Description

Electrocardiogram chest electrode fixing device Technical Field The invention relates to the field of medical appliances, in particular to an electrocardiogram chest electrode fixing device which can realize accurate positioning, flexible adjustment and firm fixation of electrodes. Background At present, the chest lead electrode is mostly fixed on the chest skin of a patient by adopting a mode that the chest lead electrode is adsorbed on the chest skin of the patient, namely, the electrode is fixed on a chest preset acquisition point by negative pressure adsorption or adhesive adhesion of the electrode. The auxiliary fixing mode is that the elastic binding band is simply wound around the chest, and certain pressure is applied to the electrode through the binding band, so that the electrode displacement is reduced. In a pre-hospital emergency mobile vehicle-mounted scene, due to jolt and shake in the running process of a vehicle, the traditional chest lead electrode adsorption fixing mode is difficult to meet the stability requirement, the chest lead electrode adsorption mode is mostly used in clinical practice, electrode displacement is reduced only by hand-held auxiliary pressing of medical staff, and no special electrode positioning and sliding adjustment design exists. In the prior art, each electrode can be fixed at a preset point position only by means of adsorption, a matched rail type fixed carrier is not available, the relative positions between the electrodes cannot be flexibly adjusted according to the body type difference of a patient, and the degree of adhesion between the electrodes and the skin is completely dependent on the self adsorption force of the electrodes or the adhesion force of adhesive. The prior art lacks the adaptability design to different body type patients, and for special body type patients such as emaciation, obesity, old age, can't guarantee the effective laminating of electrode and skin, electrode position deviation standard acquisition point position influences the uniformity and the comparability of electrocardiogram waveform.
