Description

Medical radio capsule formula endoscope system

Technical field

This utility model relates to medical monitoring, checkout gear system, specifically is a kind ofly can enter the medical wireless capsule formula endoscope system that gastrointestinal tract is peeped observation in carrying out.

Background technology

Digestion endoscope comprises gastroscope, colonoscope, duodenoscope, small intestinal mirror etc.Strong because of its good visual field, controllability, can implement the diagnostic biopsy, implement ultrasonic examination and the treatment (as microwave, TURP etc.) down of various scope under the scope, now having become is that gastroenteropathy is peeped Observations Means in most important.Because splanchnoscopy whole operation process can be brought certain misery even wound to the person under inspection really, makes people have certain feared state of mind for splanchnoscopy.In addition, present gastroscope, colonoscope, duodenoscope, small intestinal mirror etc. can only be observed specific position, and can not carry out the inspection of continuous whole to whole digestive tract.

United States Patent (USP) 5,604,531 have proposed a kind of radio endoscopic system of oral capsule formula, and this digestive tract photograph capsule transmits three parts by optical imagery, photograph and image wireless to be formed, and need swallow this device just as medicament capsule to the patient that gastrointestinal is checked.Because its volume is little, no pain when swallowing does not have uncomfortable yet after swallowing.Microcam in the capsule can constantly be issued the inner sharp image of the intestines and stomach of taking in the other image recording structure between patient's waist by sender unit.Record finish after, recording apparatus is sent to hospital, the doctor reads and analyzes image data with computer, can understand the illness of the intestines and stomach.One capsules can be taken and be reached 6 hours image, after capsule is finished mission, will enter large intestine with gastrointestinal peristalsis, excretes then.The advantage of capsule endoscope is conspicuous: promptly its volume is little (present minimum 11.6mm * 27.2mm), easily swallows; Simple to operate; Do not need to be in hospital; There is not the complication that operation causes; Can realize that all-digestive tract inspection, image document can review analysis repeatedly.But at present capsule endoscope also exists tangible deficiency: because the shooting of image all is a random uptake, make the visual field limited and have certain rate of missed diagnosis; Capsule can only outwards send image information, and its duty and working method can not be controlled external, and the doctor can not control whole checking process, can not realize autotelic emphasis inspection or the like.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of medical radio capsule formula endoscope system, and it both can wireless outside transmission digital image information, but the external control instruction of wireless receiving realizes control to capsule duty and working method again.

For achieving the above object, the technical solution adopted in the utility model is such: promptly a kind of medical radio capsule formula endoscope system comprises and peeps capsule and portable image monitor in the radio; Peep optics protecgulum that capsule comprises housing, is connected with housing, sequence arrangement in the radio at the intravital LED illumination array of shell, camera lens, power switching module; It is characterized in that: also comprise imageing sensor in the capsule, image information can be converted to microprocessor, radio-frequency (RF) receiving and transmission module and the dual-mode antenna of the jpeg format of compression, wherein; The signal output part of imageing sensor connects the I/O mouth of microprocessor, the image information that receives is converted to the jpeg format of compression by microprocessor, be connected to the data receiver of radio-frequency (RF) receiving and transmission module again, send information by a day alignment portable image monitor by radio-frequency (RF) receiving and transmission module; Radio-frequency (RF) receiving and transmission module is by the control instruction that is sent by image recorder that antenna receives, and is connected to after the microprocessor processes by its I/O mouth control LED illumination array, imageing sensor and the working method of radio-frequency (RF) receiving and transmission module and the control end of duty; The portable image monitor comprises dual-mode antenna, radio receiving transmitting module, microprocessor and memory element thereof; Wherein the information that sends of radio receiving transmitting module capsule that antenna is received is connected with microprocessor by the mode of bus, or will send to capsule by antenna from the information of microprocessor control port.

The technique effect that this utility model produces owing to described structure is very tangible, promptly peeps capsule in the radio because volume is little, in light weight, and the patient takes the no fear in back; During checking do not influence walking and daily routines; Simple to operate; Do not need to be in hospital; There is not the complication that operation causes; Can realize that all-digestive tract inspection, image document can supply the doctor review analysis repeatedly.Peep in the particularly described radio capsule can be in inspection the control outside the acceptor at any time, and, can understand gastral image in the wireless transmit in real time by peeping the capsule duty in the detected pressures managing radio.
