Description

Peep capsule in the medical radio

Technical field

This utility model relates to medical monitoring, checkout gear system, specifically is that a kind of gastrointestinal tract that can enter is peeped in carrying out in the medical radio of observation and peeped capsule-type.

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 in a kind of medical radio and peeps capsule, 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: peep capsule in promptly a kind of medical radio, the optics protecgulum that comprise housing, is connected with housing, sequence arrangement are 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 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, can understand gastral image in the wireless transmit in real time.

Description of drawings

The embodiment of the indefiniteness that said structure of the present utility model can provide by accompanying drawing further specifies.

Accompanying drawing 1 is to peep capsular structural profile sketch map in the radio;

Accompanying drawing 2 is circuit theory diagrams of peeping capsule embodiment in the radio;

Accompanying drawing 3 is for peeping the magnetic switch circuit theory diagrams of capsules A in the radio;

Accompanying drawing 4 is the sketch map of this utility model embodiment;

Referring to accompanying drawing: peep capsule, B-portable image monitor, C-external memory storage, D-storage medium reader, E-computer medical image work station, the antenna array of F-portable image monitor, 1-intestinal, 2--optics protecgulum, 3-LED illumination array, 4-optical lens, 5-imageing sensor, 6-microprocessor, 7-battery, 8-magnetic switch module, 9-radio-frequency (RF) receiving and transmission module, 10-antenna, 11A-temperature sensor, 11B-pressure transducer, 12-housing among the figure in the A-.

The specific embodiment

This utility model comprises storage medium reader D and the external memory storage C thereof that peeps capsules A, portable image monitor B and antenna array F thereof in the radio and be connected with computer medical image work station E; Antenna array F is the antenna array of being made up of 3～8 radio receiving units, patient is worn on antenna array F around the abdominal part by special vest, one of its effect is to peep the data that capsules A sends in the radio in order better to accept, and it two is to provide information for peeping capsules A location in vivo in the radio.

Fig. 1 is the internal structure of peeping capsules A embodiment in the radio that is in the intestinal wall 1.Peeping in the radio in the capsular housing is optics protecgulum 2, white light LED array 3, camera lens 4, imageing sensor 5, microprocessor 6, button cell 7, magnetic switch 8, radio-frequency (RF) receiving and transmission module 9, antenna 10 from left to right successively, and its middle shell 12 is bonded as one with optics front shroud 2.In the present embodiment, temperature sensor 11A is installed or/and pressure transducer 11B in the capsule housing, wherein pressure transducer 11B is close to inner walls and installs, and their outfan is connected with the I/O mouth of microprocessor 6.
