What types of recorders can be used in medical electrocardiogram machine

For medical places, in many cases, it is necessary to use a good reputation of medical electrocardiogram machine, so as to better analyze the human heart activity according to the waveform displayed by the electrocardiogram machine, and also in the clinical diagnosis of heart disease and other diseases, this equipment is more essential. As a very important part of the equipment, the recorder can be divided into a variety of different types. The following medical electrocardiogram machine can be used which types of recorder this problem monitor manufacturers do a brief analysis:

1, moving coil recorder

Economy as a medical electrocardiogram and very important recording components, especially for the analog electrocardiogram machine, early often used various forms of recorder products, which is mainly composed of magnetic steel fixed magnetic circuit and a rotating coil. When the electrocardiogram and power amplifier signal output, the output signal can be added to the recorder coil, indirectly, there should be a fixed record ratio, so you can use the coil driven recording pen on the recording paper to trace out the electrocardiogram waveform.

2. Position feedback recorder

Position feedback recorder is a kind of special recorder without mechanical return to zero spring. This recorder can play the role of return to zero spring in special electronic circuit. When the machine is powered off, the pen of the position feedback recorder can be flipped at will.

3, lattice thermal recorder

Dot matrix thermal sensitive recorder is also a more commonly used type of recorder for medical electrocardiogram ‍, this recorder is mainly used to heat the semiconductor sintered on the ceramic substrate to add hot, so as to heat the color of the thermal paper hot out graphics and characters.

The content of the above several aspects comprehensively medical electrocardiogram machine ‍ can adopt a variety of different types of recorder to record, from this perspective, this part of the electrocardiogram machine there is a certain difference, so the people to choose a reliable medical electrocardiogram machine ‍ products, also, recorder and so on part of it is necessary for its use and response, there is a certain understanding to the working principle of Help to help yourself to choose more trustworthy medical electrocardiogram machine ‍ products.Meilun
