AUTOMATIC DEVICE FOR EXAMINING FUNCTIONAL CONDITION OF LOCKING MECHANISM OF RECTUM AND MEASUREMENT AND DOSAGE IRRITATION UNIT Russian patent published in 1994 - IPC

FIELD: medical equipment. SUBSTANCE: device for examining functional condition of rectum has commutation and indication unit, measurement and dosage irrigation unit 2 and multichannel catheter 3 equipped with small containers. Catheter 4 has three small containers - irrigating and two reflex containers. Reflex containers are provided with sphincter muscular system electric activity detectors. Commutation and indication unit is made in form of personnel computer which has input and output connected with measurement and dosage irritation unit. The second output of unit 2 is connected with irritating container of multichannel catheter 3 and the second input is connected with sphincter muscular system electric activity detectors and with reflex containers. Measurement and dosage irritation unit of the device has pressure source, pressure regulator and meter, miographic unit and analog-to-digital converter. Pressure source is connected with regulator through reducer to form dosage irritation unit. The first input of measurement and dosage irritation unit is connected with dosage irritation unit which is connected with the second output. The second input is connected with pressure measurement unit and with miographic unit. Pressure measurement unit and miographic unit are connected with the first output through analog-to-digital converter. EFFECT: automatic measurement of characteristics of sphincter; improved truth of detection of pathology; continuous automatic measurement of signal parameters. 2 cl, 4 dwg
