  • the electrical signal and the filter circuit filter the electrical signal of the test subject detected by the electrode circuit, the amplification circuit amplifies the electrical signal output by the filter circuit, and the A/D converter amplifies the amplified electrical signal from the analog signal.
  • Step S5 The measurement is completed, waiting to be sent;
  • the display unit displays an indication that the measurement of the electrocardiographic waveform is completed, and prompts the subject to relax, thereby releasing the measurement posture, and waits for the reading instruction of the upper computer to send the electrocardiographic waveform to the upper computer; Step S6 is sent;
  • Step S7 Waiting for timeout
  • step S2 in order to save the power of the power supply, it is determined whether the time waiting for the measurement is timed out. If the timeout is exceeded, step S8 is performed, otherwise step S2 is continued to wait for step S8 to be turned off;

  • This embodiment describes in detail the program execution flow of the card-type ECG measuring instrument. After the measurement of the ECG waveform is completed, in the process of waiting to send the ECG waveform, the subject can choose to clear the current measurement data according to the actual situation.
  • the related technical solution increases the processing authority of the subject to measure the completed ECG waveform in time, so that the subject can quickly and autonomously screen more effective ECG waveforms for storage, which provides reliable for subsequent effective ECG analysis.

Abstract

L'invention concerne un instrument de mesure d'un électrocardiogramme, comprenant une carte de circuits imprimés (101), un support de corps principal (102) et une encapsulation arrière. La carte de circuits imprimés (101) est fixée sur le support de corps principal (102) au moyen de l'encapsulation arrière. La carte de circuits imprimés (101) comprend une électrode externe et un circuit de traitement, le circuit de traitement comprenant un circuit d'électrode qui est connecté à l'électrode externe ; et l'électrode externe comprenant une électrode tactile positive (108), une électrode tactile de feed-back arrière (104, 105) et une électrode tactile négative (109). L'électrode tactile positive (108) est connectée à une électrode positive du circuit d'électrode, l'électrode tactile négative (109) est connectée à une électrode négative du circuit d'électrode et l'électrode tactile de feed-back arrière (104, 105) est connectée à une électrode de feed-back du circuit d'électrode ; et le circuit d'électrode est utilisé pour détecter un signal électrique d'un patient en cours de mesure. L'instrument de mesure d'un électrocardiogramme est utilisé pour fournir un service de mesure de formes d'ondes électrocardiographique pour des patients qui ont besoin de la mesure de la forme d'onde électrocardiographique en raison de palpitations ou d'une polypnée, etc., à tout moment.
