Abstract

PURPOSE: To infer the loitering of a patient beforehand by detecting that the patient strides over a bed fence. CONSTITUTION: In a rising and lowering type full surface fence 2 in a bed 1, the upper half part side is inclined so as to be adjacent to the floor part 5 inside of the bed 1, and a plate member 7 having a see-through window 6 is installed thereto. A contact type-sensing sensor 8 is installed to the upper side in a position corresponding to the leg side from the waist of the full surface fence 2. An erroneous alarm caused by a patient's erroneous touch in sleeping is reduced, and the loitering of the patient out of the bed can be inferred beforehand. A sufficient monitoring effect can be provided even in a shorthanded time by utilizing a nurse calling means.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dementia patient bed capable of detecting wandering of a patient suffering from dementia.

[0002]

2. Description of the Related Art At present, Japan is facing an unprecedented aging society, and the number of elderly people who are hospitalized for a long time is increasing. Many elderly people suffer from dementia, which is a great burden for nursing care. Therefore, in hospitals, in order to reduce the burden on caregivers and the like, measures have been taken in terms of equipment and facilities.

[0003]

For example, a patient with dementia may get out of bed at night and wander around, which is dangerous and annoying to other patients. However, due to lack of manpower such as nurses,
Since it is difficult to monitor all the time, there has been considered a method of providing some kind of detecting means on the bed and transmitting it to a nurse center or the like for intensive monitoring.
The present invention has been proposed from such a viewpoint,
An object of the present invention is to provide a dementia patient bed by detecting when the patient tries to get over the bed, thereby allowing the patient to be aware of the fact that the patient is leaving the bed and wandering around.

[0004]

In order to solve the above-mentioned problems, the present invention provides a bed with a full-face fence that can be stored under the floor on the side surface of the bed. It is characterized in that a contact-type sensor is provided in a place that is out of reach when lying down. In the above-mentioned configuration, the upper half of the full-face fence is inclined so as to be close to the inside of the floor. Further, it is characterized in that the upper half portion of the entire surface fence is made of a transparent member.

[0005]

[Function] When a patient raises his / her upper body from the floor and tries to get off the bed after getting over the side frame, there is a high probability that the contact-type sensor provided at the top of the full-scale fence will touch the hand or body. The detection signal from the type detection sensor can be transmitted to a nurse center by, for example, a nurse call line, and by an appropriate alarm notification means,
You can catch wandering. It should be noted that the contact-type sensor is at least not reachable even when the patient extends his / her hand when the patient is lying on the floor in a normal position. False alarms can be reduced.

[0006]

The bed for dementia patients according to the present invention will be described below with reference to the accompanying drawings. The bed 1 shown in FIG. 1 is provided with a lifting type full-face fence 2 on the bedside side. This whole fence 2
Is held by the link mechanism 4 and an appropriate fixing mechanism (not shown) on both longitudinal side ends of the bed frame 3 so as to project and to be stored vertically in the bed frame 3 (see FIG. 2). Further, the full-face fence 2 has a shape in which the upper half side is inclined so as to be close to the inside of the floor portion 5 of the bed 1. Further, a transparent window 6 which is cut out in a rectangular shape is formed on the upper half portion side of the entire surface fence 2, and the transparent plate member 7 is transparent.
(For example, a transparent or translucent glass plate, a plastic plate) is attached. This is so that the state of the patient can be observed from a distant position. A contact-type sensor 8 is attached to the upper side of the entire surface fence 2 corresponding to the waist to the leg side (see FIG. 3).

The link mechanism 4 has unequal length links 4a and 4b rotatably attached to both end surfaces of the bed frame 3 on the longitudinal side. Of the links 4a and 4b, the lower link 4b is set to have a shorter dimension than the upper link 4a, and the whole surface fence 2 is projected and supported above the floor 5 by these links 4a and 4b. At this time, the lower half of the full-face fence 2 is supported vertically (Fig. 4).
reference). In addition, the link mechanism 4 includes the entire fence 2 and the floor 5
The upper half of the full-face fence 2 is made to be close to the side surface of the bed frame 3 when it is stored downward (see FIG. 5).

Next, the contact-type sensor 8 provided on the upper side of the full-scale fence 2 at a position corresponding to the waist to the leg side will be described. The contact-type sensor 8 has a known structure. The detection signal from the contact-type sensor 8 is incorporated into a signal processing circuit (not shown) of a control box (not shown).
The signal processing circuit of the control box is
The circuit is configured so that the detection signal from the contact type detection sensor 8 is transmitted to the nurse center via the nurse call line. Further, in the signal processing circuit in the control box, the detection signal of the patient by the contact type detection sensor 8 is
It can be configured to transmit a signal to the nurse center when the patient is actually trying to get over the full fence 2 by checking whether it continues for a predetermined time (for example, 5 seconds), and prevent misjudgment as much as possible. can do.

In the dementia patient bed as described above, when the patient is lying on the floor 5, the full-scale fence 2
Is projected on the bed frame 3. On the other hand, when the full-scale fence 2 is stored under the bed frame 3, the upper half of the full-scale fence 2 is close to the side surface of the bed frame 3, and there is no risk that a patient with dementia will thrust his head in between. No (see FIGS. 2 and 5). Full fence 2 when the patient is sleeping
Since the see-through plate member 7 is provided in the upper half part, the state of the patient can be observed from a distant position. Even if the patient reaches for the full-scale fence 2 and reaches the full-scale fence 2 in this sleeping state, the contact-type sensor 8 is not provided on the upper side of the position of the full-scale fence 2 that has reached, so at least,
When sleeping in a normal posture, there is little risk of unintentionally touching the contact-type sensor 8, and false alarms can be reduced accordingly (see FIG. 6).

When the patient raises his / her upper body, the lumbar region is placed on the floor 5
In the center (see FIG. 7). Therefore, the hand of the patient reaches the upper part of the entire surface fence 2 provided with the contact-type sensor 8, so that the contact-type sensor 8 can detect such a state. This means that the fact that the patient woke up in the upper body during bedtime was already detected at this stage, considering that it was the act of initiating to wander, and the nurse can promptly respond. As described above, even if the patient's hand does not touch the contact-type detection sensor 8 and tries to get over the full-scale fence 2, the foot or body touches the upper portion of the full-scale fence 2 provided with the contact-type detection sensor 8. The probability of pressing is high (see FIG. 8), and the detection signal from the contact-type detection sensor 8 is extracted, and this detection signal reaches the nurse call line via the signal processing circuit of the control box 9 and is transmitted to the nurse center. It is possible to detect in advance that the user is about to wander by using an appropriate alarm notification means.

[0011]

As described above, according to the present invention, when a patient raises his / her upper body from the floor, tries to get over the side frame and gets out of bed, the contact-type sensor provided on the upper surface of the full-scale fence is used. Since there is a high probability of touching the hand or body, the detection signal from this contact-type sensor can be transmitted to the nurse center by, for example, a nurse call line, and it is possible to detect that the person is trying to wander by an appropriate alarm notification means. can do. It should be noted that the contact-type sensor is at least not reachable even when the patient extends his / her hand when the patient is lying on the floor in a normal position. False alarms can be reduced, and wandering can be detected in advance by using the nurse call means, so that a sufficient monitoring effect can be achieved even when manpower is low.
