DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an interactive respiratory regulator for relaxation purposes comprising: producing a corresponding respiratory signal, can be perceived by the user in order to influence his respiratory behaviour, respiratory signal received whether the respiratory pattern recorded during a predetermined time span meets a proadjustable standard for this parameter, and which at a certain error percentage sends a starting signal to the control device.
2. Description of Related Art
An apparatus of this kind, indicating to a user a desirable respiratory pattern, is known from the Netherlands patent specification 166.850, whereby this apparatus, in particular to combat the hyperventilation syndrome, is provided with a device for determining the cycle time. The corresponding frequency of the respiratory cycles is applied as parameter for the respiratory pattern. The recording device, being for instance a state in gauge or a mercury wire recorder applied to the chest of the user, produces a pulse signal with a repeat frequency corresponding with the respiratory frequency. This signal is fed to a time-determining device which compares this frequency with a preset standard or limit value. As soon as this processing device determines that the respiratory frequency is higher than the limit frequency it will set off a sound generator which during each respiratory cycle produces two, for the patient audible and differentiable tones.
However, not only patients suffering from hyperventilation, the symptom of which is an abnormally high respiratory frequency, exhibit a non-optimal respiratory behaviour, but also users who suffer, for instance, from respiratory sinus-arrhythmic deficiency, CNSLD or phobias or psychic traumas of any kind. Also users with a respiration which occurs mainly via the chest as opposed to abdominal respiration, have a form of non-optimal respiration, because in order for all organs to be well supplied with blood an effective abdominal respiration is important.
Describing the pattern of such a non-optimal respiration solely in forms of respiration frequency was shown not always to be adequate. The present invention ensues from the search for a useful, instructive feed back to the user with non-optimal respiratory patterns including others besides those which occur through hyperventilation. On these grounds it has been concluded that in order to analyze a respiratory pattern correctly, knowledge of especially the ratio between the in- and exhalation times is indispensable. The pause after exhalation is also an important parameter.
The known apparatus described above has, however, the limitation that it does not include that necessary extra information in the feed back process, thus offering insufficient possibilities for application to remedy disorders or to correct deficient respiratory patterns in general.
SUMMARY OF THE INVENTION
The object of the invention is to provide an apparatus in accordance with the kind mentioned in the preamble, which analyzes a user's recorded respiratory pattern in more detail and which not only tests a threshold with respect to the respiratory frequency.
To this end the interactive respiratory regulator according to the invention is characterized in that the processing device processes as parameter the ratio between the in- and exhalation time in a respiratory cycle, and optionally the pause after exhalation.
In a preferred embodiment the processing device includes the frequency of the respiratory cycles as a second parameter and the preadjustable standard also comprises a value for this parameter.
This apparatus can offer the user suffering from any kind of respiratory regularity disorders the advantage of useful feed back. Thus the apparatus offers a wide range of applicability not only with hyperventilation, but in principle with any non-optimal respiratory behaviour. The interactive respiratory regulator can, for instance also be used by people who, especially in no case of continual stress, wish to
