An apparatus is described which supplies sterile, air-free physiologic saline as coolant at the tip of the handpiece. The device is activated by the foot control of the dental engine and the bur is flooded with saline the very moment the rotations begin. In the same way is stops instantaneously without afterdrip and without suckback. The components are either disposable or autoclavable. Metallic components are stainless steel.
描述了一种装置，该装置在机头尖端提供无菌、无空气的生理盐水作为冷却液。该装置由牙科发动机的脚踏控制激活，并且在旋转开始的那一刻，车针就被生理盐水淹没。同样，它能瞬间停止，无滴漏且无回吸。这些部件要么是一次性的，要么是可高压灭菌的。金属部件为不锈钢材质。
