AI Technical Summary
Existing direct cardiac compression devices are prone to premature failure during use, cannot effectively follow the natural torsional movements of the heart, and cannot directly compress the heart, resulting in excessive mechanical load on the device and affecting its service life.
Design a device comprising multiple passive chambers and inflatable active airbags, the airbags tapering from the opening to the tip and connected by independent inflation and support structures to avoid tension on adjacent airbags, combined with a frame and containment layer to reduce mechanical load and adapt to the natural movement of the heart.
It extends the lifespan of the device, effectively assists cardiac function in the short and long term, adapts to the natural torsional motion of the heart, reduces mechanical load, and improves the durability of the device.
