An embodiment of the body motion detection bed according to the present invention will be described below.
Fig. 1 is an overall view of a body motion detection bed according to an embodiment of the present invention, fig. 1(a) is a perspective view of the body motion detection bed, fig. 1(b) is a side view of the body motion detection bed, and fig. 1(c) is a plan view of the body motion detection bed.
As shown in fig. 1, the body motion detecting bed of the present embodiment includes: four legs 11, four rods 12 connecting the legs 11 to each other, and a sheet 13 disposed at least between a pair of the rods 12 facing each other. The rod 12 includes a pair of short rods 12a and 12b opposed to each other and a pair of long rods 12c and 12d opposed to each other.
The body motion detection bed of the present embodiment has: a sensor pad 20 (see fig. 2) which incorporates a sensor 21 for detecting body movement, a sensor controller 30 which receives a detection signal from the sensor pad 20 and outputs information based on the received detection signal, and a controller holder 40 which holds the sensor controller 30.
The controller holder 40 is mounted to the rod 12.
Fig. 2 is a configuration diagram showing a sheet and a sensor mat of the body movement detection bed, fig. 2(a) is a developed plan view of the sheet of the body movement detection bed, fig. 2(b) is a perspective view of the sensor mat of the body movement detection bed, and fig. 2(c) is a configuration diagram showing the inside of the sensor mat.
The sheet 13 has, on its outer periphery: a short ear portion 13a attached to the short bar 12a (see fig. 1), a short ear portion 13b attached to the short bar 12b (see fig. 1), a long ear portion 13c attached to the long bar 12c (see fig. 1), and a long ear portion 13d attached to the long bar 12d (see fig. 1).
the short lug 13a is formed with a notch 13e for exposing a part of the short bar 12a when attached to the short bar 12 a. The controller holder 40 is attached to the short rod 12a exposed through the cutout portion 13 e.
A sensor pad pocket 13f is provided on the back surface of the sheet 13. The sensor pad pocket 13f is provided with: one side of the short ear portion 13a is open, and the other three sides are closed.
The sensor pad 20 is housed in the sensor pad pocket 13 f. By housing the sensor pad 20 in the sensor pad pocket 13f, the sensor pad 20 can be easily attached and detached.
The bed sheet 13 and the sensor pad pocket 13f use, for example, polyester fibers.
inside the sensor pad 20 shown in fig. 2(b) and 2(c), two piezoelectric sensors are provided as sensors 21 for detecting body motion. By using a piezoelectric sensor, the body dynamics conducted to the sheet 13 can be correctly detected. However, by providing a plurality of sensors 21, not only the number of times of the body movement but also the size of the body movement can be detected with high accuracy.
since the sensor pad 20 is disposed on the back surface of the bed sheet 13 in this manner, the influence of contamination with feces and urine is small, the sensor pad 20 can be attached and detached even in a state of being laid on the bed, and body motion detection can be performed by a simple and easily stored bed.
Fig. 3 is a configuration diagram showing a controller holder of the body motion detecting bed, fig. 3(a) is a perspective view of the controller holder, fig. 3(b) is a perspective view showing a state in which a sensor controller is held by the controller holder, and fig. 3(c) is a configuration diagram showing an operation of the controller holder.
The controller holder 40 includes a holding portion 41 that holds the sensor controller 30 and an arm portion 42 attached to the bar 12. The holding portion 41 has rising walls at least on both side surfaces and on the rear surface, and holds the sensor controller 30 in a space surrounded by these rising walls. One end of the arm 42 is connected to the bottom surface of the holding portion 41, and a ring 42a is formed at the other end of the arm 42. The controller holder 40 is attached to the rod 12 via the ring portion 42 a.
By holding the sensor controller 30 by the controller holder 40, it is possible to prevent the sensor controller 30 from being damaged or mishandled when the sensor controller 30 is placed on the bed surface or the bed sheet 13, and to accurately grasp information output from the sensor controller 30.
Further, the sensor controller 30 includes: a no-body-movement alarm unit (not shown) that outputs a no-body-movement alarm when no body movement is detected for a predetermined period, and an alarm stop unit (not shown) that deactivates the no-body-movement alarm unit, wherein the sensor controller 30 can detect a no-body-movement state and can stop the output of the no-body-movement alarm in a no-lying person state.
the controller holder 40 is able to rotate relative to the rod 12.
As shown in fig. 3c, the controller holder 40A can be positioned above the bar 12 during the body motion detection operation (when lying on the bed), and the controller holder 40B can be disposed on the back surface side of the bed sheet 13 during storage of the body motion bed.
Since the sensor controller 30 can be disposed on the back surface side of the bed sheet 13 by rotating the controller holder 40 in this manner, the body motion detecting bed can be easily stored in a state where the sensor controller 30 is attached.
Fig. 4 is an overall view showing a storage state of the body motion detecting bed, fig. 4(a) is a perspective view showing the storage state of the body motion detecting bed, and fig. 4(b) is a side view showing the storage state of the body motion detecting bed.
