Description
Technical field
The invention belongs to technical field of medical instruments, more particularly, relate to a kind of ECG electrode folder.
Background technology
At present, electrocardiogram is the conventional means of clinical diagnosis heart disease, and electrocardiogram has important effect to the diagnosis of cardiovascular disease.When making electrocardiogram; Need ECG electrode be clipped on people's the limbs (like wrist, ankle), and make the electrodes conduct sheet of ECG electrode folder and the skin surface of human body form excellent contact, like this; The electrodes conduct sheet just induces weak current from the skin surface of human body; And weak current flowed to electrocardiograph amplify hypermnesia, thereby form the electrocardiosignal of human body, according to these electrocardiosignaies just can the analyzing and diagnosing people cardiovascular disease.
When the electrocardiogram electrode holder is clipped in people's limbs; The electrodes conduct sheet of ECG electrode folder and the contact surface of skin surface exist certain contact impedance; And the contact impedance size between electrodes conduct sheet and the human body skin is directly connected to the power of the electrocardiosignal of electrocardiograph acquisition; Directly have influence on the amplitude of electrocardiosignal input and the size of noise, have influence on the Electrocardiographic accuracy of tracing quality and diagnosis at last.
Existing ECG electrode folder generally comprises train wheel bridge, lower plate, rotating shaft, torque spring, electrodes conduct sheet and lead; Train wheel bridge and lower plate can be installed in the rotating shaft each other rotationally; Train wheel bridge and lower plate are in the part at rotating shaft rear for grabbing the portion of pinching, and the part that train wheel bridge and lower plate are in rotating shaft the place ahead is a clamping part; Torque spring is enclosed within the rotating shaft; One end of torque spring and the portion of pinching of grabbing of train wheel bridge join; The portion of pinching of grabbing of the other end of torque spring and lower plate joins, under the effect of torque spring elastic force, and the clamping part clamping of the clamping part of train wheel bridge and lower plate or have the trend of mutual clamping; The electrodes conduct sheet is installed on the clamping part of train wheel bridge or lower plate, and the electrodes conduct sheet is electrically connected with electrocardiograph through lead.
In existing ECG electrode folder; Because the radian of its clamping part of train wheel bridge, the radian of its clamping part of lower plate immobilize, so, when the electrodes conduct sheet is installed on the clamping part of clamping plate in train wheel bridge and the lower plate; Distance between the clamping part of electrodes conduct sheet and another clamping plate also immobilizes; And people's limbs have size, fat or thin, adult and baby's difference, and in the time need carrying out Electrocardioscopy to the those who are investigated of slight of stature or baby, existing ECG electrode folder just can't be clamped those who are investigated's limbs well; Like this; Electrodes conduct sheet on the clamping plate just can not form excellent contact with those who are investigated's limb skin, thereby causes contact impedance excessive, makes that the input range of electrocardiosignal is little, noise big, the output waveform distortion; Thereby can not write down the Electrocardiographic variation of those who are investigated exactly, have influence on the Electrocardiographic accuracy of tracing quality and diagnosis.
Summary of the invention
