Abstract

An apparatus for producing pressure pulses intended for application to the external acoustic meatus of a patient, for the purpose of influencing the hydrodynamic system of the inner ear in the treatment of certain diseases, particularly Menieres disease, comprises two rotary air-pumps (1, 2) of variable, controllable speed. Respective pressure sides of the two pumps (1, 2) can be selectively connected to and disconnected from a common pressure-pulse output line (7), by means of a respective controllable valve (5, 6). The pumps are driven by electric motors (3, 4) and the rotational speed of the motors and the settings of the electrically operable valves (5, 6) are controlled by a control unit (9) incorporating a microprocessor, in response to a program relating to a desired shape, frequency, amplitude, duration etc. of the generated pressure pulses, this program being stored in the control unit. The apparatus also includes a pressure transducer (8) which is connected to the output line (7) and which produces a signal representing the momentary pressure prevailing in the output line (7), this signal being applied to the control unit and used therein to control the two pumps (1, 2) and the two valves (5, 6).

Claims

1. An apparatus for generating pneumatic pressure pulses for application to the external acoustic meatus of a patient for the purpose of influencing the hydrodynamic system of the inner ear, comprising:

two rotary air-pumps (1,2) of variable controllable speed;

two controllable valves (5,6) downstream of said two rotary air-pumps, one said valve receiving the output of one of said rotary air-pumps and another of said valves receiving the output of another of said air-pumps;

an output line (7) from said valves and a meatus mating means (11) for pressure-tight connecting with the external acoustic meatus of the ear of the patient along said output line; and

control means (9) for controlling the speed of the two air-pumps (1,2) and the settings of the two valves (5,6) to produce a pulsed output of air to the output line (7), the meatus mating means (11) and the external acoustic meatus of the ear of the patient according to a preselected program controlling the shape, frequency and amplitude of the pressure pulses produced in the output line (7).

2. An apparatus according to claim 1 further comprising pneumatic means (12) to control said pressure-tight connection.

3. An apparatus according to claim 1, characterized in that the control unit is provided with, or is connectable to means for reading said program into the control unit.

4. An apparatus according to claim 1, characterized in that the control unit (9) is provided with, or is connectable to means for the visual presentation and/or write-out of data relating to the program stored in the control unit.

5. An apparatus according to claim 1, characterized in that said valves (5,6) are arranged to place the output line (7) in communication with the ambient atmosphere when breaking said connection between said output line (7) and the pressure side of the associated pump means (1,2).

6. An apparatus according to claim 5 characterized in that the control unit is provided with, or is connectable to means for reading said program into the control unit.

7. An apparatus according to claim 1, characterized by a pressure transducer (8) which is connected to said output line (7) and which is adapted to produce a signal representing the momentary pressure prevailing in the output line, this signal being applied to the control unit (9).

8. An apparatus according to claim 7 characterized in that the control unit is provided with, or is connectable to means for reading said program into the control unit.

9. An apparatus according to claim 7 characterized in that said valves (5,6) are arranged to place the output line (7) in communication with the ambient atmosphere when breaking said connection between said output line (7) and the pressure side of the associated pump means (1,2).

10. An apparatus according to claim 9 characterized in that the control unit is provided with, or is connectable to means for reading said program into the control unit.
