2. Description of the Related Art For example, in a nursing home for the elderly, patients sleep on their nursing beds. At that time, some patients may fall out of the nursing bed and try to wander while sleeping. Therefore, conventionally, a caregiver monitors each patient by regularly looking around to prevent such wandering. Alternatively, the patient may accidentally fall from the care bed. When such a fall occurs, a fracture accident occurs. Against this, conventionally, a caregiver monitors each patient periodically to prevent such a fall.

[0003]

According to the above-mentioned conventional configuration, there are the following problems. That is, as described above, a patient sleeping on the nursing bed may get out of the nursing bed and try to wander, or the patient may inadvertently fall from the nursing bed. At this time, it is only necessary to be able to prevent this by regular monitoring of the caregiver, but it is not sufficient at present, and the actual situation is that the occurrence of a fracture accident due to wandering or falling has not been sufficiently prevented.
In response to this, for example, it is conceivable to increase the number of times of monitoring, but this would impose a heavy burden on the caregiver.

[0004] The present invention has been made based on such a point, and an object thereof is that a patient tries to get out of the nursing care bed and wander around, or to inadvertently drop from the nursing care bed. It is an object of the present invention to provide a nursing care system capable of instantly detecting and notifying such a case when it exists, and promptly taking an appropriate treatment.

[0005]

To achieve the above object, a care system according to claim 1 of the present invention is attached to a care bed and detects that a patient is going out of the care bed or falling. Detecting means, a camera for photographing the nursing bed and its vicinity based on the detection signal from the detecting means, and the camera disposed at a location remote from the nursing bed and based on the detection signal from the detecting means. And a warning output unit that is installed at the same place as the monitor and outputs a warning based on a detection signal from the detection unit. According to a second aspect of the present invention, in the nursing care system according to the first aspect, a signal detected by the detecting means is wirelessly transmitted to a remote place where the monitor and the alarm output means are installed. It is assumed that.

That is, in the case of the nursing care system according to the present invention, for example, when the patient on the nursing care bed tries to get out of the nursing care bed or falls carelessly, the detection means detects and detects this. Output a signal. The camera is activated based on the detection signal output from the detection means. With this camera, the care bed and its surroundings are photographed. The captured image is displayed on a monitor installed at a remote location. At the same time, an alarm is output by the alarm output means. Therefore, the caregiver waiting at the remote place first looks at the monitor alerted by the output of the alarm by the alarm output means. Then, it is confirmed by the image projected therefrom that the patient is about to get out of the nursing care bed or is dropping carelessly. After that, he will rush to the site and take necessary measures promptly.

The pilot lamp 27a is turned on to blink the lamp. Further, the monitor 23 is turned on. As a result, the care bed 1 and its surroundings are photographed by the camera 21 and displayed on the monitor 23. The caregiver waiting in the monitoring room recognizes that an emergency has occurred by blinking the pilot lamp 27a, and immediately looks at the monitor 23. Thereby, the state of the nursing bed 1 and the vicinity thereof is confirmed, and the train is rushed to the site.

The camera 21 and the monitor 23 are turned off after a lapse of a preset time. Therefore, if
It is expected that the camera 21 and the monitor 23 will be off when returning after the caregiver is absent. However, even in this case, since the pilot lamp 27a is blinking, the caregiver can know that an emergency has occurred, so that if the return button 27b is pressed, the camera 21 and the monitor 23 will be reset. Turn it on to check the situation at the site.

According to the present embodiment, the following effects can be obtained. First, it is possible to early detect a patient's escape from the care bed 1 or an inadvertent fall while staying in a monitoring room installed in a remote place, thereby preventing the patient from wandering. It is possible to prevent the occurrence of a fracture accident due to inadvertent dropping. When the patient does not try to get out of the bed or drop carelessly, the monitoring camera 21, the monitor 23, and the pilot lamp 27a are both off, so that compared to a case where the patient is constantly functioning. Power consumption can be reduced. Surveillance camera 21
In other cases, signals are transmitted and received wirelessly between the site and the monitoring room, so that the configuration is simplified, for example, wiring is unnecessary. Since the detecting means 3 and 3 are provided on the left and right sides of the nursing bed 1, it is possible to surely detect which side of the nursing care bed 1 falls or falls. or,
Even if the camera 21 and the monitor 23 are turned off when the caregiver is absent and returned when an emergency occurs, the occurrence of the emergency can be known because the pilot lamp 27a is on. By pressing the return button 27b, the camera 21 and the monitor 23 are turned on again, and the situation at the site can be checked.
