Detachable pump and the negative pressure wound therapy system using the same

The present invention relates to a detachable pump and a negative pressure wound therapy (NPWT) system using the same. The detachable pump comprises: a top module, including a motor set and a top elastic member; and a bottom module, arranged beneath the top module in a manner that it is connected to the top module by a detachable connection mechanism and comprised of: a base configured with an inlet and an outlet; at least an one-way suction valve; at least an one-way drain valve; a diaphragm element; and a bottom elastic member. With the aforesaid system, spent liquid can be prevented from flowing back to a wound section or the base by the cooperation of the suction valve and the drain valve as the top elastic member is configured to be pushed by the motor set for enabling the resulting resilience of the top elastic member to counter with the resilience of the bottom elastic member in a manner that the diaphragm element is propelled for enabling the detachable pump to generate a vacuuming force. By incorporating the aforesaid detachable pump into a NPWT system along with dressings and absorbent materials, spent liquid of a wound is drawn by the pump to be absorbed directly by the absorbent materials by way of the dressings so that not only the piping length and the volume of the NPWT system are reduced, but also the power requirement of the pump is decreased.
