Hereinafter, embodiments of the present invention will be described based on the drawings. Figure 1 shows the non-contact type of this example. Example of applying the switch to an emergency call switch 1 installed in a hospital room, etc. 2 is a diagram showing an oxygen sensor 2 disposed at the tip of the emergency call switch 1. ing. The emergency call switch 1 has an oxygen sensor 2 located near the mouth of the patient 3. In advance, attach the mounting arm 5 to the appropriate place on the bed 4 in the hospital room so that the and is connected to a nursing center within a hospital via wiring 6 (see Figure 2) is connected to a ring bell, etc. In this case, the acid of the emergency call switch 1 By adjusting the mounting angle of the mounting arm 5, the elementary sensor 2 can be attached to the mouth of the patient 3. It can be set at a desired position nearby. Lying down on bed 4 in the hospital room In the event of an emergency where patient 3 requires nursing care or treatment, the For example, when calling a nurse at a nursing center, turn off the emergency call switch 1. Activate the emergency call switch 1 by intentionally blowing exhaled air onto the sensor 2. state, and the call buzzer at the nurse center in the hospital sounds. Ru.

[0008] Here, to explain the operation of the emergency call switch 1 with reference to FIG. Blow exhaled air into the oxygen sensor 2 of the emergency call switch 1, which is set near the mouth. If the oxygen concentration around the oxygen sensor 2 is higher than the normal atmospheric oxygen concentration (approximately 21%) As a result, the output of oxygen sensor 2 also decreases. When the output drops to a preset level, emergency call switch 1 is activated. The stored contacts are set to be in a conductive state. This allows emergency call A call buzzer 7 in the nurse center is activated via the wiring 6 connected to the switch 1. It moves and makes noise. In this case, the oxygen sensor 2 The contact point of the emergency call switch 1 is in a conductive state. The output level for the It is decided according to the characteristics of the service. On the other hand, patient 3 is connected to oxygen sensor 2. If you do not exhale or if the output of oxygen sensor 2 exceeds the predetermined level. (After patient 3 exhales into oxygen sensor 2, the oxygen concentration around oxygen sensor 2 decreases. If the oxygen concentration becomes the same as that in the atmosphere), a built-in emergency call switch 1 will be activated. Since the contact point is in a non-conducting state, the calling buzzer 7 does not sound. There is.

[0009] Next, the operation of the emergency call switch 1 of this embodiment with the above configuration will be explained based on FIG. explain. First, check the mounting angle of the mounting arm 5 that supports the emergency call switch 1. By adjusting the oxygen sensor 2 of the emergency call switch 1, the oxygen sensor 2 of the emergency call switch 1 can be For example, if you are lying down on your side and have a disability in your hands, arms, or throat (speech organ), you are unable to press the button. The device is placed near the mouth of patient 3, who is unable to move or speak. Set in advance. In an emergency when Patient 3 needs to seek care, leave the room. If you want to call a nurse who is located at a nursing center that is located a short distance away, S1), the oxygen sensor 2 of the emergency call switch 1 set near the mouth Breathe out toward the patient (step S2). As a result, the area around the oxygen sensor 2 The oxygen concentration is lower than the normal atmospheric oxygen concentration (approximately 21%), and the oxygen sensor 2 When the output drops to a predetermined level (step S3), the emergency call switch is activated. The contacts built into the switch 1 become conductive (step S4). As a result, the contact A call to the nurse center is sent via wiring from the emergency call switch 1 that has become conductive. Since a signal is sent to the calling buzzer 7, the calling buzzer 7 sounds (step S 5). As a result, the nurse in the nurse center can receive an emergency call from patient 3 in the hospital room. You can instantly know what you have done.
