Device for inhalation therapy
View Patent ↗The invention relates to a device for inhalation therapy. Said device comprises an aerosol-producing device for spraying a liquid ( 3 ), preferably comprising a membrane ( 1 ), a support unit ( 6 ), an electromechanical transducer unit ( 7 ), and a connecting device ( 8,9 ) for supplying an oscillation control signal. The inventive device also comprises a control device ( 10 ) from which an oscillation control signal can be supplied to the connecting device of the aerosol-producing device, such that the aerosol-producing device sprays the liquid. Another control signal is supplied to the aerosol-producing device ( 1,6,7 ), moving the membrane ( 1 ) in oscillation in an audible frequency range, thus causing the emission of audible signals for a user.
1. Device for inhalation therapy, comprising:
a. an oscillatable membrane for nebulising a liquid,
b. an oscillation generating device having at least one connecting means,
c. a control means, from which a first oscillation control signal is supplied to the at least one connecting means of the oscillation generating device so that said oscillation generating device oscillates the membrane,
d. the at least one connecting means receiving the first oscillation control signal for oscillating said membrane when the first oscillation control signal is received such that a liquid disposed on one side of said membrane is nebulised through the membrane and is present on the other side of said membrane as an aerosol, and
wherein
said control means supplies a further control signal to the oscillation generating device during the first oscillation control signal, such that said oscillation generating device oscillates the membrane in an audible frequency range so as to emit an audible signal for a user.
2. Device for inhalation therapy according to claim 1 , wherein the further control signal is supplied to the oscillation generating device via the same connecting means as the first oscillation control signal.
3. Device for inhalation therapy according to claim 1 , wherein the oscillation generating device comprises an electromechanical transducer unit, in particular a piezoelectric element.
4. Device for inhalation therapy according to claim 2 , wherein the oscillation generating device comprises a support unit to which the electromechanical transducer unit and the membrane are attached.
5. Device for inhalation therapy according to claim 1 , wherein a generator unit is provided that generates the further control signal which is supplied to the oscillation generating device via the at least one connecting means.
6. Device for inhalation therapy according to claim 4 , wherein the generator unit is integrated in the control means.
7. Device for inhalation therapy claim 1 , wherein an energy supply means for the inhalation device is integrated in the control means.
