ECG printing components

Abstract

The invention provides an electrocardiograph printing assembly. According to the electrocardiograph printing assembly, a rubber roller is arranged between the head and tail of a cabin body, and therefore, the paper feeding stroke of two ends of folded thermal sensitive paper can be reduced, and the deviation of the thermal sensitive paper can be avoided; the tail of a front paper guide plate and the head of a rear paper guide are set to be curved surfaces, and therefore, the thermal sensitive paper can be guided to enter a gap between the rubber roller and a thermal printing head, and the deviation of the thermal sensitive paper can be automatically corrected; the head of the front paper guide plate and the tail of the rear paper guide plate are set to be warped surfaces, and therefore, adjacent two pieces of thermal sensitive paper have a larger turning space when being fed, and the deviation of the thermal sensitive paper can be prevented.

Description

Technical field [0001] The invention relates to the field of electrocardiographs, in particular to a printing component of an electrocardiograph. Background technique [0002] The electrocardiogram function can automatically record the bioelectric signals generated by the myocardium when the heart is active. It is a medical electronic instrument commonly used in clinical diagnosis and scientific research. [0003] The electrocardiograph includes an input part, an amplifying part, a control circuit, a display part, a recording part, and a power supply part. The recorder is the tracing element of the electrocardiograph. For analog electrocardiographs, the recorders used in the early days were mostly moving coil recorders with disc springs returning to zero torque. After the 1990s, position feedback recorders were often used. At present, the commonly used digital electrocardiograph, the recorder is a thermal or dot matrix printer, by heating the semiconductor heating points sintered ...

AI Technical Summary

Problems solved by technology

In the past, roll paper was used for thermal paper, but now there is thermal paper in the form of folding back and forth. After the head of the thermal paper enters the printing gap between the roller and the print head, the tail is connected to the head of the next thermal paper. It is far away from the printing gap between the roller and the print head, and the stroke is long, so that it is easy to have the problem of deviation of the thermal paper during the printing process
