Embodiment Construction

[0009] In order to further illustrate the present invention, further description is given below in conjunction with the accompanying drawings:

[0010] like figure 1 As shown, a heart disease monitoring alarm device with high anti-interference sensitivity of the present invention includes a pulse detection circuit, a monostable trigger circuit, an alarm circuit and an audio circuit; the pulse detection circuit is composed of a probe MIC, a resistor R1 and a capacitor C1 , the probe MIC and the resistor R1 are connected in series with the two poles of the power supply;

[0011] The monostable trigger circuit is composed of triode T1, trigger TC1, resistor R2, capacitors C2, and C3. The base of triode T1 is connected to pin 2 of trigger IC1, and connected to probe MIC through capacitor C1. The emitter of triode T1 Connect with pin 7 and pin 6 of trigger IC1, connect resistor R1 and pin 8 and pin 4 of trigger IC1 through resistor R2, and connect collector and probe MIC with pin...

Abstract

The invention discloses a heart disease monitoring alarm with high anti-interference sensitivity. The heart disease monitoring alarm comprises a pulse detecting circuit, a mono-stable trigger circuit, an alarm circuit and an audio circuit and is characterized in that the pulse detecting circuit comprises a probe MIC, a resistor R1 and a capacitor C1, and the probe MIC is serially connected with the resistor R1 and then directly connected with two poles of a power supply, the probe comprises a capacitive electret microphone and a stethoscope head, a rubber tube is arranged on the stethoscope head, and the capacitive electret microphone is arranged in the rubber tube; the mono-stable trigger circuit comprises a triode T1, a trigger IC1, a resistor R2, a capacitor C2 and a capacitor C3, the base of the triode T1 is connected with the pin 2 of the trigger IC1 and connected with the probe MIC through the capacitor C1, and the transmitter of the triode T1 is connected with the pin 7 and pin 6 of the trigger IC1. The heart disease monitoring alarm is high in sensitivity, simple in structure, convenient to carry and low in cost.

Description

technical field [0001] The invention relates to a heart disease monitoring and alarm device capable of preventing interference and having high sensitivity. Background technique [0002] Heart disease seriously affects people's life and health. Many people have a heart attack unknowingly, so that rescue is ineffective and dies. The heart disease monitoring alarm is to issue a warning when a person's heart rate just appears irregular or stops suddenly, reminding the user that there has been a heart problem, and they should take a rest or seek medical treatment immediately to prevent loyalty in the first place. The existing heart disease monitoring alarm has low sensitivity, complex structure, inconvenient portability, high cost, and is not suitable for mass production and popularization. Contents of the invention [0003] In order to solve the above-mentioned existing shortcomings, the main purpose of the present invention is to provide a practical heart disease monitoring ...
