It comprises a flexible sleeve (16) extending along a resonator (10), being held between two opposing surfaces (17, 18) thereof, one of these surfaces belonging to a solid (12) able to vibrate under the effect of a transducer (11) with a movement component (M), which subjects the sleeve (16) to repeated compressions of cross section, encouraging the fluid to flow. This yields a device that occupies very little space, is able to deliver clearly determined micro-flows, and is able to be leak-free when the excitation of the transducer (11) is interrupted. One possible application of the device is the delivery of medicinal products or other fluids to living organisms during surgical interventions or periodically, the device then being carried or borne by the living organism or implanted therein. |
