Abstract: Disclosed embodiments relate to apparatuses and methods for wound treatment with ultrasound. In certain embodiments, therapeutic ultrasound wound treatment apparatus includes a wound dressing configured to be positioned over a wound to provide a substantially fluid impermeable seal over the wound and a transducer to deliver therapeutic ultrasound to tissue. The therapeutic ultrasound wound treatment apparatus may further include a wound contact layer configured to be positioned in contact with the wound, a transmission layer positioned above the wound contact layer, an absorbent layer positioned above the transmission layer and configured to absorb wound fluid, and a backing layer positioned above the absorbent layer and including an orifice. Also disclosed are multiple parameters for the therapeutic ultrasound signal.

Abstract: A dispenser capable of dispensing a fluid via a vertically-oriented piezo device comprises a reservoir in the form of a replaceable cartridge containing a fluid to be dispensed, a planar piezo element having front and rear surfaces and which in use is oriented with its plane vertical and which is drivable to vibrate and thereby dispense fluid from the front surface, and a pump to draw a predetermined amount, or dose, of fluid from the reservoir and to drive the dose of fluid at a predetermined above-atmospheric pressure to the rear surface of the piezo element for dispensing.

Abstract: The invention relates to a device for optically monitoring a woven web of endless fabric on a mechanical weaving loom or a winding device. The monitoring device includes a holding element and extends over the entire width of the woven web of endless fabric. The monitoring device is directly in contact with the woven web of endless fabric and is held indirectly on the mechanical weaving loom, in the region between a delivering roller and the winding of the web of endless fabric onto a cloth beam or a large roller parallel to the delivery roller. The holding element has an axle located on the monitoring device and an axle located on the mechanical weaving loom, the two axles extending parallel to each other and being interconnected by a pivoting arm.
