Radio capsule type medical device

Abstract

The invention discloses a radio capsule type medical device. The device comprises a radio endoscopic capsule and a recording instrument, wherein the radio endoscopic capsule is used for receiving a control instruction of the recording instrument, photographing a living body cavity and sending the obtained images to the recording instrument; the recording instrument is used for calculating the similarity of the received two adjacent images; determining the current acquiring frequency of the radio endoscopic capsule according to the correspondence relationship that the acquiring frequency lowers down as the similarity increases; distributing the control instruction for adjusting the acquiring frequency of the radio endoscopic capsule. According to the device, the acquiring frequency can be changed as the peristalsis speed of the alimentary canal; the acquiring frequency can be increased in an area in which the peristalsis of the alimentary canal is fast, so as to avoid ignoring of detection; in addition, the acquiring frequency can be increased in an area in which the peristalsis of the alimentary canal is slow, and thus the images with high repeatability can be avoided.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a radio capsule medical device. Background technique [0002] At present, the detection of the digestive tract in the living cavity includes gastroscope, duodenoscope, enteroscope, colonoscope and capsule endoscope. Traditional endoscope is the most important tool for gastrointestinal diseases because of its better field of view and controllability. Observation means, but the disadvantage is that it can only inspect specific parts of the digestive tract, and it will bring some pain to the examinee, so that people have a certain fear of traditional endoscopy. The capsule endoscope that appeared later can conduct comprehensive and continuous inspection of the entire digestive tract, and because of its small size and painless inspection, it has been better applied. [0003] However, the capsule endoscope also has its significant disadvantages: because the capsule endoscopes curren...
