摘要：
A device and method for dispensing a liquid and a gas from a tip includes a support structure, a control unit, and a drive unit. The liquid is held within a container. The support structure is adapted to hold the container. The control unit directs the drive unit to expel liquid from the container according to a predetermined rate. The control unit further directs the drive unit according to first, second, and third modes of operation. During the first mode, neither gas nor liquid is dispensed from the device. During the second mode, only gas is dispensed from the device. During the third mode, both gas and liquid are dispensed from the device. Furthermore, the control unit is only selectable and operable by a user through the first, second, and third modes in a sequential manner.
