[0002] Nasal bile duct is generally used for endoscopic nasobiliary drainage. It is established on the basis of diagnostic retrograde cholangiography (ERCP) technology and is a more commonly used endoscopic bile drainage method. It uses a thin plastic tube to be inserted into the bile duct through the duodenal papilla under endoscopy, and the other end is led out of the body from the nostril through the duodenum, stomach, esophagus, pharynx, etc., to establish an extracorporeal drainage route for bile.

[0003] However, there are still some problems with the existing nasobiliary drainage devices. In order to collect the drained bile, the nasobiliary duct is connected to the nasobiliary drainage bag, and the bile is collected through the nasobiliary drainage bag. However, the existing nasobiliary drainage bag will cause the bag to deform after containing the bile, which will lead to inaccurate readings of the bile volume. At the same time, in the actual operation process, some patients need to return the bile. For such patients, their bile needs to be transported to the drainage bag, and then the bile is poured out through the outlet pipe arranged under the drainage bag, and filtered through a filter net or gauze. The operation in this process is relatively complicated and will increase the chance of secondary contamination.

DETAILED DESCRIPTION

[0025] After the applicant's research and analysis, the reason for this problem (bile contamination during the filtering process) is that there are still some problems with the existing nasobiliary drainage devices. In order to collect the drained bile, the nasobiliary duct will be connected to the nasobiliary drainage bag, and the bile will be collected through the nasobiliary drainage bag. However, after the existing nasobiliary drainage bag contains bile, the bag will be deformed, which will lead to inaccurate readings of the bile capacity. At the same time, in the actual operation process, some patients need to return the bile to the bile. For such patients, their bile needs to be transported to the drainage bag, and then the bile is poured out through the outlet pipe arranged under the drainage bag, and filtered through a filter net or gauze. The operation in this process is relatively complicated and will increase the chance of secondary contamination. In order to complete the nasobiliary drainage work for the patient, the present invention provides a sample bottle, an adjusting part arranged at the top of the sample bottle, a drainage tube connected to the adjusting part, and a water outlet pipe arranged at the bottom of the sample bottle; wherein, the adjusting part is provided with an inlet and two An outflow port, and a filter screen arranged at one of the outflow ports; by making bile flow out from different outflow ports, when bile is reinfused, the filter screen located at one of the outflow ports can filter impurities in the bile; when bile enters the sample bottle along the drainage tube, it will pass through the adjustment part, and then the medical staff will choose whether to perform bile reinfusion according to the actual situation of the patient. When bile reinfusion is not required, it can flow into the sample bottle from the outflow port directly opposite to the inflow port, and then when bile reinfusion is required, the medical staff will turn the adjustment knob, and the operating adjustment knob can drive the adjustment rod to move, thereby adjusting the position of the guide block, thereby making one end of the guide groove abut against the inflow port, and the other end abut against one end of the outflow port with the filter screen, thereby driving the inflow direction of the bile, thereby completing the filtering of the bile during the transportation process, thereby not having to pour out the bile in the sample bottle again, thereby avoiding secondary contamination of the bile, and at the same time, by replacing the bag with a bottle, thereby ensuring the accuracy of the bile volume reading.
