Problems solved by technology

Gastroenterology patients have problems with the digestive tract system, which affects the normal excretion of the body. In order to specifically analyze the data of various digestive juices in the stomach, it is necessary to extract the patient's stomach digestive juice and other mixtures through equipment, and then judge by testing Stomach disease, the existing sampling device is prone to blockage due to the high viscosity of the digestive tract during sampling. At the same time, it is inconvenient to block the sampling site after sampling, and the liquid from other parts is easy to enter the sampling device, which is easy to cause confusion. make the test inaccurate

Abstract

The invention relates to a digestive tract liquid biopsy sampling device for internal medicine, and belongs to the field of medical treatment. The device includes a needle tube, needle tube with cap,push rod with cap, push rod with first piston, needle tube with connecting tube, a second one-way valve is arranged on the connecting pipe; the connecting pipe is provided with a cover plate, the cover plate is provided with a liquid accumulation barrel; the needle tube is provided with an intermediate tube, the intermediate pipe is provided with a first one-way valve, the intermediate pipe is provided with a straight pipe, the straight pipe is provided with a T-shaped push rod, the T-shaped push rod is provided with a reset structure; and the reset structure is connected with a blocking cylinder. The blocking cylinder is provided with a sleeve, the sleeve is in threaded connection with the middle pipe; through holes are formed in the blocking cylinder and the sleeve; the T-shaped push rodin the straight pipe moves upwards; the T-shaped push rod drives a connecting rope of the reset structure to move; the connecting rope drives the blocking cylinder to move through the straight rod, drives the solid part of the blocking cylinder to move to the through hole of the sleeve to block the through hole of the sleeve, and conveniently blocks the through hole part of the sleeve after sampling, so that liquid at other parts cannot enter the sampling device when the sleeve moves, the sampling correctness is ensured, and the inspection is more accurate.

Description

technical field [0001] The invention relates to the medical field, in particular to a digestive tract liquid biopsy sampling device for internal medicine. Background technique [0002] The alimentary canal is a long muscular tract that starts from the oral cavity and continues to the pharynx, esophagus, stomach, small intestine, large intestine, and finally the anal canal, including the oral cavity, pharynx, esophagus, stomach, small intestine, duodenum, jejunum, ileum, and large intestine Cecum, appendix, colon, rectum and anal canal. There are two types of digestive glands: small digestive glands and large digestive glands. The small digestive glands are scattered in the wall of each part of the digestive canal. The large digestive glands have three pairs of salivary glands, parotid glands, submandibular glands, sublingual glands, liver and pancreas. They all use ducts to discharge secretions into the digestive canal. [0003] Gastrointestinal biopsy technique is of grea...
