A wireless signal can be transmitted from the transmitting unit to a receiving unit mounted on a wall or ceiling, and a nurse station can be called. Further, since the transmitting unit transmits a directional radio signal, the signal does not spread, and the influence on medical equipment and the like can be extremely reduced. In addition,
The call button is coded so that you do not lose track of it.

[0010] The paging apparatus according to the present invention is characterized in that the directional signal transmitted from the transmitting unit is an optical signal.

In the paging apparatus according to the present invention, since the directional signal transmitted from the transmitting unit is an optical signal,
It is possible to prevent the diffusion of the optical signal in a direction other than the direction in which the light emitting element of the transmission unit faces.

Further, the paging apparatus according to the present invention is characterized in that the transmitting unit is installed on the bed, and the power of the transmitting unit is supplied from a power supply unit provided in the driving unit of the bed, so that the transmitting unit can be moved together with the bed. And

In the paging apparatus according to the present invention, the transmitting unit is attached to the bed, and the power of the transmitting unit is supplied from the power supply unit (for example, an AC outlet) of the bed driving unit (for example, the vertical driving unit). Can be freely moved together with the bed without any operation on the transmission unit when moving.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a bed layout of a paging apparatus according to the present invention. In FIG. 1, a bed 7 is arranged in a hospital room 15 so that a longitudinal direction is perpendicular to one surface of a wall 9.
A side is mounted with a motor-driven drive unit 10 that can move the upper body up and down when lying down.

The drive unit 10 includes a main unit composed of a motor and a motor drive circuit, a power outlet 11 constituting a power supply unit for supplying power to other electric equipment, and a power supply unit for supplying 100 V AC power to the main unit. And an AC cord 12 connected to a power outlet 13 provided on a lower wall surface of the wall 9.

A transmission unit 3 of the paging device 1 is provided at a predetermined position (eg, a longitudinal partition plate) of the bed 7.
Is installed. The calling device 1 includes a calling button 2, a transmitting unit 3, a code 4 for connecting the calling button 2 and the transmitting unit 3, and an AC code 5 for supplying 100V AC power to the transmitting unit 3.

Since the AC cord 5 is connected to a power outlet 11 provided in the drive unit 10, when the drive unit 10 is supplied with 100V AC power via the AC cord 12, the transmission unit 3 is also supplied with 100V AC power. Is done.

Therefore, when moving the bed 7,
AC power of the drive unit 10 from the power outlet 13 of the wall 9
By unplugging the cord 12 and plugging the AC cord 12 into another power outlet 13 after moving, the transmitting unit 3 can be freely moved together with the bed 7 without any operation for the transmitting unit 3 and the transmitting unit 3
Can be supplied with AC 100V power.

The call button 2 of the call device 1 comprises a small and lightweight call button / make switch having a normal break contact structure, and is in a make state when the patient presses the call button to call a nurse on the bed. Then, a make signal (electrically on) as transmission information is supplied to the transmission unit 3 via the cord 4 of the two-core cable. The call button 2 is connected to the cord 4, and the patient can operate the cord 4 from any position on the bed 7 by setting the cord 4 to an appropriate length. The cord 4 is curled or provided with a winding mechanism on the side of the transmission unit 3 so that the cord 4 is easy to use and easy to handle, so that the call button 2 is not lost.

The transmitting unit 3 corresponds to the bed 7,
For example, a memory such as a ROM in which a coded code is stored in advance,
It is composed of a light emitting element 3A such as a modulator and a light emitting diode (LED). When a make signal (call information) is supplied in response to the pressing of the call button 2, a predetermined coded code is optically modulated. An optical signal Ls (wireless signal) having a high directivity is transmitted from the light emitting element 3A to a light receiving element 6A including an optical sensor of a receiving unit 6 installed on the ceiling 8 of the sickroom 15.

Since the radio signal transmitted from the transmission unit 3 is generated as an optical signal having high directivity, the diffusion of the optical signal Ls can be prevented except in the direction in which the light emitting element 3A is directed. The effect can be made very small.

Note that the light emitting element 3A is provided with an angle adjusting mechanism so that the light signal Ls is transmitted even when the bed 7 is moved.
So that it can be reached at the shortest distance.

The receiving unit 6 comprises a light receiving element 6A such as an optical sensor, a demodulator, an amplifier and the like. After receiving the optical signal Ls transmitted from the light emitting element 3A of the transmitting unit 3, the receiving unit 6 converts the optical signal Ls into a bed. The signal is demodulated into a signal of a coded code corresponding to 7, and this signal is transmitted to a master unit (monitor) installed in a nurse station via a wire.

The receiving unit 6 is installed at a place where there is no object that blocks the optical signal Ls from the transmitting unit 3 such as the ceiling 8 or the upper part of the wall 9.

[0025]

According to the present invention, the paging apparatus according to the present invention includes a radio transmission unit and a paging button connected to the transmission unit by a cord, so that the patient can keep the cord within a range where the cord can be extended. By simply pressing a light call button from the position, a wireless signal is transmitted from the transmitting unit to a receiving unit mounted on a wall or a ceiling, and a nurse station can be called.

Further, since the directivity signal transmitted from the transmission unit is an optical signal, it is possible to prevent the diffusion of the optical signal in a direction other than the direction in which the light emitting element of the transmission unit is directed, and to transmit the signal to medical equipment or the like. The effect can be made very small.

Further, the transmitting unit is mounted on the bed, and the power of the transmitting unit is supplied from a power supply unit (for example, an AC outlet) of the bed driving unit (for example, the vertical driving unit). It can be moved freely with the bed without any work.
