The RC-Cornet-N® is a therapeutic aid to clear your sinuses. The pressure and flow fluctuations created by the device 'massage' the sinuses and widen the narrow passages so that air can pass into the sinuses. At the same time, mucous that blocks the passages is mobilised and drained. The RC-Cornet-N® thus enhances the natural healing mechanisms of the body. It helps to drain mucous from the sinuses and therefore relieves the feeling of being 'bunged up'.
To protect the sinuses, the human body constantly produces small quantites of mucous which acts as a lining to the airways. Usually little hairs (cilia) that are in constant motion transport the mucous over narrowings and orifices (Fig.2) into the nose. From here the mucous is subconciously swallowed.
When the body is weakend by external influences (infections, allergic reactions etc.), narrowings in the sinus passages occur. Often there is also an increased production of more viscous mucous that leads to blockage of these passages. Therefore the natural drainage and ventilation system of the sinuses fails (Fig.3).
As a result, pressure can build up in the sinuses and the oxygen supply to the sinuses is disrupted leading to inflammation of the whole area.
A good example of these effects is the closure of the eustachian tube. The eustachian tube connects the nasal sinuses with the ear in order to balance pressure differences on the ear. Blockage of the eustachinan tube leads to hearing impairment, inflammation of the ear as well as severe pain. These dysfunctions are especially pronounced when the immune system is weakened and the body is exposed to large pressure fluctuations as encountered while diving or in an aircraft.
A well known remedy is the application of a positive pressure to the sinuses (holding your nose and mouth closed and blowing hard) which often opens the eustachian tube for a short period and restores the pressure balance (Fig.4). The RC-Cornet-N® helps to open up the blockages and drain mucous so that passages are permanently unblocked. This leads to a more comfortable and sustained recovery.
