Abstract

The present invention provides a palm type electrocardiograph having a case, in which a push button is provided at the front side thereof, a USB port is installed along a lateral side thereof, and two metal holes are assembled at the back thereof. A conductive sticker is also designed with two metal electrodes being penetrately assembled in the center thereon. The conductive sticker has three layers, the first layer is foam, the second layer is conductive graphite, and the third layer is conductive adhesive. An internal circuit is provided in the palm type electrocardiograph, including a microprocessor, an A/D converter, a program memory and a flash memory.

Claims

1. A palm type electrocardiograph, comprising:

a case, wherein a push button is provided at the front side thereof, a USB port is installed along a lateral side thereof, and two metal holes are assembled at the back thereof;

a conductive sticker, wherein two metal electrodes being penetrately assembled in the center thereon;

an internal circuit, including a microprocessor, an A/D converter, a program memory and a flash memory.

2. The palm type electrocardiograph according to claim 1, wherein the conductive sticker has three layers, a first layer is foam, a second layer is conductive graphite, and a third layer is conductive adhesive;

the conductive graphite and the conductive adhesive are each formed into two pieces, and the two metal electrodes are each penetrately assembled respectively through the two pieces so that the two metal electrodes do not short;

the conductive adhesive contains AgCl.

3. The palm type electrocardiograph according to claim 1, wherein after the two metal electrodes are plugged into the two metal holes respectively and the conductive sticker is attached around a human heart, push the push button so that the internal circuit accepts electrocardio signals via the two metal electrodes for processing and storing in the flash memory;

thereafter a USB wire can be used for connecting the USB port and a computer to display the electrocardio signals stored in the flash memory.

4. The palm type electrocardiograph according to claim 1, wherein a microprocessor PS 2101 of Phison Electronics Corp. is used to act as said microprocessor of the palm type electrocardiograph;

AD8607ARMZ (A/D converter) and AD7468BRTZ (amplifier) of ADI Company are used to function as the A/D converter;

EN29LV512 (EEPROM) of Eon Silicon Solution Inc. is used to act as the program memory;

TH58NVG2S3BTG00 of TOSHIBA is used to function as the flash memory;

a rechargeable battery UP042035-PK1 of Usance Technology Co., Ltd is used as a direct current power supply.

5. The palm type electrocardiograph according to claim 3, wherein a operation steps of the palm type electrocardiograph is as follows:

first to push the push button for enabling power;

a program begins accepting electrocardio signals via the two metal electrodes;

the electrocardio signals is processed in the miroprocessor and stored in the flash memory;

if a push button signal is received again, it means that a user stops the operation, so the program terminates;

if no push button signal is received, then calculate if electrocardio signals are recorded for five minutes, if five minutes are reached, stop the operation, otherwise continue recording.
