DETAILED DESCRIPTION OF THE INVENTION

The following description is provided, so as to enable any person skilled in the art to make use of said invention and sets forth the best modes contemplated by the inventor of carrying out this invention. Various modifications, however, are adapted to remain apparent to those skilled in the art, since the generic principles of the present invention have been defined specifically to provide an inhaler for preventing and treating respiratory diseases and a method of doing the same.

Reference is now made to FIG. 1 presenting a schematic diagram of inhaler 100 having housing 150 accommodating all its components. Specifically, an air flow from blower 20 is conducted by passage 10 which is in fluid communication with mouthpiece 50. A flow rate of the airflow is controlled by motorized gate valve 120 driven by actuator 110. Passage 10 is provided with humidifier branch inlet 80 allowing fluid communication between a humidifier (nor shown) connectable to humidifier branch inlet 80. Second passage 40 is provided with nozzle 30. In addition, second passage 40 is in fluid communication with nebulizer branch inlet 90 configured for connecting the humidifier thereto. Electric motor 70 drives rotating disc 60 having a cutout (not shown) such that first and second passages 10 and 40, respectively, are arranged such that rotating disc 60 blocks and releases first and second passages 10 and 40 in an alternate manner. It should be noticed that an excess pressure created by blower 20 when the cutout (not shown) on rotating disc 60 coincides with first passage 10 is vented to surrounding atmosphere when the cutout coincides with second passage 40. The exhaled air accommodated only in mouthpiece 50 is potentially pressurized back into the patient's airway. In other words, the dead-space effect is minimized.

Control unit 160 is configured for controlling electric motor 60, passage gate valve 120, humidifier gate valve 140 and air pressure source gate valve 270. Control unit 160 is preprogrammed for implementing a predetermined treatment protocol. Pressure sensor 65 provides a feedback to control unit 160 during implementing the predetermined treatment protocol.

Reference is now made to FIG. 2 presenting arrangement 200 for connecting a nebulizer 220 to the inhaler 100 (not shown). The aforesaid nebulizer is connected to nebulizer branch inlet 40 having a cylinder reciprocatively displaceable within nebulizer branch inlet 40 between closed position 210 at an exhalation phase and open position 210a at an inhalation phase. In open position 210a, nebulizer 220 is fluidly connected with mouthpiece 50. Pipes 240 and 250 are connectable to an oxygen source and a pressurized air, respectively. An oxygen flow rate is controlled by tap 230. Gate valve 270 driven by actuator 260 is closable at inhalation phase and openable at exhalation phase. Numeral 245 refers to an oxygen sensor detecting an oxygen gas flow via pipe 240.

Reference is now made to FIGS. 3a to 3d illustrating operation of gate valves. As shown in FIG. 3a, the aforesaid gate valves are shown as shutters 120, 140 and 270.

Contrary to this, acoustic sensor 190 can be placed on a patient's chest. The acoustic pattern obtained by sensors 201 and/or 190 can be used for adaptation of a therapeutic protocol to a specific patient's condition. Numeral 204 refers to a sensor which detects gas composition of air exhaled by the patient.

Presence of nebulizer 220 is reported by nebulizer present sensor 207. Presence of humidifier is reported by humidifier presence sensor 212. Humidity of the air flow in humidifier branch inlet is detected by humidity sensor 208.
