Embodiment Construction

[0039] figure 1 An ultrasound-assisted wound cleaner 1 in the form of a hand-held appliance according to the invention is shown. The wound cleaner comprises a base 2 and a replaceable cleaning attachment 3 . The base 2 comprises an energy accumulator 12 and an inductive transducer 11 for charging the energy accumulator 12 . The base 2 also includes an ultrasonic generator 13, ie a generator for generating high-frequency currents. The frequency of the high-frequency current can be adjusted between 20 kHz and 2 MHz by controlling the switch 18 .

[0040] The adjustment frequency is displayed on the optical display element 19 . The high-frequency current generated by the sonotrode 13 is transmitted to the acoustic transducer 24 via the contact points 17a, 29a in the base 2 and the cleaning attachment 3 and via electrical leads 28a. The acoustic transducer 24 is arranged in the front region of the cleaning attachment 3 , namely the bristle head 31 . The acoustic transducer 24...

Abstract

The invention relates to an ultrasound-assisted wound cleanser in the form of a handheld device, comprising an integrated vibration motor, an integrated ultrasound generator, an integrated energy source for the vibration motor and the ultrasound generator, and a replaceable cleaning attachment which can be driven by the vibration motor for abrasively removing wound coatings. The cleaning attachment has an acoustic transducer which is designed to convert the electric oscillations generated by the ultrasound generator into sound waves, a device for reinforcing and / or distributing and / or transferring the ultrasound waves, and brushes and / or lamellas for the abrasive removal. The invention further relates to a method for cleaning wounds, wherein a cleaning attachment with brushes for abrasively removing wound coatings is moved by a vibration motor. The cleaning attachment is oscillated by an ultrasound generator, and the oscillations for supporting the removal of wound coatings are transmitted into the wound via a transmission medium.

Description

technical field [0001] The present invention relates to an ultrasonically assisted wound cleaner in the form of a hand-held appliance and a method of cleaning a wound. Background technique [0002] Various methods and devices for cleaning wounds are known from the prior art. [0003] For example, US 2005 / 0278877 A1 discloses a brush for cleaning chronic wounds. The brush has a rotary drive for rotational movement of the brush. [0004] Ultrasonic assisted wound cleaners are also known from the prior art. [0005] For example by or a known kind of system produced by Misonix Inc. has a stationary unit and a hand-held part connected by a hose. The stationary unit houses pumps for delivering irrigation and coupling fluids and an ultrasonic generator. The hand-held part connected to it by a hose comprises a cleaning attachment made of metal and placed in ultrasonic vibrations and an opening through which liquid delivered from the fixed base can enter said wound. [0006] A...
