BEST MODE FOR CARRYING OUT THE INVENTION A security management system proposed by the present application is a central control device 2 installed in a base station 1, connected to the central control device 2 by wire or wirelessly, and in a room separate from the base station 1. 4 and a nurse call terminal 5 installed in the safety management system. This safety management system is at least one sensor provided on the bed 6 in the room 4 and detecting that the care receiver is about to leave the bed 6, and the output of which is connected to the nurse call terminal 5. Sensors 7, 8, 9, 10,
11 and 13, and an infrared CCD camera which is connected to the central control device 2 by wire or wireless and is controlled by an input from the central control device 2, and which is an infrared CCD camera 14 installed in the room 4. Further, the central control unit 2 is provided with a means 16 for displaying an image captured by the infrared CCD camera 14.

By adopting the above configuration, when the care receiver tries to leave the bed without pressing the nurse call, the sensors 7, 8, 9, and 9 indicate that the care receiver is about to leave the bed. 10, 11, 13 sense and transmit to the nurse call terminal 5, which is transmitted to the central controller 2 installed in the base station 1. In the base station 1, the central control device 2 is operated to operate the infrared CCD installed in the room 4.
By activating the camera 14 and displaying the captured image on a display means (for example, a liquid crystal monitor) 16 provided in the central control device 2, the care receiver is leaving or leaving the bed by the sensor. The situation of the bed 6 recognized as having been done can be visually grasped. Thus, when the care receiver is actually going to leave the bed, he can rush from the base station 1 to the room 4 to assist the care receiver's operation and prevent a fall accident or the like from occurring. . On the other hand, when the cared person does not leave the bed, such as when the cared person merely turns over and the sensor has reacted, the operation of the infrared CCD camera 14 is stopped and the sensor is stopped. Is returned to the original state.

In the above configuration, the means (for example, a liquid crystal monitor) 16 for displaying an image captured by the infrared CCD camera 14 provided in the central control unit 2 is installed in the room 4 separate from the base station 1. The output from the nurse call terminal 5 to the central controller 2 is
May be configured to be operable only when is received. For example, the power supply of the liquid crystal monitor 16 is configured to be input only when the central control device 2 receives the output from the nurse call terminal 5. With this configuration, the caregiver at the base station 1 cannot arbitrarily observe the state of the bed 6 in the room 4 with the infrared CCD camera 14, thereby protecting the privacy of the care receiver. In addition to this, it is possible to extend the period during which the electric device components of the liquid crystal monitor 16 can be used, thereby saving power.

Further, a bed 6 in a room 4 separate from the base station 1
At least one or more sensors 7, 8, which detect that the care receiver is about to leave the bed 6.
9, 10, 11, 13; an infrared CCD camera 14 installed in the room 4 whose operation start is controlled by an output from the sensor; and an infrared CCD camera 14 installed in the base station 1 and wired. Or a central control device 2 connected by wireless, and the infrared CCD camera which can be provided in the central control device 2 and starts operating based on a wired or wireless output signal from the infrared CCD camera 14 A security management system may be configured by means (for example, a liquid crystal monitor) 16 for displaying the image captured by 14.

Even with such a configuration, the sensors 7, 8, 9, 1 and 2 indicate that the care receiver is about to leave the bed.
The state of the bed 6 is visually sensed by an image from the infrared CCD camera 14 displayed on the liquid crystal monitor 16 of the central control unit 2 installed in the base station 1 based on the output of the bed 6. You can figure out.

Further, based on an output signal from the infrared CCD camera 14, means for displaying an image provided in the central control unit 2 such as a power supply of a liquid crystal monitor 16 (for example, a liquid crystal monitor) Since the start of the operation of 16 is performed only based on a wired or wireless output signal from the infrared CCD camera 14, the caregiver at the base station 1 can arbitrarily change the state of the bed 6 in the room 4 by the infrared CCD. Observation with the camera 14 is no longer possible, so that the privacy of the cared person can be protected, and the period during which the electric device components of the liquid crystal monitor 16 can be used can be extended to save power.

In the above configuration, the sensor 7,
8, 9, 10, 11, 13
As a configuration for controlling the start of operation of the CD camera 14, the power of the infrared CCD camera 14 is input by the output from the sensor 7 or the like, or the infrared
A configuration in which the D camera 14 is switched on by an output from the sensor 7 or the like can be employed.

