Abstract

PROBLEM TO BE SOLVED: To surely detect a patient going out by a system which detects a dementia patient, etc., wandering in a hospital, facilities, a house, etc., and going out of a room. SOLUTION: People other than patients put on a detected member 5 which is made of a magnetic body and when both an infrared sensor 4 and a magnetic sensor 5 detect it in a doorway 2 of the hospital 1, an alarm generating means 7 generates no alarm and when only the infrared sensor 4 detects it, an alarm is generated; and this device eliminates the need to make a patient put on the detected member 5, and the patient never takes the detected member 5 off, so that the outgoing of the patient can securely be detected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for detecting that a dementia patient or the like wanders a hospital, facility, house or the like and goes out of the room.

[0002]

2. Description of the Related Art In recent years, the number of patients with dementia has been increasing, and there is a problem that patients wander around in hospitals, nursing homes, etc. and get lost or cause an accident. It is necessary to have a system that can detect and notify nurses and staff.

Conventionally, in this system, a magnetic sensor is provided at the entrance and exit, a card that generates magnetism is attached to the patient as a member to be detected, and the patient is recognized only when the magnetic sensor detects the card. Then, there is a thing to notify by issuing an alarm to nurses and staff.

[0004]

However, the above-mentioned conventional configuration has a problem that the mounted member to be detected is removed by the patient and cannot be detected even when the patient goes out.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a detection system for surely detecting the outing of a patient.

[0006]

In order to achieve this object, a moving object detecting device of the present invention includes a first detecting means for detecting a moving object and outputting a first detection signal, and the moving object. Second detection means for detecting the mounted member to be detected and outputting a second detection signal, and an alarm when the first detection signal is received and the second detection signal is not received It is provided with an alarm generating means for emitting.

[0007]

According to this structure, a member other than the patient is attached to the detected member to distinguish the patient from the person other than the patient, the first detecting means detects the moving object, and the second detecting means detects the moving object. Since the alarm is issued when the detecting means does not detect the member to be detected, it is possible to reliably detect the outing of the patient.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a hospital room, 2 is an entrance / exit of a hospital room, 3 is a human, 4 is an infrared sensor which sends an infrared detection signal to an alarm generating means 7 when the human 3 is detected at the entrance / exit 2.
Reference numeral 5 denotes a member to be detected made of a magnetic material attached to the human 3, 6 denotes a magnetic sensor for detecting the member 5 to be attached to the human 3 at the doorway 2 and sending a magnetic detection signal to the alarm generating means 7, Reference numeral 7 is an alarm generation means for receiving an infrared detection signal from the infrared sensor 4 and a magnetic detection signal from the magnetic sensor 6 and generating an alarm when a predetermined condition is satisfied.

Next, the operation of the moving object detecting device having the configuration shown in FIG. 1 will be described. The alarm generation condition of the alarm generation means 7 is such that an alarm is generated when only the infrared detection signal from the infrared sensor 4 is detected, and the detected member 5 made of a magnetic material is attached to a person other than the patient. An infrared sensor 4 detects a person 3 who exits the entrance / exit 2 of the hospital room 1 and sends an infrared detection signal to the alarm generating means 7. When the person 3 is a person other than the patient, the magnetic sensor 6 detects the member to be detected 5 mounted and sends a magnetic detection signal to the alarm generating means 7. In this case, the alarm generating means 7 issues an alarm. Does not occur. When the human 3 is a patient, the magnetic sensor 6 does not detect the member to be detected. In that case, the alarm generating means 7 generates an alarm to notify the nurse, staff, etc. that the patient has gone out. In such an apparatus, it is not necessary to attach the member to be detected to the patient, and therefore the patient does not remove the member to be detected, so that the outing of the patient can be reliably detected.

When the patient goes out with a person other than the patient (for example, a doctor), it is not necessary to issue an alarm. Therefore, several seconds before and after the alarm generating means 7 detects only the infrared detection signal (for example, 1 If a magnetic detection signal is received within 10 seconds, it is possible not to generate an alarm.

In order to prevent an alarm from being issued when a patient enters the room alone, two sets of infrared sensors and magnetic sensors are installed along the traveling direction of the entrance and exit, respectively, and the direction in which the patient goes out, that is, The alarm can be issued only when the indoor set detects first and then the outdoor set detects.

Although an infrared sensor for detecting infrared rays is used as a sensor for detecting humans, any sensor such as an optical sensor for detecting humans may be used.

Further, although the member to be detected for distinguishing between the patient and the other person is the magnetism generating member and the magnetic sensor is used as the sensor for detecting the member to be detected, if it can be distinguished from the sensor for detecting the human being, Others (optical sensor etc.) may be used.

Further, the alarm is not limited to the alarm bell, and may be a message to a pager of a nurse or the like, or may be displayed in a room where the nurse or the like stands by.

Further, the moving object detection device can be installed in a plurality of rooms for centralized management.

Further, it can be used not only in hospitals but also in facilities or homes such as nursing homes.

[0018]

As described above, according to the present invention, when a person other than a patient is equipped with a member to be detected and no human and the member to be detected are detected, no alarm is generated and only the person is detected. Since the alarm is generated when the member is not detected, it is not necessary to attach the detected member to the patient, and therefore the patient does not remove the detected member. it can.
