AI Technical Summary
Technical Problem
Traditional liquid feeding aids cannot effectively control the speed of propulsion when pushing viscous liquid food, causing pain to patients, and the friction locking structure is prone to wear and failure.
Method used
The locking mechanism adopts a combination of a locking wheel and an inclined slide. The inclined slide reduces friction by guiding the piston rod. When the piston rod moves forward smoothly, the locking wheel slides outward and clamps inward when it moves backward. The friction can be adjusted by combining the positioning ratchet ring and the contact spring.
Benefits of technology
This achieves stable control of the liquid food delivery speed, reduces friction and wear, and improves the lifespan of the equipment and patient comfort.