If the above-mentioned safety management system of the present invention can be connected not only by wire but also by wireless, it can be used in hospitals such as welfare-related facilities, nursing homes, kindergartens, nurseries, and general homes. The safety management system of the present invention can be easily adopted even in a facility where wired wiring such as an existing nurse call line is not made.

The sensor used in the safety management system of the present invention is a weight sensor 7, which is provided below the mattress 17 of the bed 6 and detects a shift in the weight of the care receiver.
8, an infrared photoelectric sensor 9 (9) installed between the bed head side 6a and the bed foot side 6b to detect the movement of the care receiver;
a, 9b), an infrared pyroelectric sensor 10 installed below the bed 6 for detecting the movement of the care receiver, and a touch sensor 1 installed on the bed shelf 18 for detecting the contact of the care receiver.
1, and one or more of the bed leaving sensors 13 attached to the string member 12 stretched between the bed head side 6a and the bed foot side 6b and sensing the movement of the care receiver. be able to. By using at least one of these sensors, it is possible to grasp that the care receiver is about to leave the bed. Then, if it can be grasped in this way, immediately the infrared CCD
By visually observing the condition of the bed using the camera 14 or by starting the operation of the infrared CCD camera 14 by the output from the sensor related to the care, the care receiver actually leaves the bed. It is possible to accurately recognize whether or not the user is trying to do so. In addition, if a plurality of sensors are used in combination, it is possible to more specifically grasp the state of behavior of the cared person or the state of the bed from the sensing state of each sensor.

The central control device 2 and the nurse call terminal 5 used in the safety management system of the present invention
When the central controller 2 and the infrared CCD camera 14 are connected wirelessly, there is an advantage that it is not necessary to install a wired system. However, in a hospital, there is a limit on the transmission output with respect to the emission of radio waves. Care must be taken regarding the installation of the equipment. Specifically, the transmission burst output 8
It is preferable to set the average output to 10 milliwatts or less, and the central control device 2, the nurse call terminal 5, and the infrared CCD camera 14, which are wirelessly connected,
It is necessary to install it so that the interval is within several tens of meters. Further, in order to eliminate the influence on the medical electrical equipment such as noise mixing and the possibility of malfunction, it is necessary to install these equipments and the medical electrical equipment as far apart as possible.

When the central control unit 2, the nurse call terminal 5, the infrared CCD camera 14 and the like are connected wirelessly, it is advantageous because it is not necessary to carry out new wiring work. In particular, in places such as welfare or nursing homes, kindergartens, nurseries, homes, etc., where there is no limit on transmission output, there is no particular restriction on the installation location,
In such a facility, when there is no wired wiring such as an existing nurse call line, any or all of the central control device 2, the nurse call terminal 5, and the infrared CCD camera 14 are wirelessly connected. It is even more advantageous.

In the above-mentioned safety management system according to the present invention, it is desirable that the infrared CCD camera 14 be provided with an infrared illuminator 19. When the infrared CCD camera 14 is operated to be illuminated by the infrared illuminating device 19, the condition of the bed can be visually grasped even in the nighttime at night, Because of the infrared illumination, the face of the cared person projected by the infrared CCD camera 14 becomes unclear, the outsider cannot identify the cared person, and the privacy of the cared person can be protected. it can.

Embodiment 1 Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. Hereinafter, in order to distinguish a nurse call consciously pressed by a care recipient from a nurse call activated by a sensor that has detected leaving of the care recipient, the former is simply referred to as a “nurse call” and the latter is referred to as a “sensor call”. Call. "

FIG. 1 is a perspective view schematically illustrating a bed 6 in which the safety management system of the present invention is adopted and a room 4 in which the bed 6 is installed. Room 4 separate from base station 1
Is provided with a nurse call terminal 5 and an infrared CCD camera 14 (FIG. 1), which are connected to the central controller 2 installed in the base station 1. The connection method is shown in FIG. As shown in FIG. 4, either a method using wired electric circuits 3 and 15 or a method using wireless communication via radio waves may be used.

Here, the wired connection as shown in FIG. 3 includes a wired line, a nurse call line, and the like, which is advantageous in that the generation of radio interference radio waves can be prevented. On the other hand, the wireless connection as shown in FIG. 4 has the advantage that it is not necessary to newly install a wired system. However, in a hospital, in order to eliminate the influence of radio interference, the above-described output regulation, installation location, etc. Consideration is necessary.

The bed 6 is provided with a sensor described below so as to be able to detect that the care receiver is about to leave the bed.

