bile in the bile storage bag in real time; the PLC allows the apparatus to automatically control stored quantity of bile; external bile regurgitation can be achieved timely and effectively; compared with the prior art, the PLC-controlled external bile regurgitation apparatus is high in regurgitation efficiency, accuracy and practicality.

Description

technical field [0001] The invention relates to the technical field of extracorporeal bile reflux instrument, in particular to a PLC-controlled extracorporeal bile reflux instrument. Background technique [0002] With the rapid development of society, the research on bile components has also been rapidly developed. It has been confirmed that bile contains not only a large amount of electrolytes, but also rich in protein and bile acids, which play an extremely important role in the human body. In some patients with biliary obstruction, extracorporeal drainage devices are generally required. Existing extracorporeal bile reflux devices generally require patented on-duty drainage, which can complete extracorporeal reflux to a certain extent. However, due to the need for manual on-duty, it is highly dependent on personnel , it will be difficult to achieve timely and effective reinfusion to a certain extent, the flow rate is difficult to control and the waste of bile is also serio...
