Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a mattress device that makes it possible to remotely determine whether or not a patient is on the mattress of a bed.

(Prior Art) In a hospital, if a patient who must be lying on a bed rest slips out of the hospital room or falls from the bed rest, the patient must be informed as soon as possible. It may be life-threatening.

Conventionally, in order to find out whether a patient is lying on a mattress, for example, a nurse visits each hospital room at predetermined intervals.

However, if the patient's room is to be visited every predetermined time, there is a risk that it will not be possible to detect at an early stage if a patient has disappeared from the patient's room or has fallen from a pine tree. In such cases, it may take a lot of effort.

(Problem that the invention aims to solve) In the past, in order to find out whether or not a patient was on a pine tress, a nurse had to make rounds at predetermined intervals, which resulted in delays in discovery and There were some things that took time and effort.

This invention was developed based on the above circumstances, and its purpose is to be able to remotely know whether a patient is on a pine tress, and to prevent the patient from leaving the hospital room or on the pine tress. To provide a pine stress device capable of early detecting a fall from a tree.

[Structure of the idea]

(Means and effects for solving the problem) In order to solve the above problem, this invention uses a spring unit formed by connecting a large number of springs in a matrix, and a spring unit that is bonded and mounted on the upper surface of this spring unit. a first hard or semi-hard layer, a soft cushion layer provided on the upper surface of the first hard or semi-hard layer, and a soft cushion layer provided with perforations at predetermined intervals along the longitudinal direction of the spring unit. a plurality of through holes provided therein, a plurality of switches each housed in each through hole and turned on by applying pressure; a first display section which displays the fact when the switches are turned on; a second display section that indicates this when turned off; a second hard or semi-hard layer bonded to the upper surface of the cushion layer; and a second hard or semi-hard layer covering the second hard or semi-hard layer. It is equipped with an exterior body. The first display section and the second display section make it possible to know whether or not there is a patient on the mattress.

(Example) An example of this invention will be described below with reference to the drawings. Figure 3 shows bed 1, and this bed 1
has frame 2. This frame 2 is provided with a headboard 4 at one end of a mounting section 3 and a footboard 5 at the other end, and a mattress 6 is mounted on the mounting section 3. This mattress 6 has a spring unit 9 in which a large number of coil springs 7 are connected in a flat plate shape by helical wires 8. A sheet-like first mesh member 11 as a hard or semi-hard layer is laid on the upper surface of the spring unit 9, and a first mesh member 11 made of urethane foam or the like as a soft layer is laid on the first mesh member 11. A cushion material 12 is attached. A press arm 13 is placed on the first cushion material 12 via a second mesh member 10 similar to the first mesh member 11.
A second cushion material 15 formed by sequentially bonding a urethane foam 14 and a urethane foam 14 is laminated, and this second cushion material 15 is covered with an upper exterior body 16.

A plurality of through holes 17 (four in this embodiment) are bored in the first cushion material 12 along its width direction at predetermined intervals in the longitudinal direction.
Fourth switches 18a to 18d are accommodated, respectively, and fixed with clips 20. These switches 18a to 18d are provided on a hollow belt-shaped body 19 made of a soft material such as rubber or synthetic resin and having approximately the same thickness as the first cushion material 12, and on the inner surface of the upper wall of this belt-shaped body 19. The first conductor 21 is provided on the lower wall of the band-shaped body 19, and the second conductor 22 is provided on the lower wall of the strip-shaped body 19, facing away from the first conductor 21. Therefore, when the first cushion material 12 is compressed by the load applied by the patient lying on the upper exterior body 16,
The strip body 19 of the switches 18a to 18d is the second
The first conductor 2 provided on the band-like body 19 is compressed and deformed by being pressed by the net-like body 10 of
1 and the second conductor 22 are electrically connected. In other words, the switches 18a to 18d are turned on.

A cushion material 23 such as urethane foam is bonded to the lower surface of the spring unit 9, and the cushion material 23 is covered with a lower exterior body 24.

As shown in FIG. 1, the first to fourth switches 18a to 18d have a first lead wire 25 connected to the first conductor 21, and a first lead wire 25 connected to the second conductor 21.
2 is connected to a second lead wire 26, and this second lead wire 26 is grounded. The first lead wire 25 is connected to a DC power supply 27 via a resistor 27a, and is also connected to a negative input terminal of a first inverting amplifier 28 constituting a NOR circuit. This first inverting amplifier 28
The output terminal of is connected to the negative terminal of the second inverting amplifier 29 and a blue LED 32 as a first display section via a resistor 31, respectively. A resistor 33a is connected to the output terminal of this second inverting amplifier 29.
via a red LED 33 as a second display section,
alarm lamp 3 via the first manual switch 34a.
5 is connected. This alarm lamp 35 has second, third manual switches 34b, 34c,...
are connected to each other. Each manual switch 34
b, 34c... are respectively blue as mentioned above.
The first to fourth switches 18a to 18d of the pinerests in each hospital room are connected via the LED 32 and red LED 33.
It is connected to the.

