Adjustable Coiled Leadwire for ECG Monitoring

The leadwire incorporates a telescoping mechanism with coiled wire that can dynamically adjust its length. The wire extends from a compact coiled state to a fully extended state, allowing the leadwire to adapt its length based on the specific patient size and monitoring requirements, thereby preventing entanglement while maintaining compatibility across different patient populations.

The leadwire system changes the physical parameter of length from a fixed value to a variable range. By providing a mechanism that allows the leadwire to extend between minimum and maximum lengths, the system optimizes the length parameter for each specific application, eliminating the harmful effects of excessive length while ensuring adequate reach for all patient sizes.

The telescoping leadwire mechanism enables dynamic adjustment of wire length, allowing clinicians to extend the wire only to the necessary minimum length required for connection. This minimizes the conductive path length, thereby reducing electromagnetic interference and electrical noise while maintaining the ability to connect to all patient positions.

By changing the length parameter from excessive fixed length to optimized variable length, the system reduces the antenna effect and electrical noise generation. The leadwire extends only to the required length, minimizing parasitic capacitance and inductance that would otherwise increase with excessive wire length.

The telescoping mechanism incorporates a coiled wire design that can be manufactured using standard wire forming techniques. The coil structure is created by winding wire around a mandrel to a specified diameter and pitch, which is a well-established manufacturing process. This maintains manufacturing simplicity while enabling dynamic length adjustment for patient-specific optimization.

The leadwire is segmented into a coiled portion and straight end portions. The coiled segment provides the telescoping functionality while the end portions maintain standard connector interfaces. This segmentation allows the complex telescoping feature to be manufactured separately and assembled into the standard leadwire structure, preserving manufacturing ease.

The telescoping leadwire provides a dynamic length adjustment mechanism that allows the wire to extend from a compact coiled state to a fully extended state. This enables the leadwire to reach all patient positions when extended, while remaining compact and non-entangling in its coiled state during transport and storage.

The coiled wire structure effectively nests the leadwire within itself, creating a compact configuration that minimizes space occupation and prevents entanglement. When extension is required, the wire uncoils to provide the necessary reach, embodying the nesting principle that allows the same structure to occupy different effective volumes based on operational requirements.
