Description

A device for recording and correcting wave processes of bioobjects includes a signal sensor, a signal processor unit, a storage medium with standards, as well as a unit for comparing the recorded signal with standards and a block of the feedback signal generator, the functions of which are performed by a computer. Standards are presented in electronic digital form on flash cards, optical disks, HDD, etc. The signal processor block includes inputs for sensors, a switch, an amplifier, a low-noise voltage regulator, a reversible analog-to-digital converter, and a USB port for connecting to a computer. In this case, the signal from the sensor through the switch is fed to the amplifier, then to the analog-to-digital converter, and then the digitized signal is fed to the computer to the unit for comparing the signal with the standard. In the correction mode, the signal passes in the reverse order from the block of the feedback generator to the sensor operating in this case as a radiator.

The present utility model relates to medicine, including veterinary medicine, and to medical technology. This utility model is intended for medical diagnostics according to the reference spectral-dynamic markers and for highly specific spectral-dynamic correction of wave processes of a biological object.

Closest to the proposed utility model is a device according to the patent for utility model "Device for recording and correction of wave processes."

A device for recording and correcting wave processes includes a sensor, a broadband high-sensitivity amplifier, a reversible analog-to-digital converter, as well as a unit for comparing the recorded wave signal with the standards and the block of the feedback signal generator, the functions of which are performed by the computer, and an external information carrier with the bases of the standards, characterized in that the broadband high-sensitivity amplifier and a reversible analog-to-digital converter are combined into a separate signal processor unit, which ensures AET recording and correction of wave propagation in the frequency range from 22 Hz to 22 kHz.

[Declaration patent of Ukraine for invention No. 19808, IPC _ (2006) A61N 5/02 A61B 5/04 A61H 39 / 02_; Publ. 12/15/2006_.].

The disadvantages of the prototype are not sufficiently low level of the noise of the amplifier, which affects the signal-to-noise ratio, as well as the lack of the possibility of using single-pole and two-pole sensors.

The objectives of this utility model are to improve the recording quality of the wave process by improving the signal-to-noise ratio at the signal gain level. The inventive device, like the prototype, contains a sensor, a signal processor unit, a comparison unit, a feedback signal generator unit and a storage medium with standards.

According to the proposed utility model, a low noise amplifier power regulator and a switch are additionally introduced into the signal processor unit.

In the proposed device, the recorded signal from the sensor is fed to the input of the signal processor unit, then to the switch and then to the input of the amplifier. The amplified signal is fed to the input of a reversible analog-to-digital converter, and the already digitized signal is fed to the computer at the input of the comparison unit. The comparison is based on the wave years of the conversion of the spectrum of the input signal and the spectrum of the standard. The return signal is generated in the reverse order based on the reference.

The introduction of additional structural components, namely, a low-noise power supply stabilizer of the amplifier and switch, into the processor unit allowed us to solve the problems posed above.

In figure 1. schematically shows the proposed device.

The inventive device for recording and correcting wave processes of biological objects 1 includes a sensor 2, a signal processor unit 8, which includes a switch 3, an amplifier 4, a reversible analog-to-digital converter 5, a USB port 6, a low-noise power supply stabilizer for an amplifier 7, a computer 12 with an operating system 11, in the framework of which a comparison block and a block of a generator of feedback signals are implemented, as well as a storage medium with records of reference diagnostic markers 13.

The proposed device operates as follows. A contact is made (directly or through a tissue) of the sensor 2 with the region of interest of the patient's body. Typically, the patient is invited to take the sensor in his hand. The sound wave electromagnetic signal (22 Hz - 22 KHz) is fed to the input of the signal processor unit 8 and is fed through switch 3 to a high-bandwidth high-sensitivity amplifier 4, which is powered from the USB port 6 through a low-noise voltage regulator 7, which improves the signal / noise. The amplified signal is fed to the input of a reversible analog-to-digital converter. The digitized signal via USB port 6 enters the computer 12 at the input of the comparison unit 9, which compares the wavelet years of the spectrogram of the input signal and the reference diagnostic marker previously selected from the information carrier 13, thereby recognizing the image of the reference diagnostic marker in the spectral-dynamic structure of the input signal from the patient’s body 1. The doctor performs the diagnosis on a set of recognized markers. Based on the diagnostic results, if there are medical indications, the doctor selects a spectral-dynamic standard for performing wave correction with a healing, prophylactic or therapeutic purpose, and also chooses one of two correction modes - resonance mode (direct signal) or compensation mode (inverted signal). The digital signal of the selected standard and mode from the block of the feedback signal generator 10 through the USB port 6 is fed to the input of a reversible analog-to-digital converter 5, where it undergoes digital-to-analog conversion. Next, the analog signal is fed to the input of amplifier 4, where it is amplified and supplied through sensor 2 to the field of patient 1.
