Abstract
The utility model discloses a liquid blocking device for an infusion pump. The liquid blocking device comprises a liquid stopping clamp, a first elastic element and a self-locking mechanism. The liquid blocking clamp is provided with a first revolving shaft. The first elastic element acts on the liquid blocking clamp with preacting force, and the self-locking mechanism drives the liquid blocking clamp to rotate around the first revolving shaft and positions the liquid blocking clamp. The self-locking mechanism is provided with a power input end and a power output end. The power output end is in contact with the first face of the liquid blocking clamp in an abutted mode. One end of the first elastic element is connected to the liquid blocking clamp, and the first elastic element and the self-locking mechanism drive the liquid blocking clamp to rotate around the first revolving shaft in opposite directions respectively. The power output end of the self-locking mechanism drives the liquid blocking clamp to rotate. When the liquid blocking clamp rotates to a certain angle, the self-locking mechanism positions the liquid blocking clamp, a rubber pipe used in infusion is then placed in the seam between the liquid blocking clamp and the self-locking mechanism, and the self-locking mechanism is unlocked. The liquid blocking clamp is matched with the supporting plane of the rubber pipe under the pressure of the first elastic element, and therefore blocking liquid is achieved. The liquid blocking device is simple in structure and convenient to operate.
