ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a respiration monitoring system, and more particularly to a respiration monitoring system capable of monitoring the state of disorder of the patient's respiratory system during sleep.
BACKGROUND OF THE INVENTION
A conventional medical system for diagnosing a respiratory disease of a sleep apnea syndrome is shown in FIG.
7
. Here, this system
100
has an air flow sensor
101
, a chest/abdominal movement sensor
102
, a snore sensor
103
, a body attitude sensor
104
, a blood oxygen saturation sensor
105
, and a data recorder
106
. These sensors
101
-
105
are put on the patient's body during sleep. The data produced by the sensors is recorded by the data recorder
106
.
The recorded data is sent by off-line transfer from the data recorder
106
to an external data analyzer
107
, by which the data is analyzed for the diagnosis of respiratory disease. In the diagnostic procedure, the distribution of blood oxygen saturation is first examined, and if a disease is suspected, the patient undergoes more precise inspections based on the data provided by the remaining sensors.
However, for diagnosis as shown in
FIG. 7
, it is necessary to put many sensors
101
-
105
on the patient's body during sleep. Therefore, it is not only awkward for the patient to wear these sensors
101
-
105
with lead wires during sleep, but the sensors must be removed and the patient must be turned over. The present invention was developed in light of these drawbacks.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a respiration monitoring system which is capable of monitoring the state of disorder of the patient's respiratory system during sleep based on detecting body movement caused by respiration, and without requiring the sensors to be placed directly on the patient's body.
It is a further object of the present invention is to provide a respiration monitoring system that is easily used at home for monitoring the patient's respiratory system, and is useful for the primary care of sleep apnea syndrome.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are intended for purposes of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
