Abstract
The present invention relates to a stomach magnetic apparatus for diagnosis of gastric functional disease, which is characterized by that a magnetic tracer agent is added to test meal for diagnosis, and it utilizes an excitation coil mounted on the test bed to magnetize said tracer agent, then utilizes the magnetic sensor to detect the relative change of gastric magnetic field. The bed surface of said stomach magnetic apparatus can be moved formward and backward, rightward and leftware and upward and downward. Two excitation coils are respectively placed over bed surface and under the bed surface, and the magnetic sensor is mounted on the machine frame over the bed. The invention can be used for diagnosis of gastric functional disease.
Description
The invention belongs to magnetic gastrosis diagnosinig instrument that medical domain is used, that can diagnose the functional disease of stomach.
For the diagnosis of stomach functional disease, use gastric emptying half-time usually, promptly gastric is eaten quantity of food and is reduced half required time as a token of.The existing method of measuring gastric emptying has: x-ray method is to allow the patient take barium sulfate, measures gastric emptying with X ray; Tremie method is to extract liquid test-meal mensuration emptying in the stomach repeatedly with conduit; The scintigraphy method is that the isotope of technetium and indium is sneaked in the test-meal, regularly collects ray data by gammacamera, determines gastric emptying half-time; The time real ultrasonic method be regularly to measure the stomach-ultrasonography image with B ultrasonic, show gastric test-meal evacuation procedure.Though above method all has certain effect, owing to or certain radiolesion is arranged or bring bigger misery or, bring difficulty to clinical practice because of the expense used is relatively more expensive to the patient.
The objective of the invention is to develop at the deficiencies in the prior art, is magnetic gastrosis diagnosinig instrument core, that can check the stomach functional disease with magnetic spike detection technique.
The present invention is achieved by the following measures.Magnetic gastrosis diagnosinig instrument is to utilize gastric emptying half-time to diagnose the instrument of stomach functional disease, promptly adds special magnetic tracer (Fe in test-meal
3O
4), after the pulse magnetic field magnetisation, adopt the weak magnetic measurement technology, measure the stomach table magnetic field that the emptying with test-meal decays.According to the relative variation in stomach magnetic field relation curve, determine gastric emptying half-time with emptying time.Magnetic gastrosis diagnosinig instrument of the present invention is made up of frame, test envelope, magnet exciting coil, Magnetic Sensor and computer system, it is characterized in that: the bed surface of test envelope is arranged on the lathe bed, is connected with lathe bed by longitudinal moving device; Be provided with the bed surface horizontal mobile device on the lathe bed simultaneously; Be provided with lowering or hoisting gear below the lathe bed; Two magnet exciting coils be separately positioned on below the lathe bed and the frame above the lathe bed on; Magnetic Sensor is arranged on the frame of lathe bed top; The control section of bed surface mobile device, magnet exciting coil and Magnetic Sensor all is connected with computer system.For making things convenient for tester's bunk bed, the junction of magnet exciting coil and frame is provided with magnet exciting coil position travel mechanism.Used Magnetic Sensor is highly sensitive low-intensity magnetic field detecting instrument, adopts bridge-type to detect the circuit of magnetic field peak value, and has that range automaticallyes switch and to the auto compensatng circuit of environmental magnetic field; Magnetic Sensor is connected with frame by micromatic setting.
Use the method for testing of magnetic gastrosis diagnosinig instrument to be, before test, the experimenter is the mixing test-meal of food sanitation standard on an empty stomach, adds special Fe in the test-meal
3O
4The magnetic tracer is promptly lain on the back after the food on the test envelope of magnetic gastrosis diagnosinig instrument, and after the pulse magnetic field magnetisation, test stomach table magnetic field is with the relation of emptying time.Survey once per half an hour, the data of measuring are deposited in the computer, and the gastric emptying curve that draws after treatment, and calculate gastric emptying half-time, as the foundation that diagnoses the illness.
Advantage of the present invention is: utilize the management of computer realization measuring process and adopt advanced weak magnetic measurement technology, test data is accurate, dependable performance, and is multiple functional, easy and simple to handle.This product does not have injury, no wound to human body, easily is that patient and hospital accept.
Accompanying drawing is the structural representation of excitation of the present invention and test section, and (1) is lathe bed among the figure; (2) be lowering or hoisting gear; (3) be the bed surface mobile device; (4) be bed surface; (5) be magnet exciting coil; (6) be frame; (7) be Magnetic Sensor.
Existing accompanying drawings one embodiment of the present of invention.Bed surface (4) is placed on the lathe bed (1) by bed surface mobile device (3), lowering or hoisting gear (2) is below lathe bed (1), magnet exciting coil (5) is below lathe bed (1), and another magnet exciting coil (can, do not draw among the figure) and Magnetic Sensor (7) are installed on the frame (6) of lathe bed top.Before the test, the experimenter eats and contains the tracer Fe that is magnetic
3O
4Test-meal, on the bed surface of the test envelope of lying on the back, make experimenter " at the bottom of the stomach " be positioned at the center of magnet exciting coil, carry out impulse magnetization after, horizontal mobile bed surface is positioned under the Magnetic Sensor experimenter " at the bottom of the stomach " and detects.The data of repeated detection are deposited in the computer, the gastric emptying curve that draws after treatment, and calculate gastric emptying half-time.
