[0002] Surgery is the science that studies the occurrence, development and clinical manifestations of surgical diseases, as well as the diagnosis, prevention and treatment. It is a professional department that mainly treats diseases through surgical resection and repair. With the application of microsurgery technology, surgery has made great progress. The principles for setting up surgical departments in various hospitals are similar to those for internal medicine, and usually correspond to internal medicine. However, secretion samplers are required in the nursing of hepatobiliary and pancreatic surgery.

[0003] The above device does not have a structure for metering and partitioning the diversion fluid when in use, so that when the existing samplers divert the pancreatic fluid, most of them directly use the catheter to divert the pancreatic fluid into the storage bottle, and the diversion amount of the pancreatic fluid cannot be controlled.

[0036] Working principle: When a secretion sampler is used, first of all, when sampling pancreatic fluid, the pancreatic duct needs to be cut close to the intestinal wall, ligated and fixed, and connected to the catheter, so that the colorless pancreatic fluid can be seen flowing into the guide tube 2, and then flowing into the interior of the quantitative mechanism 4 through the guide tube 2, and then it is measured, and then introduced into the interior of the sampling bottle 1, so as to facilitate quantitative sampling;

[0037] When quantitative sampling is required, the sealing cover 304 is first rotated so that the through hole 306 coincides with the exhaust hole 303. At this time, the secretion liquid inside the guide tube 2 flows into the interior of the liquid storage tank 404 through the one-way valve 201, and the dosage of the secretion liquid can be observed through the scale plate 402. After sufficient sampling, the sealing cover 304 is rotated again to make the through hole 306 away from the exhaust hole 303. At this time, the sampling bottle 1 is sleeved on the bottom of the quantitative barrel 401, and then the sealing push rod 405 is pressed downward to allow the secretion liquid to be guided from the inside of the pressure valve 406 into the inside of the sampling bottle 1, and the sampling can be quantitatively completed.
