Abstract: An ultrasonically driven pump, which may be used for sampling body fluids or atomizing liquids, has a stationary outer needle and an inner needle mounted within the bore of the outer needle. The distal end of the inner needle is positioned adjacent to the distal end of the outer needle. The inner needle is ultrasonically vibrated by an ultrasonic actuator without vibrating the outer needle, with resulting draw of liquid through the distal end of the outer needle into the bore of the inner needle for discharge through the proximal end of the inner needle. The outer needle can be formed to have a penetrating tip suited for penetrating the skin of a subject to allow sampling of body fluids including interstitial fluids. The pump can also be used for atomizing liquid, by drawing liquid from a supply that is pumped from the distal end to an open proximal end of the inner needle where the liquid is discharged by atomization into the atmosphere.

Abstract translation: 可用于取样体液或雾化液体的超声波泵具有固定的外针和安装在外针的孔内的内针。 内针的远端定位成与外针的远端相邻。 内针被超声波致动器超声波振动，而不会使外针振动，从而将液体从外针的远端抽出到内针的孔中，以通过内针的近端排出。 外针可以形成为具有适于穿透受试者皮肤的穿透尖端，以允许对体液（包括间质液）进行取样。 该泵还可用于雾化液体，其是从从远端泵送到内针的开口近端的液体从液体通过雾化排放到大气中排出液体。
