Abstract
A portable electric motor driven ear cleaning device consisting of a rotary brush having soft hairs, a body, having a brush holder, which is capable of receiving and engaging the rotary brush and wherein the body is of three portions, a shoulder portion, a central body and an end and wherein the shoulder portion is tapered so that when the brush is inserted in the ear canal, the shoulder portion prevents ear drum penetration by said brush.
Claims18
A portable ear cleaning device comprising:
- a brush comprising:
- a brush element comprising a plurality of soft hairs which are limp when not rotating and which extend radially outward due to centrifugal force when rotating, and
- a non-bending rod;
- wherein the brush element has an overall length which is substantially equivalent to the length of the ear canal to be cleaned;
- and is between 1 and 20 mm in length
- a body comprising:
- a brush holder capable of receiving and engaging said rod at one end;
- and
- further wherein said body comprises:
- an tapered shoulder portion,
- a central body, and
- an end, and
- further wherein said shoulder portion is tapered so that when the brush element is inserted in an ear canal, the shoulder portion prevents eardrum penetration by said brush element;
- a motor disposed within said body having a rotatable extension protruding there from which can engage at one end, said brush holder;
- a switch with actuation means disposed within said body connected to said motor for turning on and off said motor;
- and
- a transformer for converting current from AC to DC current to engage said motor and rotate said brush.
