Description

 The invention relates to medical equipment and is intended for ultrasound and electrographic diagnostics of human internal organs.

 As a prototype, a diagnostic ultrasonic installation (US 5513640 A), Kabushiki Kaisha Toshiba, A 61 B 8/00, 05/07/96, containing a computer, a monitor, a keyboard, a printing device and standard external devices including a single-element piezo-receiver and cardio interface with standard ECG lead cable. This installation is a structurally complete device that has specific diagnostic goals - a non-invasive examination of the internal organs of a person by means of an ultrasound section and registration of biopotentials of the heart.

 The disadvantage of this device is the high cost, narrow specialization of the functions performed.

 The aim of the invention is the creation of a simple, cheap, reliable, multifunctional medical device based on a standard computer.

 This goal is achieved by the fact that in an ultrasonic computer diagnostic system consisting of a computer, a monitor, a keyboard, a printing device and standard external devices, including a single-element piezoelectric transducer - receiver, a cardio interface with a standard cable of electrocardiogram leads (ECG), standard external devices additionally include a single-element piezoelectric transducer , multi-element piezoelectric radiator-receiver, single-element sector piezoelectric emitter-receiver, microphone and noise receiver with sensor pressure cable, leads of electroencephalograms (EEG) and encephalointerface, as well as a universal docking station and interface for connecting additional medical devices, while an amplifier interface consisting of multiplexers, an amplifier, an analog-to-digital converter (ADC) is connected between computers and external devices a quick memory module connected to a computer.

 In FIG. 1 shows a block diagram of a device.

 In FIG. 2 shows a block diagram of an electronic unit of a device and external devices.

 An ultrasound computer diagnostic system comprises (see FIG. 1) a computer 1, a monitor 2, a keyboard 4, a printing device 3, an electronic unit 5, and standard external devices 6, as described in more detail in FIG. 2, namely, a single-element piezo emitter-receiver 4, a cardio interface with a standard ECG lead cable 9, a single-element piezo emitter 3, a multi-element piezo-emitter 5, a single-element sector piezo-emitter-7, a microphone and a noise receiver with a pressure sensor 8, Encephalointerface 10, a universal docking station 11 and an interface for connecting additional medical devices, while an amplifier-interface 2 (Fig. 2), consisting of multifunction devices, is connected between computers and external devices typelexers, amplifier, ADC and fast memory module 1 (Fig. 2) connected to the computer 1 (Fig. 1). The quick memory module 1 transmits biological information from the patient in the form of digital codes to a basic standard computer for its subsequent processing. The electronic unit (5) (Fig. 1) is located in the computer and is controlled by a specially developed program. All ultrasonic piezo emitters-receivers have ultrasonic transceivers, with the exception of a single-element piezo emitter, which has only an ultrasonic transmitter. A single-element piezoelectric sector receiver has control.

 The device operates as follows. The apparatus is turned on as a normal computer. After loading the operating system and self-checking the computer, the doctor selects on the monitor screen (in accordance with the text information) with the help of a marker pointer the device with which he will work. If you select external devices in accordance with the indicated numbers (Fig. 2), then a single-element piezoelectric transducer (3) will correspond to an ultrasonic inhaler or a physiotherapeutic or surgical ultrasonic apparatus that operates on radiation (depending on the used emitting head and the set ultrasonic radiation power) , a single-element piezo-receiver 4 will correspond to an encephalo-, cardio- or ophthalmoscope depending on the type of single-element sensor used, multi-element the ultrasound scanner will correspond to the new piezo-emitter receiver 5 depending on the type of sensor selected, the sector scanner will correspond to the single-element piezoelectric receiver-sector 7, and the device for visualizing heart sounds and pressure (venous or arterial) will correspond to the microphone of the pressure sensor 8 depending on the selected type of sensor, the cable of the ECG leads 9 is connected to the corresponding multi-channel electrocardiograph, and the cable of the EEG 10 leads is connected to the electroencephalograph, The personal docking unit 11 is connected to a device that allows expanding the capabilities of processing biological information using commercially available ultrasound scanners, electrocardiographs, electroencephalographs, and other medical diagnostic devices. All help messages on the usage order of the selected device are displayed on the screen of the computer video terminal in the form of text information, and all commands are executed by pressing the corresponding keys on the keyboard at the computer prompt.

 The device has versatility and versatility, the use of standard peripheral devices (sensors) and low weight.

 Comparative analyzes of the survey data obtained using the universal computer diagnostic system (UKDS) showed their high reliability and information content, and the use of several diagnostic and therapeutic physiotherapeutic ultrasound and electrographic devices in one building significantly simplifies and facilitates the work of the doctor when diagnosing a patient in one visit.
