At present, push-endoscopy make patients with alimentary tract disease feel uncomfortable. Especially for the focus of small intestine hemorrhagic disease, push -endoscope is difficult to reach, and even though the push-endoscope could be capable to reach, on the insert process push-endoscope may bring terribly pain. Many patients are in dread of this kind of vulnerable endoscopy and give up checking, which makes diagnoses difficult. New born capsule endoscope, taken orally, passes alimentary canal safely, shoots tens of thousand pictures, can complete the examination of small intestine pathological without pain. This text developed a portable, low cost and simple capsule endoscope medical system, we hope to be redounding to the popularization of capsule endoscope and benefit the patients.Our system, start with the image data real time transfers, use maturity USB Isochronous Transfer technology accomplish high-data-rate image transfer for the capsule endoscope, at the same time we store the images in the computer directly and leave out out-body image storage device, which is a new try and does not reported domestic and overseas in the present study of capsule endoscope.On the base of realization of the key technology of real time data transfers, we emphasize reducing the cost of capsule endoscope system. As to the abuses of that analog circuits mix digital ones, special components mix general ones, and overfull append devices in domestic and overseas capsule endoscope electric systems, we introduce a full digital, high-integration and simple-configuration idea for the design of capsule endoscope electric system, then designed and made camera module, wireless transceiver module and USB data transfer module. Camera module and USB data transfer module are all well working, which has provided a solid foundation for the study of capsule endoscope next step.