The blue LED 32, red LED 33, manual switches 34a, 34b, 34c, and alarm lamp 35 are provided in the central control room.

According to such a configuration, the patient can avoid pine stress 6.
When lying down, the weight of the patient compresses the first and second cushioning materials 12, 15. When the first cushion material 12 is compressed, the first mesh member 11 bonded to its upper surface is displaced downward, so that the first mesh member 11 controls the first to fourth switches 18a to 18d. The strip 10 is compressed. Then, the first conductor 21 and the second conductor 22 provided on the strip 19 come into electrical contact, thereby reducing the DC voltage previously applied to the first inverting amplifier 28. is grounded through each of the switches 18a to 18d and the second lead wire 26. As a result, the H signal applied to the negative terminal of the first inverting amplifier 28 is removed, and the H signal is output from the output terminal of the first inverting amplifier 28.
A signal will be output, which will cause the blue LED 32 to light up, indicating that the patient is on the mattress 6. Furthermore, since the output signal from the first inverting amplifier 28 is also input to the second inverting amplifier 29, the output signal from the second inverting amplifier 29 becomes L, so the red LED
33 does not light up. Therefore, it can be confirmed that a patient is on the pinerest 6 in the intensive care room.

Furthermore, if the patient falls off the mattress 6 or slips out of the hospital room, no load is applied to the mattress 6, so the first to fourth switches 18a to 18d are turned off. Then, since the voltage of the DC power supply 27 is not grounded and is applied as an H signal to the first inverting amplifier 28, the output signal from this inverting amplifier 28 becomes L. As a result, blue
Since the LED 32 is not lit and the second inverting amplifier 29 outputs an H signal, the red LED 33 is lit. Therefore, red LED3
3 is lit, the patient is placed in the pine tress 6.
You can know that you are not above. Further, in this case, if the first manual switch 34 is turned on, the alarm lamp 35 lights up, so that the user can also know that the patient has disappeared from the mattress 6.

That is, by turning on the first, second, third, ... manual switches 34a, 34b, 34c, ..., the alarm lamp 35 will be activated even if a patient disappears from any of the mattresses 6 in each hospital room. Then you can know that. Therefore, only the alarm lamp 35 is monitored, and this alarm lamp 35
If it lights up, all you have to do is check which hospital room's red LED 33 is lit, which makes monitoring easier when there are many hospital rooms.

In addition, the first to fourth switches 18a to 18d
The through hole 17 formed in the first cushion body 12
A first net-like body 11 and a second net-like body 10 are placed on the upper and lower surfaces of the first cushion body 12, respectively.
were joined. Therefore, even if a load is partially applied to the upper surface of the pinerest 6, the load is distributed over the entire surface of the pinerest 6 by the second net-like body 10, and moreover, the load is transferred to the first net-like body 11. You can be sure of receiving it. Therefore, since the first cushion body 12 is compressed as a whole, the first cushion body 12 is compressed as a whole.
The fourth switches 18a to 18d can be turned on reliably. Then, when the load is removed, the first cushion body 12 restores its original shape, so that the strip 19 of each switch can easily restore its original state, thereby ensuring that the OFF operation is performed.

Note that this invention is not limited to the above-mentioned example,
For example, the alarm lamp may be replaced with a buzzer or the like, or the alarm lamp may not be provided. Furthermore, the red LED serving as the second display means may be replaced with a buzzer, or the buzzer may be provided in parallel with the red LED. Also, the switch that turns on when a load is applied to the pine stress is not the pine stress.
It may be provided on the frame of the bed on which the mattress is placed, and there is no limitation in this respect either.

[Effect of idea]

As described above, this invention provides a cushion layer on the upper surface of the spring unit, and provides hard or semi-hard layers on the upper and lower surfaces of this cushion layer, respectively, to apply pressure to the accommodation portion formed in the cushion layer. In addition to accommodating a switch that is turned on, the first and second display sections respectively display whether the switch is in an on state or an off state. Therefore, even if a load is partially applied to the pine stress, the load is distributed over the entire surface of the pine stress by the hard or semi-hard layer on the upper surface of the cushion layer, and is distributed over the entire surface of the pine stress by the hard or semi-hard layer on the lower surface. You can definitely receive it. Therefore, the switch housed in the housing section is compressed by the pair of hard or semi-hard layers and is turned on reliably, and is turned off reliably by the restoring force of the cushion layer when the load is removed. Therefore, it is possible to easily and reliably confirm whether or not there is a patient on the mattress using the display section.