Below the mattress 17 of the bed 6, weight sensors 7, 8 are installed. These are sensors that sense the shift in the weight of the care receiver. Weight sensors 7, 8
Is a substrate 20, as shown in FIG.
21 is attached to the back surface 20a, 21a using a spring material, the switch is closed when weight is applied, and the switch is opened when weight is not applied;
It is set to make a sensor call when the switch is opened. In actual use, the substrates 20 and 21 are turned over from the state shown in FIG. 2 and the back surfaces 20 a and 21 a to which the weight sensors 7 and 8 are attached are brought into contact with the upper surface of the bed 6.

As shown in FIGS. 3 and 4, the weight sensors 7 and 8 reduce the erroneous operation of the sensors and more accurately recognize that the care receiver is about to leave the bed. It is desirable to install it at a position that supports the shoulder blades and waist. In FIG. 1, the weight sensors are not attached to the substrates denoted by reference numerals 22, 22, and 22, but the substrates 20, 21 to which the sensors 7, 8 are attached.
Are made of the same material so as to have the same height. Thus, the substrates 20, 21, 22, 22,
After arranging the mattresses 22 on the bed 6, the mattress 17 is mounted thereon, and predetermined bed making is performed (FIG. 1). In this state, it cannot be grasped from the outside that the devices such as the weight sensors 7 and 8 are installed.

As described above, the weight sensors 7, 8
Is attached to the back surfaces 20a and 21a of the substrates 20 and 21 using a spring material, and the mattress 1 is placed on the surfaces of the substrates 20 and 21.
Since the weight sensor 7 is mounted, even if the weight sensors 7 and 8 are used, the cared person does not feel uncomfortable and can be used without being noticed by the cared person at all.

The weight sensors 7 and 8 can be connected to the nurse call terminal 5 with a circuit configuration as shown in FIGS. If the two weight sensors 7 and 8 are electrically connected in parallel as shown in FIGS. 3 and 4, this can be sensed when the care receiver gets off the bed 6. In addition, although not shown, if the care receiver is in a sitting position, it can be sensed when connected in series. If the two weight sensors 7 and 8 are electrically connected in series to be able to sense when the cared person is in a sitting position, it is possible to cope relatively quickly, and the cared person can leave the bed. Nurses, caregivers, nurses,
This is effective in preventing a caregiver such as a family from rushing from the base station to prevent a fall accident or the like.

An infrared photoelectric sensor 9 (9a, 9b) is provided between the bed head side 6a and the bed foot side 6b. The infrared photoelectric sensor 9 is composed of a pair of optical sensors of a light emitting / receiving section 9a and a reflecting section 9b.
In the example shown in FIG. 4, a light emitting / receiving section 9a is attached to the bed head side 6a, and a reflecting section 9b is attached to the foot side 6b.
Infrared rays are emitted from the light emitting / receiving unit 9a and reflected by the reflecting unit 9b. Therefore, when there is an obstacle in between, for example, when there is a cared person, the infrared rays are blocked. Therefore, it is set so that the sensor call is performed when the infrared ray is blocked, that is, when the care receiver tries to leave the bed.

An infrared pyroelectric sensor 10 is provided below the bed 6.
Is installed (FIGS. 1, 3, and 4). This is installed so that a sensor call is performed by detecting infrared rays (infrared rays due to body temperature of the legs) emitted from the care receiver's leg. That is, when the care receiver takes his or her legs down to the side of the bed in order to move away from the bed, the infrared rays emitted from the care receiver's legs are detected and a sensor call is performed. Can be. As shown in FIGS. 3 and 4, the infrared pyroelectric sensor 10 is provided with a controller 23, which determines whether or not the signal from the infrared pyroelectric sensor 10 is infrared light generated from a human leg. Is done. Further, a timer 24 is also provided, so that switching for activating the infrared pyroelectric sensor 10 can be performed only at night when there are no visitors or the like.

When the infrared pyroelectric sensor 10 is used, a sensor call is made by detecting when the cared person is in the end sitting position, so that a caregiver such as a nurse, a care worker, a nurse, a family member, etc. Can understand the situation and take action.

The bed fence 18 is provided with a touch sensor 11. This is a sensor that senses that the cared person has come into contact, wraps a thin copper wire around the bed rail 18,
When the care receiver touches this, it operates according to the change in capacitance, and the sensor call is set. As the touch sensor, a touch sensor that has been conventionally developed as an input unit of an environmental control device for a cervical spinal cord injury patient can be used.
It is very convenient because it responds even to a light touch of the care receiver, and is effective for a care receiver who can get up by grabbing on the handrail of the bed.

