Abstract

The invention relates to the technical field of medical sampling instrument, in particular to a swallow-type esophagus sampling device. The swallow-type esophageal sampling device provided in the embodiment of the invention comprises an airbag for sampling, an injection device and a catheter for connecting the injection device and an accommodating chamber. During use, the airbag in a contracted state is directly swallowed, and when it reaches the esophagus, the injection device is used to allow gas to enter the airbag through the catheter, the volume of the airbag is increased, and the cells to be sampled in the esophagus are adhered; after the sampling is completed, the gas in the airbag is discharged through the catheter, the volume of the airbag is reduced, and the airbag is pulled outthrough the catheter, at this time, the esophageal surface cells adhering to the sampling part can be used in subsequent sample examination. The swallow-type esophageal sampling device provided in theembodiment of the invention adopts a small-sized structure to complete sample sampling of the esophagus and the like, thereby increasing the convenience of use and patient comfort, and the cost is low.

Description

technical field [0001] The invention relates to the field of medical sampling tools, in particular to a swallowing esophagus sampling device. Background technique [0002] Esophageal cancer is a lethal disease, the operation is difficult, and the prognosis is poor. Early diagnosis is the key to improve the survival rate and reduce the difficulty of operation. Currently commonly used early diagnosis methods include fiberoptic esophagoscopy. This is a direct visual inspection method that requires special, expensive equipment, requires sedation, and is not comfortable, making it unsuitable for widespread use. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the object of the present invention is to provide a swallowing esophagus sampling device. [0004] Embodiments of the present invention are achieved like this: [0005] A swallowing type esophageal sampling device, which includes an air bag for sampling, the air bag is...
