Also in analog connections, such as. and tele-plug connection, there may be, and often is, a voltageavailable that can be used to power it orthe energy-efficient components necessary in the measuring device1 for its function.
    In this way, the measuring device 1 can be designed completely without othersinternal or external energy sources. It is especially preferredget that the emergency device 1. lacks batteries. This brings oneextremely simple and reliable construction.
    An important aspect of the present invention is the existence ofthe cable 11, which allows the patient to see a screen 15 atcomputer devices. 14 simultaneously son1 the patient. blowing, and. hencefollow the variation of the blowing intensity over time. In this regardit is preferred that the cable 11 is at least 30 cm long.
    On the handheld computer unit. 14 there is a j softwarestored, which software is arranged to, when executedApplication text document 2012-06-08 120029EN101520253010on the computer unit, on a screen 15 on the handheld computer unit14 show the patient information about the patientexhalation capacity, for example in shape. of a continuousupdated graph 16 of exhalation intensity as a functionof time.

Depending on whether the cable ll is arranged to be connected to adigital or an analog input of the computer unit 14 is softwarearranged to read the signal from the correspondingentrance. Especially preferred is that the software isarranged. to read. an input of the computer unit 14 which isintended to receive and host a contact, for example by telephoneintended for the transmission of an analogue audio signal,plugqtyp,as described above. This means that the software isarranged to interpret an audio signal received during executionof the computer unit l4, not as an audio signal but as a signalwhich is information-bearing for the rotation of the rotating device20, the air flow through the blowing device 17 or the like,depending on the type of signal processing performed in thethe device 1 before the signal is delivered to the output l2.
