System, method, use and information storage medium for practicing of an inhalation process
An inhalation training system and a method for practicing of an inhalation process and a method of operating a portable communications device in this respect and to an information storage medium are improved. An air flow during inhalation is converted into an acoustic signal, especially a whistling tone. The acoustic signal is picked up by a microphone of a portable communications device, such as a smartphone, and is electronically evaluated. The inhalation training system has a mouthpiece and a converter apparatus for converting the air flow into the acoustic signal and in addition has a holding apparatus for especially detachable holding of the communications device.
1. An inhalation training system for practicing of an inhalation process of a patient without a capability for dispensing of an inhalant, comprising:
a body portion without a means for receiving a through-flow of air or inhalant,
a mouthpiece for enabling an air flow to be produced upon inhalation by a patient thereat, said mouthpiece being connected to an end of the body portion,
a converter apparatus that has a whistle, the whistle being located at the mouthpiece in a manner able to produce an audible whistling from the air flow, and
a portable communications device that is adapted to receive the whistling by means of a microphone and which is detachably located within said body portion,
wherein the portable communications device is one of a mobile phone and a tablet computer,
wherein the body portion comprises a holding apparatus having an interior space sized for receiving and holding the portable communications device in a position for measuring the signal produced by the converter apparatus, and
wherein the holding apparatus is constructed for detachable holding of the portable communications device.
2. The inhalation training system as claimed in claim 1 , wherein the holding apparatus is adapted to at least partially encompass the portable communications device on opposite sides thereof.
3. The inhalation training system as claimed in claim 1 , wherein the converter apparatus is adapted to produce a characteristic acoustic signal indicative of a type of the mouthpiece and to enable detection and evaluation thereof.
4. The inhalation training system as claimed in claim 1 , wherein the holding apparatus comprises two holding regions, which are movable relative to one another in order to open the interior space to enable insertion and removal of the portable communications device into and from the body portion.
5. The inhalation training system as claimed in claim 1 , wherein the portable communications device is mechanically connected to the converter apparatus, when the portable communications device is held by the holding apparatus.
