げられるという課題があった。However, in the above-mentioned conventional configuration, when the sleeping person is a bedridden elderly person, it is often impossible to operate the air blowing operation by himself, and a nurse is required. At that time, the nurse must perform a blowing operation for the sleeping person, and in this case, there is a problem that the operation is complicated and the operation may be forgotten. For this reason, a method of performing automatic operation using a timer is conceivable, but in order to prevent bedsores, it is desirable to perform a blowing operation by knowing a sleeping state such as whether or not a sleeping person is turning over. However, with the conventional method using a timer, it is not possible to know the sleeping state, and if it is desired to do so, some kind of detector must be attached to the body of the sleeping person. In this case, there is a problem that sleep is hindered by wearing the detector.

It is.

And control means for controlling the blower in accordance with the continuation time.

止する。According to the present invention, the sleeping state is known by the body movement detecting means detecting the body movement of the sleeping person. That is, when the sleeping person is performing rough movement such as turning over, the blower is stopped because bed slippage is unlikely to occur. However, if the sleeping person continues to be in a limb-moving state with only heartbeat and breathing (so-called turning over, etc.)
The duration of the state is measured by a timer, and when a predetermined time is reached, the blower is operated via the control means to prevent bedsore.

するのである。In the above configuration, when a human body is present on the mat 5, the body motion detecting means 17 is deformed by the body motion of the human body on the mat 5, such as heartbeat, breathing, and turning over, and the voltage due to the piezoelectric effect is reduced. Occur. Then, only a predetermined frequency component of the generated voltage output passes through the low-pass filter 20, is amplified and rectified, and is then integrated by the integrator 23. FIG. 4 shows an output signal of the integrator 23 in an actual situation. As shown in the figure, there is a large output when rough body movement such as entering the bed, leaving the bed, turning over, etc. An output is obtained, and the output becomes zero when the user is out of bed. That is, as long as the human body is present on the mat 5 at bedtime, at least a low-level output can be obtained by the above-mentioned minute movement of the human body accompanying heartbeat and respiration. Utilizing this fact, the comparator 24 determines that the subject is in the fine body movement state if the output signal of the integrator 23 is within the range of Va and Vb shown in FIG. Then, the duration of the fine body movement is measured by the timer 25, and when the duration reaches a certain time,
The blower 13 is operated via the control means 26 to prevent bedsore.
