Illustratively, the number of the first electrodes 61 ' is one, and the number of the second electrodes 61 "is one, when the electrocardiogram is to be mapped, the user can touch one of the first electrodes 61 ' and one of the second electrodes 61" with two hands, and the user can touch the first electrodes 61 ' with one hand and the second electrodes 61 "with one leg. For another example, the number of the first electrodes 61 ' is two, the number of the second electrodes 61 "is two, and the user can contact the two first electrodes 61 ' with two hands and the user can contact the two second electrodes 61" with the user's legs. The greater the number of detection electrodes 61, the more body parts of the user that are in contact with the detection electrodes 61, the more different body parts of the user can be measured, and the more accurate the electrocardiogram can be plotted. By measuring the second electrical signals of a plurality of different body parts of the user in order to form a more accurate electrocardiogram.

It should be noted that if the detecting electrodes 61 on the same side of the housing 10, for example, the plurality of second electrodes 61 "directly contact the wrist, arm, chest or leg of the user, the plurality of detecting electrodes 61 may measure the electric potential of the same portion, so that one of the plurality of detecting electrodes 61 may be used to eliminate the power frequency interference, so that the mapped electrocardiogram is more accurate.

In one embodiment, referring to fig. 1-6, at least a portion of the head 32 extends out of the housing 10, and the head 32 and each of the first electrodes 61' are located on the same outer side of the housing 10. For example, the stethoscope head 32 is located on the outer side of the side plate 11 where each first electrode 61' is located. In this manner, the stethoscope head 32 is prevented from interfering with the second electrode 61 ", which facilitates the contact of the second electrode 61" with body parts of the user, such as the legs and chest.

In one embodiment, referring to fig. 1 to 5 and fig. 7, the housing 10 is formed with a light-passing port 10a, the oximeter 40 includes a light-emitting structure 41 and a light-receiving structure 42 both disposed at the light-passing port 10a, the light-emitting structure 41 emits the emitted light through the light-passing port 10a, a portion of the emitted light is absorbed by the user, another portion of the emitted light is emitted to the light-receiving structure 42 through the light-passing port 10a, and the light-receiving structure 42 converts another portion of the received emitted light into the third electrical signal.

Since each beam of emitted light irradiates the body surface of the user, the absorption of the emitted light by muscles, bones, veins and other connective tissues is basically unchanged (provided that the measurement part does not move greatly), but the absorption of the emitted light by arteries is changed because the artery has blood pulsation during the heartbeat, and the absorption of the emitted light by the contraction and expansion of the artery blood vessels is changed, therefore, when the emitted light enters the body through the body surface, part of the emitted light is absorbed by the human tissue to generate attenuation, and the other part of the emitted light is reflected and then emitted to the light receiving structure 42 through the light transmitting port 10a, the light receiving structure 42 converts the other part of the received emitted light into a third electric signal, and the absorption of the emitted light by the arteries is changed and the absorption of the emitted light by other tissues is basically unchanged, therefore, the heart related condition of the user can be obtained by measuring the loss of the emitted light by using the above principle, for example, the control board 20, such as the processor, processes the third electrical signal to obtain a blood-related biological index of the user, such as a blood pressure index, a heart rate index, and/or a blood oxygen index, etc. The above method for determining a blood related biological index of a user by measuring the loss of emitted light is called Photoplethysmography (PPG). The processor can reduce or eliminate the noise of the third electrical signal to obtain the desired blood oxygenation information. The processor may send the blood oxygen information to the display screen 70, and the blood oxygen information is displayed through the display screen 70, so that the user can visually know the health condition. The processor may also send the blood oxygenation information to the memory for storage. The processor can also transmit the blood oxygen information to the electronic equipment or the medical management system through the communication module.

The cover 43 has a simple structure, and the cover 43 and the light-blocking member 45 can be made of opaque materials, so as to prevent the emitted light emitted from the light-emitting structure 41 and the other part of the received emitted light from being transmitted out of the cover 43 by the light-receiving structure 42 to affect the measurement result. The light-shielding member 45 separates the accommodating cavity 40a into a first cavity 40a 'and a second cavity 40a ", so as to prevent the light in the first cavity 40 a' and the light in the second cavity 40a ″ from influencing each other.
