Patent Innovations: Anti-Tangling and Swing-Proof Medical Device Wiring Harnesses

Two recent patent filings highlight ongoing innovation in medical device wiring harness design:

Meiyin Health (Shanghai) received a patent for a medical device-specific wiring harness designed to prevent lead wire tangling and enable individual replacement of faulty lead wires. The harness features an integrated head with pluggable patient-side lead wires, providing structural support to prevent cross-tangling while allowing isolated replacement of defective leads.

Sonoscape Medical (Shenzhen) received a patent for an optoelectronic composite cable that enhances swing performance and protects electronic wires. The design incorporates:

• Armored optical fiber with a protective tube

• Woven fiber layer wrapped around the armored tube

• Protective tape layer

• Multiple electronic wires distributed circumferentially

• Outer protective layer

The design prevents electronic wires from being damaged by the sharp edges of the armored tube, controls the ductility of the armor, prevents cable deformation during cutting, and enhances overall swing performance.
