Microfluidic Surface Treatment Device

Abstract

The present invention relates to a microfluidic surface treatment device which delivers a precise quantity of at least one functional flowable compound. The device is provided with a reservoir, a microfluidic device comprising microchannels, and a pump able to pump the functional flowable compound through the microchannels. The pump is controlled by a microprocessor. The device can be a toothbrush, an electric toothbrush, a razor, an electric razor or a household cleaning device.

1 . Device comprising
 a head portion for contacting a surface,   a handle portion, and   at least one reservoir for containing a functional flowable compound, which is connected via a conduit to the head portion,   characterised in that   the conduit comprises at least one microfluidic device and at least one micro-pump, and the head portion comprises a plurality of hollow fibres protruding from the head portion to deliver the functional flowable compound, the plurality of hollow fibres being surrounded by toothbrush fibres for protection.   
     
     
         2 . A device according to  claim 1 , wherein the micro-pump is (or the micro-pumps are) controlled by a computer program. 
     
     
         3 . A device according to  claim 1 , wherein the device comprises at least one microprocessor. 
     
     
         4 . A device according to  claim 1 , wherein the device comprises at least one external interface. 
     
     
         5 . A device according to  1 , wherein the device is a handhold device. 
     
     
         6 . A device according to  claim 1 , wherein the device comprises an internal and/or external energy source. 
     
     
         7 . A device according to  claim 1 , wherein the device comprises at least one battery and/or at least one accumulator. 
     
     
         8 . A device according to  claim 1 , wherein the device comprises at least one removable (replaceable) part. 
     
     
         9 . A device according to  claim 8 , wherein the removable (replaceable) parts are batteries and/or accumulators, the containers for the functional flowable liquid, as well as the head portion (or parts of it). 
     
     
         10 . A device according to  claim 8 , wherein the removable (replaceable) is the head portion and/or parts of the head portion. 
     
     
         11 . A device according to any of the preceding  claim 1 , which is a toothbrush, an electric toothbrush, a razor, an electric razor or a household cleaning device.
