Abstract:
1. A portable medical suction device for discharging exudates of a wound portion on a negative pressure basis, the medical suction device comprising: a porous pad capable of being attached to the wound portion; a suction head that is positioned on top of the porous pad and thus collects and guides the exudates absorbed by the porous pad; drapes that seal the wound portion except for a connector of the suction head; a connection tube whose one end is connected to the connector of the suction head; 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; a main power switch that turns on the vacuum generator; a battery that supplies power to the vacuum pump and allows the medical suction device to be portable; and a vacuum pump controller that controls the power supply from the battery and extends a life of the battery while maintaining pressure applied to the vacuum pump within a range of pressure between a preset minimum pressure of 50 millimeter of mercury (mmHg) and a preset maximum pressure of 130 mmHg, wherein the vacuum pump controller causes the exudates of the wound portion to be continuously discharged through a drain tube while the main power switch is on by repeating: wherein the vacuum pump controller comprises:
