Example 1
Fig. 3-4 show an earphone with single-lead electrocardiographic detection function according to the present embodiment, through which electrocardiographic detection of standard ii leads in Eithoven triangle principle is achieved.
In this embodiment and in the foregoing background, the left arm, the right arm, the left leg, etc. are all common knowledge in the prior art, and for example, the left arm includes a left upper arm, a left lower arm, a left palm, etc.
The earphone comprises an earphone body 1. The earphone body 1 is of unitary construction (as shown in fig. 3) on which a first electrode sheet 2, which is a negative electrode, and a second electrode sheet 3, which is a positive electrode, are arranged. The earphone body 1 comprises an external part 11 and an in-ear part 12 which are fixed to each other. The wearing of the earphone body 1 is achieved by the insertion of the ear-in portion 12 into the ear canal of the ear or by hooking onto the ear. The aforementioned first electrode sheet 2 is mounted on the in-ear portion 12 with a contact surface arranged facing the outside of the earphone body 1. The aforementioned second electrode sheet 3 is mounted on the external portion 11 with a contact surface arranged facing the outside of the earphone body 1.
The first electrode sheet 2 and the second electrode sheet 3 may be made of metal or non-metal polymer materials, and have good conductivity and biocompatibility.
The earphone body 1 passes through the in-ear portion 12 to have a right ear wearing state of wearing to the right ear of a human body. In the right ear wearing state, the contact surface of the first electrode sheet 2 is in contact with the right ear. And in the right ear wearing state, the second electrode sheet 3 has an exposed position where the left arm of the human body can be contacted. The finger and other parts of the left arm are contacted with the contact surface of the second electrode plate 3, so that the first electrode plate 2 of the negative electrode and the second electrode plate 3 of the positive electrode are connected into the same measuring circuit, and the potential difference between the left arm and the right ear can be measured to form electrocardiographic data.
The earphone body 1 of the present embodiment is mounted with a control circuit board 6, and the aforementioned measuring circuit is formed on the control circuit board 6. The first electrode pad 2 and the second electrode pad 3 are electrically connected to the control circuit board 6, respectively. The control circuit board 6 is provided with an ECG processing chip, a Bluetooth module, a power module and other components. All components on the control circuit board 6 are existing components, and the arrangement mode and the functions of all components on the control circuit board 6 are all of the prior art. During measurement, the first electrode plate 2 and the second electrode plate 3 measure electrocardiosignals in real time and transmit the electrocardiosignals to the control circuit board 6. The ECG processing chip processes the electrocardiosignals and forms an electrocardiogram.

When the left arm is separated from the second electrode sheet 3, the transmission of the electrocardiographic data is stopped. In the mode, the earphone is worn on the ear of the human body so as to collect the electrocardiograph data of the standard II leads, the earphone is convenient to carry and operate, the electrocardiograph collection is not limited by time and space, and the requirements of electrocardiograph detection are effectively met
