Embodiment Construction

[0014] The invention includes a contact electrode, an electrocardiogram measuring circuit, an A / D converter, a single chip microcomputer, a keyboard, a display unit, a storage unit, a bluetooth module and the like. See the specific structure figure 1 .

[0015] Contact electrodes are two exposed electrodes of corrosion-resistant metal materials. When measuring, the user holds the device with one hand and touches one of the electrodes, and the other electrode can touch the chest, the palm of the other hand, or the lower limbs to complete the measurement. The two electrodes are respectively connected to the ECG measurement circuit, and the ECG measurement circuit completes the processing of picking up, amplifying and filtering the ECG signal.

[0016] figure 2 It is an implementation scheme of the ECG measurement circuit. Among them, the signals picked up by the first electrode 1 and the second electrode 2 are differentially amplified by the differential amplifier to obtain...

Abstract

The invention provides a contact-type wireless cardiac electricity measuring device, which belongs to the field of household medical instruments. The contact-type wireless cardiac electricity measuring device integrates contact electrode technique with Bluetooth technique, is a contact-type Bluetooth cardiac electricity measuring device characterized in that the device meets the need of immediate electrocardiograph (ECG) measurement, can be used at home with low cost and convenient and rapid operation, and can transmit ECG data to a Bluetooth mobile phone which in turn sends the ECG data to a medical service center in time. The device comprises a SCM (6) connected with a data memory (7), a Bluetooth module (8) and a display unit (9) respectively through the serial interfaces inside the SCM; a cardiac electricity measuring circuit (3) with a signal input terminal connected with the SCM (6) through a DAC (5) inside the SCM and a signal output terminal connected with the signal input terminal of an ADC (4) inside the SCM (6); a first electrode (1) and a second electrode (2) respectively connected with the signal input terminal of the cardiac electricity measuring circuit (3), and a keyboard (10) connected with an I/O interface inside the SCM (6).

Description

technical field [0001] The invention relates to a household medical instrument. Aiming at the need for immediate electrocardiogram measurement, a contact-type Bluetooth electrocardiogram measuring device is proposed in combination with contact-type electrode technology and Bluetooth technology, which is oriented to family applications. The system cost is low and can measure electrocardiogram conveniently and quickly. Data, transmit the data to the mobile phone that supports Bluetooth function, and send the ECG data to the medical service center in time through the mobile phone. At the same time, the ECG data can also be transmitted to terminal devices such as PDAs, laptops, and desktop computers that support the Bluetooth function, and the ECG data can be sent to the medical service center through the Internet. Realize remote diagnosis. Background technique [0002] For some heart disease patients, the hospital's routine electrocardiogram examination, and even the dynamic e...
