Abstract

PROBLEM TO BE SOLVED: To permit relatives and the like to securely confirm the safety of a patient while the video of a photographing machine is prevented from being transmitted to an unspecified third person by transmitting the video of the photographing machine which is previously installed on the calling side thorough the public telephone line when the identification number of the calling side is registered in a registering procedure. SOLUTION: When the telephone set 11 of the patient is called from a video telephone 2 and the telephone set 11 receives an incoming signal, an analysis means 12 analyzes the incoming signal and detects the telephone number of the calling side. A judgment means 14 judges whether the detected telephone number of the calling side is registered in a memory 13 or not. When the telephone number of the calling side is registered in the memory 13, the present video photographed by a camera 15 is transmitted to the calling side through the public telephone line 10. Thus, the relative can recognize the safety of the patient even if the patient is in a state where he cannot respond to the telephone call because of his being taken ill by compulsorily transmitting the video of the camera 15 to the relative.

Confirmation signal transmitting means for transmitting to the calling side via the telephone line 10, and is constituted by a microcomputer or the like. FIG. 2 is a flowchart showing the operation of the state checking device according to the first embodiment of the present invention.

Next, the operation will be described. First, when a relative or the like confirms the safety of the patient or the like, a call is made from the TV phone 2 to the telephone 11 of the patient or the like. Then, when the telephone 11 receives the incoming signal (step ST1), the analyzing means 12
Analyzes the incoming signal to detect the telephone number of the calling side (step ST2).

When the analyzing means 12 detects the telephone number of the calling side, the determining means 14 determines whether or not the telephone number of the calling side is registered in the memory 13 (step ST3). If the determination result of the determination means 14 indicates that the telephone number of the calling side is not registered in the memory 13, the video transmission means 16 determines that the call is a normal telephone which is not related to the safety confirmation. Then, a ringing tone is output from the speaker 17 (step ST4). The following operation in this case is the same as that of a normal telephone, and the description is omitted.

The video transmission means 16 is provided with a judgment means 14.
If the determination result indicates that the telephone number of the calling side is registered in the memory 13, it is determined that the call is a telephone for confirming safety by a relative or the like, and the current image captured by the camera 15 is displayed. The call is transmitted to the calling side via the public telephone line 10 (step ST5). Thereby, regardless of the circumstances of the patient or the like, the image of the camera 15 is forcibly transmitted to the relatives or the like, so that the safety of the patient or the like can be confirmed. That is, if the patient or the like is within the photographing range of the camera 15, even if the patient or the like falls down due to poor physical condition or the like, the safety of the patient or the like can be confirmed from the image of the camera 15. When the patient or the like does not exist within the photographing range of the camera 15, the safety of the patient or the like cannot be directly confirmed, but it can be confirmed that at least the patient does not fall within the photographing range. It is possible to confirm that the patient is out of the office.

The video transmission means 16 is connected to the camera 15
Is transmitted from the speaker 17 for a certain period of time (step ST6). When the patient or the like turns on the safety confirmation switch 18 within a certain period of time in response to the ringing sound of the speaker 17, the confirmation signal transmission means 19 transmits a confirmation signal indicating this to the public telephone line 10.

This allows the relatives to accurately confirm the safety of the patient or the like when the patient or the like is not within the photographing range of the camera 15 and the safety of the patient or the like cannot be confirmed. Even if it is not possible (for example, if it is not clear whether the patient is just sleeping or falling down), the safety of the patient or the like can be surely confirmed by receiving the confirmation signal.

On the other hand, the patient or the like responds to the ringing sound of the speaker 17 within a predetermined time by a switch 18 for confirming the safety.
If the switch is not turned on, the confirmation signal transmitting means 19 causes the speaker 17 to output the ringing sound again for a certain period of time, and confirms whether or not to give the opportunity to turn on the safety confirmation switch 18 again. The signal is transmitted to the calling side via the public telephone line 10. Then, when a response signal to give the opportunity again is transmitted from the relative or the like, the process returns to step ST6, and the same operation is repeated (step S6).
T9). On the other hand, if a response signal to give the opportunity again is not transmitted from the relative or the like, a series of processing is ended (step ST9).
