Abstract
A kind of patient's urgent help caller, belongs to electronic technology field, adopts and calls for help trigger circuit, sound light alarming circuit and audio amplification output circuit composition.Call for help trigger circuit by calling for help switch S 2, trigger switch S3, transistor V1 ~ V3 forms, sound light alarming circuit is by IC1, resistor R6 and light emitting diode VL1, VL2 forms, audio amplification output circuit is by IC2, super loudness piezoelectric buzzer HA, diode VD2 and resistor R7 forms, when user's normal activity, power switch S1 and calling for help switch S 2 are connected, trigger switch S3 is in off-position, V1 is in saturation conduction state, V2 and V3 only carries, IC2 and IC3 does not all work, piezoelectric buzzer HA is noiseless, light emitting diode VL1 and VL2 does not work, after user's morbidity falls down to the ground, S3 connects, V1 only carries, V2 and V3 conducting, IC2 and IC3 is energized work, piezoelectric buzzer HA sends the sound of blowing a whistle of ambulance, send diode VL1 and VL2 to light simultaneously.
Description
Technical field
The utility model belongs to electronic technology field, is a kind of pocket rescue beacon.
Background technology
At present, have a heart disease, cerebral hemorrhage, the disease such as hypertension people get more and more, this kind of disease is and danger be easy in time cause life danger if can not give treatment to once outbreak.Generally can be provided with active rescue beacon heavily protecting in ward of hospital, and this type of disease is not when falling ill, do not affect daily life and the outdoor activity of patient, so do not need long hospitalisation, and not at hospital's long-term inpatients, if household can not accompany for a long time, it is difficult to again the timely treatment obtaining surrounding population when burst disease, thus brings fatal risk.
Summary of the invention
The technical problems to be solved in the utility model be openly a kind of can by sending blow a whistle sound and the red flashing light warning thus cause people around to note of ambulance, the danger avoiding patient to fall ill nobody shows any interest in when falling down to the ground.It is be made up of calling for help trigger circuit, sound light alarming circuit and audio amplification output circuit that this patient's urgent help caller is formed.Call for help trigger circuit by calling for help switch S 2, trigger switch S3, transistor V1 ~ V3 form.Sound light alarming circuit is made up of sound effect integrated circuit IC1, resistor R6 and light emitting diode VL1, VL2.Audio amplification output circuit is made up of Audio power amplifier boost module IC2, super loudness piezoelectric buzzer HA, diode VD2 and resistor R7.When user's normal activity, power switch S1 and calling for help switch S 2 are connected, trigger switch S3 is in off-position, V1 is in saturation conduction state, V2 and V3 only carries, IC2 and IC3 does not all work, piezoelectric buzzer HA is noiseless, light emitting diode VL1 and VL2 does not work, after user's morbidity falls down to the ground, S3 connects, V1 only carries, V2 and V3 conducting, IC2 and IC3 is energized work, piezoelectric buzzer HA sends the sound of blowing a whistle of ambulance, send diode VL1 and VL2 to light simultaneously, this rescue beacon is installed simple, easy to use, safe and reliable, it is the selection that each patient is desirable.
Accompanying drawing illustrates:
Fig. 1 is electronic-circuit diagram of the present utility model.
Embodiment:
The utility model is by patient's distress call trigger circuit, sound light alarming circuit and audio amplification output circuit composition, call for help trigger circuit by calling for help switch S 2, trigger switch S3, transistor V1 ~ V3 forms, sound light alarming circuit is by sound effect integrated circuit IC1, resistor R6 and light emitting diode VL1, VL2 forms, audio amplification output circuit is by Audio power amplifier boost module IC2, super loudness electric buzzer HA, diode VD2 and resistor R7 forms, when user's normal activity, power switch S1 and calling for help switch S 2 are connected, trigger switch S3 is in off-position, V1 is in saturation conduction state, V2 and V3 only carries, IC2 and IC3 does not all work, piezoelectric buzzer HA is noiseless, , light emitting diode VL1 and VL2 does not work, after user's morbidity falls down to the ground, S3 connects, V1 only carries, V2 and V3 conducting, IC2 and IC3 is energized work, piezoelectric buzzer HA sends the sound of blowing a whistle of ambulance, send diode VL1 and VL2 to light simultaneously, " rescue " and " medicine is in box " printed words on rescuring device panel are illuminated, this rescue beacon is installed simple, easy to use, safe and reliable, it is the selection that each patient is desirable.
