METHOD AND DEVICE FOR CONTROLLING EVACUATION ACTIVITIES OF GASTROINTESTINAL TRACT Russian patent published in 2003 - IPC

FIELD: medical engineering. SUBSTANCE: chyme evacuated from oral segment of intestine comes to receiving reservoir via cannula tube. Its volume is measured (at 1 ml accuracy level) in given time interval. Aliquot is taken for investigating parameters under study. Chyme is poured into supplying reservoir in 5-10 min long intervals and delivered into anal segment of intestine after being heated to 39 C via catheter through locking unit of anal arm of the cannula designed as ball cork manufactured from spongy rubber. The flow returning chyme into the intestine is continuous owing to special purpose regulator device operating. EFFECT: high accuracy of measurements. 2 cl, 1 dwg
