Vynález rieši zapoj enie automatickéhospúšťacieho a vybavovacieho obvodu ovláda-ného fázou EKG priebehu s vizualizáciounastavenej hodnoty s možnosťou generovaniavybavovacieho impulzu vo vopred zvolenomokamihu.The invention solves the connection of an automatic start and trip circuit controlled by the ECG waveform with visualization of the set value with the possibility of generating a pulse at a preselected time.

Pre potřeby záznamu ultrazvukových ob-rázkov dynamicky sa meniacich štruktúr ži-vých organizmov sa dnes používajú róznedruhy záznamových médií. Dokumentáciavo formě fotografie sa potom robí zastavenímzáznamu pri přehrávaní. Potřeba priebežnéhozáznamového zariadenia a prídavnej pamá-ťovej obrazovky v značnej miere zvyšuje zá-kladnu hodnotu celého zariadenia. Přitom preúčely dokumentácie sú zaujímavé len niekto-ré vybrané fázy sledovanej štruktúry, ktorémožno odvodit z okamžitej fázy elektrickéhoprejavu srdca, tj. EKG.For the purposes of recording ultrasound images of dynamically changing organisms of life, various types of recording media are used today. The documentary form of the photo is then made by stopping the recording while playing. The need for a continuous recording device and an additional memory screen greatly increases the basic value of the entire device. However, only some selected phases of the structure of interest that can be derived from the instantaneous phase of the electrical heart attack, ie ECG, are of interest for the documentation.

Uvedené riešenie umožňuje spúšťací a vy-bavovací obvod podl’a vynálezu, ktorého pod-statou je odvodenie spúšťacieho impulzu z R-vlny EKG priebehu s možnosťou jeho onesko-renia tak, že okamih zopnutia možno' lokali-zovat do ktorejkofvek fázy priebehu EKG.Polohu spúšťacieho impulzu na priebehu EKGmožno sledovat zvýrazněním na jeho zobra-zení.This solution enables the triggering circuit according to the invention to derive a trigger pulse from the R-wave ECG with the possibility of delaying it so that the moment of switching can be localized to any phase of the ECG. The position of the trigger pulse on the ECG can be monitored by highlighting it on its display.

Zabudovanie spúšťacieho obvodu do ultra-zvukových přístroj ov zobrazuj úcich v reálnom čase nám urfložní vykonávat fotografické zá-znamy pre potřeby dokumentácie vo vopredzvolenom okamihu, bez nutnosti záznamu namagnetické alebo iné záznamové médium.Incorporating a trigger circuit in real-time ultra-audio devices will provide us with the ability to perform photographic records for documentation at a pre-selected time, without the need to record a magnetic or other recording medium.

The signal sensed by the sensor 1 enters the amplifier 2 proceeds to the circuit for highlighting the trigger point 6 and simultaneously the R-wave detector. The output from the detector is fed to the delay member 5, from which the signal goes to the trigger point circuit 6 and to the control circuit 7, which controls the trip circuit 8. PriebehEKG is shown on the display unit 3 with the trigger point highlighted. .

Spozdenéimpulzy sú zároveň vedené do obvodu prezvýraznenie spúšťacieho bodu 6, v ktorom sa 201758The wiring according to the invention operates as follows: The sensed signal is processed in the R-wave detector 4 so that we receive pulses corresponding to the time R-wave of the ECG waveform at the output. The pulses thus formed are then passed through a delay member 5, which allows the delay of the output pulse to be steplessly or infinitely variable. The pulses detected in this way indicate that the control circuit 7 is switched on by the trigger circuit 8 being triggered. The trigger pulses are simultaneously routed to the trigger point highlighting circuit 6, in which 201758

Using the start block 9, the operator indicates the pulse for the next control circuit switch 7. used to control the triggering of a film camera when scanning one frame, or to synchronize other recordings. OBJECT Automatic triggering and tripping circuit controlled by the ECG waveform with visualization of the setpoint, characterized by the sensor (1) being connected to the amplifier (2), one output is connected by a circuit of the override of the trigger point (6), which is only connected to the display unit (3), in the apparatus for making ECG-dependent phased recordings, as well as controlling the switching circuits at the readings of the instantaneous values of the different physics depending on the phase of the ECG in the monitoring systems, etc. The brightness of the screen can also be controlled, allowing the selected phase to be highlighted in a dynamic record as well as to adjust the brightness for photographic purposes.
