Abstract
The sensor probe is comprised of a catheter, in the interior of the front end of the catheter or on the lateral side, pH sensor, temp. sensor, pressure sensing air bag and air duct are installed, it can detect the pH value, pressure and temp. in stomach simultaneously to provide a comprehensive and convenient detecting means for clinical diagnosis and the reseach of gestrodynamics.
Description
The present invention relates to medical diagnostic apparatus, be used to measure the intravital physiological data of human body or animal.
The existing at present sensor probe of measuring single physiological data in human body or the experimental animals with different modes, the WO9416613 patent that world patents index is introduced, it is the gastrointestinal catheter that is used for patient P H record, be to transmit light pulse to the sampling position with optical fiber, the digital signal that analysis is returned obtains the characteristic of gastrointestinal tract sample material, its follow-up analyzing and processing circuit more complicated.The physical stress that U.S. Pat 4846191 is introduced is measured, and adopts liquid perfusion cannula conducting pressure also to link to each other with pressure transducer, and the pressure measurement end has colloid substance, and liquid in pipe is switching to pressure between jelly and pressure converter.They can only detect single pH value, pressure or temperature data, must insert respectively just several times during clinical use and can obtain several data, use inconvenience for patient or measurand increase misery, operator, and several data that obtain respectively are not under the identical conditions increasing clinical diagnosis error.
The object of the invention is to provide a kind of probe that can detect a plurality of physiological parameters simultaneously, thereby reduces the measurand misery, and the mutual relation between different parameters relatively simultaneously is for experiment and medical diagnosis on disease provide more fully information.
Sensor probe of the present invention is made of conduit, and PH pick off, temperature sensor, pressure-sensitive air bag and airway are equipped with in catheter proximal end inside or conduit side, and wherein the PH pick off is by H
+Sensitive FET and Ag/Agcl reference electrode are formed, and temperature sensor is a critesistor.
This probe further describe for: described Ag/Agcl reference electrode is positioned at catheter tip, and electrode end surface protrudes in the conduit end face, and the duct wall perforate is loaded on the H in the conduit
+The responsive window of sensitive FET is exposed to outside the conduit by this hole.Described pressure-sensitive balloon ends is packaged in conduit outer wall, and conduit passes the pressure-sensitive air bag, the perforate of corresponding pressure-sensitive balloon positions, and air bag is by the airway conducting pressure in this hole and the conduit.Duct wall is opened aperture, and critesistor is positioned at this aperture.
Through over one hundred routine clinical experiment checking, very little to person under inspection's influence when this probe uses, probe inserts patient's esophagus stomach function regulating from nasal cavity, and patient can be free movable.Detect gastric pH value, pressure and temperature simultaneously, for clinical medicine provides a kind of new comprehensive detection by quantitative means.Gastric motility is learned research play very big progradation.
Fig. 1: be the profile of the present invention's probe;
Fig. 2: be probe of the present invention and detecting instrument connecting relation sketch map.
Existing accompanying drawings enforcement situation of the present invention.Ag/Agcl electrode 2 places conduit 1 top, and electrode end surface is given prominence to conduit end face 0.5mm, and duct wall is apart from the about 30mm of end face place's perforate, H
+The responsive window of sensitive FET 3 is exposed to outside the conduit by this hole.Pressure-sensitive air bag 4 is centered close to apart from conduit end face 60mm place, and the air bag diameter is 5.6mm during gas injection not, 8mm after the gas injection.Duct wall has aperture apart from the about 15mm of end face place, and critesistor 6 is positioned at this aperture, and is positioned at the plane tangent with the conduit cylindrical.Airway 5, reference electrode lead-in wire, H
+Sensitive FET lead-in wire, critesistor lead-in wire are filled element in the conduit with encapsulation with silica gel and are fixed by guiding detecting instrument in the conduit into.Probe conduit external diameter 4.5mm, length is greater than 1.5m, and probe is obtained various information in person under inspection's body, via micro-processor controlled PH transducing circuit, pressure transducer, temperature transducing circuit in the detecting instrument, become required data, is shown or is printed by instrument.
