Wrist Cradle - Wrist support for pregnancy-related carpal tunnel syndrome

This is a wearable wrist support device for discomfort including hand numbness, pain, and swelling during pregnancy. It integrates structural support, thermal relief, and hand training into a lightweight device designed for comfortable extended daily wear. Unlike common wrist braces that mainly immobilize the wrist, it uses a hand splint to control excessive wrist flexion and extension, keeping the wrist in a relatively relaxed mid-range position. It ensures necessary hand mobility, better adapting to frequent hand-use needs such as sleep, phone and computer use, painting, and daily gripping.
Functionally, it incorporates dual-mode hot and cold temperature control, providing gradual heating or cooling according to different discomfort conditions, and employs an automatic heat dissipation system to manage temperature variation during extended wear. The physical knob allows users to adjust directly without requiring a phone connection, easing nighttime and daily operation effort. The detachable massage ball extends resting support to voluntary grip training, enabling flexible switching between rest and hand activity.
Visually, it wraps the structural support in breathable knit fabric and utilizes a soft touch to avoid the uninviting feel of common medical braces. The splint and finger strap work together to maintain a secure fit. Such a modular, detachable combination also facilitates component maintenance and replacement, delivering a more well-rounded pregnancy hand support experience that balances comfort, portability, and sustained use.
