PORTABLE VACUUM GENERATION DEVICE, AND MEDICAL SUCTION DEVICE USING SAME

摘要

The present invention relates to a portable vacuum generation device which can effectively save the power of a battery of a vacuum pump for sucking exudate from a suction head connected to a tube, and a medical suction device using the same. The present invention comprises: a connecting tube of which one end is connected to a connecting pipe of a suction head; and a vacuum generation device connected to the other end of the connecting tube, comprising a vacuum pump for generating negative pressure, having a built-in motor, and a vacuum pump controller for controlling the supply of power to the vacuum pump so as to maintain vacuum state. The vacuum pump controller blocks the supply of power to the vacuum pump until the pressure of the vacuum pump falls to the predetermined minimum pressure if the present pressure applied to the vacuum pump reaches the predetermined maximum pressure, and operates the vacuum pump until the pressure of the vacuum pump reaches the maximum pressure if the present pressure falls to the minimum pressure.