A bed leaving sensor 13 is attached to a cord member 12 stretched between the bed head side 6a and the bed foot side 6b (FIG. 1). The bed leaving sensor 13 is configured such that a metal plate is attached to a tip side contact portion of a plastic scissor-like member, and a plastic plate is sandwiched between the tip side metal plate and the metal plate. I have. A string member 12 is stretched between the bed head side 6a and the bed foot side 6b, and the string member 12 is sandwiched between the metal plates at the tip end of the clothespin-like member with the plastic plate interposed therebetween. When the care receiver gets caught on the string member 12 in order to leave the bed, the plastic plate is detached from the clothespin-like member, and the tip side metal plates come into contact with each other to perform a sensor call. .

In the case of the leaving sensor 13, a sensor call is performed when the cared person starts moving, so that the caregivers such as nurses, care workers, nurses, and family members can rush immediately, and fall down. It is effective in preventing accidents. In addition, by adjusting the position where the cord member 12 is stretched in various ways, it is possible to cope with a care receiver with various rest levels, and the preparation is simple, so that the sensor is relatively easy to adopt. However, once the sensor call is made, there is a problem that the sensor call continues until a visit is made to the room where the bet is placed and reset, and if the string member 12 is loose, it may not operate. Careful handling is required.

The safety management system according to the present invention comprises:
In order to prevent the occurrence of accidents such as falls of care recipients and infants, the care recipients are automatically replaced when they begin to leave the bed without pressing the nurse call. Since the purpose is to be able to grasp the action at the base station, one or a plurality of the aforementioned sensors can be used in combination. Even if only one sensor is used, a predetermined effect can be exerted. However, by using a plurality of sensors in combination, it is possible to more accurately grasp the operation status of the cared person. For example, two weight sensors 7 and 8 are used so that they can be sensed when the cared person takes a sitting position, and a sensor call is performed when the cared person tries to leave the bed. When the infrared photoelectric sensor 9 (9a, 9b) set to
When the sensor call is performed by the output from both, it can be grasped that the care receiver is in the end sitting position so as to move away from the bed.

When a plurality of sensors are combined as described above, according to the experiment of the inventor, the weight sensors 7 and 8 are most likely to malfunction (a sensor call is performed even though the care receiver is not leaving the bed). Therefore, it is desirable to select this as the center of the combination and combine the weight sensors 7 and 8 with other sensors.

A feature of the safety management system of the present invention is that a video surveillance system using a television camera is combined with the various sensors described above.

That is, when a sensor call is made, by operating the central control unit 2 of the base station 1,
Means for operating the infrared CCD camera 14 installed in the room 4, capturing the state of the bed on which the sensor call has been performed by the infrared CCD camera 14, and displaying the captured image on the central controller 2; For example, LCD monitor 1
6 can be displayed. By visually observing the condition of the bed, whether or not the person is actually leaving the bed, that is, a nurse, a care worker,
Nurses, family members, etc. immediately know whether or not it is necessary to rush to a hospital room, nursing room, living room, bedroom, etc. where a nurse call terminal is installed, and visit that room only when necessary. It can be a system.
As a result, it is possible to quickly visit a sickroom, a nursing room, a living room, a bedroom, and the like only when it is necessary to prevent a fall accident or the like, while a malfunction of the sensor (for example, when the care receiver leaves the bed). Nurse, a malfunction that a sensor call is made,
It can prevent caregivers, caregivers, family members, and other caregivers from visiting sick rooms, nursing rooms, living rooms, bedrooms, etc., and the care recipients may be surprised by unexpected visits by nurses, caregivers, caregivers, family members, etc. And the load on caregivers such as nurses, caregivers, nurses and families can be reduced.

In this embodiment, the power of the liquid crystal monitor 16 is inputted only when the central control unit 2 receives the sensor call, and the caregiver at the base station 1 can arbitrarily enter the bed 6 in the room 4. The state of the infrared CCD camera 14
In order to protect the privacy of the cared person, the LCD monitor 16
This is effective in extending the electrical life of a device that displays an image including the image.

In the present invention, an infrared illuminating device 19 can be attached to the infrared CCD camera 14 (FIG. 1). When the infrared CCD camera 14 is operated, if the illumination is performed by the infrared illumination device 19,
Even when it is dawn at night, the condition of the bed can be visually grasped. Also, because of the infrared illumination, the face of the care-receiver projected by the infrared CCD camera 14 becomes unclear, and the outsider Cannot identify the cared person and protect the privacy of the cared person.

