Portable and collapsable electrocardiograph
First Claim
1. A portable electrocardiograph comprising:
- a longitudinal body section provided with a first measuring electrode, said body section having two ends;
a hinge section provided at one end of said body section;
a longitudinal arm section having;
one end portion coupled with said body section via said hinge section such that said arm section is movable between two positions corresponding respectively to a folded state and an unfolded state in relation to said body section, said arm section extending from said body section when said arm section is in said unfolded state; and
another end portion; and
a second measuring electrode provided on said another end portion of said arm section and on a surface of said arm section facing said body section when said arm section is in said folded state wherein said arm section is folded onto said body section, andwherein when said arm section is in the unfolded state with respect to said body section a portion of said body section on which the first measuring electrode is provided is held by a hand of a user such that the hand of the user contacts the first measuring electrode, and said second measuring electrode is in contact with a chest of the user, when cardiographic waves are measured.

Abstract
In a portable electrocardiograph, a first measuring electrode that is to be held by a hand during measurement and comes into contact with the palm is provided on a body case. A second measuring electrode that to be pressed against the chest is provided on an arm member provided on the body case in foldable manner. The arm member is placed on the surface facing the body case when the arm member is folded onto the body case. Therefore, to measure electrocardiographic waves with this electrocardiograph, the user has only to slide the arm member into the opening between buttons on the front of his or her clothes or the opening in the shirt at the armpit, and then contacts the second measuring electrode with his chest for measurement. Therefore, it is not necessary to apply the apparatus perpendicularly to the chest. The user has only to place the apparatus almost in parallel to the chest and press the second measuring electrode against the left side of the heart in the chest. As a result, the user need not take off his or her clothes and can measure electrocardiographic waves easily and make quick measurement in case of heart attack. Furthermore, accurate measurement can also be effected.
