AI Technical Summary

Technical Problem

The connection between the electrode pads and the leads of the electrocardiogram monitor is prone to separation and detachment due to changes in the patient's position or unconscious pulling, resulting in the disappearance of the electrocardiogram waveform or signal distortion, which increases the workload of nurses.

Method used

Design an electrode sheet comprising an electrode connector and a constraint component. The conductor connector is constrained in multiple directions by a constraint cavity and various limiting structures (such as elastic ropes, clamps, and limiting grooves) to ensure a stable connection between the conductor connector and the electrode sheet.

Benefits of technology

It significantly reduces the probability of lead dislodgement, ensures the continuity and accuracy of ECG monitoring, reduces repetitive operations for medical staff, and lowers labor intensity.