The central control unit 2 used in this embodiment is:
A system in which a sensor call is performed according to the output from the sensors 7, 8, 9, 10, 11, and 13 is incorporated in a parent device of a nurse call system that has been conventionally used, and is connected by wire or wirelessly. While performing output to control the operations of the infrared CCD camera 14 and the infrared illuminating device 19,
Since the monitor 16 serving as an image display means is provided so that an image captured by the infrared CCD camera 14 can be displayed, various configurations can be used as long as these functions can be performed. Although not used in the description of this embodiment, the speaker and / or the microphone 25,
Of course, it is also possible to equip the central control device 2 and the nurse call terminal 5 with 6 so that a conversation can take place between the care receiver and the base station.

It is sent to the central controller 2 of the station 1. The liquid crystal monitor 16 provided in the central control device 2 is configured so that power is input only after receiving an electric signal from the infrared CCD camera 14, and the caregiver at the base station 1 can use the sensor 7 or the like. Only after detecting the movement of the care receiver, the state of the bed 6 in the room 4 can be visually grasped by the infrared CCD camera 14.
With such a configuration, the base station 1 transmits the infrared CC
Since the starting of the D camera 14 cannot be controlled, and the state of the room 4 can be seen only when the care receiver tries to leave the bed, it is preferable from the viewpoint of protecting the privacy of the care receiver. .

Further, the power is supplied to the display means 16 only when the central control device 2 receives the electric signal sent from the infrared CCD camera 14, so that the display means 16 is supplied with power.
There is an advantage that the electrical life of the component displaying the image can be extended.

The central controller 2 has an infrared CCD
When an electric signal is received from the camera 14, it is desirable to make a ringing tone so that the caregiver can be alerted.

In FIG. 5, the sensors 7, 8, 9a, 9b, 1
0, 11 and 13 are connected to the power supply 27 of the infrared CCD camera 14, but the infrared CCD
Any configuration that can start the camera 14 can be employed.

Infrared CCD camera 14 and central controller 2
Are not only wirelessly connected, but also dashed lines 28a, 28a.
A wired connection as shown by b is also possible.

In the configuration of this embodiment, since the output of the sensor 7 and the like is directly connected to the power supply 27 of the infrared CCD camera 14, the nurse call 5 is not installed in the room 4 as in a general home. In this case, there is less need for new wiring and the like. However, a configuration in which the nurse call 5 is installed as shown in FIG. 5 is also possible.

According to the present invention, the 1
Alternatively, the base station 1 can grasp that the cared person is about to leave the bed 6 by using a plurality of sensors, and by operating the central control device 2 of the base station 1 in such a case, the room can be obtained. The infrared CCD camera 14 installed in the apparatus 4 is operated, the state of the bed on which the sensor call has been made is captured by the infrared CCD camera 14, and this is displayed on the central controller 2 by means for displaying an image, for example. By displaying the condition on the LCD monitor 16 and visually observing the state of the bed, it is determined whether the care receiver is actually leaving the bed, that is, the nurse, the caregiver, the nursing mother, the family, etc. It is possible to accurately grasp whether or not it is necessary to rush to a certain room, and to establish a system of visiting that room only when necessary. Thus, when it is necessary to prevent a fall accident or the like, it is possible to immediately visit the room and take necessary measures. On the other hand, it is possible to prevent nurses, caregivers, nursing mothers, and family members from visiting due to malfunction of the sensor, so that the cared person is not surprised by unexpected visits by nurses, nursing staff, nursing mothers, family members, etc. Also, the load on care staff, nurses, family members, etc. can be reduced.

Further, if the liquid crystal monitor 16 provided in the central control device 2 is configured to be activated only when the central control device 2 receives a sensor call, privacy of the cared person can be protected. In addition, the life of the image display electric device including the liquid crystal monitor 16 can be extended.

Further, only when the output of the sensor
The start of operation of the CD camera 14 is controlled, and the operation of the liquid crystal monitor 16 provided in the central control device 2 is started only when the central control device 2 receives an electric signal from the infrared CCD camera 14. Also, the privacy of the cared person can be protected, and the life of the image display electric device including the liquid crystal monitor 16 can be extended.

Further, by connecting the central control unit 2, the nurse call terminal 5, and the infrared CCD camera 14 used in the safety management system of the present invention wirelessly, it is not necessary to set up a wired system, so that the base station and the bed can be connected. The safety management system of the present invention can be easily adopted even in a facility where no wired wiring such as an existing wired line or a nurse call line is provided between the room and the home, and at home.
