After loading the operating system and self-test computer doctor selects on the screen (in accordance with tekstovoi information) using marker-pointer of the apparatus with which it will work. If you select a remote device in accordance with the specified numbers (Fig. 2), the singleton system (3) will correspond to the ultrasonic nebulizer or physical therapy, or surgical ultrasonic device that runs on radiation (depending on the radiation head and the specified powerfully-, cardio or Ophthalmoscope depending on the type singleton sensor, a multipart system receiver 5 will correspond to the ultrasound scanner, depending on the selected sensor type, singleton sectoral system receiver 7 will correspond to a sector scanner, microphone, pressure sensor 8 will correspond to a device for visualization of cardiac murmurs and pressure (venous or arterial) depending on the selected type of sensor, cable ECG lead 9 is connected to the corresponding multi-channel electrocardiograph, and cable EEG 10 - K the electroencephalograph, the universal docking station 11 is connected to the device, to extend the functionality of the processing of biological information using a commercially available ultrasound scanners, electrocardiographs, electroencephalographs, and other medical diagnostic equipment. All help messages on the use of the selected device are displayed on the screen of the video display of the computer in the form of text information, and the execution of all commands by pressing the corresponding keys on the keyboard when prompted by the computer.

The device allow) and low weight.

Comparative analyses obtained using a universal computer diagnostic system (UCBC) survey data showed high accuracy and information content, and use in the same enclosure multiple diagnostic and therapeutic ultrasonic physiotherapy and electrophotographic apparatus greatly simplifies and facilitates the work of the physician in the diagnosis of the patient during one visit.

Ultrasonic computerized diagnostic system that includes the computer, monitor, keyboard, printer and standard external devices, including the singleton system receiver, cardiointervals with standard cable lead electrocardiogram, characterized in that the standard remote devices further include a singleton system, multi-system receiver, singleton sectoral system receiver, microphone and receiver noise with a pressure sensor, the cable leads of EEG and encephaloceles, and universal docking station and an interface for connection of additional medical devices, and between computers and external devices connection is fast memory, connected to the computer.

SUBSTANCE: according to 4-point scale one should evaluate the state of 10 clinical, hemodynamic and instrumental values in patients: patient's skin by detecting its color and moisture; hemodynamic values: heart rate, systolic arterial pressure, central venous pressure, shock index; central nervous system by studying the value of Glasgow scale; respiratory system - the frequency of respiratory movements and blood saturation; cardio-vascular system - myocardial necessity in oxygen. Each value has its own point, moreover, 0 points corresponds to that fact that the index under inspection is within age standard, 1 point - when physiological parameters at rest are different against the standard, but their functions are compensated by organs of one or two systems, 2 points - compensation is kept due to alterations in more than 2 systems and it reaches its peak, 3 points correspond to adaptation failure or affected function of one or several systems, and the sum of points being 0-4 in patients one should diagnose the absence of hemorrhagic shock, at 5-9 points - the severity of hemorrhagic shock corresponds to degree I, at 10-19 points - to degree II, at 20 points and more - to degree III.
