Abstract

A portable electrocardiograph which comprises a processing unit for outputting a display command signal for the display of an electrocardiographic wave, a display unit responsive to the display command to display the electrocardiographic wave, and a transparent touch panel assembly disposed above the display unit and having a pattern of scales defined thereon for facilitating a reading of the electrocardiographic wave displayed on the display unit.

Claims

1. A portable electrocardiograph which comprises:

processing means for outputting a display command signal for the display of an electrocardiographic wave;

a display unit responsive to the display command to display the electrocardiographic wave; and

a transparent touch panel assembly located above and in partial contact with the display unit and having a pattern of scales defined thereon for facilitating a reading of the electrocardiographic wave displayed on the display unit beneath the transparent touch panel assembly.

2. A portable electrocardiograph which comprises electrode means adapted to be attached to the skin of a living body for detecting and outputting an electrocardiographic signal produced by the living body, and a main body for processing the electrocardiographic signal supplied from the electrode means, said main body comprising:

processing means responsive to the electrocardiographic signal from the electrode means and a keyed-in position signal supplied from a key-in input unit to perform a process for outputting various display commands according to a predetermined processing program, said display commands being used to display an electrocardiographic wave and key operating symbols on the basis of the electrocardiographic signal and the keyed-in position signal;

a display unit operable in response to the display commands to display the electrocardiographic wave and the key operating symbols; and

a transparent touch panel assembly located above the display unit and including the key-in input unit defined at a location where the key operating symbols are displayed, said touch panel assembly being operable to provide the keyed-in position signal to the processing means in response to a manipulation of the key-in input unit.

3. The portable electrocardiograph as claimed in claim 2, wherein the main body further comprises a storage unit for storing a processed output from the processing means and wherein said processing means is operable to cause the display unit to display the key operating symbols for prompting input of a condition of ECG measurement during the actual ECG measurement, and said processing means also being operable to cause the storage unit to store display commands corresponding to the condition of ECG measurement and the electrocardiographic wave appropriate to such condition.

4. The portable electrocardiograph as claimed in claim 2, wherein the key operating symbols include, inter alia, a key operating symbol for avoiding any possible erroneous operation, and wherein the main body further comprises a function key which, when manipulated during an ECG measurement, causes the key operating symbol for avoiding any possible erroneous operation to be displayed on the display unit.

5. A portable electrocardiograph comprising:

electrode means adapted to be attached to the skin of a living body for detecting and outputting an electrocardiographic signal produced by the living body;

a main body for processing the electrocardiographic signal supplied form the electrode means, said main body comprising a processing means responsive to the electrocardiographic signal from the electrode means and a keyed-in position signal supplied from a key-in input unit to perform a process of outputting various display commands according to a predetermined processing program, said display commands being used to display an electrocardiographic wave and key operating symbols on the basis of the electrocardiographic signal and the keyed-in position signal;

a display unit operable in response to the display commands to display the electrocardiographic wave and the key operating symbols; and

a transparent touch panel assembly located above the display unit and including the key-in input unit defined at a location where the key operating symbols are displayed, said touch panel assembly being operable to provide the keyed-in position signal to the processing means in response to a manipulation of the key-in input unit; and

an IC card adapted to be removable loaded to the main body according to a particular application, said IC card comprising a storage unit for storing the predetermined processing program corresponding to contents of operation of the key-in input unit on the touch panel assembly, said predetermined processing program being adapted to be read out by the processing means.
