Matched signal collection suction ball of novel ECG machine

Abstract

The invention discloses a matched signal collection suction ball of a novel ECG machine and belongs to the technical field of medical appliances. The signal collection suction ball comprises a soft ball, wherein a metal side skirt is fixedly connected to the bottom of the soft ball, the soft ball communicates with inside of the metal side skirt, a rubber side skirt is fixedly connected to the outer edge of the bottom of the metal side skirt, a fixation ring is fixedly connected on the outer side wall of the metal side skirt and a metal interface is inserted in the fixation ring, and the metalinterface is fixedly connected to one end of a wire. An internal metal patch can get close to skin under effects of a spring on a metal side skirt support, elastic force of the spring is very small and only applied to fitting with the surface of a patient, the elastic force of the spring is smaller than suction force of the soft ball, the whole body is prevented from being ejected by the spring and then falling down, the rubber side skirt is used for improving problems in easy stripping, red marks and plaques, the spring is used for solving the problem that electric signal collection is unstable, and the wire and the external interface are used for solving the problem that existing wires are too hard.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a novel electrocardiograph matching signal collection suction ball. Background technique [0002] The electrocardiogram function can automatically record the bioelectrical signals generated by the myocardial excitement when the heart is active. It is a medical electronic instrument commonly used in clinical diagnosis and scientific research. Before the heart beats, the myocardium is first excited. The tissue conducts to each part. Since the tissues of each part of the body are different, and the distance between each part and the heart is different, various parts of the human body surface show different potential changes. The surface potential generated by the electrical activity in the human heart The relationship with time is called an ECG. [0003] At present, patients need to use electrocardiogram devices when performing testing. Most of the existing elec...

Problems solved by technology

[0003] At present, patients need to use an electrocardiogram device when performing testing. Most of the existing electrocardiogram instruments use suction balls to be adsorbed on the patient's chest, so as to monitor the patient's ECG in real time, but they are prone to fall off in thinner patients. , and there will be red marks and plaques in the place where the patient's chest is sucked, and there are problems of unstable electrical signal collection and too strong wire connection hardness
