摘要： The present invention relates to a negative pressure wound therapy device, system and method. The negative pressure wound therapy device is connected with a dressing, and comprises a housing, a control circuit board, a pump, and an aspiration conduit. The pump generates negative pressure. The pump may comprise a voltage-actuated deformation element (such as piezoelectric vibration element) to push fluid from an aspiration end to a discharge end. The aspiration conduit has a pump end and a dressing end. The pump end is fluidly connected to the aspiration end of the pump, and the dressing end is fluidly connected to the dressing used for covering a wound. The control circuit board is disposed in the housing, controls the pump to generate the negative pressure in the aspiration conduit, and applies negative pressure to the wound covered by the dressing via the aspiration conduit.

摘要： An air pump is provided. An air pump includes an upper cover, a valve seat, a spacer, an air intake one-way valve and a piston assembly. The upper cover has an air outlet. The valve seat is disposed on a bottom of the upper cover. The spacer is disposed between the valve seat and the upper cover and has an air intake chamber and an air outtake chamber. The air intake chamber has an air intake passage communicated therewith, and the air outtake chamber having an air outtake passage communicated therewith. The spacer has a valve clack, so that air flows in a one-way direction from bottom to top. The air intake one-way valve is disposed and movable in the air intake passage so as to make the air flow in the one-way direction from top to bottom. The piston assembly is disposed under the valve seat.

摘要： A piezoelectric pump includes a piezoelectric element, a vibrating piece, a valve and a flow guiding member. The vibrating piece has a central zone attached to the piezoelectric element, a peripheral zone, a first recess, a stopper and a position limiting wall both protruding from the first recess, and a through groove disposed between the central zone and the peripheral zone and connected through the first recess. The valve is attached to the peripheral zone and has a non-straight through slit. The flow guiding member is attached to the valve and has a second recess and a channel both recessed in the flow guiding member, and a through hole. The channel is connected through the second recess and the through hole. A projection of the second recess projected on the plane which the valve exists covers the non-straight through slit. An operating method of a piezoelectric pump is further provided.

摘要： A pressure relief valve includes an outer frame, a ferromagnetic cylinder, a plastic air faucet, an electrical coil module and a spring. The plastic air faucet has a first end extending through a through hole of the outer frame and a second opposite end extending through a hollow channel of the ferromagnetic cylinder. The electrical coil module is located within the outer frame and has a central passage allowing the ferromagnetic cylinder to be accommodated inside. The ferromagnetic stopper is slidable along the central passage of the electrical coil module, wherein the ferromagnetic stopper has a seal gasket. The spring is located between the air faucet and the ferromagnetic stopper. When the electrical coil module is electrified, the ferromagnetic stopper and the ferromagnetic cylinder attract each other to against the resilient force of the spring to push the seal gasket against the air opening of the air faucet.
