Abstract

PURPOSE:To surely send an alarming sound to a nurses' station if the condition of a patient becomes worse and a pushbutton switch is not pushed by making an advance notice lamp flash when a first timer complets counting without being reset, and making a second timer reset at the push of the pushbutton switch. CONSTITUTION:When a patient pushes a pushbutton switch 15 at the sight of the flashing of an advance notice lamp 16, an annunciator control circuit 12 sends a time-clear signal for resetting a value counted by an annunciator five-minutes timer 13 to an initial value, and also changes a patient's abnormality signal S from H level to L level and resets a main-station one-minute timer 4, thereby turning the advance notice lamp 16 off. In this case, the main-station one-minute timer 4 which keeps counting under the control of a main-station control circuit 2 which has received the patient's abnormality signal FS completes counting and stops unless the pushbutton switch 15 is pushed within one minute. Therefore, an alarming-sound generating circuit 3 and an amplifier 5 are operated and send out an alarming sound from a loudspeaker 6, informing a nurses' station that the condition of the patient has become worse.

When a patient enters a predetermined living area such as a washroom in the nurse call device with an alarm function configured as described above, a proximity detector (not shown) is activated to detect that the patient has entered the toilet. When it is detected that the patient has entered the washroom, the motion sensor 29 becomes active, and the output side of the motion sensor 29 is set to L.
Changes from level to H level. When the output side of the moving body sensor 29 becomes H level, the alarm control circuit 28 sends an H level sensing signal FK to the terminal T1 of the nurse intercom base unit 21 via the terminal T2. When the sensing signal FK is input to the terminal T1 of the nurse intercom base unit 21, the base unit control circuit 22 is activated and the base unit 5-minute timer 24 starts counting. When the main unit 5-minute timer 24 counts for 5 minutes, the alarm sound generating circuit 23 is activated, and an alarm sound is sent from the speaker 26 via the activated amplifier 25 to notify the nurse station that the patient's condition has worsened. . In addition,
If the patient moves before the alarm sound is sent out, the sensing signal FK is cut off and the 5-minute timer 24 is reset. When the patient leaves the washroom, the proximity detector is restored and the motion sensor 2
9 returns from the active state to the standby state.

In the nurse call device with an alarm function configured as described above, the 5-minute timer 24 starts counting unconditionally when the patient's condition changes, even if the patient is conscious and there is no need for a nurse call. However, there are drawbacks such as the fact that alarm sounds are often sent out incorrectly.
