DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nurse call apparatus, and more particularly to a method of notifying a nurse call base station of a nurse call to a nurse call base station when a call level from the nurse call base station to the nurse call base station is low. Related to a nurse call device that can be used.

[0002]

2. Description of the Related Art Conventionally, a nurse call apparatus shown in FIG. 4 has been proposed. In the nurse call device, a speaker 61a, a microphone 61b, a nurse call handset SB ₁ provided with a grip button 61c is connected with the nurse call master unit MB through a set corridor adapter RB _1.

[0003] When the user presses the grip button 61c of the nurse call handset SB _1, emission of nurse call base unit MB diode 6
2a blinks. Channel selection button 62b on nurse call master unit MB
When the user presses the button, a nurse call can be made with the handset 63. Microphone 61b because patients using nurse call handset SB ₁ is sleeping on the bed is at a substantially constant distance (30cm~1m) from the patient, Boryuumu for nurse call parent device MB is received sound provided in the main body 64 And listening at an appropriate volume.

[0004] audio signal collected by the microphone 61b is amplified and sent to a nurse call base unit MB through a set corridor adapter RB _1. As shown in FIG. 5, (and 4 the number of identical disease indoor handset for explanation) nurse call handset SB ₁ to SB _4, set corridor adapter RB ₁ ~RB ₃ (set corridor adapter for explanation When the number is set to 3) and connected to the nurse call base unit MB, the nurse call base unit MB has 12 light emitting diodes 62a (4 × 3 = 1 in the same hospital room).
2) and 12 tuning buttons 62b corresponding to the light emitting diodes 62a are mounted.

[0005]

In such a nurse call device, depending on the condition of the patient, the voice may be low,
In extreme cases, no voice is heard, and the patient's voice may not be heard by the nurse call master unit.Nearby patients can report anything to the nurse call master unit in place of the calling party. However, there is a drawback that it is not possible to cope with it.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks, and the condition of a poor patient is transferred from a nurse call slave unit provided in the same hospital room to a nurse call master unit.
