摘要：
Provided is a portable vacuum generator that can effectively save battery power of a vacuum pump for absorbing exudates from a suction head that is connected to a tube, and a medical suction device using the same. The medical suction device includes: a connection tube whose one end is connected to a connector of the suction head and a vacuum generator including a vacuum pump that is connected to the other end of the connection tube and having a motor for generating negative pressure, and a vacuum pump controller that controls a power supply for the vacuum pump so as to maintain a vacuum state, in which the vacuum pump controller blocks the power supply for the vacuum pump until pressure of the vacuum pump falls down to preset minimum pressure in the case that the current pressure that is applied to the vacuum pump reaches preset maximum pressure, and drives the vacuum pump until pressure of the vacuum pump reaches the preset maximum pressure in the case that the current pressure falls down to the preset minimum pressure.
