Androdioecious

Androdioecious - method telemetry study of some aspects of the digestive tract. The principle of androdioecious is that miniature radio transmitter (Radioprylad, the radiosonde), swallowed by the patient, reports during the passage through the digestive tract on radio receiver information about different sides of this tract. Installation for androdioecious consists of a radio transmitter, the receiving antenna, a special receiver and recording part.

radiobilogy
Radiobilogy for research temperatures (1), pressure (2) and sour (3). Increased twice.

Radioprylad consists of a sensor, a generator of electromagnetic waves of high frequency and power supply. External influence on the sensor change its electrical properties, which leads to changes in the electromagnetic waves emitted by the generator. Radio receiver absorbs the waves by antennas and submits to the registration part. Created radiobilogy to determine the concentration of hydrogen ions, pressure and temperature (Fig.). The length of radiobiol 10 -12 mm, diameter 7-8 mm

Androdioecious is a method radio research some of the manifestations of the activity of the digestive tract.
The principle of androdioecious is that using a miniature radio transmitter (radiobiol, andardized), introduced in the gastrointestinal tract, and radio receiving devices in the laboratory register certain physiological, physical and chemical phenomena.
Installation for androdioecious consists of a radio transmitter, the receiving antenna, radio special design and device for registration of the investigated phenomenon (Fig. 1). Radioprylad consists of a sensor directly perceiving changes in the analyzed parameter, generator of electromagnetic waves of high frequency and power supply. Its length 11-20 mm, diameter-8 mm, It is easy proglatavetsa and passes freely throughout the digestive tract. Under the influence of external factors on the sensor radiobilogy changes electromotive force on the sensor electrodes or its electrical parameters (capacitance or inductance), which causes frequency modulation generated by the transmitter of electromagnetic oscillations. Generators radiobiol operate in the frequency band of 300 - 450 kHz or 1800-2000 kHz. By the antenna in the vicinity of the test or put on him, radio receiver perceives radiated by a transmitter fluctuations. Reinforced fluctuations demodulators frequency discriminator so that there is a low-frequency component of the signal, which characterizes the changes of the investigated physiological process. Created andardized (radiobilogy) to determine the concentration of hydrogen ions, pressure and temperature (Fig. 2). Attempts development radiobiol that transmit information about the presence of blood in the digestive tract, enzymatic activity, the pressure of oxygen and the amount of ionizing radiation.
Radiobilogy for measuring pressure detect the change in the stomach and intestines in the range from 0 to 200 cm waters. century (Fig. 3). The pressure sensor is moving ferrite core, which is the core coil-inductance, included in the circuit of the generator. As a temperature sensor in Radioprylad apply ceramic capacitor (variant temperature coefficient. Radioprylad for pH measurement is based on the principle electrometric measurements of the concentration of hydrogen ions (Fig. 4). Designed also radiobilogy to help identify two indicators of functions of the digestive tract: pH and pressure.
Compare the reading of androdioecious with results obtained by other methods, found in animal experiments complete coincidence. The advantage of androdioecious is that it is not associated with any effects on the body that violate normal digestive processes.
In connection with the free mobility of radiobilogy of androdioecious allows to observe the processes occurring in all of the gastrointestinal tract (Fig. 5). In the study of man is sometimes necessary to attach to Radioprylad thread, delaying its promotion, for example from the stomach to the duodenum.
The location of radiobilogy can be produced by radiography or by radiotelegraphy. Installation for radiotelegraphy allows you to determine the location and speed of radiobiol. Cm. Sensors, Telemetry, Electronic amplifiers.
