Definitions
- the invention is available for medical devices and devices with a wide range of medical problems. th level of technology
- the inventive invention also relates to equipment and 25 devices for measuring the variability of the heart rate.
- the basic methods for measuring the parameters of the CCC are electric power plants (electric power plants) and plethism (PG).
- Electric power is a measurement of electric field caused by electrical activity of the heart, and this means that the battery is used to measure electrical energy.
- a change in the voltage caused by the electric voltage at a time is called an electric drive.
- Plethism is a measure
- plethism 20 DEFINITION of the volume of pressure and compression of the heart. Changing the volume of space at a time is called plethism.
- the simplest method of plethism is opto-plethism (FPG), and in turn, this is a direct result of the accidental process. This light is partially dispersed and
- Taxes of the Invention The above-mentioned technical solutions are described, in particular, in 113 pages. ⁇ 3.980.075, ⁇ ⁇ réelle ⁇ ⁇ 5.397.774, ⁇ ⁇ réelle ⁇ . 5.4 ⁇ 5.423.322 and ⁇ ⁇ réelle ⁇ . ⁇ 5.632.272. However, not one of the above patents does not accept the installation
- the device does not disrupt the high diagnostic level without replacing the cassette, as well as the interruption of
- This property is the inability to remove electrical components that are compatible with or are susceptible to interference with systems (systems) without any interference with the device. Indeed, when removing an EHG, we need an electric patient contact with
- the method of the FPG is due to the above disadvantages, t. ⁇ . It does not require the presence of an electric contact between the patient and the computer and the special treatment of the patient (the patient is not treated at all).
- the device includes a number of other electrical and functional units: modules, a demodulator, an analog-to-digital converter and a signal processor. Relations with external devices ⁇ are not provided. At least these devices and the method is the closest to the present invention.
- the invention is notable for the substantial number of particularities of the analogs and the type. An essential distinction is the possibility of the use of the relevant inventive device in combination with conventional devices,
- the devices for measuring the parameters of the CCC can be omnipotent in the case of
- the main task, to solve the problem, is the claimed invention, which is a significant reduction in the energy consumed.
- the main input is separated by the necessity of setting the isolation between the amplifier and the constant output current with a high gain of 5,000 for amplification (using a gain of 5 for the signal) In such a way, there is no lack of a reliable connection, which increases the stability of the work (the accuracy and the result of the work are reduced).
- the process part of the BES receives both signal, pulse and pulse pulses, measures their duration and short-circuited components.
- the relative value which is further and is processed, corresponds to the signal pulse in the absence of
- the essence of the invention is as a result of filtering (or smoothing) the method of accumulation of a given number of registration paths.
- filtering or smoothing
- the first value of the measured value and is the sum of all elements of the array.
- the next value is determined by adding to the sum of the next value of the registration line and the simultaneous subtraction of the first element of the array.
- the new value of the registration flow replaces the subtracted element in the array.
- the quantization process corresponds to the process of following the impulses of the measuring generator. In general, if there is once a change in the signal signal pack (stored in the memory), the filtering process will be silent.
- BES is used on a commercially available computer; for the implementation of the invention, a compatible computer with a process model of at least 386 and a free S 1 or 2 is required.
- the device used for the implementation of the declared method includes the sequentially connected signal processor, the amplifier, and the processor is used for this 12
- WATER OUTPUT the module is connected to the process, which converts the SHI signal into a digital signal, which is filtered after the processing is processed.
- the block diagram also illustrates the obligation and consequence of the majority of the operations carried out in connection with the application of the claimed.
- a user-friendly embodiment of the device according to the claimed invention is shown in the block diagram of the attached device.
- the device s operating part ( ⁇ ) 3, including the variable signal amplifier 3.1, amplifier and filters 3.2, the electromechanical control unit 3.3, is variable
- the product package includes a specially designed disk with 60 KB bytes of information.
- the electronic control unit is implemented using modern
- the device was designed to exit the infrared sensor radiation.
- the indicated response to the patient places the palm of the hand in the palm of the hand, in particular the base of the heart; ⁇ and 14
- disk and modified mouse is 40 ⁇ 45 $ ⁇ . With a serial release, the indicated capacity will be reduced.
- the claimed inventions in the scope of the invention are devices and devices that are actively operated with the help of
