Embodiment 1

[0020] This embodiment provides a capsule endoscope for checking esophageal diseases, which has such as Figure 1-2 The shown structure includes a capsule housing 1, a pH sensor 2 disposed in the capsule housing 1, an imaging device, a control device 4 and a micro-motor 5, and also includes an air bag 6, and an inflation / deflation device connected to the air bag 6. Device 7, pressure sensor 8, acceleration sensor 9 and power supply 10, wherein:

[0021] The capsule shell 1 is a cylinder with hemispherical ends at both ends, and the middle part of the cylinder of the capsule shell 1 is a circle of transparent body. The transparent body of the casing 1 acquires an external image;

[0022] The airbag 6 is a transparent body, which is coated on the outer periphery of the cylinder of the capsule housing 1, and the inflation / deflation device 7 and the pressure sensor 8 are all arranged in the capsule housing 1, and the inflation / deflation device 7 includes Gas generator 71, the in...

Embodiment 2

[0028] This embodiment provides another capsule endoscope for checking esophageal diseases, which has the following functions: Figure 3-4 The structure shown, wherein: the inflation / deflation device 7 includes an inflation valve 71, an air suction or exhaust valve 72 and a gas storage bin, and the gas storage bin includes an air intake bin 73 and an air deflation bin 74, the The volume of the air intake chamber 73 is larger than that of the air discharge chamber 74, and the air intake chamber 73 is initially in a vacuum state, and non-toxic and tasteless transparent compressed gas is stored in the air discharge chamber 74, and the inflation valve 71 is located in the air discharge chamber 74, the suction or exhaust valve 72 is set on the intake chamber 73, the inflation valve 71 and the suction or exhaust valve 72 are driven by the control device 4; when the capsule endoscope reaches the esophagus to be detected , the control device 4 opens the inflation valve 71, and the gas...

Abstract

The invention discloses a capsule endoscope for examining esophageal diseases. The capsule endoscope comprises a capsule shell, an imaging device, a control device, an air bag, an inflation / deflation device connected with the air bag, and a pressure sensor, wherein the air bag is transparent and arranged on the periphery of the capsule shell, the inflation / deflation device and the pressure sensor are both arranged in the capsule shell, the inflation / deflation device is used for driving the air bag to be opened or contracted, and the pressure sensor is used for measuring the pressure of air in the air bag. According to the capsule endoscope, the size of the air bag can be controlled through the inflation / deflation device according to the pressure or peristalsis force of the esophagus wall, so that sufficient contact between the air bag and the esophagus wall is achieved, the moving speed of capsules is reduced, the esophagus is stretched, and then the image or video of the esophagus wall can be acquired easily and the lesion part of the esophagus wall can be treated.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to a capsule endoscope for checking esophageal diseases. Background technique [0002] Esophageal diseases mainly include esophageal tumors, gastroesophageal reflux disease, and Barrett's esophagus. The commonly used diagnostic methods mainly include esophagoscopy, esophageal X-ray barium meal examination, and CT scan. At present, the early detection of esophageal cancer mainly relies on traditional esophagoscopy for screening. Esophagoscopy adopts a mechanical insertion method, which is an invasive examination. The patient has many discomfort reactions and is easy to damage the throat, causing great pain, and sometimes requires sedation and anesthesia. Esophageal X-ray barium meal examination can detect esophageal deformities and abnormal movements, but the detection rate of small lesions is low; CT scan examination can detect intramural lesions and extracavitary l...
